Where this came from (Reddit)

Small businesses drown in supplier invoices and manual data entry.

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 serve them.

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. Give each client a forwarding email address.
  2. Have AI read vendor, date, items, tax and total.
  3. Create a draft bill in QuickBooks or Xero through their official API.
  4. Flag anything unusual for the owner to check.
  5. Charge monthly by Stripe based on volume.
  6. Partner with bookkeepers and find clients through local business groups.

Ready-to-copy prompt

Here is an invoice: [paste]. Return vendor, invoice number, date, due date, line items, tax and total as JSON, and flag anything that looks wrong.
