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. LATENCY PLATFORM ## Six products. One Platform. Replace many legacy vendors.

The four concerns every data and RevOps team raises before retiring their separate ETL and reverse-ETL tools. [Talk to a solutions architect](https://www.stacksync.com/book-a-demo) ### 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. ## Stop paying for two sync tools. Keep CRM and warehouse in step.
