Should you build or buy Project Time Tracking & Billable Hours?
Project time tracking and billable hours software records how employees and contractors spend time across projects and clients, then turns that data into invoices, payroll inputs, and profitability reports. It handles the timer, the project assignment, approval routing, and the accounting handoff.

A timer is only part of a billable-hours system. Compare rate history, approvals, audit records, offline behavior, and accounting synchronization with the subscription. Internal reporting or billing extensions may make sense without replacing the tracker.
Build it, buy it, or bridge?
When building makes sense
Consider an internal build for time capture and reporting for a narrowly defined internal process. A free timer is not the billable-hours and accounting core. Scope integration work and verify current plan limits before comparing costs.
When buying makes sense
Buying earns its keep when you need rate history, approvals, accounting integration, audit records, and ongoing maintenance. Compare the vendor’s coverage with the staff, integrations, and controls an internal option would need. Custom extensions can remain useful without replacing the core.
