The renovation team has left the site, the customer has moved into the premises, and the project manager is already coordinating the next job. From an operational perspective, the project looks finished. Then the customer replies to the final invoice with a different view of what should be paid.
Additional electrical points were apparently included in the original quotation. An upgraded countertop was discussed, but the customer says the price was never approved. There are also complaints about cabinet finishes, and the customer wants part of the balance withheld until the defects are resolved.
For a renovation contractor, this situation creates more than a collection problem. Suppliers and subcontractors may already have been paid, while the amount expected from the customer remains uncertain. The project’s reported margin may also depend on charges that are still being challenged.
Resolving the issue starts with understanding exactly what is disputed, what the records support, and how the uncertainty affects the business’s financial position.
Break Down the Balance Before Chasing Payment
A final invoice often combines several different items: the unpaid portion of the original contract, approved additional work, disputed variations, and amounts subject to contractual retention. Treating everything as one overdue balance can make a disagreement harder to resolve.
Consider a hypothetical renovation project with an original contract price of S$120,000. The contractor adds S$18,000 for variations and has already received S$100,000 in progress payments. Its final claim is therefore S$38,000, excluding GST for simplicity.
The customer accepts S$8,000 of the variations but disputes the remaining S$10,000. Assuming there are no other deductions or retention conditions, S$28,000 of the claimed balance is not disputed on price. That does not automatically establish when it is legally payable, but it gives both parties a clearer starting point.
The contractor can ask the customer to confirm the accepted items and discuss payment of the undisputed amount while reviewing the disputed charges separately. This is more constructive than repeatedly sending the same S$38,000 invoice without addressing the customer’s objections.
An itemised reconciliation also helps management see whether the main obstacle is approval of additional work, an unresolved defect, a payment condition, or the customer’s ability to pay. Each requires a different response.
Reconstruct What Was Agreed for Each Variation
Renovation projects change as work progresses. Customers request different materials, additional storage, relocated fittings or extra power points. Some changes appear minor when discussed on site but create meaningful labour and material costs.
For each disputed variation, reconstruct the sequence of events. Identify the original scope, the requested change, who requested it, the quoted price, the approval received and the work completed. Link the relevant quotation, email, message, drawing and site photograph to the same item.
Evidence that work was performed answers only part of the question. A photograph of an upgraded countertop may show that it was installed, but it does not by itself establish that the customer agreed to the additional charge. Similarly, a supplier invoice establishes a cost to the contractor, without necessarily establishing the amount recoverable from the customer.
The identity of the person approving the change also matters. A site contact may coordinate access and design details without having authority to approve extra expenditure. Where authority or contractual entitlement is unclear, management may need legal advice before treating the claim as firmly established.
The purpose of this review is to replace competing recollections with a traceable account of what happened. It can also reveal where the contractor’s own communication left room for misunderstanding.
Separate Defects from Disagreements About Price
A customer may raise several objections in the same email, but they should not all be handled as one issue. A complaint about a scratched cabinet door is different from a claim that additional carpentry was never authorised.
Prepare a defect list that identifies the reported issue, the contractor’s assessment, the proposed action and the expected completion date. Record when access is offered, when work is carried out and whether the customer accepts the repair. Keep this record connected to, but distinct from, the variation schedule.
This allows the project manager to address workmanship concerns while the person responsible for commercial matters reviews disputed charges. It also reduces the risk of an informal promise being interpreted differently by each side. An agreement to inspect a defect should be documented accurately, without accidentally suggesting that every requested deduction has been accepted.
Where the customer proposes a reduction, ask for the amount and basis of the deduction. A specific claim can be assessed against the contract and project evidence. A general statement that the customer is unhappy provides little basis for determining an appropriate financial adjustment.
Review the Accounts Before Relying on the Reported Margin
Issuing the final invoice does not, by itself, establish the revenue that should appear in the accounts. Finance needs to consider the contractual rights, work performed and uncertainty surrounding the amount claimed.
The applicable Singapore financial reporting framework should be confirmed first. For companies applying SFRS(I) 15 or FRS 115, relevant considerations can include contract modifications, the amount the business expects to be entitled to, and limits on recognising uncertain consideration. A contractor should not assume that every disputed variation qualifies as revenue simply because it has been billed.
Neither should management assume that every customer objection requires the entire invoice to be reversed. The assessment depends on the facts. A well-supported claim for approved work presents a different situation from an additional charge introduced only when the final invoice was prepared.
