ELT and reverse-ETL are the same primitives in opposite directions. Running two tools doubles the cost, the integrations to maintain, and the places to debug. 01 - Connector duplication ### You pay twice for every system Fivetran charges per source; Hightouch charges per destination. Most systems show up on both lists, so you pay for the same Salesforce connector in two SKUs. COST 02 - Observability split ### When a sync breaks, which tool's UI do you open? A row went into the warehouse but didn't come back to the CRM. Was it Fivetran's fault, Hightouch's, or the model in between? Three SaaS apps to check, three sets of logs. DEBUGGING 03 - Latency ### Round-trip is hours, not seconds Fivetran syncs hourly. Your dbt models run nightly. Hightouch ships every 30 minutes. End-to-end latency from source change to operational tool is measured in hours. FRESHNESS PLATFORM ## Six products. One Platform. Replace many legacy vendors. Every tool Stacksync replaces is one fewer vendor, one fewer bill, one fewer integration to maintain.

ETL/reverse-ETL questions are about coexisting with dbt, end-to-end latency, migrating from Fivetran + Hightouch, and pricing. [Talk to a solutions architect](https://www.stacksync.com/book-a-demo) ### Can we keep using dbt? Yes. Stacksync reads from dbt models like any other warehouse table. Your transformation logic stays in dbt; Stacksync handles the operational sync layer on top. ### How fast is the round trip? Source change to warehouse: 1–60 seconds depending on connector (CDC where available). Warehouse model to operational tool: sub-second to a few seconds. End-to-end is typically under 10 seconds, vs. hours with separate tools. ### What happens to my Fivetran / Hightouch deployment? Most teams migrate incrementally, run Stacksync alongside in the validation period, then cut over connector by connector. Migration scripts are available for both source and destination configurations. ### How is pricing different? Stacksync prices on records moved, not per source/destination connector. So syncing the same connector both directions counts the data once, not twice. ## Your last integration took months. Your next one takes a prompt.
