The Pennylane integration turns completed myFulfillment orders into sales invoices without a file export. Customer details, country-level VAT and payment references travel with the order. The invoice number and PDF return to its history, giving operations teams and accountants a traceable handoff.

Pennylane is a French financial-management and accounting platform. myFulfillment remains the operations system: it centralizes orders regardless of their origin, then manages the related logistics work. The integration takes over after a sale is complete and approved for accounting export. It prepares the customer, lines, VAT, and payment references, creates the Pennylane sales invoice, and stores its number and PDF with the source order. This creates a clear boundary: customer sales reach accounting without turning myFulfillment into accounting software.
All completed orders in myFulfillment.
Controls the export and prepares customer data, line items, VAT and payments for Pennylane.
Sales invoices created in Pennylane, with payments matched by reference.
myFulfillment centralizes orders before the accounting export, regardless of their origin. Pennylane therefore receives an invoice from an operational flow that has already been checked.
The integration sends an order to Pennylane after it is completed in myFulfillment and marked for export. An order still being processed remains in the operational flow.
Completed in myFulfillment and marked for export
See the featuremyFulfillment creates the matching sales invoice in Pennylane. The invoice number returns to the order history and the PDF is archived; a successful invoice is never exported twice.

See the featureBefore creating the invoice, the Pennylane integration looks up the customer, then creates or matches the customer record. It distinguishes companies from individuals and also handles guest orders.

The integration is a good fit when the friction lies between a completed e-commerce order and its customer sales invoice. It removes re-entry while keeping operations and accounting responsibilities clearly separated.

See how the Pennylane integration fits into your operations
The business owner and accountant see the same handoff from different angles. One wants to retire manual exports; the other needs clean invoices, supporting documents and references that make the file easy to review.
The team completes the orders that are ready for accounting. The integration sends those marked for Pennylane and leaves the rest in the operational workflow.
Each invoice carries the matched customer, lines, VAT by country and payment reference. Its number and PDF remain available from the original order.
An optional analytical category can represent each store, keeping sales separable in Pennylane without creating a separate accounting entity for each channel.
The integration covers customer sales invoices from completed orders. Supplier invoices and refunds follow their own workflows. The connection starts inside myFulfillment through OAuth 2.0.
Open the integration in myFulfillment and select "Connect to Pennylane". OAuth 2.0 handles authorization and the token refreshes automatically. Configure VAT and payment mappings, then test one completed order before enabling the feed.
Any order completed in myFulfillment can become a Pennylane invoice, regardless of its original sales channel. It is sent when marked for export; work still in progress remains in the operational flow.
The integration handles customer sales invoices. Supplier invoices, refunds, and credit notes follow their respective workflows, outside the integration.
The integration looks for the customer before creating a record. It distinguishes a company from an individual and also handles guest orders. The customer record is created or matched to an existing record, preventing repeat exports from producing duplicates.
The rate is determined line by line from the billing country. The integration adds an adjustment when rounding creates a difference and uses the documented fallback for a VAT-exempt sale. Your accounting team remains responsible for validating the tax rules.
For a bank transfer, matching uses the order number. For Stripe and GoCardless, it uses the transaction identifier. Those references travel with the invoice so the payment can be recognized without a manual search.
Pennylane holds a customer invoice with its lines, VAT and payment reference. In myFulfillment, the order history retains the processing status, Pennylane invoice number and archived PDF, linking the accounting document to the source order.
Yes. An optional analytical category can be associated with each store within one Pennylane entity. It makes sales filterable by store without changing the customer sales-invoice scope.
The integration sends clean sales data to Pennylane; it does not replace an assessment of your e-invoicing regime. Read the e-commerce guide and use the compliance test to identify your obligations, then validate the setup with your accountant.
In the diagnostics screen, look up the record by its identifier to review the exchange. The help center documents three synchronization error families and how to handle them. Start from the displayed message before running the feed again, preserving one invoice for the order.
