How to use
Solo Accounting turns each month's bank and credit card statements into a Profit & Loss and a Balance Sheet, checked to the cent, on your own Windows computer. This page shows who it is for, why it helps, and how to use it step by step.
At a glance
A good fit
- One or two owners, or a small S or C corporation
- A monthly statement for each business bank account and credit card
- A Windows computer
Not a fit
- Working out paychecks yourself
- Inventory to track
- Invoices to send, or bills to keep track of
Every month: download your statements, import each one, tell the app what each line was, finish the statement, and read your reports.
The monthly routine, step by step · Who it is for · Why use it · First-time setup
Who it is for
Solo Accounting keeps the books for a small business run by one or two people who are not accountants. It is a good fit when:
- The business is one of these:
- One owner: a sole proprietor or a one-owner LLC.
- Two owners: spouses who own it together, or two partners (a partnership or two-member LLC).
- A small S or C corporation with one or two shareholders.
- Business money moves through a few bank accounts and credit cards, and you get a statement for each one every month.
- Payroll, if you have any, is run by a payroll service (the app records what the service takes out, split into pay and taxes), and you have no inventory to track.
- You count money when it actually comes in or goes out, on a January–December year.
- You use a Windows computer.
- You want tidy books all year and an easy hand-off to your tax preparer.
Not a good fit if you need to…
- run payroll or work out paychecks yourself;
- track inventory or the cost of goods you sell;
- send invoices, or track who owes you and whom you owe;
- have several people working in the books at the same time, or more than two owners;
- work on a Mac (the app runs on Windows only);
- work in a currency other than US dollars.
Solo Accounting also does not file tax returns or work out how much tax you owe. It gets the numbers ready for the person who does.
Why use it
- One pass a month
- Telling the app what a statement line was records it and checks it off against the bank at the same moment. You never type a transaction in and then match it up later.
- Your statements come straight in
- Save the PDF statement from your bank's website and drop it in. Virginia Credit Union business checking and Chase credit card statements are read directly. Other banks' PDFs often work through a general reader, which accepts one only when its numbers add up. If one doesn't, a CSV, OFX, QFX or QBO download from any bank works instead.
- It has to add up, to the cent
- Before anything is saved, the app checks that the starting balance plus the month's activity equals the ending balance printed on the statement. When it doesn't, it tells you and points at the likely cause.
- Nothing is counted twice
- A payment from checking to your credit card shows up on both statements. The app matches the two sides, so the payment is recorded once and never looks like an expense.
- It learns your categories
- Once you have filed a payee under a category, the app suggests it next time. Most lines become one click.
- Organized the way your tax form is
- Every category is tied to the line of the tax form it belongs on, and in the Transactions export the category rows show their tax line for your preparer.
- Reports that are always current
- Profit & Loss and Balance Sheet are up to date the moment you record a line, and the Balance Sheet proves it balances with a check line at the bottom.
- Easy to fix
- Undo, reopen a finished statement, or delete a whole import. Every change is kept in a change history, so nothing is ever silently lost.
- Your data stays yours
- Your books live on your computer, with automatic backups. Keep the app folder in OneDrive, or add a second backup folder, and the backups are also kept off your computer. No bank passwords, no connection to your bank, no subscription.
The big picture
Every month follows the same five steps.
- StatementsDownload last month's statement from each bank and card website.
- ImportDrop each file on its account's card on Home. The app checks that it adds up.
- ReviewTell the app what each line was. Choosing records it.
- FinishWhen nothing is left and the difference is $0.00, finish the statement.
- ReportsProfit & Loss and Balance Sheet are up to date.
First-time setup
Setup takes about ten minutes. If you have them, keep the last statements from before your start date nearby. You can also leave starting balances blank (see step 7).
