What to do when a customer disputes your electrical invoice
Collect the facts, separate the disputed amount and give the response an owner. A practical admin routine for an electrical business.
Get the actual question before sending another reminder
A customer replies, “That invoice is wrong.” Sending the same overdue reminder again will not tell you what they are questioning. Ask which item they mean and what they believe was agreed. Record their words alongside the invoice reference.
Treat a complaint about the work differently from a missing purchase order, an unrecognised extra or a payment already made. One may need technical review; another may be solved by supplying a document. The person handling the inbox should identify the issue and bring it to the right owner.
Pause the ordinary automatic chase for the disputed item while you arrange a review. That is an admin step, not a decision that the debt is cancelled or that every other amount is payable.
Build a short evidence file
Find the accepted quote version, the scope, any approved changes, completion notes, the invoice and the relevant messages. Keep the sequence intact. If an approval is missing, mark it missing. Do not rewrite an old quote to make it look as though the extra was there from the start.
Keep facts and recollections separate. A dated message saying “please add the two sockets at the price quoted” is different from a note written today saying you remember a conversation. Both may be relevant, but they are different kinds of record.
- Customer and job reference; invoice number and date.
- The exact item or amount questioned, and the reason given.
- Where the original agreement and change records are held.
- Evidence still missing, who will find it and when.
- Who may decide the price, technical response or correction.
Separate the amounts without deciding the legal answer
Use a disputed-amount column so you can see the question clearly. An illustrative £1,240 invoice might include an £180 extra the customer questions, leaving £1,060 outside that particular query. This calculation records the issue; it does not prove the £1,060 is legally due or that the customer accepts it. Ask for their position rather than assuming.
Check receipts and credit notes as well. If £500 has already arrived, record it against the right invoice before talking about a remaining balance. Preserve the original invoice and the accounting trail if a correction is authorised; ask your accountant how to record it.
A disputed debt is outside the simple business late-payment estimator in the free pack. Do not use its result as a threat or as an automatic charge while an entitlement is uncertain.
Acknowledge it and give a realistic response date
A short acknowledgement can stop the conversation becoming a pile of arguments. Name the item you are checking, the person doing the review and when you expect to respond. If you need access to inspect the work, explain the next arrangement separately. Do not promise the problem is fixed before the responsible electrician has reviewed it.
Suggested acknowledgement Hi [name], thanks for explaining the query on invoice [number]. I understand you are questioning [specific item]. I will check the accepted quote, change record and job notes with [responsible person] and come back to you by [realistic date]. If there is another item you want us to review, please send its details here. Thanks, [name].
Choose the escalation route for the actual contract
Consumer complaints, business debts and construction contracts can need different advice. GOV.UK lists options such as mediation and a court claim, with different processes across the UK. Before making a formal demand or starting a claim, check the applicable procedure and deadlines with a qualified adviser.
The Small Business Commissioner has a limited investigation remit, principally smaller businesses dealing with larger private businesses. Its FAQs exclude construction-sector complaints and work under the Construction Act. Do not assume an electrical contractor can use that complaint scheme for a construction payment dispute.
Keep approaching contractual notice deadlines deliberately even while a conversation is friendly. This article does not set legal response periods or replace a contract review. An admin response date you choose is a working commitment, not a universal legal deadline.
Close the loop when the decision is made
Record the agreed outcome, who approved it and what was sent to the customer. That may be an explanation, a corrected document, an agreed remedy or a referral for advice. Update the payment record only from the actual outcome. A discussion is not a receipt.
Use the unpaid list in the Invoice and Payment Pack for the next action and the complaint record in the Admin Toolkit for the factual review. Stacked Out can organise that file and keep the correspondence moving. The owner retains price decisions, and technical matters remain with the responsible electrician. Start by marking one unresolved query with a named decision owner.
