45 Free Tools for Nigerian Businesses, Students and Developers

Today we're launching 45 free online tools at odotservices.com.ng/tools. You can make invoices, build a CV, calculate your CGPA, estimate building materials and much more. They're all free to use, with no sign-up and no account needed.

We built them because small businesses, students and freelancers in Nigeria do the same everyday tasks again and again. Many of the tools online are made for other countries, hidden behind a paywall, or asking you to register before you can do anything. Ours are set up for how things work here: 7.5% VAT, naira amounts, WhatsApp links, JAMB aggregates, and 6-inch and 9-inch blocks.

Open any tool, use it, and download your result. That's it.

What's inside

The 45 tools fall into eight categories. Click any name to open it.

Who they're for

Business owners and sellers. Create a professional invoice with VAT and discounts, then download it as a PDF. Give customers a receipt with a PAID stamp in seconds. Send a quote and turn it into an invoice once it's accepted. Use the Profit Calculator to check your margin before you set a price.

Marketers and social media managers. Make a WhatsApp link with a ready message, so customers can chat with you in one tap. Turn your page or Wi-Fi login into a printable QR code. Tag your links with the UTM Builder to see which posts and ads actually bring visitors.

Job seekers. Build a CV in one of six designs and download it as a PDF. Then generate a cover letter from your CV that matches its design. Resignation, application, internship and reference letters are also there.

Students. Work out your GPA and CGPA on the 5-point or 4-point scale, plus your class of degree. Combine your UTME, Post-UTME and O'level results into a JAMB admission aggregate. Cite sources in APA, MLA or Harvard, and plan your reading with the Study Timetable.

Builders, landlords and property buyers. Find out how many 6-inch or 9-inch blocks a wall needs, and the cement and sand to lay them. Estimate tiles, paint and roofing sheets before you buy. Renters can see the full cost of moving in, including agency, legal and caution fees.

Developers. Format and validate JSON, generate UUIDs and strong passwords, create hashes, convert Unix timestamps and test a regex, all in your browser.

Coming soon

We're already working on a Salary Calculator (take-home pay after tax, pension and NHF), a URL Shortener, PDF to Image, and a Currency Converter.
