Check in this order

  1. 1

    Where it is applied

    Saved codes are applied by you in the quote or invoice builder (Billing amount → Add Discount). Customers do not type codes on the pay page.

  2. 2

    Code exists and is active

    Settings → Discounts: the code must exist, be active, and match exactly (no spaces).

  3. 3

    Already sent

    A sent invoice's total is fixed. Add the discount with a credit note (Credit Notes & Refunds) or edit and resend if unpaid.

  4. 4

    Cash discount

    That is the separate Settings → Billing → Offer a cash discount switch; it only applies when you record a full cash or check payment with Apply cash discount ticked.

  5. 5

    Member discount

    Comes from an active service agreement with Member discount set; it applies automatically to that customer's new quotes and invoices, not via a code.
