Advisory and software, one operator

Most projects fail in the gap between the advisor and the developer. I'm both. 

I've run service businesses for almost two decades and coded for 28 years. So when your operation is scattered across five apps and three spreadsheets, I can tell you what to change and build it, with nothing lost in translation. Working software in as fast as 7 days.

to a working version

Both sides of the table

Most people know one side. I've worked both.

The operator

I've run the business.

Operations, pricing, hiring, marketing, and the ads. Almost two decades of it, in my own companies. I know how owners actually decide.

The builder

And I build the software.

Twenty-eight years of code. So the tool fits how the business actually works, not the other way around.

Operator and builder in one person, so the advice and the build are never at odds. That is rare, and it is the point.

The core idea

The whole business, connected into one.

Marketing, sales, operations, finance. Today each lives in its own app or spreadsheet, and none of them talk. I see how they actually fit together, then connect them so the same truth shows up everywhere.

Sales
Operations

One source of truth

One action by your team. Everything lands where it should.

Sound familiar?

If any of this sounds like your business, I can help.

1

Spreadsheets and copy-pasting are eating your week

Your team types the same data into three different places every day. Dozens of hours a month go to something the computer should do on its own. You know it's broken. You just haven't had time to fix it.

2

One small mistake costs you real money

Quotes, invoices, contracts. Where a single typo means a fine, a lost client, or a lawyer's bill. Your current method depends on nobody having a bad day. That is not a system. That is luck.

3

The software you pay for annoys you every day

You're tied to a twenty-year-old tool, or a newer one that almost fits but never quite. You pay a lot every month for something your team works around instead of with. There's better. It just doesn't exist yet, shaped to your business.

4

Your customer data lives in five places that don't know about each other

Customers here, appointments there, accounting somewhere else, plus a spreadsheet someone keeps by hand. One simple question means looking in four places. The business runs on what's in one person's head.

5

What you really need didn't exist until recently

A camera that checks work quality on its own. Notes that write themselves from a phone call. Things that were out-of-reach expensive a few years ago, and now take days. If you've been told for years that 'it can't be done,' ask us again.

6

You're about to spend real money and you're not sure it's the right move

A new system, a big software project, a tool everyone's pushing. Once you commit, you're committed. What you actually need is someone who has run a business and can build, to tell you straight whether it's worth it before you spend.

Recognize two or more? Let's talk.

The cost of waiting

How much is all the manual work really costing you?

A rough number in ten seconds. Most owners are surprised how fast it adds up.

You're losing

€74,880*

a year to work the software could do for you.

That's wages spent moving data from one place to another. And it grows every month you wait.

Let's stop that

* An estimate from your inputs. Nothing is stored or sent anywhere.

How it works

From the first call to the problem gone, fast. Here's exactly how.

First I make sure software is even the right move. Often it isn't, and I'll say so. When it is, here's exactly how the build runs, from the first call to live.

  1. Day 0

    The 30-minute call

    We talk. You walk me through your biggest headache, the one that costs the most time or money. I tell you whether the fix is even software, or a change in how the business runs. If it's software and I can do it in a week, we start. If someone else is a better fit, I say so. No pressure, no follow-up spam.

  2. Day 1

    We agree on the details

    If we go ahead, we spend 60 to 90 minutes pinning down exactly what the first week includes, and what it leaves out. I put it on one page, you sign off. The clock starts here.

  3. Days 2-7

    Building

    I build. Every day you get a two-minute video: what's done, what's next, and anything that hit a wall. No pointless meetings, no 'next week.' On day seven, working software runs on your own web address, with your real data in it.

  4. Day 7

    Handover

    Working software, live, with a one-hour walkthrough together. You decide here. Stop with a useful tool in hand, or carry on to the full rollout. Either is fine.

  5. Days 8-30

    Full rollout (if you want it)

    If you continue, I take it from 'it works' to 'the business runs on it.' I connect your existing apps, handle the rarer cases, train your team, make short how-to videos for your staff, and stay with you for a month after launch.

  6. Day 30+

    And after

    Software needs looking after. For an optional monthly fee I maintain it, build new features, or start on the next idea we find together. Or you take the whole thing, docs and all, and run it yourself. Your call.

No PowerPoint. No 'I'll send a proposal next Tuesday.' I build from day one.

* The 7-day and 30-day timelines apply to focused, clearly-scoped software where you provide the needed data, access, and answers without delay. More complex work takes longer, and we agree the exact scope and timeline together before any work starts.

About

I'm Daniel Klinger.

It's a Saturday afternoon. Seven spreadsheets are open on my screen. A customer is on the phone asking about a job we finished last week. Two of my employees need answers I don't have at hand. And somewhere in those seven spreadsheets, the same piece of data is recorded three different ways. I close the laptop, go home, and think: this is no way to run a business. I had been thinking it for years.

