About Postsale
We turn every sale into a lasting relationship.
Shipping, tracking, and delivery are where one-time buyers become repeat customers.
Postsale brings it all together.
Why we built Postsale
The post-purchase experience was broken. Merchants were juggling fragmented tools for shipping, tracking, and customer communication, and losing customers in the gaps.
Everything between checkout and delivery was scattered across systems. Automation rules broke. Tracking was inconsistent. Support tickets went unanswered. The moments that mattered most for building customer trust were the ones getting the least attention.
Growing merchants felt it most. The more they shipped, the more their customers felt it: inconsistent tracking, generic emails, unresolved claims. Volume was supposed to be a reward. Instead, it was eroding the relationships they’d worked to build.
We asked a simple question: What if the post-purchase experience was designed with the same care as the storefront? That question became Postsale: a single platform where labels, notifications, and customer touchpoints work together instead of apart. Our mission is to give every merchant the same post-purchase experience that the largest retailers have, without the enterprise budget.
And we made a deliberate choice about how to build it. Postsale isn’t backed by private equity, owned by a marketplace, or subsidized by a carrier. We answer to the merchants who use us. We built Postsale for people who expect more from their shipping platform.

What drives every decision we make
Four beliefs, and what they look like when we build to them.
The sale doesn’t end at checkout.
The label, the tracking email, the delivery: those are where customer trust is built or broken. Most platforms treat them as an afterthought.
Every feature we build starts with one question: does this make the post-purchase experience stronger? If it doesn’t, we don’t ship it.
Automate the obvious.
If a task can be described in a rule, a human should not be doing it.
We measure success by how much of your shipping runs itself. When Postsale is working well, you’re free to focus on your business.
Predictable is fair.
Pay for features, not volume. Your shipping platform shouldn’t penalize you per package.
Every Postsale plan is a fixed monthly price. Pick the tier that fits. The price stays fixed. No per-label software fees, no surprises.
Support is not a cost center.
It’s where trust is built. The quality of support shapes every decision a merchant makes about their platform.
Chat, email, and phone. Every channel gets the same care. However you reach us, the experience should be a great one.
Shipping should fade into the background.
Shipping should be something you stop thinking about.
That’s why Postsale is built automation-first. Rules handle the repetitive work so merchants can focus on designing products, talking to customers, and planning the next launch instead of managing every label by hand.
That efficiency extends to your customer experience. Branded emails and invoices go out under your name. Tracking feels consistent across carriers. Shipment protection is built in, not bolted on. Customers don’t need to know Postsale exists. They just see a brand that delivers.
We took that idea further with AI integration, giving merchants another way to work with their shipping data alongside the tools they already use.

Modern, comprehensive solutions for eCommerce merchants. Postsale is our flagship product.
Our team has managed hundreds of millions of shipments and billions in GMV across the platforms that came before this one. We started Persistive because merchants’ post-sale needs were underserved, fragmented across tools that were never designed to work together. Every decision we make is measured against one question: does this make the merchant’s life meaningfully better? If the answer is anything less than yes, we keep working.
