Wacek & Associates

Increase efficiency in QuickBooks like Wacek & Associates

"BigTime has helped us increase efficiency from start to finish. From onboarding a client to actually doing the work for them, drafting the invoice, and sending it to them, because of the cohesiveness of the program we're able to increase our efficiency in how we serve the client and how we bill them."

PLATT Architecture

Get paid faster like PLATT Architecture

"BigTime Wallet offered us a way to get payments faster from our clients, and also eliminate any fees within electronic payments on the client end. The ease of creating invoices from time in BigTime and the formats were better than almost anything we’ve seen out there."

Increase productivity by 66% like Draper and Associates

"We were taking 60 days from the end of a period to get time and expenses in, approved, and the invoices out. Now, [with BigTime] we’re down to about 20 days."

Andrew Rossman

Globiox

Seamlessly scale without growing pains like Globiox

"We have a bunch of tasks and subtasks for each one of our projects and a huge improvement that I've seen is less questions about, “What am I supposed to be doing?” on a project. So not only does it keep time for that task, but you can also identify the task that someone needs to work on and push it out through BigTime."

Ingrid Jansen

Ardalyst

Flip a switch to become DCAA compliant like Aradlyst

"People are always surprised when I talk to them about just how fast it is. We enforce time entry by midnight of the last day of the month, and the next morning managers approve the time, and we start generating invoices by lunchtime, get the approval, and get them out to the client by the end of the day. It's that fast."

Brandy Thill

VP of Operations, North Labs

Increase revenue by 25% like North Labs

"BigTime has saved us money by being more efficient, it's helped us to be able to grow and expand, and now we’re seeing more revenue come in. From that, we can go after more deals which is obviously (happy face!) it’s all just kind of like that spiral."
