Start with the built-in checks
Line items against totals, date formats, duplicate numbers and more.
Add your own rules
Earliest and latest dates, allowed suppliers, amount limits.
Anything that fails waits
The item goes to the review queue with the reason beside the value.
Most errors in intake are not misread characters but values that do not agree with each other: a total that does not match its lines, a start date before a signing date, a customer name spelled three ways.
Checks catch those before a person has to. Rules are written in plain fields, without code, and each one shows how many items it stopped in the last month.
