Does anyone know where to get sales forecasts for a fabric store?

Firstly people tend not to put sales forecasts in the public domain. So instead it seems you are looking for historic data with which to use as a basis for your own estimates. However there is a significant flaw in this approach in that the sales data is de-contextualized so you have no sense as to the underlying factors or the narrative behind the data i.e. perhaps the store is in a prime retail location on a high street where there is a lot of passing traffic and high demand for the fabric. You need to work with your partner to create a range from scratch. Are you already selling on etsy or eBay or equivalents? This can help you assess demand. You can also search the Oxxford reports as listed on BPlans as there may be a report from a similar industry that you can peruse for clues to the likely demand ranges you could expect. Alan
