Document checklist for successfully collecting a business debt

Debts are not lost due to lack of reason. They are lost due to lack of proof.

When it comes time to collect a business debt, the creditor company often discovers two realities at once: the debtor is already trained to delay, and the process only moves at the pace of the paperwork. That's why this article exists.

In this guide, you will find a practical checklist of documents for successfully recovering a business debt, from the amicable phase to injunction and, if necessary, enforcement. The aim is to reduce disputes, avoid objections and speed up the recovery of money.

Before we begin: what does it mean to have “sufficient documents”?”

To recover a business debt, it's not enough to have issued invoices. You need a coherent set of documents to prove three things:

• That a trade agreement existed.

• That your company delivered what it promised.

• Payment is overdue and has not been made.

In practical terms, to quickly collect a business debt, documents must tell the whole story without any gaps.

The bigger the hole, the greater the likelihood of the debtor contesting, delaying, and turning a simple process into a lengthy conflict.

“Source” documents: proving there was an agreement

When collecting a business debt, the first hurdle is straightforward: the debtor will try to claim they didn't contract, didn't agree, or that it was “just a quote”. This is where the originating documents make all the difference.

Contract, accepted offer or approved quote

If a contract exists, that's great. If not, an email acceptance, a purchase order, or an approved quote can be sufficient to safely collect a business debt.

What should I confirm in these documents:

• • Identification of parties and NIPC.

  • Subject of the supply or service.

  • Price and payment terms.

  • Delivery or execution deadlines.

  • Penalties, interest, termination clauses, if any.

General conditions and proof of acceptance

Many companies have general terms and conditions and assume that “they are on the website”. However, to collect a business debt, it is advisable to be able to prove that the client had access to them and accepted them.

Common forms of evidence:

• • Conditions attached to the proposal.

  • Link sent by email with express acceptance.

  • Signature on a document that refers to the general conditions.

“Execution” documents: prove you delivered what you invoiced

To recover a business debt, it's not enough to say “I did it”. You need to be able to show “I did it, on this date, for this client, under these conditions”.

Delivery of goods: guides, CMR and signed receipt

When supplying goods, the documents that are most helpful in chasing a business debt are those that close the discussion of “I didn't receive it”.

Include in the file:

• • Transport guide and delivery document.

  • CMR, when there is international transport.

  • Signed receipt document, where possible.

  • Carrier's proof of delivery, with date and location.

Provision of services: reports and acceptance

In services, the debtor tends to attack the quality or completeness. To collect a business debt, proof of service must be objective.

Useful examples:

• • Intervention reports or execution reports.

  • Technical support records and closed tickets.

  • Timesheets or horários.

  • Minutes of meeting with client validation.

  • Emails to confirm delivery and acceptance.

If your company works in phases, use clear language: phases, stages, checkpoints and interim deliverables. This helps to collect a business debt when a client tries to “block” payment with vague discussions.

Financial documents: proof of maturity, amount and balance

To collect a business debt, the money has to be clearly explained. The debtor loves confusion: outstanding invoices, credit notes, partial payments, balances that don't add up.

Invoices, debit notes, and credit notes

Ensure that, to collect a business debt, you have:

• • Invoices issued relating to the service or order.

  • Debit notes, where applicable.

  • Credit notes issued, if any, to avoid ordering more.

  • Current account statement with closing balance.

Proof of expiry and default

Include:

• • Agreed payment terms.

  • Clear due date on each invoice.

  • Proof that the deadline has passed without payment.

If the client requested an extension, keep proof. To collect a business debt, every email counts.

Late payment interest and collection costs

In many debts between companies, there are late payment interest charges and, in certain cases, indemnity Minimum cost for debt collection in commercial transactions. To effectively collect a business debt, present the interest rates accurately and without exaggeration. An opaque calculation is an invitation for opposition.

Communications documents: what the debtor said (or didn't say)

When collecting a business debt, correspondence is gold. Often, the best document isn't the contract. It's the email where the debtor admits they're behind.

Confirmation emails, orders and acknowledgement of debt

Seek and keep:

• • Order confirmation.

  • Request for invoice to be issued.

  • Messages asking for an extension.

  • Acknowledgement of debt, even if informal.

Formal request for payment

A well-drafted letter before action greatly improves the likelihood of recovering a business debt without going to court.

The ideal is that it includes:

• • Outstanding balance and invoice breakdown.

  • Short payment deadline.

  • Interest indication, if applicable.

  • Notice that we will proceed to injunction or action.

Injunction documents: the quickest route to an enforceable title

When the debtor ignores, the question changes: how to collect a business debt with a mechanism that forces a response.

The injunction procedure allows the creditor to obtain an enforcement order if the debtor does not object, and it is processed by the National Injunction Office.

What do I need to have ready for the injunction application?

To recover a business debt via injunction, organise:

• Full identification of the debtor and correct address.

• Simple presentation of facts, without excess text.

• List of invoices and amounts.

• Capital separate from interest and other amounts.

• Supporting documents, contract, order, proof of delivery.

The aim is to avoid opposition. When the debtor realises they are actually being pursued, they can pay or try to delay with an objection.

If you need to understand the link between injunction and execution, see Injunctions and Executive Actions.

Documents for execution: when is it necessary to go further?

Sometimes a company obtains a writ of execution but cannot recover the money. To practically collect a business debt, enforcement requires more information. A writ of execution is the process that allows for coercive collection through seizure, provided there is a writ of execution.

What must be attached for the enforcement?

To recover a debt in a business execution, you typically need:

• • Executive title, for example, injunction with an enforcement clause.

  • Well-completed execution request.

  • Proof of payment of the court fee, where applicable.

And, in practice, the more you know about assets, the more effective you can be at recovering a business debt.

• • Bank account indicators.

  • Debtors' book debts.

  • Vehicles, equipment, properties.

  • Signs of invoicing and activity.

Some practical guidance on forms and the framework of enforcement proceedings can be found on the courts' portal. 

Risk documents: when the debtor is failing

To successfully collect a business debt, you also need to identify risk signals early on.

If there are signs of insolvency, time can be your greatest enemy. In certain situations, preparing your defence for your credit in insolvency is more important than insisting.

Documentation errors that cause financial losses

Many creditors lose out because they haven't properly documented the relationship from day one. If you want to collect a business debt, these are the mistakes you should avoid.

• Do not keep proof of acceptance of the proposal.

• Failure to have proof of delivery or actual performance.

• Issue invoices without clear reference to the service or order.

• Mixing balances and not controlling the current account.

• Asking for interest or costs without transparent calculation.

• Using the wrong address and failing notifications.

• Only act when the debt is already old and the debtor no longer has assets.

How to put together a dossier in 30 minutes?

You don't need weeks. You need a method. If you want to quickly collect a business debt, follow this sequence.

• Create a folder per client and a subfolder per debt.

• Place the source documents, contract and proposal first.

• Then the execution documents, deliveries and reports.

• Then the financial documents, invoices, current account, payments.

When a file is like this, collecting a business debt becomes more predictable.
