There is a minimum ad budget below which paying someone to manage your advertising is arithmetically a bad idea. It is not a sales tactic — it falls out of how the platforms work.
Two separate reasons for a floor
The fee takes too large a share. If management costs a significant fraction of what you spend on media, most of your money is buying oversight rather than customers. The management would have to be extraordinary to beat simply spending that money on ads.
The account cannot learn. This is the bigger one and it is not about fees at all. Automated bidding needs a steady flow of conversions before it stabilises. Below that threshold an account sits permanently in exploration, paying higher costs than it would settle at, producing results too noisy to read.
No agency can optimise its way out of insufficient conversion volume. The learning phase calculator shows where your budget sits against that threshold at your cost per conversion.
An agency on a small account is not a cheap version of an agency on a large one. It is a person being paid to watch something that cannot improve yet.
Where the minimum ad budget actually sits
It depends almost entirely on your cost per conversion, not on a universal number. A business converting at a low cost per lead reaches useful volume on a modest budget. One paying a high cost per acquisition in a competitive category needs several times that for the same learning.
Our own floor comes from that arithmetic rather than from a round number, and we say it on the first call rather than after a proposal. Below that we will tell you what to fix instead.
What to do until you get there
- Run it yourself, badly, on one channel. Genuinely. You will learn what a click costs in your category and what your page converts at, which is information no agency can give you without spending your money anyway.
- Fix the page first. Conversion rate improvements compound with every rupee you later spend. They are also free.
- Fix follow-up. Speed to lead moves results more than most account work.
- Pick one channel. Splitting a small budget across Google and Meta guarantees neither works. Here is how to choose.
- Pay for an audit or a few hours of advice rather than a retainer. You get the thinking without the ongoing fee.
What to be suspicious of
An agency that takes a small account without mentioning any of this. They are either planning to spend very little time on it, or they have not done the arithmetic. Both are bad for you — and the second is worse, because it means the same lack of rigour will apply to your campaigns.
And if you are close
If you are near the threshold and growing, starting slightly early can make sense, provided you both acknowledge that the first two months are setup rather than performance. What does not work is starting far below it and hoping.
The same arithmetic decides whether a trial can produce a readable result — structuring a ninety-day pilot starts with the budget floor. On the fee side, what management actually costs sets out what the number should reflect.
If you want to know honestly where you stand, send us the account — the audit is free and the answer is sometimes "wait six months".
Questions people ask
Why is there a minimum ad budget at all?
Two reasons stack. The platforms need a volume of conversions before bidding stabilises, and below that the account cannot learn. Separately, a management fee that is a large fraction of the media spend means most of your money is buying attention rather than customers.
What should I do if I am below the minimum?
Run it yourself on one channel, with one offer, in one market, and put the money that would have been a fee into media instead. Fix the conversion rate on the landing page while you are there — it raises what every future rupee buys.
Does the floor change by industry?
Yes, because it is really a floor on conversions rather than on rupees. A business with a low conversion rate or expensive clicks needs more budget to reach the same number of conversions, so its floor is higher.
Should I trust an agency with no minimum?
Be careful. An agency with no floor has either not thought about whether you will succeed, or is pricing for volume rather than outcomes. The floor is a sign someone has done the arithmetic.
