How it works

A day with FlipSync

FlipSync works inside your own Chrome, signed in as you. No passwords to hand over, and posting never goes through anyone else's servers.

  1. At the car boot

    Snap it on your phone

    Open flipsync.co.uk/phone, take up to 12 photos and add the title, brand, size, condition, price and what you paid. Tick where it should go. It waits in FlipSync on your computer, or tick "Post it as soon as my computer gets it" and it goes up by itself.

  2. At home

    Post it everywhere

    Tick the marketplaces, or all of them, and press Post. FlipSync fills in every sell form in front of you, dropdowns and all: photos, category, brand, size, condition, colour, measurements and parcel size. Then it publishes, while you get on with something else.

  3. On the sofa

    Sold on Vinted. The rest come down.

    FlipSync spots the sale, takes the listing down from eBay, Depop and everywhere else it's live, four sites at a time, and checks they're really gone. You never sell the same item twice.

    • Vinted: sold
    • eBay: removed for you ✓
    • Depop: removed for you ✓
  4. A minute later

    Profit logged

    The sale lands in your stats with your take-home after each platform's fees, set against what you paid for it.

  5. End of the tax year

    Tax year sorted

    Sales, costs and mileage for the year, the £1,000 trading allowance, a tracker for HMRC platform reporting on each site, and a CSV for your accountant.

Fills every form properly

It knows joggers are sweatpants

Every marketplace words things differently. FlipSync has studied each sell form, every category and every dropdown, so your listing lands in the right place on each site.

  • Category matching checked on 4,670 test listings, with sensible fallbacks
  • Pick-lists of each site's own categories, sizes, colours and brands
  • Sizes converted: Medium to M, UK to EU shoe sizes, size ranges and kids' ages
  • Shorthand understood: BNWT, VGC, worn once
  • Knows what each site won't take, so nothing goes where it gets removed
  • Tells you anything it couldn't fill, and never publishes an incomplete listing

Ready for the tax return

Know where you stand with HMRC

Marketplaces now report sellers to HMRC. FlipSync shows how close you are on each one, and keeps the numbers you'd need anyway.

  • Sales, fees, item costs, postage and expenses for each tax year (6 April to 5 April)
  • The £1,000 trading allowance, and whether claiming it beats your actual costs
  • Platform reporting tracker: 30 sales or about £1,700 a year on one site
  • Mileage at 45p a mile, and a CSV of the whole year for your accountant

Your accounts and your data stay yours

No passwords

FlipSync uses the marketplace sessions already signed in in your Chrome. It never asks for, sees or stores a marketplace password.

Data stays on your computer

Your items, photos, sales and expenses are stored in your browser. Our servers only know your email and whether your subscription is active. The exceptions are your choice: items you save on your phone, held until your computer collects them, and a copy of your inventory for your phone to show, if you switch that on.

Works like you do

Listings are posted from your own browser at a human pace, one form at a time, just as if you'd filled them in yourself.

Marketplaces

26 marketplaces, one listing

8 marketplaces with every feature, and 18 more that already cross-list for you, moving up to full support with future updates.

FAQ

Questions

Anything else? Email [email protected].

What does early access mean?

FlipSync is new. Everything on this page works today, and we ship improvements every week, often from what subscribers tell us. Marketplaces change their sites now and then, so you may hit the odd rough edge: report it from FlipSync (Settings › Help › Report a problem) and we fix it fast. Subscribe during early access and you keep your price.

How do the plans work?

FlipSync is free to download. On Free you pay £2 per item with credits, and they never expire. Or subscribe with your email and a card: Lite (£10 a month: 25 items for sale at a time on up to 3 marketplaces) or Full (£25 a month: unlimited, all 26 marketplaces). Subscriptions are charged straight away and then every month until you cancel. You can switch plans from your account page. Cancel any time from your account page and you keep access until the end of the month you've paid for.

How do credits work?

A credit costs £2 and posts one item to as many marketplaces as you like.

  • You pay once per item. Posting it again, relisting, editing or taking it down is free.
  • Buy as many as you need from your account page. They never expire.
  • On Lite, a credit covers an item that goes over your plan: more than 25 items for sale, or more than 3 marketplaces.
  • Posting a lot? Lite or Full can work out cheaper, and you can switch any time.
Which browsers does it work in?

Google Chrome on Windows, Mac and Chromebook, and other Chromium browsers like Edge and Brave. It doesn't run on phones, because mobile browsers don't support extensions, but you can add items on your phone at flipsync.co.uk/phone and post them from your computer.

Is there a phone app?

Yes. Open flipsync.co.uk/phone on your iPhone or Android phone, sign in with your FlipSync email and add it to your home screen. Take the photos and fill in the details there, and the item waits in FlipSync on your computer, ready to post everywhere. It can show your inventory and sales too, once you switch on Show my inventory on my phone in FlipSync's Settings. It's included in Lite and Full.

How do I install it?

FlipSync is on the Chrome Web Store: press Add to Chrome, then sign in to your FlipSync account when it opens. It updates itself.

Will it get my marketplace accounts banned?

FlipSync fills in the same forms you would, in your own browser, one at a time on each site. It doesn't use hidden APIs or log in from servers. As with any tool, follow each marketplace's rules and don't post duplicate listings on the same site.

Does it work with my existing listings?

Yes. Find listings scans your shop on eBay, Vinted, Depop, Facebook Marketplace, Preloved, Wadded, Reluv or Bidzzy and imports everything you tick, with photos, prices, SKUs and item specifics. If the same item is on several of them, FlipSync spots it by its photos and keeps it as one item. Import sales brings in your past sales from eBay, Vinted and Depop too.

What does "beta" mean for the other marketplaces?

eBay, Vinted, Depop, Facebook Marketplace, Preloved, Wadded, Reluv and Bidzzy have full feature support: posting, Sync, import, offers and taking it down when it sells elsewhere. The other 18 are in beta: Etsy, Gumtree, Shpock, Vestiaire Collective, Grailed, HEWI London, Poshmark, Mercari, Kidizen, Reverb, Discogs, Kleinanzeigen, Marktplaats, leboncoin, Wallapop, Tise, OfferUp and Craigslist. They already cross-list your items, filling in most of each form for you, and they are moving to full support with future updates.

Where is my data stored?

On your computer, in Chrome's storage for the extension. Back it up to a file from Settings at any time. Your items only reach us in two ways, both your choice. An item you save on your phone waits with us until your computer collects it, then it's deleted. And if you switch on Show my inventory on my phone, we keep a copy of your listings and recent sales (titles, prices, SKUs, storage spots, where they're listed and a small picture; never costs, descriptions or buyer details) so your phone can show them. Switching it off deletes that copy. We never see your marketplace passwords.

Is the tax page tax advice?

No. It's a record-keeping aid that applies the published HMRC thresholds to your own figures. If you're not sure whether you're trading, check GOV.UK or ask an accountant.

How do I cancel?

Sign in to your account page and press Manage subscription. Cancelling stops future payments, and you keep access until the end of the period you've paid for.
