Set-up
Delivery checkout ID is always the highest level. You can build your entire structure from one ID. If you have more than one webshop, operate on different markets with different carriers, support several countries, languages and currencies, it's a good idea to consider more than one delivery checkout.
A delivery option is either a service, or a container for services, for example, agent delivery services.
Sublevel is optional and is used to group services
Tip
A general recommendation is not to display too many overlapping delivery options.
Addons, carrier specific or custom addons, can be added for services on delivery option level or sublevel.
Note
For most delivery options, services, prices and addons it's possible to enter appliance conditions.
You can also use extended conditions to dynamically modify certain text fields.
Before creating your delivery checkout it's recommended to explore delivery conditions further.
So, the set-up can be either flat or hierarchical.
