Dynamics 365 Field Service uses the Dynamics 365 product catalogue and price lists for on-site service. Field technicians can use the same products for work orders that salespeople use for opportunities, quotes, and orders.

With the product entity, you can create products and services to add to work orders.

1. Product is an item a field technician may record while completing a work order for which the client may be billed. Products can be physical items, like a battery or a part, or maybe non-physical components, like an oil change or an estimate. Both physical and non-physical products are measured and sold in quantity of units. Many physical items are tracked as inventory. Non-physical items won’t be tracked as inventory.

2. Service is work that a field technician performs and may bill the client for. Service is measured in time duration.

If a field technician uses a product or performs a service while on the job, they can then enter the work into the Field Service Mobile App. Used products and performed services can be invoiced to customers based on the applicable price list or entitlement. Used products can be deducted from inventory levels either in the Field Service inventory module, Dynamics 365 Finance & Operations, or an external ERP system.
