The whole process can take around 6 months (and generally a minimum of 3 months) so be prepared to be fully committed to the transaction for that time frame. This can itself be very challenging as you will also be doing your normal day job running the business and keeping it on track.
As soon as the deal goes through you should firstly advise your staff and reassure them of what the future holds under your ownership. You should then inform your suppliers and customers of the change in ownership and seek opportunities to get some positive PR.
Your ongoing task is to ensure that your planned changes are implemented and followed through to ensure funding constraints are met and the business sets off on its new course successfully.