I had been writing code since I was ten. I had also spent almost two decades building service businesses, in financial planning, insurance, and high-end auto detailing. The detailing studio I built grew from a small garage into a premium place next door to Ferrari and Maserati, with a team of more than ten and a name most people in the city knew. Through all of it, I kept doing both. The code kept getting better in the background. The businesses kept teaching me how owners actually think.

Sitting on both sides of the table for almost two decades taught me where these projects usually go wrong. The developer and the owner speak two different languages, and nobody in the room speaks both. The developer hears 'I want to keep track of my customers' and builds a customer database. The owner meant something specific, shaped by ten years of running this exact business, and only sees the gap three months and forty thousand euros in. This is the gap I work in.

These days, alongside building software, I help owners with operations and growth. Different trades, different sizes, the same picture every time. Data scattered across five places. Hours a week lost to manual work. A tool nobody likes that still costs a fortune every month. So I started this. I build the software I wish I'd had back then, for owners who are exactly where I was.

A few things you might not expect about me.

  • Before any of this, I had a music career. Platinum and gold records in Switzerland and Austria, and top-charting songs back home.
  • I started at age ten. Twenty-eight years later, I am still doing it.

Track record

A record on both sides of the table.

The software mostly stays invisible: dozens of projects finished under NDA, discretion by default, which for my clients is the point. The business record is real too. Almost two decades running my own service companies, including a detailing studio I built from a garage into a premium name next to Ferrari and Maserati. So the advice is lived, not theoretical.

What I've put right

  • Pricing that left money on the table, rebuilt so the same work earns more.
  • A value proposition nobody quite understood, sharpened into an offer people say yes to.
  • A sales process that leaked deals, tightened so fewer enquiries slip through.
  • Ad spend going to the wrong people, pointed at the ones who actually buy.
  • An operation that only ran when the owner was in the room, turned into a system the team can run.
  • Five apps that never agreed on a customer, connected into one source of truth.

A few things built for clients

A sample, not the full list. There's plenty more.

  • 01Content management system
  • 02Customer database (CRM)
  • 03Quote and proposal generator
  • 04Digital product sales platform
  • 05Client project-delivery portal
  • 06Booking and scheduling system
  • 07Automated invoicing and reconciliation
  • 08Inspection app with photo capture
  • 09Operations dashboard
  • 10Document and contract generator

The build

What I build

This is the build half. It comes after the thinking, once software is clearly the right move.

One action, everything in place.

A new job comes in through your booking page. The customer lands in your records, the slot in your calendar, the line in your accounting. One action, everything in place. Entered once, and right everywhere.

The hours your team spent typing the same thing into three places turn into finished jobs, returned calls, and people getting home on time.

Mistakes caught before they cost you.

Every quote, contract, and report runs through an automatic check before it leaves the business. Missing fields get flagged. Numbers get checked against your data. And every step leaves a trace, so when someone asks who approved what, the answer is one click away.

The 11pm doubt, wondering whether the quote you sent had the right numbers in it, goes away. The software checked it before it left the office.

The software fits your work, not the other way around.

The buttons say what your team actually calls things. The fields hold what your business actually tracks. The flow follows how the work really happens, in your trade, at your size.

Your team stops fighting the software and actually uses it. Training a new hire takes an afternoon, not a month.

Everything in one place, and you can trust it.

Sales, appointments, accounting, delivery. Today they live in five separate places and a spreadsheet. I connect them so a customer's record is the same everywhere, and anyone on the team can answer a basic question in one place.

A question about your business gets answered in five seconds, not after five calls and four open tabs.

The thing you've been told is impossible.

A camera that checks work quality on its own. A phone call that becomes an entry by itself, with nobody typing. A screen that watches the operation live and flags trouble early. What cost a fortune a few years ago is now affordable, fast, and yours.

What your competitors will pay for in two years, you have running next month. While they're still talking about it, you are booking the work it brought in.

Most jobs delivered in as fast as 7 days. Larger ones, up to 30. *

* The 7-day and 30-day timelines apply to focused, clearly-scoped software where you provide the needed data, access, and answers without delay. More complex work takes longer, and we agree the exact scope and timeline together before any work starts.

No catch

What you get either way

Straight answers

I'll tell you when the answer isn't software, or isn't me. I'd rather lose the job than build you the wrong thing.

You own the code and data

Full source and a clean handover whenever you want it. Walk away anytime with everything.

No vendor lock-in

Standard, boring tech. No proprietary platform holding your business hostage.

GDPR-ready

Privacy built in, and compliance set up for wherever you actually operate.

NDA-friendly

Discretion is the default. Want paperwork on top? I'll sign yours before we talk.

Transparent pricing

Fixed scope, agreed up front. No surprise invoices, no meter running.

Let's find where your business is leaking, and fix it.

