To develop a web-based application, accessible through a username and password.
The application is to calculate tax liabilities, based on an Excel spreadsheet that I have developed. Ideally, as an initial minimum viable product, I’d like the spreadsheet to be used to perform the calculations. Then, if successful, for these calculations to be programmed into the application instead. So initially, the idea is to have a web-based front end, and data entry form, which then sends the information to Excel for calculation, and the report to be a web-based PDF-looking report.
Customers need to be able to upload their company logo to their account, and for this to be shown on all reports produced.
