Marine parts retail: customer records (vessel type, typical purchases), parts catalog (prop, shaft, impeller, zinc, hardware by manufacturer), multi-location inventory, POS sales with markup tracking. Special-order workflow for hard-to-find parts. Vendor pricing + lead times. Counter + phone + online channels. For 1-5 shop chandlery operators.
Per customer: vessel (make, model, year, engine), typical parts purchases, preferred payment terms, service history. Anniversary reminders (zinc change, impeller replacement) bring them back.
Per part: manufacturer (Mercury, Yamaha, Volvo Penta, Yanmar, generic), part #, compatibility (which engines), SKU, on-hand qty, cost + retail. Cross-reference supersession ("old #XYZ replaced by #ABC").
Per SKU × location: on-hand qty, aisle/bin. Transfer between stores. Reorder points. Cycle count schedule. Dead-stock reports (haven't sold in 90 days — discount or return to vendor).
Counter sales. Phone orders with customer card-on-file. Web order fulfillment. Per-sale: customer, items, discounts, tax, payment method. Daily close-out. Sales tax + B&O export for accountant.
Customer asks for hard-to-find part. Order tracking (vendor, lead time, deposit). Customer notified on arrival. Shoplift-safe deposit workflow (50% at order, balance at pickup).
Flask + session auth. Customer list, purchase history, vendor pricing stay yours. Not fed into a marine-industry SaaS 'retail benchmark' report.
