Anyone looking for a business management system in Portugal ends up at the same names: Primavera, PHC, Sage, and for larger companies SAP. They are mature products and, in most cases, the right choice. It is worth understanding when they are not.
What a market product does better
An off-the-shelf ERP brings decades of finished work: accounting compliant with Portuguese law, communication with the tax authority, automatic legal updates, a partner network that knows how to implement it. Building that from scratch would be absurd and we recommend it to nobody.
If your operation fits the product model, buying is cheaper, faster and less risky. Full stop.
The sign the product stopped fitting
The symptom is always the same and easy to recognise: there are parallel spreadsheets nobody can eliminate.
The ERP handles invoicing and accounting, but site cost control lives in a sheet. Or production planning. Or commission calculation. Someone maintains that sheet, everyone depends on it, and it never enters the system because the system has nowhere to put it.
When that happens, the company is paying twice: the product licence and the time of whoever maintains what the product does not do.
The three situations where building pays off
Customisation costs more than the product. When the customisation budget for an ERP exceeds the cost of building the specific module from scratch, the maths has flipped.
Per-user licensing becomes heavy. Products charge per user. If you want to give access to fifty people on the shop floor or on site, the recurring cost can quickly exceed the one-off investment in your own system.
The integrations you need do not exist. If you are going to have to commission custom integrations anyway, part of the product advantage has gone.
What is usually the right decision
In most cases it is not replacement. It is keeping accounting and invoicing in the product you already use, and building custom only the layer where the pain is: site control, production planning, CRM, client portal. That layer connects to the existing product and eliminates the parallel spreadsheets.
It is cheaper than a full migration, carries far less risk and solves the real problem.
How to know which side you are on
Add up what you spend today on licences, on customisations and on the time of whoever maintains the parallel spreadsheets. If that total exceeds the cost of building the missing layer, the decision is clear without further analysis.
In the diagnosis we run that calculation with you, and we say when the answer is to stay with the product you already have.
