I set up my own Ltd company last year offering consultancy / project management services in my specialist industry. Since Dec 2015 I have had a great 'contract' with a start up company which started as a day rate but then was negotiated to a fixed fee monthly basis with an agreed understanding of a min and max days work. This suited me fine as it covers months when I wanted to pair it right back either for family commitments or other projects that were short term.
It's also a great opportunity for networking / building my profile within the industry and so in my head I put some of the time investment down as business development for my future career.
I have ALWAYS done over the minimum and if I were billing at my usual rate would regularly be £500+ more than the monthly invoice.
I have really enjoyed the job and I am now a pretty integral part of the business who has considerable and very technical experience and knowledge of the company which no-one else has. I.e. I am not as replaceable as I was at the beginning.
I want to negotiate my position but don't know where to start as I've never done this before. Previously, in employment, I would wait for a sucessful 1 to 1 and then mention the chance of a salary review - or just went for promotions etc. when appropriate.
Should I put something very vague in writing and then ask for a meeting to discuss? Or set out a specific expectation of what I want on email and just wait for a negotiation which would probably take place on email? Or phone him??
We have a very relaxed and open relationship but I am aware that he is a client not a boss and that this might need different handling to how I am used to.
Any tips would be gratefully appreciated.
