Parcel Sorting Solutions by Operation

One sorting system, mapped differently for each job: by route at a delivery station, by carrier in a warehouse, by ZIP for USPS injection.

Quick answer: SortLease provides SortLease S15 parcel sorters for delivery service partners, couriers and regional carriers, warehouses and 3PLs, and shippers injecting at USPS delivery units. Each tier or line is rated at up to 3,600 parcels per hour. Pay per parcel from $0.10 at your site or a shared hub, or buy a system quoted per configuration.

FAQ

Solutions Questions

Is it the same machine for every solution?

Yes. The SortLease S15 is configured per site; what changes is how chutes are mapped (route, carrier, ZIP) and whether it's vertical or flat.

Do I have to buy equipment?

No. Pay-per-parcel pricing from $0.10 means SortLease installs, operates and maintains the sorter. Buying a system is also an option.

Where do you work?

Anywhere in the continental U.S. See locations.
