Three marketplaces. One inbox.
If you sell on eBay, Poshmark, and Mercari, you are checking three apps all day and still missing messages. One Market Place pulls every buyer message into a single inbox, drafts your listings from a photo, and shows what you actually made after fees.
Photograph it, post it, answer everyone in one place
Built around how reselling actually works — standing in a thrift aisle with a phone in one hand.
Connect your accounts
Sign in to eBay and to Gmail once. Nothing to install, no passwords typed into our app — you approve access on eBay's and Google's own pages.
Photograph the item
Tap the camera button. The AI reads the tag and drafts a title, description, tags, condition, and a suggested price — all of it editable before you post.
Post and reply from one screen
Copy the ready-made listing into each marketplace, then handle every buyer message from a single inbox instead of three apps.
The parts of reselling that eat your day
One combined inbox
Offers, questions, comments, and sales from all three marketplaces in one list, sorted by what needs you first. Nothing sits unanswered for two days because it landed in the app you didn't open.
Listings drafted for you
Photograph an item and get a title, description, tags, and condition written for you. It reports what it can actually see and leaves the rest blank rather than inventing details you'd have to catch.
Priced per marketplace
Each platform takes a different cut. The app sets a price for each one so the same amount lands in your pocket, and shows the fee and your net before you post.
Double-sell guard
When an item sells anywhere, every other listing for it is flagged to pull down — so you don't sell the same jacket twice and eat a cancellation.
Profit that counts everything
What you paid, what it sold for, the platform's fee, and the shipping you covered. Real profit per item and per month, not gross sales.
Made for the phone
Add it to your home screen and it behaves like an installed app — camera included — because sourcing happens standing up, not at a desk.
Taking a small number of sellers
One Market Place is running live for a working reseller today. We're opening it to a handful more before a general release, so we can tune it around real closets and real inboxes.
Pricing agreed at onboarding — no surprise per-listing fees.

Before you ask
How do my listings get onto the marketplaces?
You write nothing twice. Photograph the item once and the app drafts the whole listing — title, description, tags, condition, and a price tuned to each marketplace's fees so the same amount lands in your pocket. Getting it live on each marketplace takes seconds, and posting straight to eBay from the app is on the roadmap.
Can I answer buyers without opening three apps?
That's the whole point — every offer, question, and comment lands in one inbox, sorted by what needs you first. eBay replies send straight from the app. For a Poshmark or Mercari reply, one tap drops you into the right conversation in their app and the thread stays tracked here, so nothing sits unanswered.
How does it see Poshmark and Mercari activity?
Through the notification emails those platforms already send you. You connect Gmail with read-only access, and the app only ever looks at messages from Poshmark and Mercari. It cannot send, delete, or change your mail. If you've turned those notifications off, switch them back on — that's what the app reads.
Does it work on my phone?
Yes. It's a web app built for the phone — add it to your home screen and it behaves like an installed app, including the camera button for photographing an item while you're still standing in the aisle. Nothing to install from an app store.
What does it cost?
One Market Place is in early access with a limited number of seller spots. Each seller gets their own private instance that we host and support, and pricing is agreed at onboarding. Get in touch and we'll walk you through it.
Who's behind it?
Arcturus Consulting. We build, host, and support every app we ship — the same team that runs an AI parts finder on a 40,000+ SKU catalogue. When something breaks, you talk to the people who wrote it.
