About Invoice Simple
Invoice Simple is a business application that puts invoice creation and billing management in your pocket. It is developed by Invoice Simple and distributed under the package name com.aadhk.woinvoice, so it sits alongside your other work tools as a dedicated invoicing workspace.
Core invoicing focus
The app belongs to the business category, and its name signals the task it was written for: turning the everyday job of raising invoices into something you can handle from a handset. Rather than treating billing as an afterthought, it positions invoice handling as the central activity the app is organised around.
Android version compatibility
The build requires Android 8.0 or newer. Devices running that baseline, or any more recent release of the platform, are the intended target, while handsets below it fall outside the stated support range. Checking your system version before you install saves you from a package that will simply not launch.
Storage space to plan for
The package weighs 213.3 MB, so it is not a lightweight add-on. Make sure your device has comfortable room to spare before you begin, since low free storage remains one of the most common reasons an installation stalls partway through.
Current version details
This listing carries version 6.15.1, dated 2026-10-02. The content rating has not been published here, so anyone assessing the app for a shared or managed device should note that the rating field is recorded as unknown.

Frequently Asked Questions
Which devices are compatible with this build?
Compatibility follows the single requirement listed for the package: it needs the stated baseline Android release or anything newer. Handsets running an older release will not satisfy it, so confirm your system information before installing. Beyond that line, the listing publishes no supported-device list, chipset guidance or hardware notes, so compatibility with a particular model has to be checked on the handset itself.
How much free storage should I keep available?
The download is 213.3 MB, so leave more than that free so the package has room to unpack comfortably. The space quoted for an installer does not always match the footprint after setup, so extra headroom is sensible. If your phone is close to full, removing unused files or apps first is the simplest way to avoid an installation that stops partway through.
Which version and date does this listing show?
This listing shows version 6.15.1, dated 2026-10-02. That is the exact build delivered here. Other builds are not described anywhere on this page, so if you are comparing it with another copy of the app, match the full version string rather than inferring anything from the date alone.
What is Invoice Simple for?
It is filed under the business category and its name reflects its purpose: carrying out invoicing work on a mobile device. The package com.aadhk.woinvoice is published by the developer of the same name. The listing does not include a detailed feature breakdown, screenshots or a changelog, so anything beyond the invoicing focus is not confirmed here.
Is a content rating shown for the app?
No. The content rating field for this listing is recorded as unknown, meaning no rating has been supplied. Anyone placing the app on a device shared with younger users should therefore rely on their own judgement, since the usual age-guidance signal is absent from this page.
