Enterprise eInvoicing, before the deadline.
Casim works with enterprise teams to deliver fully compliant
eInvoicing infrastructure, integrated with your existing systems, before the mandate requires it.
One rate per entity, per month. No per-transaction fees, no volume surcharges, no surprise invoices as submission volumes grow. Budget with certainty from day one.


Your technical team works directly with Casim's senior engineers on system mapping, integration design, and PINT-AE / AS4 certification flows. Not a support ticket queue, a named contact.
Your developers get API sandbox access immediately, time to understand what's required, validate your current data against PINT-AE spec and run full integration tests before production go-live.


Casim manages your go-live readiness checklist. Certification testing, Peppol registration, FTA reporting setup, handled with your team, not delegated to you.
