What the pricing really means
At first glance, Grow Therapy looks cheaper at $0/month vs $35/month. But sticker price is only part of the story. Look at what is included on the base plan, how many users you get, and whether you need add-ons to get the features you actually need. The $99/month plan that requires $200 in add-ons is actually more expensive than the $250/month plan that includes everything.
Where Grow Therapy wins
- Free platform with full EHR, telehealth, and managed insurance billing
- 100+ insurance plan partnerships including Medicaid in select states
- AI-assisted documentation built in
- 4.7/5 on Trustpilot with 7,500+ reviews — more than most EHRs
Where WriteUpp wins
- 30-day free trial with no credit card required, so you can test with real patients before paying anything
- 1,000 free video minutes included on Solo and Group plans, which saves the cost of a separate telehealth tool
- 47,000+ clinicians use it, mostly in the UK, so there is a real user community for support and advice
- GBP pricing starts at just 19.95 pounds per month on the Flex plan, making it one of the cheapest options for UK practitioners
Where Grow Therapy falls short
- No presence on G2 or Capterra makes independent comparison harder
- Commission model means lower per-session take-home than billing yourself
- Similar to Headway — you trade independence for convenience
- Not designed for group practices
Where WriteUpp falls short
- Not HIPAA compliant, so US-based practitioners cannot use it for patient data
- Only 7 reviews on Capterra and 14 on G2, which is too thin to trust ratings at face value
- No dedicated mobile app, so you are using the browser on your phone which is not the same experience
- No API access, which means you cannot automate workflows or connect to custom tools
- Billing and reconciliation are clunky according to multiple user reviews
