Send your invoices to Pennylane
Every invoice and credit note finalized in Joinways goes to Pennylane with its PDF, and you send your vendors' invoices there too.
Aggiornato il
Pennylane is not an invoicing channel: it is your accounting. Once connected, every invoice and credit note finalized in Joinways goes to Pennylane automatically, with its PDF. Your accountant has nothing left to retype.
On demand, Pennylane also receives the invoices your vendors upload from their vendor link.
What you'll learn
- Connect Pennylane by authorizing Joinways in Pennylane.
- Use an API token instead, if needed.
- Know which invoices are sent and follow the sending.
- Send your vendors' invoices to Pennylane.
Prerequisites
- Be an owner or admin of the Joinways workspace.
- Have access, in Pennylane, to the company to connect. For the API token route, you also need access to its developer settings.
1. Connect Pennylane
- In Joinways, open "Settings" > "Integrations", "Invoicing" tab, then click the "Pennylane" card.
- Click "Continue to Pennylane".
- In Pennylane, pick the company and allow access to customers, customer invoices and attachments. You come back to Joinways and "Pennylane connected" shows. There is nothing to copy.
2. Or use an API token
- In the "Connect Pennylane" window, click "Use an API token instead".
- In Pennylane, open Settings, Connectivity, Developers, then create an API token with these permissions, read and write: customer invoices, customers, attachments. Pennylane shows it only once.
- Paste the token into "Pennylane API token", then click "Connect". Joinways checks the token and its permissions before saving it.

The token is stored encrypted and never shown again.
3. Which invoices are sent
- Invoices and credit notes issued by Joinways, in the venue's series.
- Stripe invoices and their credit notes.
Invoices issued on Qonto or in QuickBooks stay in those tools and are not sent to Pennylane. Only invoices finalized after the connection are sent.
Joinways creates the customer in Pennylane if it doesn't exist yet, then imports the invoice and its PDF. For a company customer whose SIREN is known, the invoice is imported as an e-invoice.
Tip: a venue whose invoices are issued in another software ("Invoicing software", in the venue's "Proposals & invoicing") no longer issues any invoice in Joinways, whatever channel is connected.
4. Follow the sending
Click the card's gear to open "Pennylane Settings".
- "Automatic sync": on by default, it sends every finalized invoice and credit note. Turned off, nothing is sent anymore.
- The "Synced", "Pending" and "Errors" counters give the state of the sending.
A failed sending never blocks the invoice in Joinways: it is issued normally.
Send your vendors' invoices
Your vendors (caterer, DJ, florist) upload their monthly invoice from their vendor link. You then send it to Pennylane without downloading it again. It is imported as a supplier invoice, with its PDF, linked to the vendor.
- Open an event of that month, "BEO" tab, "Vendors" section.
- On the vendor's row, click the "Invoice received" badge, or open the "…" menu, then "Invoicing for the month".
- On the invoice, click "Send to Pennylane". The label turns to "Sent to Pennylane".
- Before sending, pick the invoice's VAT rate: 20, 10, 5.5, 2.1 or 0%.
The paid status is read again each time the month is opened: an invoice settled in Pennylane shows "Sent to Pennylane, paid there". Each invoice goes to each tool only once.
Important: the first time, Pennylane does not allow supplier invoices yet, since they are not requested at connection. Click "Allow in Pennylane" and accept in Pennylane. You need the right to connect Pennylane (owner or admin).
