How do coupons get added to MRR?
The MRR does not include the coupon and increases every time an unbilled charge is deleted or updates are made to an ongoing subscription without proration.
In case you do not want MRR to take a one-time coupon into the calculation, please disable one-time coupons to be included in the MRR (As part of your flexible MRR settings) so that they aren't included in the calculation.
Example 1:
Step 1: Let's assume that the subscription contains the following items and are pushed to unbilled charges:
Plan - $100
Add on - $100 * 3MRR at step 1: (100 + 300) - 50% = $200. The coupon is included here because an unbilled charge is present with the coupon applied.
Step 2: Delete the unbilled charges
MRR at step 2: $400. The coupon is not included here because there is no invoice or unbilled charge present with the coupon applied.
Example 2:
Step 1: Let's assume that the subscription contains the following items and are pushed to unbilled charges:
Plan - $100
Add on - $100 * 3MRR at step 1: (100 + 300) - 50% = $200. The coupon is included here because an unbilled charge is present with the coupon applied.
Step 2: Delete the unbilled charge
MRR at step 2: $400. The coupon is not included here because there is no invoice or unbilled charge present with the coupon applied.
Step 3: Change subscription -> apply proration and push the changes to unbilled charges (OR)
Plan - $200
Add on - $100 * 3MRR at step 3: (200 + 300) - 50% = $250. The coupon is included here because an unbilled charge is present with the coupon applied after the subscription update action.
Step 4: Change subscription -> do not apply proration and push the changes to un-billed charges
MRR at step 4: 200 + 300 = $500. The coupon is not included because there is no unbilled charge or invoice present with the coupon applied.
In conclusion, the MRR does not include the coupon and increases every time an unbilled charge is deleted or updates are made to an ongoing subscription without proration.
