How much does it cost to build an electronic invoicing system in Ecuador?
At RoxiumLabs, a basic ERP structure with electronic invoicing for Ecuador starts between USD 750 and USD 1,500, built on components we already have in place. The price rises with two factors: how many of the company's processes have to be modelled, and how many distinct roles the system must support.
This is the question hardest to find answered with concrete numbers, because almost nobody publishes prices. We prefer to: it lets anyone enquiring know whether they are in range before investing time in meetings.
The range for a basic structure
A basic ERP structure with electronic invoicing for Ecuador starts between USD 750 and USD 1,500. That range is possible because we do not start from zero: the components covering the regulated part, which is the most delicate and time-consuming to build from scratch, are already built and tested.
- Electronic signing of the receipt in XML with the taxpayer's certificate.
- Transmission to the SRI service and handling of authorisation responses.
- Multi-client structure with separate data, team and permissions.
- Receipt loading, including bulk import.
- Management dashboard with the status of every document.
The two factors that drive the budget
Beyond the base, price depends almost entirely on two variables. It is worth measuring them before requesting a quote, because any serious provider will ask.
1. Number of processes to model
Every in-house process the system has to reproduce is analysis, development and testing work. Issuing invoices is not the same as issuing invoices that also need two levels of approval, assignment to a cost centre, a task raised for the team and a notification to the client. Each of those steps is a rule to understand, build and validate with the client.
2. Number of distinct roles
Roles multiply the work more than expected, because each one adds permissions, views and test cases. A system with two roles is built quickly. One where the owner, the accountant, the assistant, the external auditor and the end client each see and do different things has considerably more surface, especially when permissions are resource-level rather than generic roles.
What is quoted separately
| Item | What it depends on |
|---|---|
| Third-party integrations | Number of systems, quality of their API, whether they are documented |
| Data migration | Volume and condition of the previous system |
| Custom automation | How many manual steps are removed and how complex they are |
| Specific reporting | Number of reports and level of detail |
| Mobile application | Whether access is needed away from the desktop |
| Maintenance and regulatory changes | Quoted monthly, separate from development |
The cost that is not in the budget
An electronic invoicing system is not finished the day it is delivered. SRI regulations change, and when they do the system has to be adapted. In January 2026, for example, receipt transmission became immediate and removed the previous four-business-day window, forcing changes to systems that had been working fine. It is worth agreeing who absorbs that work, and under what arrangement, before signing.
How to request a useful quote
To compare budgets across providers on equal terms, bring these five facts to every meeting:
- How many receipts the company issues per month.
- How many distinct roles will use the system and what each one can do.
- Which current systems have to keep working and whether they have an API.
- Which internal processes are non-negotiable and which can be adapted.
- Whether there is historical data to migrate and in what format.
With that, any serious provider can give you a real range instead of an invented number. And if someone quotes without asking any of this, the number will change later.

Go to sri.gob.ecFrequently asked questions
- Does the USD 750 to 1,500 range include the electronic signature certificate?
- No. The electronic signature certificate is issued by an accredited certification authority and is contracted separately, in the taxpayer's name. The development integrates that certificate but does not provide it.
- Why is that range lower than a traditional ERP?
- Because it is not built from scratch. The components handling XML signing, transmission to the SRI and the multi-client structure are already built and tested in previous projects, so the project starts from a working base.
- How much does maintenance cost afterwards?
- It is quoted separately on a monthly basis, because it depends on the size of the system and how many regulatory changes have to be absorbed. It is worth defining it in the initial contract rather than after delivery.
- Is it better to build or buy an existing product?
- For most companies, buying is the right call. Building makes sense when there are in-house processes no product covers, or when per-user licence costs are already comparable to building. We cover this in detail in our guide on custom versus off-the-shelf software.
