Features

Everything a reseller needs. Nothing they don't.

Built for part-time flippers and full-time operations alike.

AI-tailored crosslisting

Write an item once. FlipFinch rewrites the title and description for each marketplace — keyword-dense for eBay, hashtag-friendly for Depop, buyer-warm for Poshmark.

Auto-delist on sale

The moment an item sells anywhere, every other listing is pulled automatically. No more double-sells, cancellations, or angry buyers.

Real profit analytics

Marketplace fees are calculated per sale with each platform’s actual fee schedule. See net profit — not vanity revenue — by month and marketplace.

A full REST API

Everything in the dashboard is available over the API: inventory, crosslisting, sales, analytics. Build your own tools on top of FlipFinch.

One inventory, everywhere

A single source of truth for every item — cost, price, SKU, photos, status — synced to every marketplace listing it powers.

Your data stays yours

Export everything anytime. API-first design means you’re never locked in.

How it works

Up and running in minutes

Add your inventory

Enter items once with cost, price, photos and condition — or push them in through the API.

Crosslist in one click

Pick marketplaces, and FlipFinch generates platform-tuned listings and publishes them.

Sell and relax

When an item sells, other listings auto-delist and your profit dashboard updates with real fees.

Developer-first

The only reselling platform with a real API

Automate sourcing pipelines, sync with your own spreadsheets, or build a custom storefront. Every plan includes API access with clear rate limits and simple bearer-key auth.
