Electronic Billing to Public Entities.
In order to be able to issue sales documents to public bodies, such as schools, town halls, parish councils, among others, companies are obliged to use electronic invoicing that allows it to be processed electronically, and the data must be presented in a format that can be transmitted directly between the issuer and the recipient and processed automatically.
How we implement XD in your business
The same honest, straightforward process, in every Algarve city where we work.
01
Visit and assessment
A colleague visits your business to assess the current situation — equipment, processes and real needs before proposing any solution.
02
Hardware preparation
If new equipment or adjustments to existing equipment are needed, we handle the on-site installation before moving on to the software.
03
Remote installation and configuration
XD is configured via remote access from our office, with your company's data and processes properly set up.
04
Team training
We train your team remotely; when clients prefer in-person training, we make the necessary visits — sometimes more than one.
XD support across the Algarve
We install, configure and train teams on XD for businesses across the Algarve — from electronic billing to ongoing technical support.
