}'Yes. TaxBridge exposes one canonical invoice API your ERP calls when it posts a sales document. TaxBridge routes it to the right authority and returns the fiscal result to store against the document.
Sales orders and invoices fiscalised as they post.
AR invoices carry the fiscal number and QR.
Stock-driven billing stays compliant automatically.
Multi-tenant SaaS files per customer company.
Any app that emits a sales invoice can integrate.
Full logs and status make month-end reconciliation simple.
One canonical API for every authority and every company you serve.
Just register your business with Sum Cloud POS — it already files fiscal invoices to FBR, PRA, SRB and KPRA for you. No API, no development, nothing to connect or maintain. Start selling with compliant invoices out of the box.
