What would it cost to build your own field ticketing app?
Building it takes a weekend. Running it takes years. Here's the full bill.

How long you expect to run the app.
Year one carries every build hour, and the monthly costs keep running after it. A billing system usually runs for years, so try the 3- and 5-year views too.

These are planning estimates, not quotes. The labor lines already count your team's time, so don't add those hours again elsewhere.
With our default estimates, building and running your own field ticketing app with AI costs about $15,220 to $49,680 over three years, plus 208 to 518 hours of your builder's time. That's before a billing error reaches a customer, the builder leaves, or a security incident happens.
What the total doesn't include
The receipt prices routine work. These costs don't arrive on a schedule.
Billing bugs
A shift past midnight bills on the wrong day. A rate change reprices last month's tickets. One ticket gets invoiced twice.
The person who built the app leaves
You're left with code nobody else understands.
A security incident or data loss
Client rates and employee records are your liability.
Features you deferred
Timesheets and payroll hand-off, full offline mode and compliance tracking. Each one is another build.
Aimsio has spent 11+ years working through these problems firsthand, across 6.5M+ tickets and $13B+ in invoices. A weekend build meets them for the first time.
Read the full breakdown →Build vs. buy: what you're signing up for
Software is the part you can see. The service is everything that keeps it working while you run your business. Here's who carries each piece.
| Area | When you build | When you buy |
|---|---|---|
| Security | You handle logins, password resets, permissions on every page and endpoint, and patching the libraries your app depends on. | Aimsio runs on Amazon Web Services. Staff access to your data is restricted and monitored. Database access requires an approved IP address, a private key and two-step verification, over an encrypted connection. |
| Backups | You choose, pay for and test your backups. On Supabase, for example, the free plan has no automatic backups, and restoring to a specific minute is an add-on starting at $1,200 a year. | Customer data is backed up every hour, and backups are kept for up to 7 days. |
| Maintenance | You apply framework and package updates. Skip a year and the upgrade becomes a rewrite. | Aimsio maintains and updates the platform. |
| Support | When a foreman can't log in at 6 a.m., someone on your team answers. | Aimsio's support team is available Monday to Friday, 9 a.m. to 5 p.m. Mountain Time, through the success portal or by email. |
| Accounting system changes | When your accounting system changes its API, you update the integration. | Aimsio's professional services team maintains our accounting integrations and monitors changes with integration partners to keep them current. |
| Key-person risk | If the builder leaves, the app's knowledge leaves with them. | The platform doesn't depend on one person at your company. |
Before you decide
Answer these with whoever would own the app. They're the questions that separate a weekend demo from a system you can bill from.
- Who owns this in year three, and who covers when they're away or gone?
- Who reviews every change that touches rates, tax or invoices?
- Where are the automated tests, and who keeps them passing?
- When did we last restore a backup, and how long did it take?
- What happens to our billing if the app is down on invoice day?
- Which features from our original wish list does it still not do?
- Have we priced the builder's time, not just the tool subscriptions?
- Would we be comfortable showing this system to a customer's auditor?
If you can answer all eight with confidence, building may be the right call. If a few gave you pause, that's the work you'd be handing to us.
These questions come from Yes, You Can Vibe-Code Your Own Field Ticketing Software, where Abbas Sarraf walks through each one.
When building makes sense
Building can be the right call. When you're weighing custom software against off-the-shelf, building fits when you have:
- A developer, or a very technical employee, who wants to own it for years
- A simple, stable process that rarely changes
- No compliance, integration or audit pressure
It's also a good way to learn what you actually need. Some of our best conversations started with a prototype someone built, because it forced them to write down their requirements.
Run Aimsio next to your build.
Start a 30-day free trial of Aimsio Lite and put the same tickets and Price Books through both for the same month. You'll see quickly where each one holds up.

Frequently asked questions
How accurate is the calculator?
It's a planning estimate, not a quote. The defaults come from the three-year estimate in our build-vs-buy post, with a best case and a realistic case. Your builder's hourly cost and monthly maintenance hours move the total the most, so start there.
What costs does it leave out?
Anything that doesn't happen on a schedule: a billing bug that reaches a customer, an extended outage, a customer dispute, a security incident, or a handover if the builder leaves. It also leaves out onboarding, data migration and training, which apply whether you build or buy.
What should I check before comparing a build to a software subscription?
Make sure you're comparing the same thing. A subscription usually includes support, backups, security updates and integration upkeep, and many plans include dispatch, payroll hand-off and accounting integrations. Each of those is extra build and upkeep on your side. Then weigh the costs the receipt can't price.
Is custom software or off-the-shelf software better for field ticketing?
It depends on who will own it. Custom software fits when you have a developer who wants to maintain it for years, a simple and stable process, and no compliance or integration pressure. Off-the-shelf software fits when billing accuracy, support and integrations matter more than owning the code. The calculator shows the cost side, and the checklist above covers the rest.
Who should own a custom-built system long term?
One named person with a backup. They review every change that touches rates, tax or invoices, keep the automated tests passing, and test that backups restore. If nobody can say who that is in year three, treat it as a risk.
Can I build something first and switch later?
Yes, and a prototype is a good way to pin down what you need. Plan for the move, though: your jobs, rates and ticket history have to come with you, and moving off some build platforms is a project of its own. Running a free trial alongside your build lets you compare before you commit.
How much does it cost to build vs. buy?
With the calculator's realistic defaults, a self-built app runs about $49,680 over three years, plus 518 hours of your builder's time. The best case is about $15,220. Neither number includes the costs that hurt most: a billing bug that reaches a customer, the builder leaving, or a security incident.
