Processing Customer Transactions
Sales documents, invoices, credit notes, discounts, VAT, books of prime entry and the allocation of receipts from credit customers.
How to study AAT Level 2
Follow each transaction from its evidence to the correct record, preserve double entry, reconcile the result and communicate what the information means in its business context.
Core concepts
Concept 1
Customer transactions move from quotation or order through delivery, invoice or credit note, daybook entry and the customer account.
Exam cue: Read the commercial document sequence before selecting the record or calculating the amount.
Concept 2
Invoice and credit-note totals require the correct treatment of quantity, trade or prompt-payment terms, net amount and VAT.
Exam cue: Calculate the net amount first, then apply the required VAT treatment and reconcile to the total.
Concept 3
Receipts must be matched to the correct customer, invoice, credit note or opening balance, with discrepancies investigated rather than forced through.
Exam cue: Compare the remittance advice with the customer account before allocating a receipt.
