Why Does Professional Services WIP Keep Getting Left Unbilled?
Professional services firms lose more revenue to billing gaps than to bad clients. Time entries that never get invoiced, retainers that lapse, milestones that slip past without a bill — these invisible leaks compound into six-figure losses every year.

How Does Singoa Automate WIP Billing?
Four purpose-built modules covering the full professional services billing lifecycle — from WIP aging through retainer management, timesheet billing, and project profitability.
Zero Unbilled Hours — Guaranteed
Every approved hour is tracked, aged, and surfaced for billing. Singoa pulls time entries from your PSA system, identifies WIP that's ready to invoice, and flags hours at risk of write-off before they age past your billing policy.
- Live WIP balance dashboard by project, client, partner, and timekeeper
- WIP aging buckets: current, 15d, 30d, 60d, 90d+ with write-off risk scores
- Unbilled hours alert: approved entries not yet invoiced after configurable threshold
- Auto-invoice draft generation from billable WIP on billing cycle date
- Write-down and write-off workflow with partner approval and reason capture
- WIP turnover rate tracking — portfolio-level billing efficiency metric
- Client billing cap enforcement: flags hours exceeding budget thresholds
