Stacksync
Stacksync is a data sync tool that keeps records in CRMs such as Salesforce and HubSpot, ERPs such as NetSuite and SAP, and databases such as Postgres in step in real time, in both directions, for engineering and RevOps teams who don't want to maintain custom integrations.
Updated October 2026
Overview: What is Stacksync?
Starter costs $1,000 a month billed annually for one sync and 50,000 records (checked October 2026).
You connect two systems, map the objects and fields, and Stacksync keeps them matched: a change in Salesforce shows up in Postgres and the other way round, with conflict handling and backfill. That lets engineers read and write CRM data with SQL instead of building against each CRM's API. It also runs event-triggered workflows and retries failed ones. For a revenue team it's the plumbing that keeps the CRM, billing system and product database agreeing on the same customer.
Fit: Ideal customer profile.
Companies with an engineering or data team that needs CRM, ERP and database records kept in real-time agreement, and that would otherwise build and maintain those integrations in-house. At $1,000 a month and up it's built for serious data volumes; a small team syncing a few fields between two SaaS apps can use a cheaper automation tool.

Usage
How to use Stacksync.
Stacksync starts with a guided proof of concept led by its integration engineers, who validate the use case and configure the first sync. You pick the two systems, choose objects and fields, set direction and write permissions, then turn the sync on. A HubSpot app is listed in the HubSpot marketplace. The Managed Pro plan hands ongoing implementation and maintenance to Stacksync's own engineers.

Questions
Frequently asked.
How much does Stacksync cost?
Starter is $1,000 a month billed annually ($1,400 month to month), Pro $3,000 and Managed Pro $4,200, with Enterprise quoted. Extra records are billed per 1,000 (checked October 2026).
Does Stacksync work with Salesforce and HubSpot?
Yes. Both are among its 1,000+ connectors, and a common setup is a real-time two-way sync between Salesforce or HubSpot and a Postgres database.
What counts as a synced record?
A record counts once per month when it's present at the start of the month or syncs for the first time. Updating it again doesn't cost more, and records aren't double-counted across apps.
What are Stacksync's limits?
The entry price suits teams with real data volume, Starter covers only one sync between two apps, and logs on Starter last one day. Two-way sync still needs careful field mapping and write rules so one system doesn't overwrite good data in another.
What are the alternatives to Stacksync?
Hightouch and Census push warehouse data into business tools, Syncari syncs and governs GTM data, Whalesync handles two-way sync for no-code apps, and Workato is a broader integration platform.
