Reports and analytics that show you where you’ve been and where you’re going.

BigTime IQ is equipped with robust reporting and analytics capabilities to keep you informed in real-time. Users can select from an array of pre-installed, customizable report templates, or create them from scratch. Reports can be exported to Excel or PDF, or access our API in order to expand reporting options however you need.


“The fact that the software is industry-specific is helpful because of the flexibility it gives us. We not only can use BigTime for our firm, but for client firms as well. It’s made our office — and our clients’ businesses — run smoother, faster and more efficiently, saving both time and money.“

— Stewart Mueller, CPA, Principal & Owner, Users: 5


“With up to 500 engagements open at any time, we needed a faster and more intuitive way to handle our time and billing. The ease and speed of BigTime’s workflow allowed us to increase productivity, better capture billable hours — and sync to QuickBooks with a single click.“

— Brian Gilmartin, Director of Finance, Users: 200+

BigTime invoicing offers flexible rate structures that are tailored to each client. BigTime IQ allows you to bill time and expenses or retainers, or manually create your own customized invoice. Generate one invoice at a time or create and edit them in bulk, as the software guides you through each invoicing phase from drafting to payment and posting to QuickBooks, and everything in between.

BigTime IQ improves workflow by simplifying creating accounts, managing staff capacity and efficiency, tracking outside expenses and consultants, and drawing all of that data into invoices when you’re ready to bill. This practice management software is equipped with advanced reporting capabilities, budget tracking, and engagement management while simultaneously integrating with QuickBooks and Lacerte®
