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.

Manual Expense Tracking

Teams and individuals struggle with slow, error-prone manual expense tracking, receipt chasing, and reconciliation across scattered systems.

In their words

Once we had Jakarta staff putting personal cards down for client dinners in IDR, waiting three weeks for reimbursement to clear at whatever month-end FX rate landed, the credibility damage was immediate.

transactions that have been recurring for YEARS and correctly categorized are now seemingly randomly categorized.

r/MonarchMoney on Reddit

In reality, I would take my portfolio balance, and how many years I had left in my plan, into account when deciding how much to spend.

r/projectionlab on Reddit

I could for example have Cowork generate a weekly analysis of spend by category, by vendor, or against budget

r/microsoft_365_copilot on Reddit

We still chase a few repeat offenders though lol.

r/Ramp on Reddit

our controller manually assigns transactions to the appropriate projects. It works, but it's very time-consuming

r/Ramp on Reddit

the actual day-to-day opex and expense forecasting still completely relies on massive, clunky Excel workbooks passed around like hot potatoes

r/FPandA on Reddit

The expectation is that we call for permission, use our own money, and put it on a monthly reimbursement form with receipts.

r/socialwork on Reddit

it seems that Quickbooks has moved towards AI categorization which is often incorrect and takes longer than whatever older algorithm they used

r/QuickBooks on Reddit

It’s the budget that you didn’t even receive from the PI until 4:37pm that has too many errors to fix

r/ResearchAdmin on Reddit

once you add another contractor, another bank account and a business credit card, the spreadsheet starts getting annoying fast

r/Entrepreneur on Reddit

flights go on personal cards and then they wait on us, our cycle is a monthly batch

r/nonprofit on Reddit

I have thousands of people on an org. I had to go through every page to extract the top spenders.

You'd be surprised at how quickly edge cases start to pile up when an accounting system makes contact with the real world.

Why those fall short

  • ERPs built for governance, not flexible ad-hoc analysis; uploads return wrong numbers
  • Claude needs hand-holding, hits token limits, and lacks receipt matching
  • Copilot Premium only searches; no iteration or reuse of prior results
  • cards show who spent but do not prevent the wrong purchase
  • AI categorization often incorrect and slower than older algorithm
