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." Setup for each assistant: https://www.stacksync.com/mcp.md ![Plastics and molding systems connected through Stacksync two-way sync: Salesforce, NetSuite, Shopify, Dynamics 365 F&O, SQL Server, PostgreSQL](https://www.stacksync.com/images/industry-heroes/icp-plastics-molding-800.webp) Connect direct-store variants and pack quantities to the approved NetSuite product and order model. Stacksync fits plastics manufacturers combining wholesale production with e-commerce and needing a shared view of released, saleable stock. Define channel allocation and quality eligibility before promising that every finished piece can be sold online. The store sells packs, the ERP counts pieces, and recently molded stock may still be on hold or reserved for a wholesale order.

When this fits ## Built for this operating problem Plant operations, customer service and IT teams at US injection molders, extruders and plastics manufacturers with 100–1,000 employees. ### Keep packs and pieces explainable Preserve the buyer’s original selling unit alongside the reviewed ERP conversion. ### Publish eligible stock Use inventory’s agreed channel policy so held trial output and existing commitments do not inflate the offer. ### Handle catalog changes deliberately Retain accepted historical pack definitions while reviewing future variant and packaging changes. The process, end to end ## Follow the work across systems a plastics brand sells colored products directly while supplying distributors from the same facility. Ask to see a pack-based order and a quality hold on one color, including the resulting quantity interpretation and the accepted order reference.

No. Product, quantity, order and fulfillment operations need individual scope and permission checks. ### What should the pilot include? A pack conversion, a held lot, a revised pack definition and a repeated order message. ### What should be measured? Track quantity corrections, manual order reconciliation and accepted order completion, separating inventory-policy problems from transfer failures. ### Where does two-way sync end and a workflow begin for NetSuite and Shopify pack orders? Two-way sync is the starting point: it keeps the Shopify store variant, the NetSuite item and the reviewed pack definition aligned and carries each channel order line into NetSuite through the object-scoped writes you enable. Workflows come next when a quality hold on a color lot must route the affected commitments to inventory review. Genies come later, gathering the evidence behind a disputed pack conversion so product operations can decide. EDI enters only when distributors send releases as documents, outside the store.
