Me and my brother have a limited company, with 1 angel investor. We sell software we have written ourselves, mainly to individuals but we will be looking at educational institutions soon. Our refund request rate is around half a percent if that makes any difference.
The software doesn't handle money in any way, and it's not a service (it's a game development program).
We run it currently from home, but eventually want offices but that will probably be 8-12 months away. The registered business address is a forwarding address.
How important is business insurance for us?
