Why deposits help, and where they go wrong
Deposits of 20 to 30% are common in construction. Agree the amount in the quote and invoice it when the client approves. VAT becomes due when you invoice or receive payment.
Forgetting the deposit in the final account causes overbilling and a credit note. Deducting it incorrectly, such as VAT-inclusive instead of VAT-exclusive, distorts the VAT return. Unclear records also lead to disputes over what has already been paid.
