WATTLEDGER
Global real-time solar & inverter stock ledger
Every pallet of solar stock on Earth, in one living list.
Distributors, manufacturers and wholesalers publish their real warehouse stock. Installers and EPCs see it all, compare the delivered price, and book the shipment in one session.

The problem
Solar stock is everywhere. Finding it is the hard part.
Installers and EPC companies lose days tracking availability across thousands of regional distributors and manufacturers, with no reliable, real-time view of global stock or shipping cost.
Phone calls and WhatsApp
Finding 450 W mono panels means calling five suppliers and waiting for answers. Days lost before a single pallet moves.
Price lists that are stale on arrival
Stock and prices change daily, but they travel as PDFs and spreadsheets. By the time you read one, it's wrong.
No way to compare what it really costs
The cheapest panel in Shenzhen isn't the cheapest one delivered to Madrid. Without freight in the picture, you're guessing.
How it works
From a warehouse in Rotterdam to a roof in Madrid.
A distributor in Rotterdam, a manufacturer in Shenzhen and a wholesaler in Istanbul are logged in to the same system. Their warehouses show up on one constantly updating map: what's there, at what price, how fast it can move.
Suppliers publish live stock
Each supplier's warehouse syncs from their ERP or a scheduled CSV, per product: model, wattage, quantity and their own price. Updates land within minutes.
Buyers search the whole world at once
Filter by product type, wattage band, brand and destination. Every matching pallet, in Europe, Asia or anywhere else, in one ranked list.
Freight is quoted on the spot
Warehouse and destination go to the carrier, and the shipping cost and transit time appear right in the list. Rankings use the delivered price, not the sticker price.
Pay and book in one session
Checkout runs on Stripe Connect. The stock is reserved the moment the order is placed; the supplier is paid their price minus WattLedger's 0.1%.
Every move is on the ledger
Orders, payments, commissions and stock movements are written to a searchable audit log that exports at any time. No more rebuilding a deal from email threads.

Pricing
0.1%. That's the whole business model.

Your price stays yours
Suppliers set prices and margins in their own system. WattLedger never touches pricing.
Built on a ledger
Trust you can export.
Verified suppliers
Suppliers pass business verification (KYB) through Stripe Connect before buyers can order from them.
Reserved the moment you order
Stock is held atomically for your order, so two buyers can never book the same pallet.
A ledger, not a promise
Every order, payment, fee and stock change is logged with who and when, and exports to CSV at any time.
