business model, monthly subscritption - Excel spreadsheet RRS feed

  • Question

  • Hello guys, 

    I'm working to create a solution to a company as an independent consultant. I'll be paid by result as soon I deliver the product. The product is a set of spreadsheets to manage data, reports, and KPI's. 

    Is it possible to create a way to auto-lock (and an unlock key) the spreadsheets after a pre-determined period forcing the company to pay the correct amount monthly. It's like a monthly subscription and this is beyond my expertise. 

    Thank you in advance.
