Because this is built to order, not an instant download, ECOSIRE configures it around your real tax setup before delivery. A typical build runs about one working week depending on how many municipalities you need and how clean your catalog/CNAE mapping is. We start by collecting your A1 certificate, CNPJ emitter details, tax regime, and target municipalities, build and validate the flow in the provider's sandbox/homologation environment, then go live only after sample emissions pass. We confirm a firm timeline with you before any payment-to-build commitment.

No. This is a custom integration that ECOSIRE builds, installs via OAuth, and supports for your specific store. We do not ship a generic one-click App Store app, because Brazilian tax emission depends on your certificate, regime, CNAE, and exact municipalities — those have to be configured per merchant to be correct and compliant.

Every build includes a post-launch support window for rejections, municipal schema quirks, and questions. Brazilian fiscal rules and municipal NFS-e schemas change, so we offer ongoing support and maintenance options — discussed and priced up front — to keep your emitter current as SEFAZ and city layouts evolve. You are never left to debug a rejected emission alone.

The integration handles NF-e for goods (ICMS) and municipal NFS-e for services (ISS), with coverage across 1,000+ municipalities. During the build we configure the specific cities where you are obligated to issue NFS-e, including their individual service codes and schema requirements. If you later expand into new municipalities, that can be added as a supported change.

Yes — you need a valid A1 digital certificate tied to your emitter CNPJ, and depending on the pipeline, an account with an authorized emission provider or direct SEFAZ access. We guide you through exactly what's required, configure the certificate and provider credentials securely into the integration, and validate everything in sandbox before issuing any live document.
