Use this monthly handoff list for bank statements, sales reports, invoices, bills, receipts, payroll, and loans so your books can be closed accurately. By [Joe Angerosa](https://pinstripeservices.com/founder) · October 7, 2026 · 5 min read A bookkeeper usually needs bank and credit card statements, sales and payment records, customer invoices, vendor bills and receipts, payroll reports, and documents for loans or unusual transactions each month. The exact list depends on the business, but the rule is simple: provide the records that explain every balance and material transaction. A bank feed alone is not a complete handoff. ## Which monthly documents are essential? Start with statements for every business bank account and card, including accounts with little or no activity. Add reports from payment processors and sales systems, copies or access to customer invoices, vendor bills, expense receipts, payroll summaries, and any loan statements. Your bookkeeper may also need merchant fee reports, inventory records, mileage logs, or project costs depending on what your business does. | Document | Why it matters | Common gap | | --- | --- | --- | | Bank and card statements | Support reconciliation and ending balances | A new or rarely used account is omitted | | Sales and processor reports | Separate gross sales, fees, refunds, and deposits | Only the net deposit is recorded | | Customer invoices | Track revenue and unpaid amounts | An invoice is sent outside the accounting system | | Vendor bills and receipts | Explain expenses and unpaid obligations | A card charge has no business purpose attached | | Payroll reports | Support wages, taxes, and liabilities | Only the bank withdrawal is available | | Loan statements | Separate interest from principal and verify balance | The whole payment is coded as expense | Our [free monthly bookkeeping checklist](https://pinstripeservices.com/monthly-bookkeeping-checklist) turns this into a repeatable handoff. It is useful even if you keep your books yourself. ## Why is a bank feed not enough? A bank feed tells you that money moved. It often does not tell you why, whether the transaction belongs to this period, which customer or vendor it relates to, or whether part of the amount is a fee, tax, loan principal, or owner draw. A $4,850 payment processor deposit could represent $5,000 of customer sales less $150 of fees. Recording only the deposit understates both revenue and fees. The source report and statement let the bookkeeper explain the difference. For the same reason, importing card charges does not prove the purchases were business expenses. The [auto-sync versus bookkeeping article](https://pinstripeservices.com/blog/quickbooks-bank-feed-bookkeeping-mistakes) explains why review and reconciliation remain necessary. ## What should you send for unusual transactions? Flag anything that would be hard for a new reader of the books to identify. Examples include equipment purchases, a new loan, a business acquisition, a refund to a customer, an owner contribution, a personal purchase on a business card, or a transfer between accounts. Include the agreement, invoice, or short explanation that answers what happened. Do this when the event occurs, while the details are fresh. For example, a hypothetical $12,000 bank withdrawal might be a computer purchase, a loan payoff, or an owner distribution. Those have different effects on financial reports. The amount alone cannot choose the category. If you are unsure what to send, provide the supporting document and a sentence of context, then let the bookkeeper ask the accounting question. ## When should the documents arrive? Send routine receipts and bills throughout the month if possible, then supply statements and final reports when the period ends. A consistent handoff date lets the close begin without waiting for a surprise document. If a processor posts late or a statement is not ready, note the expected date instead of letting the item disappear. 1. During the month, save receipts, bills, and unusual transaction notes. 2. At month-end, confirm that all account and card statements are available. 3. Export sales, processor, and payroll reports for the exact period. 4. Review the list for newly opened accounts, loans, and payment tools. 5. Respond to follow-up questions before the reports are finalized. This supports the [monthly bookkeeping close](https://pinstripeservices.com/blog/how-a-monthly-bookkeeping-close-works): receipts in, reconciled, reviewed, and delivered. The sooner the inputs are complete, the sooner the finished numbers can be trusted. ## How should you organize the handoff? Use a repeatable folder structure and clear file names. A statement named with the institution, account suffix, and month is easier to find than “scan3.pdf.” Keep raw source documents; do not replace them with a manually typed summary when the original report exists. Avoid sending the same file through several channels without saying which is final. For Pinstripe clients, [Pinstripe Sync](https://pinstripeservices.com/pinstripe-sync) provides folders inside the client portal for bookkeeping, receipts and expenses, reports, and other work. You can upload documents there and attach a file to a portal message when you have a question about it. The product is a convenient handoff space for our engagement, not a general document storage product for every business workflow. ## What comes back after the handoff? Once the records are complete, the bookkeeper can reconcile the accounts, review exceptions, and deliver reports. The owner should receive more than a stack of numbers: a short explanation of what changed and what needs attention helps turn bookkeeping into a decision tool. Our article on [six numbers to review every month](https://pinstripeservices.com/blog/six-numbers-to-review-every-month) describes the simplest useful view. Pinstripe monthly bookkeeping clients can follow progress in [Pinstripe Close](https://pinstripeservices.com/pinstripe-close) and see the finished summary in [Pinstripe Ledger](https://pinstripeservices.com/pinstripe-ledger). The Ledger snapshot includes a note from the bookkeeper; it does not replace the underlying detailed records. See [how to read the monthly snapshot](https://pinstripeservices.com/blog/how-to-read-a-monthly-financial-snapshot) when the close is done. Our [bookkeeping service](https://pinstripeservices.com/services/bookkeeping) covers the monthly process, while your CPA or tax professional handles tax filing. ## Frequently Asked Questions ### Do I need to send every receipt? Keep support for business expenses and send the records your bookkeeper requests. For charges whose purpose is unclear, a receipt and short note can prevent a wrong category. ### What if my bank account had no transactions? Provide the statement or confirm the account and zero activity. An account missing from the handoff should not be mistaken for an account that no longer exists. ### Can I send photos instead of PDFs? Clear, complete photos often work for individual receipts. Statements and multi-page reports are easier to verify as original PDFs or exports when available. ### Should I send tax documents to my bookkeeper? Send documents that affect the books or that your bookkeeper requests for year-end handoff. Pinstripe does not file tax returns; confirm your CPA's separate list for tax preparation.
