What goes on an architect's purchase order to suppliers?

An architect issues a purchase order to authorise specialist materials, samples, and project services before a supplier delivers them. List each sample or service, the finish or specification, the agreed price, and the project it belongs to. The PO gives the supplier an approved reference, and any invoice quotes its number.

Typical line items

  • Cladding and finish samples (per set)
  • Specialist glazing or performance reports
  • Model printing service (scale and quantity)
  • Material specification or finish reference
  • Project or job code
  • Agreed price per item or service
  • Required delivery date
  • Delivery address for the studio or site

How the work is charged

Architectural orders mix one-off services priced as a fee with samples or materials priced per unit or per set. The purchase order records each agreed figure so the supplier's invoice can be matched against approved costs.

Payment terms and deposits

State the agreed terms, often net 30 for trade accounts, and tie spend to the value on the order. The PO authorises up to its stated total, so the supplier should reference the PO number on every invoice.

Tax and compliance

Where sales tax or VAT applies, show it as a separate line and include the supplier's registration number. Treatment of professional services and physical samples can differ, so confirm what applies before approving the order.

Frequently asked questions

When do architects issue purchase orders?

Architects issue POs when commissioning specialist consultants (structural engineers, sustainability consultants) or ordering materials for prototyping, sampling, or direct client procurement.

What should an architect's PO include for specialist services?

Include the scope of work, deliverables (drawings, reports, calculations), format and submission requirements, agreed fee, and any RIBA stage references.

How do architects manage procurement for contractor-procured materials?

In a traditional contract, the contractor raises their own POs. Under design-and-build or architect-led procurement, the architect may issue POs directly or via a specialist procurement manager.
