Dark navy Lazy Ads hero: sleeping panda between Percent of spend and Flat SaaS tiles. Headline How the bill works. — How the bill works: percent of spend vs flat SaaS.

Some AI ad tools tax spend. Some charge a subscription.

The product demos all look adjacent. The bill does not.

Two honest families: percent of spend vs flat SaaS. This is not a /vs page. Public fee language only. No case studies. No invented ROAS.

If you already have an agent, the fee model is the product. A closed team and a pipe can look the same in a screen recording. They do not look the same on an invoice. What BYOA means for ads is the definition of the pipe. This post is how the bill is built.

Percent of spend is still a pipe. The meter is media.

A spend tax is a bet, not automatically a scam. The vendor is saying their cut should rise when your media rises. That can be a partnership. It can also be a second tax on work you already pay an agent to do.

If you already have Claude, Cursor, or Hermes, you may pay twice: model tokens plus a cut of media. The BYOA definition is the other shape — a flat subscription for the pipe, not a meter on spend.

The numbers below are public fee language. If those vendor pages change, believe their current page over this post.

Two cards defining percent-of-spend fees (Zeely partner path, Synter 3% after first write) versus flat SaaS (Lazy Ads public cards). — Two honest families: percent of spend vs flat SaaS. Public fee language. Not a savings claim.

Zeely: up to 12% is one Meta path, not every user

Zeely is Meta-sided.

The up to 12% figure is the Meta partner-account path — ads run through Zeely's partner setup. If you run on your own Meta account, Zeely does not add that extra fee. Booster can cut the partner-path percentage.

Do not treat 12% as the price of every Zeely user. Do not treat it as a Google number. Zeely is not a nine-network media buyer.

That hedge is the whole point of reading the fee, not the homepage. A partner-account cut and an own-account subscription are different products that share a logo.

Synter: 3% after the first write, on top of the plan

Synter is an ads MCP.

Public pricing is a fixed 3% of managed ad spend after the first successful write, and a subscription: Solo $20/month or Scale $500/month. The 3% is not a substitute for the plan. You pay the plan. Then, after the first successful write, you also pay 3% of managed spend.

Reads are framed as free. Writes are where the 3% starts.

If you wanted a pipe you can point Claude at, that part is real. The meter is still tied to how much you advertise, and it sits on top of $20 or $500, not instead of it. If Synter's page changes, believe their current page over this paragraph.

Madgicx is a subscription. Do not quote it as a spend tax.

Madgicx is a Meta-only subscription. Their academy is explicit they do not manage Google ads. Other networks are reporting.

Do not quote Madgicx as a percent of spend. It is not a nine-network pipe. Put it in the subscription column, then notice the column is still Meta.

A multi-platform AI ad manager has to get the network count right before it gets the fee right. Meta is one network (Facebook + Instagram). Google is a different write path. Reporting is not buying. Google-management invoice angle: Flat fee Google Ads.

Lazy Ads is flat SaaS on every public card

No card takes a cut of spend. The media still goes to the networks.

BYOA: $19/month annual, $24 monthly. 33-tool MCP bridge. No Lazy Ads AI. No percent of spend.
Starter: $79 annual / $99 monthly. Full MCP, 45 tools, Lazy Ads AI.
Growth: $199 / $249. REST API starts here.
Scale: $399 / $499.

Nine networks: Meta (Facebook + Instagram), Google, TikTok, LinkedIn, Reddit, Apple, Bing, ChatGPT, and Snapchat. Free users have zero AI tokens. The free path is onboarding and competitor ad browse.

Compare the cards on pricing. This list is the public math, not a custom quote.

A hypothetical $10,000 Meta month — not a customer story

Table titled Hypothetical arithmetic for $10,000 Meta spend: Zeely partner path $1,200; Zeely own-Meta no extra spend fee; Synter 3% + Solo $20 = $320 or + Scale $500 = $800; Lazy Ads BYOA $19 annual / $24 monthly. — Hypothetical arithmetic on $10,000 Meta spend next month. Not a customer story. Not a savings claim.

These are arithmetic on public fees. They are not a case study, a review, or a ROAS claim. Your month will be whatever your accounts actually spent.

Zeely partner-account path at 12%: $1,200. Zeely on your own Meta account: no extra Zeely spend fee (you still pay their subscription).

Synter: 3% = $300 plus Solo $20 ($320) or Scale $500 ($800).

Lazy Ads BYOA: $19 annual or $24 monthly. The $10,000 still goes to Meta.

The $10,000 is the media. The fee-model question is what sits on top of it. A partner-path cut, a write-triggered 3% plus a plan, or a flat pipe. If the vendor pages move, redo the arithmetic from their current page.

Two other columns, so they do not leak into this one

Playad is a closed AI team. Different column. They hire the agents. You approve output. That is not a percent of spend and it is not BYOA. The definition is in what BYOA means.

Marketer.com is a Shopify box. Different column. Do not read a Shopify-scoped product as a nine-network media buyer.

FAQ

Is a percent of spend automatically a bad deal?

No. A spend tax is a bet, not automatically a scam. It is a bad surprise if you thought you bought a subscription and the invoice tracks media. It is a worse surprise if you already pay for Claude, Cursor, or Hermes and then pay a cut of spend for a pipe.

Does Zeely charge every user 12%?

No. The up to 12% figure is the Meta partner-account path. On your own Meta account, Zeely does not add that extra fee. Booster can cut the partner-path percentage. It is not a Google number, and Zeely is not a nine-network media buyer. If their page changes, believe their page.

Does Synter's 3% replace the monthly plan?

No. Public pricing is 3% of managed ad spend after the first successful write, and Solo $20/month or Scale $500/month. The 3% is not a substitute for the plan. Reads are framed as free. Writes are where the 3% starts.

Does Lazy Ads take a cut of spend?

No. Every public card is flat SaaS. BYOA is $19 annual / $24 monthly for the 33-tool MCP bridge and no Lazy Ads AI. Starter, Growth, and Scale are subscriptions. REST starts at Growth. The $10,000 in the hypothetical still goes to Meta.

What does free include?

Onboarding and competitor ad browse. Free accounts have zero AI tokens. Subscribe on pricing when you want the pipe or Lazy Ads AI.

Read the fee, then pick a door

Five-step checklist for reading an AI ad tool pricing page, including Meta as one network and ignoring ROAS you cannot tie to an account you own. — Five steps: find spend, find free, count networks correctly (Meta = FB+IG), can your agent call a documented MCP URL, ignore ROAS you cannot tie to an account you own.

If the demo could have been anyone's, read the invoice shape. Percent of spend, or flat SaaS. Closed team, Shopify box, or a pipe you point your own agent at.

Start free the honest way: finish onboarding and browse competitor ads. When you want a flat plan, compare them on pricing. If the question was what BYOA means, that post is already written. If the question was nine networks on one dashboard, start with the multi-platform map.
