ERP for US companies operating in Mexico

Picking an ERP for your Mexican entity — the part nobody warns you about

Your US ERP almost certainly cannot issue a legal Mexican invoice. And the decision that determines whether a system can is not the brand — it is the edition and hosting tier you buy. Get that wrong and the fix is expensive.

The core problem

Mexican compliance is not a localization pack you switch on

In Mexico an ERP has to sign every invoice with your certificate, send it to an authorized provider for validation, and store the returned XML. On top of that it must produce a monthly third-party transaction report and electronic accounting files in government formats.

Most US-centric systems either cannot do this at all, or do it through a third-party add-on you will maintain forever. And among the systems that do support Mexico, the capability frequently sits in a higher-priced edition than the one you were quoted.

The question that decides your platform

Do you invoice large retail chains or automotive OEMs? They require an addenda — their own XML block inside your invoice. Supporting one means installing custom code, which several cloud tiers flatly do not allow. Ask this before you sign, not after.

How to choose

Four questions, in this order

1. Can it stamp natively?

If invoicing needs a third-party module, that is a permanent maintenance line item, not a one-time cost.

2. Does it support your provider?

Most systems integrate a short list of authorized providers. If yours is not on it, you are writing a connector.

3. Can you install custom code?

Addendas and industry-specific complements are modules. Some hosting tiers do not accept any.

4. What is the total, not the license?

License is the small number. Implementation, catalog mapping and payroll add-ons are the real budget.

We implement Odoo and SAP, so we have no reason to push you toward either. The detailed edition-by-edition comparison lives on our Odoo versions guide.

What it costs

Published pricing, in pesos, with a go-live date

We publish our implementation packages rather than making you sit through a discovery call to hear a number. For a US company standing up a Mexican entity, the middle package is usually the fit: it includes full CFDI 4.0 invoicing, the payment complement, the third-party report and electronic accounting.

Starter — MXN $29,900

Sales, purchasing and inventory for one business line. 2-3 weeks. No tax module.

Empresa MX — MXN $89,000

Everything above plus CFDI 4.0 with your provider, payment complement, DIOT and electronic accounting. 4-6 weeks.

Comercio MX — MXN $139,000

Adds point of sale with global invoicing and e-commerce. 6-8 weeks.

The software license is paid directly to the vendor at their public list price — we do not resell it or mark it up. Full breakdown on our pricing page.

FAQ

Frequently asked questions

Can we just extend our US ERP to Mexico?

Sometimes, through a third-party compliance add-on. It works, but you inherit a permanent dependency on that vendor and their release cycle. For a small Mexican entity, a local ERP that stamps natively is usually simpler and cheaper to own.

Is Odoo a serious option for a US company?

For a Mexican subsidiary, yes — it handles CFDI 4.0, the payment complement and electronic accounting natively in its licensed edition. We run our own company on it. For a large multinational already standardized on SAP, keeping SAP and adding the Mexican localization usually wins. We implement both.

How long before we can legally invoice?

Four to six weeks is realistic for a clean setup, and the constraint is usually your certificate and provider paperwork rather than the software.

Do you work in English and on US hours?

Yes. We are based in Monterrey with an entity in Texas, we work Central Time and our team is bilingual. That is the whole point of nearshore.

Who owns the configuration and any custom code?

You do, entirely, with the repository and documentation. No black boxes and no lock-in.
