Submit shipment data from WMS, OMS, ERP, or custom systems.
Retrieve eligible rates for enabled services.
Buy labels and store the result in BoslogShip records.

Use idempotent workflows for reliable retries where supported.
Keep wallet and shipment records auditable.

Workflow matrix

Workflow	Fit	Page evidence
Portal order	Single orders, support lookups, and teams that want manual review before purchase.	BoslogShip keeps the selected service, label, tracking number, status, and wallet charge on the shipment record.
Shopify order sync	Shopify merchants that need order import, product mapping, label creation, and tracking return.	The public Shopify workflow pages describe order sync, product mapping, rate comparison, label purchase, and tracking return.
CSV or Excel batch	Warehouse teams, marketplace sellers, and operators handling daily order files.	Batch upload validates rows before import and exports carrier, service, tracking, status, and price data after labels are created.
Open API	WMS, OMS, ERP, middleware, and custom systems that need automated rates and labels.	BoslogShip Open API uses the same client-facing rate logic as the portal for approved clients and enabled services.
