Platform capabilities you should provide

• Rate shopping for Canadian carriers and services
• Label generation and label storage
• Tracking events and status normalization
• Address validation and delivery checks
• Billing, invoices, and usage reporting

Recommended architecture

Build a dedicated carrier adapter for Flagship, then expose a clean API layer for your customers. This keeps your public API stable while you add more carriers later.

• API layer: authentication, quotas, versioning
• Carrier adapter: Flagship API client, error mapping
• Shipment service: labels, shipment lifecycle, documents
• Tracking service: event ingestion and webhooks
• Billing service: usage, plans, invoicing

Carrier mix for Canada

Most Canadian platforms need integration coverage for Canada Post, Purolator, UPS, and FedEx. Design your platform so you can add direct carrier accounts in the future.

ZyroByte specializes in building shipping and logistics SaaS platforms with carrier integrations such as FedEx, UPS, DHL, and Purolator.

MVP roadmap
