Slimstock & Thomax team up on supply chain software

Slimstock ANZ and Thomax have formed a partnership to integrate inventory planning with warehouse and transport management systems across Australia and New Zealand.

The agreement links Slimstock's Slim4 planning software with Thomax's warehouse management system and transport management system, connecting demand forecasting and replenishment planning with warehousing and freight execution.

The arrangement is intended to address gaps between inventory planning and fulfilment operations across eCommerce, third-party logistics, wholesale distribution and omnichannel retail.

The partnership begins in Australia and New Zealand, where both groups will work together on customers that need tighter coordination between upstream planning and downstream delivery. They are also considering expansion into other markets where Thomax operates, including the United Kingdom, the United States and parts of Asia.

System link

Slimstock's Slim4 platform is used for automated forecasting, replenishment, multi-echelon inventory optimisation and integrated business planning. Thomax supplies warehouse and transport software that manages order fulfilment, warehouse workflows and routing.

By connecting the two systems, customers should be able to translate inventory forecasts into warehouse activity and transport decisions with less manual intervention.

The announcement reflects continued investment by supply chain software providers in linking planning systems more closely to execution tools, as retailers, distributors and logistics operators seek to manage volatility, fulfilment complexity and rising transport costs.

In Australia and New Zealand, those pressures have been shaped by labour constraints, dispersed distribution networks and growing expectations for faster delivery across online and store-based channels.

Sheeba Lamba, Regional Partner Manager at Slimstock ANZ, outlined the rationale for the partnership.

"Many businesses have made significant strides in inventory planning, but sustained supply chain performance ultimately hinges on warehouse execution and delivery reliability," said Sheeba Lamba, Regional Partner Manager, Slimstock ANZ.

"By combining Slimstock's inventory optimization expertise with Thomax's WMS and TMS capabilities, we are giving our clients the tools to connect planning directly to the warehouse floor. Thomax's proven track record across 3PL, wholesale, and retail makes them the natural fit to co-deliver smarter, more resilient, and highly synchronized supply chains across ANZ and beyond," Lamba said.

Operational focus

Thomax, which was founded in Australia and operates internationally, supplies warehouse and transport software to businesses in eCommerce, logistics, wholesale distribution and retail. The partnership adds planning intelligence before goods reach warehouse and transport workflows.

Thomas Jackson, Founder & Managing Director of Thomax, said the aim is to improve the flow of stock decisions into fulfilment activity.

"Our priority at Thomax has always been to help organizations achieve faster fulfillment, lower logistics friction, and elevate the customer experience," said Thomas Jackson, Founder & Managing Director, Thomax.

"Partnering with Slimstock brings AI-driven inventory intelligence directly upstream from our warehouse and transport management workflows. This collaboration ensures our customers not only pick, pack, and ship efficiently, but also ensure the right stock is in the right location well before the order drops. We are thrilled to partner with Slimstock to drive end-to-end supply chain transformation," Jackson said.

The companies identified several areas the partnership is expected to address, including linking demand and replenishment planning to warehouse operations and freight distribution, improving stock availability, reducing excess inventory and cutting delays in fulfilment and transport.

They also said a standardised integration model could shorten deployment times for third-party logistics providers, distributors and retailers that want planning and execution systems to work together without extensive custom development.

Slimstock focuses on supply chain planning, including sales and operations planning, demand forecasting and inventory optimisation. Thomax's position in warehouse and transport software gives the partnership a route into businesses seeking a single flow of data from inventory decisions through to order handling and delivery.

For supply chain software providers, such partnerships can be a faster way to broaden product reach without building every system module internally. For users, the appeal often lies in reducing handoffs between planning teams, warehouse managers and transport operators.

The partnership is designed to unify planning, warehousing and logistics execution for customers across Australia and New Zealand, with international expansion under consideration in markets where Thomax already has a presence.
