Web App Time-tracking for accountancy firms: Testing & Evaluation -- 2

I require an experienced accountant to conduct comprehensive testing and evaluation on my time-tracking web application's features for accountants and managers. The features I want tested include Overall usability, Users Onboarding, Company Settings and Industry-Specific Reports.

Here are some of the specific testing cases I need explored:
- ability to navigate through the platform effortlessly
- smooth performance across different devices (for landing page only) and browsers (for the whole app); responsive design for various screen sizes
- clear and concise labeling of buttons, menus, and features
- simple and straightforward registration and onboarding process for user and company
- user invitation features
- management of user accounts, including adding, deleting, and modifying users
- сonfiguration options for company-specific settings
- pre-defined report types tailored to the accounting industry
- customization options to meet varying needs
- analytics and insights relevant to the accounting industry
- visualizations that are easy to interpret for users
- Google Chrome extension functionality, performance and usability

The ideal candidate for this task should have:
- Profound experience in Accountancy, particularly as a user of accounting software Xero and/or Quickbooks web applications
- Xero and/or Quickbooks active subscription, ideally - ongoing client practice in these
- Google Chrome web browser

The aim is to form a deeper understanding of user needs, identify potential glitches and areas of improvement to enhance user experience and app functionality.

I expect one to commit 9 hours into the project. The probable itemization would be:
1 hour for understanding the task and the setup;
3-5 hours of mocking work in accounting software,
3-5 hours of browsing the app account and writing the testing report.
The overall budget for one tester would be around $90.
