Bill4Time

Bill4Time is a cloud-based time billing platform for professional service firms, covering time tracking, invoicing, and payment processing. It also includes trust accounting features for firms that manage client funds.

Accounting firms use Bill4Time to capture billable hours, generate invoices based on tracked time, and collect payments online. The trust accounting module tracks client fund balances and ensures compliance with fund management requirements — a feature more commonly associated with legal billing software but relevant for accounting firms that hold client funds in trust.

The platform supports multiple billing rates, expense tracking, and detailed reporting on billable vs. non-billable time. It is best suited for small to mid-sized professional service firms that need a dedicated time-to-invoice workflow, particularly those with trust accounting requirements.
