Small shops with steady sales still run out of cash before month end
Pattaya Mail (June 2026) says cash flow, not sales, is the main SME problem: owners report dwindling reserves, delayed payments to suppliers, trouble funding stock, and use of personal credit cards. Higher fuel prices raised transport and raw material costs, and the owner must either raise prices or absorb the cost.

5 ways to tackle it
Hardware and sensors
Cash Light: a lamp on the shelf that turns green, amber or red with days of cash left
The owner photographs slips and bills once a day. A small lamp shows how many days the cash covers against the bills coming due: green for 20+, amber for 7 to 20, red below 7. It makes the squeeze visible a week earlier than the bank balance does.

Dead Stock Finder: photograph your shelves and see the cash stuck in slow items
The owner photographs each shelf. Claude vision counts items and compares with the sales sheet, listing what has not sold in 60 days and the baht tied up in it. It suggests a bundle price or a supplier return so the money comes back.

Payment Caller: an agent that phones customers who owe the shop and asks politely
The owner gives the agent a list of overdue invoices. It calls each customer in polite Thai, asks for a date, logs the promise, and calls again if the date passes. The owner stops spending evenings awkwardly asking for money.

Bill Pile Sorter: photo of the bill pile becomes a one-page pay-in-this-order sheet
The owner dumps the supplier bills on the table and takes one photo. Claude vision reads the amounts, due dates and late fees, and prints an A4 sheet: pay these two now, ask these three for 7 more days, with a ready-written request for each. Bills stop piling up unseen.

Group Order: three shops order together to reach supplier minimums and better terms
Neighbor shops add what they need to a shared basket on one page. The order hits the supplier's minimum, the price falls, and the group asks for 30-day terms together. Each shop's share and PromptPay QR is on one printed sheet.
