Why ecommerce fulfillment needs a structured operation
Statistics Canada measured $5.086 billion in monthly Canadian retail ecommerce sales in April 2026. Behind that volume, every order still has to be received, located, picked, packed, handed to the right carrier, and monitored through delivery. For a growing brand, the requirement is therefore larger than finding storage space. Inventory, preparation rules, packaging, timing, and exceptions need to work as one system. Tandem combines a local team, ShipHero, and the Tandem app so fulfillment remains visible and decisions can rely on operational data instead of disconnected follow-ups.
A useful comparison goes beyond the price per order. Ask how the partner receives inventory, maintains accurate quantities, applies your brand rules, and communicates when a parcel or order leaves the normal operating flow.
Data and integrations
Confirm how Shopify, WooCommerce, Amazon, or other channels feed the WMS. Orders, inventory, statuses, and tracking numbers should move without manual re-entry. ShipHero documents distinct workflows for inventory and order fulfillment.
Receiving and accuracy
Clarify requirements for SKUs, barcodes, quantities, appointments, and receiving discrepancies. Inventory that is poorly identified on arrival creates downstream errors even when picking is fast.
Fulfillment rules
Document cutoffs, priorities, materials, inserts, fragile products, lots, and special orders. A 24h or weekend objective should be connected to precise conditions and your expected volume profile.
Visibility and exceptions
Ask which dashboards, alerts, and owners will help when an order is blocked. The useful measure is not only how many parcels shipped, but how quickly a problem becomes visible and actionable.
What Tandem confirms during evaluation
Before launch, we clarify product profiles, normal and peak volumes, destinations, sales channels, packaging rules, and service expectations. The quote then identifies the applicable conditions for storage, receiving, fulfillment, materials, shipping, minimums, and special handling. Statements such as 24h shipping, 7-day operations, or shipping rates from $4 remain subject to cutoff, parcel profile, destination, volume, and carrier. This evaluation prevents a marketing promise from becoming an ambiguous operating expectation.
