3What this role really is

A Buying Assistant handles day-to-day purchasing, making sure goods and services arrive on time, in the right quantity, and at the right price.

4What you'd actually use

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

SAP S/4HANA or Oracle NetSuite (ERP/P2P) Intermediate

Creating Purchase Requisitions (PRs) and Purchase Orders (POs), tracking order status, and running standard reports like 'open POs by supplier'. You'll be in this system all day, every day.

Coupa / SAP Ariba (eSourcing Platform) Basic

Retrieving quotes or supplier information, maybe helping to upload supplier responses under supervision. You'll be a user, not a builder, of this platform.

Power BI / Tableau (Spend Analytics) Intermediate

Navigating pre-built dashboards to find spend data, applying filters, and exporting data to Excel for further analysis. You'll be a regular user of these insights.

DocuSign CLM / Icertis (CLM) Basic

Locating existing contracts, checking key dates, and routing standard agreements for e-signature. You'll use it to manage existing agreements, not create new ones from scratch.

Microsoft Excel Intermediate

Using VLOOKUP/XLOOKUP, PivotTables, and conditional formatting to organise and report on PO data, supplier quotes, and track your open tasks. You'll use it for data manipulation and simple analysis.

MS Teams / Slack (Collaboration) Intermediate

Participating in team channels, responding to direct messages from internal stakeholders, sharing files, and joining calls. It's how we keep in touch and get quick answers.

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
Purchase Order Creation Creates POs under direct supervision; all details double-checked by manager. Independently creates standard POs; escalates non-standard terms or high-value items for approval. Approves high-value POs within category strategy; delegates standard PO creation.
Supplier Selection (for routine items) Selects from pre-approved list under guidance. Selects from pre-approved list and can propose new suppliers for manager review based on clear criteria. Identifies and qualifies new suppliers for category; makes recommendations for preferred suppliers.
Invoice Discrepancy Resolution Flags discrepancies to manager; assists in gathering information. Investigates and resolves routine discrepancies directly with suppliers and Accounts Payable; escalates complex issues. Defines processes for resolving common discrepancies; handles escalated, complex cases.
Process Improvement Suggestions Identifies minor inefficiencies in own workflow. Proposes specific, actionable improvements to P2P processes for manager review. Leads small-scale process improvement projects within a workstream.

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 Accuracy Rate
The percentage of Purchase Orders you create that are completely correct, meaning the right supplier, price, quantity, and accounting codes.
Target · >99.5%

Out of 200 POs raised last month, only one had a wrong GL code. That's a 99.5% accuracy rate, which is spot on.

Requisition-to-PO Cycle Time
How quickly you turn an approved internal request (requisition) into a live Purchase Order in our system.
Target · < 48 hours for standard requests

A request came in at 10 am on Monday, and the PO was sent to the supplier by 2 pm on Tuesday. That's well within our 48-hour target.

Invoice Query Resolution Rate
The percentage of supplier invoice discrepancies (e.g., price mismatches, missing GRNs) that you manage to sort out within a set timeframe.
Target · 90% resolved within 5 business days

We had 20 invoice queries this period; you fixed 18 of them within five days. That's 90%, meaning our suppliers aren't waiting too long for their money.

Supplier On-Time-In-Full (OTIF) Rate (for your categories)
Tracking how often suppliers in your managed categories deliver the right goods, in the right quantity, on the agreed date.
Target · Improve by 2-3% annually

For office supplies, the OTIF was 92% last quarter. You worked with the supplier, and this quarter it's 94%. Good work!

Stakeholder Satisfaction
How happy our internal teams are with the support you provide, especially around communication and problem-solving for their purchasing needs.
  • They'll proactively thank you for sorting out a tricky order. They'll come to you for advice before submitting a request. They won't be constantly chasing you for updates.
Process Adherence & Compliance
Your ability to consistently follow our established procurement policies and procedures, especially around approvals and supplier selection.
  • Audits show no 'maverick spend' in your areas. All POs have proper approvals. You can clearly explain why you did something in a specific way, backed by process.
Proactive Problem Solving
How well you spot potential issues (like a supplier delay) before they become big problems and take steps to fix them.
  • You flag a potential delay to an internal team before they even realise it. You've already got a backup plan or alternative supplier in mind when you report a problem.
Supplier Relationship Quality (Operational)
The quality of your day-to-day interactions with suppliers, ensuring they feel valued but also held accountable.
  • Suppliers respond quickly to your emails. They're willing to go the extra mile for you when there's an urgent request. They bring issues to you directly, rather than escalating.

7Would you like it

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

What people enjoy
Making a Tangible Impact

You'll get a real kick out of seeing your efforts directly result in a smooth delivery or a problem being sorted quickly. It's about getting stuff done and seeing the outcome.

Sorting out a delayed component shipment that was holding up production, and getting a thank you from the Operations Director.

Problem Solving & Investigation

You enjoy the detective work involved in figuring out why an invoice doesn't match a PO, or tracking down a missing delivery. It's like a puzzle every day.

Successfully reconciling a tricky 3-way match discrepancy that had stumped others, saving us from a payment hold.

Structured & Predictable Work (mostly)

While there are always 'urgent' requests, you appreciate having clear processes and systems to follow for most of your work. You like knowing what's expected.

Efficiently processing your daily batch of Purchase Requisitions, knowing exactly the steps to follow for each one.

