Because this is built to order, there is a delivery lead time rather than an instant download. After purchase we scope your channel mix and catalog, then typically build, install and configure the app within about 2 to 4 weeks depending on how many marketplaces you connect and how complex your category mapping is. We confirm a concrete timeline during scoping before any build work begins.

We support the app we built. That covers fixing issues, adjusting sync and mapping rules as your catalog changes, and adapting to marketplace or Shopify Admin API changes that affect your integration. The $249 covers the one-time build and handover; ongoing maintenance beyond initial support is arranged separately so you only pay for what you need. We are the team that wrote the code, so support is direct, not a generic helpdesk.

We build connections to major global marketplaces such as Amazon, eBay, Etsy and Walmart, scoped to the channels you actually sell on. Each marketplace has its own API, seller-account requirements and category schema, so we confirm your exact channel list during scoping and configure the connectors accordingly. You provide and own the marketplace seller accounts and API access.

The app is designed to prevent it. Shopify is the source of truth for inventory, and it tracks multi-location stock, listens for inventory webhooks, and decrements every connected channel when a unit sells. You can also set a per-channel safety buffer to hold back stock. No system can fully eliminate races during marketplace API delays, so we add reconciliation passes to catch and correct any drift.

You need an active Shopify plan and active seller accounts on the marketplaces you want to connect, along with their API access where the marketplace requires it. We handle the Shopify OAuth install, webhook setup, and all the mapping and sync configuration. Marketplace fees and seller-account costs remain yours and are billed by those platforms, not by us.
