Custom software and apps

Custom software that fits like it was made for you. Because it was.

Atomic Interactive builds custom software and web tools when a plugin or a subscription doesn't fit: customer and student portals, quote builders, booking systems, product catalogs, internal tools and connections to the software you already use. Every build is quoted line by line before we start.

Custom software we built, live on client sites today.

If it runs online, we can build it. Here are a few of the tools we wrote for clients, and every one is running on a live site today.

Off-the-shelf makes you fit the software. Custom fits you.

  • It fits your process

    Software shaped around how your team already works, so you don't have to change the business to fit a product.

  • It talks to your other tools

    CRMs, payment processors, email platforms and the other systems you rely on. We even speak fluent spreadsheet.

  • One team owns it

    The people who build it also host it and support it. No finger-pointing between vendors.

  • It grows in stages

    Start with the version that solves today's problem. Add to it when the business needs more.

Four steps from idea to working tool.

  1. 1

    Talk it through

    One call about the problem, who uses the tool and what it has to connect to.

  2. 2

    Get a written scope

    A proposal that lists every feature with its hours, so you choose what goes into version one.

  3. 3

    Build and review

    You test each piece on a private preview site and tell us what to change.

  4. 4

    Launch and support

    We train your team, host it, and keep it running and updated.

What people ask before a custom build.

How much does custom software cost?

Every build is quoted in writing after a call. The proposal lists each feature with its hours, so you can start smaller and add later.

Can you add custom features to the website I already have?

Usually, yes. Most of our custom tools are WordPress plugins that add to an existing site. We look at your site first and tell you honestly whether it can handle the job.

Can you connect our website to our CRM or other software?

Yes, as long as the other system offers a way in, such as an API, a webhook or an import file. We have connected sites to CRMs, payment systems and spreadsheets.

What happens after launch?

We host and maintain what we build. Fixes and new features are quoted as you need them or covered under a care plan, whichever fits how often you need changes.

Got a job your software can't do?

Describe what the tool has to do. A real person replies within one business day with questions or a time to talk.
