Compliance
The complaints book: what binds anyone serving consumers in Portugal
The electronic format is compulsory for virtually every supplier of goods and services, and a complaint goes straight to the sector regulator.

Who is bound, and to what?
Virtually every supplier of goods and provider of services dealing with consumers in Portugal, including online-only sellers. The obligation is twofold: make the electronic format available and display visibly both the access route and the competent regulator.
A complaint submitted in the electronic format reaches the company and the sector regulator at the same time. There is no intermediate filter, which changes the calculation for anyone thinking of leaving complaints unanswered.
What does this force in the operation?
Having someone responsible for monitoring the channel every working day, replying within the legal deadline and keeping the history. In outsourced operations, that work has to be explicit in the contract: who monitors, who drafts, who approves and who answers to the regulator.
It is worth treating complaints as process signal rather than isolated incidents. Three complaints about the same step of the customer journey are worth more than a satisfaction survey.
How does the electronic format work?
The consumer accesses a national platform, identifies the supplier and submits the complaint. From there the complaint goes simultaneously to the company and to the sector regulator, without passing through any company filter. The company is notified and has a legal deadline to reply.
The company has to make access to the electronic format visibly available, including on its websites, and state which regulator is competent. For anyone selling across several sectors there may be more than one, and naming the wrong one is itself a breach.
The physical format still exists for premises with face-to-face service, and the two obligations coexist. A shop with a counter and online sales has to meet both, which in practice means two channels to monitor and one record to keep.
Who enforces it and what can happen?
Enforcement falls to the sector regulator and, across sectors, to the economic enforcement authority. Consequences range from a fine to publication of the decision, and the most penalised breach is not having complaints but failing to provide the book or failing to reply within the deadline.
It is worth distinguishing this clearly in an operation: a complaint well answered within the deadline is a process working. An unanswered complaint is a separate infringement, regardless of who was right about the underlying problem.
There is also the aggregate reputational effect. Regulators publish sector data and complaint patterns, and abnormal volume against a specific operator attracts enforcement attention that would not otherwise have existed. Complaints are a signal before they are a problem.
How do you answer a complaint well?
Within the deadline, in writing, answering what was complained about rather than what it would be convenient to have been complained about. A reply that reframes the grievance into a version easier to refute is read as exactly that by the consumer and by the regulator, and usually produces a second complaint about the reply.
The structure that works is short: acknowledge what happened with facts and dates, say what was established, say what will be done and when, and give a direct contact. Avoid defensive language and avoid citing contract clauses as the main argument, which is technically correct and persuades nobody.
In European Portuguese, register matters particularly here. An angry consumer addressed with excessive familiarity reads that as not being taken seriously; addressed with legal formalism reads it as being pushed away. The right point is formal courtesy in plain language, which is exactly the register hardest to produce from a script converted from another variant.
How is this set up in an outsourced operation?
With four roles written into the contract: who monitors the channel every working day, who drafts the reply, who approves it before it goes out, and who answers to the regulator if there is a proceeding. The four can be different people; none can be undefined, and the last is always the company's.
Daily monitoring is what fails first, usually because it looks trivial. A channel checked on Mondays loses half the legal deadline in half the cases, and the problem only surfaces when the first deadline is missed, which is too late to be a warning.
It is worth instrumenting this like any other queue: time to first reply, percentage answered within the deadline, and recurrence by root cause. Three complaints about the same step in the customer journey are worth more than any satisfaction survey and cost less to obtain.
And alternative dispute resolution?
It exists in parallel and is frequently confused with the complaints book. Consumer dispute arbitration centres resolve disputes bindingly or through mediation, and companies have to inform the consumer which body is competent for their sector.
Some sectors have mandatory adherence and, for low-value disputes, the arbitral decision can bind the company regardless of its wishes. This changes the calculation: a small-value dispute can be decided against the company without any ordinary court being involved.
For a customer support operation, the practical implication is that record quality matters. When a dispute reaches arbitration, what exists in writing about the case is the available evidence, and an operation that resolved everything by telephone without recording arrives at that stage with nothing to show.
What should the internal record contain?
Date received, channel, consumer identification, a description of what was complained about in their own words, and the internally assigned root cause classification. The consumer's own words matter: rephrasing at intake already biases all the analysis that follows.
Then, what was established, by whom and when, the reply sent, and the send date against the statutory deadline. That last one is the proof of compliance, and it is frequently the one missing because nobody recorded it explicitly.
And the follow-up: whether there was a second complaint on the same matter, whether the case went to arbitration, and what the outcome was. Without this it is impossible to distinguish a resolved problem from one that merely stopped being reported on that channel.
Root cause classification is what turns the record into a management instrument. If the categories are too broad, every complaint lands under service and nothing is learned; if too fine, nobody applies them consistently. Between eight and fifteen categories is usually the useful point.
Which reply mistakes generate a second complaint?
Replying after the deadline, which generates a separate complaint about the lack of reply and is the worst of both worlds: the original problem remains and a formal, easily demonstrable breach is added.
Replying to a different version of what was complained about. The consumer immediately reads that they were not read, and the second complaint becomes about how they were treated rather than about the product, which is substantially harder to resolve.
Citing contract clauses as the main argument. It is technically correct and communicates that the company is defending itself rather than resolving, and in a consumer context there are mandatory rules a clause does not displace, so the argument is frequently weak as well.
And promising an action without a date. We will look into it reads as we will do nothing. A concrete date, even three weeks out, closes more cases than a vague promise of immediate resolution, because it is verifiable and because it respects the complainant's time.
