A connected account is a single platform entity that QUANTI: syncs data from. For example: one Google Ads account, one GA4 property, one Meta ad account, one HubSpot portal. It is not a login. A single Google login can give you access to several Google Ads accounts, and each one counts as one connected account. To estimate your usage, add up the distinct accounts you would connect across all your sources. Each plan ships with a quota (Free: 1, Pro: 5, Growth: 15, Expert: 50, Enterprise: unlimited), and you can add more anytime via the Extra Connected Account add-on at 5€ per month each.
