Built for the seller who reads the fine print.
Every module below is shipped and running — not a roadmap. This is what ArbiKey actually does, screen by screen.
Profit, not revenue
Revenue is a vanity number. The dashboard leads with net profit, average ROI and margin, then breaks the month down by category so you can see which niche is carrying you and which one is a hobby.
- Net profit, ROI, margin and order count
- Category donut and month-over-month trend
- Monthly profit goal with a progress bar you'll actually check
Answer the question before you buy
Source cost in, target margin in, list price out. Every eBay fee, your shipping, VAT and today's ECB exchange rate are applied automatically — so the number it gives you is the number that survives contact with reality.
- Break-even price and target-margin price, side by side
- Live currency conversion — cross-border maths handled
- Saves your calculation history so you can revisit a decision
The month that adds itself up
Log a sale in a few seconds. Supply cost, fees and shipping come along for the ride, so the profit figure is final, not provisional. Returns knock it back down — because pretending they don't is how people convince themselves they're winning.
- Searchable order history, fast at thousands of rows
- Returns and refunds tracked against the original sale
- PDF invoices and CSV export, ready for your accountant
Import, list, sync — without touching a spreadsheet
A Chrome extension pulls the product straight off Amazon or AliExpress. One click lists it to eBay through eBay's own Listing API — title, price, category and images filled in for you. Connect your eBay account and orders, fulfillment status and tracking numbers keep themselves up to date.
- One-click import from Amazon & AliExpress, one-click listing to eBay
- Automatic eBay order & fulfillment sync via secure OAuth connection
- Live supply price & stock monitoring, so a source change never surprises you
Boring where it counts.
You are trusting this thing with your business numbers. Here is what that's built on.
Row-level security
Your data is isolated at the database level, not just in the interface. Another account cannot read your rows even if something upstream goes wrong.
Tamper-proof audit log
Every insert, update and delete is written to an append-only log with the fields that changed. Nobody — including us — can quietly rewrite your history.
Encrypted backups
On Solo and above, your catalogue and sales can be backed up encrypted, and restored if you ever need to roll something back.
See it against your own numbers.
Import a CSV, or add ten products by hand. You'll know within an hour whether this is for you.
