Project delivery

From business scenario to an approvable acceptance scope

Where retail terminal projects usually break

The terminal is selected before POS, payment, printer, scanner, or network requirements are verified
Order, payment, membership, and inventory statuses use different identifiers or timing
SDK, driver, and callback limitations are discovered after procurement
Pilot acceptance and multi-site rollout responsibilities are not written down

Delivery scope

Select POS, kiosk, handheld, display, and peripheral combinations by workflow
Map order, payment, member, inventory, refund, and exception events
Build or coordinate the required SDK layer, API adapter, or middleware
Run a pilot and prepare configuration, troubleshooting, and rollout checklists

Acceptance criteria to define

Transactions and status changes remain consistent across terminal and platform
SKU, inventory, and membership mappings pass agreed test cases
Reconnect, retry, duplicate-event, and operator exception rules work as documented
Logs, device identity, remote support, and handover materials are available

What we need to start

Store format, number of sites, device roles, and forecast quantity
Existing POS, ERP, membership, inventory, and ordering interfaces
Payment market, peripherals, network, security, and certification requirements
Pilot date, rollout sequence, ownership boundaries, and target acceptance date
