Outbound Parcel Sorting by Carrier for Warehouses and 3PLs

Split outbound parcels for UPS, FedEx, USPS and regional pickups automatically, instead of by hand at the end of every packing shift.

Quick answer: a SortLease S15 reads each parcel's label (barcodes and printed text, up to five sides) and diverts it to a chute mapped to a carrier, a service level, a USPS delivery unit or a mix. Each tier or line is rated at up to 3,600 parcels per hour. Warehouses can buy a system, quoted per configuration, or run it on pay-per-parcel pricing from $0.10. Installation takes 2–4 weeks.
How it works in a warehouse

From Packing Station to Carrier Pickup

1. Induct

Packed parcels go onto the line by hand or automatic induction.

2. Read

The optical system reads the carrier label: barcode and printed text, up to five sides.

3. Divert

An arm-type diverter moves each parcel into the chute for its carrier or service.

4. Hand off

Each carrier's parcels are staged together and ready when the truck arrives.

Sort plans

Map Chutes the Way You Ship

  • By carrier: UPS, FedEx, USPS, Amazon Shipping, regional carriers.
  • By service: ground, express, same-day.

  • Mixed: any combination, changed in software between shifts.

Fits the building you have

The SortLease S15 deploys line by line. Stack up to six tiers where floor space is short, or run lines side by side where you have room. It uses about 40% less energy than a cross-belt sorter (manufacturer data).

FAQ

Warehouse Sorting Questions

Can the sorter split parcels by carrier?

Yes. Chutes are mapped in software by carrier, by service level, by USPS delivery unit or ZIP, or a mix, and the plan can change between shifts.

What labels can it read?

The optical system reads barcodes and printed label text on up to five sides of each parcel.

How fast is it?

Each tier or line is rated at up to 3,600 parcels per hour; vertical systems stack up to six tiers for 21,600 per hour. Actual throughput depends on parcel mix, label quality and staffing.

Does it connect to our WMS or carrier systems?

The sorter assigns chutes from the label and your sort plan. Tell us what systems you use and we'll confirm what the site design needs.

Can we buy it rather than pay per parcel?

Yes. Warehouses can buy a system, quoted per configuration, or use pay-per-parcel pricing from $0.10 with no equipment purchase.
