Create a contact
Contacts are the foundation of SNDQ. Every co-owner, supplier, and tenant is a contact. Accurate contact data is essential for:
- Broadcasts & correspondence — emails, letters, and meeting invitations are sent based on the contact's email and correspondence preference
- Payment matching — bank payments are matched to owners and suppliers via their IBAN
- Invoicing — supplier contacts are linked to purchase invoices
- Meetings — co-owners receive invitations and can vote based on their contact record

WARNING
The IBAN is used to automatically match incoming bank payments to owners and outgoing payments to suppliers. Without a correct IBAN:
- Owner payments will not be recognised during batch reconciliation
- Supplier payments will not be linked to purchase invoices
- Internal transfers between accounts won't be detected
Why each field matters
| Field | Impact |
|---|---|
| No email → no email broadcasts, only physical letters. Meeting invitations, provision letters, and reports won't be delivered digitally. | |
| Correspondence preference | Determines if the contact receives emails or physical letters for all correspondence. |
| Preferred language | All broadcasts and generated documents are sent in this language. |
| IBAN | No IBAN → payments from/to this contact cannot be automatically matched. Manual assignment required. |
| Address | Required for physical letters. Also used in meeting attendance lists and official documents. |
Good to know
- One contact, multiple roles — a contact can be both an owner and a supplier. Use sub-contacts for complex structures.
- Multiple IBANs — a contact can have multiple bank account numbers. All IBANs are used for payment matching.
- Multiple emails/phones — add as many contact methods as needed.
- Archived contacts — contacts can be archived (not deleted) when no longer active. Archived contacts are hidden from the active list.
- Sub-contacts — for companies with multiple contact persons, add sub-contacts under the main business contact.
- Linked units — the Linked column shows how many building units are associated with this contact (via ownership or tenancy).
