Systems integration · QuickBooks · Custom software · Mobile apps
I'm Nathan Clark. I connect the software you already run — QuickBooks, your CRM, the app your crew uses in the field — so a job entered once shows up everywhere it needs to, and nobody keys it in again.
What I build
No retainers. No account manager. No hand-off to a junior. One engineer on the problem costing you the most — me.
When a job finishes in one system, the next system should already know. I connect the software you already run so nobody has to re-type anything — or fix what they re-typed wrong. QuickBooks Desktop and Online, including the Web Connector and the Desktop SDK.
The tool your business actually needs — not the one you're forcing to fit. Customer portals, quoting and scheduling systems, internal dashboards — built around how your business actually works.
Put your business in your customers' pockets — or your crew's. iOS and Android apps for bookings, field work, loyalty, and anything that shouldn't require a clipboard and a phone call.
The repetitive work that eats your week — invoices, follow-ups, quotes, data entry, reports — handled by automations that run around the clock, with AI where it genuinely earns its place. I find where the money is leaking and plug it.
The free call · 30 minutes
Most small businesses are leaking hours — and dollars — into work that two systems talking to each other would do quietly in the background. You don't need an “AI strategy.” You need someone who has connected these systems before to find the three things worth fixing first, and then fix them.
Book the free callBefore
Every completed delivery gets typed into QuickBooks by hand, then the invoice gets updated by hand.
After
The delivery system tells QuickBooks the job is done and the invoice updates itself. (A real client, a real fix.)
Before
Web-form inquiries get copied and pasted into the CRM — when someone remembers.
After
Every inquiry lands in the CRM the second it's submitted, with an instant reply already on its way.
Before
Quotes take two days and a spreadsheet only you understand.
After
Customers get an accurate quote in minutes, from your pricing rules, on their phone.
Before
Someone answers the same twelve questions on the phone all day.
After
An AI assistant handles the routine calls and texts; your people handle the rest.
Before
The month-end report is a copy-paste marathon across four systems.
After
One dashboard, refreshed every morning, with the numbers you actually run on.
Before
Paying for six subscriptions that each do a tenth of what you need.
After
One tool built around your workflow, and the subscriptions you don't need — cancelled.
How the call works
If there's nothing worth fixing, I'll tell you that too. Happens more than you'd think.
Projects start at $1,500, so you'll know early whether this is worth your time.
We walk through a normal week in your business — where the time goes and what feels stuck.
Every repetitive, manual, or error-prone task gets sized: hours per week, cost, and risk.
Before we hang up I tell you the three things worth fixing first, in what order, and roughly what each one takes. Spoken, on the call — no obligation either way.
How I work
A process that's been battle-tested on everything from two-person shops to enterprise platforms serving thousands of users. Simple on purpose.
I learn how your business actually runs — not how the org chart says it does. You'll get a clear scope, a fixed price where it makes sense, and no surprises.
Before a line of code, you see it. Clickable screens and a plain-English plan you can hand to anyone on your team.
Weekly demos of working software. You steer while it's cheap to steer. One engineer start to finish — me. Nobody learning on your dime.
I ship it, train your people, and stick around. Hosting, monitoring, and improvements as your business grows.
The clan behind AppClan
I'm Nathan Clark, and AppClan is me. I've spent more than twenty years building products for agencies, startups and enterprise software companies, and running the DevOps and cloud platforms that keep them online. When you hire AppClan you get that person, on your problem, every time — there is nobody to hand you off to.
That's the part that matters for you: the same rigor that ships software to thousands of users, pointed at the problems that keep a small business up at night. Straight answers, working software, and a phone number I pick up myself.
Let's talk
Tell me what's eating your week. You'll hear back from me — usually the same business day — to set up a free 30-minute call.