- Install once. In the Solo Accounting folder, double-click
install.cmd. It sets up what the app needs to run (downloading it the first time, if this computer does not have it) and puts a "Solo Accounting" shortcut on your desktop. You do this once per computer. - Start the app. Double-click the "Solo Accounting" shortcut on your desktop. Your web browser opens the app. It runs on your computer only.
- Say who owns the business. Under "Who owns the business?" pick "Just me", "Me and my spouse" or "Me and one partner".
- Pick how the business is set up for taxes. The choices follow your answer: "Sole proprietor", "One-owner LLC", "Partnership or LLC (Form 1065)", "No corporation election", "S corporation" or "C corporation". Each one has a one-line explanation under it.
- Name the business and its owners. With two owners, enter each one's share.
- Pick the start date. Most people start on January 1. If you start later in the year, a "Before you started" step asks for totals for the earlier months from your own records, so the year's reports are complete.
- Add your accounts. Add every business bank account and credit card you will import statements for, with "+ Add another bank account" and "+ Add another credit card". For each one give its name, the bank or card company, the last 4 digits, and its starting balance: the balance at the end of the day before your start date (for a card, what you owed). For a bank account, that is usually the ending balance of the statement that ends that day. For a card, also give the day of the month its statement closes.
Leave the starting balance blank if you don't have that statement, or for a credit card whose statement does not end the day before your start date (what you owed on that exact day is on no statement). Your first statement fills it in for you.
- Corporations only: starting balances. The "Company's starting balances" step asks "Was the company already running before your start date?" If yes, copy the figures from last year's return or your formation papers.
- Check and create. The last step lists your answers. Click "Create my books". Home opens with one card per account.
Not sure about an answer?
- Pick the closest answer and keep going. Most of it can be changed later in Settings.
- Not sure about the tax setup? If the business never filed IRS Form 2553 or Form 8832, it is not a corporation. Then pick "Sole proprietor" or "One-owner LLC" (just you), "No corporation election" (you and your spouse), or "Partnership or LLC (Form 1065)" (you and a partner). Check with your accountant.
- An LLC or partnership that later becomes a corporation can switch with "Change the business type…" in Settings. A sole proprietor that incorporates starts a new business file.
- A starting balance you are not sure of can be fixed later in Settings, under Accounts.
Adding an account later
Opened a new card? In Settings, under Accounts, open "Add an account", fill it in and click "Add account". Then click "Set starting balance" for it, or leave it for the first statement to fill in. Its card appears on Home, ready for its first statement.
The monthly routine
Order that works best: checking then card, oldest month first.
How long it takes: about 20 minutes a month once it has learned your categories. The first month takes longer, because every payee is new.
- Download your statements. From each bank and card website, save last month's statement as a PDF. For a bank whose PDF is not read cleanly, download that statement's dates as a CSV, QFX, OFX or QBO file instead. These files often leave out the ending balance, so keep the statement's ending balance handy: you type it in at step 3.
- Click "Import" on the account's card on Home, and pick the file. You can also drag the file onto the card. Start with checking.
-
Read the preview. Nothing is saved yet. Look for these:
- The tie line. It adds the starting balance and the month's activity and compares the result with the statement's own ending balance. A ✓ at the end means it adds up to the cent. For example: Opening $1,000.00 + activity $250.00 = $1,250.00 · Bank balance as of Jan 31, 2026: $1,250.00 ✓ For a card it reads "You owe" instead of "Bank balance".
- Rows read. For a PDF, a line such as 24 transaction rows seen on the pages, 24 read ✓ means every row on the paper was read.
- A file without a balance (common with CSV, OFX, QFX and QBO). The tie line ends with "Balance not verified". Type the ending balance printed on the statement next to "Balance from the statement", check the date, and click "Check". The tie line then shows ✓. You can also type it later, at the top of Review.
- A PDF that doesn't add up. The preview lists the likely causes. If you can't find why, you can tick "Import anyway, unverified" and check every line yourself. Such a statement can only be finished with "Finish (balance not verified)" until its balance ties.
