Use an agency when you need a full ads function this month and your budget does not yet justify four salaries. Build an in-house team when ad spend is steady, your product needs deep knowledge, and you want speed and control. Many brands run both: a small in-house lead plus an agency or freelancers for the heavy lifting.

## Side by side

| | Agency | In-house team |
|---|---|---|
| Time to start | Weeks | Months (hiring and training) |
| Cost shape | One monthly fee, easy to stop | Salaries, tools and hiring cost |
| Product knowledge | Builds slowly, resets if staff change | Deep and stays with you |
| Skill range | Wide, shared across clients | You hire each skill |
| Speed on a daily call | Slower, via account manager | Fast, same room |
| Fresh ideas | Seen across many brands | Risk of seeing only your own |
| Who owns the learning | Partly the agency | You |

## A worked example

Say a brand spends INR 8 lakh a month on ads. These numbers are made up, so use your own.

**Agency:** INR 1,60,000 a month for media buying, creative direction and reports.

**In-house team of three:**

| Role | Monthly cost to company |
|---|---|
| Performance marketer | INR 70,000 |
| Creative strategist | INR 90,000 |
| Video editor | INR 45,000 |
| Tools and software | INR 30,000 |
| **Total** | **INR 2,35,000** |

The in-house team costs INR 75,000 more each month. It also needs two to three months to hire, and it takes a few weeks to learn the product. After that, it ships new ads in days, and the knowledge stays with you.

A sensible rule: if the extra INR 75,000 buys you a faster test cycle and your spend keeps growing, move in-house. If your spend swings from month to month, keep the agency.

## How to decide

1. **Is your spend steady?** Steady spend supports salaries. Uneven spend favours a fee you can stop.
2. **How fast must you test?** If you need new creative every week, in-house wins.
3. **Do you have someone who can lead?** A team without a strong lead drifts. An agency can stand in until you find one.
4. **How big is your product knowledge gap?** A technical product needs people who learn it deeply.

## The hybrid that often works

Keep one in-house owner for strategy and results. Use an agency or freelancers for media buying and production. The owner reads the numbers, such as [CAC](/glossary/cac), and sets the plan. Ask for the same [weekly report](/templates/weekly-ad-report-template) from everyone so you can compare. The [creative strategist](/glossary/creative-strategist) role is often the first in-house hire worth making.

For smaller budgets, see [agency vs freelancer](/compare/agency-vs-freelancer-for-ads). If you want help picking a model, [Marxx for brands](/for/brands) has a creative strategist and agency service for teams that want a hybrid. We make Marxx, so weigh that.

## FAQ

### When should I bring ads in-house?

When spend is steady, you test new creative every week and the agency fee is close to what the team would cost. Moving earlier often leaves you with one tired person doing everything.

### Can I switch back to an agency later?

Yes. Keep the ad account in your name and keep your creative files, and a switch in either direction stays simple.
