Stacksync vs Celigo for CRM/ERP integration

A direct comparison on the four things that matter once you're running CRM/ERP integration in production: latency, recoverability, governance, and what it costs over three years.

Latency: scheduled vs event-driven

Celigo's CRM/ERP flows are scheduled. The minimum supported interval is 5 minutes and typical configurations run at 15. That's batch latency dressed as integration. Stacksync runs on change events from each source's native event surface, Salesforce Platform Events, NetSuite SuiteAnalytics queue, HubSpot webhooks, and propagates in sub-second.

5-minute latency is fine for nightly reporting. It is not fine for an inside-sales motion that triggers off CRM changes, or for a finance close that depends on order data being current.

Error replay: per-record vs per-flow

When a Celigo flow fails, you re-run the flow. The flow re-pulls the source and recomputes. If the source has changed, you may not get back the state you needed to replay. Stacksync persists every event in a queue and lets you replay individual records by their original event ID, the event is the source of truth, not the current state of the source system.

  • Celigo: rerun the flow; depends on source state at rerun time.
  • Stacksync: replay from a stored event offset; deterministic regardless of source state.

Governance and field-level audit

Celigo logs at the record level: "this record was synced". Stacksync logs at the field level: "account_owner on this record changed from X to Y, written from Salesforce at 14:02:11 by user Z, applied to NetSuite at 14:02:11.380". The first answers "did it sync?". The second answers every question your compliance team will ever ask.

When this matters
If your CRM/ERP integration touches anything a SOC 2 auditor reads, revenue recognition, customer-data residency, financial close, field-level audit is the difference between "yes" and a written exception.

FAQ

Frequently asked questions

Is Celigo enough for a small NetSuite + Salesforce setup?
If you're under 100k records per object and don't need sub-second latency, Celigo's prebuilt flows can be enough. The break-even point is around the day you start needing per-field conflict rules, replay, or custom-object support, at which point the cost of working around Celigo's model exceeds the cost of switching.
What's the realistic 3-year cost difference?
For a mid-market CRM/ERP setup we typically model 30–55% less in year-three TCO on Stacksync, driven by fewer paid integrations needed (one engine vs many flows), lower engineering time on maintenance, and not paying per-connection licensing.
