Working With an Agency on Copywriting: Who Writes What

Many agency projects slow down for the same reason: the words. The designs are ready, the development is waiting, and nobody has written the website copy, campaign headlines or product descriptions. The client thought the agency would write it. The agency assumed the client would supply it. Weeks pass.

Copywriting is one of the most under-planned parts of agency work. Clear decisions about who writes what, and how, make projects faster and the results better.

Decide ownership at the start

Before the project begins, agree on who is responsible for copy. Common arrangements include:

• The agency writes everything, based on interviews and materials you provide
• The client supplies drafts, and the agency edits and polishes them
• A split, where the agency writes marketing copy such as headlines and campaign lines, and the client supplies technical or factual content such as specifications and policies
• The client writes everything, and the agency only places it into designs

Each option affects the price, the timeline and the quality. Make sure the proposal states clearly which one applies. Copywriting is real work, and if the agency writes, it should be in the scope and budget.

What the agency needs from you

Even when the agency writes, you provide the raw material. Good copywriters need:

1. Clear information about your products, services and prices
2. Who your customers are and what they care about
3. Common questions and objections from real customers
4. What makes you different from competitors, in your own words
5. Your tone of voice preferences and brand guidelines
6. Any facts, claims or certifications, with proof
7. Words or phrases you must use or must avoid

A short interview or workshop is often the fastest way to gather this. Many owners explain their business better in conversation than in writing.

Facts are the client's responsibility

Regardless of who writes, you are responsible for checking that every fact is correct. Prices, specifications, opening hours, certifications, legal statements and claims about results all need your approval. An agency writer cannot verify what only you know.

Pay special attention to regulated areas, such as health claims, financial products and halal status. Incorrect claims can create legal and reputational problems.

Key takeaway: The agency can make your words clearer and more persuasive. Only you can make sure they are true.

Languages and localisation

Many Malaysian businesses need copy in English, Bahasa Melayu, Chinese or Tamil. Decide early which languages are needed and who will handle each. Translation and copywriting are different skills. Good bilingual copy often needs to be written or adapted for each language, not translated word for word.

If the agency will handle multiple languages, ask who will write each language and whether a native speaker will review it. Our guide on tone of voice in English and Bahasa Melayu covers how to keep your brand consistent across languages.

Build copy into the timeline

Copy should come before or alongside design, not after. Designers work best with real words, because real headlines and paragraphs affect layout. Placeholder text often hides problems, such as headlines too long for the space or sections with nothing meaningful to say.

Set deadlines for copy drafts, review and approval in the project plan, just like design milestones. If you are supplying copy, be realistic about how long it will take your team alongside daily work.

Reviewing copy effectively

When reviewing copy, read it as a customer would. Does it answer their questions? Is it clear what to do next? Does it sound like your brand? Read it aloud, as awkward sentences become obvious.

Consolidate feedback from your team before sending it to the agency. Conflicting comments from different people slow the process and confuse writers. Be specific: "This paragraph overstates our delivery speed" is more useful than "Not quite right".

After launch

Copy is not finished at launch. Watch how customers respond. If people still ask questions that the website should answer, update the copy. If a headline does not attract clicks, test an alternative. Some agencies offer ongoing content support, while others hand over and step back. Agree on this as part of the project.

FAQ

Is copywriting usually included in a website quote?

Not always. Many quotes assume the client supplies content. Check carefully and ask for copywriting to be priced separately if needed.

Can AI tools write our copy?

They can help with drafts, but copy still needs human review for accuracy, tone and local context. Ask your agency how they use such tools.

How many revision rounds are normal for copy?

Two rounds is common, but it depends on the agreement. Clarify the number in the proposal.

Clear copywriting responsibilities prevent one of the most common project delays. Decide who writes what, provide good material, check every fact and build copy into the timeline, and your project will have words that work as well as the designs.
