Isen workshop: adventures in batch production (or not...)

Yup.

Shopify is good, but the fees can add up so you need to make sure that you have a regular shop margin, etc.

If I have criticisms of Shopify it is that it's too simple on complex shipping costs, and that sometimes what I feel is basic functionality requires an app to get the functionality that you want.

But... it is easy to use, it is easy to configure product, the customer database and orders are easy to manage and process, the experience for the customer is good, the payment options are good, the risk mitigation of fraud is good... and considering it's a basic fee structure it's easy to get to grips with too.

I do recommend it highly. It's only when you need to go really bespoke on things that Shopify isn't appropriate (when you need to set up a shop like the Rapha one).

I agree with Velocio that Shopify is great. But @Señor_Bear is right too. If your main product is essentially a set deposit and then a variable final amount then the transaction fee that Shopify take will be a margin killer. Shopify overkill unless you start selling 20 other SKUs as well.

I’d recommend using https://craftcms.com/ or something similar and a simple payments/order form with https://stripe.com/gb

Bank transfers set up a barrier and will cause a lot queries that won't convert to actual orders.

Stripe take 1.4% of your transaction (plus 20p). Whatever Shopify tier you choose Shopify take more % as well as a monthly fee.
