Ad spend-linked billing for freelance media buyers

A freelance media buyer managing three or four small clients hits a recurring budgeting problem: their clients' monthly ad spend swings wildly — $500 one month, $3,000 the next — but every management tool they use charges a fixed monthly fee regardless. They're either eating the cost during slow months or passing it along and losing clients over it. One complaint specifically named $159/month as painful 'for a growing company,' and another flagged that the pricing model 'needs to be simplified' with 'easier parameters to integrate with the business.'

The core structural issue here is that these tools are priced for agencies with predictable retainers and steady client rosters. A freelancer's economics don't work that way — their income is variable, their client base turns over, and they often manage accounts at wildly different spend levels simultaneously. The incumbents have no incentive to fix this because agencies (their primary buyers) prefer predictable costs and pay without complaint.

What's missing is a management layer where the monthly cost scales directly with the total ad spend under management — so a freelancer paying nothing when clients pause campaigns and paying proportionally when spend ramps up. That's how performance-based client relationships already work; the billing infrastructure should match. Without it, freelancers either absorb fixed fees as a business loss during slow periods, manually re-activate and cancel subscriptions (which is its own headache), or avoid using management tools altogether and do everything in native dashboards — which costs them hours per week and limits how many clients they can take on.

What to build

Build a multi-channel ad management tool for freelancers that charges a percentage of total managed ad spend per month (e.g., 1–2%), with a monthly floor low enough to cover infrastructure costs, automatically adjusting the bill based on actual spend pulled from connected ad accounts.

Where to start

Target freelancers who already use Slack communities and forums like r/PPC or the Freelance Media Buyers Facebook group — they're vocal about pricing frustrations, reachable at near-zero CAC, and will tell you exactly what spend percentage feels fair before you have to guess.

The hard part

Spend-percentage billing is simple to explain but hard to collect cleanly — ad spend numbers from connected platforms can lag, be revised, or include credits and refunds, which means you need reliable reconciliation logic before you can invoice accurately without disputes.

How it makes money

Percentage of total managed ad spend per month (1–2%), with a minimum monthly floor of ~$15 to cover fixed costs; optional add-ons like client-facing reporting or white-label invoicing charged as flat monthly upgrades.
