BigTime vs Certinia
Run Services on Services Software, Not on Your CRM
PSA software your operations team owns end to end.
Certinia puts your services business inside Salesforce, along with its licenses, admins, and release cycles. BigTime PSA runs project economics on its own and connects to Salesforce where you need it.
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 PSA, we can finally get back to running our business.
— Bob Radolph, Chief Financial Officer, Avasant
Here's why 3000+ US-based professional services firms use BigTime
Clear project tracking from scenario testing to payment
Real-time resource and profitability insights
CPQ enhanced by time & expense insights for faster & high-margin quoting
Budgeting that matches how you work—fixed fee, T&M, or custom billing rules
Certinia is known for bringing PSA inside Salesforce…
…but when every change needs a Salesforce admin and every user needs a Salesforce license, services firms find a better fit with BigTime.
Your CRM is built to sell work, not to deliver it profitably.
If your services team waits on Salesforce admins to change a rate, a report, or an approval, it's time to look at BigTime PSA: built for project economics, owned by operations.