Give finance the underlying correspondence and variation records, together with the project manager’s explanation. A ledger entry labelled “final payment outstanding” conceals information that may be essential to assessing the balance.
This review is particularly important near the reporting date. Management should understand which project margins depend on unresolved claims before relying on those margins to assess performance or commit funds to the next job.
Distinguish a Pricing Dispute from a Collection Risk
There are two separate questions to consider: what amount the contractor is entitled to receive, and how much of a valid amount it expects to collect.
If the customer disputes whether an extra charge was agreed, the issue may affect the transaction price and revenue assessment. If the customer accepts the bill but cannot pay because its business is struggling, the concern is more directly about recoverability. Both issues can exist on the same project.
For companies applying SFRS(I) 9 or FRS 109, relevant receivables and contract assets are subject to expected credit loss requirements. Finance should assess the available evidence rather than wait indefinitely for a customer to formally refuse payment.
Practical information includes payment history, broken instalment promises, correspondence about financial difficulties and receipts after the reporting date. The length of time a balance has been outstanding is useful, but it should be considered alongside the circumstances.
Keeping these assessments distinct helps avoid using a generic bad-debt adjustment to conceal an unsupported charge. It also prevents a valid claim from being treated as fully collectible simply because the paperwork is strong.
Update the Cash Forecast While Discussions Continue
Even a claim supported by good records may take time to resolve. The contractor still needs to fund payroll, supplier payments and work on other sites during that period.
In the hypothetical project, management should avoid treating the entire S$38,000 claim as available cash next week. It could instead prepare scenarios showing different collection amounts and dates. One might assume receipt of the undisputed S$28,000 first, with the remaining S$10,000 dependent on later agreement. Another might reflect a delay in receiving both amounts.
These are planning assumptions, rather than predictions or accounting conclusions. Their value is in showing whether the business can meet its commitments if collection takes longer than hoped.
Include any further cash outflows needed to close the project, such as rectification labour or replacement materials. A job can require additional spending after the team considers the main work complete. Recording those expected payments gives management a more useful view of the project’s remaining cash demands.
Make Any Settlement Specific
A commercial settlement may be sensible when further negotiation would consume time and resources without a clear benefit. However, the decision should be based on the evidence, the amount involved, the likely collection outcome and the cost of continuing the dispute.
Avoid leaving the arrangement as a loose promise to “take something off the bill.” Set out the agreed adjustment, the revised balance, the payment dates and any remaining work. Make clear which disputed items the arrangement addresses, and obtain appropriate review where the wording affects legal rights.
Finance should receive the approved agreement so that the accounting records and customer statement reflect it correctly. Any credit note or other adjustment should be assessed for its accounting and tax consequences rather than issued merely to remove an uncomfortable overdue balance.
If a payment plan is agreed, assign someone to monitor it. A signed settlement can still leave the business exposed if missed instalments pass unnoticed or the customer believes further deductions remain open for discussion.
Close the Approval Gaps Before the Next Project
The most useful process changes usually follow the point where the disagreement began. If pricing was unclear, improve variation quotations. If approvals came from the wrong person, confirm authorised contacts at the start of the project. If records were scattered across personal phones, introduce a shared project file.
A variation record should describe the work, the price or agreed pricing basis, any effect on timing and the approval received. The customer should be able to understand what is changing before the contractor commits resources wherever practicable.
Urgent site decisions need a defined process too. When immediate written approval is impractical, record the instruction promptly, escalate it to the appropriate person and seek confirmation. This improves the evidence available, although it does not guarantee that the charge will be enforceable.
Review outstanding variations throughout the project. A short discussion between project management and finance can identify work that has been completed but remains unpriced, unapproved or unbilled. Resolving these gaps while the details are fresh is generally easier than reconstructing them after handover.
Give Financial Closure the Same Attention as Site Handover
A completed renovation should have a clear financial closing process. That means reconciling the contract and variations, reviewing unresolved defects, confirming remaining supplier costs and documenting the status of the customer balance.
The owner does not need to personally chase every document. However, someone should be accountable for bringing the project manager’s records, customer correspondence and finance ledger together. Without that coordination, each team may hold a different version of the project’s outcome.
Credon provides accounting and audit services that can support businesses in reviewing the financial reporting implications of outstanding project balances. Where a final bill remains disputed, a useful starting point is a documented breakdown of the claim and the evidence supporting each component.
That gives management a firmer basis for deciding what to pursue, what to negotiate and what needs reassessment in the accounts. It also turns a difficult project close into practical improvements for the next contract.
