Pricing and billing
What 2,000 light orders a month should cost at a 3PL
At 2,000 orders a month of light, two-unit orders in a poly mailer, the warehouse side of a 3PL bill should run about $2 to $4 per order. Postage adds $7 to $11 more, so the carrier rate is the number to negotiate.
At 2,000 orders a month of light, two-unit orders in a poly mailer, the warehouse side of a 3PL bill should land between $1.82 and $3.95 per order. Postage adds $7.33 to $11.22 per order at USPS Ground Advantage commercial rates. All-in, that is about $9 to $15 per order, or $18,000 to $30,000 a month. Postage is three quarters of it, so the label rate is the number to negotiate hardest.
The question, and why the SFN number looked wrong
A seller on the Shopify Community was launching a stationery store with 10 to 20 SKUs, 2,000 orders a month, most of them several packs of one SKU at 0.5 to 1 lb. The Shopify Fulfillment Network calculator showed $20 or more for a ten-item order. The seller asked what was reasonable, and nobody in the thread gave a number.
Two things have changed since. Shopify sold the Shopify Fulfillment Network to Flexport in May 2023, as Red Stag recounts. And from January 1, 2026, Flexport bills a $5,000 monthly minimum on every account. At 2,000 orders that is $2.50 an order, and most accounts at this volume clear it on fulfillment spend alone.
The $20 figure is explainable too. A ten-item order is one first pick plus nine additional picks, and per-unit pricing stacks up fast. The first thing to check on any quote for light, multi-unit orders is what the second, third and tenth unit cost.
The five lines on a light-item bill
Take a quote apart into pick and pack, additional units, packaging, storage and receiving, and postage. The hidden fees article covers the rest.
Pick and pack
The Fulfillment Advisor's 2025 survey of more than 600 warehouses, summarized by Fulfill.com (updated October 29, 2026), puts the first-item pick and pack at $3.20 per order on average and each additional item at $0.48. Smaller operators' rate cards run $0.99 to $2.00 for the first item, and Racklify (January 17, 2026) sees $1.25 to $2.50 from shelf to box. At 2,000 orders a month the lower end is a fair ask.
Additional units
This line decides a multi-pack business. The survey range is $0.30 to $0.75 per extra item. On a three-pack order that is $0.60 to $1.50 on top of the first pick. Ask whether a shrink-wrapped three-pack counts as one unit or three. If your top SKUs always ship as the same bundle, pre-kit them into one SKU at receiving and three picks become one.
Packaging
Light items go in a poly mailer, and a poly mailer is cheap. A 10 x 13 in tear-proof mailer from Uline is $194 per case of 1,000, or $0.19 each. Some rate cards add $0.75 to $1.50 to pack a mailer on top of the pick, which is many times the cost of the bag. Ask whether packing is inside the pick fee.
Storage and receiving
Twenty light SKUs fit in bins, with no pallet positions needed. The survey average is $3.08 per bin per month, so 40 bins is about $123. Receiving averages $10.52 per pallet, and four inbound pallets is $42. Across 2,000 orders that is about $0.08 per order, a rounding error. A warehouse that bills 20 small SKUs by the pallet is pricing you wrong.
Postage
Under the USPS commercial card in effect from October 4, 2026 to January 17, 2027, Ground Advantage prices every ounce tier under 1 lb the same within a zone, per D'Arrigo Consulting. A 12 oz parcel runs $7.33 to $8.95 across zones 1 to 8, and a 1 lb parcel $8.01 to $11.22, with zone 5 at $9.29. The counter price for that zone 5 pound is $11.70. So a half-pound order and a 15 oz order ship for the same money, and the label is three quarters or more of the all-in cost. The 3PL's carrier rates matter more than its pick fee.
What 2,000 orders a month should cost, line by line
The low end uses Racklify's $1.25 first pick and the survey's $0.30 additional item. The high end uses the survey averages. Two units per order, 40 bins and four pallets a month are our assumptions.
| Line | Rate used | Per order | Per month at 2,000 |
|---|---|---|---|
| Pick and pack, first unit | $1.25 to $3.20 | $1.25 to $3.20 | $2,500 to $6,400 |
| Second unit pick | $0.30 to $0.48 | $0.30 to $0.48 | $600 to $960 |
| Poly mailer, 10 x 13 in | $0.19 each | $0.19 | $380 |
| Storage, 40 bins at $3.08 | $123 a month | $0.06 | $123 |
| Receiving, 4 pallets at $10.52 | $42 a month | $0.02 | $42 |
| Warehouse subtotal | $1.82 to $3.95 | $3,645 to $7,905 | |
| Postage, Ground Advantage commercial, under 1 lb | $7.33 to $11.22 by zone | $7.33 to $11.22 | $14,660 to $22,440 |
| All-in | $9.15 to $15.17 | $18,300 to $30,340 |
As a check, Eightx (July 6, 2026) modeled a 2,000-order month at 1.3 units per order with a $517 minimum and $7.00 postage and landed at $4.40 per order before shipping and $11.40 with it. Our light-item case is lower on the warehouse side because the mailer is cheap and the bins are few.
So a reasonable quote for this seller is $2 to $4 on the warehouse side. Anything over $5 before postage, on half-pound orders in a mailer, deserves a line-by-line explanation. A 3PL that quotes a pick fee without showing its postage rates has shown you the small number and hidden the big one.
How to cut the postage line
- Get commercial rates. On the zone 5 pound above that is $9.29 against $11.70 at the counter.
- Rate shop every label. Regional carriers often beat USPS on light parcels in the lanes they cover. Our regional carriers guide covers who runs where.
- Keep multi-packs under 15.999 oz. Under 1 lb, the ounces do not change the commercial price within a zone, so the second and third pack ship free.
- Stay in a mailer. A box triggers dimensional weight on carriers that apply it, and a mailer almost never does.
What we can do from Remsen Avenue
At BoxHero, pricing is one base rate per order plus a smaller rate per additional unit, quoted on your actual order mix, so a three-pack business gets a three-pack price. Receiving is free, there is no monthly minimum and no term, and the first 10 returns a month are included with $2 per unit after that. Storage is a flat monthly charge tied to the floor space you use, and 20 light SKUs use very little of it.
On the line that matters most, postage passes through at the carrier's rate with no markup, and every label is rate shopped across 12+ carriers. The example on that page is a 2 lb parcel from Brooklyn to Chicago, where UniUni priced at $4.90 against USPS at $5.85, $3.60 under UPS on the same label. Orders in by 3:30pm ET ship the same day from 905 Remsen Ave. If you are still deciding whether to outsource at all, read the five numbers that decide it and how many orders a month a 3PL needs. Send us your SKU list and a month of orders and we will price it line by line.
