--- title: "NetSuite Postgres sync for automotive shipment lot evidence" description: "NetSuite shipment lines and Postgres lot records joined by the allocated quantities, with missing links held for review rather than inferred by date." canonical: https://www.stacksync.com/blog/automotive-netsuite-postgres-lot-shipment-traceability last_modified: 2026-09-18 --- # Automotive components: connect NetSuite shipments to Postgres lot evidence > 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." Setup for each assistant: https://www.stacksync.com/mcp.md Shipment evidence that answers which recorded lots supplied one NetSuite shipment line, reconciled by quantity and open about gaps in the Postgres record. Author Ruben Burdin · Founder & CEO Published September 18, 2026 Read time 4 min read DATA ENGINEERING ## The operating decision A NetSuite–Postgres shipment-evidence model for automotive components should link accepted order lines, shipped quantities and the recorded lots or revisions supplying them. Keep shipment identity separate from customer acknowledgment or acceptance. Two-way sync can make approved records available across teams, while quality and shipping retain authority over their evidence. The model should help answer which recorded material fulfilled which commitment without inventing traceability where source identifiers are missing. Explore the complete [automotive components integration and automation hub](https://www.stacksync.com/industry/manufacturing/automotive-components) for the systems and processes around this guide. ![Summary card: NetSuite Postgres sync for automotive shipment lot evidence](https://www.stacksync.com/images/blog-highlights/icp-automotive-netsuite-postgres-lot-shipment-traceability.webp) ## What this looks like in automotive components A component supplier ships one customer release from two production lots and later receives a question about a specific revision. The ERP contains the shipment, while a Postgres application holds detailed production and quality references. A join using only item number returns every lot produced that week, which looks comprehensive but does not identify the lots actually shipped. The integration needs the real allocation or shipment relationship, with quantities that reconcile to the customer line. Missing links should become review tasks rather than inferred matches. ## Records, ownership, and update rules | Record | Owner | Operating rule | | --- | --- | --- | | Shipment line | Shipping | Retain the ERP shipment reference, order-line relationship and dispatched quantity. | | Lot or revision evidence | Quality and production | Preserve the recorded material identity and applicable engineering context. | | Fulfillment relationship | Shipping operations | Identify the actual lot quantities contributing to the shipment rather than matching by item and date alone. | | Customer delivery context | Customer operations | Keep receiving plant and release references separate from supplier shipment and quality records. | ![Record ownership diagram: Shipment line, Lot or revision evidence, Fulfillment relationship](https://www.stacksync.com/images/blog-diagrams/icp-automotive-netsuite-postgres-lot-shipment-traceability.webp) *Define the record owner and the rule before enabling updates.* ## Work through the process 1. 01 Define the traceability question narrowly Choose a question the source data can answer, such as which recorded lots supplied one shipment line. Identify the authoritative relationship and its owner. Avoid promising end-to-end genealogy when the available records cover only part of the chain. 2. 02 Model quantities on the relationships Store the quantity assigned from each lot to each shipment line with explicit units. Support split lots and partial shipments. Reconcile relationship totals to the accepted shipment so a many-to-many join cannot inflate shipped quantity. 3. 03 Preserve external and local identities Keep NetSuite transaction references distinct from generated Postgres keys and production-record identifiers. Review historical duplicates before backfill. A common customer part description is useful for display but should not become the linking key. 4. 04 Handle corrections as traceable changes If shipping or quality corrects a recorded lot relationship, retain the prior value and accepted reason according to the process. Recompute the current evidence view without hiding that a correction occurred after dispatch. 5. 05 Test missing and split relationships Use a shipment containing two lots and another with an incomplete source link. The first should reconcile exactly; the second should remain visibly unresolved. Any return update into ERP must follow the verified operation and owner approval. ![5-step operating sequence: NetSuite Postgres sync for automotive shipment lot evidence](https://www.stacksync.com/images/blog-diagrams-mermaid/icp-automotive-netsuite-postgres-lot-shipment-traceability.webp) *Follow the operating sequence; unresolved exceptions return to a responsible reviewer.* ## Handle the exceptions explicitly ### A shipment has no recorded lot link Route the gap to shipping or quality. Do not infer the lot from the nearest production date. ### One lot supplies several customer releases Track the allocated quantities separately so the full lot is not counted on every release. ### The customer reports a different receiving reference Preserve the discrepancy and reconcile the commercial identifiers before merging shipment evidence. ## What to verify before expanding - Lot quantities reconcile to the selected shipment line in the same unit. - Missing relationships remain explicit rather than being filled by approximate joins. - A corrected relationship retains the accepted correction context. - Supplier dispatch is not displayed as proof of customer acceptance. ## Connect this process to the rest of your operation [Explore Stacksync two-way sync](https://www.stacksync.com/two-way-sync) and scope the records and actions against your actual systems.

No. It can expose and connect the evidence actually recorded. Coverage depends on the source relationships, identity quality and operating process. Can a database update change a posted shipment? Only through a separately supported and approved application operation. The evidence model should not overwrite financial or shipping history merely to make a report reconcile. What should the pilot measure? Track time to assemble a shipment evidence packet, unresolved relationship gaps and corrections required after review. Keep data coverage separate from synchronization freshness.
