Company profile
researched Aug 2026Inbox Health provides patient billing software for healthcare revenue cycle operations. The platform automates patient billing cycles, tailoring the timing and content of billing communications to each practice and each individual patient, and delivers billing messages by email, text message, paper mail, and voice call. Follow-up communications adapt based on how a patient interacted with earlier messages.
The platform also covers patient support and payments. It offers HIPAA-compliant live chat, text, email, and phone support, with AI-generated responses that handle routine issues such as insurance information updates, and an option to fully outsource patient billing support to an Inbox Health team. On the payments side, patients can pay by credit card, digital wallet, ACH, phone, and check, in office or online, and practices can offer automated payment plans. Inbox Health integrates with commonly used practice management systems so patient accounts receivable can be managed centrally.
Business model
Inbox Health sells its patient billing platform to medical billing companies and healthcare practices, and also operates a partner program through which partners can offer a customized, white-labeled patient billing experience powered by Inbox Health.
Traction

Named customers and references include Precise Practice Management, Keystone Medical Management, The Auctus Group, PractiSynergy, and Eyecare Services Partners, an ophthalmology and optometry practice group that a company case study says exceeded its full-year 2024 collections in 8.5 months.
