Odoo POS turns physical stores into channels that share products, prices, customers, and inventory with the rest of Odoo — while cashiers need speed, reliability, and clear exception paths.
This pillar focuses on business workflows and implementation strategy: multi-store design, inventory truth, payments and fiscal considerations, offline resilience, and measurement. Hardware specifics stay conceptual, not a device catalog.
Retail, Logistics, Performance, and Shopify guides cover omnichannel, warehouse, peak-load, and ecommerce connectors. Cross-link them; do not rewrite those deep-dives here.
