PayPal Payments Sync

The pain

PayPal money arrives fast and lands in your accounts badly. A customer pays a 480.00 invoice, PayPal takes its cut, and 465.12 shows up in a payout three days later bundled with forty other transactions. Someone in finance now has to work backwards from a single bank line to a list of invoices, find the fee, decide which G/L account it belongs to, and repeat that every settlement cycle.

Then the edge cases start. A partial refund on an order that was already invoiced. A dispute that holds funds for six weeks and either resolves or becomes a chargeback with its own fee. A payment in a currency your company does not use, converted by PayPal at a rate that is not your SAP exchange rate. A duplicate capture on a retried checkout. Multi-currency, multi-account, multiple web stores feeding one company database.

Without automation, the pattern is always the same: A/R Invoices sit open in SAP Business One long after the customer paid, the PayPal balance never ties to the general ledger, and month-end closes with a suspense account nobody wants to explain.

What ECOSIRE builds

We build a SAP Business One add-on that treats PayPal as a real payment channel with its own clearing account, its own fees, and its own reconciliation — not as a spreadsheet exercise.

Transaction ingestion

A scheduled service authenticates against PayPal's REST APIs using your merchant credentials and pulls transactions on the interval you set. Captures, authorisations, refunds, reversals, disputes, chargebacks, fees and payouts are staged in User-Defined Tables with the PayPal transaction ID as the idempotency key, so a re-run, a network failure or an overlapping poll window can never double-post. Every raw payload is retained for audit against PayPal's own reporting.

Matching to Sales Orders and A/R Invoices

The matching layer resolves each capture to the right SAP document using the reference data you actually pass at checkout — invoice number, custom ID, order number, or a UDF you nominate on the Sales Order or A/R Invoice. Where the reference is missing, a configurable fallback matches on Business Partner e-mail against OCRD/OCPR plus amount and date tolerance. Anything the engine cannot resolve with confidence is queued for human review rather than guessed at — an unmatched payment is a question, not a posting.

Incoming Payments, fees and clearing

Matched captures create Incoming Payments (ORCT) against the target A/R Invoice through the DI API or Service Layer, banked to a dedicated PayPal clearing G/L account rather than to your operating bank. The processing fee is posted in the same transaction to the fee expense account you nominate, so the invoice closes at gross and the fee lands where the P&L expects it. Partial captures, over-payments and short-payments follow the rules you set: leave the balance open, post the difference to an under/over-payment account, or hold for review.

Where your business takes money before invoicing, the add-on can post the capture as a payment on account against the Business Partner instead, ready to be applied when the A/R Invoice is raised.

Refunds, disputes and chargebacks

A PayPal refund creates the corresponding A/R Credit Memo or Outgoing Payment path you configure, reversing the correct portion of the original document and posting any refunded or retained fee. Disputes are tracked as their own state on the SAP-side record: a UDF on the A/R Invoice and a UDT row carry the dispute status, the held amount and the case reference, so credit control can see that funds are contested without hunting through the PayPal dashboard. When a dispute becomes a chargeback, the loss and the chargeback fee post to the accounts you nominate.

Settlement and bank reconciliation

This is the part that saves the month-end. Each PayPal payout is imported as a settlement batch: the add-on assembles the individual captures, refunds and fees that make up the payout, posts the transfer from the PayPal clearing account to the bank G/L account, and produces a batch document whose total ties to the single line on your bank statement. Your accountant reconciles one line, and the detail behind it is one click away in SAP rather than in a downloaded CSV.

Multi-currency and multi-account

Multi-currency is handled explicitly. The add-on records the transaction currency, the PayPal conversion where PayPal converted, and the SAP exchange rate applied at posting, and posts realised gain or loss to the account you nominate. Multiple PayPal merchant accounts — separate stores, separate legal entities, separate currencies — are supported as distinct sources, each with its own clearing account, fee account and Business Partner defaults.

Monitoring

An operations screen shows sync status per source, unmatched transactions, failed postings with the SAP error text, disputes in flight, and settlement batches awaiting reconciliation. Failures alert rather than fail silently, because a payment integration that stops quietly is worse than one that never ran.

Who it is for

Companies running SAP Business One 10.0 behind a web store, marketplace or invoice-payment link where PayPal is a real share of receipts, and where finance is currently reconciling settlements by hand. Also service businesses that take deposits through PayPal and need those funds visible against the customer before the invoice exists.

How delivery works

1. Scoping call. We map your PayPal accounts, currencies, checkout reference data, chart of accounts, fee treatment, refund policy and which SAP documents payments must land against. 2. Fixed quote. A written scope covering sources, matching rules, posting behaviour for each transaction type, and a fixed price. 3. Build. We develop against your test company database and your PayPal sandbox, so posting logic is proven on your chart of accounts before any real money moves. 4. Install in test. Full cycle rehearsal in your test company: capture, fee, partial refund, dispute, payout reconciliation. 5. Install in production. Live credentials, controlled first sync, and a supervised first settlement close with your finance team. 6. Support window. A defined post-go-live period covering defects, matching-rule tuning and PayPal API changes within the agreed scope.

Lead time is typically one working week from signed quote. This is built to order — nothing is downloadable, there is no trial, and we do not claim any certification or partnership with PayPal or SAP. What you receive is an integration built for your accounts, your currencies and your chart of accounts.
