Still not sure? Just ask Fahem Islam, an Accounting Associate at Snapdocs, who transitioned from using Bill.com for vendor bill payments to Ramp:

“The auto-population that happens with Ramp has been pretty phenomenal. I feel very confident that when I upload a bill into Ramp, it’s going to line up with what the bill says. I spend maybe 10–15 minutes in Ramp every day, and I know that we’re set. That puts my mind at ease -- knowing that I need to put minimal time into Ramp to have it take care of our needs.”

Ramp’s standard plan is also free, making it a cost-effective plan for smaller teams. For companies that need more advanced capabilities, Ramp Plus starts at just $15 per user per month.
