# Customer Details
Collection and Delivery services use the **Customer Database** for **faster customer lookup**.
## Existing Customers
When entering the **phone number**, it provides you **suggestions** based on customer information currently in the database. The more you type, the narrower the search results are.
For Delivery orders, as you enter the phone number, it also shows you address suggestions that are associated with the customers. Clicking on the address **automatically fills in the fields**.
If an existing customer wants to use a **new address**, you can select the **customer's name and phone number**, then **add the new address** in the address tab.
## New Customers
If information is not in the customer database yet, you can **enter the details manually**. You can click between the **Phone**, **Name**, and **Address** tabs at the top.
After entering the customer details, click on **Save** on the upper right-hand corner.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.bossithq.com/pos/order-creation/customer-details.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
