About this appAI proposal
Lotline pulls price lists from European suppliers into one normalized catalogue, matches each item to its Amazon listing, and shows margin after fees, shipping and VAT. Instead of opening dozens of spreadsheets, you open one ranked list of deals worth buying.
Built for professional Amazon sellers and online arbitrage sellers in Europe who spend many hours a week sourcing. Set your margin, ROI and category rules once, and Lotline flags new matches as supplier lists change.
The supplier side is the point. Pack sizes, currencies and codes are cleaned up, so two suppliers' offers for the same product can be compared line by line.

- Why this name
- A lot is a batch of stock; a line is a price-list row and a path. Lotline is the line from lot to listing.

How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- No loop in the product. Lotline is a private working tool. Buy sheets go to suppliers, but they carry no invitation to the product, so growth comes from content, communities and direct outreach.
- Do they become customers?
- Suppliers who receive a purchase order are not Amazon sellers. Test whether sellers in forums and groups convert from a free tier with one supplier list.
- First customers
- Solo and small-team online arbitrage sellers on Amazon in Germany, France, Italy and Spain who already buy from several EU wholesalers and spend 20+ hours a week sourcing.
- Where to reach them
- Seller communities: Offer free list-cleaning for sellers in Facebook, Discord and forum groups, then show ranked deals.
- Sourcing content: Publish guides on comparing EU wholesaler lists, with a downloadable margin sheet that leads to the app.
- Direct outreach: Message active sellers with a ranked deal list built from their own supplier file.
- First milestone
- Ten paying sellers on the Seller plan within 90 days, each importing at least three supplier lists.
Why people already pay for this

RisksAI inference
- DataSuppliers send messy, inconsistent lists. Matching quality by EAN decides whether sellers trust the deals, and wrong matches cost real money.
- PlatformDepends on Amazon API access and its terms. Access limits or rule changes could cut fee and price data.
- CommercialSellers may be reluctant to share supplier relationships or lists. Supplier lists may carry licensing limits on reuse.
- CommercialExisting sourcing and research tools may serve the same sellers. The material names none, so overlap is unverified.
- TechnicalCurrency, VAT and fee rules differ by EU country and change over time, so margin figures need steady upkeep.
