Source
Merge: What is a Linked Account in Merge?

A Linked Account represents an end customer's authenticated connection to a third-party application (like Salesforce, HubSpot, or Zendesk). Merge pricing is based on the number of production Linked Accounts your end users activate.

Source
Flowise: What is Flowise's Starter plan pricing?

The Starter plan costs $35 per month (first month free) and includes unlimited flows and assistants, 10,000 predictions per month, and 1 GB storage.

Source
Merge: Can I access custom data not in Merge's universal schema?

No. Merge works well for standardized integrations but hits limits with enterprise customers. You cannot access data outside Merge's universal schema, cannot customize integration behavior for specific customers, and cannot pull deeply custom data from source systems.

Source
Flowise: How does Flowise charge for additional users?

Additional users on the Pro plan cost $15 per user per month. The Pro plan supports 5+ users with this per-user add-on pricing.

Source
Merge: What happens if I switch away from Merge?

Merge holds your customers' OAuth tokens. Switching providers means asking every customer to re-authenticate, resulting in potential customer churn and unhappy users.

Merge: Does Merge work with legacy systems?

No. Merge only works if there's an API. Legacy ERPs, government portals, insurance carriers, and older enterprise systems that customers depend on often don't have APIs, making Merge unable to support these integrations.
