Our team sat down with Justin Tettis, Managing Director and Co-founder of Speed Parts, to hear how the company transformed its operations, overcame the chaos of manual ecommerce processes, and scaled to over 700,000 SKUs — all while sustaining 20%+ annual revenue growth.
This is what we learned.
When ecommerce growth outpaces your systems
Speed Parts had already grown into a serious omnichannel player by 2012. With a brick-and-mortar presence, multiple online stores, and active marketplace listings, their catalog was growing fast. But their systems weren’t.
At the time, they were managing tens of thousands of SKUs manually across spreadsheets, eBay, and custom systems. Every product update, pricing change, and order sync required manual effort — and the complexity of automotive fitment data made automation even harder.
“We were doing everything manually — spreadsheets, logging into each marketplace, and trying to keep up,” recalls Tettis. “And when you add the complication of automotive fitment, it becomes a big data set to try and work with.”
Their growth wasn’t just painful — it was unsustainable.
SKU scale needs SKU-native infrastructure
Enter Neto by Maropost, a platform purpose-built for Australian retailers with complex multichannel and inventory needs.
Where other systems failed under pressure, Neto handled Speed Parts’ scale — and added capabilities their custom tools couldn’t.
- 700,000+ SKUs managed in a structured, scalable system
- Automated fitment data support for automotive complexity
- Unified backend for Shopify and Neto storefronts
- Multi-marketplace integrations (eBay, Kogan, Woolworths, Big W)
- Customer group pricing for B2B and retail channel differentiation
Speed Parts didn’t just swap tools — they rebuilt their operations around a platform that was ready for their future.
Multichannel complexity meets operational clarity
Selling the same brake pad across multiple vehicles and platforms isn’t simple — especially when each channel has different requirements. With Neto, Speed Parts streamlined every part of their operation:
- Marketplace templates and channel-specific logic ensured product data stayed accurate and optimized.
- Shipping rules and third-party partnerships enabled automated fulfillment at scale.
- Webstore flexibility meant each storefront could be tailored to specific audiences — with centralized control behind the scenes.
“Neto’s ability to handle large SKU volumes and structured automotive data was a game changer,” says Tettis. “It allowed us to scale efficiently and improve the customer experience.”
Results that move faster than manual ever could
Since implementing Neto in 2018, Speed Parts has transformed from a manually run operation into a tech-forward ecommerce leader. Their results speak volumes:
- Consistent 20%+ annual revenue growth
- SKU expansion from 50,000 to over 700,000
- Ecommerce-first model with a 70/30 revenue split favouring online
- Top-10 eBay automotive parts seller in Australia
And they’re just getting started.
“Neto is like oxygen for our business,” says Tettis. “If it were suddenly gone, it would be a disaster. It’s that critical.”
Preparing for the next million SKUs
With a clear roadmap and the right infrastructure in place, Speed Parts is preparing for its next leap:
- Return to Amazon
- Launch on Bunnings Marketplace
- Expand SKU count beyond 1 million
- Deepen their domestic dominance before going global
Their message is simple: Growth doesn’t have to break your systems — if you start with the right ones.
