Why this matters
The same vendors hit your feed hundreds of times a year. Bank rules teach Xero to pre-code recurring transactions once, so weekly reconciliation becomes clicking OK instead of re-deciding categories. Without rules, categorization stays manual forever and consistency drifts — the same vendor lands in three different accounts.
What "done" looks like
- Your top recurring vendors (rent, software, fuel, bank fees, processor fees) each have a rule
- The reconcile screen pre-fills most transactions; you confirm rather than categorize
- The same merchant always lands in the same account
How to do it
- Reconcile manually for two to four weeks first — you need to see what actually recurs.
- Create a rule from a real transaction: on the reconcile screen, choose to create a rule from the statement line.
- Set conditions on stable fields (payee contains "AWS") rather than exact amounts that change monthly.
- Assign the account, contact, and tax rate the rule should apply.
- Order rules sensibly — Xero applies the first matching rule, so put specific rules above broad ones.
Common mistakes
- Matching on exact amounts, so the rule breaks the first time a price changes
- Writing overly broad conditions that grab unrelated transactions into the wrong account
- Rule sprawl: never pruning, so stale rules silently miscode new activity
Real-world examples
- Bank rules are a standard bookkeeping-efficiency lever: practitioner guides commonly describe cutting weekly reconciliation to a fraction of the manual time once the top recurring merchants are covered.
- Xero's rules support any/all conditions on fields like payee and description, plus percentage splits across accounts — documented product behavior.
From a founder's point of view
Every rule is a decision you'll never make twice. The first month of bookkeeping is the real setup; after that, if a transaction type shows up a third time, it deserves a rule, not another minute of thought.
Rule of thumb
Seen it three times? Write a rule. Done means most weeks reconciliation is confirm-confirm-confirm, not decide-decide-decide.
