What we build for sellers
Amazon seller inventory software
Seller inventory stays wrong when the warehouse count, the Amazon count, and the spreadsheet are updated in different places. The stock a person sees has to be the same record the next order will change.
Amazon seller inventory software →Amazon order management for sellers
Order management for a seller is the path from the selling channel to fulfillment. If someone retypes the order, the stock, the report, and the shipment can each describe a different order.
Amazon order management system for sellers →Amazon seller reporting software
A seller report is only useful when it is the same sales, stock, and orders the team already worked. A spreadsheet built after the fact is a second story about the day.
Amazon seller reporting software →Selling Partner API developer for seller operations
An approved SP-API developer builds the seller system that talks to Amazon: inventory, orders, reporting, and the repeated operational steps. ZigCode Labs was approved in October 2026, with global marketplace access for the roles requested. Approval is not an Amazon partnership.
SP-API developer in India →One workspace, one connection, one set of reports.
The seller workspace, the marketplace connection, and the reports are one system. Orders and stock stay in step. Automation runs on that same record. AI is used where it removes a repeated step, and a person can still check the result.
