What the IMSS-Bienestar addenda is

It is a block of commercial data that IMSS-Bienestar 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.

Government agencies and state-owned companies receive the invoice together with contract and delivery data. The addenda puts that data inside the XML so the payments team can check it without separate documents.

Data it usually asks for

Contract or order number
Supplier code or number
Receiving area, unit or warehouse
Delivery note or receipt number
In healthcare, sometimes the supply code

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

Questions about the IMSS-Bienestar addenda

What people ask us most before invoicing with an addenda.

Ask an advisor

How much does the IMSS-Bienestar 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 IMSS-Bienestar 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. IMSS-Bienestar checks it.

What data do I need to invoice IMSS-Bienestar?

Whatever its addenda manual asks for. In government and state-owned companies it is usually: contract or order number; supplier code or number; receiving area, unit or warehouse; delivery note or receipt number; in healthcare, sometimes the supply code.

Can I use the IMSS-Bienestar addenda today?

Yes. It is already in the app: get it for $555 per year or turn it on with Premium, choose it when you invoice and enter its data.

Can I invoice IMSS-Bienestar 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.
