Hire on one answer: will they model your exemption conditions as rules the system enforces, or as a document you upload. The second is a filing cabinet with a login. A first release joining the flight record, the pesticide record and the invoice runs $35,000 to $85,000 over 8 to 12 weeks. Buy discovery before you commit to a build.
Sunday evening, and somebody in your office is rebuilding a week. Twenty three fields across two counties, two aircraft, a camera roll of handwritten mix sheets, a controller log, and three texts with acreage in them. Out of that come three documents that have to agree: a dispensing record for the operating certificate side, a pesticide application record for the state lead agency, and an invoice at a per acre rate. They will not agree. The acreage on the invoice comes from the grower's field boundary, the acreage in the pesticide record comes from what the pilot thought was treated, and the four percent gap between them never gets investigated.
Buying software for this is hard because nothing on the market covers the middle. The software shipped with the aircraft stops at the airframe: it plans a mission, flies it, logs telemetry and draws an as-flown map, and it has no concept of a grower, a work order, a product registration number, a certified applicator or an invoice. Agronomy and application software goes the other way, modelling fields, products and records competently while assuming a ground rig with a boom and a rate controller. Neither has a place to put a remote pilot certificate number, a visual observer, an aircraft serial or three aircraft on one field.
What a spray drone software company actually does
The demo is a job list and a map. The substance is one job object per field pass that carries all three record sets and the billing line at once, captured in the field and never retyped: aircraft, remote pilot, applicator certification, product and registration number, rate, mix, acres planned and acres actually treated, start and end times, weather, buffers, restricted entry interval and the invoice terms.
Around that object sit the parts that decide whether the system survives a season. Offline first capture, because you will work fields with no signal and you will not stop flying for a bar, with sync that resolves conflicts rather than duplicating jobs when two devices come back online. A parser per aircraft platform, because mixed fleets are normal and log formats are not standardised. Your exemption and certificate conditions expressed as rules the scheduler enforces, covering aircraft weight limits, how many aircraft one remote pilot may supervise, observer requirements and operating hours, because the crew in the field has not reread the grant document this month.
Then the register that catches people out: two separate credential clocks, one for remote pilot currency and one for applicator certification, with expiry alerts and hard blocks. Mix and chemical inventory drawn per job, distinguishing chemical you supplied from chemical the grower supplied, since that changes both the invoice and who owns the record. Acreage reconciliation between planned boundary, as-flown coverage and billed acres, with the variance visible. And an append only trail, because silent corrections destroy the evidentiary value of everything above them.
What it really costs in 2026
Digital Heroes delivery bands for commercial application operators.
| Project tier | Cost | Timeline |
|---|---|---|
| Field capture and joined record only, invoicing exported to your accountant | $18,000 to $38,000 | 5 to 8 weeks |
| First release: capture, flight and pesticide records, per acre invoicing | $35,000 to $85,000 | 8 to 12 weeks |
| Full platform: multi crew dispatch, mix inventory, maintenance, multi state formats, grower portal | $95,000 to $220,000 | 4 to 8 months |
| Support, new log formats and new state record definitions | 15 to 20 percent of build per year | Retainer |
Two costs sit outside almost every quote.
The first is log parsing as maintenance rather than build. Aircraft manufacturers change their log formats, sometimes mid season, and the parser you paid for in February is the parser that stops working in July. Ask for it to be quoted as a mapping layer you control plus an ongoing allowance, not as a one time integration line that quietly becomes your problem.
The second is each additional state you fly into. Every state lead agency defines its application record and its retention period differently, so a second state is a mapping, a validation set and a report format, not a checkbox. Operators who expand across a state line in year two routinely discover this after the software was scoped for one.
Signals of a strong partner
- They ask which exemption and conditions you fly under. Your grant is not the same as the operator down the road, and the rules belong in the system.
- They raise offline conflict resolution unprompted. Two crews, two devices, no signal, overlapping edits to the same grower job.
- They separate grower supplied chemical from yours. It changes the invoice and it changes whose record it is.
- They price parsers per aircraft platform. A single integration line covering a mixed fleet has priced one manufacturer.
- They ask what happens when acreage disagrees. The reconciliation report is what ends billing disputes before they start.
- They treat corrections as append only entries. Attributed and visible, never silent edits over the original.
