Electronic receipts for auto shops in Ecuador: SRI, access key and RIDE

The essentials

The receipt is a signed XML authorized by the SRI; the RIDE is only its printout.
You need an electronic signature from an accredited entity. It expires, and the day it does, you stop issuing receipts.
The access key identifies every receipt and is what the customer uses to look it up.
Promec doesn't yet issue electronic receipts in Ecuador.

The most common mix-up at an Ecuadorian shop isn't a tax issue, it's an archiving one: people believe the invoice is the printed sheet. It isn't. The sheet is the RIDE. The invoice is an XML that the SRI authorized, and that's the file you need to keep.

What Promec does today in Ecuador. 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 receipts (comprobantes electrónicos) with the SRI. 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.

The chain, step by step

Your system builds the receipt's XML with the transaction data.
It signs it with your electronic signature certificate.
It sends it to the SRI, which authorizes it or returns it with observations.
Once the receipt is authorized, the RIDE is generated for the customer.

Each step can fail for a different reason, and it's worth knowing which one failed. A poorly built XML gets rejected on structure; an expired certificate never even gets signed; a denied authorization usually comes with a message pointing to the specific field.

The access key, taken apart

Inside that numeric string are the issue date, the receipt type, your RUC, the environment, the series, the number, a numeric code, the issuance type and a check digit. It's not just any sequential number: it's the identifier the receipt exists under in the SRI's system.

Where it breaks down at a shop

The regulation is the same for a shop as for a store. The difference is in how the information arrives:

The customer isn't there at checkout. They drop the car off in the morning and someone else picks it up in the afternoon. If tax details weren't requested when the vehicle came in, the receipt gets issued with whatever's on hand.
The amount changes along the way. The order opens over a noise complaint and ends up covering a clutch and a bearing. If the quote isn't kept live in the system, the receipt gets pieced together by hand at the end.
Parts and labor get mixed together. It doesn't matter for the receipt, but it matters for your margin: if they're not separated into line items, you'll never know how much you make per hour.

What to ask of the software

Whether it issues receipts or not, the management program has to leave the transaction in a state where issuing is mechanical: complete customer tax details on file, a quote with separate line items, a closed order with the final amount, and a clean export to whoever issues the receipt or to your accountant.

When that's solved, switching providers is a formality. When it isn't, any invoicing tool turns into a second job.

FAQ

What exactly is the access key?

It's the receipt's unique identifier, a numeric string that encodes the issue date, the receipt type, the issuer's RUC, the environment, the series, the number, a numeric code, the issuance type and a check digit. It's what lets the receipt be located, and it's what appears on the RIDE so the customer can look it up.

Is the RIDE the invoice?

No. The RIDE is the Representación Impresa del Documento Electrónico (Printed Representation of the Electronic Document): the sheet or PDF you hand the customer. The receipt is the authorized XML. If your system doesn't keep the authorized XML files and only gives you the RIDE, your fiscal archive is incomplete.

I need an electronic signature. What kind?

An electronic signature certificate issued by an accredited certification authority in Ecuador. Without it the XML can't be signed, and without a signature there's no authorization. Like any certificate, it expires: the expiration date deserves to be somewhere you'll see it, because the day it expires, the shop stops issuing receipts.

Can I issue receipts if the connection goes down?

The regulations provide for issuance modes that let you continue and regularize things afterward. The details and deadlines are set by the SRI and change, so confirm the current procedure. What is worth checking before contracting a system is whether it plans for that scenario or simply stops working.

Does the SRI certify shop management software?

No. The SRI authorizes receipts and accredits signature certification authorities. There's no seal for 'shop software approved by the SRI.' If someone sells it to you that way, they're describing something that doesn't exist.
