Launch week: every idea card is free.Get Pro

SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

Failed Payment Recovery Churn

Subscription businesses lose recurring revenue when failed payments silently churn customers because default retries and dunning emails fail to recover them.

In their words

how are you dealing with failed subscription payments (expired cards, insufficient funds, etc.)?

r/SaaS on Reddit

Often cards expire or some reason Stripe turns off automatic payments. Then I randomly check every so often and see a lot of unpaid.

r/stripe on Reddit

we were losing revenue for months before I noticed - Stripe wasn't throwing errors, payments were just silently failing

r/microsaas on Reddit

I'm so tired of having to have failed payment email flows with several branches because I'm checking if they're shop pay or not

r/shopify on Reddit

I get to the checkout line and swipe my card....IT EXPIRED YESTERDAY!!!

We were re-charging customers when the original charge had cleared but our system hadn't gotten the confirmation in time.

They sign up for the trial, and their cards decline at the end, most of the trials end up declining.

r/SaaS on Reddit

I often have trials that turn are cancelled due to billing errors

r/androiddev on Reddit

r/smallbusinessuk on Reddit

Do you know of any EU payment processor that supports recurring payments like a SaaS would need (subscriptions, subscription state tracking, automatic retries of failed payments)?

Hacker News

  • r/stripe
  • r/microsaas
  • r/micro_saas
  • r/EntrepreneurRideAlong
  • r/gohighlevel
  • r/SideProject
  • r/smallbusinessowner

Tools they use today

  • Stripe
  • Razorpay
  • Paddle
  • PaymentKit
  • GoHighLevel
  • PayPal
  • Shopify
  • Mercado Pago

Why those fall short

  • no pre-renewal reminder or self-serve refund flow
  • system lets them try as many times as they want
  • failed Order closes permanently, no retry on same order
  • No expiry warning; digital card not accepted in most stores
  • edge cases still turn into operational work
