1. Problem & Market

Every company that grows beyond a couple of employees needs a lightweight way to:

• let staff request to buy something,
• route that request to the budget-owner,
• store the PO / receipt,
• forward the data to accounting.
  SMBs either (a) wing it in Slack/Sheets/Email or (b) buy heavy, expensive suites (Coupa, Netsuite, SAP Concur). A simple web app that plugs into Slack/Email and exports CSV to Xero/QB hits the ‘missing-middle’.

2. Evidence of people asking

• HackerNews thread you linked – 80+ upvotes, founders & finance people chiming in with “I built my own Google Form for this”, “We pay $500/mo for Precoro, would love cheaper”.
• r/sysadmin: multiple posts like “Solution for IT purchase orders – tracking, approvals, etc?” (May 2022).
• r/BusinessCentral365 post “Efficient PR to PO Conversion with Purchase Requisition Software” (July 2023).
  These are organic “pull” signals, not vendor marketing.
