One business record, one product list, one set of orders. The public shop and the till read the same database.
Templates, branding, cart, checkout, and a public /store/slug URL. Subdomains wait on wildcard DNS.
Products you add in inventory can be listed on the shop. Sales write stock movements.
Counter sales with the same products. Cash drawer and staff sign-in for the floor.
Each merchant stores their own Paynow integration. Platform subscription billing is separate.
Quotes become invoices without retyping. Not a second commerce engine.
Walk-in customers on the till. Guest checkout on the shop, optional shopper accounts.
Sales, profit, and who owes you — from real records, not sample charts.
