Frequently Asked Questions

How does the Electronic Invoicing API integrate with our existing software?

We deploy an asynchronous middleware microservice that ingests transactional records from your software or POS, computes the X.509 cryptographic signature, validates it with government tax servers, secures authorization codes (CUF/CUFD), and returns the official QR-encoded PDF ready for automated WhatsApp/email dispatch.

Can we connect WhatsApp to our ERP without risking phone number bans?

Yes. We use Meta's official WhatsApp Business Cloud API. As the authorized enterprise channel, there is zero risk of phone number blocking, allowing thousands of automated transaction alerts and multi-agent support.

What happens if our connection to government tax servers drops?

We implement robust offline contingency message queues (Redis / RabbitMQ). Sales transactions are securely logged locally and automatically retried and certified the second tax connectivity is restored.

How long does an API or ERP integration project take?

Focused integrations (like WhatsApp Cloud API or dynamic QR payments) take 1 to 2 weeks. Complex fiscal invoicing modules or full ERP data synchronizations take 3 to 5 weeks including certified staging testing.
