ROI in The First Billing Cycle

PSA implementations are usually measured in go-live dates. BigTime measures them differently. 
How quickly your billing is accurate, your GL is clean, and your margin is visible.

In-house implementation team

20+ years of PS-specific expertise. No outsourced partners, no handoffs. GL mapping and billing rules configured correctly from day one, across 3,000+ deployments.

Financial-first configuration

Billing logic, rate cards, and GL mapping are set before the first hour is tracked. Every invoice goes out accurate from the start.

The easiest PSA on the planet

Start with your financial foundation. Add resourcing or quoting as complexity grows. Full team adoption within 30–90 days, no training marathons, no unused features.

AI embedded in the financial backbone.
Not layered on top

When AI sits above your workflows, it reports what happened. BigTime’s AI lives inside the financial logic, at the exact moments where firms lose margin, miss billables, and let cash flow drift.