- They put the repository and cloud accounts in your name. In a category with no packaged fallback, lockout ends your record keeping.
Red flags
- Your exemption uploaded as a PDF attachment. A document store does not stop a crew doing something on a hot afternoon that costs you the authority to fly.
- A cloud only mobile app. Half your fields have no signal, and a capture flow that needs a connection will not be used.
- One credential field on the pilot record. Remote pilot currency and applicator certification are two clocks with two renewal paths.
- Dispatch and scheduling built first. Most operations overbuild scheduling long before they have three crews to schedule.
- No question about restricted entry intervals or buffers. Those belong on the record and on the grower notification, and their absence signals nobody has read a state record definition.
Questions to ask on the first call
- How will you turn our exemption conditions into rules that block a job from being scheduled?
- Two crews, two phones, no signal, both editing the same grower job. What happens at sync?
- Which aircraft manufacturers' flight logs have you parsed, and what did you do when a format changed?
- How do planned boundary acres, as-flown coverage and billed acres get reconciled on one screen?
- Where do the product registration number, rate, target pest and restricted entry interval live on the record?
- How does the system track remote pilot currency and applicator certification as separate expiry clocks?
- If we add a second state next season, what work is that and what does it cost?
- How is battery set and airframe service life tracked by cycles and hours?
- Who owns the repository, the cloud accounts and every record in the system on day one?
A simple way to decide
Pay for a short discovery phase rather than choosing from proposals. What you should hold at the end is a written specification: the single job object with every field the two record sets require, your exemption conditions as enforceable rules, the log parsing approach per manufacturer, the state record mappings you need now and next season, the billing model with minimums and mobilisation, and a phased plan that leaves dispatch until you genuinely have three crews. That specification is yours, and any firm can quote against it.
Digital Heroes is the wrong choice if you fly one aircraft solo across a few thousand acres a season. Your record keeping problem is discipline, and a well designed spreadsheet plus a photo folder genuinely works at that size. The same applies if drone application is a sideline to a ground rig business, because your records belong wherever your ground application records already live. We fit at three or more aircraft, more than one crew, or more than one state. Digital Heroes runs PRD-first delivery, has delivered 2,000+ projects, and contracts through an India LLP, a US LLC or a UK LTD so the code assigns under your own law.

Frequently asked questions
How much does custom spray drone software cost?
Field capture with the joined flight and pesticide record, exporting to your accountant for billing, runs $18,000 to $38,000. A first release adding per acre invoicing runs $35,000 to $85,000 over 8 to 12 weeks. A full platform with multi crew dispatch, mix and chemical inventory, aircraft and battery maintenance, multi state formats and a grower portal runs $95,000 to $220,000.
Why is there no off the shelf product for this?
Because the two adjacent categories stop short from opposite directions. Aircraft software ends at the airframe and knows nothing about growers, applicators, registration numbers or invoices. Agronomy software models fields and products well but assumes a ground rig with a boom. Add operating rules that vary per exemption grant and no product vendor can encode them, so they encode none and leave the operator remembering.
Can the software enforce our exemption conditions?
It should, and that is the question that separates a real build from a document store. Aircraft weight limits, aircraft per remote pilot, observer requirements and operating hours belong in the scheduler as rules that refuse a non compliant job. Ask a vendor directly whether conditions become enforceable logic or an uploaded file. The second answer means your crew is still the only safeguard.
What does it cost to add a second state?
More than most quotes assume. Each state lead agency defines its application record fields and its retention period differently, so a second state is a field mapping, a validation rule set and a report format. Scope it at the start if expansion is likely, because retrofitting a second record definition into a system designed around one is consistently more expensive than building for two.
Do we own the code and the records?
You should own the repository, the cloud accounts and every record from the first commit, in writing before kickoff. This matters more here than in most categories because there is no packaged product to fall back on. Being locked out of your own system is not an inconvenience, it is the end of your record keeping, and your records are what keep your authority to operate intact.
What are the biggest mistakes first-time software buyers make?
Choosing the lowest bid, paying more than 30-40% upfront instead of on milestones, skipping a written specification, and having no maintenance plan for after launch. The most expensive of the four in Digital Heroes rescue projects is the missing spec: without written acceptance criteria, done becomes an argument instead of a checklist, and every disagreement resolves in the vendor's favor. Fix those four and you have avoided most of the ways these projects fail.
