Frequently Asked Questions 

How is BigTime different from traditional Enterprise PSA platforms?

BigTime is purpose-built for modern, growing professional services organizations. We work with clients in consulting, engineering, IT services, and other project-based fields to drive profitable, sustainable growth. 

Unlike legacy PSA systems that are often bloated or rigid, BigTime delivers practical automation, embedded AI, and real-time operational insights—without massive IT lift or absurdly long implementations. Because we work with scaling firms, we prioritize configurability, meaning you can change how you use BigTime as your needs evolve.

What’s the difference between BigTime Enterprise PSA and BigTime Delivery?

Both BigTime Enterprise PSA and BigTime Delivery are PSA solutions, but they’re built for very different levels of operational complexity.

  • BigTime Delivery is designed for smaller firms that need simple but powerful time tracking, invoicing, and portfolio management. It’s ideal for getting up and running quickly with core PSA functionality.
  • BigTime Enterprise PSA is built for scaling and mature firms with more advanced needs, including:
    • Multi-entity and multi-currency support
    • Complex billing models
    • Advanced reporting designed for multiple teams and locations
    • Best-in-class compliance and industry-specific auditability

BigTime Enterprise PSA is the best fit for firms managing large and highly complex portfolios, multiple delivery models, or multiple entities. 

Still not sure? Schedule a 20-minute call with our expert team and we’ll review the best option based on your operations and goals.

How fast can we get up and running with BigTime Enterprise PSA?

For most customers, BigTime Enterprise PSA delivers full go-live in 4-6 months. We offer structured implementation playbooks, live training, and dedicated success teams to help you launch quickly and kick off a long-term plan for success.

What are the top benefits of using BigTime Enterprise PSA?

BigTime Enterprise PSA users see value across four key areas:

  • Higher profitability: Users gets real-time insight into margin, billing, and utilization, leading to greater control and an overage 5% margin improvement in the first year. 
  • Faster month-end close: With built-in invoicing workflows, users accelerate close cycles, taking them from weeks to days. 
  • Improved forecasting: By connecting delivery and sales data, users see up to 30% improvement in the accuracy of revenue forecasts.
  • Scalability: BigTime Enterprise PSA is built to help firms through mergers and acquisitions, growing global operations, and entity expansion. 

How does Enterprise PSA scale with my growing business?

BigTime Enterprise PSA is designed to evolve with organizations as they grow in operations and complexity. 

Key scaling capabilities include:

  • Flexible project modeling: Support for hierarchical project structures, custom billing models, and fund accounting.
  • Multi-entity cost-plus billing: Automates inter-company allocations, markups, and reconciliations.
  • Global readiness: Enables e-invoicing, regional tax compliance, and local billing standards.
  • Configurability: Custom workflows, permissions, and dashboards to match how your business operates—not the other way around.

You can start with a single business unit and scale to a global, multi-entity footprint with confidence.

Can EPSA integrate with my existing ERP, CRM, or PM tools?

Yes. EPSA is platform-agnostic, meaning it is built to work with your existing tech stack and operational processes. 

Built-in integrations include:

  • Services CPQ: Built into BigTime's core platform, Services CPQ connects natively with Enterprise PSA to deliver a unified experience from first quote to final payment.
  • ERP/Accounting: QuickBooks, Sage Intacct, Microsoft Dynamics GP/365, Business Central, Netsuite
  • CRM: Salesforce, HubSpot, Dynamics CRM
  • Project Management: Smartsheet, MS Project, Jira, ServiceNow
  • Productivity/SSO: Google Calendar, Microsoft Outlook, Okta, OneLogin

All integrations are developed and supported in-house, with no need for third-party middleware.

With our old PSA system, we spent way too much time correcting for known inconsistencies in much of our data and questioning the integrity of the rest. With BigTime Enterprise PSA, we can finally get back to running our business.
