What happens with two systems
The same sale, entered twice
QuickBooks for the US side and CONTPAQi or Aspel for the SAT. Every re-entry is another chance for an error.
Inventory that changes owner when it crosses
Goods move from the Mexican company to the US one and the system doesn’t reflect it. That’s where units and margin go missing.
Consolidating is a monthly spreadsheet
Each company closes in its own system and someone pulls it together by hand to see how the whole business is doing.
What it looks like in one Odoo
License directly to Odoo
You pay the license directly to Odoo; we charge for the implementation. We don’t resell licenses.
Migration without stopping operations
Catalogs, balances and history from QuickBooks, CONTPAQi or Aspel, verified against the originals.
Two companies, one instance
The Mexican and the Texas company in the same system, with automatic inter-company transactions.
CFDI and US invoice from the same sale
The export CFDI with the foreign trade complement, and the invoice with sales tax on the other side.
Two currencies
Pesos and dollars with an exchange rate per transaction and bank reconciliation in each country.
Inventory in transit
What’s crossing shows up as such, with its cost and its legal owner.
What we don’t doWe explain what the system has to handle; the tax side (registration, nexus, deductions) you decide with your CPA in the US and your accountant in Mexico.

- Step 01 · The sale
Two documents, one entry

- Step 02 · Mexican side
CFDI with the foreign trade complement and Carta Porte
The export CFDI with the foreign trade complement comes from the same sale. On the Mexican side, the Carta Porte is generated from the same trip data.
- Step 03 · US side
US invoice with sales tax
In Texas, the state sales tax rate is 6.25% and cities and counties can add up to 2%, for a combined maximum of 8.25%.

Is Odoo an alternative to QuickBooks?
For a company operating in both countries, often yes, because it keeps both sets of books in one system. If you only operate in the US and QuickBooks is enough, we’ll tell you.
How much does it cost?
It depends on how many companies, users and processes are involved. That’s why we give you scope, date and price in writing before you sign, after seeing your operation.
