# VeriFactu integration

> Invoicing software in Spain has to meet the invoicing systems regulation. We adapt your own software to VeriFactu or build a new one compliant out of the box, together with e-invoicing and SEPA direct debits.

## What's included

- VeriFactu adaptation for in-house invoicing software.
- Custom multi-company invoicing and accounting software.
- E-invoicing in Facturae format.
- SEPA direct debits.
- E-invoices and bulk sends generated in the background.
- Sales, purchases, inventory and banking in one place.

## Already in production

Our invoicing and accounting platform runs several companies at once and is compliant with Spanish tax rules out of the box:

- VeriFactu, Facturae and SEPA direct debits built in.
- Sales, purchases, inventory and banking in a single platform.
- E-invoices and bulk sends generated in the background.

## How we work

- A clear estimate before we start, no surprises.
- Phased deliveries: you see progress early and always know where the project stands.
- Our own code, documented and reviewed: any team can pick it up.
- Deployment, monitoring and support once it's live.

## Common questions

### Can you adapt the invoicing software we use to VeriFactu?

If it's your own software, yes: we review how it issues and stores invoices and adapt it. If you use a commercial product, adapting it is up to its vendor.

### What is your invoicing platform built with?

Python (FastAPI), Celery, Redis and MySQL. Heavy sends run in the background so the app stays responsive.

### Do you also handle SII?

Yes. If your company is in the SII, we connect the software to the AEAT for invoice filings and rejection handling.

## Tell us about your project

We reply within 24-48 business hours with a proposal and an estimate, no strings attached.
