CFDI 4.0 / SAT Compliance

How It Works

Invoicing Automation Workflow

01

Fiscal Configuration

We set up your RFC, CSD certificates, and fiscal regime in the invoicing system. SAT catalog mappings are configured for all your products and services.

02

System Integration

The invoicing engine is connected to your sales, POS, or ERP system via API. Transaction data flows automatically into invoice generation without manual entry.

03

Template & Rules Setup

Invoice templates are designed with your branding, and business rules for tax calculation, payment methods, and CFDI usage types are configured. Series and folio sequences are initialized.

04

Go-Live & Monitoring

After validation with SAT's test environment, we switch to production timbrado. Real-time monitoring tracks stamp success rates, and alerts flag any rejected invoices immediately.

What We Deliver

CFDI 4.0 Timbrado

Automated stamp (timbrado) generation through factura.com API, fully compliant with SAT's latest CFDI 4.0 requirements. Each invoice receives a valid fiscal digital seal in seconds.

CSD Certificate Management

Secure storage and automatic rotation of CSD digital certificates. Expiration alerts and renewal workflows ensure your invoicing never gets blocked by expired credentials.

SAT Catalog Integration

Full integration with SAT catalogs including ClaveUnidad and ClaveProductServ. Products and services are automatically mapped to the correct fiscal classification codes.

Batch Invoicing

Generate hundreds of invoices from receipt data in a single operation. Ideal for businesses that need to invoice large volumes of transactions at month-end or after events.

IVA Tax Breakdown

Automatic calculation and itemization of IVA (16%) and other applicable taxes per line item. Supports exempt, zero-rated, and standard tax scenarios as required by SAT.

Series & Folio Management

Organized invoice numbering with configurable series and sequential folios. Multiple series support different business units or locations under a single RFC.

XML & PDF Generation

Every invoice produces both the SAT-required XML and a professionally formatted PDF. PDFs include QR codes, fiscal stamps, and your company branding.

Use Cases

Invoicing Solutions

1

Event & Venue Billing

A venue processes hundreds of transactions per event and needs invoices generated for each. Batch invoicing creates all CFDIs from receipt data overnight, ready for customers the next morning.

2

Subscription Service Invoicing

A SaaS platform automatically generates monthly CFDI invoices for all active subscribers. The system handles different tax regimes, payment methods, and CFDI usage types per customer.

3

Multi-Location Retail

A retail chain with multiple locations uses series-based invoicing to track revenue per branch. Each store has its own folio series while sharing a single RFC and CSD certificate.

What CFDI 4.0 Automation Solves

CFDI 4.0 introduced stricter validation rules compared to previous versions. The recipient's RFC must match the tax regime registered with the SAT, the fiscal address postal code must be accurate, and the CFDI usage code must correspond to the correct taxpayer type (moral or physical person). Any mismatch causes the SAT timbrado to reject the invoice before it has legal validity. AISDC automates these validations in real time by querying SAT's official catalogs, normalizes your customer data before submitting to an authorized PAC, and manages the cancellation workflow with the SAT-required reasons. This eliminates manual entry mistakes and the costly reprocessing cycles that slow down your billing operations.

How We Integrate Your System into the Timbrado Process

AISDC is a software integrator, not a PAC. We connect your ERP, point-of-sale system, or e-commerce platform to a SAT-authorized PAC through custom-built adapters. We have developed integrations for systems such as SAP Business One, Odoo, proprietary platforms, and SQL or PostgreSQL databases. The connection works via REST or SOAP APIs depending on what the selected PAC exposes, and the stamped invoice (XML plus PDF) is returned to your system within seconds. We implement retry queues, timeout handling, and secure storage of the stamped XML to meet the five-year document retention requirement. The architecture is PAC-agnostic: if you switch timbrado providers in the future, the core integration remains in place without a full rebuild.

CFDI Complements: Carta Porte, Payment, and Payroll

The CFDI schema includes mandatory complements depending on the transaction type. The Carta Porte Complement is required for the transportation of goods by road, rail, or air within Mexico, and captures driver data, vehicle information, goods description, and origin-destination details using SAT catalog municipalities. The Payment Receipt Complement (REP) must be issued whenever payment is received on a date different from the invoice date. The Payroll Complement covers earnings, deductions, and IMSS contributions for individual employees. AISDC designs the data pipelines your operation needs to generate each complement type correctly, validating SAT catalogs before each timbrado request to prevent downstream rejections.

Operational Benefits of Automated SAT Compliance

Automating CFDI 4.0 invoicing reduces SAT rejections caused by manual data-entry errors such as invalid RFCs, incompatible tax regimes, or incorrect CFDI usage codes. Fewer rejections translate directly into less time spent by your administrative team correcting and resubmitting invoices. Digital stamping completes in seconds rather than minutes, speeding up end-of-shift reconciliations at point-of-sale and high-volume bulk invoicing runs at month close. Centralizing the entire flow through a single integration also simplifies internal audits: every stamped XML is stored with its UUID, timestamp, and cancellation status. AISDC delivers the system with structured logs and automated alerts for any timbrado SAT failure, so your team can respond immediately before an issue disrupts operations or creates a compliance gap.
