Resale inventory, connected
From purchase to profit, nothing gets lost.
Create a Deal, carry each item into Inventory, then record the Sale. FlipKeep keeps the original cost and later changes attached, so your resale records stay useful after the item is gone.

A clearer view of every flip.
Refreshed screens, faster reports, and more dependable settings.
A consistent design throughout
Overview, Inventory, Deals, sales, and Settings share calmer colors, clearer cards, and more consistent layouts.
Faster reports, clearer exports
Reports build faster, and sales CSV values match their column headings, including reporting currency and cashback.
Settings you can rely on
Saved fee presets keep their fixed-fee currency when edited. If a setting cannot be saved, the app tells you and keeps the previous value.
How it works
A straightforward workflow for every flip.
You do the buying and selling. FlipKeep keeps the resale details organized and the profit math honest.
Deal
Record the buy
Add the source, items, currency, cost, discounts, shipping, customs, rewards, and refunds. Advanced details stay out of the way until you need them.
Item
Know what you still own
Each resellable item gets its own cost and status: In Stock, Listed, Sold, Returned, or Removed.
Sale
See what you actually made
Record the payout and seller costs. If it is refunded or returned, FlipKeep keeps that event in the history instead of hiding it.
Profit details
Here is what goes into your profit.
Start with the money from completed sales. Subtract what you paid for the items, the costs of selling them, and any money you returned. Add rewards and credits that count toward the result.
