Hi sally you are fortunate to have a good NZ base. To expand offshore I would suggest you focus on just the segment of the market where your product is likely to give customers the best payback. A narrow focus on just one type of customer as a first step and then expanding later is usually a more successful strategy than casting the net widely.
If your target customers see a real need that’s the best approach. My experience also is that when times are difficult products that can increase revenue are more likely to be adopted than those that reduce cost so if you can demonstrate a revenue increase for a defined set of customers that’s where I would focus good luck and well done with what you have achieved to date.
