If you need catch-up bookkeeping, there’s a good chance your records aren’t perfectly organized. That’s normal and expected. The goal is to gather what you can so your bookkeeper has enough to reconstruct your financial picture accurately.

Bank statements are the single most important thing you’ll provide. Every business checking and savings account, for every month that needs to be caught up. These are the backbone of the entire process because they show money coming in and going out. Most banks let you download statements going back several years through online banking, so even if you never saved them, you can usually retrieve them.

Credit card statements come next. Every card used for business purchases, for the full period. If you’ve been using a personal card for some business expenses, those statements are needed too. Your bookkeeper will sort out which transactions are business and which are personal.

Prior year tax returns are important because they establish where your books should start. If the last time your records were accurate was two years ago, your most recent filed return gives your bookkeeper a starting point for account balances and any carryforward items. If you’ve worked with someone for business tax preparation in the past, they may have copies of prior returns and supporting documents that help.

Beyond those essentials, here’s what else helps. Loan and financing statements show principal and interest breakdowns your bookkeeper needs to record correctly. Payroll reports from your payroll provider or records of what you paid employees and contractors. Invoices you sent to customers, especially if you have outstanding receivables. Bills and receipts for major purchases like equipment, vehicles, or deposits. Sales tax filings if applicable. And 1099s you received or issued.

If you have an existing QuickBooks file or any accounting software with partial data, provide access to that as well. Even incomplete records give your bookkeeper a head start rather than building everything from scratch.

Don’t wait until you have every single receipt to get started. A skilled catch-up bookkeeping provider can reconstruct most of what happened from bank and credit card activity alone. Receipts and invoices add detail and confirm categories, but the statements tell the main story. The longer you wait trying to find everything, the further behind you fall. Gather what you have, hand it over, and let your bookkeeper tell you if anything critical is missing.
