The assignment was not an accident. Before being redeployed to Benin brewery, I had been involved in "validating" the numerous complex formulas in the custom Lotus 1θι spreadsheet application during its development. The author _ Richard Chambers _ was at the time in charge(as Training Coordinator) of training new entrants, and upon discovering my keen interest in learning, often gave me his laptop to "proof" formulas, links etc. It was he who had told his counterpart in Benin brewery(Joe Sheehy) that I could help out with a problem they were having using the application. And I did resolve the problem _ resulting in my subsequently becoming responsible for the reports collation using the application.
The savings _ from using your "in house" expertise _ in terms of money and man_hours alone, will quickly justify the investment you make in "developing the needed skills" _ especially, when you compare what you spend with the cost of purchasing a commercial software application _ or even engaging the services of an Excel VB developer.
I believe the foregoing are compelling justifications for choosing Excel Visual Basic over Visual Basic.
For the purpose of creating custom financial and business management solutions that solve your identified problems, and give you control/ownership, without burning a hole in your pocket, Excel VB offers an amazing variety of possibilities, in the hands of an adequately skilled user.
