HAC-97: Offer a cheaper plan in the cancel flow - #1264
Conversation
Add a downgrade retention offer next to the pause: Pro+ cancellers are offered Pro and Ultra cancellers Pro+ when they cite price, low usage, or other. Accepting applies the plan change immediately with Stripe proration credit through the existing tier-change path, records the acceptance on the subscription and the cancellation row, and reloads entitlements. The offer step now lists eligible offers as selectable options with a single primary action, gated by the hac-97-downgrade-offer flag with the same fail-closed flag handling and evaluation telemetry as the pause.

- Around line 434-440: Update handleOpenChange to call
reloadWithEntitlementRefresh whenever the dialog closes after a downgrade,
regardless of whether closure comes from the Done button, header close button,
or dismissal. Then simplify handleOfferResultDone to only close the dialog
through handleOpenChange(false), avoiding duplicate refresh logic.
In `@convex/cancellationReasons.ts`:
- Around line 222-223: Update the cancellation-state logic around the status
update and retention offer handling so a different offer is rejected once an
offer has been accepted or after the row leaves "started", while repeating the
same offer remains idempotent. Preserve the retained status and accepted offer
consistently, and add tests covering both offer-ordering cases.
In `@lib/actions/downgrade-subscription.ts`:
- Line 135: Update the Stripe subscription downgrade flow using payment_behavior
and the surrounding downgraded/retentionDowngradeApplied handling so a
pending_update is not treated as applied. Either require immediate completion
with error_if_incomplete, or detect the pending state and return a
confirmation-required result without emitting applied records until the webhook
confirms the item change.
In `@lib/billing/client.ts`:
- Around line 147-157: Update the downgrade flow anchored by
downgradeSubscription and the server-side downgrade action to pass a stable
idempotency key, derived from the subscription and offer acceptance, to
stripe.subscriptions.update. Ensure retried requests reuse the same key while
preserving the existing downgrade behavior.
In `@lib/billing/retention-offer-evaluation.ts`:
- Around line 89-93: Guard the Stripe price lookup inside
resolveDowngradeTargetPrice so transient stripe.prices.list failures fail closed
for the downgrade offer by returning its existing no-target result. Preserve
evaluateRetentionOffersForUser’s ability to continue evaluating and display an
eligible pause offer when this lookup fails.
- Around line 121-125: Update the credit calculation in the preview evaluation
flow to retrieve all paginated preview lines, then sum only negative lines whose
parent subscription item details mark them as proration and whose subscription
item matches args.subscription.itemId. Preserve the existing dollar conversion
and rounding when assigning target.proratedCreditDollars.

The user keeps the current plan until the paid-through date and renews on the cheaper price with no proration or credit. A Subscription Schedule holds the change; cancel, pause, keep, and plan-change paths release it first, and account settings shows the pending switch with a way to keep the current plan.

Summary
Adds a downgrade retention offer next to the pause (Linear: HAC-97). Pro+ monthly cancellers are offered Pro ($25), Ultra cancellers are offered Pro+ ($60), when their reason is "too expensive", "not using it enough", or "other".
Why this shape: of Pro+/Ultra cancellers who came back on their own in the last 180 days, 14 of 19 Pro+ returnees chose Pro and 5 of 8 Ultra returnees chose Pro+. These cancellers are heavy users (median ~200 agent runs, two thirds hit a usage limit), so a cheaper tier keeps the MRR and the relationship at zero give-back, versus a discount that costs $60–180 per acceptor. Analysis in HAC-97.
