About WeFact

WeFact is an invoicing and accounting software package that helps businesses easily and efficiently generate invoices, manage customer data, and track financial transactions. It is designed to streamline the invoicing process and simplify administrative tasks.

WeFact offers functionalities such as creating and sending professional invoices, managing debtors and creditors, generating reports, and tracking payments. It is a versatile solution suitable for both small businesses and independent professionals.

When you record hours on this activity and create an invoice, they will automatically have the correct category and VAT percentage.

Import Customers
