Invoices Overdue by 60-days?

Let’s Fix That. At Zero Cost.

Sick of Excuses? We’ll Do the Chasing.
You Stay Focused on Your Business.

At 60 days overdue, it stops feeling like a simple delay.

You’ve followed up. You’ve been reasonable. You may have had promises, or just total silence.

Either way, something has shifted.

What used to be a straightforward invoice is now sitting in that uncomfortable space between “it’ll get paid” and “this is becoming a real problem”.

And that uncertainty starts to wear on you.

Do you keep chasing?
Do you push harder and risk the relationship?
Or do you wait and hope it resolves itself?

This is where most debts quietly drift further out of reach.

Sentinel steps in at this exact point.

We take over the process professionally, without friction, and without costing you anything. We handle the follow-ups, the pressure, and the escalation if needed, so you don’t have to.

Because at 60 days, the outcome is still in play.

What happens next depends on what you do now.

Meet The Founder

Hi, I’m Karl, the person behind Sentinel, a debt collection agency here in NZ.

I’ve spent over three decades helping small businesses solve hard problems – from financial recovery to operational systems. Sentinel was born out of frustration with how traditional debt collection works: slow, expensive, and impersonal.

We do things differently. We’re direct, respectful, and relentless – and we never charge you a cent. Ever. That’s not marketing. That’s our model. Our promise to you.

You’ll deal directly with a dedicated collection specialist, or with me. Every case is handled with the same care I’d expect if the roles were reversed.

Sentinel: We chase the money so you don’t have to. And it costs you nothing.

Debt Collection. Professional.
Ethical. Zero Cost.

Professional

Recovering overdue debts isn’t just about sending reminders.

At Sentinel, we specialise in commercial debt recovery – handling the entire process from initial contact through to legal escalation if needed.

You stay focused on your business. We chase the money.

Ethical

We act with integrity, always.

Debt collection in New Zealand isn’t licensed, but the Fair Trading Act and Commerce Commission guidelines still apply.

That means no harassment, no shortcuts – just a fair, firm process that respects everyone’s rights.

Zero Cost

You’ll never pay us a cent.

There are no upfront fees, no admin fees, no commissions, and no fine print.

Whether we recover the debt or not, you pay nothing.*

That’s not a promo. It’s our business model.
