Every business needs to buy things. Raw materials, components, packaging, equipment, services. The list is long and it never stops.
But before any of that gets ordered, most businesses require someone to approve the purchase. That approval step exists for good reason. It controls spending, prevents unauthorised orders, and keeps your finance team in control of committed costs.
The problem is that in a lot of UK businesses, that approval step is slow. Sometimes very slow.
A purchase request sits in someone’s inbox for three days. The approver is travelling. The request gets forwarded to the wrong person. Nobody is quite sure who needs to sign off on orders above a certain value. The supplier chases you. Production is waiting on a component that hasn’t been ordered yet because the purchase order is stuck waiting for a signature.
This is not a people problem. It is a process problem. And it is one that Business Central is built to solve.
Why Purchase Order Approval Slows Down
Most approval bottlenecks come from one of three places.
The process is informal. Approvals happen by email, Teams message, or someone walking over to a manager’s desk. There is no clear route, no escalation path, and no way to see where a request is at any time.
The rules are unclear. Who approves a £500 order? What about £5,000? Does it matter which category the spend falls into? If your team doesn’t know the rules, they either guess or ask someone, which takes time either way.
There is no audit trail. When finance or management asks who approved a purchase, the answer involves trawling through email threads. That is nobody’s idea of a good Friday afternoon.
Each of these problems is fixable. Business Central gives you the tools to fix all three at once.
How Business Central Handles Purchase Order Approvals
Business Central includes a workflow engine that lets you build structured approval processes for purchase orders. You define the rules once. The system applies them every time.
Here is how it works in practice.
Approval Workflows
You set up approval workflows based on the criteria that matter to your business. That might be order value, the supplier, the item category, or the department placing the order.
When a purchase order is created and meets the criteria, it is automatically routed to the right approver. The approver gets a notification. They review the order in Business Central and either approve or reject it. If they reject it, they can add a reason. The requester is notified either way.
No emails. No chasing. No ambiguity about where the order is in the process.
Authorisation Limits
You can set authorisation limits for each user. A junior buyer might be able to approve orders up to £1,000. A department manager up to £10,000. Anything above that goes to finance or a director.
If an approver tries to approve an order above their limit, Business Central escalates it automatically to the next level. You do not need to rely on people knowing the rules and following them. The system enforces them.
Delegation and Absence Cover
One of the most common causes of approval delays is a single point of failure. One approver. One inbox. One person on annual leave.
Business Central lets you set up delegation rules. If an approver is unavailable, requests route to a nominated delegate automatically. Your purchasing process keeps moving even when key people are out of the office.
Approval History and Audit Trail
Every approval decision is recorded in Business Central. Who approved it. When they approved it. What the order value was. Whether it was escalated and why.
That audit trail is available instantly. When your finance team needs to review committed spend, when an auditor asks for evidence of purchasing controls, or when management wants to understand a particular purchase decision, the information is already there.
Three-Way Matching
Approval before the order goes out is one control. Matching what arrives against what you ordered and what you were invoiced is another.
Business Central supports three-way matching between the purchase order, the goods receipt, and the supplier invoice. Before a supplier invoice is approved for payment, the system checks that the quantity and price match what was ordered and what was received.
If there is a discrepancy, the invoice is flagged for review rather than passed straight to payment. This catches billing errors, quantity disputes, and duplicate invoices before they become a problem for your accounts payable team.
For businesses processing a high volume of supplier invoices, three-way matching removes a significant amount of manual checking and reduces the risk of paying for something you did not receive.
Visibility Across the Purchasing Process
Beyond individual approvals, Business Central gives management a clear view of purchasing activity across the business.
You can see all open purchase orders, their approval status, and their expected delivery dates. You can track committed spend against budget. You can identify which suppliers have outstanding orders and which have been approved for payment.
For finance teams managing cash flow, that visibility matters. You are not waiting for someone to update a spreadsheet. The data is live in the system.
For operations teams managing production schedules or stock replenishment, knowing the status of an outstanding purchase order without having to chase the purchasing team is a practical improvement to how the business runs day to day.
Who This Is For
If your business processes more than a handful of purchase orders a week and relies on email or informal sign-off for approvals, you are carrying unnecessary risk and unnecessary delay.
This is particularly relevant for:
- Manufacturers where production depends on components arriving on time and purchase delays have a direct operational cost
- Distributors and wholesalers managing high volumes of supplier orders where errors and delays affect customer service
- Food and beverage businesses where purchasing controls are part of supplier management and compliance requirements
- Any UK business that has grown beyond the point where informal purchasing processes are good enough
Business Central gives you a purchasing process that is controlled, auditable, and fast enough to keep your business moving.
FAQs
For anything not covered here, get in touch directly. We’re happy to answer questions specific to your business and your ERP requirements.
You define the approval rules in Business Central based on order value, supplier, category, or department. When a purchase order meets the criteria, it routes automatically to the right approver. The approver is notified, reviews the order, and approves or rejects it in the system.
Yes. You assign authorisation limits to each user. Orders above a user’s limit escalate automatically to the next level of approval. The system enforces the limits without relying on users to know and follow the rules.
You can set up delegation rules so that if an approver is absent, requests route to a nominated delegate automatically. This prevents approval queues from building up when key people are out of the office.
Three-way matching compares the purchase order, the goods receipt, and the supplier invoice. If the quantities or prices do not match, the invoice is flagged for review before it is approved for payment. This reduces errors and prevents payment for goods not received.
Yes. Every approval decision is recorded in Business Central, including who approved it, when, and at what value. This gives your finance team and auditors a complete, searchable audit trail without trawling through email.
