What goes on a plumber's purchase order to merchants?
A plumber sends a purchase order to trade merchants to authorise pipe, fittings, and fixtures before collection or delivery. List each item with the size or spec, the quantity, and the agreed trade price, plus the job it is for. The PO gives the merchant an approved order, and the invoice that follows references its number.
Typical line items
- Pipe by material and diameter
- Fittings and valves (assortment)
- Fixtures (basins, taps, cisterns)
- Sealants and consumables
- Job or site reference
- Quantity per line
- Agreed trade price per unit
- Collection or delivery date
How the work is charged
Plumbing materials are priced per length, per fitting, or per unit at agreed trade rates. The purchase order records the figures so the merchant's invoice can be checked against approved costs.
Payment terms and deposits
Merchant accounts commonly run net 30 from end of month. The order authorises spend up to its total, and the supplier should quote the PO number so deliveries reconcile against the right job.
Tax and compliance
If sales tax or VAT applies, list it separately with the registration number. Some plumbing work and materials carry distinct rates in places, so confirm what applies to the order.
Frequently asked questions
Do plumbers need purchase orders for small jobs?
For very small purchases, informal ordering is common. However, for larger fixture or materials orders above a few hundred euros, a PO protects you if there are delivery or pricing disputes.
What details should a plumber's PO include?
Include product names, pipe sizes and grades, quantities, agreed trade prices, and (if applicable) the job or customer reference so you can charge materials back correctly.
How do I return faulty plumbing materials?
Quote your original PO number when arranging a return. Suppliers will cross-reference the PO against the delivery to confirm the goods were supplied by them and process a credit.
