The Modern BigTime Alternative.For High-Yield Professional Services.
An effective BigTime alternative must deliver professional services automation (PSA) and project accounting without the overhead of tiered contract lockouts, opaque renewal pricing, and sluggish user interfaces. TimeTrackerOn provides full-lifecycle Work-in-Progress (WIP) tracking, flexible multi-tier rate cards, automated AIA G702/G703 billing schedules, and bi-directional General Ledger synchronization—giving consultancies and A&E firms complete financial control on a transparent, predictable per-user model.
WIP tracking, progress billing, and multi-tier rate schedules available on standard plans without enterprise surcharges.
Move active projects, rate cards, and client rosters over a single weekend rather than enduring multi-month consulting deployments.
Simple, predictable per-seat licensing without mandatory multi-year contract renewals.
Stop Paying for Enterprise Upgrades Just to Access Essential PSA Features
BigTime segments its platform into tiered packages (Express, Pro, Premier, and Projector). Critical capabilities such as resource allocation, multi-level approvals, and custom invoice calculations are locked behind costly upper tiers.
- All Core Capabilities Included: Enjoy dynamic Work-in-Progress (WIP) tracking, multi-tier approval chains, and customizable invoice templates without forced tier upgrades.
- No Forced Annual Auto-Renewals: Retain complete commercial flexibility with transparent month-to-month or discounted annual billing.
- Unlimited Projects & Clients: Manage your entire client portfolio without worrying about artificial usage limits or tiered license tiers.
Transform Verified Timesheets into Client Invoices in 60 Seconds
Drafting invoices in BigTime often requires navigating multiple separate screens, adjusting line items manually, and running static reports to verify whether a project is within budget.
- Real-Time WIP Ledger: Unbilled labor and verified project expenses populate directly into our time and billing software WIP engine, eliminating manual reconciliation.
- Native AIA G702/G703 Progress Billing: Generate certified payment applications and continuation sheets for architecture and engineering firms automatically, complete with retainage tracking.
- Not-to-Exceed (NTE) Fee Guardrails: Automated alerts flag when logged hours hit 80% and 100% of agreed contract caps before invoices are sent to clients.
Bi-Directional General Ledger Synchronization That Eliminates Re-Keying
BigTime's accounting synchronization often requires manual sync triggers or surface-level journal entries that lack granular departmental context.
- Full Dimension Mapping: Synchronize hours, expenses, and project billing across all eight standard dimensions via our native Sage Intacct integration.
- Unified Spend Management: Capture employee out-of-pocket receipts and reconcile corporate card feeds alongside billable hours using our integrated expense management software and AP automation software.
- Two-Way Payment Reconciliation: Automatically update invoice payment statuses in TimeTrackerOn when client checks or ACH transfers clear in your core accounting system.
Frictionless Time Capture That Drives 100% Weekly Timesheet Compliance
Complex desktop interfaces and slow mobile apps discourage staff from logging time contemporaneously, resulting in late timesheets and estimated hours.
- 1-Tap Mobile & Desktop Timers: Team members can start, stop, and switch tasks in seconds across web, macOS, Windows, iOS, and Android.
- Turnkey Phase Code Hierarchies: Pre-load standard project phases (e.g., Schematic Design, Construction Administration) to eliminate confusing task menus.
- Field Kiosk & GPS Geofencing: Support both desk-based consultants and field crews with automated location validation and mobile timecard verification.
