What's New on Zen2B2

New: employer cost, taxes and company registration by country

A new collection under /countries/ covers Türkiye, Azerbaijan, Turkmenistan, Bulgaria and Georgia: an overview per country, an employer-cost calculator that applies each country's verified 2026 contribution and income-tax rules to any monthly salary, and a company-registration page with fees, capital, registry and the first taxes a new company meets. Every published number links to the official page it was read from and shows its effective date. Where we could not confirm a figure at an official source, the page says "not published" instead of printing a guess; that is why some cells are empty, and why Turkmenistan's page shows the employer's cost but not the employee's net pay.

Two new calculators: Gas Fee and Compound Interest

• Gas Fee Calculator: turns gas units and a gas price in gwei, or an EIP-1559 base fee plus tip, into a fee in wei, ETH and, if you type an ETH price, US dollars. It works offline with the numbers you enter; it does not fetch live gas prices or quotes, and it says so on the page.
• Compound Interest Calculator: a starting deposit plus regular monthly or yearly contributions, at the compounding frequency you choose, with a year-by-year table. The rate is always your assumption, not a promised return.

Both pages print their formula, walk through a worked example, and carry the same guide structure as every other tool. Neither is financial advice.

Full guides on all 34 tools; password generator now uses cryptographic randomness

The remaining 24 tool guides were extended in the same shape as the finance calculators: how the tool actually works, a worked example with real figures, the mistakes we see most, and which other tool to use when this one is wrong. Every tool page now carries between roughly 700 and 1,000 words of explanation. While writing the Strong Password Generator guide we found the tool picked characters with the browser's ordinary random function; it now uses the cryptographic one (crypto.getRandomValues), which is what a password generator should have used from the start.

Full guides on the ten finance calculators

The Profit Margin & Markup, Break-Even, Currency Converter and Timesheet calculators had no guide at all; they now have one. The Discount, VAT / Tax, ROI, Payroll, Sponsorship and Expense Tracker guides were extended. Every one of the ten now states its formula, walks through a worked example with real figures, lists the mistakes we see most, and says when a different tool is the right one. Visible text on these pages went from roughly 300–450 words to 770–1,020.

New About, Contact and Updates pages

The site now has a proper About page that says who makes Zen2B2 and how the content is produced, a Contact page with a working address, and this release log. The old third-party headline feed at this address was removed.

Three reference collections and an A–Z tools index

• Pricing math: 69 pages that turn a markup into a margin (and back), discount tables from 10% to 90%, and a master conversion table, each with a prefilled calculator and a worked example.
• Business documents: 28 pages comparing the documents in an order-to-cash flow (quote, sales order, purchase order, proforma invoice, delivery note, invoice, credit note, receipt) and listing what each one must contain.
• Creator rates: YouTube sponsorship rate cards by channel size and by niche, built on a published rate model with the assumptions spelled out on every page.
• All Tools A–Z: one page that lists every tool and every guide, so nothing on the site is more than two clicks from the homepage.

All of these pages are generated from data files and pass an automated check before deployment: unique titles, no shared paragraphs between pages, a minimum of 400 words of explanation outside the tables, and every internal link resolving. The sitemap is now generated from the same source, so it cannot drift from what is actually on the site.

Longer guides, expanded blog posts, consent fix

• Step-by-step guides with worked examples were added to 30 tool pages, and 10 tool pages that had no main heading got one.
• The five oldest blog posts were expanded with new sections and a FAQ each.
• The cookie consent banner was corrected: visitors from the EEA, the UK and Switzerland now see analytics and advertising storage kept off until they make a choice; everywhere else the defaults apply as before. See the Privacy Policy.
• The Audio to Video converter was added to the sitemap, a third-party icon library was pinned to a fixed version, and a dead visitor-counter script was removed from every page.
• HTTP requests now redirect to HTTPS, and standard security headers are sent with every response.

Site completeness pass

• New Privacy Policy and Terms of Service pages, a proper 404 page, favicons and social preview images.
• A Google Consent Mode cookie banner was introduced site-wide.
• Every tool page gained a FAQ section, and the Help Center was rebuilt to answer the questions people actually search for.

Public launch

Zen2B2 launched publicly with 34 free, browser-only tools for small businesses and freelancers: invoicing and quotations, pricing calculators, a shift planner, PDF utilities, image converters and text tools. Nothing you type is uploaded; each tool runs in your browser and saves, if it saves anything, to your own device.

Mobile rebuild

A hamburger menu, a focus-mode toggle for the calculators, a landscape two-panel layout and a long list of small-screen fixes went out over several releases. The shift planner got a "copy Monday to the whole week" quick-fill.
