digital invoices

since last March 31, 2004 have been nearly five years since its operation nationwide.

The initiative of the Electronic Invoice

A living example is what has happened with the primary sector that previously had been using the model of

AUTO BILLING facility has now been repealed and are forced to use a PACFD authorized by the SAT for Electronic Invoice.

This type of process to make the AUTO CHECK PACFD is contemplated that the entity responsible for the administration of the folios, the stamping of digital invoices from both the as the primary service provider.

should generate 2 impressions of such receipt to be signed by the producer and the deduction can be made of this proof of the flat tax.

Another example can be seen was that of models of self printers who had the facility to check in on their own to meet the requirements of Art. CFF 28 and 29, which struck down where they gave the option of returning to pre-printed forms (Print Authorized SAT) and / or use electronic billing.

self The universe is about 1,200 printing companies that were in this model where 80% of them migrated to a CFD solution.

market alternatives in terms of electronic invoice solutions focus on 3 models:

Sale system (software)

Revenue Service (Outsourcing)

Develop your application

Where companies are using to service providers for the short time of implementation. Since most companies believe that their critical sales information can be known by others.

But as has been the acceptance of electronic bill now?

Different industries have taken the issue of electronic bill allowing them to make big profits:

per print cost reduction, messaging, backup, search.

Process Automation.
Times.
However, there are some fine points that have not been considered by some companies that are doing their issuance and / or reception without meeting the basic rules such as:

If it generates electronic invoice must be for all customers (only financial statements that dictate what can be done.)

The folio of bills is provided by the SAT in all series and must begin with # 1.

must report monthly to all CFD existing or canceled.

must use the Digital Certificate Seal not the electronic signature.

If you hire a service a third, it must be certified by the SAT.
This does not relieve them of taking an accounting system.

On the other hand we found many companies receiving CFD do not know how to validate that the above is that made by the issuer properly.

Another major points that have been detected in models of integration of electronic invoices with business partners is that they are using intermediaries that are affecting that if they wish to receive a direct and electronic bill forcing them to hire a means of connecting with them, coming to repeal every invoice sent or received costs ranging from 0.78 cents to 2 dollars per invoice.

what is represented by information transfer costs.

The healthiest for this type of exchange is to use secure communication protocols securely over the Internet as AS1, AS2, AS3, AS3, Web_Service, S / FTP, http, http / s.
