How we write and check our pages.
Horn Dev builds websites, and some of our pages explain rules, prices and fees that other people rely on. This page says how a figure or a rule gets onto our site, what we refuse to publish, and what we do when we get something wrong.
Who writes and runs these pages.
Horn Dev is a practice of Horn Software Architects (Pty) Ltd, run by Petrus Horn and Jillian Godley in Rustenburg, North West. See About for who we are and how projects work. Our rules, cost and industry pages are published under the Horn Dev name.
Every rule and figure needs a source and a date.
- Each rule, price or fee on our industry, trade-rules, cost and calculator pages links to where it came from and shows the date we last checked it.
- We prefer primary sources: the gazetted regulation, the regulator's own page or the municipality's own document. When we can only find a secondary source, such as a vendor's price page, the page says so and calls the figures indicative.
- Our own build refuses to publish a page whose rule has no source, whose source is not a secure link, whose price or percentage is not in a cited source, or whose check is more than a year old. At 180 days it warns us to re-check.
- Prices we quote for Horn Dev must match our pricing page, and a price for anything else must appear in a cited source.
- We avoid promises and rankings. Words such as guarantee, number one and top of Google are blocked from these pages.
- Pages about rules say they are background, not legal advice, and tell you who to ask for your own situation.
Right now that is 27 sourced facts across 13 pages. The oldest check is dated 24 Oct 2026 and the newest 24 Oct 2026.
Things we leave out on purpose.
- Reviews, testimonials or case studies we cannot attribute to a real client with their permission. Our reviews page shows what we have, and says it is little.
- Registration numbers, certificates or verifications we have not seen, for us or for anyone else.
- Client names or business names without permission.
- Statistics we cannot trace. Where we publish our own data, such as the business website research, we state the sample, the date and the limits.
We sell websites.
Our industry and trade-rules pages exist partly to show what a good website for a trade should contain, and they link to our services. When we quote another company's prices, we cite the page and say what that company sells. A figure from a competitor or a lead marketplace is reported as published, not endorsed.
If we get something wrong.
Tell us on WhatsApp, by phone on 081 334 8488, or by email to petrus@hornsoftwarearchitects.co.za. If the source says something different from our page, the source is right. We fix the page, update the date we checked it, and list the correction below when it mattered.
No corrections have been published yet. When we fix a mistake that mattered, it will be listed here with the date and the page.
