Why teams connect Kustomer and Syspro
Close the gap between front office and back office: Kustomer and Syspro share customers and status in real time, in both directions.
Kustomer holds the customer relationship; Syspro runs the operations and records behind the business. The two overlap wherever the same organizations and transactions matter to both, and when that overlap is bridged by re-keying or overnight batch, each side spends the day working from stale data.
Stacksync syncs Tags, Notes, Customers, Conversations in Kustomer with AR invoices, GL journals, Warehouses, Customers in Syspro field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.
Common use cases
- 01 Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
- 02 Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
- 03 Write sales orders from e-commerce platforms or CRMs into SYSPRO without manual re-entry
- 04 Keep inventory balances and item masters aligned between SYSPRO and a WMS or storefront
Common sync patterns
Where Syspro manages people and org data: keep Kustomer aligned
Owners, territories, and org structure informed by Syspro stay current in Kustomer.
Where Syspro handles order-to-cash: closed-won flows through
A deal won in Kustomer creates or updates the customer in Syspro with clean data, so fulfillment and invoicing start without re-entry.
Where Syspro is the finance system of record: money status on the account
Invoice and payment state from Syspro shows on the account in Kustomer, so reps see balances before promising the next order.
What you can sync between Kustomer and Syspro
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.
| Kustomer objects | Syspro objects | How this pairing syncs | |
|---|---|---|---|
| Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. | Customers AR customer master records matched against CRM accounts. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping. | |
| Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. | Inventory items The stock master, kept aligned with WMS and e-commerce catalogs. | Custom Objects (Klasses) is specific to Kustomer and Inventory items to Syspro — each maps to any object or custom field on the other side. | |
| Users Agent records map conversation ownership to people in other systems. | Sales orders Orders written in from storefronts and CRMs, with status read back out. | Users is specific to Kustomer and Sales orders to Syspro — each maps to any object or custom field on the other side. | |
| Teams Team assignments support routing parity and reporting. | Purchase orders Procurement documents synced with supplier portals and receiving. | Teams is specific to Kustomer and Purchase orders to Syspro — each maps to any object or custom field on the other side. | |
| Tags Labels on conversations and customers sync for categorization and analytics. | Jobs (work orders) Manufacturing jobs and WIP tracked for production reporting. | Tags is specific to Kustomer and Jobs (work orders) to Syspro — each maps to any object or custom field on the other side. | |
| Notes Internal annotations carry context alongside synced conversations. | Bills of materials Product structures referenced when syncing manufacturing data. | Notes is specific to Kustomer and Bills of materials to Syspro — each maps to any object or custom field on the other side. |
How changes propagate between Kustomer and Syspro
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.
Kustomer Syspro Sub-second propagation
DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.
DeliveryEach detected change is written to Syspro through its API, with automatic retries and rate-limit backoff.
Syspro Kustomer Interval-based propagation
DetectionStacksync polls Syspro for changes on an incremental schedule, reading only records changed since the previous pass. Polling.
DeliveryEach detected change is written to Kustomer through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Kustomer: Subject to the platform's API rate limits.
- Syspro: Throughput depends on the customer's server sizing; many deployments are on-premise.

FAQ
Kustomer and Syspro integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Kustomer and Syspro: authenticate both systems, choose the objects to sync (such as Kustomer's Customers and Custom Objects (Klasses)), 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 Kustomer and Syspro: Where Syspro manages people and org data: keep Kustomer aligned; Where Syspro handles order-to-cash: closed-won flows through; Where Syspro is the finance system of record: money status on the account. Owners, territories, and org structure informed by Syspro stay current in Kustomer.

Kustomer: REST API. Authentication: API key used as a bearer token, scoped by role. Syspro: E.net Solutions business objects, exposed over REST and WCF interfaces in SYSPRO 8. Authentication: SYSPRO operator credentials exchanged for a session token. Stacksync manages authentication, retries, and rate limits on both sides.
-
Kustomer: Kustomer's data model centers on a customer timeline: conversations, messages, and custom object records all appear chronologically against one customer record rather than as separate tickets. Syspro: External access goes through e.net business objects that apply the same validation and business logic as the SYSPRO client, so API writes cannot bypass ERP rules. Stacksync's field mapping accounts for these differences between Kustomer and Syspro 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 Kustomer and Syspro records are not retained after a sync operation.
