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."

Author Alexis Favre · Co-Founder & CTO Published September 18, 2026 Read time 5 min read APP TIPS ## The operating decision Steel and fence-material EDI should preserve item specification, buyer purchase line, quantity unit and packaging context from order through receipt and invoice. Bundles, pieces, length and weight are not interchangeable quantities. Use the supplier's implementation guide and approved item conversions, then keep the original supplier values available for review. Procurement owns accepted commercial changes; receiving confirms physical quantity and condition; EDI processing should not silently substitute materials or recalculate the fabrication requirement. Explore the complete [fencing fabrication and installation integration and automation hub](https://www.stacksync.com/industry/construction/fencing-fabrication-installation) for the systems and processes around this guide. ![Summary card: Steel and fence supplier EDI for bundles, pieces and lengths](https://www.stacksync.com/images/blog-highlights/icp-steel-and-fence-material-supplier-edi-map-bundles-pieces-and-lengths-to-project-purchase-orders.webp) ## What this looks like in fencing fabrication and installation A fabricator buys posts and steel sections for several installation jobs. The order uses pieces, the supplier ships bundles and the invoice describes weight for one product group. A partial bundle arrives at the warehouse, with some material allocated to a specific project. The flow needs enough detail to reconcile what was ordered and what can actually be used. A simple quantity field could multiply stock or make a valid invoice appear incorrect. ## Records, ownership, and update rules | Record | Owner | Operating rule | | --- | --- | --- | | Purchase line | Procurement | Retain specification, buyer item, supplier item and ordered quantity unit. | | Approved conversion | Item or production administration | Define the product-specific relationship between pieces, length and other units. | | Package and receipt | Supplier and receiving | Preserve bundle detail and actual accepted quantity. | | Project allocation | Inventory owner | Connect usable material to the approved job requirement. | ![Record ownership diagram: Purchase line, Approved conversion, Package and receipt](https://www.stacksync.com/images/blog-diagrams/icp-steel-and-fence-material-supplier-edi-map-bundles-pieces-and-lengths-to-project-purchase-orders.webp) *Define the record owner and the rule before enabling updates.* ## Work through the process 1. 01 Agree the item and unit mapping Validate supplier item codes against the exact material specification. List the units used for ordering, shipping, stocking and invoicing. Do not assume a standard bundle size or weight relationship applies to every section or supplier product. 2. 02 Retain purchase-line references Carry the buyer PO number and line identifier through supplier acknowledgments, shipment notices and invoices. Keep internal project allocation attached to the relevant line. One order can serve several jobs, so the document header alone should not determine the final allocation. 3. 03 Interpret packaging without inventing quantity Use the actual package content supplied by the partner and confirmed at receiving. A partial bundle must not be expanded to a full standard bundle. Where detail is missing, create a receiving exception and preserve the source document rather than forcing the quantity into a default conversion. 4. 04 Route specification and commercial changes Compare supplier responses with the original order for material, finish, length and price differences. Qualified reviewers decide technical suitability, and procurement accepts commercial changes. Keep these approvals distinct from successful EDI syntax or transport processing. 5. 05 Reconcile receipt and invoice basis Normalize quantities using approved product rules for the comparison finance needs. Keep original units and source references so discrepancies can be explained. Record processing and destination identifiers to recognize retransmissions before they create another receipt or invoice action. 6. 06 Reconcile returns with their original receipts When material is returned, preserve the original purchase line and receipt reference and record the actual returned quantity in the correct unit. A supplier credit is a financial event, while removing usable stock is an inventory event; both need their own confirmed state. Linking them gives procurement and finance a shared explanation of the difference without assuming that every credit means the material physically left the warehouse. ![6-step operating sequence: Steel and fence supplier EDI for bundles, pieces and lengths](https://www.stacksync.com/images/blog-diagrams-mermaid/icp-steel-and-fence-material-supplier-edi-map-bundles-pieces-and-lengths-to-project-purchase-orders.webp) *Follow the operating sequence; unresolved exceptions return to a responsible reviewer.* ## Handle the exceptions explicitly ### Supplier ships a partial bundle Use actual confirmed content and keep missing detail in an owned exception. ### Invoice quantity is expressed by weight Apply only the approved conversion for that product and show the comparison basis. ### Material finish differs from the PO Hold the affected line for specification and purchasing review. ## What to verify before expanding - Bundle counts reconcile to actual accepted pieces or quantities. - Conversions identify the exact product and rule. - Project allocations remain attached to purchase lines. - Retransmitted documents cannot duplicate the business action. ## Connect this process to the rest of your operation [Explore Stacksync EDI](https://www.stacksync.com/edi) and scope the records and actions against your actual systems.

No. Electronic documents describe the supplier's transaction. Receiving confirms what arrived and its condition, especially when packages are partial or damaged. Can the same conversion be used for all steel products? No. A conversion must match the actual material and unit relationship. Similar product names do not establish the same dimensions, weight or package content. What should a supplier pilot include? Test a partial bundle, a mixed-project order, a unit change and a specification mismatch. These cases demonstrate whether the mapping can support real fabrication purchasing rather than only clean sample documents.
