Overview - e-Invoicing

What is Electronic Invoicing?

The Mexico Tax Authority has introduced Comprobante Fiscal Digital por Internet (CFDI) Electronic-invoicing to standardise the way business-to-business (B2B) invoices are reported to SAT (Servicio de Administración Tributaria). This ensures that all invoices are submitted to the SAT portal in a common format.

Is Electronic-Invoicing necessary for your business?

The SAT has mandated Electronic-Invoicing for all businesses from 2014.

How does Electronic Invoicing work in Zoho Invoice?

Electronic-Invoicing in Zoho Invoice is a simple and hassle-free process. Zoho Invoice has partnered with an authorized certification provider - Proveedores Autorizados de Certificación (PAC´S). Zoho Invoice helps you create invoices in the XML and PDF file format by including all the mandatory fields mentioned by SAT.

These invoices can be stamped to SAT at the click of a button. The SAT will then send a unique UUID number or Folio Fiscal to identify this invoice, along with a QR code. You can include these in your invoice and send it to customers. Zoho Invoice also provides you with the option to cancel CFDI if needed.

This guide will help you understand how you can use Zoho Invoice to stay compliant with Electronic-Invoicing.

Stamped	The transaction was stamped to the SAT successfully, and a QR code and UUID has been generated for it.
Stamping Initiated	The transactions are being stamped as part of a bulk stamp action.

The Electronic-Invoicing system requires the following transactions to be stamped to the SAT. A UUID will have to be generated for each of these transactions:

• Invoices
• Credit Notes

Create Invoices

The SAT had mandated a set of fields that are required for an Electronic-Invoice. Some of these must be entered while creating new invoices. The other mandatory fields, will be auto populated if you’ve already entered them in Zoho Invoice (e.g. Customers Name or Items details )

Here’s a list of the mandatory fields across all the applicable modules for Electronic Invoicing:

Module	Mandatory Fields
Items Creation	SAT item code, SAT unit code
Customers Creation	Tax regime, Business legal name
Invoice Creation	CFDI reference type, CFDI usage
Record Payment for Invoice	Payment Mode
Payment Received	Payment Mode
Recurring Invoice	CFDI and Payment Mode
Credit Note	CFDI reference type, CFDI usage

The other mandatory fields depends upon the supplier’s business.

Stamp Invoices to PAC’S

Invoices in Zoho Invoice can be stamped to the Electronic-Invoicing portal with the click of a button. If you have enabled transaction approval, then the invoices must be approved before you can stamp them to PAC’S. If you’ve set up multi-level approval, then you can stamp invoices only after they’ve been approved by the final approver.

Here’s how you can stamp invoices to the PAC’S:

• Navigate to the Invoices module.
• Select the invoice that you want to stamp to the portal.
• Click the Stamp Invoice button.

If the invoice is stamped to the PAC’S successfully, then a UUID and QR Code will be generated by the PAC’S. This UUID is unique to each invoice and will be used to identify it for the entire financial year.

Once the invoice is stamped, you can download the CFDI in the PDF or XML format. The stamped invoice will also have the SAT Digital Stamp, CFDI Digital Seal and Original String details at the bottom of the invoice PDF.

Bulk Stamp

You can save time and stamp multiple invoices to the SAT at once, using bulk actions in Zoho Invoice. Here’s how:

• Navigate to the Invoices module.
• Click All Invoices above the list of invoices.
• Select Ready-to-be Stamped for Electronic-Invoicing from the list of filters.
• Select the invoices that you want to stamp to the portal.
• Click the More button on the top.
• Select Stamp Invoices.

Now, stamping the selected invoices to the SAT will be initiated. When successful, a QR code and UUID will be generated for all of them.

If any of these invoices failed to be stamped to the SAT, you will be notified of it and an error summary will be sent to your (the user who initiates the stamp) email address that’s registered in Zoho Invoice.

Cancel Electronic Invoices

You cancel an Electronic Invoice if you’ve entered any incorrect values or for any other reason.

Cancelling an electronic invoice within 72 hours

If you cancel an Electronic-Invoice in Zoho Invoice within the first 72 hours of generating an UUID for it, then it will be cancelled in the UUID also automatically.

To cancel an Electronic-Invoice:

• Navigate to the Invoices module.
• Click the Electronic-Invoice that you want to cancel.
• Click the Cancel CFDI button.
• Select the reason for cancelling the CFDI.
• Click Cancel CFDI.

Cancelling an electronic invoice after 72 hours

After 72 hours of stamping an invoice to the SAT successfully, the UUID generated will no longer be available in the SAT. So cancelling in Zoho Invoice will not cancel it in the SAT automatically.

Instead, you can mark the Electronic-Invoice in Zoho Invoice as cancelled, and then go to the SAT portal to cancel the UUID manually.

Once an Electronic-Invoice has been cancelled/marked as cancelled in Zoho Invoice, its status will change to Void. If needed, you can clone this invoice, make the necessary changes, and then stamp this new invoice to SAT.
