Best time off management for consultants

There are roughly 40-60 general PTO management tools on the market (Namely, BambooHR, Guidepoint, etc.), but almost none are built specifically for the consulting vertical's unique demands: billable hour tracking, client-based schedules, bench time management, and capacity planning across projects. The common failure is that generic HR tools treat time off as an administrative checkbox rather than a revenue and capacity problem. Consulting firms lose 15-25% of potential billable hours annually through poor time-off visibility and scheduling conflicts. The real gap is that consultants operate in a matrix—they're allocated to multiple clients simultaneously, have varying project end dates, need bench time visibility for sales pipelines, and require forecasting that ties time off to revenue impact. A new shipper should build specifically around project-based allocation, not just headcount absence. The opportunity sits at the intersection of project management and HR, where time off becomes a capacity constraint that directly affects client delivery and margins. Most existing tools force consultants into workflows that don't match how consulting actually works.
