Best Practices for Proposal Creation

A professional proposal is more than just a price list – it's your business card and often the first step to a successful business relationship. This guide shows you how to create compelling proposals that build trust and win contracts.

What Belongs in a Professional Proposal?

A complete freelancer proposal contains the following components:

Sender Information (Letterhead)

• Full name or company name
• Legal form (if applicable: GbR, UG, GmbH)
• Business address with street, postal code, and city
• Contact details: phone, email
• If registered: court of registration and commercial register number

Recipient Information

• Complete company name and address of the customer
• Name of the contact person

Formal Details

• Proposal date and proposal number
• Validity period of the proposal
• Subject line clearly marked "Proposal"

Content Components

• Detailed service description
• Quantities (hours, days, units)
• Unit prices and total prices (net)
• VAT (19%, 7%, or small business exemption notice)
• Gross total amount
• Delivery/service period
• Payment terms

Recommended Proposal Structure

Mandatory Information by Legal Form

Sole Proprietor (not in commercial register)

• First and last name
• Serviceable business address

GbR / eGbR (Civil Law Partnership)

• Names of all partners
• Legal form suffix "GbR" or "eGbR"
• Business address

GmbH / UG (Limited Liability Company)

• Complete company name with legal form suffix
• Registered office
• Court of registration and HRB number
• All managing directors (first and last name)

Proposal vs. Cost Estimate

Many freelancers use the terms interchangeably – legally, however, there are important differences:

When to Use a Proposal?

• For fixed prices
• For standard services with known scope
• When quick contract conclusion is desired

When to Use a Cost Estimate?

• For complex projects with unclear scope
• For uncertain price calculations
• When adjustments are likely

Important: For significant overruns (>20%) of the cost estimate, there is an immediate notification obligation under § 650 para. 2 BGB – the customer then has an extraordinary right of termination.

Avoiding Common Mistakes

1. Incomplete Service Description

Problem: Vague wording leads to misunderstandings and renegotiations.

Solution: Describe each service as specifically as possible. Define scope, deliverables, and exclusions.

2. Missing Validity Period

Problem: Without a deadline, you remain bound to your proposal forever.

Solution: Set a clear validity period (e.g., 14 or 30 days).

3. Unclear Payment Terms

Problem: The customer doesn't know when and how to pay.

Solution: Define payment deadline (e.g., 14 days after invoicing), accepted payment methods, and deposit arrangements if applicable.

4. Missing Call-to-Action

Problem: The customer doesn't know what to do next.

Solution: Close with a clear call to action: "For questions, reach me at... To place the order, please sign the attached copy."

5. No Personalization

Problem: Copy-paste proposals seem impersonal and are often ignored.

Solution: Reference the specific inquiry and the customer's specific needs.
