How it works
Four steps to set up, then it looks after itself.
Connect your sheet
Point SheetSurfer at the Google Sheet you already keep your stock in. It stays the master record — nothing is moved into a new system.
Map your columns
Tell it which column is the title, the price, the quantity. Import your rows in one pass and fill in anything missing afterwards.
Switch on your marketplaces
eBay, Whatnot, Shopify and Cardmarket each connect with their own settings, so a listing only goes where you want it.
Let it run
Stock, listings and sales keep in step on a schedule. Every run is logged, and anything that fails is reported to you.
What it can do
Everything below is switched on per account, from inside the app.
eBay listings from your sheet
Create and update listings straight from the rows you already maintain, with postage and category rules applied for you.
Sales read back automatically
Sold items are matched to your stock, written to your solds tab and taken off the quantity, so overselling stops.
Daily card prices
Riftbound market, low and trend values refreshed every day, converted to pounds and written back to your sheet.
More than one marketplace
Push the same inventory to Whatnot and Shopify, and pull their sales back into the same solds tab.
Alerts worth reading
Low stock, out of stock, new sales and sync failures, in one email at the time of day you choose.
Your own API
Hand your stock and sales to your own website through a key you control, with the endpoints you choose switched on.
Numbers you can act on
Takings, best sellers and stock value, charted over the period you care about.
One account, one shop
Your sheet, your items and your marketplace credentials are yours alone. No other account can see or touch them.
Card catalogue built in
Browse Riftbound and TCGCSV sets, search by name or number, and fill a card's set, rarity and details straight into the row.
Multi-item listings
Group cards of the same kind into one eBay listing, with each card as its own variation and its own quantity.
Multi-buy promotions
Set quantity discounts on eBay — buy two, save 10% — by category, from one screen, and end them just as easily.
Repricing rules
A daily pass applies your percentage or value-band rules to every price and writes the new figures back to your sheet.
Import an existing sheet
Bring a sheet you already keep in without duplicating a single row, mapping your own columns as you go.
Monitors itself
A read-only health check of the whole system, a meter for how much of each API is being used, and a live view of every running sync.
Getting in
SheetSurfer is not open to anyone who signs up. Access is given in one of two ways, and either one unlocks the whole app for that account.
- A key — issued to you and entered once on the access screen. It unlocks the account it is used on.
- Permission — asked for from the access screen and granted by us to your account.
