I've heard this story more than forty times now. Romanian founder, decent revenue, signs with an agency because a friend at another business „is happy with them". Three months later he calls scared because reports look great and his bank account doesn't. Someone paid €10,000. Sometimes €20,000. Once €47,000. I was usually the second or third person on his list of people who might fix it.
Here's the thing. All these stories start the same way. The signs were there from the first email. They were on the agency site. They were in the contract. Nobody knew what to look for.
So I wrote them all down. If the offer you've got on the table ticks three or more of these, close the laptop and walk. You lose nothing except the time of a follow-up email.
1. They tell you upfront „we don't guarantee results"
The line itself is standard. Any serious lawyer puts it in the contract, because nobody can promise numbers in a field with this many variables. That's not the issue. The issue is when they throw it at you verbally, on the first call, as a preventive excuse. Means they've learned to cover themselves before they deliver. If they believed they could deliver, they'd talk about how they take partial responsibility. About KPIs. About clauses that cost them if they miss. Not about disclaimers.
2. „First month free", on a 12-month contract
Oldest trick in the book. First month free, you relax. You sign the other 11. Month 2 nothing happens but you tell yourself they just started. Month 3, „let me give them another chance, I already paid". Month 4 your head's already on another project and you're paying on auto-pilot. Month 7 you look at the bank statement and you've handed over €14,000 for weekly PDFs.
An agency that knows it delivers doesn't need to lock you in for 12 months. If it works, you stay on your own. If it doesn't, you should be able to leave on 30 days.
3. 15% on top of ad budget, as „management fee"
This model makes the math ugly in real time. On €10,000 ad budget, you pay €1,500 extra just for someone to watch the account. If they optimize badly, you lose twice. Once on ads that burn. Second on the fee that shows up regardless. And worst, the agency is incentivized to push your budget up, not performance, because 15% of €20,000 is twice 15% of €10,000.
4. They won't give you admin access
Meta account, Google account, pixel, audiences. All under their name. You get screenshots. In some cases the business manager itself is registered under their company, not yours. When you want to leave, you discover you're leaving empty-handed. Zero history. Zero custom audiences. Pixel from scratch. The next agency starts from zero and has to re-learn everything, meaning another 3 months lost.
5. They sell you metrics nobody else uses
„Efficient ROI." „Influencer amplification." „Calibrated reach." „Qualitative engagement." If you've never seen them in Meta Ads Manager or GA4, it's because they don't exist there. They're invented to feel like performance. Real metrics have names like CPM, CPC, CTR, CPA, ROAS, POAS, AOV. If your monthly reports are full of terms no specialist recognises, someone's hiding behind vocabulary.
6. Month four, still „optimizing"
Optimization has a clear cycle. Month 1, setup. Months 2 and 3, testing creatives, audiences, landings, products. Month 4, you start scaling what works. If at month 4 you're still being explained „the ecosystem" and „the algorithm maturing", the foundation is rotten. It's not a time issue. It's a decisions-not-made issue.
7. Reports are about impressions, not sales
You get a pretty PDF with graphs. „1.2 million impressions. 45 thousand clicks. Above-average CTR." Impressive if you're on LinkedIn impressing other marketers. If you're a founder and your product costs 300 lei, only one question matters: how many sold. If that question isn't on page one, page one is decor.
8. On the first call they don't ask about margin, LTV, CAC
A serious sales call starts with 30 minutes of the agency nose-deep in your business. What you sell, to whom, what's the net margin after all costs, what a purchase costs you now, what a customer is worth over their lifetime, what tracking you have set up. If the whole conversation is „what's your budget and when can we launch", they won't optimize for you. They'll put you through the pipeline as a number in Q2.
9. 30 logos on the site, zero case studies with numbers
The agency homepage looks like a Champions League banner. Nike, Coca-Cola, IKEA, BMW. You ask for a concrete case study with numbers. You get „under NDA" or „I'll send the general deck". NDAs are real, fine. But an agency that's worked with 30 brands should have at least two public case studies with numbers, even anonymized. If all they can show you is a logo, the collaboration was probably a one-month project four years ago, with nothing worth writing up.
10. The first email reads exactly like ChatGPT
„We have carefully studied your business and identified significant growth potential." Then your name inserted badly in two spots. Zero specific detail about what you sell, for how long, to whom. If the agency didn't invest 30 minutes looking at your site before writing the proposal, they won't invest 30 minutes after you sign. The same energy will go into your campaigns.
11. They promise magic numbers, without seeing your account
„We'll grow your sales by 400% in 90 days." „ROAS 10x guaranteed." „We have a proprietary formula." Nobody can pull those numbers out of their mouth without having seen at least a screenshot from your Shopify. Real marketing is incremental. A 30 to 80% growth in 6 months is a good result. A 400% jump in 3 months happens in two cases. Either you were at zero and anything is growth. Or it's a lie.
How an agency that actually wants to work with you behaves
- Asks for read-only access to your accounts before any offer and runs an audit.
- Talks about POAS, not just ROAS, because they know one is decorative without the other.
- Leaves you in full control of your accounts, you admin, them access.
- Promises process and transparency, not numbers they have no way of knowing.
- Contract exits in 30 or 60 days, no hidden break fee.
- When something's not working, they tell you that week, not at the monthly report.
