Point of sale and retail connectors for Claude and ChatGPT.

Point of sale connectors read what the register saw: sales by day, top items, stock on hand and the customers behind them. A shop owner can ask how Saturday compared to last Saturday and get the answer from the real numbers.

Inventory and catalog changes are writes. Prefer connectors that ask before they change a price or a count.
