I am in a partnership and it works fine 100% no probs ever, well i threw my dummy out once as i did 1 very messy upstairs window when my mate was in the van having a tea! We have been in a partnership for 3 years, and infact we have even let a friend of mine buy in and now we are 3 partners, 2 vans and 1 other employee!
A few things to consider:-
decision making - What are you going to do if you cant agree???
Sounds silly but we have had this discussion originally as a 2 man team and we decided the only way was to flick a coin, sounds stupid but how do you decide who knocks on awkward doors or who has to chase monies owed up etc etc, not major decisions but trivial day to day stuff
Buying in
We agreed an initial amount and i bought into the round from day 1, you want to be singing from the same hymn sheet from the start, if he has financial investment he will give 110% all the time like you!
Partnership agreement
We have done this to cover our selves, even silly stuff is on it but get it out in the open from day 1, not 3 months down the line. Even silly stuff like days off, working hours, who looks after the books, how much £ if one partner wants out, etc etc
It sounds trivial but we didn’t want to have a falling out about anything so have it all in black and white signed by all 3 of us.
Personally for us it was the best thing we could have done, going to a 3 partnership team means we now have 2 vans and the employee is always “looked after” by one of us :-) Plus all the costs are now 1/3rd and yes profits are also 1/3rd but we are now earning more for less days work as we can get round all our customers on time, we have gone from over 20 days to 12/13 days work a month, leaving loads more room for growth!
So I say if you can have an honest discussion about where you want the business to go and can get it all agreed go for it!
