01The challenge
When choosing an accounting firm, business owners ask two questions: what does it cost, and am I paying too much tax? Most accounting sites show a list of services and a form. This is how I would build a site for an accounting firm in Wola, Warsaw, that looks after sole traders and small companies: the answer to the second question right on the page, and from there a short path to a package.
02What I did
-
A calculator on the first screen
Instead of a slogan, the first screen asks “Lump-sum, flat or progressive tax?” and has three fields: revenue, costs and industry. The amounts for the three options are written in like a ledger, and a highlighter sweeps across the best one. The full calculator further down covers the type of social security contributions, sickness insurance and filing jointly with a spouse.
-
Numbers with sources
The 2026 rates, thresholds and contributions come from zus.pl, podatki.gov.pl and biznes.gov.pl, each with the date it was checked. Under the result the page says plainly what it simplifies: 12 equal months, no reliefs and no other income. The result is labelled as an estimate, and I checked the maths against examples worked out by hand.
-
The highlighter picks the package
The packages sit in one table, like a ledger. The calculator result highlights the package that fits the business, and the “Send the result to an accountant” button carries the numbers into the form, so nothing needs retyping.
-
A tax deadline calendar
The page has a calendar of tax and social security deadlines for the next three months. It works itself out on the day of the visit and moves a deadline to the next working day when it falls on a weekend or holiday.
-
Ledger paper
The page sits on paper with pale blue lines, a red margin line runs down its full height, and a lemon highlighter is the only accent. Numbers use a typewriter-style font, so the digits line up in columns, and the paper lines never cross the letters.
-
Honestly labelled
The firm and its team are fictional, the number is all zeros, and the package prices are sample assumptions. The photos are AI-generated and labelled that way. On the demo the form does not contact anyone.
03Result
An accounting firm website that answers the tax question on the first screen, then leads the business owner to a matching package and a conversation with an accountant. Speed 96/100 on mobile and 100 on desktop, accessibility 100, and nothing jumps while the page loads.

How customers find this website
- The title asks the same question the client does: lump-sum, flat or progressive tax, with a calculator for 2026.
- Google knows it is an accounting firm and knows its packages and service area, because they are written on the page in a way it reads directly.
- The most common questions are set up so Google and AI assistants can quote the answers.
- The demo is hidden from search engines, because the business is fictional.
