The retainer is the safest way for an agency to earn without working.

AAlmost every agency you talk to will sell you the retainer. Easy to see why. From their side, it is the cleanest financial model in the world. Same sum every month, regardless of whether you had a record month or lost money. Cashflow predictability. Easy to scale as a business. Easy to pitch internally: we have X retainer clients, we have 12-month visibility. That is how an agency thinks for itself, not for you.

For you, the model has one large problem. You pay them the same whether they bring you sales or sit on their hands. Zero hit to their pocket when things go bad. And no benefit when things go well either. They do not make more if you make more. So why would they push hard?

I have spoken with too many founders who paid EUR 2,000 a month and saw roughly one hour of work per week in the account. One hour. Out of 168.

Retainer, dissected on a real case

Fixed monthly sum, usually between EUR 800 and EUR 3,000. Covers a package: campaign management, monthly report, weekly or bi-weekly call. Your cost does not move whether sales double or halve. As long as the money hits the agency account on the agreed date, they are satisfied. You are the one sitting on the sidelines hoping.

For the agency, the retainer works like a gym membership. They get paid whether you show up or not. And their incentive is to get as many subscribers as possible, not to make the current ones reach their goals.

I have seen agencies where one account manager had 35 clients. Thirty-five. If you work 20 days a month, that is less than one day per client. And in that day they need to make the report, answer emails, attend the call. How much time is left for real work on your account? Approximately zero. But the EUR 1,500 retainer lands in their account like clockwork, every single month.

Think of a founder who pays EUR 2,400 retainer per month to a mid-sized agency. You ask to see the conversation. Over the last 8 weeks, the agency messages are: report (PDF), call confirmation, and twice "still analyzing the data". Eight weeks. Two hundred words exchanged. Nearly thirty thousand euros a year for two hundred words a month.

Commission, dissected the same way

A percentage of sales driven by ads. Usually 5 to 10%, depending on margin and budget. Sell EUR 10,000 this month, you pay EUR 500 to EUR 1,000. Sell EUR 50,000 next month, you pay EUR 2,500 to EUR 5,000. Your cost scales with what you earn.

Agency earns only if you earn. Earns more if you earn more. No trust needed. Just math. If they earn when you earn, they have every incentive in the world to make you earn. It is not about who is better or more ethical. It is about who has the financial reason to work for you.

That is why commission is our preferred model. Not out of altruism, but because on commission, if you do not make sales, we do not collect either. It is the healthiest possible pressure, because it forces us to deliver. The model does not fit every business, though, and there we work on a fixed, transparent subscription.

The difference in numbers, concrete scenarios

Put yourself on each row. This is where you can see with the naked eye why the model matters more than the sales pitch:

Look at the first row. At EUR 5,000 monthly sales, the retainer eats 30% of your turnover. The agency makes proportionally more than a full-time employee. And they sold nothing. They sent a PDF. On commission you pay EUR 350. Difference: EUR 1,150 per month. Over a year, that is EUR 13,800 staying with you instead of leaving for the agency.

Now look at the last row. At EUR 50,000 monthly sales, commission is more expensive in absolute euros: EUR 3,500 versus EUR 1,500. But you made ten times more than in the small scenario. You are paying 7% of EUR 50,000, not 30% of EUR 5,000. That is called aligned scaling. You grow, they grow. You shrink, they shrink.

And there is one more thing the table does not show but matters enormously. In the retainer scenario, when your sales drop to EUR 3,000 a month, you still pay EUR 1,500. The retainer is 50% of your turnover. On commission, you pay EUR 210. That difference, in bad months, is the difference between surviving and shutting down.

The moment of truth comes at month three

Picture yourself in an agency with 40 retainer clients, all paying EUR 1,000 to EUR 2,000 a month. Results on your account are mediocre. You have messaged the account manager twice, they promised "the team is on it next week". Next week comes and goes. Nobody puts anything on anything.

Meanwhile, another client on commission brings them EUR 5,000 this month because they scaled together. Who gets the attention? Commission agencies cannot afford to ignore you, because their revenue depends on you. It is not generosity. It is survival.

Retainer agencies can afford to put you off, because the cash shows up anyway. Commission is like the gym only charging you for every calorie you burn. Interests are perfectly aligned. And that alignment is all that matters long-term.

The delay mechanism: why your account does not get attention

The problem with retainer is not that the agency is bad. It is that the model creates wrong incentives. An account manager with 30 retainer clients has 30 guaranteed revenue sources. If you call to complain about performance, they have two options. Either allocate two extra hours and lose time from another client paying the same amount. Or send you an email saying "we are reviewing the situation" and move on to the next one.

Guess which option is chosen 9 out of 10 times. Not because the person is lazy. Because the math tells them your time is worth the same with or without extra effort. The retainer eliminates consequence. And when you eliminate consequence, you eliminate motivation.

