Faster money helps, but only if the books keep up. Three respondents explain what instant payments changed for their cash flow, and why old processes, fees and cut-off times still slow adoption.

Instant payments are no longer a novelty for businesses. In the UK, Faster Payments carried about 5.55 billion payments in 2025, up 9% on the year before, according to Pay.UK’s annual statistics. Still, instant payments do not fix cash flow on their own. The respondents we heard from found that the payment is the easy part, and the processes around it decide the result.

We asked one question: what has switching to instant or real-time payments changed for your business’s cash flow, and what held back adoption? We wanted CFOs, treasurers and finance leads at businesses, plus payments executives at banks and payment service providers. Real results mattered more than commentary. Three people answered in this round, and we used all three. None runs treasury at a bank or large company, so we’ve set their experience against the latest data.

How far instant payments have spread

The US rail is growing fast from a small base. FedNow settled 6.38 million payments worth $370.9 billion in the third quarter of 2026, up from 2.51 million a year earlier, the Federal Reserve’s figures show. In Europe, the Instant Payments Regulation has required euro-area payment firms to send instant euro transfers since 9 October 2025, Payment Expert explains. Those transfers cannot cost more than a standard one. As a result, instant made up 30.7% of euro credit transfers by volume in the third quarter of 2025, up from 19.7% a year earlier. In the UK, instant payments have been standard for years, so the question there is less about access and more about how firms use the speed.

Fix reconciliation before you switch

Ankit Sarawagi curates CFO Matrix, a finance resource, and describes moving customer payments to same-day settlement.

“The biggest difference has been in customer payments. We’ve gone from receiving cash in two to three days to receiving it the same day. We can see our exact cash position at any time, and if we need to pay a supplier, we can do it that day.

A few things held us back at first. Our customers didn’t know they could pay instantly. Our accounts were also set up to balance once a day, so we’d still have unmatched cash until the next morning. And a few of our suppliers couldn’t accept instant payments. So we changed how we reconcile our accounts to run in real time, and updated all our invoices with the new account details.

It’s hard to measure how much difference this has made, though. We can’t tell whether it’s just because we’re faster, or because we’re paying closer attention to our cash position.”

His blockers are the useful part. Money that arrives in seconds still sits unmatched if the books only balance once a day. So the real change was moving reconciliation to real time and telling customers how to pay. That reconciliation step is where many firms stall. Also, his honesty about measurement is worth keeping. A sharper focus on cash can improve results as much as instant payments do. However, he does not name the business, the country or the rail, so we cannot check his before and after.

Connect payment data to operations

Abhinav Gupta leads Profitjets, an accounting firm that works with US small businesses and their payment data.

“At Profitjets, real-time integration of cash and payment processing, combined with real-time sales and inventory forecasting, improved cash flow for our clients. On average, we cut our clients’ cash conversion cycle by 14 days. Simply adding more payment methods at checkout didn’t improve working capital or margins. To improve cash management, you have to connect payment processing with operational data.”

Abhinav Gupta, Founder, Profitjets

His point backs Sarawagi’s. Faster payments help most when the data feeds forecasts and stock decisions in real time. Otherwise, instant payments simply bring cash in sooner without helping a business use it better. Still, the 14-day figure is his firm’s own, and we found no published case study behind it. Treat it as one firm’s claim rather than a benchmark for instant payments.

Predictable beats fast for some sellers

Conor Smart is a director at Arklavo, a custom apparel business that sells to customers in many countries.

“Instant payouts don’t interest me that much. I run a custom apparel business, so there’s no inventory to worry about. My customers pay by card when they order, and I get the money a few days later. That’s not a problem for me, but if I knew exactly which day and time my money would arrive, I could better plan when to pay for materials and labour.

I have customers in lots of different countries, so it’s not as easy as switching to one of the instant options, because of cut-off times and currency exchange. Plus, the fee would probably be more than I’d save in interest, if that’s even an issue for me.”

Conor Smart, Director, Arklavo

His view is a fair counterweight. For a seller with no stock to fund, a predictable payout date may matter more than speed. His cross-border point also checks out. Stripe’s documentation says its Instant Payouts cannot use multi-currency settlement, and each carries a fee. In addition, it caps each payout at 9,999 in the local currency. That gap matters for exporters, because instant payments work best within one currency and one country’s rail. Arklavo is not a finance business, though, and he has not tested instant payouts himself.

What works for businesses adopting instant payments

The three answers point to a clear order of work. First, move reconciliation to real time, or instant payments will simply create unmatched cash. Next, tell customers they can pay instantly, and update invoices with the right details. Then connect payment data to forecasting and stock planning, as Gupta suggests, so faster cash leads to better decisions. Finally, compare payout fees with the value of earlier cash, and weigh predictability against speed. Firms paying suppliers early face the same trade-off, as our report on C2FO Instant Pay shows.

What to watch next

Reach is the next test for instant payments. Watch non-euro EU states, which must receive instant euro transfers from 9 January 2027 and send them from 9 July 2027. Also watch FedNow’s quarterly growth, since US volumes remain small next to card and ACH flows. In addition, business tools that pay by bank transfer, such as pay by bank, may help more firms take payments instantly.

Above all, instant payments improve cash flow only when the business is ready to use the money. Firms that fix reconciliation and forecasting first will see the gain, while others will simply see the same cash sooner.
