Advance and final payment: two payments can belong to one purchase
By Erik Nilsen · Kroni2 min read
When a purchase is paid in two agreed parts, your child needs the full price and the amount already paid. The remaining payment is not another item price. This is a record for a hypothetical purchase rather than advice about borrowing or credit.
Three figures must agree
In an invented example, a personal order costs 80 units altogether. The agreement requires 30 when ordering and the remaining 50 later. Your child already has 80 set aside. These terms describe no actual seller.
After the first payment, 30 has been paid and 80 − 30 = 50 remains payable. After the second, total paid is 30 + 50 = 80 and the remainder is zero.
Adding the full price 80 to the advance 30 and remainder 50 would produce 160. That counts one purchase twice. The full price explains the payments rather than creating a third payment.
Record dated parts and their status
A practical snag is forgetting the advance when the final request arrives. Write “30 paid” with its date and check that confirmation shows the same 50 remaining. An estimate of the remainder does not prove the actual request.
If an adult arranges the purchase against an agreed virtual amount of 100, the family record could show 100 − 30 = 70 after the first settlement and 70 − 50 = 20 after the second. Do not also deduct 80 as another expense. Agree what each entry represents.
A changed final amount requires checking what was added or removed. Do not assume another price is automatically an arithmetic error or that an advance is always refundable.
Ask your family: “How much has actually been paid, and which part of the whole purchase remains?”
Carry the calculation into your family agreement
Kroni can keep track of your child's virtual balance. The app does not transfer money, so any actual purchase is paid for outside it. Agree on what you will record, then check the amount with your child afterwards. Do not deduct a possible cost as though the purchase had already happened. Read about allowance in Kroni.
