Why teams connect Cin7 and PostgreSQL
Give your engineers Cin7's data in PostgreSQL: 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 Sales orders, Purchase orders, Contacts, Branches / locations from Cin7 into PostgreSQL and keeps both sides consistent in real time. Whatever Cin7 is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in PostgreSQL sync back into Cin7 with its validations respected.
Common use cases
- Feed reporting and BI from a continuously synced Postgres replica instead of scheduled ETL scripts
- Expose SaaS objects (CRM contacts, ERP invoices, support tickets) as Postgres tables that internal tools can query and join
- Keep customer records aligned between Cin7 and the CRM to remove duplicate account entry.
- Write purchase orders created in a planning tool back into Cin7 for receiving.
Controlled write-back
Choose exactly which tables and fields may flow from PostgreSQL back into Cin7, keeping the ERP authoritative.
Read ERP records with a query
Records from Cin7 live in PostgreSQL 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 Cin7 interface, limits, and retries.
What you can sync between Cin7 and PostgreSQL
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.
| Cin7 objects | PostgreSQL objects | |
|---|---|---|
| Products SKU records with options and pricing, synced with storefront and marketplace catalogs. | Tables The primary sync target; rows map one-to-one to records in connected SaaS systems. | |
| Inventory levels Stock on hand by branch or location, published outward for availability. | Views Read-side projections used to expose joined or filtered data to a sync. | |
| Sales orders Orders captured from all channels; the main object for fulfillment and revenue syncs. | Materialized Views Precomputed result sets synced outward on a refresh schedule. | |
| Purchase orders Supplier orders synced with procurement and accounting workflows. | Schemas Namespaces that scope which tables a sync reads and writes. | |
| Contacts Customers and suppliers, matched to CRM records to keep account data consistent. | Columns Field-level mapping targets; types are mapped to the connected system's field types. | |
| Branches / locations Warehouse entities that scope every stock movement and order allocation. | Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution. |

FAQ
Cin7 and PostgreSQL integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Cin7 and PostgreSQL: authenticate both systems, choose the objects to sync (such as Cin7's Products and Inventory levels), 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 Cin7 and PostgreSQL: 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 PostgreSQL back into Cin7, keeping the ERP authoritative.
-
Cin7: REST API; note that Cin7 Omni and Cin7 Core (formerly DEAR Systems) are separate products with separate APIs. Authentication: API key credentials (paired with a username or account ID, depending on the product). PostgreSQL: SQL wire protocol (PostgreSQL frontend/backend protocol). Authentication: Database credentials (connection string or parameters), with optional SSL root certificate upload and optional SSH tunnel (SSH user + host); a least-privilege DB user. Stacksync manages authentication, retries, and rate limits on both sides.
-
PostgreSQL: Logical decoding of the write-ahead log (wal_level=logical) provides row-level change capture without adding triggers to user tables. Cin7: Cin7 is two distinct products under one brand: Cin7 Omni and Cin7 Core (the former DEAR Systems), each with its own API, credentials, and object shapes, so a connector must target the right one. Stacksync's field mapping accounts for these differences between Cin7 and PostgreSQL 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 Cin7 and PostgreSQL records are not retained after a sync operation.
