Tax Lane Academy runs seminars on tax for professionals. I designed and built taxlane.nl so the team can publish a seminar, sell it online and run everything around it from one admin. It went live on 13 October 2026, three days after my first commit, and I've looked after it since.

Seminars that sell online
A seminar page shows the topics, the speakers, the price and where to be, with the sign-up form right below. A whole team signs up and pays in one go, by iDEAL or invoice, and the early-bird price ends on its own date. Late invoices get a reminder from the site, and a full seminar opens a waiting list, so selling a seat takes no phone calls and no spreadsheets.
One admin for everything
The team publishes seminars, follows sign-ups and payments, and mails attendees from one admin, on a laptop or a phone. Nobody needs a password, and each role sees only its part: a colleague can work the attendance list without seeing any amounts. A logbook records who changed what.
Planning in one place
Every seminar has a run sheet from the first meeting to the follow-up, with an owner for each step. Adding a step is one typed line, and Claude suggests when it happens and who takes it. On the day itself, the hour-by-hour plan replans from a sentence like “catering can only start at 10.20”, and nothing moves until someone applies it.
Promotion you can measure
The flyer, a brochure, the QR code and the social images are made from the seminar's own details, so a changed time is right everywhere at once, with no designer needed. For LinkedIn, Claude drafts two versions of a post toward a goal, such as the early-bird deadline. Every post gets its own short link, so the team sees which posts brought in clicks, sign-ups and revenue, and the best ones become examples for the next.
One brand everywhere
The look started from Tax Lane's flyer. I carried its colours and slanted planes onto the web and into the admin, so a seminar page, the flyer and a LinkedIn image all read as one brand.
Working with me
I designed taxlane.nl, built it and still look after it, so nothing got lost between a designer and a developer. If people sign up or pay for what you run, I can build you something like this, from first sketch to live.
