How to write a professional business letter

At a time when most things are handled by email and messaging tools, writing a formal letter can feel old-fashioned. But that's precisely why a physical letter carries more weight. It signals that the sender has taken the time and care to address the matter properly, which is especially valuable for:

• Formal offers and quotes to new customers
• Termination of contracts, employment or subscriptions
• Complaints and claims that require documentation
• Introduction letters to new business partners
• Official notices to boards, shareholders or members

In many of these situations, a physical document is also required - one that can be kept, archived or used as evidence. An email can be deleted or end up in a spam folder, but a posted letter has a clear sender, a date, and a traceability that creates confidence for both parties.

A good business letter template is built on a clear structure that the recipient recognises and can navigate quickly. Here are the elements that should be included, in the right order.

1. Sender details

At the top, usually to the right or left depending on the company's visual identity, state:

• The name of the company or individual
• Address, postcode and city
• Phone number and email address
• Company registration number if relevant to the matter

2. Recipient details and date

Below the sender details, write the recipient's name, any title, company and address. The date is usually placed to the right, above or below the recipient's details. This is especially important in letters concerning contracts or terminations, where the date often determines which notice period applies.

3. Subject line

A short line in bold that summarises the purpose of the letter, for example "Termination of Supplier Agreement No. 4521" or "Quote for Office Cleaning 2025". The subject line lets the recipient immediately understand what the letter is about, even before they start reading.

4. Salutation

Adapt the greeting to your relationship with the recipient. "Dear Mr Andersson" often feels overly formal today, while "Hi [name]" works in most business contexts. If you don't know the recipient's name, "To the Purchasing Manager" or an equivalent works well.

5. Body text in three parts

The content itself should always follow a logical structure:

• Introduction: Why are you writing, and in what context?
• Main section: What do you want to convey, request or inform about? Be concrete and avoid padding.
• Conclusion: What do you expect to happen next? Should the recipient reply, sign, pay, or take some other action?

6. Closing phrase and signature

End with a polite phrase such as "Kind regards" followed by name, title and, where applicable, a signature. In physical letters, a handwritten signature adds further weight and a personal touch - something that's completely lost in a regular email.

Many people make business letters too formal and stiff, which in the worst case can come across as distant or even unfriendly. Instead, aim for a tone that is:

• Clear – avoid convoluted phrasing and legal jargon unless necessary
• Concrete – say what you mean without unnecessary circumlocution
• Respectful – even in a complaint or termination letter, the tone can be factual without being cold

A common mistake is mixing too much emotion into a business letter that actually calls for a factual approach, or conversely, making a relationship-building letter far too bureaucratic. Always read the letter through one more time and ask yourself: would I want to receive this letter myself?

Although the basic structure is the same, the content varies depending on purpose.

Quote letters

Here, the focus is on clarity regarding price, delivery time and terms. Be specific with figures and dates so the recipient doesn't need to come back with follow-up questions.

Termination letters

Always state the contract number, termination date and desired end date. A physical letter often serves as legal proof that the termination was made on time, which makes it particularly important to keep a copy and to actually post the letter rather than just email it.

Complaint letters

Describe the problem concretely, state the order number or reference, and be clear about the resolution you want - a refund, a replacement item, or a credit.

Introduction letters

Briefly introduce yourself or your company, explain why you're contacting this particular recipient, and end with a clear call to action for the next step, such as a meeting or phone call.

Once you've finished writing the letter, there's still the practical matter of getting it to the recipient in a way that feels just as professional as the content. This is where Posta Brev can make all the difference. Instead of printing, enveloping, stamping and going to the postbox yourself, you write the letter directly in our service at /skapa-brev, and we handle the rest - printing, enveloping and delivery via PostNord.

This is especially valuable for companies that send business letters regularly but lack the time, printer or envelopes at the office. You skip the queue at the post office and can instead focus on the content of the letter. If you'd like to see what it costs depending on the number of pages and delivery method, you'll find a clear overview at /priser.

The service works just as well for a single letter as for recurring mailings, and you can use the same process whether it's a formal business letter, a thank-you letter to a business partner after a completed project, or a congratulations letter to a colleague who's retiring. If the letter needs to go abroad, for example to an international supplier, you can read more about how that works at /skicka-brev-utomlands.

Writing a business letter digitally doesn't mean it has to feel impersonal. Many people choose to supplement with a digital stamp for less urgent mailings, which you can read more about at /digitalt-frimarke. Whichever option you choose, the most important thing is that the letter actually arrives on time and in professional condition - something a service like /skicka-brev simplifies considerably compared to handling everything manually.

A business letter doesn't need to be complicated to write, but it does require structure, clarity and a tone suited to the context. By following a fixed template with sender details, a subject line, a logically structured body and a clear conclusion, you create letters that feel professional and easy to understand. And once the content is ready, you don't need to deal with printing and postage yourself - write the letter at /skapa-brev and let Posta Brev take care of the rest.
