Clients Owe You Money?

Let’s Fix That. At Zero Cost.

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

For small business owners, unpaid invoices can feel personal.

It’s not just about the money; it’s about wasted time, broken promises, and mounting pressure that chips away at your focus and confidence.

When someone refuses to pay, it’s more than a cash flow issue. It’s a breach of trust. And in today’s climate, every unpaid debt can have ripple effects that impact your staff, your clients, and your ability to plan ahead.

Sentinel was created to flip the power dynamic.

We give you a way to fight back – professionally, ethically, and without it costing you a cent by using our debt recovery services.

Our team steps in as your advocate. We do the chasing, the follow-ups, the paperwork, and, when necessary, the escalation. We don’t bluff. We don’t stall. We just get on with it, so you can get back to doing what you do best.

Because you deserve to be paid. And your time matters too.

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.
