Expense tracking works when you can move from a number in the books to the document explaining it. A list of card charges is a useful starting point, but it may not tell you what was purchased, which company bought it or whether an invoice has already been recorded.
Build the process around collection, review and reconciliation. This guide was refreshed in September 2026 to cover that complete workflow.
What to capture for each purchase
Record the supplier, document date, amount, currency, tax shown, purchasing entity and business purpose. Keep the original receipt or invoice alongside the extracted information. Add the payment reference when available, and distinguish an unpaid invoice from evidence that it was settled.
The IRS recordkeeping guidance explains why records support tax reporting. Do not treat a bookkeeping category as proof that an expense qualifies for a deduction; the facts and applicable rules still matter.
Step 1: collect from the places purchases actually happen
List the inboxes receiving SaaS invoices, travel confirmations and supplier bills. Add the paper receipts captured by employees and owners. Decide how missing documents will be requested and who handles each source.
Receiptor AI can automatically extract receipts and invoices from connected email accounts. WhatsApp and iMessage provide additional submission routes. For a backlog, historical email extraction helps recover older purchase evidence without opening every message manually.
Step 2: assign the legal entity before exporting
A founder may receive receipts for several companies in one inbox. The email address alone is not enough to decide which company incurred a cost. Check the billed name and purchase context, and resolve uncertainty before the document reaches the wrong ledger.
Receiptor supports legal entity distinction and entity-specific accounting connections. That matters when two businesses use the same supplier but maintain separate books.
Step 3: check duplicates and related documents
An invoice, a payment confirmation and a receipt can describe one purchase. A forwarded copy can be another duplicate. Preserve useful evidence while preventing multiple expense entries for the same event.
For example, a $120 software invoice followed by a $120 payment receipt is not automatically $240 of spending. Receiptor's transaction groups and duplicate handling help organize the documents together. Mathematical validation and AI review provide additional checks on extracted information; review unresolved issues before posting.
Step 4: connect documents to accounting and payment evidence
With the relevant plan and configuration, Receiptor can match or create the appropriate Xero Bill, Spend Money transaction or Bill payment. Its QuickBooks integration supports Bills, Expenses and Bill payments. Check the accounting treatment and supporting attachments, rather than judging success only by whether an export completed.
The Mercury integration adds another source of financial context. Broader bank connections are in beta; confirm availability for your account. Payment evidence is useful for matching, but does not by itself explain the business purpose of a purchase.
Step 5: close the loop each month
- Reconcile bank and card balances to the books.
- Investigate purchases with no supporting document.
- Resolve duplicate warnings, unclear entities and unmatched payments.
- Review refunds and credits against the original purchase.
- Save the final reports and keep an accessible copy of the evidence.
Choose software using a small, realistic trial
Test ten ordinary receipts plus an invoice paid later, a foreign-currency purchase, a duplicate and a refund. Include two entities if you operate more than one. Count the items that still need correction and inspect the accounting output.
A spreadsheet may be sufficient at low volume if someone maintains it consistently. An accounting tool's built-in capture may also meet your needs. Receiptor is particularly relevant when collection across inboxes, historical recovery and document review create more work than entering the final transaction. Review current plans against that workflow, rather than buying on scan counts alone.
