07 / System interfaces
A connection your team can understand.
A useful integration removes repeated entry while keeping disagreements visible. We identify which system leads for each fact and what staff should do when an update cannot be completed safely.
Agree the shared meaning
Customer identifiers, address fields, currencies and document references need explicit matching rules. We review real formats using synthetic examples and confirm provider documentation, account access and supported operations.
Handle uncertainty deliberately
Retries, duplicate protection and reconciliation are part of the scope. A timed-out request may already have reached the other system; a confident failed message can create duplicate work if it encourages another submission.
Leave useful support information
The integration exposes a proportionate error record and a safe route to resume work. Logs should explain the problem without routinely copying full personal records. The handover identifies assumptions, dependency owners and the checks needed when either system changes.
