How it works

Follow one order from click to doorstep.

Meet Sarah, your next customer. Tonight, from her couch, she finds your shop and clicks Buy. Tomorrow morning it’s your turn. Here’s her order, from both sides.

  1. Sarah · Monday, 9:41 PM

    Sarah picks your shop.

    Two beeswax pillar candles, honey and cedar, because she can’t decide. A stoneware mug and a cedar sachet trio too, and she’d like them by the weekend. She’ll never see Postsale. Everything she sees next comes from you.

    A woman on her sofa in the evening, laptop open and card in hand, checking out online.

  2. You · Tuesday, 8:02 AM · at the laptop

    Sarah’s order, with all the others, in one place.

    It’s already there from Shopify, with items and address filled in. Type “Unshipped Shopify orders from this week” and the list narrows. Save it as a filter for tomorrow.

    Every store’s orders. One list.Type what you’re after and the list narrows.Sample data

  3. You · 8:14 AM · at the scale

    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. For #4501: $6.40, Ground Advantage. Easy returns are part of your success, so you include a pay-on-use UPS Ground return label with her shipment.

    Pick the cheapest, the fastest or any rate you like. Sample rates.

    Include a Pay-on-Use Return Label chosen on a shipment, set to come back with UPS, UPS Ground, in the same packaging as the shipment

  4. You · 10:30 AM · at the printer

    Click Create. Your labels and packing slips print together.

    Postsale makes every label in one go, whatever the carrier. Sarah’s return label prints with her shipping label and goes in the box before it ships. Packing slips and invoices carry your logo. Want a personal touch, like a gift note? Design your own.

    Six orders ready to ship: USPS ×3 $20.47, UPS ×2 $58.67, FedEx ×1 $31.40, carrier cost $110.54, Shipsurance $0.75, $111.29 in total, with a Create 6 Labels button

    A 4×6 label, a packing slip with the label built in, an invoice and a gift note. Print on a thermal label printer or the inkjet or laser printer you already have.

  5. Sarah · Tuesday evening · on her phone

    Sarah hears it’s on the way, from you.

    Your shipment email carries your logo and a Track your order button. One tap opens a tracking page with your store’s name and logo, not the carrier’s.

  6. Sarah · Friday, 4:12 PM

    Friday, like she hoped.

    Her phone says delivered, and the box is under her arm. She hasn’t opened it yet. What she finds inside is the part only you can make.

  7. Sarah · the next Monday

    The honey one goes back.

    The cedar candle is the one for her. She packs the honey one into the same box and sticks on the return label that was already inside. No printing, no emailing the shop.

    RETURNhoney

  8. You · Tuesday

    She drops it off. You’re already in the loop.

    Once her return label is on the move, your automation emails you that a return from order #4501 is on its way, so you’re ready for it. UPS charges for a return label only when it’s used, so you pay for this one.

    Edit Automation: Return In Transit. Trigger: a label’s tracking status has changed, to In Transit. Condition: Return label equals true. Action: Send email

    An automation that emails you when a return label is in transit.

She kept the rest. She’ll be back for more.

Connect your store and ship your own orders the same way. It works whether you buy labels on a carrier’s website today or already use another shipping app.

A note from the team

Every box you ship has your name on it.

To a new customer, it’s their first impression of you. So you sweat the parts nobody sees: the tissue, the tape, the note tucked on top, the “where’s my order?” email you answer before breakfast. Your customers feel all of it the moment the box opens.

Persistive, LLC 1 of 3

Everything between Buy and the doorstep is our business. Before Postsale, we spent years building shipping platforms that carried hundreds of millions of shipments and billions in sales. We built Postsale so you can keep that care as you grow, with more of your day left for the tissue and the note.

“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.”
Michael PetersAccount Director

Some days you’d rather just ask.

Connect Claude or ChatGPT to Postsale and ask for the week’s shipping the way you’d ask a colleague. It finds the orders, compares your rates and buys the labels you pick. Then you call it a week.

Sample conversation. You ask: "Which orders still need to ship today? Find the cheapest label for each, unless the customer asked for a carrier." The assistant uses Postsale to search orders and get rates, then answers: 6 orders are waiting, #4501 to #4506. Cheapest rate for each, and the carrier the customer asked for where they did: #4501 Sarah Chen, Springfield, IL: USPS Ground Advantage, $6.40. #4502 Dale Pruitt, Knoxville, TN: USPS Ground Advantage, $5.90. #4503 Rosa Delgado, El Paso, TX: USPS Ground Advantage, $8.17. #4504 Kevin Tran, Seattle, WA: UPS Ground, $28.84. #4505 Beth Ann Riley, Montpelier, VT: UPS Ground, $29.83. #4506 Tom Okafor, Toronto, ON: FedEx International Ground, $31.40.
