Stop Paying Drivers to Sort Packages Every Morning
SortLease installs and runs an automated parcel sorter at your station or a shared site. Routes are ready before drivers arrive. You pay per parcel sorted, from $0.10, with no equipment to buy.
The Morning Sort Is Costing You Delivery Time
Packages often arrive mixed: several drivers' parcels in the same cage, gaylord or container. Before anyone can leave, every driver digs out and sequences their own load.
Delivery partners don't have enough space of their own. Three or four of them share one sorting area and take turns on the same floor every morning. None can justify its own sorter or its own space.
The same pattern: several partners working from one shared site. Drivers arrived around 6:00 AM, sorted their own packages by hand and left around 9:00 AM.
Observed at stations our team visited. Times vary by station; measure your own before deciding.
What Does Sorting Cost You Per Package?
The values below are examples. Replace them with your own numbers. Time your drivers' sort for a week first; the most convincing number is the one you measure.
Your numbers
Estimate only, not a quote. Savings are real only when freed hours are used: earlier departures, more stops, less overtime.
From Mixed Containers to Loaded Vans
Your inbound flow stays the same. The sort moves off your drivers' clock.
Packages arrive mixed
Inbound containers come in as they do today. Nothing changes upstream.
The sorter reads every label
The FlowSort S15 scans each package and assigns it to a route using your route plan.
Routes are built before drivers arrive
Packages leave the sorter grouped by route, ready to load. Carrier-required scans stay with drivers.
Drivers load and go
Time that used to be sorting becomes delivery time. You pay only for parcels sorted.
Sized to Your Volume. Built and Run by Us.
Every system is custom-built for your site. Tell us how many parcels you need sorted and how long your sort window is. We design the layout, install it, run it, maintain it and upgrade it. You don't have to plan anything.
3,600 parcels/hour per line
One sorting line handles up to 3,600 parcels an hour, which is enough for most small delivery partners.
Add lines in parallel
Need more? We add lines side by side. Six lines together reach 21,600 parcels an hour.
Vertical or flat layout
Short on floor space? We stack up to six tiers vertically. Open floor? We lay the lines out flat. Compact spacing lets us deploy densely and save floor space.
How our configurations are named
Every system is matched to your site, and the name tells you what was built: V = vertical (tiers stacked, up to six), F = flat (lines side by side), and the number is how many tiers or lines. Each tier or line sorts up to 3,600 parcels an hour.
| Configuration | Layout | Rated parcels/hour |
|---|---|---|
| FlowSort S15-V1 | Vertical, 1 tier | 3,600 |
| FlowSort S15-V3 | Vertical, 3 tiers | 10,800 |
| FlowSort S15-V6 | Vertical, 6 tiers | 21,600 |
| FlowSort S15-F5 | Flat, 5 lines | 18,000 |
| FlowSort S15-F7 | Flat, 7 lines | 25,200 |
Examples only. We design the configuration your volume, sort window and space call for.

Is Automated Sorting Right for Your Station?
Likely a fit
- Packages arrive mixed and drivers sort their own loads before leaving
- First departures are delayed by the sort, or you pay overtime at the end of routes
- Several delivery partners share one crowded site
- You control a facility, or can use a sorting site near your station
Probably not a fit
- Your carrier already stages route-sorted, sequenced totes or carts
- You work entirely inside a carrier building and can't change its package flow
- Sorting takes each driver only a few minutes a day
The Questions Delivery Partners Ask First
Most station owners we talk to worry less about the machine and more about their carrier, their space and their data.
"Will my carrier allow it?"
That depends on your carrier agreement and who controls the facility. Check it first. If the carrier controls the station, we can prepare a one-page pilot proposal for station management.
"Will anyone know I asked?"
No. Your application is confidential. We don't contact your carrier, your station or other partners without your permission.
"We don't have the space."
The sorter is vertical and built for tight sites. When space is short, 3–4 partners can share one sorter in a shared sorting hub. No site at all? We can secure one.
"What about carrier systems?"