- First statement for an account. If you left its starting balance blank, the preview works it out from the statement and shows it, marked "will be used". Change it only if you know it is wrong. For a file without balances (many CSV downloads), the preview asks for it instead: type it and click "Use this".
- A starting balance that doesn't match. If the preview says the statement opens at a different amount than the account's starting balance, fix the starting balance in Settings, under Accounts, and import the file again.
- A statement that starts before your books. You get two buttons: "Leave out lines before" your start date, or "Move my start date to" the statement's first day. One is marked "(recommended)". If your books start January 1 and a card statement runs from Dec 21 to Jan 20, leave out the December lines: they belong to last year's books.
- A missing period. If this statement does not start where the last one ended, the preview says which days are missing. Import that statement first, or type the balance at the start of this one and click "Fill the missing period".
- Wrong account. If the file looks like it belongs to a different account, the preview warns you. Click "Start over", choose the right account in the "Account" list and pick the file again (or go "Back to Home" and use that account's card).
- Click "Import & Review". A backup is made first, then the Review screen opens with every line of the statement. At the top you see "Remaining" and "Unexplained difference".
-
Record each line. Choosing what a line was records it. Work down the list:
- Accept suggestions. A line the app recognizes shows its guess in the Category field with a "✓ Accept" button ("✓ Accept match" when it matched something already recorded). The button above the table, such as "Accept 12 suggestions", records them all at once, and one "Undo" takes them all back. A "✓ Accept?" button is a guess: it is never included in the accept-all button, so check it and accept it yourself.
- Choose a category. Click the Category field ("Choose a category") and pick from the list, or type a few letters to narrow it down.
- Quick picks. Under the highlighted line, "Quick pick:" shows your most-used categories. Click one or press its number, 1 to 9.
- Card payments and transfers. Paying the credit card from checking, or moving money between your own accounts, is not an expense. It is under "Move money" in the list, and the suggestion usually reads "Payment to" and your card's name. On a line that looks like a payment, the quick pick 0 picks it. Or type pay or transfer in the Category field.
- Personal spending and money you put in. A personal purchase on the business card, or money moved between your personal and business accounts, is "Owner money" ("Shareholder money" for a corporation).
- One line, several categories. Choose "Split…", give each part a category and an amount (or a percentage), and click "Record split" once it says "Adds up ✓". Next month the app offers the same split.
- Not sure? Choose "Ask my accountant" and keep going. Clear these with your accountant before the year is done.
- Exclude, rarely. "Exclude…" is only for a bank duplicate or reversal, or a row that is not a real transaction (such as a pending item). Never exclude personal spending: that is Owner money.
Each line also has a ⋯ menu with Split, Exclude, Ask my accountant, Owner money and a note. Need a break? "Save and come back later" keeps everything you have done.
-
Click "Finish statement". When "Remaining" is 0 and "Unexplained difference" reads "$0.00 ✓", click "Finish statement". The statement is marked reconciled, a backup is written, and its lines are frozen until you reopen it.
If the ending balance was never typed in, "Unexplained difference" reads "Balance not verified" and the button reads "Finish (balance not verified)": the statement is finished but not proven. Type the balance there later, and once it ties the statement is reconciled.
- Do the credit card next. Import the card statement the same way. The payment you recorded from checking shows "✓ Accept match" on the card's payment line. Accept it: it is the same money, recorded once.
- Check Home. Each account card shows "Reconciled through" the statement's last day. "To do" lists anything that still needs you. Once every account is finished through the end of a month, "How the year is going" shows that month's income, expenses and profit.
