Frequently asked questions about Purchasing Assistants


What is the difference between a Purchasing Assistant and a Salesperson?

The difference between a Purchasing Assistant and a Salesperson is the departments they work for and their job focus areas. For example, Purchasing Assistants typically work within the purchasing department. Their job is to monitor inventory logs, order products and check shipments for accuracy. In contrast, Salespeople typically work within the sales department of an organization. They make cold calls to potential leads and notify existing customers of sales or new product offerings. 

Another way to differentiate between a Purchasing Assistant and a Salesperson is that Purchasing Assistants order products to ensure they maintain adequate stock, whereas Salespeople sell those products to consumers.


What are the daily duties of a Purchasing Assistant?

On a typical day, a Purchasing Assistant starts by checking their email and voicemail to see if they have any updates on product needs or budgeting expenses. They review the progress of certain shipments and record estimated delivery times. Throughout the day, they participate in meetings with the purchasing, accounting and sales departments to determine which products did well and didn’t during the previous quarter. 

During downtime at their desk, Purchasing Assistants contact Vendors to renew contracts or order more shipments. They also use this time to research potential new Vendors who offer wholesale products that align with their employer’s needs and price point.


What qualities make a good Purchasing Assistant?

A good Purchasing Assistant is someone who has excellent interpersonal communication. This quality enables them to make meaningful professional connections with Vendors and Wholesalers. They understand consumer trends within their industry and use their knowledge to purchase unique and relevant products. Further, a good Purchasing Assistant should be able to use persuasive language to negotiate shipment prices with Vendors. 

A good Purchasing Assistant should also have a detail-oriented mindset, allowing them to check over order details before placing orders. This ensures they don’t order the wrong type or amount of particular product.


Who does a Purchasing Assistant report to?

A Purchasing Assistant typically reports to the Purchasing Manager within a corporation. These individuals are in charge of relaying information to Purchasing Assistants about budgeting and new Vendors to contact. Purchasing Assistants may also report indirectly to a Purchaser or Buyer who works within their department to help them track orders and contact Vendors.
