While the kit system is designed primarily for just-in-time (JIT) kit assembly during picking and fulfillment, there are ways to manage tracking preconfigured kits in SKULabs as well.
The key objectives to consider when deciding how to manage preconfigured kits are:
Tracking distinct on-hand stock of preconfigured kits and the individual (unbundled) items used to assemble just-in-time kits. i.e. How many preconfigured kits do you have? How many JIT kits can you make based on the available stock of component-items?
Whether your team will break apart preconfigured kits to fulfill orders for individual items or other just-in-time kits that could share a component item.
Having a straightforward link between a listing and preconfigured kit while avoiding overselling.
Simple picking and deduction.
How to handle pre-configured kits
The cleanest and simplest recommendation is to treat preconfigured kits as distinct individual items:
Create an item SKU to represent complete units of preconfigured kits.
Link the existing listing on your sales channel to this new item SKU.
When building preconfigured kits, deduct stock from the individual component-items used to preconfigure a kit. Then, add stock to the item SKU you've just created to represent preconfigured kits.
Your sales channel will reflect the available stock quantity of the pre-configured kits you've added to SKULabs and orders will appear as a single line item of the complete kit.
How to advertise stock for both pre-configured kit quantities and just-in-time kit quantities on your sales channel.
This requires a workaround method using using two listings, one linked to each fulfillment version of the kit.
Follow the same steps as above, but create a new listing on your sales channel to represent the pre-configured stock levels. This essentially means you would have multiple listings for the same kit.
What if you don't want to have more than one listing for a kit?
While this is possible, it is not recommended because it comes with tradeoffs such as under-advertising stock, overselling stock or introduces fulfillment complexities.
