You receive a credit note from a supplier (purchase) 1. You receive a credit note from a supplier (purchase) When you receive a credit note from a supplier (purchase), it means the supplier owes you money. In accounting, a credit note reduces your initial purchase expense. 2. Negative debit values ​​for a purchase credit note (-€125.63): If you enter a negative amount as a debit in your purchase account (for example, 607 for "Purchases of Goods"), Sage Accounting will interpret this as a reduction in the expense. In principle, Sage is designed to handle these situations correctly. If the initial VAT was debited on the original purchase, then a negative amount as a debit for the purchase credit note will result in a corresponding VAT adjustment. 3. 19.6% VAT credited in purchases: If Sage credits the VAT (for example, 44566 for "Deductible VAT on Other Goods and Services"), this is generally the correct way to handle it. A VAT credit on a purchase receipt means that you reduce the VAT you initially deducted. In other words, you "repay" part of the VAT owed to you by the government.
