About Us

Toolsque is a set of free tools that run in a web browser. We are a small team of developers, and we write and maintain every one of them. They are grouped by trade and task: QR code generators, readers and repair tools, barcodes, construction quantities and building rules, and pricing and break-even arithmetic for small businesses. No account. No email wall. Nothing that expires.

Why this site exists

We kept needing the same calculations while working with small contractors and freelancers, and kept finding the same three problems with what was available. The result arrived with no formula attached, so there was no way to tell whether it applied to the situation in front of us. The tool wanted an email address before it would show a number. Or it quietly assumed a jurisdiction, a year or a code edition without saying which.

So each tool here prints the formula it used, states its assumptions, and works without an account. That is the whole idea. It is a narrow one, and it is the reason the site has no reviews, no software comparisons and no rankings of any kind. It is tools, and the guides that explain them.

The numbers stay on your machine

Every calculator is client-side JavaScript. When you type a labor cost into the job costing calculator, that figure is handled by code already sitting in your browser and is never posted to a server. The QR tools work the same way. A WiFi password you encode is turned into pixels locally, and a screenshot you drop into a scanner is decoded in the page rather than uploaded for processing.

You can verify that instead of trusting it. Load a tool page, disconnect from the internet, then use it. It keeps working. Or open your browser's network panel and watch while you type; the calculator makes no requests.

How a tool gets built

1. Start from a published source. Not from someone's blog post. The table below lists the main ones.
2. Write the arithmetic to match it, and print the formula on the page under the result, so you can check every step.
3. Test against worked examples calculated by hand from the specification before anything is published.
4. Push the edges: zero, a negative, a number typed with a comma in it, and a value large enough to break the display.
5. Check the rounding, which is where quiet errors live. Money rounds to cents. Materials round up to whole units you can buy.
6. Publish with sources and a date, then re-check when a standard or a figure changes.

Showing the formula carries more weight than it sounds like. A worked example from the break-even tools: a $5.00 latte with $1.40 of milk, beans, cup and lid contributes $3.60. Against $14,400 of monthly fixed costs that is 14,400 / 3.60 = 4,000 cups, about 133 a day. All three steps are shown. If you think your cup costs more than $1.40, you can argue with a specific number rather than with a black box that just says 4,000.

What checking looks like

The recurring failure is definitional. Markup and margin get swapped constantly. A $100 cost with 40% markup sells at $140, and the margin on that sale is 28.6%, not 40%. The contractor markup calculator states which of the two it is computing, because quoting all year on 28.6% while budgeting as though it were 40% compounds into a real gap by December.

Rounding order is the other one. 7.41 cubic yards of gravel is bought as 8, and a waste factor applied after rounding gives a different answer than one applied before. Both orders get tested, and the one the trade actually buys by is the one that ships.

What this site deliberately does not do

• No personalised financial, legal or tax advice, and none should be read into a result.
• No reviews, rankings, sponsored tools or paid placements.
• No affiliate links in the tools or the guides.
• No accounts, email walls or codes that stop working when a trial ends.

We are not accountants, licensed contractors or solicitors. A figure from this site is a starting number for a conversation with someone who is. Codes carry local amendments: a span result does not survive contact with an inspector working to an adopted local variation, and it knows nothing about point loads, notching, or timber grade beyond what you entered. Cost estimators use the rates you supply, so if your regional prices are out by 15%, the total is out by 15% in the same direction and will look perfectly confident about it.

Finding an error

Wrong answers are the reports we want most. Use the contact link in the footer and include four things: the tool name, the exact values you entered, the figure it returned, and the figure you expected with a source or a hand calculation behind it. Those go ahead of feature requests. When a formula turns out to be wrong, the code and the printed formula get corrected in the same change, so the two never drift apart.

Advertising and privacy

Toolsque shows advertisements from Google AdSense to help cover hosting and the time spent maintaining it. Nothing on the site is ranked, recommended or placed in exchange for payment.

The calculators themselves send nothing anywhere, as described above. Anything optional, such as a contact form submission, only happens because you chose to send it. The privacy policy lists every service that runs on the site and what it does.

Who maintains Toolsque

The tools are built and maintained by the Toolsque Team, a small group of developers with backgrounds in IT consultancy and web development. Our technology partner, GoProIT LLC, supports development and hosting. We are not a media company and we do not publish sponsored tools or paid placements. Every tool is written, checked and corrected by the same people, and the method we follow is written up in how we build and test.

Contact

For questions, corrections or feedback, use the contact form, or email hello@toolsque.com with the tool and the inputs you used. We will check it against the source and publish a correction if it is wrong.
