Invoices

In this documentation, we will explore how Ecart Pay enables businesses to efficiently manage their invoicing processes in compliance with the tax regulations of various countries. We will cover the key concepts surrounding invoices, their importance, the standard processes for their generation, and how Ecart Pay optimizes these workflows, including handling Digital Tax Receipts over the Internet (CFDI). Additionally, we will present the benefits and specific use cases of this solution.

What Are Invoices?

Invoices are legal documents that detail a commercial transaction between a seller and a buyer. They include information such as the total amount payable, the products or services provided, applicable taxes, and relevant dates.

In the context of Ecart Pay, invoices are digital documents generated and managed in compliance with each country’s tax regulations, ensuring legal and accounting validity.

Why Are Invoices Important?

Invoices are essential for recording commercial transactions, meeting tax obligations, and ensuring transparency in business operations. Additionally, they serve as vital tools for:

Tax Compliance: Avoiding penalties or fines by adhering to local laws.
Financial Control: Aiding in income and expense planning and recording.
Transparency: Providing clarity to both sellers and buyers regarding transaction details.

Typical Workflow for Generating an Invoice

Gather Basic Data: Collect customer information and transaction details.
Configure Taxes: Apply the relevant taxes as per local regulations.
Generate the Invoice: Create the electronic document in the required format (XML, PDF, etc.).
Validate and Register: Validate the document with the respective tax authorities, such as the SAT in Mexico.
Distribute: Send the invoice to the client and store it for audit and accounting purposes.

What Is CFDI and Its Relation to Invoices?

The CFDI (Comprobante Fiscal Digital por Internet) is a type of electronic invoice required in Mexico that complies with the tax standards set by the SAT (Tax Administration Service). An invoice becomes a CFDI through a certification process, ensuring its legal and fiscal validity.
