ChatGPT Ads Agency vs In-House vs Done-for-You: Which Fits You?
Three ways to run ChatGPT ads, compared honestly on cost, time, control and risk, plus a simple framework for choosing the right one for your brand.
Once you decide to try ChatGPT ads, the next question is who will actually run them. You have three realistic options: do it yourself (or with your team) in OpenAI's Ads Manager, hire an agency, or use a done-for-you service built for the channel.
Each option trades money for time and control in a different way. None is right for everyone. This guide compares them on the things that matter, with rough cost math, and ends with a simple way to decide.
What running ChatGPT ads actually involves
Before comparing options, it helps to list the work. Whoever runs your campaigns needs to:
- Research the questions buyers ask and the messages that sell in your niche.
- Write chat card creative: headline (3–50 characters), body (about 100 characters), image and landing link.
- Write context hints that describe the right buyer situations.
- Check every ad against OpenAI's ad policies, which prohibit unverifiable claims, fake urgency, guaranteed outcomes and implying the ad knows the user's conversation.
- Set up the account, pixel and Conversions API.
- Choose bids (CPC, CPM or oCPC) and budgets.
- Monitor results, test new messages, and refresh creative.
- Report on what is working and decide what to change.
Some of these are one-time tasks. Most are ongoing. The question is who does them, and how well.
Option 1: in-house (DIY in Ads Manager)
You or a team member run campaigns directly in OpenAI's self-serve Ads Manager, which opened to US advertisers on May 5, 2026.
Costs. The tool itself is free. You pay only ad spend, billed by OpenAI, plus the time of whoever runs it. If a marketer spends six hours a week on ChatGPT ads at a loaded cost of $50 an hour, that is about $1,300 a month in labor.
Strengths.
- Full control over every setting and every word.
- No management fees on top of spend.
- Learning stays inside your company.
- Fastest reaction time if the person is dedicated.
Weaknesses.
- Steep learning curve on a new channel with limited benchmarks.
- Creative and policy work takes longer than people expect.
- Easy to deprioritize when other channels need attention.
- Results depend heavily on one person's skill and time.
Best for: brands with an experienced performance marketer who has capacity, or teams that want to own the channel long-term. Our page on DIY in ChatGPT Ads Manager vs SecondWin goes deeper.
Option 2: an agency
A paid media agency adds ChatGPT ads to its services, or a specialist agency focuses on AI channels.
Costs. Agencies typically charge a monthly retainer, often in the $2,000–10,000+ range, and/or a percentage of ad spend, sometimes with setup fees. Pricing varies widely, so ask for specifics.
Strengths.
- Human strategists who can handle complex accounts and multiple channels.
- Can coordinate ChatGPT ads with your Meta, Google and other campaigns.
- Custom reporting and regular calls.
- Useful if you want one partner across everything.
Weaknesses.
- Expensive relative to typical ChatGPT ads test budgets. A $3,000 retainer on $3,000 of monthly spend doubles your cost per acquisition.
- ChatGPT ads are new, so few agencies have deep experience yet.
- Quality depends on who is assigned to your account.
- Longer contracts are common.
Best for: larger brands spending heavily across several channels who want one accountable partner. See what to ask before hiring a ChatGPT ads agency and our ChatGPT ads agency comparison.
Option 3: done-for-you service
A productized service focused on ChatGPT ads that handles research, creative, policy checks, launch and management for a flat fee. SecondWin is one example.
Costs. Flat monthly fees with published pricing, typically lower than agency retainers. Ad spend is paid separately to OpenAI.
Strengths.
- Specialized in one channel, with a repeatable process.
- Predictable cost that does not rise with spend.
- Little time required from your team.
- Usually runs in your own ad account, so you keep the data.
Weaknesses.
- Less custom strategy than a full agency.
- Focused on one channel; it will not manage your other ads.
- Less hands-on control than doing it yourself.
- Fit depends on whether your business matches what the service is built for.
