App and web development · Ennetbaden, Aargau

I’m Maximilian. I dream along and build whatever comes out of it. For the startup as much as for the café around the corner.

Case study · Structon GmbH, interior construction

A back office that runs the business.

For Structon I didn’t just build the website, but the whole system behind it. Email, quotes, building sites, accounting and payroll all come together there today. One system instead of a patchwork of tools.

  1. Enquiry
  2. Quote
  3. Order
  4. Site
  5. Invoice
  6. Accounting
  7. Salary certificate

Inboxes with brains

Shared inboxes for the team. The AI sorts, files every email under the right project and drafts the reply.

Quotes people enjoy reading

A page designer for quotes, brochures and project books. The client accepts with one click in the portal.

QR invoices

Partial and final invoices to the Swiss standard, with earlier partial invoices deducted automatically.

Accounting included

Double-entry bookkeeping on the Swiss SME chart of accounts, bank reconciliation, VAT returns and year-end closing.

Payroll without Excel

Payroll runs with AHV, BVG and withholding tax, payslips and the salary certificate at year end.

Building sites under control

The AI prepares site visits, photos work offline too. Fitters get instructions with pictures and video.

Team and appointments

Time tracking with statutory break deduction, a team calendar and online booking for clients in five languages.

Client portal

Progress, documents, quotes, invoices and chat in one place. Installable as an app on the phone.

Plus: two-factor login, roles and permissions, daily backups and an alert whenever something gets stuck.

AI in your workflows

AI that pitches in. Not just chimes in.

I build AI in where it genuinely saves time: into the workflows still done by hand today. It reads, sorts, summarises and reminds you of deadlines. You take care of what only you can do.

Get your workflows reviewed
01

Mail that sorts itself

Scanned letters are read and filed. Sender, deadline and next step are already there before you have binned the envelope.

02

Enquiries that arrive pre-sorted

Emails and forms land under the right topic, with a summary and a draft reply you only have to approve.

03

Snap the receipt, the booking is ready

The AI reads receipts from a photo or PDF and suggests the booking. Supplier invoices it fishes straight out of the inbox. Nothing is booked until you click.

04

A phone that picks up by itself

A voice assistant takes calls and answers the common questions. In natural language, evenings and weekends included.

05

An assistant that knows your product

It answers your customers’ questions from your own help pages and documentation, instead of making things up.

06

One sentence, and there’s your page

Describe briefly what you need and the AI drafts the page, colours and images. Changes work the same way: “Make the background greener.”

07

First drafts at the push of a button

Training plans, checklists, listing texts or brochures: the AI delivers the first draft, you decide what stands.

08

Checked before it goes live

Posts, comments and uploaded images are checked automatically before they appear in public.
