3What this role really is

A purchasing assistant helps make sure the right goods arrive at the right time, at the right price. This work involves checking that production does not stall for want of a part or a late delivery. It sits at the centre of how a business keeps running.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

ERP/P2P Platform (e.g., SAP S/4HANA MM, Oracle NetSuite, Coupa) Intermediate

Accurately processing requisitions, creating and tracking POs, performing goods receipts (GRN), and executing three-way matching. You'll navigate standard vendor master data screens with ease.

Microsoft Excel Intermediate

Using VLOOKUP/XLOOKUP, PivotTables, and conditional formatting to track POs, manage supplier lists, and create basic spend summaries. You'll use it for quick data checks and simple reporting.

Collaboration Suite (e.g., MS Teams, SharePoint) Intermediate

Using Teams for daily communication, chasing approvals, and participating in team meetings. You'll upload and retrieve documents from designated SharePoint/Teams folders and manage your own task lists.

Email Client (e.g., Outlook) Advanced

Managing a high volume of emails from suppliers and internal stakeholders, prioritising responses, and maintaining clear communication threads. You'll use it constantly.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Raising a Purchase Order Requires supervisor approval for every PO. Independently raises POs for approved requisitions within budget. Escalates if requisition is incomplete or outside standard process. Independently raises POs, including for complex services or capital equipment. May approve minor deviations from standard process.
Resolving a Three-Way Match Discrepancy Escalates all discrepancies to supervisor for resolution. Independently investigates and resolves standard discrepancies (e.g., missing GRN, minor price variance within tolerance). Escalates complex or high-value issues. Resolves complex discrepancies, including those requiring supplier negotiation or system adjustments. Defines resolution processes.
Supplier Selection for Routine Items Uses pre-approved supplier list only, no selection decision. Selects from a list of approved suppliers for routine items based on price, availability, and delivery, within defined parameters. Cannot onboard new suppliers. Identifies and recommends new routine suppliers for approval. May negotiate terms for smaller, non-strategic suppliers.
Expediting an Urgent Order Informs supervisor of urgent request, supervisor handles expediting. Independently contacts suppliers to expedite orders, communicating any additional costs to the requestor and manager. Cannot authorise extra cost without approval. Strategically expedites critical orders, balancing cost and urgency. May authorise minor expedited shipping costs if within budget and critical.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

PO Processing Time
The average time it takes from receiving an approved requisition to sending out a Purchase Order (PO) to the supplier.
Target · Average < 24 hours for standard POs

If you get 30 requisitions in a week and process them all within 24 hours, you're hitting the target. If one sits for 3 days, that pulls the average down.

PO Accuracy Rate
The percentage of Purchase Orders created without any errors (e.g., wrong quantity, incorrect price, missing GL code, wrong supplier details).
Target · 99.5% accuracy rate

Out of 200 POs raised in a month, you should have no more than one error. Catching the wrong GL code before it hits Finance is a win.

# of Invoices Matched & Resolved
The volume of supplier invoices successfully matched against POs and Goods Receipt Notes (GRNs), and the number of matching discrepancies resolved.
Target · Resolve 50+ invoice queries per week

You'll get a list of invoices that don't match. Successfully fixing 55 of those in a week, by chasing GRNs or correcting POs, shows you're on top of it.

On-Time Delivery (OTD) for Routine Orders
The percentage of your assigned routine purchase orders that arrive by the agreed-upon delivery date.
Target · 95% OTD

If 19 out of 20 standard orders you placed arrived on time, you're doing great. This shows you're picking reliable suppliers and chasing them effectively.

Internal Stakeholder Satisfaction
How happy our internal teams (Production, Warehouse, Project Managers) are with your responsiveness, communication, and ability to get them what they need.
  • You'll know you're doing well when people come to you directly with requests, rather than escalating to your manager. They'll say things like 'Thanks for sorting that out so quickly!' or 'You're always so helpful.' We'll also look at feedback from our quarterly internal surveys.
Supplier Relationship Quality (Routine Suppliers)
The strength and effectiveness of your working relationships with our regular, day-to-day suppliers.
  • Suppliers will respond promptly to your queries and be willing to go the extra mile when there's an urgent request. They'll see you as a reliable point of contact. We'll notice fewer complaints from suppliers about payment delays that are within your control (e.g., missing GRNs).
Problem Resolution Effectiveness
Your ability to independently identify and resolve standard purchasing issues, like a three-way match discrepancy or a slightly late delivery.
  • You're not constantly escalating every minor issue to your manager. You'll demonstrate a clear process for troubleshooting and fixing problems. For instance, you'll spot a missing GRN, chase the warehouse, and update the system without needing to be told.
Process Adherence & Improvement Suggestions
Your consistent application of established purchasing processes and your willingness to suggest small, practical improvements.
  • You consistently follow our P2P cycle, don't raise retroactive POs unless absolutely necessary, and you're the first to spot when someone else isn't following the rules. You might also suggest a small tweak to a form or a communication template that makes everyone's life a bit easier.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Bringing Order to Chaos

You'll get a real kick out of seeing a messy pile of requisitions turn into perfectly processed POs, or resolving a complex three-way match discrepancy. You like systems and making them work.

Successfully reconciling a tricky invoice that's been stuck for weeks, finally getting the supplier paid and clearing it from the system.

Being the 'Go-To' Person

You'll enjoy being the person internal teams rely on to get their orders placed correctly and on time. You'll feel valued when people come to you directly for help, knowing you'll sort it.

A production supervisor thanking you because a critical part arrived exactly when you said it would, keeping the line running.

