CRM ↔ data warehouse
in lockstep, both ways

Sync Salesforce and Snowflake bidirectionally in real time, so analysts query fresh CRM data and ops write enriched warehouse fields back to the record, with no separate reverse-ETL bill.

Where CRM and warehouse drift apart

Three reasons your CRM and warehouse disagree.

Most teams pay for ETL one way and reverse-ETL the other, then spend their week reconciling the two. The seams show fast.

01 - Two vendors

ETL in, reverse-ETL out, two bills to babysit

Salesforce to Snowflake runs on one tool, Snowflake to Salesforce on another. Two schedules, two failure modes, two invoices, and nobody owns the round trip end to end.

RELIABILITY
02 - Schema drift

A new Salesforce field silently breaks the load

Add a custom field in Salesforce and the warehouse load fails or drops it quietly. Analysts query stale columns and trust erodes one missing field at a time.

SCHEMA
03 - Write-back lag

Enriched scores land hours after the rep needs them

Models compute a health or fit score in Snowflake, but reverse-ETL ships it to Salesforce on a schedule. The rep opens the record before the number arrives.

Is this ETL, reverse-ETL, or both?

Both, in one tool. Stacksync syncs Salesforce to Snowflake and back bidirectionally in real time, so you don't pay two vendors or stitch two schedules to close the loop.

What happens when someone adds a Salesforce field?

The mapper detects new and changed fields, so a new custom field surfaces to map instead of silently breaking the load. Schema drift becomes a one-click decision, not an outage.

How are conflicting edits resolved?

Field-level conflict policies decide per field whether the CRM or warehouse wins, with last-write-wins or source-of-truth rules, so a rep edit and a model write never clobber each other.

How fresh is the data on each side?

Sub-second to low-seconds via Salesforce CDC and warehouse change streams. Analysts query current CRM data and reps see freshly computed scores without waiting on a nightly job.
