Invoice payment checker
Calculate contract deductions, VAT, payments and the new due amount.
Discount and advance recovery reduce the amount subject to VAT. T&C and retention percentages are calculated from the total contract value (A). Lines with a zero value are hidden from the summary.
Invoice summary (A–J)
The breakdown updates when you calculate.
Confirm your contract's deduction bases and VAT treatment before using this for an actual payment certificate.
How J is calculated
C = A − A1 (discount) − B D = C × VAT rate E = C + D
F = A × T&C % G = A × Retention %
J = E − F − G − H − I