What security does my app need if it takes payments?
Never store card numbers yourself: run payments through Stripe, Braintree, or a similar processor's software development kit so the heaviest compliance burden stays with the processor. Beyond that, a properly built app encrypts all traffic, keeps session tokens in the platform's secure storage (iOS Keychain, Android Keystore), and enforces backend rules so one user can never read another's records. Ask a prospective agency how they handle those three things; vague answers are disqualifying.
How long does it take to build a custom web or mobile app from scratch?
Plan on 8 to 16 weeks for a focused first version and 4 to 9 months for a larger platform, which is the typical spread across Digital Heroes builds. The first 2 to 3 weeks go to discovery and design before any production code ships. The two things that stretch timelines most are integrations with legacy systems and slow feedback from your side, not developer speed.
Who owns the code when an agency builds my software?
You should, completely, through a written intellectual property assignment that transfers everything on final payment; without that clause, copyright stays with whoever wrote the code by default. Insist that the repository lives in your own GitHub organization from day one and that hosting, domains, and third-party accounts are registered to you. Also check for licenses to the agency's proprietary frameworks buried in the contract, because those can make switching vendors practically impossible even when you own your own code.
Should I hire a freelancer or an agency to build my app?
A strong freelancer suits a small, tightly defined app where you supply the product direction and design references yourself; in the competing quotes Digital Heroes sees, freelance rates usually run $30 to $100 an hour. An agency earns its overhead when you need design, mobile, backend, and testing in one accountable team, and when the project cannot stall because one person disappears. A rough dividing line is $25,000 of scope: below it, a good freelancer is often the better buy.
Should I launch with an MVP or wait until the app feels complete?
Launch the minimum viable product, because no app is ever complete and real store reviews reshape a roadmap faster than any internal debate. In Digital Heroes delivery experience, a focused first release with five to eight core features runs 40 to 60% less than the founder's full wish list and ships months sooner. The discipline is choosing the one job the app must do perfectly and deferring everything else to updates.
How much should a small business budget for its first custom app or website?
For a focused first build, most small businesses land between $8,000 and $60,000: roughly $8,000 to $45,000 for a custom website and $25,000 to $60,000 for an internal tool or simple web app, based on Digital Heroes delivery across 2,000+ projects. Customer-facing products with payments, logins, or a mobile app start around $40,000. Quotes far below these bands usually mean a template with your logo on it, not software shaped around your workflow.
Is custom software more secure than off-the-shelf SaaS?
Neither is secure by default; security tracks the practices of whoever builds and operates the system, not the model. SaaS gives you the vendor's certifications and patching but puts your data in a shared multi-tenant platform on their terms, while custom gives you full control over data residency, access rules, and compliance requirements like HIPAA, with the responsibility sitting with you and your agency. Before hiring anyone for a system holding sensitive data, ask for their security checklist: encryption at rest and in transit, an OWASP Top 10 review, role-based access, and a penetration test before launch.
Should I sign a fixed-price contract or pay time and materials for my app?
Fixed price fits a tightly scoped version one with a frozen feature list; time and materials fits ongoing product work where priorities shift monthly. The catch with fixed price is that every change becomes a negotiation, and the quote carries a built-in risk premium. A common middle path is fixed-price discovery and design, then time and materials with a monthly cap for the build.
What does it cost to keep custom software running after launch?
Budget 15-20% of the original build cost per year, which on a $100,000 system means $15,000 to $20,000 for security patches, dependency updates, bug fixes, and small improvements as real usage reveals what the spec missed. Cloud hosting for a typical business application adds $50 to $300 a month on top. Skipping maintenance does not save the money; in Digital Heroes rescue work, unmaintained systems typically need a far more expensive rebuild within about three years.
Who owns the source code when an agency builds my app?
You should own the source code outright, and the contract must say it plainly with an intellectual property assignment that transfers ownership on final payment. Watch for agreements that only license the code to you, keep it in the agency's repository, or register the Apple and Google developer accounts under the agency's name. Insist on code delivered into a repository you control from week one, not at final handover.
Who can build a custom mobile app system?
Digital Heroes builds custom mobile app systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other mobile app companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
