Pennylane integration for e-commerce sales invoices
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.

How Pennylane fits with myFulfillment
What is Pennylane?
Pennylane is a French financial-management and accounting platform. myFulfillment remains the operations system: it centralises orders regardless of their origin, then runs the logistics work around them. The connector steps in 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 against the source order. That is a precise boundary: customer sales reach accounting without turning myFulfillment into accounting software.

From myFulfillment to Pennylane
myFulfillment centralises orders before the accounting export, regardless of their origin. Pennylane therefore receives an invoice from an operational flow that has already been checked.

Accounting without re-entry
The integration sends an order to Pennylane after it is completed in myFulfillment and marked for export. An order still being processed remains in operations.
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.

When the Pennylane accounting handoff stops being manual
The connector fits 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.
- Explicit order selection before the accounting handoff
- Customer, VAT and payment references carried with the sale
- Invoice number and PDF attached to the source order
- Export starts after order completion and Pennylane export approval.
- The scope covers customer sales invoices. Supplier invoices and refunds remain in their respective workflows.
- The company and its accountant remain responsible for validating VAT rules and the accounting setup.

How our customers use Pennylane day-to-day
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.
Connect Pennylane to myFulfillment, step by step
- 1Open the Pennylane integration in myFulfillment and select "Connect to Pennylane".
- 2Approve the OAuth 2.0 connection with the Pennylane account that will receive the sales invoices.
- 3Configure VAT and payment mappings and, when needed, the analytical category for each store.
- 4Mark one completed order for export and send it as a first test.
- 5Check the invoice, customer and payment in Pennylane, then the number and PDF in the myFulfillment order history.
The connector covers customer sales invoices from completed orders. Supplier invoices and refunds follow their own workflows. The connection starts inside myFulfillment through OAuth 2.0.
Pennylane: frequently asked questions
OAuth setup, sales invoices, customers, VAT and payments: answers on the Pennylane integration.
Open the integration in myFulfillment and select "Connect to Pennylane". OAuth 2.0 handles authorisation 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 documented scope covers customer sales invoices. Supplier invoices, refunds and credit notes follow their respective workflows. This boundary avoids attributing an undocumented accounting process to the connector.
The connector looks for the customer before creating a record. It distinguishes a company from an individual and also handles guest orders. The result is a created or matched customer, preventing repeat exports from producing duplicates.
The rate is determined line by line from the billing country. The connector 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 recognised 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 connector 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 Tools screen, look up the record by its identifier to review the exchange. The help centre documents three synchronisation error families and how to handle them. Start from the displayed message before running the feed again, preserving one invoice for the order.
