How to choose software for an accounting firm in Ecuador: 9 criteria that matter

The question always arrives the same way: which accounting software is best. The honest answer is that the question is badly framed, because two firms of the same size can need opposite systems. One that lives off preparing tax filings needs a calculation engine and fiscal rules; one that administers its clients' operations needs tasks, deadlines and traceability. Almost no product does both well.

At RoxiumLabs we built two different accounting platforms for clients in Ecuador, with opposite approaches. The criteria below come from that experience: they are the things that in practice decided whether the system got used or whether the team ended up surrounding it with spreadsheets.

The 9 criteria

The three that weigh most

If we had to keep three, these would be them. The others can be worked around; these cannot.

1. Real per-client isolation

An accounting firm is not one company: it is several companies at once. The difference between a system that models that from the start and one that adds a client column to its tables shows up the day you need to give access to someone on the client's team without exposing the rest of the portfolio. In both platforms we built, the client is a first-class entity with its own tax ID, members and access grants, not a column.

2. Effective SRI integration, not export

Many systems claim to work with the SRI and what they do is generate a file someone uploads by hand. Since January 2026, with immediate transmission mandatory, that difference stopped being cosmetic. Real integration means signing the receipt with the electronic certificate and transmitting it through the SRI service at the moment of issue, handling responses and the contingency path when the service does not answer.

3. Being able to correct what the system calculates

This is the most underestimated criterion. No calculation engine covers every case, and the accountant will always need to overwrite a specific value. The problem is not allowing it: it is allowing it without leaving a trace. A serious system stores the original value, the corrected value, who changed it and when, so the filing remains defensible. We implemented it as a manual override layer on top of the automatic calculation, and it is one of the most used features.

Two approaches, two different systems

The two platforms we built solve different problems and illustrate the opening point:

• The first is filing-oriented: classification by economic activity, configurable tax brackets, withholdings with deduplication and direction control, Excel import and consolidated annual reports.
• The second is operations-oriented: invoices with lines and cost centres, automatic reading of the invoice PDF, tasks with a full history of status, assignment and field changes, deadline reminders and team notifications.

No off-the-shelf product we know covers both columns well. That is why the first step when evaluating is not to look at products, but to decide which of the two problems is the firm's bottleneck.

Where this is heading: automatic extraction from the SRI

A large share of an accounting firm's work is still downloading receipts from the SRI portal and loading them again into its own system. That is purely mechanical work and it is where we see the largest short-term automation margin. We are building a browser extension that takes receipts directly from the SRI portal and inserts them into the ERP with no manual step, removing that bridge entirely.

When assessing a system today, it is worth asking what the vendor's plan is for that bridge. It is where most hours are lost and what fewest products solve.

How to use these criteria in a demo

1. Bring two real clients with different structures and ask them to be loaded in front of you.
2. Ask to see a document's history after modifying it twice.
3. Ask them to simulate an SRI service outage.
4. Load the same withholding twice on purpose and watch what the system does.
5. Ask to grant access to a user who can see only one client and nothing else.

If the system passes those five, it is a serious candidate. If it fails the third or the fifth, the firm will end up covering the gap with manual work.
