When the bill differs from your quote

Keep the quote, agreed scope, messages, invoices and any requested variations. Ask the provider to explain the difference in writing. Whether a payment or remedy is due depends on the agreement, work and applicable law.

Before paying a deposit

Ask for payment stages, cancellation terms and inclusions in writing. Check the rules for the location and type of work; this guide does not prescribe a universal deposit limit, dispute limit or cooling-off period.