What frustrates people
  • Chasing vague requisitions that just say 'new laptop' without any specs.
  • Dealing with the daily 'emergency' from a stakeholder who completely failed to plan.
  • Being seen as just a 'PO pusher' rather than someone who adds real value.
  • Trying to maintain a clean supplier master file when everyone keeps entering duplicates.
What this role does not give you
  • High-level strategic sourcing or complex contract negotiations (not yet, anyway).
  • A quiet, uninterrupted work environment (expect regular pings and urgent calls).
  • Complete autonomy over budget or supplier selection (there are processes for a reason).
  • A role where you're constantly innovating new processes (you'll be following established ones).

8Who you work with

This role directly supports the operational continuity of various departments by ensuring timely and accurate acquisition of goods and services. You're essentially the gatekeeper for a significant chunk of our operational spend, making sure we're getting value for money and staying compliant.

Inside the business
  • Internal Requisitioners (e.g., Marketing, IT, Operations)
  • Accounts Payable team
  • Warehouse & Logistics
  • Finance Business Partners
Outside the business
  • Key suppliers (operational level)
  • Freight Forwarders
  • Third-party service providers

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, purchasing, or supply chain support role, where you've regularly processed orders or managed data.
  • A solid grasp of basic accounting principles, especially around invoices and payments, so the '3-Way Match' makes sense to you.
  • Proven ability to use an ERP system (like SAP, Oracle, or similar) for transactional tasks, even if it wasn't specifically SAP S/4HANA.
  • Experience dealing with external suppliers or vendors, including chasing information or resolving minor issues.
  • Demonstrable experience with Microsoft Excel (VLOOKUP, PivotTables) for basic data manipulation and reporting.

10What to practise next

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

Data Visualisation & Dashboard Creation (Intermediate)

Moving beyond just viewing dashboards to being able to build your own simple visualisations to answer specific questions. This helps you present insights more clearly and spot trends faster.

Choosing the Right Chart Type · Data Storytelling · Interactivity in Dashboards

  • This month: Complete an online tutorial on Power BI or Tableau fundamentals, focusing on creating basic charts.
  • Month 2: Try to recreate one of our existing internal reports as a simple interactive dashboard.
  • Month 3: Propose a new, simple dashboard that could help your manager or internal stakeholders track something useful.
  • Month 4: Get feedback on your dashboard and iterate on it, making improvements based on user input.

Quick win: Take one of your regular Excel reports and try to turn the key numbers into a simple chart in Excel or Power BI. It's a small step, but a good start.

Basic Total Cost of Ownership (TCO) Analysis

We're moving beyond just looking at the purchase price. Understanding the full cost of an item (shipping, installation, maintenance, disposal) helps us make smarter buying decisions, and you'll need to contribute to this.

Direct vs. Indirect Costs · Lifecycle Costing · Quantifying Hidden Costs

  • This month: Read up on basic TCO principles, perhaps an article or two from a procurement journal.
  • Month 2: Pick one routine item you buy and try to map out all the costs associated with it, beyond just the purchase price.
  • Month 3: Discuss your TCO findings with your manager or a senior colleague to get their perspective.
  • Month 4: Start incorporating basic TCO thinking into your supplier comparisons, even if it's just a simple spreadsheet.

Quick win: For your next office supplies order, try to calculate the cost of delivery, not just the items themselves. It's a small start to TCO thinking.

11Staying current once you are in

What people here do to keep up
  • Attending industry webinars or online courses on topics like 'Effective Supplier Communication' or 'P2P Process Optimisation'.
  • Joining relevant LinkedIn groups or online communities to learn from other procurement professionals.
  • Taking advantage of any internal training programmes we offer on our ERP system or other procurement tools.
  • Seeking out mentorship from more senior colleagues within the Procurement team.

Where it leads

The career path, and where it branches

Buying Assistant is a start, not a ceiling. Each step below asks for new skills and hands back more autonomy.

  1. Senior Buying Assistant / Junior Buyer

    2-3 years in the Buying Assistant role

    You'll move from independently managing routine tasks to taking on slightly more complex categories or workstreams, with less direct supervision.

Working with AI on the job

Working with AI

Where AI is starting to help

Imagine getting through your administrative tasks in a fraction of the time, freeing you up to actually solve problems and build better supplier relationships. That's the reality with AI in Procurement, and we're building a hub to help you get there.

For a Buying Assistant, AI isn't about replacing your job; it's about taking the grunt work off your plate. Think less time chasing invoices and more time ensuring we get the best value. Here's how AI will change your day-to-day:

Automated Invoice Matching

AI tools will automatically perform the '3-way match' between Purchase Orders, goods receipts, and invoices. It'll flag only the true exceptions for your review, meaning you spend less time manually checking and more time fixing the real issues.

Intelligent Supplier Discovery

Need a new supplier for custom packaging in the Midlands with specific certifications? Use an AI-powered prompt like, 'Find three alternative suppliers for custom corrugated boxes in the North of England with ISO 9001 certification and positive ESG ratings.' It'll drastically cut down your research time for RFQs.

Proactive Delivery Tracking & Comms

AI can monitor carrier data and automatically draft follow-up emails to suppliers for orders that are predicted to be late. It'll also notify internal stakeholders, meaning you're always ahead of the curve and not constantly chasing updates yourself.

Automated Documentation & Summaries

Ever finish a supplier call and dread writing up the notes? AI can transcribe and summarise your meetings, pulling out key actions and agreements. It can also help draft standard email responses or internal updates, saving you a good chunk of time.
