We charge a flat fee, not a percentage of spend
Percentage pricing pays an agency to spend more of your money. Ours means telling you to cut spend costs us nothing.

Ecommerce PPC Managed Against Profit, Not The Number The Platform Reports
Techzenix runs Google Shopping, Performance Max and paid social for online stores. We are paid a flat fee rather than a percentage of your spend, which means recommending you spend less costs us nothing.

What we do
PPC judged by contribution margin per order.
Techzenix is an ecommerce PPC agency that manages paid advertising for online stores. Ecommerce PPC covers Google Shopping, Performance Max, search, paid social and the product feed work that determines whether any of it performs. As a google shopping agency we manage accounts for direct to consumer brands, multi channel retailers and B2B sellers across the United States, United Kingdom and Europe. PPC for ecommerce is judged here by contribution margin per order, not by the return figure the ad platform reports.
Why it misleads
Why most ecommerce PPC accounts look profitable and aren't.
Four problems account for nearly every account we audit that reports well and earns badly.
Same account, two stories — flip the view.
- Attribution
Platform reported return is double counted
Meta claims a sale. Google claims the same sale. Your email platform claims it too. Add the reported figures and they exceed your actual revenue. A four times return in the platform can be a 1.6 times blended return in reality, which at typical ecommerce margins is a loss on every order. The number to manage against is total revenue divided by total spend across everything.
4.0×reported1.6×reality - Product feed
The product feed is neglected and it decides Shopping performance
Shopping and Performance Max serve from your feed, not from keywords. Disapproved products, thin titles, missing attributes and stale pricing quietly cap performance no matter how the bidding is set. Most accounts we audit have products that have been disapproved for months and nobody noticed.
Feed finereportedProducts downreality - Brand terms
Brand terms inflate the reported result
A large share of many accounts is spend on people searching your own brand name, who were going to arrive anyway. It reports beautifully because those clicks convert, and it hides how the rest of the account is performing. Splitting brand from non brand is usually the first honest number an account produces.

Performance Max is treated as a black box and left alone
It is opaque by design, which is not a reason to leave it unmanaged. Asset group structure, product segmentation, audience signals and exclusions all still matter. Accounts that switch it on and walk away tend to spend a rising share of budget on their own brand.

What we manage
It all starts with measurement.
Our ecommerce PPC services and ecommerce PPC management work start with measurement, because managing to the wrong number is worse than not managing at all.
Module 1 / 7
Measurement setup
Blended return and contribution margin reporting built first, with conversion tracking verified and brand split out.
Who we work with
Who we work with.
Direct to consumer brands
Shopping and paid social carry most of the volume. First order profitability and repeat rate decide whether scaling is viable.
In practice
What this looks like in practice.
A direct to consumer home goods brand, Shopify Plus.
Their previous agency reported a 4.1 times blended return and revenue was growing, yet cash was tightening every quarter. Platform reported conversions exceeded actual orders by 38 percent. Nine hundred products were disapproved in Merchant Center. Brand search accounted for 31 percent of spend and was reported alongside everything else.
Techzenix rebuilt reporting around contribution margin, cleared the feed disapprovals, split brand from non brand, and restructured Performance Max by product margin rather than by category.
The trade that matters
Platform reported return 4.1× → 3.2×Contribution margin per order $11.4 → $18.3
- Monthly ad spend$142,000→$0
- Platform reported return4.1 times→0.0 times
- Contribution margin per order$11.40→$0.0
- Disapproved products900→0
- Brand share of spend31 percent→0 percent
The reported return figure got worse and the business became significantly more profitable. That trade is the entire point, and an agency paid a percentage of spend will not propose it.
How we work
Four stages, and the feed fixed before the bids.
- 01
Review
We audit your account, your Merchant Center feed and your actual blended return. You get the findings whether or not you hire us, including the parts that are working.
- 02
Plan
Ecommerce PPC strategy agreed in writing, covering campaign structure, feed priorities, brand spend decision and the margin targets we will manage against.
- 03
Build
Feed fixed first, then structure, then bidding. Ads pointing at a broken feed or a slow landing page waste budget regardless of how well they are managed.
- 04
Launch
Changes rolled out in stages with performance monitored against contribution margin, and monthly reporting that leads with blended numbers.
Why Techzenix
Why brands choose Techzenix.
We fix the feed before touching bids
Shopping performance is decided in Merchant Center. Most ecommerce PPC companies never open it.
We split brand out on day one
Until brand spend is separated, no number in the account means anything.
We report blended, not platform
One figure for what a customer costs across everything, and one for what that customer contributes after all costs.
Pricing
What ecommerce PPC management costs with Techzenix.
$8,000$150,000
At $40,000 a month, a percentage model costs $5,500 more — and gets more expensive every time it spends more of your budget.
Book a 30 minute account review →- Management starts at $2,500 per month as a flat fee.
- Larger accounts are priced by catalogue and channel complexity rather than by spend.
- Standalone account and feed audits start at $1,800.
- Ad spend is paid directly to the platforms, never through us.
Straight talk. We are a poor fit for stores spending under roughly $8,000 per month on ads, where a flat management fee is difficult to justify. A one off audit and a feed cleanup usually returns more at that level.
FAQ
Ecommerce PPC FAQs
An ecommerce PPC agency manages paid advertising for online stores, covering Google Shopping, Performance Max, search and paid social, plus the product feed that Shopping serves from. The difference from a general PPC agency is feed expertise and margin literacy, because ecommerce runs on thin contribution margins.
Most ecommerce PPC companies charge either a flat monthly fee, typically $1,500 to $6,000, or a percentage of ad spend, usually ten to twenty percent. Percentage pricing creates an incentive to increase your spend. Ask which model an agency uses before comparing prices.
It is incomplete and double counted rather than wrong. Every platform claims credit for conversions it touched, so the totals overlap and exceed real revenue. Blended return, meaning total revenue divided by total spend, cannot be inflated the same way and should be your headline number.
Sometimes, but it should be a deliberate decision rather than a default. Brand clicks convert well and inflate reported performance while often replacing organic visits you already had. The honest test is whether pausing brand campaigns reduces total revenue, and it is worth measuring.
An ecommerce PPC consultant fits when you have someone running the account day to day and need strategy and oversight. An agency fits when you need the management as well. For stores under a certain spend, a consultant plus an audit is often better value.
Yes. Shopify PPC management benefits from straightforward catalogue and conversion tracking, which means more of the work goes into feed quality and campaign structure. The principles are the same across platforms but the setup differs.