The sorter reads printed labels. It doesn't connect to, log into or change any carrier system.
Pay Per Parcel, Share a Hub, or Own the Equipment
Pay-per-parcel
- SortLease installs and operates the sorter
- No equipment purchase
- Monthly invoice for parcels sorted
Shared sorting hub
- 3–4 delivery partners share one sorter
- Separate time windows or lanes
- Each partner pays for its own volume
Rent, lease-to-own or buy
- For larger or multi-site operations
- Rental, lease-to-own or purchase
- Compare total cost before you choose
Final per-parcel rates depend on volume and site. Not sure which model fits? Read rent vs buy or manual vs automated sorting.
Prove It at Your Station in 30 Days
A pilot is measured, written down and removable. If the numbers don't work, the sorter comes out.
1 · Measure first
- Time your current sort for one week
- Record departures and packages per driver
2 · Agree in writing
- Price, custody and insurance set before install
- Carrier agreement checked first
3 · Compare and decide
- Before-and-after sorting hours and departures
- Continue, change or remove after 30 days
See the FlowSort S15 Sort Parcels
Each line sorts up to 3,600 parcels an hour; six lines together reach 21,600 for larger sites. Actual throughput depends on parcel mix, labels and staffing.
Pilot Applications Open Across Major US Metros
We accept pilot applications nationwide and prioritize dense metros where several delivery partners share space.

Frequently Asked Questions
What is pay-per-parcel sorting?
SortLease installs, operates and maintains an automated parcel sorter at your station or a shared site, and you pay for each package sorted, starting from $0.10, instead of buying equipment or paying drivers to sort by hand. How billing works.
Do I need my carrier's permission to use a sorter?
It depends on your carrier agreement and who controls the facility. Check your agreement first. If the carrier controls the station, SortLease can prepare a 30-day pilot proposal for station management. We don't contact your carrier or station without your permission.
Does the sorter connect to carrier systems?
No. The sorter reads package labels and groups packages by route using your route plan. It does not connect to or change carrier systems, and carrier-required scans stay with drivers.
Can several delivery partners share one sorter?
Yes. In a shared sorting hub, 3–4 delivery partners use one sorter in separate time windows or lanes, and each pays per parcel for its own volume.
When does automated sorting not make sense?
When your carrier already delivers route-sorted, sequenced containers, or when sorting takes each driver only a few minutes. Use the driver sorting cost calculator: if manual sorting costs less per package than the per-parcel price, automation will not save money.
What happens in a 30-day pilot?
You time your current sort for a week, SortLease installs and runs the sorter for 30 days under written terms, and both sides compare driver sorting hours and departure times before and during the pilot. The sorter is removable if the pilot does not continue. Apply here.
Is SortLease affiliated with Amazon, FedEx, UPS or USPS?
No. SortLease is an independent US company based in Sheridan, Wyoming, and is not affiliated with or endorsed by any carrier. Carrier names are used only to describe the kinds of operations we serve.
How many parcels per hour can it sort?
Each sorting line handles up to 3,600 parcels per hour, which is enough for most small delivery partners. For more volume we add lines in parallel; six lines together reach 21,600 parcels per hour. Example: 20,000 parcels in a 2-hour window needs about 10,000 an hour, or three lines. Size your setup.
What do names like S15-V3 or S15-F5 mean?
They describe the configuration we built for a site. V means vertical (tiers stacked, up to six); F means flat (lines side by side); the number is how many tiers or lines. Each tier or line sorts up to 3,600 parcels an hour, so S15-V3 is about 10,800 an hour and S15-F5 about 18,000.
Do I need to design or plan the installation myself?
No. Every system is custom-designed for your site: vertical (up to six tiers) or flat, depending on your space. SortLease designs, installs, operates, maintains and upgrades it. You tell us your volume, sort window and space; we handle the rest.
Can I rent or buy a sorter instead?
Yes. Larger or multi-site operations can choose equipment rental, lease-to-own or purchase. See financing options.
