01Overview

Every channel, every warehouse: one source of truth for e-commerce vendors.

Silver Connection is a multi-tenant supply-chain dashboard for any e-commerce vendor. It brings sales and stock from Shopify, Amazon, Target and bol.com into one place, replaces the spreadsheets teams used to run inventory, production, purchase orders, invoices, shipping and forecasting, and answers the question every founder asks first: where is my money right now?

I co-founded the product as its tech partner and designed and built it end to end: the data model and migrations, multi-tenant permissions, the marketplace integrations, an import pipeline that moves vendors off their spreadsheets, and Carga, an AI assistant that answers questions about a vendor’s own supply chain.

Key Features

“Where Is My Money?”

The home screen splits a vendor’s capital into money buckets (stock on hand, in production, in transit, receivable) with a cross-tenant portfolio view for operators.

Product Spine

Every SKU has one page linking its purchase orders, production drops, invoices, stock and sales, navigable entirely from the keyboard.

Carga AI Assistant

A streaming Claude assistant with fourteen read-only, tenant-scoped tools and a navigation tool that opens the right screen for you.

Marketplace Integrations

Sales and stock from Shopify, Amazon, Target and bol.com land in one dashboard. Scheduled syncs run every thirty minutes, and every run can be previewed before it applies and reversed afterwards.

Spreadsheet Import

Batched Excel/CSV import for products, purchase orders, invoices, sales and stock, with an audit trail and a rollback guard.

Forecasting & Replenishment

PO suggestions from sales velocity, weeks-of-stock traffic lights, multi-currency handling and a command palette for power users.
