Linked products
Link accessories, insurance, services, spare parts, alternatives or auto-added products to a product.
Flow Retail lets you link other products to a product — an accessory, an insurance, a service, a spare part — so the right extras are offered at the right moment instead of being remembered.
With the auto-add type you can go further and have a product added to the order automatically. That is how a bottle deposit, an environmental fee or any other per-product charge gets onto the order without anyone thinking about it.
How to add linked products
Open the product in Backoffice and go to the Linked products tab. Add as many linked products as you need, choosing a type for each.
The seven link types
Accessory
Offered when the product is added to an order. Any number can be added. The accessory stays on the order even if the original product is removed.
Insurance
Offered when the product is added to an order. Only one insurance can be selected, and it is removed automatically if the original product is removed.
Service
Anything performed alongside the product — assembly, installation, setup.
Freight service
A shipping or delivery product linked to what is being shipped.
Spare part
A part that can be used to repair the product. Mainly used by the Service system.
Alternative
What to offer instead when the main product is not available.
Auto-add
Added to the order automatically when the original product is, and cannot be removed without removing the main product.
What happens when the original product is removed
The types differ in whether the linked line survives, and this is where intuition usually fails:
Accessory
The accessory stays
Insurance
The insurance goes
Auto-add
The auto-added product goes
Accessories staying behind is deliberate — a customer who changes their mind about a jacket may well still want the bag. But it does mean an order can keep an accessory whose parent is gone, so it is worth a glance before settling.
An auto-added product cannot simply be deleted from the order on its own. Removing the product that triggered it is the way to remove it.
On the order
Each of these relationships becomes a pair of linked order lines, one type on each side — an insurance line points at what it insures, and that line points back. See Order lines.
Limitations
Only one insurance product can apply to a product on an order.
Spare parts are for the Service system; they are not offered during a normal sale.
Alternatives are a suggestion for staff, not an automatic substitution.
