Locksmith

We use Locksmith to provide a closed staff-only shop for our team. We have implemented a simple lock that allows only users with pre created Accounts tagged with access to connect. In addition it also limits by geo-location - we only want staff in one country to connect.

If you READ the licencing policy correctly you will see that they have a fair policy. In our case we have a tiny number of customers, but need the bigger Shopify plan as we have a pool of people who sometimes look after Shopify. So we have been able to mix and match the pricing as we need. If we were running a higher volume store, we would accept paying more as the whole Shopify ecosystem is waaaaaaay cheaper than building a custom site from scratch!
