An ecommerce founder asks three agencies for a proposal and gets back $2,500, $7,500, and $18,000 a month. All three promise Meta, Google Shopping, email, and "scalable growth." The gap is rarely the channel list. It is how the fee is calculated, how much ad spend it assumes, whether creative is included, and whether anyone will judge the work on contribution margin instead of platform ROAS.
This is what ecommerce marketing actually costs in 2026, what each band buys, how the common fee models compare, what acquisition should cost against your margins, and how to read the quote in front of you.
The first question: what is inside the number?
Before comparing two proposals, ask for four lines in writing:
- Agency fee - strategy, campaign management, feed management, and reporting labor.
- Media spend - what goes to Meta, Google, TikTok, Amazon, and any other platform, billed to your own card in accounts you own.
- Creative production - static ads, video, UGC, photography, and landing pages. In ecommerce this is often the largest hidden cost.
- Retention and software - email and SMS platform fees, review apps, attribution tools.
A $7,500 quote that includes creative and email is a different engagement from a $7,500 media management fee with creative billed per asset. If a proposal will not split those lines, the monthly report will be just as hard to read.
How ecommerce agencies charge
Ecommerce pricing is less standardized than local services. These are the models you will see most:
| Model | Typical range | Watch for |
|---|---|---|
| Flat monthly retainer | $3,000-$15,000 | Fixed scope while spend grows. Confirm what happens to the fee when budget doubles. |
| Percent of ad spend | 10-20% of media, often with a $2,500-$5,000 minimum | An incentive to raise spend whether or not margin follows. Rates should step down as spend rises. |
| Hybrid (base plus percent) | $2,000-$5,000 base plus 5-10% of spend | Usually the fairest for growing brands. Check where the tiers break. |
| Performance or revenue share | 3-10% of attributed revenue, or a bonus on targets | Attribution games. Platform-reported revenue double counts. Tie it to blended numbers you control. |
Retention work is often priced separately. A dedicated email and SMS agency typically runs $2,000-$6,000 a month for strategy, design, flows, and campaigns, plus platform fees that scale with list size.
Budget bands by revenue stage
Monthly, agency fees only. Media and platform fees sit on top:
| Brand profile | Agency fees / mo | Typical media / mo | What it realistically covers |
|---|---|---|---|
| Early stage, $200K-$1.5M revenue | $3,000-$5,000 | $5,000-$25,000 | Meta and Google Shopping foundations, feed cleanup, core email flows, basic creative testing |
| Mid-market, $1.5M-$8M | $5,000-$10,000 | $25,000-$150,000 | Multi-channel paid media, structured creative testing, email and SMS campaigns, blended MER reporting |
| Scale, $8M-$20M+ | $12,000-$15,000+ (often split across specialists) | $150,000+ | Channel specialists, incrementality testing, feed optimization at scale, loyalty and retention architecture |
Creative is the line most founders underbudget. Plan on $1,500-$5,000 a month for a steady flow of new ad concepts at early stage and $5,000-$20,000+ at mid-market and above, whether it comes from the agency, freelancers, or UGC creators. Paid social fatigues fast without it.
As a planning figure, many DTC brands spend 10-25% of revenue on total marketing, with newer brands at the top of that range while they build a customer file and established brands lower because repeat revenue carries more of the load.
What acquisition should cost against your margins
There is no universal "good CPA" in ecommerce. The right number comes from your own contribution margin. Do this math before you take a meeting:
| Metric | How to calculate | What it tells you |
|---|---|---|
| Contribution margin per first order | AOV minus COGS, shipping, payment fees, and returns | The most you can spend to acquire a customer and break even on order one |
| Blended MER | Total revenue divided by total marketing spend | Whether the whole program is working, regardless of which platform takes credit |
| New customer CAC | Total acquisition spend divided by new customers | The honest cost of growth, stripped of repeat buyers |
| CAC payback | Months of contribution margin needed to recover CAC | How much cash growth will tie up |
Rough bands to sanity-check a plan: many healthy DTC brands run a blended MER of 3-5x, and brands with strong repeat purchase can accept first-order losses if CAC pays back inside 3-6 months. Brands with one-time purchases and thin margins cannot.
Any agency that reports platform ROAS without blended MER and new customer CAC is grading its own homework. Meta and Google both claim credit for the same orders.
What a cheap quote leaves out
Below about $3,000 a month in agency fees, something gets cut. Usually one or more of these:
- No creative pipeline. The same handful of ads run until performance decays.
- No feed management. Shopping and Performance Max are only as good as the product titles, images, and attributes in the feed.
- No retention program. All budget goes to acquisition while email and SMS, the cheapest revenue you have, sit on default flows.
- No margin-aware reporting. Revenue and ROAS without COGS, shipping, and returns.
- Ad accounts owned by the agency. If you do not own the accounts, pixels, and catalogs, you lose the data when you leave.
Cheap is not automatically bad. Cheap and opaque is.
Where the money should go by stage
Early stage: one or two acquisition channels done well, a clean product feed, welcome, abandoned cart, and post-purchase email flows, and a steady flow of new creative. Skip influencer programs and complex attribution tools you do not yet have the data to use.
Mid-market: structured creative testing, SMS alongside email, a second acquisition channel, and reporting on blended MER and new customer CAC every month. This is where a hybrid fee often makes the most sense.
Scale: the constraint usually shifts to inventory, cash flow, and creative volume. Money starts earning more in incrementality testing, retention and loyalty, and channel specialists than in another 10% of prospecting spend.
When not to hire an agency yet
- Revenue is under about $200K a year, or ad spend under $5,000 a month. The fee will eat the margin. Run one channel yourself and learn what converts.
- You do not know your contribution margin. Without it nobody can set a sane CAC target, and scaling spend can quietly lose money.
- The product page does not convert. If organic and email traffic convert poorly, paid traffic will too. Fix the offer, reviews, and page first.
- Inventory cannot support growth. Stockouts waste every dollar spent to drive demand.
- You cannot fund creative. Paid social without a creative budget is renting fatigue.
The short version:
- Separate agency fee, media, creative, and retention before comparing any two quotes.
- Know the fee model: flat retainer, percent of spend, hybrid, or performance. Make sure the agency's number moves with your margin, not just your spend.
- Expect $3,000-$5,000 a month in agency fees at early stage, $5,000-$10,000 at mid-market, and $12,000-$15,000+ at scale, plus media and a real creative budget.
- Set CAC targets from your own contribution margin. Judge the program on blended MER and new customer CAC, not platform ROAS.
- Own your ad accounts, pixels, and catalogs from day one.
