You’re good at flying. The office side is the problem.

Records everywhere

Jobs on paper, area sprayed in WhatsApp, invoices in another spreadsheet. Something always gets missed.

Prices are falling

New operators undercut to fill their schedule. If you don’t know your true cost, you can’t tell which jobs lose money.

Certificates and batteries

An expired pilot certificate or a tired battery pack shouldn’t be the surprise that grounds you mid-season.

What you get

One job entry feeds everything else

Cost per Hectare calculator

True cost and break-even, so you never quote a losing job.

Job log

Client, field, area, drone and pilot per job, feeding your invoices and summary.

Pilot, aircraft and battery logs

Warnings before certificates expire or servicing is due.

Fuel and consumables

Generator fuel, water and parts tracked against each job.

Records checklist

The records operators commonly keep, plus a prompt to match it to your country’s rules.

Built from an operator’s back office

Made by Paul, finance and admin manager at a certified agricultural drone spraying company, who runs this paperwork every day: costing, job records, fuel, pilots and billing.

Spray Office is the system he wished existed when the season got busy: simple enough to keep up in the field, connected enough to answer “did that job make money?”

Questions

Is this software?

No. It’s a connected spreadsheet kit for Excel or Google Sheets, plus short guides. You own the file, it works offline, and there’s nothing to subscribe to.

Why join a list instead of buying now?

We’re finishing payment setup. Joining holds nothing against you: you’ll get the checkout link by email and decide then.

Will it work in my country?

Yes. You choose your currency and hectares or acres. The records checklist is general, and an included prompt helps you match it to your local aviation and agriculture rules.

I run more than two drones. Is it for me?

It’s built for small teams. With several crews you may outgrow a spreadsheet. Tell us in the form and we’ll be honest about whether it fits.

What if it doesn’t ship?

If it isn’t delivered by 19 October 2026, you get a full refund. See the refund policy.
