With any new business venture ( Start Up) the initial phase is crucial. A lot of thought has to be given to how you foresee the business developing and what will be your future requirements. Obviously somethings can never be foreseen Covid19 !!
Here are some of points to consider
Do not tie yourself up in long term office / property leases , keep flexibility to be able to relocate.
Depending on work duties Virtual Office can be ideal launching pads in the first phase.
Number of Employees
Do not offer long term permanent contracts to new employees , keep it on temporary basis until you have assessed the type of skills / personnel requirements.
Accounting / Bookkeeping
Keep your options open, there are a lot of cloud based softwares available nowadays and there are specialised online bookkeeping services who can guide you rather than traditional office based accountants.
Using non geographic numbers eg 0303 gives you flexibility to take your number with you or even to answer incoming calls on your mobile.
The golden rule is always to keep your options open in the early stages. In my experience the original concept of Start Ups and the actual business realities usually end up with a different end product.
