Quick answer
A useful sorter RFQ gives every bidder the same parcel data, peak definition, destination plan, layout constraints, interfaces, scope split and acceptance criteria, then requires suppliers to disclose assumptions and exclusions.
Use one controlled data pack
Send every bidder the same parcel profile, throughput definition, layout, destination plan, interface list and operating calendar. Mark which values are measured, forecast or provisional.
Provide sample data distributions rather than only minimum and maximum values. A representative parcel mix helps suppliers estimate induction, carrier loading and discharge behavior more realistically.
Define performance in operational terms
State whether throughput means inducted, identified, sorted or successfully discharged parcels. Define the sustained test duration, recirculation treatment, no-read handling and availability calculation.
Separate normal operating capacity from short mechanical maximums. Ask how the proposed layout performs when a destination is full or an induction station is unavailable.
Separate required, optional and local scope
Clarify equipment, controls, software, guarding, freight, unloading, installation, commissioning, training, documentation, spares, taxes and local building works. Ambiguous scope produces low headline prices followed by change orders.
For international projects, state who handles local certification, labor rules, permits, import formalities and after-sales response.
Require assumptions and exclusions
Ask each supplier to list the assumptions behind throughput, availability, labor, energy and expansion claims. Require deviations from the RFQ to be shown in one schedule rather than hidden throughout a proposal.
A compliant comparison table makes technical and commercial review faster and exposes where two offers solve different problems.
Compare lifecycle support
Evaluate remote support, local response, software ownership, diagnostic access, warranty exclusions, preventive maintenance and spare-parts lead times. Request a recommended commissioning and two-year operating spare-parts list.
Confirm the documentation and training languages needed by operators and maintenance teams.
Frequently asked questions
What information is essential in a parcel sorter RFQ?
Include the parcel profile, sustained peak flow, destinations, site layout, interfaces, scope split, local requirements and acceptance tests.
How should sorter bids be compared?
Normalize the operating assumptions, included scope and test criteria before comparing price or headline throughput.
Should spare parts be included in the RFQ?
Yes. Ask for commissioning spares, recommended operating spares, lead times and the proposed regional stocking model.
