A customer disputes an invoice. Sales operations knows the delivery, the account manager knows the negotiation and finance knows the balance. Each team holds part of the answer, but nobody knows who can decide what happens next. The case circulates through three inboxes while automated reminders either continue or remain paused without a review date. The starting point is to distinguish the decisions. Confirming that work was performed, correcting an accounting amount and granting a commercial concession require different assessments. A useful organisation assigns each decision and gives one person responsibility for assembling the conclusions and replying to the customer. Coordinating the case does not mean having authority to make every decision within it. ## Define the dispute before assigning it “Unhappy customer” is not a sufficient case description. Identify the invoice, the amount challenged, the reason and the evidence behind the customer's request. Preserve the original wording before summarising it. A complaint about delivered quantities calls for different evidence from an orally negotiated discount or a price that differs from the accepted quotation. The initial record can be short: reference, amount, reason, missing evidence, owner and next review date. It should separate established facts from questions still being investigated. If the customer has not explained the objection, the next task is to clarify it, rather than send an undefined request through three successive internal approvals. France's Observatory of Payment Terms recommends identifying the people responsible for monitoring service or delivery acceptance on both the supplier and customer sides. That provides a practical foundation: the dispute process needs access to someone who understands what was actually performed.

It does not describe legal powers automatically attached to a job title. In a small business, one person may perform several roles, but they should still distinguish the checks they are making. | Question requiring a decision | Suggested owner | Expected output | | -------------------------------------------- | --------------------------------------- | -------------------------------------------- | | What was actually delivered or performed? | Sales operations or operational manager | Dated facts, reservations and evidence | | What remains after corrections and payments? | Finance | Supported balance and document treatment | | Will an additional concession be granted? | Authorised sales manager or management | Reasoned decision within delegated authority | | What will the customer be told, and when? | Case coordinator | Consistent response and next action | This distinction also helps the account manager. Finding an email that mentioned a discount does not require them to determine its accounting treatment alone. Equally, a correct accounting entry does not establish that the delivered service met the contract. Each contribution answers a bounded question and then becomes available to the coordinator. ## Investigate independent questions in parallel A sequential approval chain can create unnecessary waiting. Finance can reconstruct payments while sales operations finds delivery evidence. The account manager can check previous correspondence without waiting for both investigations to finish. However, a correction decision may depend on those findings and should follow the evidence required to support it. Set a realistic next step and identify cover for absence. “Sent to sales” says nothing about when the case will return. The coordinator needs a way to identify missing responses and request the agreed escalation. A meeting involving everyone is useful only when a joint decision actually remains to be made. Repeated handovers have a measurable cost. Assessing the [cost of a reminder across three teams](https://www.billabex.com/en/blog/payment-reminder-cost-three-teams/) helps reveal repeat investigations. The objective is to avoid someone searching again for information already checked because they cannot access the previous conclusion. It is not a reason to remove a justified control without assessing its purpose. ## A numerical example: correction versus concession Consider a hypothetical invoice for €10,000 excluding VAT, covering one hundred units at €100 each. The customer says ten units were not delivered and also requests a €500 discount for the inconvenience. Operational evidence confirms that four units were cancelled and the other ninety-six were received. The correction for cancelled units is therefore 4 × €100 = €400 excluding VAT. That finding does not automatically approve the additional €500 request. Sales management should consider that request separately, using the agreement, the facts and its delegated authority. If the full concession is accepted, the proposed total reduction is €900 excluding VAT, leaving €9,100 excluding VAT before tax treatment and any other account movements. If management declines the concession, the balance after the quantity correction alone is €9,600 excluding VAT. These alternatives explain why every adjustment should not be recorded as an “invoice error”. Here, the correction aligns the invoice with the confirmed quantity; the concession follows a separate commercial decision. The figures illustrate responsibility, not a VAT treatment for a real transaction. ## Approve the decision that actually commits the company Colleagues need to know the limits of their authority: amount, concession type, customer scope and conditions. Provide an escalation route for cases outside that authority or those creating a material contractual precedent. An internal approval threshold is an organisational choice and should not be described as a statutory debt collection threshold. For French contracts, Civil Code article 1193 establishes the principle of amendment by mutual consent, subject to legally authorised exceptions. An internal decision to offer a concession therefore does not itself settle what has been agreed with the customer. Obtain an appropriate contractual assessment when the consequences extend beyond a straightforward administrative correction.

The coordinator then checks that the [credit note has been allocated correctly](https://www.billabex.com/en/blog/unallocated-credit-note-balance-check/) and that collections tools use the updated balance. A commercial agreement missing from the accounting records is not enough to close the case cleanly. For a group operating in several European countries, record the entity and contractual framework concerned. A French source is relevant to French obligations; it should not silently become a legal rule applied to every foreign customer contract. ## Reply consistently and define what resolution means The customer response should connect the finding, the decision and the next step. Explain what was checked, what is being corrected and what remains under discussion. Avoid three departments sending different versions of the same answer. If the customer announces a payment date, record a [trackable payment promise](https://www.billabex.com/en/blog/verifiable-payment-promises/) with a clear amount and scope. A resolved dispute does not necessarily mean a paid invoice. Keep a resolution date, evidence of the agreement and a separate payment status. Follow-up can then resume on a verified basis while the original reason remains available for analysis. Over time, the team can identify whether particular references, products or commercial terms repeatedly generate disagreements. Where negotiation remains blocked, France's Business Mediator is an amicable route to assess according to the case's eligibility. Its FAQ describes an average duration of one to three months depending on complexity, with some longer cases. That indication should not become a target for fixing a routine internal invoice discrepancy.

Evaluate [debt collection software](https://www.billabex.com/en/debt-collection-software/) against this sequence: who can see the obstacle, who decides, which evidence supports the amount and how follow-up resumes. Your organisation retains control of its commitments while giving the customer an answer they can understand and verify. ## Sources - [Observatory of Payment Terms: good practice guide, November 2024, page 8](https://www.banque-france.fr/system/files/2024-11/Guide_Bonnes_pratiques_ODP_V6.pdf). - [Légifrance: Civil Code article 1193](https://www.legifrance.gouv.fr/codes/article_lc/LEGIARTI000032041314). - [Médiateur des entreprises: FAQ, particularly question 18](https://www.economie.gouv.fr/mediateur-des-entreprises/faq-le-mediateur-des-entreprises-votre-service).
