Cancelling SRI Invoices: Your Deadline Is October 7

It is Wednesday afternoon and Rosa, owner of a stationery store in Loja, receives a message from a customer: "Hey, last month's invoice came out with the wrong RUC, can you correct it for me?". Rosa opens the SRI portal, looks for the cancellation option and discovers she can no longer do it. She missed the deadline by three days.

Rosa is an illustrative character, but her situation is real for many businesses. Since the SRI adjusted the rules for cancelling electronic receipts, the window for correcting errors is shorter, and many people are still not aware of it.

If you issued invoices in September 2026, this reminder is for you: the deadline to request their cancellation is Wednesday, October 7.

What the rule says

Resolution NAC-DGERCGC25-00000017 of the Internal Revenue Service (SRI) updated the guidelines for cancelling sales receipts, withholding receipts and supplementary documents issued electronically. According to the resolution and analyses published by specialized firms, the most important points are:

• Cancellation deadline: up to the 7th day of the month following the issuance of the receipt. Calendar days are counted, including weekends and holidays.
• Recipient acceptance: the cancellation request must be accepted by whoever received the receipt within five business days. If they reject it or do not respond, the cancellation does not proceed and the receipt remains valid.
• Final consumer: since January 1, 2026, invoices issued to a final consumer cannot be cancelled.
• Immediate issuance: since 2026, electronic receipts must be transmitted to the SRI immediately, on the same date as the transaction.

A practical example: an invoice issued on September 15 can only be cancelled until October 7. After that date, a different route will apply, such as a credit note, depending on the case.

Why so many businesses miss it

The problem is usually not bad intent, but habit. For years the deadline was longer and many businesses reviewed their errors "when there was time". Now, with only seven days of the following month, an error detected mid-month can be left with no option for cancellation if nobody reviews it in time.

On top of that, cancellation no longer depends only on you: if your customer does not accept the request in the SRI system, it does not proceed. If you leave it until the last day, you may not manage to reach them.

Volume also plays a role. A business that issues few invoices a month can review them from memory, but when there are dozens or hundreds, an error easily hides among the rest. That is why the solution is not to "be more careful", but to have a fixed review time and a tool where you can find each receipt in seconds, with its details in plain view.

5 habits so you don't run out of time

1. Review your receipts every week. Spend 15 minutes every Friday reviewing the invoices issued: RUC or national ID (cédula), amounts, payment method and customer details.
2. Mark the 3rd of each month on your calendar. That way you have time to request the cancellation and for your customer to accept it before the 7th.
3. Let your customer know before requesting the cancellation. A call or a message prevents the request from going unanswered.
4. Check the details before issuing. With immediate issuance, the best time to avoid errors is before invoicing. Ask for the RUC or cédula in writing whenever possible.
5. Talk to your accountant. Every case has nuances: what should be cancelled, when to issue a credit note and how it affects your tax returns. Do not stay in doubt.

Other useful reminders this week

• Backups: if your invoices or your accounting live on a single computer, make a copy somewhere else today.
• Electronic signature: check the expiration date of your signature. If it expires, you will not be able to issue electronic receipts.
• Passwords: change your SRI portal password if more people than necessary know it.

The outcome and the lesson

After that scare, Rosa changed her routine. Every Friday she reviews the week's invoices and on the 3rd of each month she does one last check. Since then, any error is corrected on time and without stress.

The lesson: tax rules change, and what used to be a small oversight can now be costly. A simple review habit saves you problems and awkward conversations with your customers.
