How to supply goods and services

We need the correct information from you so you can start to supply to us.

Before starting work

Agree on details with your buyer

Confirm what you will supply and the costs with us. Include all costs, like delivery, on the invoice. If the total cost is not included on our purchase order, our system will reject your invoice. This will cause a delay in payment.

Get a purchase order

Wait for a purchase order from us before starting any work. There is a strict No Purchase Order - No Pay policy. This policy makes sure we only pay suppliers for goods or services that have been properly ordered and authorised.

Emergency work

If you need to carry out emergency work, get the details of the person asking for help and make sure they send the purchase order within three days.

Purchase order

A purchase order is our official request for what we want to buy from you. It is the authority to supply and proceed with the service. This authority must be in place before you supply goods or services.

A purchase order can be for a specific number of items (quantity-based) or for services up to a certain amount of money (value-based).

Your purchase order will be sent to the email address you provided. If no email is available, it will be posted according to your supplier account instructions.

If you are a registered supplier with secure credentials, you can update your details through Supplier Self-Service. Otherwise, contact us to request a change of details.

Make sure you have the 10-digit purchase order number and put it on your invoice. It must be typed and not handwritten. The invoice will be returned unpaid if a purchase order number is not stated or handwritten.

Checking the purchase order

Make sure your purchase order is accurate and complete before goods or services are supplied. The invoice must match the purchase order exactly, including all items, quantities, prices and any delivery charges.

If any information is incorrect or requires amending, you should contact the person named on the purchase order (the buyer).

If additional goods or services are required, a new purchase order must be raised.

If there are any changes to prices or charges, these should be agreed with the buyer before invoicing to avoid payment delays.

Make sure you have the 10-digit purchase order number and put it on your invoice. It must be typed and not handwritten.

We use automated systems to match invoices to the corresponding purchase order. If there is not an exact match, manual checks may be required, which can delay payment.