Things not on a statement
Some business money never touches a business account. Record it with "Add manual entry" on Home or Transactions. Most months need none, or just one or two.
| Choose | When to use it |
|---|---|
| "Business expense I paid personally" | You paid a business cost with cash, a personal card, Zelle, Venmo, or anything else that is not a business account. It counts as money you put into the business. |
| "Cash sale" | A customer paid in cash and you kept it as business cash. |
| "A customer paid me personally" | A customer paid you and the money never went into a business account. |
| Under "More…" | |
| "Expense paid from cash on hand" | You paid a business cost from the cash you keep for the business. |
| "Check I wrote that isn't on a statement yet" | Only if you want it in the books before the bank shows it. Most people wait for the statement. |
| "Deposit I made that isn't on a statement yet" | The same, for a deposit. It matches up when the statement arrives. |
| "Transfer between accounts not yet on a statement" | Money moved between two of your accounts that neither statement shows yet. |
| "Owner put money in / took money out in cash" | Cash that moved between you and the business. |
Mileage, home-office and receipt tracking are not in the app yet. Keep your own log of those for your preparer.
Reading your reports
Open the Reports tab. Click a category or account name to see the transactions behind it. "Print" prints the report and "Export CSV" saves it for a spreadsheet.
"Profit & Loss": what you earned and spent
Pick a period, such as "This month", "This year" or "Last year". Income is at the top, expenses below, and the bottom line is "Net profit", or "Net loss" when you spent more than you earned. Owner money and transfers never appear here, because they are not income or expenses.
While any lines are still in Ask my accountant, the bottom line reads "Net profit before uncategorized items" (or "Net loss before uncategorized items"), followed by "Not yet categorized (Ask my accountant)" and their total.
"Balance Sheet": what the business has, owes, and your stake
Pick a date. The report lists "What the business has" (bank balances, cash, equipment), "What the business owes" (credit cards, loans), and "Owner's stake": what you put in, took out, and the profit the business has made.
The last line is the check line. It proves that what the business has equals what it owes plus your stake. A ✓ means the books balance. They always should; if they ever don't, the report tells you what to do.
Under each bank and card account is a short note such as Per statement $1,250.00 (as of Jan 31) · uncleared -$80.00 (1 item) · book $1,170.00. "Per statement" is what the last statement said, uncleared is what you have recorded that the bank has not shown yet (a check not cashed), and book is the balance in your records.
"Owner's stake": each owner's year
Pick a year to see, for each owner, the starting stake, money put in, money taken out, share of the profit, and the ending stake. A corporation sees "Shareholders' equity" instead.
Fixing mistakes
- Undo the last thing
- In Review, click "Undo" (or press Ctrl+Z). An accept-all comes back as one step. Undo works until you finish the statement.
- Change a category after the fact
- While the statement is open, click "All" above the table (recorded lines are hidden under "Remaining"). Then use the line's ⋯ menu, choose "Un-record this line", and choose again. Or open the Transactions tab, click the transaction, change the category, payee or note, and click "Save". Amounts and dates from the bank never change.
- Change a finished statement
- In Review, open "More ▾" and choose "Reopen statement…". Make the change, then click "Finish statement" again. Later statements check themselves again.
- Wrong file, or the wrong account
- In Review, open "More ▾" and choose "Delete this import…". Lines you already recorded are un-recorded first, then the whole statement is removed. Import the right file on the right card. A finished statement has to be reopened first ("Reopen statement…").
- See what changed
- Settings has a "Change history" of everything, newest first. Each transaction also shows its own history when you open it.
When "Unexplained difference" is not $0.00
It means your records for this statement do not match the bank's ending balance, by that amount. The app never hides the gap with a made-up entry. Click "Why?" next to the amount for the likely causes, then check, in this order:
- A line you excluded that the bank did count.
- The ending balance: is it the one printed on the statement, as of the statement's last day?
- The starting balance of the account (Settings, under Accounts), or an earlier statement that is missing.
- An earlier statement of this account that was reopened and changed.
Backups and your data
- Where your books live. Each business is one file on this computer, in the SoloAccounting folder inside your user folder. It is kept out of OneDrive on purpose: a file that is in use can be damaged while it syncs.
