Real Humans. Ridiculously Useful Tech.
The spreadsheets. The databases that don't talk to each other. The process that lives in one person's head. Most tools cap you, charge more as you grow, then leave you stuck. MosierData builds custom operations software that scales as you do. Built by humans, owned entirely by you, and built to last.
Sound familiar?
The manual process that runs through one person who can't take a vacation. The data spread across three systems that don't talk to each other. The follow-up that slips because nobody's watching. The report someone builds by hand, every single time.
You can describe the symptoms. We name the solution. That's generally how this starts.
Here's what we keep seeing in businesses that call us: they've been making it work long enough that making it work feels normal. It isn't. And on some level, they know it.
The question is usually pretty simple: does your business run the process, or does the process run your business?
What we do
We do two things. One of them is straightforward. One of them is harder to explain. Both are built by humans who understand how your business actually works.
Primary Service
Currently booking Q3 2026Something moves through your business from start to finish: orders, clients, cases, applications, inventory. We build the software that follows it. Web-based, secure, built from scratch by engineers who understand system design, security, and scalability. It scales as you grow, and you own it outright: the software, the source, and your data. No per-seat fees. No ceilings. No lock-in.
Priced per-project, based on scope.
Many projects start under $10,000.
Everything, One Number
2 retainer spots openYou're running a real company while juggling a marketing agency, a web guy, and whoever built your software. None of them talk to each other. When something breaks, they all point at someone else. FSDM replaces that with one number to call. We become the single operator for your whole digital operation. Web, marketing, AI, voice, CRM, email marketing, custom software. We do the work ourselves, or we manage the vendor who does it best. We keep the good ones, and we fire the ones who aren't delivering. Either way, you call us and we handle it. That's the whole idea.
Real impact
Heartland for Children
We built two systems for Heartland: the Rudolph Roundup database that matches foster children's wish lists with donors across three counties, and the OCS/ICPC tracking system that manages out-of-county and interstate placements with automated 30-day compliance notifications. Triple the work. Same staff hours.

We've been Atlas's technology partner since the early 2000s. The booking, manifest, and passenger management systems we built have carried tens of thousands of passengers across multiple fleets. Still running. Still scaling.
Since 2006
We build for longevity. Not every agency builds software meant to last. Most assume you'll be back in three years for a rewrite. We don't. The systems we deliver are owned by you, documented by us, and built to run long after we're done. Our oldest client relationships are 20+ years old.

Most SOP advice hands you a blank template and wishes you luck. The faster way: map the process first, then turn the map into the written procedure. Free template plus a free no-signup tool.
There are a lot of free tools for drawing a process. Far fewer turn that drawing into something you can hand to a new hire or a developer. An honest look at the best free, no-signup options.
Off-the-shelf inventory software fits generic operations. Custom inventory management software fits yours. Here's how to know which is right, and what building it actually costs.
Most websites that aren't generating leads aren't actually broken. The breakdown happens after the form submits, in the follow-up system, the CRM, the response time.
Five phases, 8–24 weeks, fixed price. Here's exactly what happens at each stage, from the first 30-minute call through deployment and handoff.
Most custom software projects for small to mid-size businesses run $8,000 to $75,000 as fixed-price projects. Here's exactly what drives that number up or down.
Who builds your systems matters
Jim started writing software in 1985. Back then, building a business application meant designing the data model, writing every query by hand, and testing it on hardware you built yourself. There were no frameworks. No Stack Overflow. Just the problem and the machine.
That's still how we think about software. Every system we build starts with the same question: what is the actual problem this business needs to solve, and what's the right way to solve it? Not the fashionable way. Not the way that locks you into a vendor. The right way.
The businesses we like working with are ones that take their operations seriously. Where the software isn't decoration, it's infrastructure. If that sounds like you, we should talk.
Most projects start with a free 30-minute call. We'll ask about your operation, tell you what we'd build, and give you a straight answer about whether we're the right fit.
Common questions
We work with small to mid-size businesses that have outgrown their current systems: typically 5 to 200 employees, with a real operational process that needs custom software. We do a lot of work with nonprofits, logistics, field service, and professional services firms.
Off-the-shelf software is designed for the average business. If you're average, it works fine. If your operation has any complexity (unusual workflows, specific data relationships, multiple systems that need to talk), you end up working around the software instead of the other way around. We build software that fits your actual process.
Custom software projects vary widely, but most of our operational tracking and workflow systems start under $10,000 for the initial build. FSDM retainers start from $9,995/month. We give you a scoped estimate before any money changes hands. No surprise overruns.
You do. Completely. You get the source code, the database, and all the documentation. We've had clients run our code for 20+ years without us. That's fine. It's yours.
FSDM makes us the single accountable operator for your entire digital operation: website, software, marketing tech, AI tools, email, CRM, and whatever else you're running. We do the work directly or we manage the vendor who does it best, and we replace any vendor who isn't delivering. Instead of juggling 6 different vendors who don't talk to each other, you have one number to call. If a vendor's involved, we handle it.
