Process PayPal transactions into AFAS as a separate, auditable technical posting process with a fixed external reference per transaction. Distinguish sales, fees, refunds and corrections, record the intent to write before sending and verify an unclear response before posting again. The financial configuration itself remains a decision for your finance team.
Start with a transaction type, not an amount
A positive or negative amount does not fully explain what happened. PayPal may report a payment, fee, refund, dispute or correction. For a technical integration, each supported type needs an explicit mapping to the AFAS route approved by finance. Unknown types must not silently disappear under ‘other’ merely because that makes the balance appear correct.
Retain the PayPal transaction ID, relevant order reference, currency, gross/net components and source timestamp. Minimise personal data and store only what matching, auditing and recovery need. This article does not provide tax or accounting advice; have qualified specialists determine accounts, journals and tax treatment.
Technical posting checklist
- Validate that the account and transaction belong to the correct workspace.
- Classify the supported transaction type and stop on unknown values.
- Link to an order by fixed identity, not just amount or customer name.
- Create an immutable posting snapshot with a deterministic reference.
- Record ‘sending started’ before the external write request leaves.
- Retain the confirmed AFAS result or mark the outcome as uncertain.
- Compare totals as a check, not as a replacement for transaction matching.
A workflow in Connect can carry out these steps once the business mapping has been configured and approved.
Fictional example: no response after POST
Fictional example: PayPal transaction PP-88021 is associated with order WB-610 through a retained order reference. The integration creates a snapshot and uses `PP-88021` in a deterministic AFAS identity. The connection drops during the write request. The local status remains ‘outcome uncertain’; a second posting is not sent immediately.
The recovery step searches AFAS for the exact deterministic identity. The record is present and the checked fields match. The first attempt is confirmed and the process continues without a duplicate. Another transaction has a new, unmapped type. It remains unposted in a work queue with its source values and requires finance review. This fictional example demonstrates technical control; it does not suggest which general ledger account to use.
Keep differences visible
| Outcome | Meaning | Next step |
|---|---|---|
| Posting confirmed | AFAS identity and content match | Include in reconciliation |
| Uncertain | No definitive response | Verify receipt |
| Unsupported type | No approved mapping | Let the finance owner decide |
| Identity conflict | Reference exists with different content | Do not overwrite; investigate |
| Unlinked order | Transaction exists; relationship is missing | Bounded matching or manual handling |
Let a staff member use Desk to see the order context and technical state without having to guess an accounting decision. For custom financial processes, an explicit process analysis matters more than additional automatic fallbacks.
Use a separate test set for each currency and transaction type. Have finance specify the expected AFAS result beforehand and compare it field by field after the technical run. Include a payment with a fee, a partial refund, a full refund, an unknown type and a repeated source record. Check that the repeated record finds the same identity and does not write again. Rounding differences should have a defined, controlled tolerance; a developer should not decide during an incident which difference is ‘probably fine’.
Also schedule a daily operational comparison and a broader monthly check. The first quickly flags new uncertain or unsupported transactions. The second examines completeness across period boundaries and compares source, intermediate and target totals according to the approved financial model. A technically successful posting must not automatically mean the period is financially reconciled. Technical success means the provider accepted the record; reconciliation establishes whether all intended records together represent the expected lifecycle.
Finally, assign an owner to each error category. Authentication and API reachability belong to technical operations, an unknown transaction type to finance and a missing order reference to e-commerce operations. One shared error queue slows recovery and encourages risky manual workarounds. The screen should therefore immediately show the correct team, the source information needed and the quick fix that must not be used.
