Using BiznTools
About
Practical tools to run your business: finance, invoices, time, pay and documents.
One job. Done properly.
BiznTools builds practical tools for everyday business work. Check your numbers, prepare a client invoice, work out time and pay, or get your documents ready. Each tool has a focused job and gives you a result you can use without creating an account.
The current collection covers profit margin, markup, break-even planning, cash runway, a USD Invoice Generator, a Time Card Calculator, gross salary conversion with offer comparison, local PDF merging, JPG/PNG-to-PDF conversion and PDF pages to JPG/PNG images. No account or subscription is needed.
Understand the number before acting on it
A result is more useful when you know what it includes. The calculators explain their inputs, show worked examples and describe the cases where an answer is unavailable. You can copy or print a summary with the assumptions that produced it. Document tools explain which files and features they support before you create an output.
These are simplified planning tools. They do not know your full business circumstances or replace professional advice. Consider costs, timing and risks outside the model before making a decision.
