Security & Deployment
Your invoices stay where your invoices belong: on your server.
AcumenInvoice is designed around a single principle: financial documents are too sensitive to hand to a third-party cloud unless there is no alternative. There is an alternative — and this is it.
Data sovereignty
Every invoice, vendor name, line item, tax ID, and approval signature lives in a database you own, on a server you control, in the jurisdiction you choose.
Compliance by design
Data residency requirements (PIPEDA, provincial privacy laws, internal IT policies) are satisfied because the data never moves. No DPA negotiations, no sub-processor lists.
No vendor lock-in
You own the database, the documents, and the deployment. If you ever stop using AcumenInvoice, your data stays with you, in a standard PostgreSQL instance.
No per-invoice fees
Cloud SaaS pricing scales with your volume. AcumenInvoice is licensed per server. Process 100 invoices a month or 100,000 — same licence.
Operates offline
No external API calls during invoice processing. Suitable for air-gapped sites that pull updates manually on encrypted media.
Auditable code paths
Every validation rule, routing decision, and approval signature is recorded with cryptographic integrity. Auditors can trace any invoice end-to-end.
