When Mango first implemented OneBill, they had around 800 customers. As they grew—ultimately surpassing 11,000 customers—it became clear that OneBill’s support and product limitations were holding them back.
"We knew we were going to continue to grow," said Brittany Olkjer, Director of Operations. "But we hit a ceiling with OneBill."
The issues weren’t minor. OneBill lacked basic visibility, forcing Mango to manually track overdue accounts, often finding out months later that a customer hadn’t paid. This delayed revenue collection and made it impossible to forecast accurately.
Support was another significant pain point. OneBill’s offshore support model led to poor response times, language barriers, and an overall frustrating experience:
“When we needed help, we didn’t have it. Or, they would give us a response that didn’t make sense. It was very hard to communicate,” Brittany said.
As Mango continued to scale, it became clear: OneBill wasn’t a tool that was going to support their growth.
After a thorough evaluation process, Mango ultimately chose Rev.io as its new billing and revenue management platform. From the start, Rev.io’s U.S.-based support and purpose-built platform stood out.
"The collection side was a huge game changer. We can now see who hasn’t paid right away and act on it,” Brittany said. Unlike OneBill, Rev.io delivered the functionality and partnership Mango required to scale its business.
Key benefits included:
Automated Collections & Visibility: With Rev.io, Mango could instantly see who was past due and act quickly, eliminating the revenue leakage that had plagued them. "Now we know the day after," Brittany emphasized. "It makes a big difference."
Modern Customer Portal: Customers can manage payments and update information directly, reducing support load and improving satisfaction.
Scalable Infrastructure: Tagging, reporting, and account hierarchies (like parent/child relationships) gave Mango the tools to operate efficiently at scale, something OneBill lacked entirely.
World-Class Support: With Rev.io’s responsive, U.S.-based team, Mango feels genuinely supported. Their team now benefits from fast response times, regular check-ins, and a dedicated account management team focused on helping resolve issues quickly, freeing Mango to focus on growth.
One of the most striking outcomes after switching to Rev.io was Mango’s explosive revenue realization.
"When we signed the contract, we thought we would increase billings by 25% throughout the year," said Brittany. "We hit it in two months."
This wasn’t just growth; it was accelerated recognition of revenue that had previously been slipping through the cracks. Rev.io’s visibility and automation allowed Mango to collect faster, invoice more accurately, and align billing with operations seamlessly.
The switch also made it easier to manage their rapidly growing client base. When switching to Rev.io, Mango was at 7,000 customers and were able to seamlessly expand to 11,000 internationally.
“Now we’re set up. We’re growing like crazy, and we’re expanding internationally this year,” Brittany said.
Brittany’s advice to others evaluating platforms like OneBill?
Involve your entire team early to ensure every department’s needs are considered, and don’t just assess what you need today; pressure test for where your business is headed. “We brought everyone into the sales demo and hit Rev.io with every scenario we could think of.
It was important to know the platform could support our future, not just our present.” She added, “Making the switch ahead of our biggest growth wave was key. It’s a big lift, but when you choose the right partner—like Rev.io—it’s absolutely worth it.
