}'Your company is reviewed and approved for production before live keys are issued.
Store the real credentials each authority issued you — encrypted at rest, never returned to your app.
Configure the companies and branches whose invoices you will file.
Enable each authority you subscribed to for the production environment.
Generate a tbk_live_ key and point your software at production.
Watch usage, logs and the authority health monitor. Support is available on every plan.
TaxBridge cannot guarantee automatic approval where an authority requires its own registration or clearance. Some authorities must issue you credentials or approve your merchant before live submissions succeed. TaxBridge makes the software side fast; the authority-side requirements still apply.
Talk to an integration expert about production credentials and timelines.
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.
