Catch-up Bookkeeping Document Checklist: What to Gather

The single best thing you can do to make catch-up bookkeeping faster, and usually cheaper, is to gather the right documents before work starts. This checklist covers what a bookkeeper typically needs, why each item matters, and what to do if something is missing.

Don't worry if you can't tick every box. Bank and card statements do most of the work. The rest fills in detail.

What are the must-have documents?

These are the backbone of any catch-up project. Without them, the books can't be reconciled.

Bank statements for every business checking and savings account, for every missing month.
Credit card statements for every card used for business, including any personal card used for business purchases.
Payment platform reports (PayPal, Stripe, Square, Shopify, Amazon, Etsy and similar): payout and fee reports for each month.
Loan and line of credit statements, showing balances, interest and payments.
Your last filed tax return (business and/or personal), so opening balances match what was reported.
Access to your current accounting file (QuickBooks Online, Xero, Wave or other), if one exists.

Tip: Month-end statements in PDF are ideal. Read-only access or bank feeds connected to your accounting software are even better, because they avoid manual entry.

What other records should I gather?

These documents explain the "why" behind transactions. The IRS lists similar supporting documents in its guidance on what kind of records to keep.

Area	What to gather	Why it matters
Sales and income	Invoices, sales reports, deposit records, Forms 1099-NEC, 1099-MISC and 1099-K you received	Confirms income and matches it to what the IRS receives
Purchases and expenses	Receipts, bills, invoices, cancelled checks or proof of electronic payment, account statements	Supports deductions and correct categories
Payroll	Payroll register or summary reports, quarterly payroll tax filings (Form 941 and state returns), year-end W-2s	Records wages, taxes and employer costs correctly
Contractors	List of contractors paid, amounts, W-9s, and any 1099s you issued	Supports expenses and your own 1099 filing obligations
Assets	Purchase and sale invoices, closing statements, proof of payment for equipment, vehicles and property	Needed for depreciation and gain or loss on sale
Inventory	Purchase invoices, year-end inventory counts, supplier statements	Needed to work out cost of goods sold
Sales tax	Sales tax returns filed and payments made, by state	Separates tax collected from your income
Owner activity	Notes on money you put in or took out, and business expenses paid personally	Keeps owner draws and contributions out of profit

What about access and logins?

Catch-up bookkeeping is much faster with access to live data, but share it safely.

Use read-only or "accountant" access where your bank, card or software offers it.
Invite your bookkeeper as a user in your accounting software rather than sharing your login.
Never email passwords, full account numbers or your Social Security number. Agree a secure way to share documents first.
Keep a list of what access you've given, so you can remove it later.

What if some documents are missing?

It's normal. Here's what usually works:

Bank or card statements: download older statements from online banking, or ask the bank for copies. Some banks may only keep a limited history online.
Payment platforms: most let you download monthly reports or transaction histories for past periods.
Receipts: check your email for e-receipts, and ask vendors for past invoices. For small, routine purchases, the bank or card statement often shows enough to categorise the transaction.
Payroll reports: your payroll provider can usually regenerate past reports.
Tax return: you can request a transcript from the IRS through your IRS Online Account.

If something truly can't be found, your bookkeeper will note it. A gap is better recorded honestly than guessed.

How long should I keep these records afterwards?

The IRS says records that support items on your tax return should generally be kept for 3 years. Longer periods apply in some cases: 6 years if you didn't report income that is more than 25% of the gross income shown on your return, 7 years for a bad debt or worthless securities deduction, and indefinitely if you didn't file a return. Keep employment tax records for at least 4 years after the tax is due or paid (IRS). Keep records for property until the limitation period runs out for the year you dispose of it.

How do I organise everything before handing it over?

A simple folder structure saves hours:

Catch-up [Business name]
├── 01 Bank statements / [Account] / YYYY-MM.pdf
├── 02 Credit cards / [Card] / YYYY-MM.pdf
├── 03 Payment platforms / [Platform] / YYYY-MM report
├── 04 Loans
├── 05 Payroll
├── 06 Sales and invoices
├── 07 Receipts and bills
├── 08 Assets and inventory
├── 09 Sales tax
└── 10 Tax returns and IRS letters

Add a one-page note listing every account (name, type, last 4 digits only) and anything unusual: a loan, a big equipment purchase, a period when business and personal spending mixed.

If you have an IRS letter in the pile, check it first. The IRS Notice Decoder tells you what it means and whether there's a deadline.

What happens after I gather everything?

Once the documents are in, the catch-up follows a set order: record, categorise, reconcile, review and produce financial statements. The pillar guide, Behind on Bookkeeping? A No-Judgment Guide to Catching Up, explains each step.

To see what your catch-up might cost, the Catch-up Bookkeeping Cost Estimator gives a beta range based on RAHA's published starting prices. RAHA confirms a fixed quote after a short review of your accounts. Book a free consultation or read about our bookkeeping services.

Frequently asked questions

Can you catch up my books from bank statements alone?

Mostly, yes. Bank and card statements show almost every transaction and are the basis for reconciliation. Receipts and invoices add detail for categories and support deductions, especially for larger purchases.

Do I need receipts for every purchase?

Good records support what you deduct. The IRS lists receipts, invoices, cancelled checks and account statements as supporting documents for expenses. For small, routine purchases, statements often identify the vendor. For larger or unusual items, keep the receipt or invoice.

Should I include personal accounts?

Only if business money went through them. If you paid business expenses from a personal card, include those statements and flag the business items. Going forward, a separate business account makes bookkeeping far simpler.

What if I used spreadsheets instead of software?

Send the spreadsheets too. They help explain transactions. Catch-up is also a good moment to move to accounting software. RAHA offers software selection help.

Is it safe to share bank access?

Use read-only or accountant access where available, invite your bookkeeper as a separate user, and never email passwords or full account numbers.
