MailUSA Stamps.com vs PirateShip vs ShipStation: Comparison
Price note: Platform fees come from each company’s pricing page as of October 2026. USPS postage examples come from USPS Notice 123, the price list effective October 4, 2026. Fees and postage change often, so check the live pages before you sign up.
Stamps.com vs PirateShip vs ShipStation: Shipping Platform Comparison
Pirate Ship, Stamps.com and ShipStation all sell discounted shipping labels, but they charge for them in very different ways. Pirate Ship has no subscription and says it adds no markup or label fees to USPS and UPS postage. Stamps.com charges a monthly subscription, starting at $14.99 for its Basic plan in October 2026, and its plans add office-mail tools such as stamp printing and, from the Professional plan up, Certified Mail. ShipStation prices its plans by monthly shipment volume, starting at $14.99 for 50 shipments on its Starter plan. It’s built for online stores that want orders from many sales channels in one place, automation and a wide choice of carriers.
One term needs correcting before the comparison. You may still see shipping software advertise “USPS Commercial Plus pricing.” For domestic packages, that tier no longer exists. Pirate Ship says USPS merged its two commercial tiers, Commercial Base and Commercial Plus, in 2019, and USPS’s current price list shows a single set of commercial prices for Priority Mail, Priority Mail Express and USPS Ground Advantage. This guide uses USPS’s own term, Commercial Pricing.

What “USPS Commercial Pricing” Means in 2026
USPS publishes two sets of domestic package prices in Notice 123. Retail prices are what you pay at a Post Office counter. Commercial prices are lower, and you get them by buying labels online. USPS says its own Click-N-Ship tool gives domestic shippers commercial rates on many services, and label platforms such as these three sell them too. USPS also mentions additional savings on select services for businesses that opt in to its Business Rate Card.
For domestic packages, Notice 123 has one commercial table per service, labeled simply “Commercial.” There is no separate Commercial Plus price for Priority Mail, Priority Mail Express or USPS Ground Advantage. Pirate Ship explains that USPS merged the Commercial Base and Commercial Plus tiers in 2019, and it says some software still uses the old names. You’ll also still see both names on USPS’s international pages. Notice 123 prints “Commercial Base” and “Commercial Plus” tables for Priority Mail International and Priority Mail Express International, but the prices in each pair of tables are the same. Stamps.com’s carrier page still describes its USPS prices as “Commercial Base pricing.”
Pirate Ship also says it gives users USPS Connect eCommerce pricing, a level USPS launched in 2022 that Pirate Ship describes as cheaper than Commercial Pricing. Those prices don’t appear in Notice 123, so the only way to check them is to get a quote. Some services have no online discount at all. A 1 lb Media Mail package, for example, cost $4.39 at both the retail and the commercial single-piece price in October 2026.
Pricing Breakdown
Pirate Ship
Pirate Ship charges no monthly fee, label fee or markup, and it doesn’t ask for a credit card when you sign up. It says it is “paid by the carriers, not by you.” Its rate pages cover USPS Ground Advantage, Priority Mail (including Cubic and Flat Rate), Priority Mail Express, Media Mail and USPS international services. On the UPS side they run from UPS Ground and Ground Saver to Next Day Air and UPS Worldwide Express. Pirate Ship says its UPS discounts are taken off UPS Daily Rates and apply only to shipments from the United States. It doesn’t list FedEx or DHL.
For most people shipping USPS or UPS packages, the only cost of using Pirate Ship is the postage itself. The trade-offs are scope and support: two carriers, help by chat and email, and fewer order-management tools than ShipStation.
Stamps.com
Stamps.com listed three plans in October 2026:
- Basic, $14.99 a month: one user, up to 10 shipping labels and 25 stamps a month, address verification, free pickup scheduling, and chatbot and help-center support.
- Professional, from $29.99 a month: three users, unlimited stamps and labels, Certified Mail and Registered Mail, batch printing, international shipping, tracking emails, reports, live chat and phone support, and QuickBooks Online integration.
- Multi-Location, from $49.99 a month: 10 users per location, two locations included, location permissions and reporting, and a dedicated account team.
Every plan includes UPS, USPS and FedEx access, and Stamps.com also lists DHL Express among its carriers. There’s a 30-day risk-free trial, after which the subscription bills monthly unless you cancel. Postage, insurance and other add-ons are charged separately. Stamps.com advertises free postage and supplies when you sign up, but its pricing page doesn’t state the amount. It also offers desktop and mobile apps.
The Basic plan’s label cap matters for package shippers. If you use all 10 labels, the $14.99 fee works out to about $1.50 per label. That’s more than the commercial discount on many light packages: an 8 oz USPS Ground Advantage package to Zone 5 cost $9.35 at retail and $8.24 at commercial prices, a difference of $1.11.
ShipStation
ShipStation prices each plan by the number of shipments you make per month. These are the monthly-billing prices on its pricing page in October 2026. ShipStation advertises 20% savings if you pay annually.
| Shipments per month | Starter | Standard | Premium |
|---|---|---|---|
| 50 | $14.99 | $29.99 | $349.99 |
| 500 | $39.99 | $89.99 | $449.99 |
| 1,000 | $79.99 | $149.99 | $599.99 |
| 2,000 | $119.99 | $174.99 | $699.99 |
| 5,000 | $174.99 | $249.99 | $799.99 |
Starter tops out at 5,000 shipments a month. Standard and Premium continue up to 100,000 shipments, at $3,599.99 and $7,499.99 a month.
