Invoicing me?

If you’re a subcontractor requesting payment, I will need a proper invoice for my records. There are some guidelines and requirements below that will make sure the bookkeepers and tax authorities don’t get too worked up, but if you already have a good invoicing tool, your invoices probably comply with normal standards.

Please attach your invoice as a PDF to an email and send it to [email protected].

If you prefer to send your invoices by traditional mail, address them to:

Chris K N Consulting AS
c/o Chris Nordtømme
Saltboveien 25
1560 Larkollen
Norway

Chris K N Consulting’s VAT number is: NO 912 160 475 MVA

If you have any questions, please don’t hesitate to ask.

Requirements

The invoice should ideally be a separate document in PDF format (so it can’t be edited), and contain the following information:

Name and address of the seller. Who is requesting payment (normally you or your company), and how can someone get in touch with you with questions?

Name and address of the buyer. That would be my company:

Chris K N Consulting AS
Saltboveien 25
1560 Larkollen, Norway
[email protected]

Invoice date. Normally the date on which the invoice is created and sent. It is preferable — but not required — that you send the invoice the same month the work was delivered, or at the beginning of the following month. Please don’t wait too long.

Due date. The date the invoice should be paid. Please allow at least two weeks.

Payment details. Bank account information, including IBAN/SWIFT for international transfers.

  • If you wish to be paid through PayPal (despite the fees), include the correct email address to use.
  • I recommend Wise instead — it’s fast and inexpensive for international payments.
  • Some invoicing tools also integrate with Stripe for easy credit card payments.

Line items with:

  • A brief description of the work — for each item, a few words explaining what we’re paying for, and when and where it was delivered. Please specify the project or client. Example: Design for Project X. Remote work. Delivered Jan. 1, 2025.
  • Amount and unit price. Example: XX hours at $YY per hour.
  • Any amounts already paid (deposits, advances, partial payments).
  • The total amount due.

Depending on the situation, you may also need to include:

  • An invoice number. A unique, sequential ID that can’t easily be manipulated is required by law for Norwegian companies, but rules vary by country. If in doubt, include one.
  • Taxes. VAT, sales tax, or other applicable fees should be clearly itemized.
  • Discounts or deductions. Any discounts, rebates, or advances to be subtracted from the total should be specified.

If your invoicing application doesn’t have all the necessary fields, there is usually a notes field where you can enter additional information.

Please send your finished invoice to [email protected].

Tools

If you don’t already have a good system for creating invoices, there are many options available:

  • Free one-off invoice generators — Wise and Stripe both have built-in invoice tools. These are easiest if you just need to send a quick invoice.
  • Dedicated invoicing apps — Invoicely and Zervant are both Freemium. Better suited if you’ll be sending a few invoices regularly but don’t need full accounting features.
  • Full accounting software — FreshBooks (paid, with free trial) if you also need bookkeeping and accounting.
