Veterinary billing and invoicing without the busywork.
OpenVPM supports itemized estimates and invoices, balance history, and recorded payments. Supported treatment and encounter workflows can add line items. Client online card payment requires completed Stripe Connect setup, and card-present terminal payments are not integrated.
Workspace access is immediate. Live clinic use starts as a guided pilot alongside the current PIMS. See current fit and rollout limits.
Billing & Invoicing
Build itemized invoices manually or from supported treatment and encounter workflows. Estimates convert to invoices, and OpenVPM tracks balances and recorded payments.
- Itemized invoices from manual entry or supported workflows
- Approved estimates convert to invoices
- Payment tracking with account balance history
- Revenue and payment reporting
Open source
The whole PIMS is AGPLv3. Read it, run it, shape it. This module is included, never gated.

Common questions
Do charges get added automatically?
Supported treatment-template and encounter workflows can add line items. Clinics still review every invoice and add anything outside those workflows manually.
Can estimates become invoices?
Yes. Build and approve an estimate, then convert it without re-entering its line items.
Does OpenVPM track payments and balances?
Yes. OpenVPM tracks recorded payments and account balances. Client online card payment requires Stripe Connect setup; card-present terminals are not integrated.
Are there per-user fees?
No. Self-hosting is free under the AGPLv3 license. OpenVPM Cloud is priced per location with unlimited staff, no per-user fees.
