Meet Marianne Salmans, Nuvei's Relationship Management Director

Marianne’s role puts her on the front lines of merchant relationships, especially when the pressure is on during peak seasons.  

For businesses ramping up for Black Friday Weekend, she ensures one thing above all: Nuvei is ready to support, respond, and resolve in real time.

“I help merchants during peak seasons by understanding their business and making sure Nuvei is there to react to their needs.”

What merchants ask for during peak periods

The main question Marianne hears from enterprise customers is a simple one:  

Will the system stay stable?

Whether it’s a large airline like Virgin Atlantic, or a fast-growing eCommerce platform like OnBuy, the concern is universal: Businesses want assurance that their payment flow won’t falter under pressure.  

“Make sure your uptime is 100%. Make sure you can handle the workload. That’s what they ask. And they ask it for a good reason.”

Marianne collaborates closely with Nuvei’s technical teams to confirm transaction volumes, ensure processing capacity, and reinforce system availability during sales events.  

It’s not just about reassurance - it’s operational readiness for the moments that matter most.

What readiness looks like

Marianne draws on her deep industry experience and sees clear best practices for merchants during peak seasons:  

1. Transaction volume forecasting – Ask merchants for expected peaks helps preempt issues. ‍
2. Code freeze policies – Preventing system changes during critical sales windows reduces risk.  ‍
3. Increased monitoring and support – Putting more eyes on performance data and more hands on call ensures swift incident response. ‍
4. Payment flow efficiency – Minimizing unnecessary steps (e.g., 3DS, fraud checks) during checkout can improve conversion during high-traffic moments.

“A complete code freeze might be frustrating, but it works. The rule is simple: Don’t touch the system during peak moments, when it matters most for merchants.”

Beyond December: the January effect

Marianne explains that peak season doesn’t end on New Year’s Day.  

“January often brings a wave of refunds, disputes, and operational follow-ups,” she explains. “That’s when you need to process refunds efficiently. There’s a lot to handle during the aftermath of fraud, chargebacks, or volume spikes.”  

Marianne’s key takeaway:

"The pressure doesn’t stop just because the sale does."

Businesses need a payment partner that’s just as engaged in the aftermath as it is during and before the peak season.
