Custom software or an app off the shelf? How to decide

When you should just buy an app

We build custom software, and we still tell plenty of owners to buy an app. Field service apps like Jobber, Housecall Pro, or ServiceTitan, property apps like AppFolio, and builder apps like Buildertrend exist because most businesses in a trade schedule, quote, and bill in similar ways. If one fits, you can start this week, the vendor handles updates, and your crew downloads the phone app today.

Our rule of thumb: go with an app when it already does most of what you need, your work runs like everyone else’s in your trade, and a monthly fee per user still feels fair. A landscaper with two crews doing weekly mowing and seasonal cleanups, for example, is usually well served by a field service app and QuickBooks. Paying anyone to rebuild what that app already does is money spent on nothing new.

Signs a custom build is worth a look

Custom starts to make sense when an app costs you in ways that don’t show up on the monthly bill. Look for these:

One sign alone is rarely enough. Two or three together, and it’s worth pricing both paths side by side.

• You pay for several apps that don’t talk to each other, so someone types the same customer, job, or invoice details twice.
• The way you work sets you apart, and the apps make you change it to fit their screens.
• Per-user fees keep climbing as your team grows, including for people who only check their schedule.
• You want your customer and job history in one place that’s yours, not spread across accounts you rent.

How this plays out in your trade

The same questions apply whatever app you’re weighing. Here is how they tend to look in a few trades, as examples.

• HVAC or landscaping, versus a field service app. ServiceTitan describes its pricing as per-technician, and Jobber’s plans each include a set number of users. For a 6-truck HVAC company that runs mostly repair calls, an app often fits. If most of your money comes from maintenance agreements with your own renewal rules, or your dispatcher keeps a spreadsheet next to the app, that gap is what a custom build would close.
• Property management, versus AppFolio. AppFolio’s pricing page lists a minimum spend and, on its Core plan, a 50-unit minimum, with prices by quote. If you manage fewer units than that, or mostly handle maintenance requests for owners, ask what you would actually pay and run the three-year check below.
• Remodeling, versus Buildertrend. Builder apps like Buildertrend are made for the way most remodels run. If your jobs follow that pattern, buy it. If you run design-build with your own selections process, or price from your own cost book, custom may fit better.

How to compare the cost over three years

Monthly fees look small and a build quote looks big, so compare them over the same stretch of time. Three years is a fair window: long enough for monthly fees to add up, short enough to plan for. App: per-user fee × number of people × 36 months, plus add-ons and any other apps you still need beside it. Custom: the one-time build price, plus the monthly hosting and care fee in the quote × 36 months.

Here is a fill-in example. The numbers are made up and rounded to keep the math easy. They are not any vendor’s prices and not a quote from us.

• Example app: $50 per user × 10 people × 36 months = $18,000, plus $100 a month in add-ons × 36 = $3,600. Total: $21,600.
• Example custom build: $14,000 to build, plus the monthly hosting and care in the quote × 36. Add the two and set the total next to the app’s $21,600.

What the totals leave out

Now hire five more people. The app side goes up by $9,000 over three years (5 × $50 × 36). Ask any builder whether their monthly fee changes when you add people, and write both answers down.

Real pricing is rarely one flat rate. Jobber, for example, lists plans that include a set number of users, charges $29 a month for each extra user, and counts anyone who views or manages the team’s schedule as a user (when we checked in October 2026). Use each vendor’s own page or quote.

Then add what the totals leave out. Most apps include updates and support in the fee; check what your plan covers. With custom, changes you want later cost extra, and the build takes weeks. For scale, our typical price for one business system, like scheduling and invoicing for a crew of 5 to 10 connected to QuickBooks, is $6,000–$18,000 over 6–⁠10 weeks. On both sides, count the hours someone spends retyping details between apps today.

Can you keep your apps and build only part?

Yes, and many owners do. They keep Square at the counter or QuickBooks for the books and build only the part no app gets right. A café with catering orders, for example, might keep Square for walk-in sales and add a catering order form and kitchen schedule that connects to Square and QuickBooks Online, so nobody retypes the order.

This keeps the build smaller, and your staff keeps tools they already know. We connect to QuickBooks Online, Square, Stripe, Shopify, Google Calendar, and Gmail or Outlook. For anything else, we check it before we quote.

What you own either way

With an app, you rent. Your customer list and job history live in the vendor’s account, and the fee runs as long as you use it. Before you sign up or switch, ask the vendor how you get all your data out, and in what form.

With a custom build from us, you own the code we write once the project is paid in full; tools from other companies, like QuickBooks or Stripe, keep their own licenses. Hosting runs on our account, and you can take it over after payment. Every launch includes 30 days of fixes. Whoever you hire, ask who owns the code, where it’s hosted, and what happens if you part ways. If those terms matter to your deal, have a lawyer read the contract.

What to write down before you talk to anyone

Before a call with us, an app vendor, or anyone else, spend twenty minutes on this list. It makes every answer easier to compare.

Bring that to any first call. Ours is free, and afterward you get a fixed price in writing within 48 hours, so you can swap our made-up example numbers for real ones. If an app turns out to be the better fit, we’ll say so.

• Every app you pay for, what it costs each month, and how many people use it.
• How many people you expect to have in two to three years.
• Each place someone types the same details twice, and roughly how many hours a week it takes.
• The one part of how you work that the apps make you change.
• What you want to keep, like QuickBooks or Square.
