Finance integrations fail when two systems both believe they own the same number.
Decision boundary
Finance integrations fail when two systems both believe they own the same number.
Do not begin with a screen list or a vendor promise. Define the operating decision, the data that proves it and the person responsible for exceptions.
Requirements to confirm
- Choose the accounting owner for customer, invoice and payment records
- Define posting timing, reversals and reconciliation exceptions
- Test currency, tax and rounding rules with real examples
Common mistake
Treating a workflow as a set of fields usually creates a system that looks complete but cannot explain ownership, exceptions or acceptance. Keep each rule testable with representative records and real job roles.
How to start
Start with one bounded workflow, document assumptions and acceptance evidence, then expand after the first milestone is operated safely. See the related service and illustrative scope。
