Spray records that are complete before the rig leaves the paddock
For a spraying contractor, the job isn't finished until the record is: product, rate, paddock, conditions and who applied it. Too often that's a clipboard in the cab and a late night typing it up. Below, a fictional Horsham contractor books jobs, checks conditions before starting, and signs the record in the cab.
In short
A spray records app for agricultural contractors books jobs with product, rate and area, checks weather conditions such as delta T and wind speed before spraying starts, and captures a complete application record in the cab. The operator signs it, and the invoice and a clean record go to the farmer.

What you just used
Every screen is a decision about how the work runs
Jobs booked with the numbers done
Paddocks, hectares, product and rate go in once, and total product, water, tank loads and price are calculated. The operator heads out with a plan, not a phone call.
A conditions gate before spraying
Wind speed and direction, temperature, humidity and delta T are shown as gauges, with inversion risk flagged. Out of range means the job can't start, which is exactly when a clipboard gets skipped.
The record captured as the work happens
Product, rate, water rate, nozzle and pressure, paddock, times and conditions at intervals, recorded in the cab. Nothing depends on remembering it that night.
Sensitive areas noted
Neighbouring crops, vineyards, waterways and houses are marked on the job, with a downwind check before starting. The things that cause disputes are recorded before they happen.
Signed by the operator
The operator signs the completed record, which is stored with the job and the conditions. When a question comes up months later, the record answers it.
Invoice and record to the farmer together
Hectares, rates and product become the invoice, and the farmer receives a clean copy of the spray record for their own records at the same time.
Built for you
Your rules, not a template's
Built for your business, it would follow your rigs, jobs and records:
- Your rigs, tank sizes, nozzles and rates
- Your clients, farms and paddock maps
- Live weather from your own station or a weather service
- Record fields matched to your licence and your clients' requirements
- Invoicing into Xero with your pricing
- Harvest and other contract work alongside spraying
Connects to what you already use
Where a tool offers an API or a calendar feed, the build talks to it directly. Your data stays in accounts you own.
- Xero
- MYOB
- Weather stations
- Weather services
- Paddock maps
- SMS
Custom app, a farm platform's spray diary, or paper?
Farm management platforms include spray diaries, and many farmers use them for their own spraying. A contractor's needs differ: many clients, many farms, and records that go back to each farmer.
| Criteria | Paper spray diary | Farm platform spray diary | Custom contractor app |
|---|---|---|---|
| Many clients and farms | A folder each | Built for one farm | Built for many |
| Conditions gate | Operator's judgement | Varies | Built in, with your thresholds |
| Records to the farmer | Photocopies | Shared if they use the platform | Sent with the invoice |
| Invoicing | Typed up later | Separate | From the job |
| Ongoing cost | Your evenings | Subscription | Hosting and support |
| Best when | A small number of jobs for a few farms | You mainly spray your own farm | A contracting business with many clients and rigs |
How we'd build yours
Fixed price, agreed before we start
Ride along for a day
From the booking call to the invoice, we see how jobs, records and conditions are handled, and where they slip.
Fix the scope and the price
Jobs, conditions, records, invoices and integrations in the first version, with one fixed price you approve before we start.
Test it in the cab
The in-cab screens are tested on a real rig, with poor signal and bright sun, until they're quick to use one-handed.
Run a season with it
A season of jobs builds the history, and we tidy the records and invoices based on what clients ask for.
What moves the price
Custom work is quoted individually, at a fixed price, once the scope is written down. These are the things that make the biggest difference.
- Weather data
- A weather service is simpler than connecting your own station.
- Offline use
- Cab screens that work without signal need offline storage and sync.
- Invoicing
- Xero or MYOB integration adds a connection.
- Other contract work
- Harvest, seeding and cartage each add job types.
When you shouldn't build this
If you do a handful of jobs for a few neighbours, a good paper spray diary and a carbon copy is enough. If you mainly spray your own farm, your farm platform's spray diary will serve you better. A custom app makes sense for contracting businesses with many clients, several rigs and records that need to go back to each farmer.

Common questions
Typically the product and its rate, the water rate, the paddock and area treated, the date and times, the weather conditions, the equipment used and the person who applied it. Requirements depend on the chemical and your licence, so check with Agriculture Victoria.
Delta T is a measure of evaporation that combines temperature and humidity. Between about 2 and 8 is generally considered suitable for spraying; above 10, droplets evaporate too quickly and spraying should usually stop. The product label always takes priority.
Too much wind carries spray off target, and too little can mean a temperature inversion, where fine droplets hang and drift. Labels often specify a wind range, and records should note speed and direction at the time of spraying.
Yes, if it's built to. Records are saved on the device in the cab and synced when signal returns, which matters across much of the Wimmera and Mallee.
They should. A contractor's app can send each client a clean copy of the record with the invoice, which helps the farmer meet their own record-keeping and quality assurance requirements.
