What Sedonis receives, for this record (illustration)
Default. Encrypted in transit; Sedonis can read this copy.
Inside the app
The maths your spreadsheet was for.
Marketplace fees, side by side
Fee models for eBay, Vinted, Depop, Etsy, Vestiaire Collective and more. Set the take-home you want and see the price to list at on each one.
Listing preparation
One item becomes a paste-ready listing per marketplace, shaped to each title limit. You copy it in yourself: Sedonis never logs into your accounts.
Also inside
- Stock age and cash tied up. See how much money sits in unsold stock and which items have gone 30, 60 or 90 days without selling.
- Sales and a delist checklist. When something sells, a delist checklist shows every other marketplace it is still listed on, so you take it down before it double-sells.
- Net profit. Profit, margin and ROI after the marketplace fee, from the same number everywhere in the app.
Questions
What resellers ask us.
What does it cost?
One app is free, no card needed. Profit and P&L tracking, every app and unlimited invoicing are on Pro, £6.99 a month, with a 14-day free trial.
Does it post or delist for me?
No. Sedonis does not post, edit or delist on any marketplace, and it never logs into your accounts. It prepares the listing for you to paste, and when you record a sale it gives you a checklist of everywhere else to delist. Automatic delisting is not built.
Which marketplaces does it cover?
The fee calculator covers eBay, Vinted, Depop, Etsy, Vestiaire Collective, Grailed, Facebook Marketplace and, in the US, Mercari and Poshmark, with the fee model for each. Fees are modelled for a private or business seller where they differ. Postage is entered separately.
Who can see my sourcing and margin data?
By default (Standard), a copy syncs to our servers over an encrypted connection, and we can read it. Turn on Vault, free on every plan, and it is encrypted on your device before it syncs, so we cannot read it.
Do I pay tax on reselling?
If you are trading to make a profit, usually yes. Sedonis keeps your profit figures ready, but check GOV.UK or an accountant for your situation.
