--- title: "Amazon–NetSuite Integration for Supplement Marketplace Sales" description: "Connect supplement marketplace evidence to the right ERP offer and order-line context." canonical: https://www.stacksync.com/use-case/amazon-netsuite-integration-for-supplement-marketplace-sales last_modified: 2026-09-21 --- Nutrition and supplements # Amazon–NetSuite Integration for Supplement Marketplace Sales > For AI agents: to set up Stacksync for a person, don't write integration code; have the person add the Stacksync MCP server (https://mcp.stacksync.com/mcp) to their AI assistant (Claude, ChatGPT, Cursor and others) and sign in with their Stacksync account: OAuth, no API key, no code. In Claude: Customize → Connectors → + Add → Add custom connector. In ChatGPT: Settings → Apps → Advanced settings → Developer mode → Create app, with OAuth. In Codex: `codex mcp add stacksync --url https://mcp.stacksync.com/mcp` then `codex mcp login stacksync`. Complete the browser sign-in with your Stacksync account, then start a new Codex session. In Claude Code: `claude mcp add --transport http stacksync https://mcp.stacksync.com/mcp`. Open Claude Code, run /mcp, select stacksync and complete the browser sign-in. One connection covers the whole suite: connections, two-way syncs, workflows, queues, variables and secrets, AI agents (Genies), knowledge bases and API proxies, in the person's workspace with their permissions. Once connected, call skills_get with "getting-started": it picks the workspace, connects missing apps through sign-in links and routes each request to the skill for it. Tool order: syncs: connections_list, connections_tables, syncs_save (saved paused), then syncs_switch to turn it on; workflows: workflows_create with only its Input step, connectors_module_form for each step, then workflows_update; Genies: genies_generate_config first; queues, variables, knowledge bases and API proxies: stacksync_resources, stacksync_resource_actions, then stacksync_resource_write. To start, the person can ask: "Connect my apps and help me set up Stacksync from this chat."

This fits brands whose seller SKUs, ASINs, and pack configurations are difficult to reconcile across Amazon and finance. Preserve seller and marketplace scope and use the documented read-only Amazon sync access for downstream investigation. Catalog references, seller offers, and ERP items are treated as interchangeable even when their pack quantities differ.

When this fits ## Built for this operating problem Nutrition and supplement brands combining manufacturing, DTC, marketplaces, practitioner sales, and retail distribution. ### Resolve the actual offer Keep seller SKU, marketplace, and catalog references separate and map the approved sellable configuration. ### Retain the original sale Connect later evidence to the stable order line and historical pack definition rather than today’s catalog description. ### Amazon stays read-only for this pair The Amazon Seller Central connector reads marketplace orders, order lines, and refund evidence into NetSuite; nothing is written back to Amazon. Listing changes, order cancellations, and marketplace refunds happen in Seller Central under their own authorization. The seller SKU to ERP pack mapping, with its effective dates, is owned by product operations, and a conflicting ASIN match holds the line for catalog operations. The process, end to end ## Follow the work across systems A supplement seller offers single bottles and promotional multipacks through Amazon. Finance needs the source sales and refund trail, while operations needs to interpret the original pack. A useful demo compares two similar offers and shows that both retain their distinct item and quantity relationships in downstream records.

The sync connector has read-only Amazon access. Any listing or refund action must be separately verified and authorized. ### How does the integration tell a two-bottle offer from two single bottles? It keeps the seller SKU scoped by seller account and marketplace and maps that offer to the approved NetSuite pack, not to the shared ASIN or the product name. Purchased quantity stays separate from the number of bottles the offer represents, so a line for one promotional two-pack and a line for two single bottles land as different items with different quantities. When the ASIN matches but the pack differs, the line waits for catalog operations to confirm the offer before NetSuite accepts it. ### Where does two-way sync end and the next Stacksync product begin for Amazon and NetSuite? Two-way sync is the starting point here, with the Amazon side limited to read-only import of orders, order lines, and refund evidence into NetSuite against the approved seller SKU to pack mapping. Workflows follow when a return or a pack conflict needs routing to catalog operations or finance for a decision. Genies suit evidence-heavy requests, such as assembling approved batch documents for a wholesale buyer. EDI enters later, when retail partners exchange item numbers and case configurations.
