Ecommerce PPC Agency Pricing and Management Fees

Short answer: an ecommerce PPC agency charges either a flat monthly retainer, commonly $1,500 to $5,000 for a store running Google Shopping and Performance Max, or a percentage of ad spend, usually 10 to 20 percent with a minimum fee. Some add a one-time setup fee of $500 to $2,000. Ad spend is always on top. Of the Shopify-focused agencies we checked, one prints a starting price on its own site: $5,000 a month, month to month.

Fee figures come from pages agencies publish about their own pricing or the market: Kobe Digital’s ecommerce PPC pricing guide, Top Growth Marketing’s Shopify agency list, Taylor Sicard’s Google Shopping cost breakdown, and New Media’s 2026 PPC management cost article (all read October 14, 2026). Every source sells the service it prices, so read the numbers as asking prices. No neutral body audits agency fees, and most agencies still quote after a call.

Ecommerce PPC agency pricing at a glance

Ecommerce agencies sell the same work, Shopping feeds, Performance Max, search and remarketing, under four price tags. Here they are with the source for each figure.

The ranges overlap because they describe different stores. A $5,000 a month Shopping account and a $150,000 a month account across Google, Meta and Amazon both get called "ecommerce PPC", and the agencies price them very differently.

What the fee costs at four spend levels

The model matters more than the headline rate, because the same agency can be cheap at one budget and expensive at another. This table applies the published ranges to four monthly budgets. The percentage column assumes 15 percent with a $1,500 minimum; the retainer column uses the $5,000 starting price from the one agency that prints it.

Two things jump out. Under about $5,000 a month, the minimum fee makes any agency expensive, which is why Taylor Sicard puts the practical floor there: a $1,500 minimum on $3,000 of spend is a 50 percent rate. And above roughly $30,000, a flat retainer becomes the cheaper model, which is why larger stores push percentage agencies to cap the fee or step the rate down.

How the fee changes your break-even ROAS

The fee is easiest to judge in the number your store already lives by. Break-even ROAS is 1 divided by your gross margin: a product line with a 40 percent margin breaks even at a ROAS of 2.5, meaning $2.50 in revenue for every $1 of ad spend. A management fee is a cost of that same revenue, so it raises the bar.

• At 15 percent of spend, every $1 of ads really costs $1.15, so break-even moves from 2.5 to 2.88.
• At a $1,500 minimum on $5,000 of spend, every $1 costs $1.30, and break-even moves to 3.25.
• At a $5,000 retainer on $15,000 of spend, every $1 costs $1.33, and break-even moves to 3.33.

That calculation is only as good as the margin you put into it, and plenty of stores work from a guess. If yours does, turn the bookkeeping export into a proper profit and loss statement before the agency call, so the margin you quote is the one your books show after shipping, payment fees and returns.

How much should a small ecommerce store pay for PPC management?

A store spending under about $5,000 a month on ads should usually pay well under $1,500 a month for management, which in practice means a freelancer on a small flat fee, a part-time in-house owner of the account, or running Shopping and Performance Max yourself with good tools. Agencies with a $1,500 minimum turn that budget into a 30 percent or higher fee before any results.

Between about $5,000 and $30,000 a month, a specialist ecommerce agency on a percentage or modest flat fee is usually the efficient choice, because feed work and campaign structure are where the gains are and a generalist will miss them. Above that, compare a capped agency fee with the cost of a hire; our Shopify CRO agency vs in-house breakdown runs the same decision for the conversion side of the store.

What ecommerce PPC management should include

Ask for the scope in writing. For a store selling through Google, a fair monthly fee normally covers:

• Merchant Center health and product feed work: titles, attributes, disapprovals and custom labels by margin or best sellers.
• Shopping and Performance Max campaign structure, with brand and non-brand separated so branded sales do not flatter the results.
• Search campaigns, negative keywords and search term review.
• Conversion tracking checks, so the purchase value Google optimizes on matches the order value in your store.
• A monthly report on revenue, ROAS and new customer share, not only clicks and impressions.

What it usually does not include is the page the click lands on. Product page and checkout changes are the store’s job, or a separate project. That gap is where most of the fee gets wasted.

Why the product page decides whether the agency fee pays

An agency works on the cost of a click. The page works on what the click turns into, and the second number moves revenue at least as much as the first. A worked example with round numbers: $15,000 a month at a $1 average cost per click buys 15,000 visits. At a 2 percent conversion rate and an $80 average order, that is 300 orders and $24,000 in revenue, a ROAS of 1.6. Lift the conversion rate to 2.4 percent and the same spend makes 360 orders and $28,800, a ROAS of 1.92, without the agency touching a bid.

So before you sign, check the pages the ads will land on. The usual leaks on ecommerce pages are a shipping cost that appears only at checkout, a buy button below the first screen on a phone, an account wall before payment, and pages weighed down by app scripts. Converto audits a product, category or landing page from a pasted URL and ranks those findings with the measurement behind each one, from $29 a month billed yearly. The checks are explained for product pages on ecommerce product page optimization, for the checkout on checkout page optimization, and by platform on BigCommerce conversion rate optimization and WooCommerce conversion rate optimization.

Questions to ask an ecommerce PPC agency before signing

• What exactly does the fee cover at my spend level, and what happens to the fee when I raise the budget?
• Is there a minimum term, and what is the notice period?
• Is feed management included, and who fixes Merchant Center disapprovals?
• Will brand and non-brand results be reported separately?
• Who owns the Google Ads and Merchant Center accounts if we part ways? The answer should be you.
• Do you change landing pages, or only recommend changes, and is that billed extra?

Is an ecommerce PPC agency worth it?

An ecommerce PPC agency is worth it when the fee is a small share of spend, roughly 15 percent or less, when it brings feed and Performance Max skill you do not have in house, and when your product pages already convert well enough that cheaper clicks turn into orders. It is rarely worth it below about $5,000 a month in spend, or while the pages the ads land on still leak, because then you are paying a specialist to send more visitors to a page that loses them.
