Quick answer
Prepare the contract, quote, purchase order, invoices, proof of payment, delivery records, complaint messages, photos, repair quotes and a simple loss calculation. The lawyer needs to prove what was agreed, what went wrong, and what loss followed.
Key takeaways
- Prepare the contract, quote, purchase order, invoices, proof of payment, delivery records, complaint messages, photos, repair quotes and a simple loss calculation. The lawyer needs to prove what was agreed, what went wrong, and what loss followed.
- Create a folder with four sections: agreement, performance, complaint and loss. The agreement section has the quote, contract and order. The performance section has delivery notes, job cards and proof of work. The complaint section has messages and photos. The loss section has invoices, replacement costs and business impact.
- Costs depend on whether the lawyer must review documents, write a demand, negotiate, draft settlement terms, or issue court papers. A good document bundle usually reduces the time spent reconstructing the dispute.

Why this situation happens
Supplier disputes often become messy because the agreement is spread across emails, WhatsApps, invoices and phone calls. One person remembers a deadline. The other points to a term in the quote. One says the goods were defective. The other says they were accepted. Documents bring the dispute back to proof.
Legal explanation
Some supplier disputes may involve consumer rights under the Consumer Protection Act and complaint routes such as the National Consumer Commission or Consumer Goods and Services Ombud. Other disputes are ordinary contract or commercial disputes where the written agreement and conduct of the parties carry the case.
What to do next
Create a folder with four sections: agreement, performance, complaint and loss. The agreement section has the quote, contract and order. The performance section has delivery notes, job cards and proof of work. The complaint section has messages and photos. The loss section has invoices, replacement costs and business impact.
Do not send a final demand until the documents have been checked. The wrong demand can overstate the claim or admit a weak point.
Costs and timeframes
Costs depend on whether the lawyer must review documents, write a demand, negotiate, draft settlement terms, or issue court papers. A good document bundle usually reduces the time spent reconstructing the dispute.
FAQs
What if the agreement was only by WhatsApp?
Export or screenshot the full conversation and keep payment, delivery and performance records. Do not edit the message trail.
Should I calculate my losses before seeing a lawyer?
Yes, but keep it separate from the documents. Mark which losses are paid, estimated, disputed or future losses.
Do photos help?
Photos can help where goods, workmanship, delivery or defects are disputed. Keep original files where possible.
