My mother’s sister is past 80 and still running her own company. Naturally, I do her IT-support since -95 when she realised that it was important to utilise a computer for her business.
The other day I was installing an invoice program for her. She has been using an Excel template, designed by my wife. But new regulations on VAT made her go for specialised software. She choose a well established product. It turned into a lesson for me.
