Someone signs up for an AI writing tool, gets charged after a trial they thought they cancelled, and spends two weeks trying to reach support — eventually disputing the charge with their bank because it's the only path that actually works. This happens thousands of times a month across tools like Anyword, aiseo.ai, and Wordtune, and it ends in chargebacks that cost vendors $15–25 each plus churn that could have been prevented with a simple refund.

The gap exists because billing resolution requires touching both the subscription system and the payment processor, and most small SaaS vendors haven't built self-serve tooling for this — they handle it manually via support tickets. The user can't cancel mid-cycle cleanly, can't request a prorated refund, and can't see what they were charged for. So they either give up or dispute.

Complaints specifically call out: 'impossible to get a refund for the premium subscription,' 'billing/account issues despite support acknowledgment,' and 'took over a month to get the account made through a reseller.' These aren't edge cases — they're the most common post-sale friction points.

A standalone refund and account management layer that sits between the customer and the vendor's Stripe/Paddle account gives users a resolution path without opening a ticket. For vendors, every chargeback prevented is $20+ saved and a customer who might resubscribe. The need recurs every billing cycle.

What to build

Build a white-label self-serve billing portal that connects to Stripe or Paddle, lets subscribers view charges, request refunds within configurable vendor-set rules, pause subscriptions, and escalate to a human queue only when the automated path fails — embeddable in any SaaS product via a single script tag.

Where to start

Launch first for Paddle-based SaaS tools specifically, since Paddle's native buyer dashboard is weaker than Stripe's and complaints about refund inaccessibility are disproportionately higher — giving you a structural fit before expanding to Stripe.

The hard part

Vendors have to trust a third party with refund authority over their Stripe account, which is a significant security and financial control concern — the permission model and audit trail need to be airtight before any serious vendor will connect their live billing.

How it makes money

Monthly flat fee per vendor based on active subscriber count, plus an optional per-refund-processed fee that aligns incentives — vendors pay more only when the tool is handling volume.
