Get Ledger Drone — $59The Problem
If you're an agricultural drone spray pilot, you already know the drill. You finish a job, drive to the next field, and somewhere between takeoff and sunset you need to send a drone spraying invoice. Most pilots handle this one of three ways: scribble it on a notepad and deal with it later, open a spreadsheet on their phone and squint through the glare, or fire up QuickBooks and spend ten minutes configuring line items that don't match what they actually do.
None of these work well. Generic invoicing software wasn't designed for ag drone operations. QuickBooks doesn't know what "acres sprayed" means. It doesn't have fields for chemical applied or rate per acre. Every invoice requires manual configuration — creating custom line items, setting up unit types, and building templates from scratch. That's fine if you're sitting at a desk. It's miserable when you're standing in a muddy field with the sun in your eyes.
Spreadsheets are faster to fill out but create their own problems. They don't generate professional PDFs. You can't attach a photo of the field. Sharing them means emailing a file that the farmer may not be able to open on their phone. And good luck keeping your formulas intact after copying the same template 200 times in a season.
The result is the same: delayed invoices, missed payments, and hours of unpaid office work at the end of each week. For an industry where operators are often solo businesses spraying 500+ acres a day, this isn't just inconvenient — it's lost revenue. A pilot who sprays five fields a day and waits until Friday to invoice has already lost track of half the details.
Drone spraying pilots need invoicing software that speaks their language. Software that knows a job is measured in acres, priced per acre, and tied to a specific field and chemical. Software that works without cell service, because most fields don't have it. Software that gets the invoice done in seconds, not minutes — so you can get back in the air. And if you already use QuickBooks Online for your books, you need those field invoices to flow into your accounting without re-typing everything.
That's why we built Ledger Drone.
Features
Ledger Drone is drone invoicing software designed from day one for agricultural spray operations. Every feature exists because a pilot in the field needed it.
Every invoice comes pre-configured with field name, acres, rate per acre, and chemical applied. No templates to set up. No custom fields to create.
Full offline support as a progressive web app. Create invoices, attach photos, and save PDFs without cell service. Your data stays on your device.
Snap a photo of the field and attach it directly to the invoice. Useful for documentation, proof of completion, or showing the farmer what you sprayed.
Generate a clean, professional PDF with one tap. Share it via text, email, or AirDrop — whatever is fastest for you and the farmer.
Enter acres and rate — the total calculates automatically. No mental math in the field, no formula errors, no second-guessing.
Runs in your browser on iPhone, Android, tablet, or desktop. Add it to your home screen for an app-like experience. No app store required.
How It Works
Creating a professional drone spray invoice takes three steps and about 30 seconds. No templates to configure, no line items to customize, no learning curve.
Open Ledger Drone and tap "New Invoice." Enter the farmer's name, field name, acres sprayed, rate per acre, and chemical applied. The total calculates automatically.
Attach a photo of the field directly from your phone's camera. It embeds in the invoice as proof of completion — great for record-keeping and farmer trust.
Generate a professional PDF and share it instantly via text, email, or AirDrop. The invoice is saved to your device and ready to reference anytime.

Real World
It's 4:30 AM and you're loading the DJI T50 in the dark. By 5:30 AM you're over the first field — 160 acres of corn, applying fungicide at $12 an acre. You land, swap batteries, and pull out your phone. Open Ledger Drone, tap "New Invoice," and type in the field name, acres, rate, and chemical. The total — $1,920 — calculates itself. You snap a photo of the field from the tailgate, hit "Generate PDF," and text it to the farmer. Thirty seconds, done.
By 9:30 you're over the next field. By noon you've sprayed four fields and invoiced all four from the truck between jobs. No laptop, no office, no "I'll do it tonight." The invoices are sent, the farmers have their records, and you haven't lost a single billable minute to paperwork.
End of the week? Your invoices are already done. You don't have a stack of scribbled notes to decode on Sunday night. You don't have to boot up a laptop and spend two hours recreating jobs from memory. Every acre, every field, every chemical — already documented, already sent, already in your records.
That's what invoicing software should be for drone pilots: fast enough to use between fields, simple enough to use with gloves on, and reliable enough to work when you're 20 miles from the nearest cell tower. That's Ledger Drone.
Custom Applicators
Ledger Drone was built for drone spraying pilots, but the workflow fits any custom applicator. If you bill by the acre and track what was applied to which field, this tool works for you — whether you're flying a DJI T50, running a ground rig, or operating a manned aircraft.
Every custom applicator invoice follows the same structure: field name, acres treated, rate per acre, and chemical or product applied. Ledger Drone has these fields built in from the start. There's nothing to configure, no templates to build, and no line items to create. Open the app, fill in the job, and send. The workflow is the same whether you sprayed 40 acres from a drone or 400 acres from a ground sprayer.
If you're a custom applicator looking for a simple, affordable invoice tool that works offline and generates professional PDFs, Ledger Drone is worth a look. One-time purchase, no subscriptions, and built for the field — not the office.
