Why teams connect Coupa and Pigment

Keep the customer, invoice, and payment records that Coupa and Pigment share consistent in real time, whether the two systems split your finance stack or one is replacing the other.

Two finance systems in one company usually means one of two setups. Either the systems divide the work, with one issuing invoices or serving a business unit while the other holds the books, or one is on its way out and both must stay accurate during the transition. In both cases, the customer, invoice, and payment records the two systems share start to drift the moment updates are keyed twice or moved by hand.

Stacksync syncs Contracts, Expense Reports, Requisitions, Purchase Orders in Coupa with Tables, Scenarios, Data imports, Users and permissions in Pigment bi-directionally and in real time. A record created or corrected in either system appears in the other within seconds, with field-level mapping and conflict resolution in place of CSV exports and nightly batch jobs.

That matters most at close. When both systems agree on who was billed, what was paid, and what is outstanding, reconciliation stops being a hunt for which copy of the truth is current.

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 Keep dimension lists such as departments and cost centers consistent with master data in the ERP.
  • 04 Sync headcount and compensation data from an HRIS into workforce planning models.

Common sync patterns

Where Coupa issues invoices and Pigment holds the books

Invoices and payments recorded on the billing side land in the system of record automatically, so revenue is captured once and correctly.

Parallel run during a migration

When one system is replacing the other, keep both live and matching through the cutover, so no transaction falls between the last export and go-live.

One customer master

A customer's name, billing details, or payment terms corrected in either system update the other immediately, so the next invoice always uses current information.

What you can sync between Coupa and Pigment

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 Pigment objects How this pairing syncs
Contracts Supplier contract records with terms and dates; read out for reporting or created from a CLM system. Applications Planning models organized by domain such as finance, sales, or workforce Contracts is specific to Coupa and Applications to Pigment — 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. Metrics Multidimensional values holding plans and actuals; the main target for inbound data Expense Reports is specific to Coupa and Metrics to Pigment — 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. Dimension lists Master data like accounts, products, or employees that metrics are sliced by Requisitions is specific to Coupa and Dimension lists to Pigment — 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 Row-based transactional data loaded into models from source systems Purchase Orders is specific to Coupa and Tables to Pigment — 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. Scenarios Versions such as budget, forecast, and actuals that give exported figures their context Invoices is specific to Coupa and Scenarios to Pigment — each maps to any object or custom field on the other side.
Suppliers Supplier master records; kept aligned with an ERP vendor master and onboarding tools, synced two-way on the /suppliers resource. Data imports Scheduled loads that bring actuals from ERPs, CRMs, and HRIS into the model Suppliers is specific to Coupa and Data imports to Pigment — each maps to any object or custom field on the other side.

How changes propagate between Coupa and Pigment

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.
