A pick-and-pack rate is one line in a warehouse comparison. The founder needs the cost of executing the required workflow and confidence that the provider can perform it.
Quote the same work
Give each candidate the same order file, SKU dimensions, expected inventory, inbound shipment pattern and channel mix. Price receiving, storage, order handling, packaging, account-specific preparation, returns, reporting and integration. Add contractual minimums, project charges and exit terms where applicable.
Three fictional providers quote $2.10, $2.45 and $2.85 for a simplified pick task. Those numbers are teaching examples, not observed market prices. They establish no total-cost winner because the service baskets and execution performance have not yet been compared.
Avoid comparing one quote that includes materials with another that excludes them. Check the rate's unit: per order, unit, carton, pallet, hour or month. Match volumes and measurement periods.
Test the workflow before committing
Use a sample retail order and the actual account's approved requirements. Ask the candidate to describe item setup, stock reservation, preparation, documentation, shipment and confirmation. Then test critical steps with representative goods where practical.
Agree how inventory accuracy and dispatch performance will be measured, who investigates an error and which records support a dispute. Confirm whether special preparation is performed in-house or by another provider and how the handoff is controlled.
Model exceptions without inventing an error rate
If comparable performance evidence exists, include it. Otherwise build explicitly hypothetical exception scenarios instead of portraying an assumed chargeback rate as observed fact. Record receiving delays, rework and missing stock as operational risks to resolve in the pilot.
Choose a provider whose capability and full cost fit the launch. A higher pick rate can be justified by verified value; it is not proof of quality by itself.
