Denise Leleux has worked in financial services for more than two decades, but it’s a detour to Tesla’s marketing department that sparked an idea as to how accounts receivable and supply billing can take lessons from the transportation market.
“Who doesn’t want to take Uber of Lyft because you don’t have to worry about the cash or card?” said Leleux, who’s been senior vice president of supplier services at AvidXchange for about a year and is helping to lead a major B2B expansion project.
B2B payments are a large, clunky market that’s attracting the interest of the largest banks, fintechs and payment companies, all wanting to swap out the legacy payment systems that most small to medium-sized businesses with something that resembles a consumer’s mobile experience.

The same challenge afflicts the fintech and payment automation industries, Leleux said.
“Banks are very tried and true and have the trust of their customers,” she said. “Fintechs are creating disruption but don’t have the distribution.”
The Charlotte-based AvidXchange’s strategy for the next year is to build a network of buyers and suppliers that enables digital payments through AvidXchange’s paperless accounts payable and invoice management software.

“eBay taught me about a marketplace of buyers and sellers, with eBay in the middle,” Leleux said.
AvidXchange is part of a large market that's trying to modernize supply chain payments, particularly among small businesses, which make up 44% of U.S. economic activity, according to the

To reach smaller businesses, other firms are partnering up.
“The partnerships between fintechs and financial institutions is a marriage we’re all catching on to,” Leleux said.
