Pennylane is the French invoicing and accounting platform. For companies billing in France, it is where an invoice stops being a PDF and becomes a compliant document the accountant can actually work with. Buildrhaus connects it to the rest of the cycle so it never has to be fed by hand.

Where it sits

Pennylane covers the Invoicing stage of the lead-to-care cycle, alongside Stripe. We reach for it when the billing entity is French and compliance matters: numbering rules, mandatory mentions, structured e-invoicing formats such as Factur-X are handled by the platform rather than reinvented in a homemade template. The integration question is upstream: most teams still create those invoices manually, retyping what sales already captured. That is the gap we close.

What Buildrhaus builds with Pennylane

• Invoices issued from deal eventsA signed proposal in PandaDoc or Qwilr, or a stage change in Attio, triggers the Pennylane invoice: customer, lines and terms come from the deal record.
• Compliance by constructionInvoices are born inside a platform built for French requirements, structured formats included, instead of being assembled in a word processor and hoped about.
• Payment status back in the CRMSettled and outstanding states are visible on the Attio record, so sales and finance read the same truth without a weekly export.
• A clean handoff to accountingThe same record flows from quote to ledger. Finance stops chasing sales for context, and closing the month stops being archaeology.

How we wire it

Pennylane exposes an API for customers, invoices and their statuses. Our pattern keeps the CRM as the trigger: an n8n workflow listens to Attio deal events, creates or updates the Pennylane invoice with mapped fields, then carries status changes back to the record, by event subscription where the account exposes it, by polling where it does not. Collections then continue on Stripe or Upflow, downstream of the same chain.

This connection is part of Revenue Engine Build, which takes the cycle end to end, from quote/CPQ through invoicing to collections. As a standalone unblock, it fits a one-week Signal Sprint.
