BigTime product overview

BigTime is an online time and billing solution designed to serve professional service firms like accounting, engineering, government contracting, legal and IT services. The integrated solution offers features like time and expense tracking, WIP management, task & workflow management, invoicing, billing and more.

BigTime time tracking captures all time spent on projects or out of office activities through a mobile timesheet app. Employees can submit expenses through the online portal or directly from their mobile devices and attach scanned receipts. Once finalized, the solution automatically generates a digital expense report and submits it to the system for approval.

Users can access the solution on their Android and iOS devices using the BigTime mobile apps. The solution can integrate with various accounting and ticketing solutions including QuickBooks, Slack, Zapier, Salesforce, and more.

Cons of BigTime

Back to top ↑

Users have referenced some features of invoicing and billing could be improved, such as sending invoices to multiple recipients on the same email and persistence of billing rates between invoices and the billing tools. Other reviewers have mentioned that in-app terminology doesn’t match with industry standards, which can make for a frustrating implementation.

Breakdown of core features

Back to top ↑

BigTime software includes several features that are standard across time tracking and billing tools.

Time Tracking

Meetings and emails are the black hole of lost time. BigTime’s mobile timesheet app for remote and offline time and expense tracking captures more information from every meeting. Use smart lookup fields to speedup timesheet entry. Spend less time on tracking and bill more time.

Expense Tracking

BigTime offers flexible expense tracking for mileage and receipts on the go. Capture a stack of paper receipts with your smartphone and attach them to your digital expense report. BigTime’s expense tracking tools let you bill earlier, track accurately, and stay on top of expenses any time at all.

Project Management

Track the things that are important to you. Deep dive into project tasks and budgets. Check the status of tasks by due dates, staff assignments and more. If you’re operating blind, real-time visibility is a few clicks away – and exactly the way you want to see it.

Billing & Invoicing

Keep your clients happy with invoicing that is accurate, timely and well documented. It doesn’t matter how you bill: time and material, multiple fixed-fees billed at milestone or percent complete. BigTime has customizable invoicing templates that deliver as much or as little detail as your client wants to see.
