What the Lamosa addenda is

It is a block of commercial data that Lamosa asks for inside your invoice XML to find their order and pay you. It goes after the stamp, so it doesn't change the CFDI's validity with the SAT.

Manufacturing and consumer goods companies check your invoices against their purchasing system, which is almost always SAP or Oracle. The addenda carries the data their ERP needs to find the order and the receipt.

Data it usually asks for

Supplier or vendor number
Purchase order and line item
Goods receipt or warehouse entry number
Cost center or plant
Buyer's email or code

Each company defines its own addenda. The exact fields are in the manual your buyer or the Lamosa accounts payable team gives you.

Questions about the Lamosa addenda

What people ask us most before invoicing with an addenda.

Ask an advisor

How much does the Lamosa addenda cost?

$555 per year, VAT included, and you don't need Premium. If you invoice several companies with addendas, Premium includes all of them for $450 per month or $4,500 per year. Either way, each CFDI uses one stamp from your package.

Does the Lamosa addenda affect the stamp?

No. The addenda goes in the cfdi:Addenda node, outside the original string, so the SAT doesn't check it and it doesn't change the seal or the Timbre Fiscal Digital. Lamosa checks it.

What data do I need to invoice Lamosa?

Whatever its addenda manual asks for. In manufacturing and consumer goods it is usually: supplier or vendor number; purchase order and line item; goods receipt or warehouse entry number; cost center or plant; buyer's email or code.

How do I turn on the Lamosa addenda?

Get a quote from an advisor. They go over the Lamosa manual or XSD with you, we set it up in your account and let you know when it is ready to invoice.

Can I invoice Lamosa from my ERP?

Yes. With API v5, included in the service, your system sends the CFDI data and the addenda data in the same request and gets back the stamped XML with the addenda. You can also invoice from the web portal without integrating anything.