On commission, the equation shifts completely. If your account drops 30%, the agency revenue drops 30%. There is no delay email. There is urgency. And from urgency come decisions. An account manager on commission who loses sales on your account loses from their own revenue. That is real pressure. Not contractual. Financial.

There are cases where a retainer does make sense

So you do not think I am just selling a line, here is when retainer actually works better for you:

• Your net margin is under 15% and a 10% commission makes you lose money on every sale. A small retainer, EUR 500 or EUR 800, might be cheaper than commission applied on your volume. At thin margins, the percentage bites harder.
• You sell a product or service with very stable turnover unaffected by ads. Rare case, but it exists. Recurring services with high retention, long-cycle B2B subscriptions.
• You need work that cannot be attributed directly to sales: branding, video production, long-term SEO content, PR. Here retainer is the right model because there is no direct sale to take commission from.

These are exceptions. Not the rule. The rule is: if your sales can be directly attributed to ads, commission beats retainer on every relevant dimension. And that is math, not opinion.

How commission works at High-Up LABS

We take 5 to 10% of revenue generated by ads. Exactly how much depends on margin, volume, complexity. Let us put it in concrete numbers. If your margin is 40% and sales are EUR 50,000, 7% means EUR 3,500 for us. You keep EUR 16,500 profit after ads and after commission. That is real money, in your account, that you count.

If next month sales grow to EUR 80,000, we earn EUR 5,600. You keep EUR 26,400. We both earned more. If sales drop to EUR 30,000, we earn EUR 2,100. You keep EUR 9,900. We both earned less. That is fair. Not fair on paper. Fair in the bank account.

Compare with retainer. At EUR 50,000 sales and EUR 1,500 retainer, you pay EUR 1,500 regardless. The agency earns EUR 1,500 regardless. If you drop to EUR 30,000, you still pay EUR 1,500. If you grow to EUR 80,000, you still pay EUR 1,500. The agency does not earn more if you perform. So, honestly, why would they bother making you perform?

This calculation settles any conversation

When you sit down with an agency, you do not need speeches. You need a pen and a calculator. Here is what you do:

1. 01Take your average monthly sales over the last 6 months. Or your estimate if you are starting.
2. 02Divide the proposed retainer by that average. If you land on 15% or more, that is a warning sign. At 20%, the model does not justify itself, because a quarter of what you sell goes to the agency before it reaches you.
3. 03Ask for the equivalent commission offer. If the agency refuses to even discuss the model, you have your answer. The refusal is the information. An agency that knows it delivers accepts commission because it knows it will earn more from it long-term.
4. 04If they accept commission but quote an absurd rate (15% or above), negotiate to 5 to 10%. That zone is the market standard when margin allows.

And one more thing. If the agency accepts commission at 7% but requires a minimum ad budget of EUR 2,000 per month, that is reasonable. It is not a trap. It is a filter. It means they want to work on accounts with enough volume for the work to pay off. A 7% commission on EUR 500 in sales does not cover even the minimum effort. A serious commission agency does not take any client. It picks clients with real potential.

When commission is the obvious answer

For most businesses selling online, commission beats retainer on every relevant dimension. If you tick the points below, you should accept paying only for results:

• Your net margin is over 20%. You can afford to give up 5 to 10% on the sale and still have healthy profit left.
• Your ad budget is over EUR 2,000 a month or sales over EUR 5,000 a month. The current volume is enough to justify agency work.
• You want a partner growing with you, not a vendor ticking off a monthly report.
• You are willing to pay more in good months, knowing in slow months you pay less. Fair both ways.

If you tick all four, you need no further argument. The commission model is the right frame. The retainer, in your context, is a cost with no connection to performance. It is a subscription to a magazine you do not read.

One last thing nobody tells you

Large agencies in Romania do not work on commission for the same reason you do not change your business model when it is working: they already have predictable cashflow. They have 40, 60, 100 retainer clients. They have salaries to pay, offices to rent, events to sponsor. Commission introduces variability. And variability is the enemy of large structures with large fixed costs.

But small, agile agencies that know what they are doing work on commission for a simple reason. They know if they deliver, they earn more than on retainer. And they know if they do not deliver, they lose. That is the position you want as a founder: working with someone who loses when you lose and wins when you win.

It is not about trust. It is about alignment. Trust breaks at month 3 when the report looks beautiful and the account looks empty. Financial alignment never breaks because it is built on math, not promises.

Bottom line

• Retainer shifts risk onto you. Agency gets paid regardless. You are left with the result, good or bad.
• Commission shares risk. Agency earns only if you earn. If you do not earn, they lose too. That is alignment.
• For e-commerce and services with trackable sales, commission is the right frame. Retainer is the exception, not the rule.
• If an agency refuses commission with vague arguments, the refusal is the information you needed. An agency that knows it delivers has no reason to refuse commission.
• It is not about who is more ethical. It is about who has the financial motivation to work for you. And financial motivation is stronger than any promise.
