This forum was designed to help us all navigate this new territory. IOSS has been a headache to say the least. It is new to many, if not all of us.
Personally I have found the forum helpful and Damon and his team from Crossborderit have always answered any emails I have sent across.
We too are only a small UK merchant with a basic shopify plan. We don’t do many sales to the EU but we have had to conform to the new IOSS rules as we wanted POS transparency for our EU customers.
I am sure that as we all become accustomed to the IOSS way of doing things there will be more options available to suit our pocket and EU shipping quantity at some point in the future. Until then I am more than happy to stay with Crossborderit. We all have costs and the IOSS has increased our costs as a small business.
We just need to get on with it, see how it goes and if it doesn’t work for you or (me) then we do some research. Until then can we continue to support each other and I appreciate this forum because I have learned alot, so thank you.
