Faster invoicing does not mean faster payment. That is the argument from David Zwick, chief financial officer at Billtrust, in a PYMNTS eBook called "Payments Leaders Rethink What Works in 2026." He says he used to believe the opposite, and a survey changed his mind.
What he used to believe
Zwick says he spent years pushing his team toward automation. The goals were fewer manual steps, faster processing and cleaner reconciliations, which means matching up records so the books agree. He measured success by shorter cycle times, better staff efficiency and fewer errors when closing the books. He assumed cash would follow efficiency on its own.
What the survey found
Billtrust ran a survey of finance leaders that has not been published yet. Zwick shared several results:
- 67% of finance leaders miss their monthly cash forecast by more than 5%.
- 45% miss their cash forecast by 16% or more.
- 92% run their credit-to-cash process across two or more separate systems.
- 74% agreed that traditional automation "digitized the paperwork but didn't solve cash flow bottlenecks."
Credit-to-cash means the full path from giving a customer credit to collecting the payment. Zwick had assumed forecast misses were a problem for less advanced finance teams, not well-automated ones.
Speed is not the same as cash
His main point is that the two goals only look related on a dashboard. A company can automate every manual step in collecting what it is owed and still have money sitting unpaid. Processing an invoice quickly says nothing about how quickly the customer pays it. The better question, he writes, is how fast earned revenue becomes cash the company can put to work.
What he does differently now
In the fourth quarter, Zwick says he stopped treating automation numbers as a stand-in for financial health. He now asks a second question about any process change: how much faster will it turn earned revenue into usable cash? If the honest answer is that it will not, he no longer counts it as a cash project. It may still be worth doing for other reasons. He says this has changed which projects get called urgent and which get called nice-to-have.
He still backs automation. His view is that it is necessary but not enough on its own.
What to keep in mind
The survey comes from Billtrust, and the results are not yet public. The material does not say how many leaders were asked. Still, the test is easy to borrow. Before buying a billing or invoicing tool, ask whether it gets money into the bank sooner, not just whether it saves time on paperwork.
The takeawayBefore adopting a billing tool, ask whether it gets you paid sooner, not only whether it saves your team time.
