Start with the question
Are you checking demand, issued invoices, cash, supplier commitments or incurred costs? These need different records. Choose the relevant report and read its date basis, included statuses and currency before reaching a conclusion.
Separate orders and documents
Orders describe service, issued invoices record captured charges, and eligible credits record corrections. Cancellation, discounts and lifecycle state affect which records belong in a comparison.
Separate documents and collections
An unpaid invoice is not a collected payment. Cash receipts, verified gateway captures and staff-verified bank receipts each have evidence. Refunds also require their own records rather than an informal adjustment to a dashboard number.
Read costs carefully
Expenses describe incurred costs, not proof of payment. Inventory acquisition and recorded ingredient contribution describe specific operational facts. Neither is a complete profit calculation covering all liabilities, expenses and accounting adjustments.
Respect dates and currencies
Check the branch, timezone and period boundaries. Compare equivalent records and keep different currencies separate. A USD software subscription does not convert restaurant sales or alter their original currency.
Retain the source
Keep report filters and definitions with exported data. Reconcile disputed figures to source records. Ask an accountant to define statutory and management outputs instead of treating every operational CSV as final accounts.