Starter includes three users, unlimited store connections, automated rate shopping, return labels, basic automations, reporting, and email and chat support. It uses ShipStation’s discounted carrier rates. To connect your own negotiated carrier accounts, get a branded tracking page and branded returns portal, or use phone support, you need Standard or higher. Standard also raises the user count to 10 and removes the limits on automation rules. Premium adds inventory and warehouse-management tools and 15 users.
ShipStation says it charges nothing beyond the subscription except for extra users and some add-ons. It doesn’t charge to connect selling channels, apart from what it calls Premium Integrations, or carrier accounts on plans registered on or after July 8, 2025. It offers a 30-day free trial without a credit card, and its “ShipStation Promise” gives a full refund within 90 days if you aren’t satisfied.
If you use the whole allowance, the subscription costs about 30 cents per shipment at the 50-shipment Starter tier ($14.99 divided by 50) and about 8 cents at the 500-shipment tier ($39.99 divided by 500).
Postage Discounts Compared
The table compares USPS retail prices with USPS commercial prices for some common packages, using Notice 123 as of October 2026.
| Service | Retail price | Commercial price | Savings |
|---|---|---|---|
| USPS Ground Advantage, 8 oz, Zone 5 | $9.35 | $8.24 | 12% |
| USPS Ground Advantage, 5 lb, Zone 5 | $18.85 | $14.53 | 23% |
| USPS Ground Advantage, 20 lb, Zone 8 | $72.15 | $42.14 | 42% |
| Priority Mail, 1 lb, Zone 5 | $14.05 | $13.82 | 2% |
| Priority Mail, 5 lb, Zone 5 | $24.20 | $23.27 | 4% |
| Priority Mail Medium Flat Rate Box | $25.80 | $22.02 | 15% |
| Priority Mail Express, 2 lb, Zone 5 | $62.20 | $54.41 | 13% |
Source: USPS Notice 123, effective October 4, 2026. Notice 123 lists Zones 1 through 9. Your zone depends on the distance between the origin and destination ZIP Codes.
There’s no single savings percentage. In these examples, commercial prices were 2% to 42% below retail. Ground Advantage savings grew with weight and distance. Priority Mail’s discount was small in the middle zones, where a 1 lb package to Zone 5 saved 23 cents. It was larger close to home and far away. A 1 lb Priority Mail package to Zone 1 cost $11.50 at retail and $9.44 at commercial prices, and a 5 lb package to Zone 8 cost $39.00 and $30.93.
Because USPS publishes its commercial prices, any platform that passes them through without markup should show the same USPS price for the same package. Pirate Ship says its Connect eCommerce prices go lower still, and Stamps.com and ShipStation describe their USPS rates as discounted. The simplest check is to quote one of your typical packages on each platform before you commit.
For UPS, Pirate Ship says its rates are discounted from UPS Daily Rates. Stamps.com and ShipStation also advertise discounted carrier rates, and both offer FedEx, which Pirate Ship doesn’t.
Which Platform Should You Choose?
Choose Pirate Ship if:
- You ship mostly USPS and UPS packages and don’t want a subscription.
- You sell on Shopify, eBay, Etsy, WooCommerce, BigCommerce, Squarespace or Square, or you can upload orders from a spreadsheet.
- You don’t need FedEx or DHL.
- Live chat and email support are enough for you.
Choose Stamps.com if:
- Your office mails letters and documents as well as packages and needs stamp printing, Certified Mail or Registered Mail (Professional plan and up).
- You want USPS, UPS, FedEx and DHL Express in one account.
- You want phone support or QuickBooks Online integration (Professional plan and up).
- Several people or offices share the account and need user roles or reporting by location.
Choose ShipStation if:
- You sell on several channels, such as Amazon, Walmart, eBay, Etsy, TikTok Shop and your own Shopify store, and want every order in one queue.
- You want automation rules and automated rate shopping across carriers.
- You need a branded tracking page, a branded returns portal or your own negotiated carrier accounts (Standard plan and up).
- You also ship pallets. ShipStation’s plans include LTL freight rate comparison and booking.
Platform Strengths and Limitations
Pirate Ship costs nothing beyond postage, and it says it passes through USPS Commercial Pricing with no markup. Its limits are carrier choice, with USPS and UPS only, and support by chat and email.
Stamps.com is the only one of the three whose pricing page lists stamp printing, Certified Mail and Registered Mail, so it suits offices that send documents as well as parcels. It also covers four carriers. For package shippers, its Basic plan is tight at 10 labels a month, and for USPS and UPS packages its fee pays for features rather than for cheaper postage than a free service offers.
ShipStation has the broadest feature set of the three, with multichannel order import, automation, returns, inventory tools and LTL freight. You pay more as your volume grows, and the Starter plan lacks phone support, branded tracking and the option to use your own carrier accounts.
Key Takeaways
- USPS has one commercial price tier for domestic packages. “Commercial Plus” is an outdated name.
