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.

Usage Billing Reconciliation

Companies struggle to accurately meter, rate, and reconcile usage-based and hybrid billing, causing revenue leakage, overcharges, and manual work.

In their words

Observium shouldn't be doing this given it has to be hacked to work and my boss and I are in agreement that new software is required.

r/networking on Reddit

the logic limitations for stripe are really starting to show

r/SaasDevelopers on Reddit

Great product, horrible billing/pricing experience right now.

r/MSSP on Reddit

Now it’s ~$2k/month in disputes, endless reconciliation, and administrative pain.

r/SmallMSP on Reddit

Requiring a 12-month commitment for anything beyond the measly 100 concurrent realtime sessions is impossible to scale for startups who usually have monthly subscribers and free trials.

r/speechtech on Reddit

we cannot figure out how to set it up to get monthly overage while maintaining quarterly commit charges

r/Netsuite on Reddit

I permanently deleted my AWS account 6 years ago. Amazon has been charging me $0.33 every month since. I have no way to stop it.

r/mildlyinfuriating on Reddit

Who is auditing the AWS billing code and line items to ensure this is actually correct?

r/aws on Reddit

the subscription model isn't that convincing so my users stay unsubsribed and just keep buying credits

r/SaaS on Reddit

Microsoft’s billing quantities and prices do not reconcile with Azure Metrics, our application-side API usage logs, or Microsoft’s own Retail Prices API.

r/AZURE on Reddit

he doesn't want to pay the bill because he's added six employees and four computers and that's higher than what he originally agreed to despite us very clearly showing and telling that this is a per user price Model

r/msp on Reddit

Billing logic looked perfect, created accounting chaos. pres, plan changes.

r/nocode on Reddit

No way to now if it was legitimate, if it is just burning tokens or agents doing the same work on loop

Hacker News

Stripe checkout is maybe 10% of "billing." The other 90% is UI state, org scoping, deduplication, empty states

Why those fall short

  • Support redirects to closed accounts; recurring charges survive card changes.
  • heavy users cost more than they paid, light users churned
  • Alerts go out on one channel; no follow-up email or banner on the same channel
  • Invoices show one line, no SKU or usage detail
  • Billing quantities and prices do not reconcile with metrics or logs
