Open-source desktop software for managing e-commerce orders, inventory, product mappings, refunds and agent wallets.
SellQuanta is a Windows desktop application designed for e-commerce sellers who manage stock in their own warehouse and sell through online marketplaces. It brings orders, inventory, marketplace SKU mappings, refunds and agent wallets together in one place, and it runs entirely on your own computer.
Products, warehouse product codes, cost price, opening stock, stock adjustments and low-stock levels.
One place to map every marketplace SKU to the right warehouse product, per company.
Map marketplace SKUs from Amazon, Flipkart and Meesho listings to your own warehouse products.
Read order ID, SKU, quantity and amount from supported shipping-label and invoice PDFs. Results are shown for review before saving.
Record sales from scanned labels or manually, with checks for duplicate order IDs and suspicious quantities.
Saving a sale deducts stock from the mapped warehouse product; refunds return it.
Refund a sale within the refund window, return stock and adjust the agent wallet in one step.
Track what each agent owes for the sales recorded on their marketplace accounts.
Record payments against agent wallets and keep a complete settlement history.
Start a new wallet period from a clear baseline without deleting past records.
Export the day's sales to Excel and archive completed months as permanent snapshots.
Import products and mappings from Excel templates and export warehouse and Product Master backups.
Optionally use a vision model running in Ollama on your own computer for labels the text parser cannot read.
Your records are kept in a local database with automatic daily backups on your PC.
SellQuanta has no cloud account and no SellQuanta server. Products, sales, refunds, wallets, backups and exports are stored in a local data folder on your PC.
All records are saved on your computer, with automatic daily backups and Month Close archives in the same local folder.
Ollama integration is optional and runs locally. SellQuanta talks only to the Ollama service you configure (by default on your own computer) and never downloads models on its own.
The SellQuanta app does not include telemetry, usage-tracking or advertising components. Read the SellQuanta Privacy Policy.
The complete source code, build workflow and release history are public on GitHub. Anyone can review how SellQuanta works, build it themselves and contribute improvements.
Free and open source. Your data stays on your PC.
