Is invoicing still eating your day?

You enter each order in your system and then again in the invoicing portal.
Customers ask for their invoice over WhatsApp or email and someone builds it by hand.
Payment receipts pile up and you are not sure which invoices have been paid.
You ran out of stamps mid-week or you are overpaying your provider.
Downloading issued and received invoices from the SAT is a manual job every month.
You move goods and every bill of lading is a fight with the SAT catalogs.

Electronic invoicing systems we have built

We have built invoicing for a stamp distributor, an accounting firm, a distributor with its own fleet, a platform for trucking companies and an online tax filing service. Each one solved a different problem with Mexico's tax authority.

Stamp distributor serving software integrators

Platforms: API · Web dashboard

The problem: It resold stamping to software companies and each customer depended on a single provider. Tracking and billing stamp consumption was manual.

What we built: A single API to stamp, cancel and query CFDI with three different PACs behind it, a compatibility layer for customers already integrated, stamp balances per account, limit alerts, an automatic monthly cutoff and bulk SAT downloads as a separate product.

Accounting and tax firm

Platforms: Web dashboard · Processing services · Self-invoicing portal

The problem: Its clients invoiced, sold and collected in a legacy system, and the firm processed SAT XML files almost by hand.

What we built: We maintain and extend its platform: CFDI 4.0 invoicing, payment receipts (including bulk and point-of-sale), a self-invoicing portal by ticket, daily bulk SAT downloads and an accounting module that builds journal entries, trial balance and VAT from the XML.

Wholesale distributor with its own fleet

Platforms: Web dashboard · API · Self-invoicing portal

The problem: It invoiced order by order, customers asked for invoices by message and every truckload needed its bill of lading.

What we built: Invoicing from quotes, delivery notes and orders (single or grouped), customer self-invoicing, a documented API, Carta Porte for income and transfer, payment receipts across invoices, addenda and stamp control. We also moved its stamping from one PAC to another.

Platform for trucking companies

Platforms: Web dashboard · Android and iOS app

The problem: Carriers invoiced their trips in a separate system and fought with SAT catalogs for each bill of lading.

What we built: When a trip ends, the invoice line is created automatically, with Carta Porte, payment receipts, credit notes, cancellation with acknowledgment, invoices in US dollars at the official exchange rate and stamp sales per company.

Online accounting and tax filing service

Platforms: Web dashboard · API · Download service

The problem: Its accountants had to gather each taxpayer's invoices and match them to bank statements before preparing the return.

What we built: We developed the automatic download of issued and received CFDI from the SAT, in a separate service so the main system never stalls, bank statement reconciliation against invoices and the tax return calculation per regime.

What custom electronic invoicing software does

In Mexico every invoice is a CFDI: an XML document that an authorized provider (a PAC) validates and stamps on behalf of the tax authority, the SAT. A generic portal lets you stamp. A custom system invoices from where you already work and handles what comes next: collecting, issuing payment receipts and reconciling.

CFDI 4.0 from your operation

The invoice comes from the order, delivery note, quote or finished trip, one by one or grouped, with the customer's tax data already validated.

Payment receipts and credit notes

Payment receipts for one or many invoices, credit notes, related CFDI and cancellations with acknowledgment, plus alerts for invoices about to fall due.

Bills of lading (Carta Porte)

Carta Porte is the complement Mexico requires to move goods by road. We tie it to the trip, with SAT catalogs preloaded so nobody looks up codes by hand.

Self-invoicing and API

Your customers create their own invoice from a folio or ticket in a portal, and other systems can stamp through a documented API.

Multiple PACs and stamp control

We connect one or several stamping providers, track the stamp balance per company or account and warn you before it runs out.

Bulk SAT downloads

Daily automatic download of issued and received CFDI with the taxpayer's e.firma, status checks and XML validation, ready for accounting.

Mexican e-invoicing glossary

The terms you will hear on the call, explained in plain English.

CFDI 4.0: Comprobante Fiscal Digital por Internet: the electronic invoice the SAT requires in Mexico. Version 4.0 validates the receiver's name, tax regime and postal code.
SAT: Servicio de Administración Tributaria, Mexico's tax authority. It defines the invoice format, the catalogs and the rules for cancellations.
PAC: Proveedor Autorizado de Certificación: a company authorized by the SAT to validate and stamp invoices. Your system connects to one or several.
Stamping: The digital seal a PAC adds so the invoice is valid for tax purposes. Each stamped document uses one stamp, which is why the balance matters.
Payment receipt: The CFDI issued when you collect an invoice sold on credit or in installments. It records how much, when and how you were paid.
Bulk download: The SAT service to download issued and received invoice XML in batches. It is automated with the taxpayer's e.firma (advanced electronic signature).

How we build your invoicing system

We review where your invoices come from today, which data is typed twice and what your accountant or large customers ask for, such as addenda or complements. That tells us which invoices to automate first.

We connect the PAC you already use or recommend one, load your certificates in a sandbox and stamp real cases before going live. If you need to change providers later, the system allows it without rewriting everything.

Frequently asked questions about electronic invoicing software

What is electronic invoicing software in Mexico?

It is the software that creates your CFDI, sends them to a PAC for stamping, delivers them to customers and tracks payments, cancellations and complements. A custom one does all of that from your own order, sales or trip system.

Do foreign companies need CFDI invoices?

A company with a Mexican tax registration that sells in Mexico must issue CFDI. If you operate through a Mexican subsidiary or move goods across Mexico, your invoicing system has to follow SAT rules, including Carta Porte for road freight.

Can you add invoicing to my current system?

Yes. We can add invoicing to an existing system or build a separate module with an API your system calls. We also migrate from one PAC to another without your users noticing.

Can you download my invoices from the SAT automatically?

Yes. We schedule a daily bulk download of issued and received CFDI with your e.firma, with retries when the SAT service fails and XML and PDF exports.

How much does custom electronic invoicing software cost?

It depends on how many document types you need, where invoices come from and the integrations involved. After the call we send a proposal with scope and price; on top of development, budget for your PAC's stamps.
