Invoice Koi

Invoicing for irrigation and sprinkler contractors

An irrigation system is sold once and serviced forever. The install is a proper job with zones, valves and trenching to price; everything after it is small: a head that has been mown off, a valve that sticks, and the two visits a year that shut it down and wake it up again. The small work is where the money leaks, because it is not worth writing an invoice for and it never gets one.

What irrigation and sprinkler contractors
put on an invoice.

These go in your price book once, with your own prices against them. After that a line is one tap: the item, the description, the unit and the price fill themselves, and the totals resolve underneath.

Prices are yours. Invoice Koi ships a handful of round placeholder lines to start from and never fills your book with figures you did not set.

02Why irrigation and sprinkler contractors use it

Three things that
save the evening.

Two visits a year, invoiced without being chased

The fall blow-out and the spring start-up are a recurring invoice on a yearly cadence. The draft appears when it is due, and small seasonal work stops being work you did for nothing.

Heads, valves and controllers already priced

The parts you install every week sit in the price book with their own units. A repair visit is three taps and a total rather than a job you write up later and round down.

An install a customer can follow

Group the design, the zones and the controls with their own subtotals, so a four figure system reads as a set of decisions instead of a single number.

03 · Questions

Asked by irrigation and sprinkler contractors.

Can I set up an annual winterizing visit that invoices itself?

Yes. Set a recurring invoice on a yearly cadence and the draft is waiting on the date you chose, with the client and the line already on it.

How do I bill a repair that took twenty minutes?

A minimum charge or a service call line from the price book covers it, and it is written on the phone before you leave rather than remembered that evening.

Can I quote a system zone by zone?

Yes. Each zone is its own group with its own subtotal, so a customer can start with the lawn and add the beds next spring.
