Free, with ads. No in-app purchases
Ads
A banner on the home screen, the invoice list and every calculator, an occasional full-screen ad after an invoice is shared or printed, and two optional reward videos on the preview: Modern and Minimal templates for 24 hours, or no footer line on one invoice; the Classic template is always free.
Account
No account or sign-up

Invoices, PDF creation, printing to a local printer and all calculators work without internet; ads and reward videos need a connection.

Your data
The app itself sends nothing; an invoice leaves the phone only as a PDF you choose to share or print, calculator numbers never leave it, and only the AdMob SDK sends data such as device identifiers for ads.

Business details, invoices and settings are stored in the app's private storage on the phone; Android's device backup may include them if the user has backup turned on.

A PDF invoice maker for your phone: send a professional invoice in a minute, and keep the everyday business maths in the same place.

It works as a simple invoice generator: enter your business details once, and every invoice stays in a list on your phone, ready to share again, duplicate or mark as paid.
Business calculators
Loan EMI calculator: monthly payment, total interest and a full payment schedule
Savings growth: regular deposits and compound interest, year by year
GST, VAT and sales tax calculator: add tax to a price or take it out of a price that already includes it
Margin calculator: find your margin and markup, work out the price for a target margin, or stack two discounts
Tip and split: share a bill fairly, with an option to round each share up
Private by design
Your invoices and business details stay on your phone. The app has no server of its own and needs no account. Invoices are created on the device and only leave it when you choose to share or print them. The calculators give estimates for information only; real rates, fees and returns vary.
Biz Toolkit is free and contains ads. You can optionally watch a short video to use the Modern and Minimal invoice templates for 24 hours, or to remove the small "Created with Biz Toolkit" line from the invoice you are about to share or print. The Classic template and every other feature stay available without watching anything.
