You can combine multiple products or components in a bundle. In erplain, they are called assemblies and kits. Just like creating a recipe, you can create a product that is made from other products (or components).
There are 2 types of bundles:
1. Assemblies - Products made of components or raw material.
The assembly works as a standalone product, it has its own stock level and its own pricing. Therefore, when you sell the assembly, you sell the stock of the assembly, not the stock of its components. You need to allocate the stock from the components to the assembly, this is done from the Transform assembly option.
2. Kits - A set of products grouped together.
The kit is a virtual product, its stock is a real time calculation based on the stock of its components. When you sell a Kit, you sell the stock of the components directly. The price of the kit is the sum of the price of its components, or you can define a set price for the kit (for each price level).
Where to start?
Whether it's kit or an assembly, it is necessary to create each component in erplain. Components are separate products, each with their own stock, price, SKU, etc. For information, you can buy or sell the components individually of the kit or assembly.
Assemblies
This type of bundle is just like linking multiple products together. The stock of the assembly is the result of a manual transformation of the components. Based on the components in stock, create the desired assembly quantities.
IMPORTANT:
- The price of an assembly is independent of the price of its components.
- The assembly is compatible with the use of purchase orders, entries, removals and stock movements.
- When selling an assembly, only the inventory of the assembly is updated.
- Assemblies can be used as components of other kits or assemblies
Creating an Assembly
To create an assembly, start by creating a new product (or editing an existing product) with its information, pricing and inventory. Products > + CREATE
1. Select product type, single product or with variants then "Assembly".
2. Then, select the products and quantity that will become the components of your new assembly. For example, a product called Table is made of 1 Table top, and 4 Legs (its components).
3. Transform bundle
Once you have created your bundle, you will need to allocate the components from your current inventory to 'create' a certain number of bundles.
In other words, you need to transfer the components' inventory to your new 'bundle' product (or finished product). In the example above, you will need 1 'Table top', and 4 'Legs' to make 1 'Table'. Your 'Table' inventory will increase by one, the Legs' inventory will decrease by 4 and the 'Table top' inventory will decrease by 1.
Select the Assembly to transform and choose the location and your quantity:
For example: if you type 5, it will create 5 'Table', remove 5x4 'Legs' and 5x1 'Table top'.
Erplain will suggest automatically the number of assemblies you can create based on the component's inventory but you can still create more bundles if necessary. The inventory of component will be negative, ready to be replenished.
Split an assembly
If you want to reverse this operation, you can split a bundle. Splitting the assembly "Table" will reduce the inventory of Tables and increase the inventory of table tops and legs in the selected location.
Assembly in a purchase order
The assembly is compatible with the use of purchase orders, after selecting your assembly you have the possibility to replace it with its components by clicking on the icon below :
Kits
This type of bundle will create a product that doesn't have its own inventory. The inventory is calculated in real time from its components. No transformation is required.
IMPORTANT:
- Kits are not compatible with the use of stock entries, stock removals or stock movements.
- Kits cannot be used as components of other kits or assemblies.
Creating a kit
To create a kit, go to Products > + CREATE:
1. Select product type, single product or with variants then "Kit".
2. Add the kit information, SKU, name, etc.
3. Select the products and quantity that will become the components of your 'kit' product.
Example: The kit 'Tennis kit' is made from 3 pair of socks and 1 pair of shoes. If you have 10 pairs of socks and 5 pairs of shoes, then your kit will have 3 on-hand.
Pricing for kits
You have 2 options for the pricing of your kits:
1- If you don't enter any price information in the kit, the price of the kit will be the sum of the price of its components (corresponding price level). You can also add a discount in the 'Kit discount rate' field. The discount applies on each component. If a kit with a discount of 20% and includes Product A with a price of $20 and Product B with a price of $40, the bundle price will be $48.
- Discount on product A: 20 x 0.8
- Discount on product B : 40 x 0.8
2- You can also define a set price for the kit (for each price level). In this case, the corresponding price will simply be used while creating a sale or a purchase.
IMPORTANT:
a) The discount will not be used if you define a price for the kit.
b) If you define a price for your kit, the prices and taxes of each component will be recalculated from the price of the kit. In some cases, the necessary rounding may cause small discrepancies between the kit tax amount and the sum of the component tax amounts
Stock level
Once the kit is created, you can view the component's inventory from the Stock level menu:
