Contacts

The address book of customers and vendors used everywhere else in ZenBooks - invoicing, voucher lines, and e-invoicing all pick a contact from this same list.

Customer vs. vendor

Each contact is a customer, a vendor, or both. Customers get an auto-assigned running customer number (used on invoices and in reference-number generation); the rest of the fields - business ID, VAT number, address, e-invoicing address/operator, payment terms - are the same regardless of type.

Where a contact is used

• Invoices - who a sales invoice bills, or a purchase is from.
• Voucher lines - optionally tagging a line with the counterparty, useful for later filtering/reporting.
• E-invoicing (Maventa/Apix, see Settings) - the e-invoice address/operator fields are what routes an outgoing invoice to the right recipient network.
