ShipStation is subscription software built for shipping operations, with plans starting at $14.99/month and volume tiers running out to 100,000 shipments a month (per shipstation.com/pricing, checked 2026-07-28). At three or four parcels a week that fee is the largest line in your shipping cost, which is the whole reason this page exists.
Postage is roughly the same wherever you buy it. What differs between a subscription and a one-off purchase is the fixed monthly cost sitting on top, so that is what we measured.
Read off shipstation.com/pricing on 2026-07-28, with nothing added. ShipStation prices by volume tier inside each plan, so the headline figure is the entry point rather than a flat rate.
Those are the prices of a real operations tool. Batch printing, automation rules, inventory and multiple users are worth money to a business moving hundreds of orders, and none of that is in dispute here.
This table does one piece of arithmetic and shows its working: the published $14.99 entry fee divided by the number of labels you print in a month. Postage sits on top of every figure in the right-hand column.
| Labels in the month | Calculation | Fee spread across each label |
|---|---|---|
| 4 labels | $14.99 ÷ 4 | $3.75 of plan cost per label |
| 12 labels | $14.99 ÷ 12 | $1.25 of plan cost per label |
| 30 labels | $14.99 ÷ 30 | $0.50 of plan cost per label |
| 50 labels | $14.99 ÷ 50 | $0.30 of plan cost per label |
The shape of that column is the argument. A seller posting one parcel every couple of days is paying somewhere near four dollars a label before postage, and a seller clearing fifty is paying thirty cents. Neither of those people is wrong, they are just at different points on the same curve.
A poly-mailer shipment is the archetypal low-volume parcel: light, thin, and shipped by somebody who sold one thing. Here is what our calculator returned for exactly that, with the whole checkout amount shown rather than postage alone.
| Carrier | Service | Price | Transit window returned |
|---|---|---|---|
| USPS | Ground Advantage | $8.86 | 8-9 business days |
| FedEx | Ground Economy | $10.06 | 6-7 business days |
| UPS | Ground | $10.31 | 2-3 business days |
| UPS | 3 Day Select | $15.13 | 5-6 business days |
| UPS | 2nd Day Air | $15.38 | 2-3 business days |
Worth pausing on the third row. UPS Ground quoted 2-3 business days at $10.31 against 8-9 days for the $8.86 USPS row, so a dollar and change bought roughly six days back on this lane. That trade shows up constantly on light parcels and it is invisible if you only sort by price.
Somewhere around thirty or forty parcels a month, the fee per label drops far enough that the automation starts paying for itself in saved minutes rather than saved dollars. Below that line the tooling is mostly idle and the fee is not.
Order sync, batch printing, automation rules, inventory counts and warehouse features. We have none of those. SMKlog quotes a described parcel, sells a US domestic label and hands you tracking, and that is the full extent of it.
A 30-day trial with no card is a genuinely fair offer and worth taking if you might grow into the tool. Just diary the end date. The awkward version of this story is always a plan that renewed quietly through a slow month.
Starter is published as starting at $14.99/month, checked at shipstation.com/pricing on 2026-07-28. Inside that plan the price climbs with monthly volume, reaching $174.99/month at 5,000 shipments.
Take the fee and divide it by your real monthly label count. At 12 labels the $14.99 entry price works out to $1.25 sitting on every label; at 50 it is $0.30. Once that number looks small next to your postage, the software is no longer the expensive part.
Yes. Describe the parcel, pick a live rate, pay and print as a guest. For a 0.7 lb poly mailer running Newark to Atlanta on 2026-07-28 the cheapest rate came back at $8.86 with USPS Ground Advantage, all in.
No, and we would rather say so plainly than imply otherwise. There is no rules engine, no order import and no batch queue here. A shipper who needs those is genuinely better served by ShipStation or a comparable platform.