- Automatic backups. Copies are saved to the Backups folder inside the Solo Accounting app folder (Settings, under Backups, shows exactly where): before each import, after you finish a statement, every hour while you work, when you quit, and before an app update. If the app folder is in OneDrive, OneDrive keeps the backups off your computer too. If it is not, set a second backup folder (below).
- Back up by hand. Settings, under Backups: click "Back up now".
- Go back to a backup. Settings lists your backups, newest first. Click "Restore" next to one. Everything entered after that backup is gone from the books, and a safety copy of the current file is saved first.
- A second copy. Put a USB drive, a OneDrive folder or another folder in "Second backup folder" and click "Save folders". Every backup is copied there too.
- Quit. Click "Quit" at the bottom of Home or on Settings. It writes a backup and stops the app. Closing the browser tab does not stop it; it stops by itself after 12 hours of not being used.
If the backup folder cannot be found (for example, it was moved or renamed), backups go to a fallback folder on this computer and Settings tells you so.
Year-end and taxes
What you can give your preparer today
- Finish every statement through December. The card statement that runs into January holds December charges, so import it too.
- Clear Ask my accountant. On the Profit & Loss for "Last year", click "review" next to "Not yet categorized (Ask my accountant)" to see those lines. Decide each one with your accountant and change its category.
- Print or export the reports. "Profit & Loss" for "Last year" and "Balance Sheet" for "Dec 31 last year", with "Print" or "Export CSV". The Transactions tab has "Export CSV" for every transaction, and the category rows show their tax line.
- Show the tax lines. Settings, under Categories, shows each category's "Tax line", the line of the tax form it belongs on.
Coming later
A Year-end checklist, locking a finished year, and a one-click Tax Package folder for your preparer. The "Year-end" tab is a placeholder until then.
Solo Accounting never files a return, never works out the tax you owe or your estimated payments, and never calculates depreciation or payroll.
For a sole proprietor, LLC or partnership, your own estimated tax payments made from the business account are recorded under Owner money (the "Estimated tax payments" entry), never as a business expense. Corporations: see S and C corporations.
S and C corporations
- "Shareholder money" instead of Owner money. In an S corporation, money you take out is a distribution; in a C corporation it goes to your loan account (you owe it back unless your preparer calls it a dividend or pay). "Dividend" is there for dividends that were actually declared.
- Money you put in is a loan by default. It is recorded as a loan from you to the company, which the company can pay back. Choose another entry under Shareholder money if you put it in for good.
- Payroll is recorded, never calculated. When your payroll service takes money out, the line is marked "Payroll". Choose "Split…" and copy the numbers from that run's payroll report into rows such as "Net pay", "Employee taxes (withheld from pay)" and "Employer taxes". IRS payroll-tax deposits work the same way.
- Tax payments. A C corporation's own income-tax payments are an expense of the company: choose "Corporation income tax – federal" or "Corporation income tax – state". The Profit & Loss shows them below "Profit before income tax". A shareholder's personal estimated tax paid from the company account is Shareholder money.
- Retained earnings. The Balance Sheet shows "Shareholders' equity", with "Retained earnings" (profit the company has kept) and any loans to or from shareholders.

Questions and answers
The difference is not $0.00. What do I do?
Click "Why?" next to "Unexplained difference" in Review for the likely causes. Then go through the checklist under Fixing mistakes. The most common causes are an excluded line the bank did count, and a starting balance that is off.
A statement starts before my books do.
The preview offers "Leave out lines before" your start date, or "Move my start date to" the statement's first day, and marks one "(recommended)". If your books start January 1, leave the old lines out: they belong to last year's books.
I skipped a month.
The account's card on Home shows "Missing period" with the days. Import the skipped statement; a statement can only be finished after the earlier ones are. If you cannot get that statement, click "Fill the missing period" and type the balance at the start of the newer statement. One summary line then covers the gap and waits in Ask my accountant until you categorize it.
