Customers
Add and manage customers in EenFactuurMaken.nl. Businesses and individuals, addresses, VAT numbers, per-customer defaults, archiving and the Free plan limit.
You manage your customers under Customers. You can also create a customer straight from an invoice: type the name and choose New customer.
Business or individual
First choose the Customer type:
- Business: name, address and (usually) a KvK and VAT number. The strictest invoice requirements apply to business customers.
- Individual: an address is recommended but not required. For individuals we state the statutory collection costs as an amount in the final notice.
Details
| Field | Explanation |
|---|---|
| Name / Company name | Required. Printed on the invoice. |
| Contact person | Printed as "Attn." on the invoice and used in the greeting of emails. |
| Invoice email | We send invoices and reminders to this address. |
| Cc | Extra addresses, separated by a comma, for example the accounts department. |
| Address, postcode, city, country | Required for business customers. The country helps decide which VAT treatment we suggest. |
| KvK number | Optional. Useful for the e-invoice. |
| VAT number | Required for reverse charge and EU customers. Check it with Check in VIES. |
| Peppol ID | Your customer's e-invoicing address, for example 0106:12345678. |
| Internal notes | Only for you; not printed on the invoice. |
Defaults for this customer
You can override your own defaults per customer. Leave a field on Your default to use your own setting.
- VAT treatment: for example always VAT reverse charged for a contractor.
- Type of supply: goods or services (matters for EU and foreign customers).
- Payment term: for example 30 days.
- Invoice language: Dutch, English, German or French.
- Layout for this customer (Pro): one of your own templates.
These defaults apply to new invoices. Existing drafts don't change.
Customer overview
Open a customer to see their details, the outstanding amount and all their invoices.
Deleting and archiving
If you delete a customer who has no invoices yet, they're gone. If they do have invoices, we archive them instead: they disappear from your list and from the picker in the editor, but your invoices stay intact. You'll find archived customers under Archive, and Restore brings them back.
Free plan limit
On the Free plan you can have up to 25 active customers. Archived customers don't count. Over the limit? Archive customers or upgrade to Pro (unlimited). Through the API you then get 402 plan_limit_reached.
