How a Plumbing Company in NRW Saves 11 Hours per Week Through Automation

How a Plumbing Company in the Rhineland Reclaimed 11 Hours per Week

A plumbing business with 8 employees in the Neuss area had a classic problem: The tradespeople were productive on-site – but work was piling up in the office. Quotes that took three days to create. Invoices that only went out at the end of the month. Customers who called because they hadn't heard anything. This is the story of how we changed that.

The Starting Situation: Good Work, Bad Processes

Thomas K. has been running his plumbing and heating business in the Rhine-Neuss district for over 15 years. His team is well-coordinated, the quality is excellent, the order books are full. Yet he constantly felt like he was falling behind.

The problem wasn't on the job site. It was in the office.

When we had our first conversation with him in October 2025, he described three specific pain points:

1. Quotes Took Too Long

After a site survey or initial meeting, it took an average of 2-3 days before a quote reached the customer. Not because the calculation was so complex – but because the office assistant manually typed the quote in Word, looked up prices from an old Excel spreadsheet, and then sent it by email. During that time, some customers had already called the next contractor.

2. Invoices Went Out Too Late

Completed jobs were documented on a notepad. The invoicing then happened "at some point," often only at the end of the month. This led to liquidity problems and regular payment delays.

3. Customers Received No Updates

Between inquiry and first contact, between order and completion notification, there was hardly any automatic communication. Customers called to ask if their quote had arrived. These calls cost time – and nerves.

The Analysis: Where Time Was Really Lost

Before we automated anything, we observed for three weeks. Not to impress – but because automation that speeds up the wrong process does more harm than good.

Eleven hours per week. That's almost 1.5 working days – every week, paid from company profits, without direct value.

The Solution: Three Automations, One System

We didn't implement a large ERP system. No expensive software. No months-long implementation. We built three targeted automations that seamlessly work together.

Automation 1: Automatic Quote Generation

When Thomas or one of his employees enters the line items into a simple input form after a site survey, this happens automatically:

1. Line items are matched with current prices from the central price list
2. A quote is generated as PDF – with logo, address details, and payment terms
3. The PDF is automatically sent to the customer via email
4. A copy is stored in Google Drive under the correct customer project
5. Thomas receives a brief notification: "Quote sent to [Customer Name]."

What used to take 45-60 minutes: now under 5 minutes of input, rest fully automatic.

Automation 2: Invoice Sending After Job Completion

The technician enters on their smartphone after completion: Job done, hours, materials. This automatically triggers:

1. An invoice is created based on the job data
2. The invoice is sent to the customer via email within minutes
3. A payment reminder is automatically sent after 14 days
4. After payment receipt, the job is marked as "paid"

Automation 3: Automatic Customer Communication

Every customer now automatically receives:

• After inquiry: Confirmation email within minutes
• After order confirmation: Email with appointment and technician info
• Day before appointment: Automatic reminder email
• After completion: Thank you email with request for Google review

These four emails didn't happen before. Now they run fully automatically.

The Results After Three Months

Time Savings:

The 11 hours per week have largely disappeared. The office assistant now focuses on more complex tasks.

Liquidity:

The time between job completion and payment receipt has shortened by an average of 8 days.

Customer Satisfaction:

The number of Google reviews has more than doubled in three months – solely through the automatic request after job completion.

Investment vs. Return:

The ongoing hosting costs are under 20 euros per month. Thomas achieved return on investment in less than six weeks.

What We Learned From This

Every time we talk to a trades business, we hear variations of the same sentence: "We've always done it this way."

That's not a reproach. It's a sign that daily work takes up so much space that there's no time to reflect on one's own processes.

Automation isn't a luxury for corporations. It's a tool – just like a good saw. Once properly deployed, it works for you every day. Without vacation, without errors, without extra effort.
