Customers & bookings

Add a customer

Create a customer record so it can be selected for quotes, bookings and contracts.

THE QUICK ANSWER

Open Customers and choose Add new customer. Enter the required customer name, then add contact and address details that your office needs. Select Create customer. DTE checks for an existing live customer with the same email or exact name first, so you can open that record or deliberately create a second one.

Before you start

You need access to Customers and permission to create customer records.

  • Have the customer's name and, where available, a contact email, telephone number and address.

Something not quite right?

Why can't I see Add new customer?

Ask an administrator to give you Customers access with permission to manage customer records.

Why does DTE show an existing customer?

It found a live customer with the same email address or exact name. Open it first to avoid splitting the customer's history.

Can I create two customers with the same name?

Yes, after the warning, when they really are separate customers. The warning is there to prevent accidental duplicates.
