Integrations / Payments / Stripe
Stripe integration
The pay button
takes an afternoon.
Then the work starts.
Which payment belongs to which order? Why does the payout in the bank account not match revenue? Who books the fees and the refunds? That is the part I automate.
What Stripe gives you to work with
API
Everything programmable
Payments, customers, subscriptions and invoices — with idempotency keys, so a retried call never charges twice.
Webhooks
Stripe tells you
Payment succeeded, invoice paid, refund, dispute, payout. Every event is signed, so nobody can forge one.
Balance
Gross, fee, net
For every movement Stripe reports gross amount, fee and net amount — the basis for reconciliation to the cent.
Payouts
The bank line explained
Every bank transfer from Stripe can be traced back to the individual payments inside it. That is how the bank statement finally adds up.
What companies use it for
- Payment → order → warehouse: the payment arrives, the order is released, the invoice is created and picking is triggered — without anyone checking.
- Stripe into ERP or accounting: revenue, fees and refunds as clean journal entries, exported in the format your accounting reads.
- Payout reconciliation: the lump-sum bank transfer is split into its individual payments and matched to invoices automatically.
- Subscriptions: failed charges, dunning and access suspension as one continuous flow.
- Disputes: on a chargeback, the order, the delivery proof and the correspondence are bundled and ready.
The mistake almost every integration makes
Many shops mark an order as paid the moment the customer lands back on the “thank you” page. Convenient — and wrong. The browser coming back proves nothing: the customer can close the window, the connection can drop, and anyone who knows the thank-you URL can open it directly. Paid is only what Stripe has confirmed with a signed webhook.
I know this point from running my own e-commerce operation with retail and wholesale customers. So I build every payment integration to the same rule: the webhook is the only truth, its signature is verified, every event is processed exactly once — and when an expected event does not arrive, that gets noticed.
Security
Card data never touches your systems. It is entered directly at Stripe, which as a certified payment provider also handles strong customer authentication (3-D Secure). On your side there are only references and amounts. Keys are stored separately and can be rotated.
How I go about it
01
Read what the system offers
Which data lives where, who needs it when, and which route the system genuinely provides. The output is a one-page interface sheet, not a concept paper.
02
Prototype on real data
Within days the first real record travels from A to B. Only then do the actual problems show up: formats, edge cases, permissions.
03
Run it properly
On monitored servers, with retries, a log and explicit failure handling. Not a script on a forgotten office PC.
04
Let AI watch it
A delivery that does not arrive, a format that changes, a total that drifts — the integration reports it before accounting or the warehouse notices.
Questions I get asked
We already have Stripe in our shop — what does an integration add?
The shop plugin takes the money. The integration makes everything after that happen by itself: release the order, create the invoice, book the fees, reconcile the payout, carry the refund into the ERP.
Can Stripe data go into our accounting software?
Yes. Balance transactions become journal entries with revenue, fee and payout, exported in the format your accounting reads. Which accounts are used is something you settle with your accountant.
Can PayPal and bank transfers run in the same flow?
Yes — that is the normal case. All payment routes end in the same order status and the same reconciliation. See the PayPal integration page.
Other integrations
ERP
SAP
Deliveries, stock, advice notes and master data out of SAP — via IDoc, BAPI, OData or a plain file export.
Freight forwarding
CarLo
Orders, tours and shipment status out of the CarLo transport management system — into warehouse, customer portal and reporting.
Payments
PayPal
PayPal transactions matched to the order and booked automatically — instead of a CSV export at month end.

How many hours a month
does reconciliation
cost you?
If someone compares Stripe exports with invoices at month end, that job can be removed. Show me your current flow.
