The store is a data source
Most independent retailers still treat the POS as a cash drawer with a screen. It's actually the single most valuable data source in the business - every SKU, every basket, every repeat. When it's connected to a modern CRM, it becomes the fuel for every marketing dollar that follows.
We connect POS + email + SMS + local search into one loop: shopper visits, opts in for a receipt, gets a welcome series that references the exact category she bought, and comes back in three weeks because the right offer landed at the right moment.
