Commercial Cards Put Cash-Flow Float Back in Play
Businesses have long treated accounts payable as a back-office chore. That thinking is changing fast. A growing wave of companies is turning to commercial cards as a strategic tool for B2B working capital management, and the results are reshaping how CFOs think about liquidity.
At the heart of this shift is a model known as buyer-funded B2B card payments, where the buyer, not the supplier, absorbs the transaction fee. It sounds like an odd trade-off at first, but the economics tell a different story. By paying suppliers via card and stretching out the settlement window, buyers can extend their days payable outstanding while keeping supplier relationships intact, all without taking on traditional debt.
David Bork, Senior Vice President of Boost 100 at Boost Payment Solutions, said the logic becomes clear once you look at the numbers. “Now you’ve got this weapon that you can use as a buyer to uniquely manage cash flow. You can preserve liquidity, and now you’re using credit intentionally as a working capital tool,” he told PYMNTS.
What makes this model particularly attractive is that many companies already have the infrastructure in place. A commercial card program through their existing bank is often all they need to get started. For treasurers under pressure to squeeze more out of every dollar, that low barrier to entry matters.
The commercial cards B2B working capital approach also carries a meaningful accounting advantage. Card spend typically falls under trade payables rather than long-term liabilities, meaning companies can access liquidity without inflating their debt load, a critical distinction in today’s capital-constrained environment.
Bork cited one company processing $50 million per month with a single supplier through Boost 100. The freed-up liquidity was then redeployed to capture early payment discounts from other vendors, creating a compounding financial benefit.
Even friction from suppliers reluctant to accept cards is no longer the dealbreaker it once was. New payment structures can route transactions to appear as standard ACH or wire transfers on the supplier’s end, while the buyer still benefits from card-based financing behind the scenes.
Cross-border payments are the next frontier. Models like Boost 100XB process card transactions domestically before settling via ACH or wire internationally, extending the same commercial cards B2B working capital benefits to global supplier networks, without the usual network fees.
Bork described the end goal plainly: a system that is “repeatable, scalable and secure, where there’s no friction in the transaction anymore.” For finance teams still treating AP as a cost centre, the message is clear, the float is back on the table, and commercial cards are the reason why.
