Customers
Overview
Customers represent the clients or companies that receive invoices in WBudget Invoice.
Each customer record stores identification, contact and address information used when issuing and sending invoices.
Customers can include multiple contact emails, allowing invoices to be sent to different recipients within the same organisation.
What is this for?
Customers are used to:
- Identify who the invoice is issued to
- Store contact and address details
- Speed up invoice creation
- Send invoices to multiple recipients when needed
- Maintain a clear customer database for reporting and history
Every invoice must be linked to a registered customer.
Customers table overview
The Customers screen displays all registered customers in a table view, including:
- Customer name
- Identification number
- Address
- Main contact name
- Telephone
- Actions
You can search customers, review their details and manage records from this screen.
