Reasons clients leave an agency
Clients name delivery and value. Their marketing chiefs are also cutting agency budgets, and the first cut is the agency they can't see working.

Client reporting and communication

The pattern across these studies
Clients don't leave over one bad month. They leave when they can't see the work behind the invoice. Setup's clients rank delivery and value first, Gartner's CMOs cut the agency relationships they call unproductive, and CallRail finds the shortest client relationships at the agencies that report least.
None of these studies tested a client portal, and this page doesn't claim they did. They agree on one thing: the client's view of the work decides the renewal as much as the work does.
Method and sources
A figure made this page only when its study opened and showed the number. A blog post that quotes a study didn't count, so each link above goes to the publisher's own report, press release or research page.
Most of these are vendor surveys. CallRail, AgencyAnalytics, Predictable Profits and Asana sell to the people they surveyed, and Client Glance sells client portals to agencies too. Read the sample line under each figure before you lean on it: 100 agency professionals is a small sample.
Client Glance ran no survey of its own. It has a small customer base, too small to say anything about the market.
Figures left out

- "28% of clients leave over a lack of communication": quoted without a named study.
