What is an Irrigation Contractor invoice?

An irrigation contractor invoice covers work designing, installing, and maintaining water irrigation systems for gardens, sports grounds, golf courses, commercial landscapes, and agricultural land. Domestic garden irrigation systems typically include pop-up spray heads, drip irrigation for beds, solenoid valve zones, and a controller or smart controller. Commercial systems can be much larger and more complex. Irrigation work involves groundworks (trenching), pipework installation, valve and controller wiring, and commissioning and programming the controller. Annual service contracts covering spring activation, backflow testing, winterisation, and head adjustment are a key revenue source. Smart irrigation controllers and water-saving features increasingly form part of quotes and invoices.

How to invoice as an irrigation contractor

For installation projects, invoice in two stages: deposit (50%) on signing, balance on completion and commissioning. For annual maintenance contracts, invoice annually upfront or at each service visit. Include a system specification list (zones, controller type, head types) with the invoice for the client's property records.
