Why teams connect Acumatica and Render Postgres
Give your engineers Acumatica's data in Render Postgres: read it with normal queries, write back through the sync, and skip the ERP API entirely.
ERP data sits behind interfaces built for the ERP's own modules, not for your internal systems. Teams that need those records, for reporting services, internal tools, or automations, end up writing integration code against a strict API and maintaining it through every upgrade.
Stacksync mirrors Customers, Vendors, Sales Orders, Invoices from Acumatica into Render Postgres and keeps both sides consistent in real time. Whatever Acumatica is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in Render Postgres sync back into Acumatica with its validations respected.
Common use cases
- 01 Replicate between a Render database and another Postgres or warehouse for migration or environment separation.
- 02 Two-way sync CRM or ERP objects into Render Postgres tables so product and ops teams query business data with plain SQL.
- 03 Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.
- 04 Mirror stock items and quantities to external channels so availability stays accurate across systems.
Common sync patterns
Read ERP records with a query
Records from Acumatica live in Render Postgres as ordinary tables or collections, joinable with the rest of your data.
Internal tools and automations without API code
Scripts and services read and write the synced tables; Stacksync handles the Acumatica interface, limits, and retries.
React to ERP changes
Updates in Acumatica arrive as row changes in Render Postgres, so jobs and triggers can respond as the business record changes.
What you can sync between Acumatica and Render 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.
| Acumatica objects | Render Postgres objects | How this pairing syncs | |
|---|---|---|---|
| Sales Orders Order documents created from e-commerce and CRM systems, read back for fulfillment status. | Schemas Namespaces that organize tables per app or environment; sync targets are scoped per schema to keep synced data isolated and tidy. | Sales Orders is specific to Acumatica and Schemas to Render Postgres — each maps to any object or custom field on the other side. | |
| Invoices AR and AP billing documents synced for payment tracking and CRM visibility. | Columns and Types Full Postgres type system including JSONB and arrays; field mappings preserve native types instead of flattening to strings. | Invoices is specific to Acumatica and Columns and Types to Render Postgres — each maps to any object or custom field on the other side. | |
| Purchase Orders Procurement documents exchanged with supplier-facing systems. | Indexes and Constraints Primary keys, unique constraints, and foreign keys; unique keys drive idempotent upserts and conflict resolution during sync. | Purchase Orders is specific to Acumatica and Indexes and Constraints to Render Postgres — each maps to any object or custom field on the other side. | |
| Stock Items Inventory master data with quantities shared with external sales channels. | Tables Relational tables with full column typing; synced two-way with CRMs, ERPs, and SaaS apps so application data is queryable as plain Postgres rows. | Stock Items is specific to Acumatica and Tables to Render Postgres — each maps to any object or custom field on the other side. | |
| Shipments Fulfillment documents read to update tracking in storefronts and CRMs. | Views Saved queries exposed as read-only relations; read out to BI tools or downstream syncs without duplicating transformation logic. | Shipments is specific to Acumatica and Views to Render Postgres — each maps to any object or custom field on the other side. | |
| Payments Customer payment records reconciled against invoices from payment platforms. | Materialized Views Precomputed query results refreshed on demand; read for fast reporting tables that downstream systems can consume. | Payments is specific to Acumatica and Materialized Views to Render Postgres — each maps to any object or custom field on the other side. |
How changes propagate between Acumatica and Render 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.
Acumatica Render Postgres Sub-second propagation
DetectionAcumatica notifies Stacksync of record changes through webhook events. Push notifications configurable on data changes, plus polling on LastModifiedDateTime fields.
DeliveryEach detected change is applied to Render Postgres as a row-level write, with types converted between the two schemas.
Render Postgres Acumatica Sub-second propagation
DetectionChanges in Render Postgres are captured at the source via change data capture — no polling loop against its API. Logical replication via WAL and replication slots for change data capture when enabled on the instance, with timestamp or cursor-based polling as the.
DeliveryEach detected change is written to Acumatica through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Render Postgres: No API rate limits — throughput is bounded by the instance's plan (CPU, RAM, connection limit); connection pooling is recommended since managed plans cap concurrent connections.

FAQ
Acumatica and Render Postgres integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Acumatica and Render Postgres: authenticate both systems, choose the objects to sync (such as Acumatica's Sales Orders and Invoices), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Acumatica and Render Postgres: Read ERP records with a query; Internal tools and automations without API code; React to ERP changes. Records from Acumatica live in Render Postgres as ordinary tables or collections, joinable with the rest of your data.
-
Acumatica: Contract-based REST API (JSON over versioned endpoints), plus SOAP web services and OData access to Generic Inquiries. Authentication: OAuth 2.0 or cookie-based session login with Acumatica credentials. Render Postgres: PostgreSQL wire protocol (managed Postgres on Render). Authentication: Standard Postgres connection string — host, port, database, user, password with TLS; Render provides internal and external connection URLs and IP allowlisting. Stacksync manages authentication, retries, and rate limits on both sides.
-
Render Postgres: External connections use a separate hostname from Render-internal ones and require TLS; access can be restricted by IP allowlist. Acumatica: The contract-based REST API uses versioned endpoints with a defined entity contract, so integrations pin an endpoint version and remain stable across upgrades. Stacksync's field mapping accounts for these differences between Acumatica and Render Postgres without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Acumatica and Render Postgres records are not retained after a sync operation.