One discovery call, no commitment. I'll tell you where the real problem is, whether the fix is software or not, and if I'm not the right person, I'll say so.

The whole system

The leverage is usually where it all connects.

Today none of it can be separated, the software, the operation, the marketing, the AI. Coming from outside your day-to-day, I see where your real leverage is, and point you at it before you spend the money.

So we don't have to start with software. We can start with the business.

The diagnosis

I find where your time and money leak.

A paid deep-dive into how your business actually runs. You walk away with a prioritized plan: what to fix, what to build or buy, and what to leave alone. Sometimes the answer is custom software. Sometimes it's a change you can make on Monday. Either way, you know before you spend.

Start with a diagnosis

If the diagnosis says you don't need me, I'll tell you. You keep the plan either way.

Fractional COO

By invitation

For a few, I step in and help run it.

For a handful of owners each year, I take an operational seat for a season and help run the business, not just advise from the outside. It's a bigger commitment on both sides, so we start it only when it's clearly the right fit.

Questions

Frequently asked questions

More than software. Pricing that undercharges, an offer people don't quite get, a sales process that leaks deals, ad spend going to the wrong people, an operation that only works when you're in the room. Basically the things that quietly cost a small business money. I've run my own for almost two decades, so I look at the whole picture first, then fix what's actually hurting, whether that's a conversation, a change in how you work, or software I build.

No catch. The 7 days is for a working first version that solves your core problem. It runs on your own web address, with your real data, and your team can use it on day seven. What it isn't is a fully polished, finished system with every rare case handled. That's what the next stage is for. Bigger jobs, where I connect several apps and roll it out to the whole team, usually take two weeks to two months. The 7 days is real, and it's the start of the work we do together, not the finish line.

Both, and often the advice comes first. Plenty of owners don't need a new system, they need someone who has run a business to look at the whole operation and say what's worth changing. That's the diagnosis: a paid deep-dive that ends with a prioritized plan. Sometimes it includes software I then build. Sometimes it's changes you make yourself. Either way the answer is grounded in having actually run businesses, not just built software.

That's exactly why the first week exists. You find out before committing to a bigger job. On day seven you see working software running, and you decide whether to continue. If it doesn't solve the problem we agreed on, you don't pay for the next stage, and the working tool I built is still yours. It's set up so neither of us is locked in past the point where it makes sense.

You do, fully. The code, the data, the setup, the documentation, all of it is yours from day one. If you ever want to move it elsewhere, run it somewhere else, or stop working with me, you walk away with everything you need to keep going. No lock-in, no hidden fees, no part only I can touch. If we work together long-term, it's because it pays off for you.

Mostly service businesses, where the day runs on appointments, jobs, customers, and repeat work. The problems I solve cut across trades: scattered data, too much manual work, software that doesn't fit, and things that weren't possible a few years ago. Whether you run a detailing studio, a dental practice, a financial advisory, or an inspection company, the patterns are similar. If you're not sure yours fits, send the form. I'll tell you straight if it doesn't.

Most businesses already have a customer list, an accounting program, a scheduler, and a few subscriptions. The goal isn't to throw it all out, it's to make them finally work together. I connect your existing apps so data goes where it needs to, without anyone copying it by hand. If something works well but stands alone, I keep it and build the bridge. If something genuinely holds you back, I replace it. Either way, your existing data comes with you, cleaned up.

Your business data is treated the way I'd expect for my own. Every app gets a proper login, and a two-step login where it matters. It's protected against break-in attempts, and I watch the system so I hear about anything odd early. Your data is backed up regularly and automatically, to more than one place, so even in the worst case nothing is lost. It meets GDPR by default, and if you handle medical, financial, or other sensitive data, I tighten it further. That's planned in from day one.

Then it takes longer. The 7 days and 30 days are reference points, not ceilings. Bigger jobs, with lots of connections, more complex rules, or smart features that need tuning on real data, usually run six to twelve weeks. The price scales with the size of the work, and the timeline is honest about what's needed. What stays the same at any size: you see finished pieces early and often, you decide at the end of each stage whether to continue, and you're never left in the dark for six months.

No. The whole point is that you don't have to become a tech person. The call is in plain language, the daily videos during the build are two minutes and anyone can follow them, and the final walkthrough is about getting your team using the tool. If the details interest you, I go as deep as you like. If they don't, you'll never see a line of code. Your job is to know your business. Mine is to turn that into software.

Few, and confidential, both on purpose. The one-week timeline only works if your project gets full focus that week, so I take on a small number at a time. Discretion is the default, paperwork or not. I've finished dozens of jobs under NDA, and the work, the data, and even the existence of the project stay between us unless you decide otherwise. If you'd like paperwork on top, I'll sign your NDA before the call. Availability is limited and fills up, so the call is also a check on whether a slot is opening that fits your timing.
