How to record payment or leave a vendor balance due

In this guide: Record how a purchase was paid or keep the amount due on the vendor account.
Record a paid purchase
Review the purchase total and select Save Purchase.
Choose the payment source, such as an external payment or the register when allowed.
Select the configured purchase payment method.
Enter a payment reference when useful.
Confirm the amount and select Pay & Save.
Leave a balance due
Select the vendor before saving.
Choose the option that keeps the purchase open or records the allowed unpaid balance.
Save the purchase and verify the remaining due amount on the saved record.
Why the vendor matters
A vendor is required when a balance remains due or the purchase is consignment, because RepairNest POS needs to know which supplier account owns the balance. A fully paid purchase may be saved without a vendor, but adding one improves supplier history and invoice lookup.
Vendor statements, balance reconciliation, and payables will be covered in a separate Vendor Accounts guide.
