Why teams connect Postgres Heroku and Sage 300
Give your engineers Sage 300's data in Postgres Heroku: 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 AR Customers, AP Vendors, GL Accounts, Journal Batches from Sage 300 into Postgres Heroku and keeps both sides consistent in real time. Whatever Sage 300 is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in Postgres Heroku sync back into Sage 300 with its validations respected.
Common use cases
- Keep several Heroku app databases aligned with one system of record
- Reflect billing and subscription records into the app database so product logic reads local rows
- Write web and EDI orders into Order Entry and return order status to the source channel.
- Replicate GL, AR, and AP detail to a warehouse for consolidated multi-company reporting.
Controlled write-back
Choose exactly which tables and fields may flow from Postgres Heroku back into Sage 300, keeping the ERP authoritative.
Read ERP records with a query
Records from Sage 300 live in Postgres Heroku 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 Sage 300 interface, limits, and retries.
What you can sync between Postgres Heroku and Sage 300
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.
| Postgres Heroku objects | Sage 300 objects | |
|---|---|---|
| Sequences Generate surrogate keys for rows created by inbound syncs. | AR Invoices and Receipts Billing and payment records replicated for cash and revenue reporting. | |
| Follower Databases Heroku-managed read replicas usable as low-impact sync sources. | AR Customers Receivables customer master synced to CRMs and billing tools. | |
| Tables Standard Postgres tables; the primary two-way sync target for app data. | AP Vendors Payables vendor master synced with procurement and payment systems. | |
| Views Read-side projections exposed to outbound syncs. | GL Accounts Chart of accounts read for transaction mapping across integrations. | |
| Materialized Views Precomputed result sets synced outward on refresh. | Journal Batches GL entries staged in batches that must be posted; a common write target for external systems. | |
| Schemas Namespaces that scope which tables a sync reads and writes. | Order Entry Orders Sales orders written from e-commerce or EDI feeds. |

How the Postgres Heroku and Sage 300 connectors work
Postgres Heroku
- Integration surface
- SQL wire protocol (standard PostgreSQL)
- Authentication
- Database credentials from the Heroku DATABASE_URL config var; SSL required
- Change detection
- Trigger-based capture or polling in most configurations; log-based logical replication availability depends on plan and Heroku's managed server settings
- Capabilities
- read · write
- Rate limits
- No API rate limits; connection counts and performance are bounded by the Heroku Postgres plan
Sage 300
- Integration surface
- Sage 300 Web API (REST) on newer releases; .NET/COM SDK and direct SQL Server access on-prem
- Authentication
- Sage 300 user credentials (Basic auth on the Web API); database credentials for direct SQL reads
- Change detection
- Scheduled polling; batch-oriented modules with no webhook surface
- Capabilities
- read · write

FAQ
Postgres Heroku and Sage 300 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Postgres Heroku and Sage 300: authenticate both systems, choose the objects to sync (such as Postgres Heroku's Sequences and Follower Databases), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Change detection on Postgres Heroku: Trigger-based capture or polling in most configurations; log-based logical replication availability depends on plan and Heroku's managed server settings. On Sage 300: Scheduled polling; batch-oriented modules with no webhook surface. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Postgres Heroku side: Primary and Unique Keys, JSONB Columns, Sequences, Follower Databases, plus custom fields where Postgres Heroku exposes them. On the Sage 300 side: AR Customers, AP Vendors, GL Accounts, Journal Batches. Stacksync auto-detects both schemas and converts types between the two systems.
-
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 Postgres Heroku and Sage 300: Controlled write-back; Read ERP records with a query; Internal tools and automations without API code. Choose exactly which tables and fields may flow from Postgres Heroku back into Sage 300, keeping the ERP authoritative.
-
Postgres Heroku: SQL wire protocol (standard PostgreSQL). Authentication: Database credentials from the Heroku DATABASE_URL config var; SSL required. Sage 300: Sage 300 Web API (REST) on newer releases; .NET/COM SDK and direct SQL Server access on-prem. Authentication: Sage 300 user credentials (Basic auth on the Web API); database credentials for direct SQL reads. Stacksync manages authentication, retries, and rate limits on both sides.
