How does a debt collection agency work? The step-by-step plan explained

A debt collection agency works in four phases: file building, written demand, telephone contact, and — as a means of pressure — the announcement of legal proceedings. What happens in between (emails, payment arrangements, reminders) varies by agency, but the structure is the same everywhere. Below, we explain the step-by-step plan, including the timeframes and the underlying logic.

Piet the plasterer once thought that a collection agency was “a sort of street gang with better letters.” Not quite. It is a structured process involving legal pressure, not a physical approach. Below is how it really works.

The short answer: how does a debt collection agency work?

1. Phase 1 — File building. You provide the invoice, general terms and conditions, correspondence, and debtor details. The agency verifies whether the claim is legally sound.
2. Phase 2 — Written demand. A formal demand with a deadline (often 5 to 10 working days), mentioning statutory collection costs and interest.
3. Phase 3 — Telephone contact and reminders. Calling rounds and, if necessary, a payment arrangement. Most debts are resolved here.
4. Phase 4 — Referral to the court. If the out-of-court process fails, a summons will be issued — via a lawyer.

Phase 1: file building and assessment

The first day or two revolves around paperwork. The agency receives your file and checks:

• Is the invoice drawn up correctly (date, amount, VAT, due date)?
• Are the general terms and conditions applicable and have they been properly provided?
• Has a previous reminder been sent and — for consumers — a correct 14-day letter?
• Is the debtor identifiable and reachable?
• Is the claim due and payable (due date passed, no undisputed grounds for suspension)?

Is something incorrect? You will be informed before the agency goes out to collect. A shaky claim ends in an expensive procedure that you lose — a waste of everyone's time. For the rules regarding the 14-day notice: the Debt Collection Costs Act (Wet Incassokosten) and the official BIK Decree (Besluit BIK) on wetten.overheid.nl.

Phase 2: the written demand

The summons is the official opening of the process. What it contains:

• The claim: invoice number, amount, due date.
• The statutory (commercial) interest accruing from the due date.
• The extrajudicial collection costs in accordance with the WIK.
• A payment term, often 5 to 10 working days.
• The announcement that legal action will follow in the event of non-payment.

Many debtors pay after just this letter — the combination of professional letterhead, escalating costs, and the legal threat works. More about the content in the demand letter.

Phase 3: telephone contact and possible payment arrangement

Is your debtor not responding? Then comes phase 3: calling. Good collection agencies follow through here in a dignified manner. No shouting matches; just clarity. Three typical outcomes:

• The debtor pays immediately. Done.
• Payment arrangement. For example, in monthly installments. Wise to agree to if the debtor really cannot or will not pay. More relevant to payment arrangements that do not go according to plan.
• The debtor remains silent or refuses. Then you are approaching phase 4.

In the event of disputes — “I do not believe I owe anything” — things become more complicated. Out-of-court collection only works for undisputed claims. If there is a dispute regarding the amount or existence, proceeding to legal proceedings (or consultation through a lawyer) is generally more logical. See also disputed invoice collection.

Phase 4: referral to the judge

If the out-of-court process fails, the case can go to court — through a lawyer. Three caveats:

• You pay court fees and, above €25,000, attorney fees. Before you begin, calculate whether the claim justifies those costs.
• A judgment in itself does not fill your bank account. After that, the bailiff comes for the execution (seizure, possibly sale).
• In an urgent case, summary proceedings can yield results faster. See debt collection summary proceedings.

The complete walkthrough with all legal instruments is included in the debt collection procedure.

Lead time: how long does it take?

An average out-of-court collection process takes two to six weeks. In simple cases — small amounts, clear claim, accessible debtor — often shorter. In complex situations (debtor in financial difficulties, disputed claim, unreachable party), longer.

The judicial phase adds three months to a year to that—depending on the workload at the court and the complexity. Execution can then take another few weeks. Paying quickly is always to both your advantage.

What are you doing yourself in the meantime?

Three things that help, even after you have handed it over:

• Do not immediately stop supplying or cancel. Do so thoughtfully. Statutory rights such as suspension or termination are often permitted, but only with the proper legal basis. Seek advice first.
• Gather supporting documents. Should it come to legal proceedings, your lawyer will have everything ready: confirmation of engagement, communications, and proof of completion.
• Limit the damage. A payment arrangement with a paying customer is worth more than a judgment on an empty scale. Be pragmatic.

Honest recommendation

How a debt collection agency works is no secret — what works is the combination of professionalism, legal pressure, and finally taking decisive action. Ensure your own preliminary work (invoice, reminder, demand letter) is in order before handing it over; then the process moves four times faster.
