Display One-Time Coupons at Subscription Level in Admin

Problem Statement

Currently, one-time (duration = once) coupons applied at signup are not displayed on the subscription record in Pelcro Admin, even though:

• The discounted price is correctly applied, and

• There is a visible but empty “Coupon Code” field at the subscription level.

This creates confusion for Customer Service teams and limits subscription-level reporting and auditing.

User Story

As a Customer Service team member,
I want to clearly see the coupon code applied to a subscription directly in the Admin,
so that I can support customers, audit discounts, and report accurately.

Current Behavior (Expected but Limiting)

• Coupons with duration = once:

  • Shown on invoices only

  • Not shown on the subscription record

• Coupons with duration = forever:

  • Shown on both subscription and invoice

Expected / Desired Behavior

• Any coupon applied at signup — including one-time coupons — should be:

  • Visible on the subscription level in Admin
