Connect your ERP directly to the FIRS portal, or transmit manually if you don't run one. We handle the integration, testing, and ongoing transmission so you stay compliant without changing how your team works.
Whichever system you run today, we fit the integration to it rather than asking you to change platforms.
Direct API or webhook connection from Sage 200 Evolution, Business Central, Zoho Books or QuickBooks. Every invoice transmits to FIRS the moment it's posted — no manual step.
No ERP, or not ready to integrate yet? We set up a CSV, Excel or PDF upload workflow so you can stay compliant on your current timeline.
Every integration is tested against FIRS's sandbox before go-live, so the first invoice you transmit live is not the first one you're testing.
Real-time status on every invoice sent — accepted, pending, or rejected — so your finance team isn't guessing.
The same connectors also handle National Revenue Service e-invoicing requirements where they apply to your business.
FIRS specifications change. We monitor and update your integration so you're not left compliant today and broken next quarter.
Direct e-invoicing integration for Sage 200 Evolution — the platform behind most of our current FIRS/NRS rollouts.
See Sage 200 →Native connector built on Business Central's API layer for automatic invoice transmission.
See Business Central →Webhook-based transmission straight from Zoho Books, with no disruption to your existing invoicing workflow.
See Zoho Solutions →CSV and API-based transmission options for QuickBooks users, matched to your current invoicing volume.
See QuickBooks →FIRS is rolling out mandatory e-invoicing in phases, starting with large taxpayers and expanding to medium and small businesses. If you issue VAT invoices, it's worth planning for compliance rather than waiting for your phase to be enforced.
No. We support direct API/webhook integration from Sage 200 Evolution, Business Central, Zoho Books and QuickBooks, and we also support manual CSV, Excel or PDF upload for businesses without an ERP.
FIRS e-invoicing is the federal tax authority's invoice transmission requirement. NRS (National Revenue Service) e-invoicing integration follows the same underlying transmission standard for the systems we connect it to — we implement both from the same ERP connectors.
A standard ERP-connected integration typically takes 1–3 weeks from kickoff to live transmission, depending on how customized your invoice templates and chart of accounts are.
