Procurement Consultant

About us

Our story so far

It all began in 2017. Armed with 40 years of combined experience, we resolved to set up an alternative procurement company. Why? We wanted to provide our clients with a service that wasn’t available in the marketplace. So we took it upon ourselves to create one. And in July 2017, Aster Commercial was born. Today, we’re proud that our unique approach is now benefiting a wide range of businesses, from FTSE 500 global firms to small local charities.

Meet our owners

Emily Petty

Emily has a lengthy procurement career, covering digital, manufacturing, retail and telecoms. Her roles have been wide-ranging. She has supported long-term strategic programmes from supplier selection through to execution, as well as leading IT Procurement teams to manage the suppliers and contracts associated with significant global organisations.

She has also overseen the management of large commercial relationships spanning end-to-end global supply chains, on and offshore IT Services and key software partners. Recent projects have provided commercial engagement on customers’ supply chain expansion, modernisation and improvement programmes, including the analysis of IT budgets to optimise spend on technology and negotiate agreements that augment supplier engagements and deliver tangible bottom line benefit.

Outside of the day-to-day, Emily can be found keeping fit in the great outdoors, taking in a gig or exploring her next adventure somewhere far flung.

Sarah Walters

Sarah is passionate about all things procurement. Throughout her career Sarah has consistently secured and delivered best value for her clients. Her commitment and drive has ensured impressive results for corporates in OEM, food manufacturing, retail and finance.

With over 25 years’ experience and a CIPS qualification under her belt, she’s highly skilled in the art of supplier negotiation and management across the whole relationship lifecycle. What’s more, she offers you a calm, pragmatic approach in any situation.

When she isn’t working, Sarah loves to be outdoors, preferably by the sea and is also working on developing a series of children’s books.
