VAT on Receipts
What it's for: the VAT figure your VAT return actually needs on a cash basis — VAT contained in money you've received, not money you've billed. Your accrual-basis VAT (VAT on invoices raised) is unaffected and available elsewhere as before; this report exists because cash-basis VAT could not be produced before.
Shows, by payment date: matter, invoice number, profit costs net and VAT, disbursements net and VAT, and total VAT. Totals: VAT on profit costs, VAT on disbursements, total VAT received.
Which basis (cash or accrual) your firm actually files under is between your firm and its accountant — CaseConnect produces both figures and does not choose for you.
