Why teams connect Coupa and Scaleway Postgres

Work with Coupa's financial data straight from Scaleway Postgres: read it with ordinary queries, write to it from your own code, and let Stacksync keep both sides consistent.

Engineers need finance data more often than finance systems make it easy to get: for internal tools, reporting services, or logic that reacts to invoices and payments. Working through the vendor API means rate limits, pagination, and glue code that has to be maintained forever.

Stacksync mirrors Expense Reports, Requisitions, Purchase Orders, Invoices from Coupa into Materialized views, Schemas, Sequences, Columns in Scaleway Postgres and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Scaleway Postgres, and rows your code writes or updates flow back into Coupa with validation, so the finance system stays the system of record.

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 Run a two-way sync between Scaleway Postgres and SaaS tools so edits made in either system converge on the same rows
  • 04 Replicate the application database into a warehouse for analytics without writing custom pipelines

Common sync patterns

Write back safely

Updates written to the synced tables in Scaleway Postgres propagate into Coupa, so automations can create or correct finance records without custom integration code.

React to financial events

Changes in Coupa appear in Scaleway Postgres as row changes, so you can trigger downstream logic with the database tooling you already use.

Query finance data like any other data

Customers, invoices, and payments from Coupa live in Scaleway Postgres as regular tables or collections your team can join, index, and query.

What you can sync between Coupa and Scaleway Postgres

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 Scaleway Postgres objects How this pairing syncs
Accounts Chart-of-accounts segments and GL codes; usually mastered in the ERP and written into Coupa so requisitions and invoices code correctly. Materialized views Precomputed result sets that can be read on a schedule for downstream syncs. Accounts is specific to Coupa and Materialized views to Scaleway Postgres — 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. Schemas Namespace tables so multiple applications or environments can be synced selectively. Contracts is specific to Coupa and Schemas to Scaleway Postgres — 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. Sequences Generate primary keys; sync tooling must respect them when writing rows. Expense Reports is specific to Coupa and Sequences to Scaleway Postgres — 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. Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. Requisitions is specific to Coupa and Columns to Scaleway Postgres — each maps to any object or custom field on the other side.
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. Tables Primary sync unit; each table maps to an object or table on the other side of the sync. Purchase Orders is specific to Coupa and Tables to Scaleway Postgres — 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. Views Read-only sources for shaping data before it leaves the database. Invoices is specific to Coupa and Views to Scaleway Postgres — each maps to any object or custom field on the other side.

How changes propagate between Coupa and Scaleway Postgres

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 Scaleway Postgres 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 applied to Scaleway Postgres as a row-level write, with types converted between the two schemas.

Scaleway Postgres Coupa Sub-second propagation

DetectionChanges in Scaleway Postgres are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication where the managed instance permits it.

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.
  • Scaleway Postgres: Throughput is bounded by instance size and connection limits rather than API quotas.
