The thesis
Small teams often have a sales system and an accounting system while the purchasing work between them lives in spreadsheets, email and memory. LineNow's thesis is that this work deserves a shared operating record: demand, purchase orders, supplier changes and receipts connected through the next buying decision.
That is closed-loop procurement. It is a product direction, not a claim that other systems cannot buy goods or that every business should replace its ERP.
What the spreadsheet gets right
Spreadsheets are flexible, familiar and useful for calculation. A disciplined team can maintain an order guide, compare quotes and plan replenishment with them. The problem appears when several people need the current state of an order while the supplier changes it in another channel.
An initial PO asks for ten cases. An email confirms six this week and four later. The receiver accepts five. The invoice bills six. Each number can describe a real event, but the team needs to know which event it represents and who is resolving the difference.
A connected workflow preserves those facts. It does not edit them all to agree or treat a supplier's proposal as the buyer's acceptance.
Six design principles
1. Recommendations need explainable inputs
A proposed quantity should show usable stock, expected consumption, relevant incoming orders, lead time and supplier pack constraints. For recipe or BOM purchasing, item mapping, quantity and yield must be validated. Counts and adjustments reconcile what the demand signal cannot observe.