Best for: consumer brands that want to test or run ChatGPT ads properly without hiring or paying agency retainers.
Side-by-side comparison
| Factor | In-house | Agency | Done-for-you |
|---|---|---|---|
| Monthly fee | $0 (labor cost instead) | Often $2k–10k+ and/or % of spend | Flat, published |
| Your time per week | 4–10 hours | 1–2 hours | Under 1 hour |
| Control | Full | Shared | Lower |
| Channel expertise | Depends on your team | Varies by agency | Specialized |
| Multi-channel coordination | Yours to manage | Often included | No |
| Account ownership | Yours | Varies; ask | Usually yours |
| Speed to launch | Depends on learning curve | Weeks (onboarding) | Days |
The cost math at three spend levels
Here is a rough comparison of total monthly cost (fees or labor plus ad spend), using hypothetical figures: in-house labor at $1,300 a month, an agency at $3,000 a month or 15% of spend (whichever is higher), and a done-for-you plan at $299 a month.
| Monthly ad spend | In-house total | Agency total | Done-for-you total |
|---|---|---|---|
| $1,500 | $2,800 | $4,500 | $1,799 |
| $4,500 | $5,800 | $7,500 | $4,799 |
| $15,000 | $16,300 | $18,000 | $15,299 |
At $15,000 of spend, 15% would be $2,250, so the $3,000 minimum still applies. At lower spend levels, fees and labor make up a large share of total cost, which matters because ChatGPT ads tests often start small. Your actual numbers will differ, so plug in your own labor rate and quotes. The CAC calculator helps show how each option changes your cost per customer.
Questions to decide
Work through these in order:
- Do you have someone with paid media experience and five-plus free hours a week? If yes, in-house is viable and cheapest.
- Do you need one partner across many channels? If yes, an agency fits better.
- Is your monthly ChatGPT ad spend under about $10,000? If yes, agency retainers will be a large share of cost.
- Do you want specialized ChatGPT ads execution without hiring? Done-for-you fits.
- Do you sell B2B to teams? Reconsider the channel itself, since those buyers mostly use ad-free paid plans.
Many brands combine approaches over time: start done-for-you to learn what works quickly, then bring it in-house once spend and knowledge grow, or keep a service running while the team focuses elsewhere.
Red flags with any option
- They want to own your ad account. Ad spend, data and history should stay in your OpenAI ad account.
- They promise specific results. Nobody can guarantee ROAS on a channel this new.
- They copy competitor ads. Copying copy, images or brand assets is risky and against policy.
- No policy process. Ask how they check claims before launch.
- No clear reporting. You should see spend, CTR, CPC, conversions and what changed.

FAQ
How much does a ChatGPT ads agency cost?
Pricing varies widely, but traditional agencies typically charge a monthly retainer, often between $2,000 and $10,000 or more, and/or a percentage of ad spend, sometimes with setup fees. Because ChatGPT ads tests often start at a few thousand dollars a month in spend, retainers can make up a large share of total cost. Always ask for a written breakdown before signing.
Can I run ChatGPT ads myself?
Yes. OpenAI's self-serve Ads Manager opened to US advertisers in May 2026 with no minimum total spend and a minimum of about $25 a day per campaign. You will need to write creative and context hints, check ads against policy, set up tracking, and optimize over time. It is cheapest in fees but requires several hours a week and some paid media experience.
What is a done-for-you ChatGPT ads service?
It is a productized service that handles the full process for a flat fee: research, ad creative, context hints, policy checks, launch and ongoing management. Unlike software you operate yourself, the service does the work. Unlike a traditional agency, it focuses on one channel with a standard process and published pricing. Campaigns usually run in your own ad account.
Should my agency or service own my ChatGPT ad account?
No. Keep the ad account in your name and add partners as users or admins. That way your spend, conversion data and campaign history stay with you if you change providers. OpenAI bills ad spend to the account owner, so you also keep direct visibility into what is being spent and can verify every number in Ads Manager.
