Where it usually breaks
And how to keep it from happening.
- A submission acknowledgement is treated as final confirmation. Agree exactly which provider response establishes the financial outcome.
- A timeout leads to another instruction with a new operation identity. Investigate the original reference and receipt first.
- A document is labeled Confirmation but remains unverified. Its title or evidence type cannot replace verification.
- An amount changes after approval. The earlier decision cannot authorize the changed instruction.
