Here is a list of Companies and services we use that we highly recommend for anyone running a business. (Some may only be applicable to UK businesses)
Banking
Revolut (Opens in a new window)
We use it for all incoming payments
Online store
Shopify (Opens in a new window)
We use Shopify to host our site. Although we have used other platforms in the past, we now only use Shopify and find it the easiest to use.
