Electronic invoicing is no longer optional in Ecuador; it is the mandatory standard. In 2026, with real-time transmission already in force, understanding the process well is key to keeping sales flowing and avoiding fines. This guide covers the essentials for companies and RIMPE taxpayers.
Who is required to invoice electronically?
As a general rule, taxpayers must issue electronic receipts. For the RIMPE regime, it helps to distinguish two groups:
| Taxpayer type | Annual income | Electronic invoice? |
|---|---|---|
| RIMPE Entrepreneur | USD 20,001 to 300,000 | Yes, mandatory |
| RIMPE Popular Business | Up to USD 20,000 | Not mandatory (may use sales note) |
| General regime | No RIMPE cap | Yes, mandatory |
The 3 steps to start invoicing
- Verify your RUC on the SRI portal: it must be active with the correct economic activities.
- Get your electronic signature: the certificate that validates your receipts. It is processed in person or virtually with an authorized entity.
- Choose your invoicing software: the SRI offers a free basic tool, and there are commercial or custom solutions for higher volumes.
Free SRI tool or custom software?
The free SRI invoicer is a good entry point for small or new taxpayers. However, it has limits as your operation grows: little integration with your accounting or inventory, manual entry of each receipt, and limited control over transmission status.
- Free SRI software: ideal for low volume and simple operations.
- Commercial software: covers standard needs with monthly plans.
- Custom software: integrates invoicing, accounting, inventory, and the SRI into a single flow, with automation and your own reports.
When a company or accounting firm handles dozens or hundreds of receipts per day, automating invoicing stops being a luxury: it reduces errors, avoids late-transmission fines, and frees up team hours. At RoxiumLabs we build exactly that kind of platform.

- Does the electronic invoice replace the paper invoice?
- Yes. For obligated taxpayers, the electronic receipt is the valid document. Only some cases, such as RIMPE Popular Businesses, may use physical sales notes.
- Do I need internet to invoice?
- Yes, especially with immediate transmission in force since 2026. Offline contingency schemes exist, but the general rule requires a connection to authorize the receipt.
- Can I integrate invoicing with my current system?
- Yes. With custom development or connectors, electronic invoicing can integrate with your accounting, inventory, or ERP so the whole flow is automatic.
