Hi, I'm Johan, and I'm the technical muscle behind Software Plumber.
After 35 years spent building robust, rock-solid software systems for both SMEs and large corporations, I decided to focus my decades of expertise right here in South London. I saw a clear need for reliable and personal software expertise available to local businesses. My goal is simple: to be your local, trustworthy and dedicated partner for those exact needs.
I believe in transparent pricing that reflects the time and value I deliver. Before any work begins, I provide a detailed time estimate. Once we agree on the plan and a 50% deposit is received, I dive in.
Many projects are dynamic — as you see the work come together, you might want to pivot or refine the direction. This is natural and welcome! Refactoring often leads to better solutions. However, major revisions that significantly change the original scope may require a small, pre-agreed adjustment to the final payment.
I use tiered pricing to ensure you get a better value on larger projects. Fractions of time will be rounded to the nearest half day/week/month.
| Duration of Work | Rate | Hourly Equivalent |
|---|---|---|
| Micro-Tasks (1 - 8 hours) | £50 / hour | £50 / hour |
| Small Projects (1 - 5 days) | £360 / day | £45 / hour |
| Mid-Size Projects (1 - 3 weeks) | £1,600 / week | £40 / hour |
| Large Projects (more than 4 weeks) | £5,600 / month | £35 / hour |
Ready to finally fix that leaky system or build the tool that will grow your business? Get in touch with me directly—I'm always happy to talk through your challenge and give you an honest perspective on the best way forward.

The first step is understanding your vision. Please follow this simple structure and send it to me as your initial email:
Tell me your overall goal. Focus on the why and what. What will this software allow your business to do that you currently can't?
Take that big dream and break it into smaller topics or features. Look at the categories we listed on this page (e.g., Websites, Dashboard Systems, Bespoke Apps) as example to help structure your thoughts.
For each main topic, break it down further into specific bullet points describing what that part of the system needs to do.
Example structure for your email:
- Topic 1: Online Booking System
- Needs to check staff availability in real-time.
- Must accept £10 non-refundable deposits via Stripe.
- Must send automated SMS confirmation 1 hour before the appointment.
- Topic 2: Dashboard Monitor
- Needs to display today's sales vs. target on a single screen.
- Needs to flag inventory items that are below stock level 5.
Once I receive your detailed email, I will study your needs thoroughly. I will then send a response, and we can quickly agree on a date and time to meet. We can meet at your business, a quiet local cafe, or any location that is convenient for you to discuss the project in detail.
I look forward to hearing about your project!
