Usually when we add a new supplier, we don’t know all their info (VAT No, exact company name etc).

We suggest using a “unique supplier id” for every supplier to avoid duplicate entries.
You can add a new supplier using his phone number (or something else) as “unique supplier id”, in case VAT No/Tax Id is not known.

Other information you can insert are: Supplier Name, Vocation, Expense Type, VAT No/Tax Id, Form of payment, address, etc.

Although it is not required, it is recommended to enter the “Form of Payment” for each supplier. That is going to be very useful, when you create a contract or a purchase order with the particular supplier.

In order to maintain GDPR compliance you can import a signed GDPR agreement (in pdf) with any supplier and insert the Expiration Date in the designated field. Then checking in GDPR column, you can find out easily which agreements are expiring soon, so you can either renew them or delete them from you database.
