FAQ
Common questions.
Quick answers across pricing, technical setup, legal, and the boring details that matter.
General
What is Delta?+
Delta is an end-to-end Amazon-to-eBay reseller automation platform. It imports products from Amazon, publishes them to your eBay store with the right policies, tracks Amazon prices in real time, repricing your eBay listings, and syncs orders + dispatches tracking automatically.
Who is Delta for?+
eBay resellers running dropshipping or arbitrage models from Amazon. From beginners running 50 listings up to power sellers running thousands.
Do you support marketplaces other than eBay?+
Today: eBay UK. On the roadmap: eBay US, eBay DE. We focus on UK because that's where we have deep expertise; multi-region rolls out once each market is fully tested.
Can I source from anywhere other than Amazon?+
Currently Amazon only. More sources are on the roadmap - let us know via the contact form which one you'd find most useful.
Pricing & billing
Is there a free tier?+
Yes. The Starter tier is permanently free for catalogs up to 50 active listings. No card required.
How do trials work?+
Paid tiers come with a 14-day free trial. No card needed up front. We email a reminder 3 days before the trial ends.
Can I switch tiers?+
Yes, anytime. Upgrades are immediate. Downgrades take effect at the end of the current billing period.
Do you charge per listing, per order, or per API call?+
No. Your subscription is the only thing you pay us. Listings, price updates, order syncs - everything is included in your plan.
How it works
How fresh are the source prices?+
Depends on your tier. Starter checks daily, Growth hourly, Professional sub-hourly. You can also run a check on a single product on demand, any time.
What happens if a source price can't be read?+
The price freezes rather than dropping to zero - your listing stays safe. You're notified so you can review the product.
How does duplicate detection work?+
When you add or publish a product, Delta checks it against what you already list. Duplicates are blocked before they hit eBay - which keeps your account in good standing.
Can I bring my own data?+
Yes. Add products one at a time, paste a list, or drop a CSV. Delta drafts each listing with title, images, description, and price ready to review.
Is there an API?+
Enterprise customers get API access. Other tiers use the in-app UI only for now.
Compliance & legal
Is Amazon-to-eBay dropshipping allowed?+
eBay's policy allows dropshipping where you are the seller of record and fulfil from a wholesaler. Reselling Amazon products typically falls outside that. We provide the tooling; you're responsible for staying compliant with eBay's seller policies in your region.
What is VeRO and how does Delta handle it?+
VeRO (Verified Rights Owner) is eBay's IP protection programme. Listings of protected brands risk takedowns and account suspensions. Delta flags restricted brands at import and blocks publish until you've cleared the warning.
Where is my data stored?+
Primary database is in the UK. Some service providers may store ancillary data outside the EU; the full list is on our sub-processors page.
Can I delete my data?+
Yes. Account deletion removes all your data within 30 days. Backup retention is documented in the privacy policy.
Are you GDPR compliant?+
Yes. We sign DPAs on request and maintain a public sub-processors list. Email privacy@deltapp.com to request a DPA.