Contributing to the Bigger Picture

While your work is detailed, you'll appreciate how your accurate processing directly contributes to the smooth running of our entire operation, from manufacturing to finance. You see the link.

Knowing that your diligence in processing a large raw material order on time directly enabled the production of a major client order.

What frustrates people
  • The Approval Chase: Spending an inordinate amount of time chasing budget holders for PO approvals, especially when they were the ones who requested the item urgently in the first place.
  • Garbage In, Garbage Out: Receiving requisitions with vague descriptions, no part numbers, incorrect supplier details, or the wrong GL code, forcing you to do detective work before you can even start.
  • The Scapegoat Syndrome: Being blamed by Accounts Payable for late supplier payments when the root cause was a manager sitting on an approval or a warehouse team not processing the GRN on time.
  • Retroactive POs: The constant battle against 'urgent' requests to raise a PO for an invoice that has already arrived, completely bypassing the proper process. It's a never-ending fight, sometimes.
  • Vendor Data Decay: Dealing with a messy vendor master file full of duplicate entries and outdated information, which makes reporting a nightmare and can lead to errors.
What this role does not give you
  • High-level strategic sourcing or negotiation with major suppliers (that's for more senior roles, at least for now).
  • A quiet, predictable, 'set it and forget it' routine; expect regular interruptions and shifting priorities.
  • The chance to build complex financial models or conduct deep market analysis (though you'll use the data from it).

8Who you work with

This role ensures the continuous flow of materials and services needed for daily operations. Without it, our production lines would stop, projects would stall, and we'd risk damaging critical supplier relationships. You're basically the grease in the gears of our supply chain, keeping everything moving smoothly from order to delivery and payment.

Inside the business
  • Production Supervisors and Engineers
  • Warehouse and Logistics Team
  • Accounts Payable (Finance)
  • Project Managers (for specific project-related purchases)
Outside the business
  • Key Suppliers for assigned categories
  • Logistics and Courier Companies

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • At least 2 years of experience in an administrative, operations support, or junior purchasing role, where you regularly handled data entry, process adherence, and communication.
  • A solid understanding of basic office software, especially Microsoft Excel (VLOOKUP, PivotTables are a must).
  • Experience working with an ERP system, even if it wasn't a purchasing module, so you understand how these systems generally work.
  • Demonstrable ability to follow detailed instructions and processes accurately.
  • Excellent written and verbal communication skills in English.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced ERP/P2P System Navigation & Reporting

The more you know about our ERP, the more efficient you'll be. Being able to pull specific reports or troubleshoot minor system issues yourself will save time and make you more valuable.

Custom Report Generation · System Troubleshooting · Module Interdependencies

  • This month: Ask your manager to show you how to pull one specific report you've always wondered about.
  • Next month: Spend some time in the ERP's training environment (if available) exploring features you don't use daily.
  • Month 3: Document a common ERP error you encounter and the steps you take to resolve it, sharing with the team.

Quick win: Next time you have a question about a specific piece of data in the ERP, try to find the answer yourself by exploring the system before asking a colleague.

Enhanced Microsoft Excel for Data Analysis

Excel isn't going anywhere. Getting better at it means you can handle more complex data sets, perform quicker analyses, and present information more effectively, especially when dealing with supplier quotes or spend data.

Power Query Basics · Advanced Formulas · Data Validation

  • This month: Find an online tutorial for Power Query and try to clean one of your regular data exports.
  • Next month: Identify one repetitive Excel task you do and research if there's a formula or feature that could automate it.
  • Month 3: Ask a more experienced colleague to review one of your complex spreadsheets for efficiency tips.

Quick win: Try to build a simple dashboard in Excel that tracks your personal PO processing metrics for the week – it's great practice.

11Staying current once you are in

What people here do to keep up
  • Attend internal training sessions on our ERP system or new purchasing processes.
  • Seek out opportunities to shadow colleagues in Accounts Payable or the Warehouse to better understand their challenges.
  • Read industry articles or blogs on supply chain management and procurement trends.
  • Join relevant professional groups on LinkedIn to stay connected and learn from peers.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of purchasing work involves repetitive tasks and chasing people. What if you could cut down on that busywork and focus on the more interesting stuff? Our AI productivity tools are here to help you do just that, making your day-to-day a whole lot smoother.

We're not talking about robots taking over your job, but rather smart assistants that handle the mundane, freeing you up for problem-solving and building better relationships. For a Purchasing Assistant, this means less time on data entry and more time ensuring our operations run like clockwork.

PO Creation Automation

Picture this: an approved requisition lands in your inbox, and an AI tool automatically reads it, pulls out all the key details, and populates most of the fields in a draft Purchase Order in our ERP system. It'll even flag any missing bits for you to quickly review. This drastically cuts down on manual data entry.

Invoice Anomaly Detection

Forget sifting through hundreds of invoices for errors. AI can scan incoming invoices against our historical data and your POs, instantly flagging potential duplicates, unusual price hikes, or incorrect quantities. You'll get an alert, so you can focus on the exceptions, not the norms.

Automated Communication Drafts

How much time do you spend drafting follow-up emails? AI can generate standardised, polite-but-firm messages for common scenarios: chasing late deliveries, requesting missing invoice details, or sending POs to suppliers. You just give it a quick check and hit send, saving you loads of typing time.

Basic Supplier Discovery

Sometimes you need an alternative supplier for a standard part. Instead of endless Google searches, AI can quickly scan public data to identify potential new suppliers for specific components, giving you a quick summary of their basic capabilities and contact info. It's a starting point, not the full vetting, but it saves you legwork.
