Proof you shipped it right.
Proof of what came back.

ShowFlow captures timestamped, tamper-evident photo proof at packing and at return — so when a buyer claims "item not received" or sends back the wrong thing, you have real evidence, not just your word.

You already know the feeling.

A buyer says they never got it. Tracking says delivered. Now it's your word against theirs — and on most platforms, that's a fight you start already behind.

Or a return comes back, and it's not what you shipped. Different item. Damaged on purpose. Buyer keeps the real one, sends back a substitute, and you're left holding a chargeback with no way to prove what actually happened.

Sellers on Poshmark, Depop, Mercari, eBay, and Whatnot already know this problem — and right now, most of them are protecting themselves with a phone camera and a prayer, filming their own returns just to have something if it goes wrong.

ShowFlow makes that instinct official, automatic, and actually usable as evidence.

Two moments matter. We capture both.

Every order gets the same evidence trail, no matter where you sold it.

📦
Packing proof

When you pack it

Before you seal the box, ShowFlow prompts a quick photo — the item, the box, the label — hashed the instant it’s captured, so it can’t be edited or backdated afterward.

Return proof

If it comes back

Record photos of any return the moment you open it. Side by side with the original packing proof, you have a complete before-and-after record tied to that exact order.

Works with the platform you actually sell on.

ShowFlow isn't built around one marketplace. Add orders manually from Poshmark, Depop, Mercari, eBay, or anywhere else you sell — or, if you sell live on Whatnot, turn on automatic order detection and let ShowFlow catch every win in real time without lifting a finger.

Real tamper-evidence, not just a claim.

Every photo is SHA-256 hashed at the moment of capture — the same idea used to verify a file hasn't been altered. Evidence is kept for at least 75 days, well past USPS's 60-day claim window.

🧾

Works with any platform

Add orders manually from Poshmark, Depop, Mercari, eBay, or anywhere else you sell — the packing and evidence flow works the same regardless of where the sale happened.

🏷️

Whatnot auto-detection, if you use it

Sell live on Whatnot too? Turn on automatic order detection and ShowFlow catches every win in real time, auto-prints a claim tag, and starts the evidence flow — no manual entry.

🔐

SHA-256 hash on every file

Every photo is cryptographically hashed the moment it’s captured — verifiable proof it hasn’t been edited or replaced since that moment, not just your word.
