Frequently Asked Questions

Which countries and tax regulatory frameworks are currently supported?

We fully support the online electronic invoicing system of SIAT (Bolivia), DTE and electronic receipts for SII (Chile), and the electronic invoice system SIFEN (Paraguay). Our microservices are continuously updated with regulatory tax amendments.

Do we need to replace our current software or point of sale (POS) system?

No. We deploy a lightweight, high-performance middleware API that bridges directly into your database or POS. When your cash register records a transaction, our API handles cryptographic signing, tax validation, and QR generation with zero disruption to daily workflows.

What happens if internet connectivity fails during checkout?

The system automatically falls back to offline contingency mode as mandated by tax regulations, instantly printing or sharing the receipt with the client and batch-syncing with tax servers upon reconnection.

Do we receive the integration source code?

Yes. In accordance with our core principle of technological sovereignty, we deliver the complete repository, source code, and architectural documentation for the connectors developed for your enterprise.
