As answered by people managing Freelero and Open Devdocs.
Freelero's answer
Freelancer Business Toolkit brings together practical calculators for the most common financial and pricing decisions freelancers face. Instead of using separate tools for hourly rates, project pricing, billable hours, retainers, rate increases, effective hourly rates and invoicing, freelancers can access them in one free toolkit. No account is required.
Freelero's answer
Freelancer Business Toolkit is a free, focused toolkit for freelancers and solopreneurs who want to handle common pricing, profitability and invoicing calculations quickly. It provides several specialized calculators in one place, requires no account, and is designed specifically around common freelance business scenarios.
Freelero's answer
The primary audience is freelancers, independent professionals and solopreneurs who need to calculate rates, price projects, estimate billable hours, plan retainers, manage rate increases and handle basic invoicing tasks.
Freelero's answer
The idea for Freelancer Business Toolkit came from a simple problem I saw in my own circle. A friend who works independently often struggled with calculating his hourly rate, project prices and other financial details, including how percentages and expenses affected his rates.
I realized that many freelancers and self-employed professionals face similar problems and often have to use different tools or calculate everything manually. This led me to create Freelancer Business Toolkit: a free collection of practical calculators designed to make common freelance business calculations simpler and easier to understand.
Freelero's answer
Freelancer Business Toolkit is built with Next.js and Node.js, and is hosted on Vercel.
