Why teams connect PostgreSQL and Zuora

Work with Zuora's financial data straight from PostgreSQL: 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 Order and Amendment, Account (Billing Account), Subscription, Rate Plan and Rate Plan Charge from Zuora into Primary and Unique Keys, JSONB Columns, Sequences, Custom Types and Enums in PostgreSQL and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against PostgreSQL, and rows your code writes or updates flow back into Zuora with validation, so the finance system stays the system of record.

Common use cases

  • 01 Stream metered Usage records from a warehouse or metering pipeline into Zuora so consumption-based charges are rated on the correct Rate Plan.
  • 02 Two-way sync of Accounts and Subscriptions with an operational Postgres database so product and finance teams read billing state in SQL while changes flow back into Zuora.
  • 03 Let an application write to its own database and have those rows appear as records in business systems in near real time
  • 04 Consolidate data from several microservice databases into one operational Postgres store

Common sync patterns

React to financial events

Changes in Zuora appear in PostgreSQL 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 Zuora live in PostgreSQL as regular tables or collections your team can join, index, and query.

Internal tools without API plumbing

Build dashboards and back-office tools directly on PostgreSQL; Stacksync handles the API calls, rate limits, and retries against Zuora.

What you can sync between PostgreSQL and Zuora

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.

PostgreSQL objects Zuora objects How this pairing syncs
Schemas Namespaces that scope which tables a sync reads and writes. Invoice Billing documents generated from rate plan charges and order line items; typically read out into an ERP or GL for revenue recognition and reconciliation. Schemas is specific to PostgreSQL and Invoice to Zuora — each maps to any object or custom field on the other side.
Columns Field-level mapping targets; types are mapped to the connected system's field types. Payment Payment and refund transactions applied against invoices; read for cash application, dunning, and reconciliation reporting in the warehouse. Columns is specific to PostgreSQL and Payment to Zuora — each maps to any object or custom field on the other side.
Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution. Usage Metered consumption records; written into Zuora from a metering or warehouse pipeline so consumption-based charges are rated and invoiced. Primary and Unique Keys is specific to PostgreSQL and Usage to Zuora — each maps to any object or custom field on the other side.
JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata. Order and Amendment Records of subscription create and change actions; written to Zuora to drive quote-to-cash and read for subscription change history. JSONB Columns is specific to PostgreSQL and Order and Amendment to Zuora — each maps to any object or custom field on the other side.
Sequences Generate surrogate keys for rows created by inbound syncs. Account (Billing Account) The customer billing entity holding contacts, payment methods, and billing settings; synced two-way as the parent record most other Zuora objects hang off. Sequences is specific to PostgreSQL and Account (Billing Account) to Zuora — each maps to any object or custom field on the other side.
Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields. Subscription Recurring or usage-based subscription tied to an Account; read for revenue state and written when provisioning or changing plans from a CRM or app. Custom Types and Enums is specific to PostgreSQL and Subscription to Zuora — each maps to any object or custom field on the other side.

How changes propagate between PostgreSQL and Zuora

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.

PostgreSQL Zuora Sub-second propagation

DetectionChanges in PostgreSQL are captured at the source via change data capture — no polling loop against its API. Logical replication (wal_level = logical) for change data capture via the "Postgres" connector.

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

Zuora PostgreSQL Sub-second propagation

DetectionZuora notifies Stacksync of record changes through webhook events. Incremental extraction on the indexed UpdatedDate column via ZOQL/AQuA stateful mode (high-water mark), plus Callout Notifications (webhooks) for.

DeliveryEach detected change is applied to PostgreSQL as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • PostgreSQL: No API rate limits; throughput is bounded by connection limits, instance resources, and replication slot throughput.
  • Zuora: Concurrency limits: 40 concurrent requests by default, 80 for Object Queries, 200 for high-volume operations (doubled for Performance Booster); HTTP 429 on breach with exponential backoff; OAuth token endpoint is not bound by the limit.
