A client can have multiple locations and one billing address.
You can manage and modify those.
Viewing client locations
Go to clients and click on your client's name
Tip: You can use the search box to find a specific client.
In the clients page, under the properties tab you can see a list of locations for this client, edit them or add new ones.
Adding a job for a service location
If your client has more then one location, when you click actions and then add job, a list of available locations will pop up.
Or you can just choose, create new location to enter a job for this client using a new address.
On your jobs and invoices
When you create an invoice within a job, that invoice will show the billing address and the service address for this client.
Tip: you can customize what is shown on any document
Invoices/ Estimates not linked to a job
Invoices and estimates not linked with a job will only show the clients billing address since no service address was specified.
