The essentials
- Two documents depending on the customer: e-Factura between taxpayers, e-Ticket for end consumers.
- The CAE authorizes you for a numbering range with an expiration. It runs out, and when it does, you stop.
- The receipt is the XML; the printed sheet is its representation.
- Promec doesn't yet issue CFE in Uruguay.
Of all the countries in the region, Uruguay has the detail that turns into an operational problem fastest: your permission to issue receipts is finite. It's not a switch you flip once; it's a numbering range with a date. A shop that invoices a lot in a given month can run out of CAE without having done anything wrong.
What Promec does today in Uruguay. The system runs the whole shop — AI quotes, scheduling, the mechanic's app, inventory, the customer portal and accounting — and it invoices with your own series, your own taxes and your own currency. What it
doesn't do yet is issue electronic fiscal receipts (comprobantes fiscales electrónicos) with the DGI. That integration is in development and we don't have a date for it; until then, issuing stays with your current invoicing provider. We're telling you this before you sign up, not after:
here is where direct integration already exists.
Which document applies
As in the rest of the region, the decision isn't made at checkout: it's made when the vehicle comes in, because it determines what information you need to have asked for.
The CAE: the permit that expires
What to watch before it's urgent
How much numbering you have left per receipt type, and when the range expires. A system that doesn't warn you about that will leave you stranded on your busiest day. If your software doesn't show it, put it on your own calendar.
What a Uruguayan shop should have sorted out
- Company customer's RUT captured when opening the work order.
- Quote with labor and parts in separate line items.
- A warning when the CAE is running low, before it hits the limit.
- The XML files kept and downloadable, not just the PDF.
None of that gets solved by the invoicing tool: it gets solved by the program you run your shop with, which is where the information is born.

FAQ
e-Factura or e-Ticket?
It depends on who the customer is. The e-Factura is for transactions between taxpayers, with the recipient's RUT. The e-Ticket is for end consumers. A shop issues both: e-Factura for the fleet that brings in its vans, e-Ticket for the individual dropping by for a service.
What's the CAE, and why do I run out of it?
The CAE is the Constancia de Autorización de Emisión (Issuance Authorization Confirmation): the DGI authorizes you in advance for a numbering range for a given receipt type, with a validity period. It's not an indefinite permit. When you use up the range or the date arrives, you have to request a new one. It's the most common cause of 'the system won't let me invoice' on a Monday morning.
Do I have to send something to the DGI every day?
The Uruguayan model includes periodic reports in addition to sending the receipts themselves. The deadlines and details are set by the DGI, and it's worth confirming them with your accountant. What matters when choosing software is whether those submissions are automatic or whether someone has to remember to do them.
Is the PDF I give the customer the receipt?
No. The receipt is the authorized XML; the printout is its representation. Keep the XML files: they're what counts.
Does the DGI certify shop software?
No. It authorizes electronic issuers and authorizes numbering ranges. There's no seal for 'shop software approved by the DGI.'
