Integrations
Connect BillMore with other tools
Besides the REST API, BillMore offers ready-made integrations for no-code automation and online payments - without building them yourself.
No-code automation
BillMore in Make.com
No code needed: the official BillMore node for Make.com lets you connect BillMore with hundreds of other apps and build automations visually.
Possible use cases
Shop system
A new purchase in your online shop automatically creates the invoice and sends it.
CRM synchronization
New contacts from your CRM are created in BillMore automatically - ready for invoicing.
Documents & workflows
New invoices in BillMore can trigger further actions in connected apps.
The BillMore node is officially available in the Make.com app directory. An integration for n8n is planned.
Payment integration
Mollie payment links
Once an invoice is finalized, you can generate a Mollie payment link in BillMore. Send the link directly to your customer. They can pay the invoice online, easily and securely, without entering an IBAN.
How the payment link works
Prerequisite: an active Mollie account, connected in your BillMore settings under Extensions.
Tax advisor integration
DATEV integration
With the DATEV Rechnungsdatenservice 1.0 integration, you can send incoming and outgoing invoices together with structured invoice data from BillMore straight to DATEV Unternehmen online.
