Help Centre
Everything you need to know about using ScanJunki.
Getting Started
How do I create an account?
Click 'Start free trial' on the homepage. Sign up with your email and password, or use Google. You'll get 7 days of full access for free.
Do I need to link my eBay account?
It's recommended but not required. Linking your eBay account gives you better, more accurate pricing data. You can link it during onboarding or later from settings.
How do I select my marketplace?
During onboarding, you'll choose your primary eBay marketplace (e.g. eBay UK). This sets the correct currency and fee schedule. You can switch marketplaces anytime from the header.
Scanning Products
What barcodes are supported?
ScanJunki supports UPC (12 digits), EAN (13 digits), and ISBN barcodes. Type or paste the barcode number into the search bar and hit Scan.
Why does a scan show no results?
Not all products have active eBay listings. Try switching to a different marketplace, or check that the barcode is correct. Some niche products may have very few listings.
What does the pricing data show?
You'll see average listing prices, price ranges, the number of active sellers, and a price distribution chart. If sold data is available, you'll also see historical sold prices.
Profit Calculator
How are eBay fees calculated?
Fees are calculated per-category and per-marketplace. This includes the Final Value Fee, regulatory operating fee, per-order fee, and payment processing fee. You can also add Promoted Listings ad fees in settings.
What about VAT?
If you're VAT registered, enable it in Settings. The calculator will account for output VAT on the sale and reclaimable input VAT on your costs and fees.
Can I change the sale price?
Yes. The sale price auto-fills from the average listing price, but you can edit it to see how different price points affect your profit.
Account & Billing
How much does ScanJunki cost?
£20 per month after your 7-day free trial. No credit card required to start the trial.
How do I cancel?
You can cancel your subscription anytime from your account settings. You'll keep access until the end of your billing period.
Can I change my email or password?
Account management features are coming soon. For now, contact us at sales@robertscotts.com for any account changes.