I am catching up on several months.
Go one month at a time, oldest first: that month's checking statement, then its card statement, then the next month. A statement can only be finished after the earlier ones for that account are.
I imported the wrong file, or to the wrong account.
Open that statement in Review, open "More ▾" and choose "Delete this import…" (if you already finished it, choose "Reopen statement…" first). Then import the right file from the right account's card. The preview warns you before import when a file looks like it belongs to another account.
The card payment is on both statements. Is it counted twice?
No. The same money leaves checking and arrives at the card. Record the checking line as the payment to the card (under "Move money"). On the card statement, the matching line shows "✓ Accept match": accept it and it is recorded once. If you filed the checking line as an expense by mistake, un-record it and choose the payment instead.
How do I record a refund or a return?
Give it the same category as the purchase. It lowers that expense, which is what you want.
I bought something big, like a computer.
Record it like any purchase. For a large amount the app may ask whether it belongs in "Equipment & large purchases". Ask your accountant how it is handled on your return.
What is "Ask my accountant"?
A parking spot for lines you are not sure about, so they never hold you up. They show on the Profit & Loss as "Not yet categorized (Ask my accountant)". Go through them with your accountant and give each one a real category before the year is done.
What does "Owner money" mean?
Money moving between you and the business that is not income or an expense: personal purchases made with business money, money you put into the business, and your own estimated taxes. It does not change your profit; it shows in your stake on the Balance Sheet and on "Owner's stake". A corporation calls it "Shareholder money".
Can I change my business type later?
An LLC or partnership whose corporation election was accepted by the IRS can switch in Settings with "Change the business type…". The change starts on a January 1, and earlier years stay as they were. A sole proprietor that incorporates starts a new business file, because the corporation is a new company. Ask your accountant before you change it.
Can I use it on two computers?
It is made for one person on one computer at a time. To move to another Windows computer, copy or sync the Solo Accounting app folder there and run install.cmd (see First-time setup). Make sure your newest backup is in that folder's Backups folder: OneDrive does this for you if the app folder is in OneDrive; otherwise copy the backup there. Then open the Restore page: on a computer with no business file yet it says "Restore from a backup" and lists the backups it found. Click "Restore this" next to the newest one. Don't keep working on both computers: changes on one never reach the other.
My bank isn't Virginia Credit Union or Chase.
Try its PDF statement anyway. The general reader accepts it only when the numbers add up, and tells you if they don't. If it can't read it, download the same dates as a CSV, QFX, OFX or QBO file. If the app doesn't recognize a CSV's columns, it asks "Which column is which?" once and remembers your answers for next time.
My statement is a scanned picture.
A scanned (image-only) PDF can't be read. Download a CSV, QFX, OFX or QBO file for the same dates from your bank's website instead.
Words used in the app
- Reconcile
- Check your records against the bank's statement until they agree, to the cent. Here, recording each line does it, and a finished statement that ties shows "Reconciled".
- Statement line
- One row of a bank or card statement: a date, a description and an amount.
- Category
- What a line was: a kind of income or expense, such as Supplies. Each category is tied to a tax-form line.
- Owner money
- Money between you and the business that is neither income nor expense. For a corporation: Shareholder money.
- Transfer / Move money
- Money moving between two of your own business accounts, including paying the business credit card.
- Uncleared
- Something you recorded yourself that has not shown up on a statement yet, such as a check that has not been cashed.
- Starting balance
- An account's balance right before your books start (for a card, what you owed). Left blank, the first statement fills it in.

- The app has not been given the statement's ending balance yet, so it cannot prove the statement adds up. Type the balance in Review to prove it.
- Check line
- The last line of the Balance Sheet: what the business has equals what it owes plus your stake. A ✓ means the books balance.
- Ask my accountant
- A holding place for lines you are not sure about. It must be empty before the year's numbers go to your preparer.
