Customer story
Shipping wasn’t their business either. Until it was.
AirBaton is a boutique marketing group with a small team. When a client needed 5,000 prizes mailed before a fixed deadline, they became the shipping department overnight.
“Postsale made the process not only easy, but possible.”
Caleb SheppardFounder, AirBaton“I don’t think we would have met our deadlines without the customer support we’ve received.”
Katie HoffmeisterAccount Director“Postsale has helped me more confidently say yes, without a doubt, we can fulfill any shipment orders.”

How it works
How Postsale’s shipping software works.
A customer clicks Buy tonight. Here’s that order from your list to the printer and on to their doorstep. Less time shipping means more time for the people and things you love.
You · Tuesday, 8:02 AM · at the laptop
Every order from every store in one place.
New orders come in on their own from Shopify and your other stores, with items and address filled in. Type “Unshipped Shopify orders from this week” and the list narrows. Save it as a filter for tomorrow.

Buy the label without the second-guessing.
Rates for that exact box, side by side: discounted USPS rates, built in or on your own USPS account, and your own FedEx and UPS rates. Choose Economical and Postsale picks the lowest. Add a pay-on-use return label to the shipment, and UPS charges for it only if your customer uses it.
Pick the cheapest, the fastest or any rate you like. Sample rates.

Click Create. Your labels and packing slips print together.
Postsale makes every label in one go, whatever the carrier. Return labels print with the shipping labels and go in the box. Packing slips and invoices carry your logo. Want a personal touch, like a gift note? Design your own.

When a return label starts moving, an automation emails you that the return is coming back, so you’re ready for it.

Questions before you start.
How much does Postsale cost a month?
Five plans from $9.99 to $169.99 a month, based on how many shipments you send. Launch is $9.99 a month for up to 200 shipments. There are no per-label software fees and no overage fees. If you ship more than your plan includes, we’ll ask you to move up. Postage is separate.
Do I pay a fee for every label?
No. Your plan is one monthly price. Each label costs only its postage, at your discounted USPS rates or your own FedEx and UPS rates.
Do I need a card to try it?
No. Your 14-day free trial starts without a card and runs on Soar, our top plan, so every feature is on. When it ends, you pick the plan that fits how much you ship and add a card then.
Can I switch from another shipping app?
Yes. Connect Amazon, BigCommerce, eBay, Miva, Shopify, Square and WooCommerce and your orders come in on their own. Connect your own FedEx and UPS accounts to keep your negotiated rates, and print USPS labels with the built-in option or your own account. Orders from anywhere else come in from a CSV file. A real person helps you set up and replies the same business day, Monday to Friday, 8 AM to 5 PM Central.
Does it work with Shopify?
Yes. Connect your Shopify store and orders come in on their own, and tracking goes back to Shopify when you create the label. Postsale also works with Amazon, BigCommerce, eBay, Miva, Square and WooCommerce.
Can I use Postsale without an online store?
Yes. Every account comes with a Manual Orders store, so you can type in an order, like a phone order or a one-off business shipment, and ship it the same way. You can also upload orders from a spreadsheet, or make a label from an address in an email or message with Postsale Anywhere.
Do I need my own USPS account?
No. Print discounted USPS labels right away with Postsale’s built-in USPS option, or connect your own USPS account. FedEx and UPS use your own accounts and negotiated rates.
Can I print on the printer I have?
Yes, on a 4×6 thermal label printer or the inkjet or laser printer you already have.
Will a real person help me?
Yes. Email support@postsale.com or ask for a call from the contact page, and a real person replies the same business day, Monday to Friday, 8 AM to 5 PM Central. We’ve spent years on shipping platforms, across hundreds of millions of shipments and billions in sales.
Can I ship from my own tools or an AI assistant?
Yes. Connect Claude or ChatGPT on every plan, and it searches your orders, compares rates and creates labels when you ask. Postsale Anywhere, the desktop app and Chrome extension, makes labels for orders that arrive in an email, a message or a spreadsheet, on every plan. Developers can connect their own systems with the API and webhooks on the Soar plan.
What is ecommerce shipping software?
It’s the tool between your store and the carriers. Postsale brings your orders in from every store, compares FedEx, UPS and USPS rates, prints labels in batches and keeps your customers posted with tracking.
Volume-tiered platforms raise the price as I grow. Does Postsale?
Your price goes up only when you move to a bigger plan. Each of the five plans is one monthly price for the shipments it includes, from $9.99 a month, with no per-label software fees and no overage fees. If you ship more than your plan includes, we’ll ask you to move up. Postage is separate.
There are free tools. Why pay for Postsale?
Free tools are built to buy a label. Postsale is built to run the shipping side of a growing store: every store’s orders in one list, labels in batches, your own name on the emails and tracking page and real people to help.

Tomorrow, someone clicks Buy.
Be ready for them. Bring your own orders into Postsale and try it free for 14 days.
