Distance Based Shipping

Hi,

I am running into a few headaches with the limited shipping options available with Squarespace for small businesses. I'm in the UK making large heavy items and only offer local delivery fulfilled by myself. At the moment the only way I can charge correctly for this is having a large list of "Flat Rate" shipping options for each of the post codes I service, and relying on the customer to pick the correct one.

Are there any plans or 3rd part options for distance based shipping like one the WooCommerce platform. I feel this would be a massive bonus feature to have for so many small businesses who operate like myself, rather than having to come up with clunky workarounds that leave lots of room for customer error.

Many thanks, Benedict.
