When a customer disputes an invoice, the delay in resolving it can hurt your cash flow, reputation, and time. Handling the dispute appropriately makes a huge difference. Here’s how to resolve a disputed invoice in South Africa—step by step—and how ProInvoice helps you stay organised, professional, and paid.
Stay organized as you grow. Use ProInvoice to manage billing and client relationships with ease.
1. Acknowledge the Dispute Immediately
When a customer raises an issue, respond quickly. Send a message or call to say you’ve received their concern, you’re taking it seriously, and you’ll investigate. A prompt response shows professionalism and helps prevent escalation.
With ProInvoice, you can flag invoices under dispute in your records so your team knows not to treat them as ignored—keeping communication clear and tracked.
2. Gather All Relevant Documentation
Before replying further, collect everything that relates to the invoice:
- The original contract or service agreement
- Quotes, change orders, or amendments
- Proof of delivery or completion (emails, photos, client sign-offs)
- Previous correspondence about expectations
Using ProInvoice ensures your invoice records include relevant line items, dates, and described services—making it easier to cross-check details and back up your case.
3. Review the Invoice and Compare with Agreement
Check whether the invoice matches what was agreed:
- Did you deliver what was agreed (scope, quality, quantity)?
- Were prices, quantities, and dates correctly listed?
- Were any extras or changes communicated and accepted?
If you discover a genuine error, prepare to issue a corrected invoice or a credit note.
4. Communicate Findings Clearly & Professionally
Once you’ve reviewed, get back to the customer:
- Summarise what you found: what matches, what’s in dispute.
- If you find mistakes, admit them, explain, and show how you will correct.
- If you believe the invoice is correct, present your supporting documents— but do so respectfully and clearly.
With ProInvoice, you can resend or update invoices with notes clarifying what’s corrected or confirmed, so both sides have matching records.
5. Propose a Resolution
Depending on what you found, propose a fair solution:
- If there’s a legitimate mistake, correct it and issue a new invoice or refund or credit.
- If the customer’s complaint is based on misunderstanding, provide extra information or references (delivery proof, sign-off, scope).
- Sometimes compromise is necessary—offer a partial discount or extended payment terms to maintain goodwill.
6. Document the Outcome & Update Internal Processes
Once resolved:
- Confirm the agreement in writing (email or document) so both parties have it.
- Mark the invoice as resolved, adjusted, or withdrawn as appropriate.
- Track whether payments are made under the new terms.
Then reflect internally:
- Where did the error come from?
- How could you prevent similar disputes?
- Do you need clearer contracts, better record-keeping, more client check-ins?
ProInvoice helps by keeping all past invoices, versions, client information, and payment statuses organised—so you can review patterns and improve.
7. Maintain Professionalism & Preserve the Relationship
A dispute doesn’t have to become a lost client. Stay calm, be transparent, and avoid aggressive posturing. Showing that you’re reasonable and committed to resolving issues builds trust and often leads to repeat business.
