Scaling a complex B2B & B2C business: Lessons from a marine retailer

Written by Helen de Souza, Marketing Manager at Maropost | May 19, 2026 6:12:18 AM

Running a successful ecommerce business is challenging. Running one that serves both B2B and B2C customers, manages hundreds of SKUs, and operates across online and physical channels is another level entirely.

That’s exactly the reality for Whitsunday Discount Marine, an Australian retailer that has built a growing, sustainable business in a highly specialised industry.

We spoke with Bruce Goldman, Owner of Whitsunday Discount Marine, about how he’s scaled his business — and what other retailers can learn from his approach.

1. Complexity isn’t a barrier — If your platform can handle it

For many businesses, complexity becomes a growth limiter. But in industries like marine, it’s unavoidable.

Products aren’t simple. They’re technical, often interdependent, and must be configured correctly.

“In the marine industry, customers are very specific. They’re looking for something to go with something else. If you sell the wrong part, it won’t work,” says Bruce Goldman.

For Bruce, managing this complexity wasn’t optional — it was foundational.

The key is having a platform that supports:

  • Product variations and structured catalogues
  • Clear relationships between products
  • Flexibility to adapt as inventory grows
  • Retail customers purchasing directly online or in-store
  • Wholesale buyers including marinas, retailers, and charter companies
  • B2B buyers often discover products online first
  • Retail and wholesale expectations are becoming more aligned
  • Faster order fulfilment
  • Fewer mistakes
  • Better product accuracy
  • An ecommerce store
  • A warehouse with a brick-and-mortar presence
  • A POS system for in-person transactions
  • Consistent customer data
  • Unified inventory
  • Smooth transitions between online and in-person interactions
  • B2B and B2C
  • Online and physical channels
  • Complex product catalogues

Without that, scaling becomes difficult — and error-prone.

2. B2B and B2C are converging

Traditionally, wholesale and retail have been treated as separate channels. Today, they increasingly overlap.

Whitsunday Discount Marine operates across both:

“I sell to marinas, chandlery shops, charter companies, and direct customers. You need a system that can handle all of that,” Bruce explains.

What’s changed is how customers behave:

This means businesses need a unified commerce approach, not separate systems.

3. Inventory accuracy drives customer trust

When products are technical, accuracy is everything.

One of the most interesting takeaways from Bruce’s business is how much emphasis is placed on organisation and labelling.

“Every product in my warehouse has a label on the shelf, and larger products have barcodes and descriptions printed on them. I generate all of that through the system,” Bruce says.

This isn’t just about efficiency — it directly impacts customer experience:

And ultimately:

“I’ve maintained a 100% positive rating on eBay and Google. That comes down to getting the right products to customers and providing good service.”

4. Kitting turns products into solutions

One of the most powerful ways to simplify complex purchasing is through kitting.

Instead of selling individual components, Whitsunday Discount Marine bundles them into complete solutions.

“We sell things like bilge pump kits — that includes the pump, hose, clamps, and fittings. It’s everything the customer needs in one go,” Bruce explains.

Operationally, this also creates efficiency:

“When the order comes through, it prints every item on the delivery docket so staff can tick them off. It reduces mistakes.”

For businesses dealing with complex products, kitting is not just a feature — it’s a growth strategy.

5. The importance of omnichannel operations

Today’s customers don’t think in channels — they expect a seamless experience.

Whitsunday Discount Marine operates:

“I use the POS every day in the warehouse. Customers come in, and I process everything through the system,” Bruce says.

This integration enables:

It’s a clear example of true omnichannel commerce in action.

6. Efficiency comes from flexibility

As businesses grow, so do their operational needs.

Bruce has built workflows that combine platform capabilities with external tools:

“I export data into Excel, use macros or AI, and upload it back. You can update large parts of your system in 20–30 minutes.”

7. Sustainable Growth Is Built on Strong Foundations

Whitsunday Discount Marine has achieved consistent ~10% year-on-year growth, without sacrificing control or efficiency.

“I haven’t had a year where we’ve gone backwards,” Bruce says.

And importantly, that growth is intentional:

“I’m happy growing at around 10% a year. It’s manageable, and it’s sustainable.”

Looking ahead, the focus is clear:

“I’m always looking to grow the product range — adding new lines and improving what we offer.”

Final thoughts: Building for complexity, not simplicity

Many platforms are designed for simplicity. But not all businesses are simple.

For retailers operating across:

The ability to handle complexity is what enables growth.

Whitsunday Discount Marine is a clear example of this in practice — showing that with the right systems in place, even highly specialised businesses can scale efficiently.
