The line that stops Ray is on the second page of the proposal: "Management fee: a percentage of ad spend." He has read it more than once since Tuesday. His plumbing company is doing fine on referrals, but the phone has gone quiet on a few slow days, and an agency rep has offered to run his Google ads. The proposal is clear about the fee and the start date. It doesn't say whose name the ad account will be under, what the fee includes, or what Ray would walk away with if he cancelled. The rep would like an answer by Friday.
Ray's situation is the general case for anyone searching for plumbing PPC services. You are rarely choosing between running ads and not running them. You are reading a document written by the seller and trying to work out what each line means for you. This page goes through that document the way a careful buyer would, so you can decide whether to sign, negotiate, or run the ads yourself.
Split the proposal into what you are actually buying
| Line in the proposal | What it should mean | What to ask |
|---|---|---|
| Account setup | Building campaigns, choosing keywords, writing ads, connecting call and form tracking | Is this a one-time charge, and do I keep everything it produces? |
| Management fee | Ongoing changes: search terms trimmed, bids adjusted, ads tested | What specific tasks happen each month, and who does them? |
| Ad spend | Money paid to Google for clicks, separate from the agency's fee | Is it billed to my card or through the agency? |
| Reporting | A regular summary of what the ads produced | Can I see a sample report before I sign? |
Who holds the keys when the contract ends
Ownership is the line most proposals skip, and it matters most if things go badly. The safest arrangement is a Google Ads account created under your business, with your payment method on file and the agency added as a manager. You can then remove them at any time and keep the history: search terms, ad copy, conversion settings. If the agency runs everything inside its own account, you may leave with nothing except the memory of what you paid. Ask for the ownership arrangement in writing, including who owns the call tracking numbers and the tracking setup.
Small numbers, held loosely
It helps to know how thin the search behind this topic is. Combined, the plumbing ppc services cluster draws about 90 searches a month across just 2 distinct queries. Even the single phrase swung from 210 a month in September 2025 to 10 in February 2026. Read that as a niche question that only a few owners ask, and not as a trend to plan around. The cost side is more concrete: the highest top-of-page bid advertisers pay is $43.96. That is a ceiling, not what you should expect for every click, but it shows that clicks in this trade can be expensive. When each click can cost that much, a management fee calculated on spend and a careless setup can both hurt.
How the fee structure shapes behavior
A percentage of spend pays the manager more when you spend more, so make sure someone is looking out for your budget. A flat fee is easier to predict, but it can reward doing the minimum. Per-lead pricing sounds fair until you ask how a lead is defined and who verifies it. None of these is wrong. Each one pushes the person managing your account in a particular direction, so pick the one whose incentive you can live with. Our guide to PPC management pricing goes deeper on the structures.
Doing it yourself is a legitimate answer
If you have the time to check the account weekly and are comfortable with a dashboard, running a small campaign yourself is reasonable, especially at a modest budget. Help is worth considering when the account is large enough that a few wasted clicks add up, when you don't trust your tracking, or when nobody in the company has the hours. A good middle path is a one-time review of your setup, with you continuing to run the ads. It costs less than ongoing management and you keep the account either way.
What to do before Friday
Ask for the sample report, the ownership answer in writing, and a plain description of what the monthly fee covers. Compare those against the table above. If the answers are clear, you have a vendor worth a short first contract. If they are vague, you have learned that cheaply. Either way, you no longer have to decide by the rep's deadline, only by yours.
