Give some thought to regulation. All products sold in Europe must be CE marked and comply with the relevant EU Directives and legislation. What applies to your product? Does it need independent certification? Who will do it and what will it cost?
Insure against risk. Public Product Liability Insurance is a legal requirement. Again, discover the cost and build it into your pricing structure. Other insurances for consideration would be Goods in Transit, Commercial Legal Expenses, Professional Indemnity, Annual Business Travel, and most importantly Intellectual Property Insurance.
IP insurance can help cover your legal costs should you need to take enforcement action. It can also act as a deterrent to potential infringers.
Consider Point of Sale- Packaging, Method of Distribution- Packaging, Method of Distribution, etc. Who will sell the product; retailers, wholesalers, distributors or agents? In which markets will you operate? What sales literature is needed, will it need to be translated into different languages.
Essentially the message is “be prepared” and question at every stage. Whoever you see to develop the idea will challenge your assumptions and projections vigorously until they are satisfied it is worth investing time, money and effort in going forward. This investment in doing your homework can only pay dividends because you will not be presenting a half baked idea destined for failure, you will be well on the road to success.
We hope this is helpful and wish you good fortune with your venture.
