Clauses That Should Be Included in a Software Agreement: A Complete Guide

Why is a Software Contract So Important?

In software development projects, the contract is the fundamental document that defines all expectations and responsibilities between the parties. In my 25 years of professional life, I've observed that most projects started without a contract end in problems. It's common for one party to think something has been done that the other party didn't understand at all. In this article, I'll focus on the clauses that absolutely must be included in a software contract.

This information is particularly critical for business owners, agencies, and software developers working in Alanya, Antalya, and the Mediterranean region. This is because many parties with varying skill levels work independently, and without written agreements, disagreements become inevitable.

1. Party Identification and Contact Information

At the beginning of the contract, the customer and the service provider must be clearly identified as parties . Simply stating "Mubin" or "Yazılım A.Ş." is not sufficient. The full trade name, tax number, headquarters address, and the name and surname of the responsible person must be specified.

In addition, the email addresses, phone numbers, and method of communication (email, social media, WhatsApp, etc.) for all project-related notifications should be clearly agreed upon.

2. Project Scope and Deliveries

This section defines the project scope down to the finest detail . It should answer the following questions:

• What will the software do, and what features will it include?
• Which platforms (web, mobile iOS, Android) will the development be for?
• What will the database, interface, and integrations be like?
• Will the page designs be provided as an addendum to the contract?
• Who is responsible for testing and quality control?

Vague statements render this requirement meaningless. Saying "a nice website" doesn't mean "an e-commerce site that sells products, has payment system integration, is mobile-friendly, and has a membership system." It must be concrete and measurable.

3. Code Ownership and Intellectual Property Rights

Code ownership is one of the most contentious clauses in software contracts. Who will own the source code when the project is finished? The client, the developer, or each owning their own portion?

I apply this rule when I'm working:

• For work paid for by the client, the code belongs to the client. The client can sell the source code to whomever they want, show it to another programmer, or have it modified.
• For a project that has been paid for, the programmer cannot use the code for another client.
• If general libraries (frameworks, plugins, etc.) have been developed, their ownership should be clearly defined or clarified with professional agencies such as Alanya IT Services .

Rights such as copyright, patent, and trademark should also be detailed.

4. Payment Terms and Pricing

The type of payment, its duration, whether it will be paid in advance or later, and what to do in case of delay are included in this clause:

• What is the total project cost in Turkish Lira/USD?
• How will the payment be divided? (e.g., 30% upfront, 40% upon design approval, 30% upon delivery)
• When should payment be made? (e.g., within 15 days of the invoice date)
• Are there interest or penalties for late payments?
• What is the payment method? (Bank transfer, cash, check, etc.)
• What will the unit price be for hourly/daily part-time jobs?

This section is the biggest source of disagreements. When it is unclear, discussions based on bank documents can drag on for months.

5. Timeline and Delivery Date

If the project's start and end dates become uncertain, the client and developer will share photos each month. If delays occur, the duration of the delay, the reason for the delay, and the method of compensation (discount, additional services, etc.) should be defined in the contract.

In addition, intermediate milestones should also be specified:

• Design mockup: X history
• Technical infrastructure is ready: Date Y
• Function testing phase: Z history
• Deadline: T date

In this way, progress is monitored and expectations remain realistic.

6. Change and Additional Work Management

During the project, the client often makes additional requests. The contract should specify how this will be handled:

• When an out-of-scope request comes in, should you accept it in writing?
• Will additional costs be added to the existing budget?
• How many "minor" changes are included in the contract?
• When will I receive payment for the additional work done?

From what I've seen while working with businesses in Alanya, unwritten additional tasks can drag a project down for months. This isn't a master-apprentice relationship; it's a professional business agreement.

7. Liability and Warranty Conditions

What happens if the software is delivered, used, but then a bug is found?

• For how many days will the programmer provide free bug fixes?
• If the software crashes and data is lost, who is responsible?
• If the server goes down, who is responsible (on the hosting side)?
• What is the warranty period? (usually 3-6 months)
• Who is responsible if the customer uploads incorrect data to the software?

Unlimited responsibility ruins a software developer. However, being completely irresponsible also creates distrust in the customer. A reasonable balance must be struck. In our article on hosting control, I explained how these kinds of technical responsibilities can be divided.

8. Privacy and Data Security

If the project involves sensitive client data (client list, pricing, trade secrets), there must be a clause regarding its confidentiality.

• The software developer will not use the customer's data for any other purpose.
• Once the project is complete, the client's data will be deleted from the developer's system.
• The developer will not publish without obtaining a screenshot or sample from the client.
• Compliance with the KVKK (Personal Data Protection Law) or similar legislation will be ensured.

9. Server, Domain and Infrastructure Owner

Where the software will be installed is very important. Will the server be under the control of the client or the developer?

• Who owns the server and who has access to it?
• Whose name is the domain registered under?
• Who provides SSL certificates (secure connection)?
• Who pays for the server costs?
• Who is responsible for backups and backup procedures?

A system running on the developer's server and controlled by the developer does not give the client freedom of action. This should be avoided in the long run. A client-controlled infrastructure is the healthiest option.

10. Communication and Management Process

When decisions are made quickly on a project, the software developer works efficiently. Otherwise, the project is delayed. The following points should be clearly stated in the contract:

• How many meetings will be held per week?
• Who makes the decisions and within how many days is the information provided?
• How many runs are required for a design review?
• Who is the project manager, and do I contact the software developer directly?

This ensures a smooth, predictable, and fast workflow between the parties.

11. Termination and Withdrawal Conditions

Sometimes, it might be necessary to abandon a project midway. What happens in that case?

• How much does a software developer get paid if they terminate the project?
• If the client terminates the project, will they still have to pay for the work already done?
• To whom does the partially completed code and database belong?
• Is information being transferred?

This substance is a preservative, and hopefully it will never be used, but it is essential.

12. Applicable Law and Dispute Resolution

One last, but important point: What happens if a dispute arises?

• Which country's/region's law applies?
• Should reconciliation/mediation be attempted first?
• Or should we go straight to court?
• What will be kept as evidence? (emails, project report, written instructions)

This point is particularly vital when working with international clients (from Germany, the Netherlands, Russia).

Conclusion: Written contracts protect everyone.

A software contract doesn't just protect the client or the developer; it protects both. Thanks to a clear, understandable, and detailed contract:

• The customer knows exactly what they will get for their money.
• A software developer knows what they need to do and their limitations.
• Both sides feel they have been treated fairly.
• When a dispute arises, there is a quick way to resolve it.

For agencies, restaurants, hotels, real estate agents, and e-commerce businesses operating in Alanya, Antalya, and the Mediterranean region, signing a clear contract is just as important as choosing a reliable and professional software partner. Time is wasted on email correspondence. A simple yet clear contract gives everyone their time back.

At Alanya IT Services, we always begin our projects with a written contract. This approach ensures peace of mind for both parties. Before starting a new software project, we recommend checking that all 12 of these points are included in the contract. You can browse our projects and see how we work on our Instagram page .
