Editorial policy
Last updated 14 October 2026
Our guides and calculators are meant to be useful and correct. This page explains how we research, source, date and correct them.
Sources
We use primary sources first: laws and official decrees, ministry and regulator pages, central banks and official statistics. News reports are used only to point to an official announcement. Every guide lists its sources at the end, and every number that can change shows the date we checked it.
Dates and updates
Each guide shows the date it was last updated. We re-check rules when a law, rate or fee changes, and we change the date only when the content is actually checked. Expected dates, such as Ramadan and Eid, are labelled as expected.
What we do not do
- We do not give legal, tax, medical or religious rulings. Guides explain the published rules and tell you where to get an official answer.
- We do not claim that any tool makes you compliant with e-invoicing, tax or other regulations.
- We do not invent authors, reviews, ratings or testimonials.
- We do not name or compare ourselves with other companies' products.
Arabic
Every page is written in Arabic too. Arabic text is checked by automated tests for spelling patterns, punctuation and numbers, and it is marked as pending review until a native-speaking editor has read it. Religious and legal Arabic needs a specialist.
Corrections
If you find an error, email services@zkdigitals.com with the page and what is wrong. We check it against the source, fix it and update the date.
Advertising and sponsored content
Advertising never changes what a tool or guide says. Any sponsored article is labelled as sponsored at the top, and its links are marked as sponsored for search engines.
