Why teams connect Coupa and Rootstock ERP

Keep Coupa and Rootstock ERP agreeing on customers, invoices, and balances, whether they split the finance workload or one is replacing the other.

A dedicated finance tool and an ERP end up side by side for practical reasons: a subsidiary runs lighter software than headquarters, billing runs in a specialist system while the enterprise system holds the wider view, or the company is mid-migration and both are live. Whatever the split, the two systems describe overlapping customers and transactions, and that overlap drifts without a live connection.

Stacksync syncs Contracts, Expense Reports, Requisitions, Purchase Orders in Coupa with Bills of Material, Inventory Balances, Receipts and Shipments, Salesforce Accounts and Contacts in Rootstock ERP in real time and in both directions. You decide which system wins on which field, and every change made in one is reflected in the other within seconds instead of at the next batch run.

Common use cases

  • 01 Mirror Purchase Orders and their status into an operational Postgres database for spend reporting and three-way match analytics.
  • 02 Export approved Invoices and their lines from Coupa into an accounting/ERP system to drive the AP pay cycle and GL posting.
  • 03 Sync inventory availability by site to e-commerce storefronts so promised dates reflect real stock.
  • 04 Push confirmed sales orders to a 3PL or WMS and write shipment confirmations back to Rootstock.

Common sync patterns

Migration without a hard cutover

When one system is replacing the other, run both in parallel with records matching until the switch is complete.

One customer and vendor master

Where both systems keep records of the same organizations, corrections made in either propagate to the other.

Subsidiary to headquarters

Where Coupa serves a business unit and Rootstock ERP is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.

What you can sync between Coupa and Rootstock ERP

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Coupa objects Rootstock ERP objects How this pairing syncs
Purchase Orders PO headers and lines; synced two-way with ERPs so orders raised in Coupa flow to the ledger and status updates flow back on the /purchase_orders resource. Purchase Orders Procurement documents synced with supplier portals and AP systems. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Accounts Chart-of-accounts segments and GL codes; usually mastered in the ERP and written into Coupa so requisitions and invoices code correctly. Receipts and Shipments Inbound and outbound transactions synced to logistics and 3PL systems. Accounts is specific to Coupa and Receipts and Shipments to Rootstock ERP — each maps to any object or custom field on the other side.
Contracts Supplier contract records with terms and dates; read out for reporting or created from a CLM system. Salesforce Accounts and Contacts Shared CRM masters in the same org, so customer data needs no separate ERP sync. Contracts is specific to Coupa and Salesforce Accounts and Contacts to Rootstock ERP — each maps to any object or custom field on the other side.
Expense Reports Employee expense reports and their lines; exported to AP or ERP for reimbursement and GL posting. Sales Orders Order headers and lines synced to fulfillment, invoicing, and reporting systems. Expense Reports is specific to Coupa and Sales Orders to Rootstock ERP — each maps to any object or custom field on the other side.
Requisitions Employee purchase requests with lines and approval chains; read out to warehouses, or created via the API from upstream intake tools. Work Orders Manufacturing execution records synced to MES, scheduling, and analytics tools. Requisitions is specific to Coupa and Work Orders to Rootstock ERP — each maps to any object or custom field on the other side.
Invoices Supplier/AP invoices with lines and approval status; polled out to accounting and ERP systems for the pay cycle, or created through the API. Items / Products The manufacturing item master, kept aligned with e-commerce and PLM systems. Invoices is specific to Coupa and Items / Products to Rootstock ERP — each maps to any object or custom field on the other side.

How changes propagate between Coupa and Rootstock ERP

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Coupa Rootstock ERP Interval-based propagation

DetectionStacksync polls Coupa for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at and created-at filters (e.g.

DeliveryEach detected change is written to Rootstock ERP through its API, with automatic retries and rate-limit backoff.

Rootstock ERP Coupa Sub-second propagation

DetectionChanges in Rootstock ERP are captured at the source via change data capture — no polling loop against its API. Salesforce Change Data Capture on Rootstock custom objects where enabled (entity selection limits apply).

DeliveryEach detected change is written to Coupa through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Coupa: Coupa does not publish explicit rate limits or expose X-RateLimit/Retry-After headers; integrations page 50 records at a time and back off on 429/503 responses.
  • Rootstock ERP: Consumes the Salesforce org's daily API request allocation, shared with other integrations.
