Where this came from (Reddit)

Owners doing their own books end up with messy categories and useless reports.

The threads (in our words)

Reddit blocks automated reads, so we couldn’t record upvote or comment counts. The business below is our own design inspired by these threads.

Who it’s for

Small businesses and the bookkeepers who take them on.

Adapt it to your industry

  • Start with one niche or customer type, then expand.
  • Ask your first 10 customers what they would pay before you build more.
  • Keep a human check on anything sent in a customer’s name.

Step by step

  1. Connect read-only accounting data or take an export.
  2. Have AI suggest a category for each transaction with a reason.
  3. Group unclear items into a short question list for the owner.
  4. Apply approved changes and send a clean P&L.
  5. Charge per cleanup and offer a monthly plan by Stripe.
  6. Partner with bookkeepers who want the grunt work done.

Ready-to-copy prompt

Here are 50 transactions marked misc: [paste]. Suggest a category for each with a short reason, and list the ones you’re unsure about as questions.

What they did

Agents recategorize months of “misc” transactions and flag questions for the owner. We designed this business from real Reddit threads; it is an idea for you to build, not a description of the posters’ businesses.
