On a good year I manage about 10% of my flying for business in our group Jodel. However, I do have a plan B (and C). Plan B is to hire an airways-equiped a/c if the weather is too bad for VFR, and plan C is to drive / use scheduled service if icing, etc. is going to be a problem. (No de-ice equiped aircraft available for hire locally).
Sometimes, the trip is not date-critical, and I can therefore select a day with suitable weather for the Jodel.
I can thoroughly recommend flying yourself on business. The pleasure you get from claiming the vat back on the AVGAS and the landing fees is out of all proportion to the sums involved.
