The two fee models, compared in plain numbers.
A fixed fee, regardless of spend. Predictable, easy to budget, and your fee doesn't climb just because you scale your ad budget. The provider earns the same whether you spend $5K or $50K, so the incentive is to keep you happy and efficient. This is what SolerAds uses.
Usually 10-20% of what you spend. Cheap at low budgets, but it rises automatically as you scale, even if efficiency drops. The hidden flaw: the provider earns more as your spend grows, whatever the results. If you use this model, demand a cap.
There's a spend level where flat fee becomes the cheaper option. Roughly:
If you spend a few thousand a month, 15% of spend can undercut a flat retainer. Percentage may win, short term.
Once you're spending real money, 15% of a large budget dwarfs a flat fee, and you're paying more every month you grow. Flat wins, and keeps winning.
The deeper point: a flat fee aligns your provider with efficiency; a percentage fee aligns them with volume. Decide which behavior you want to pay for.
