Ecommerce Growth Consultant for DTC Brands

Paid, CRO and retention run as one system and measured on profit — MER and contribution margin, not platform ROAS.

TL;DR

Ecommerce growth means scaling revenue without scaling losses. For DTC brands I run paid acquisition, conversion optimization and retention as one system, measured on MER, new-customer economics and contribution margin instead of platform ROAS. Engagements start from $3,500 a month; full-funnel ownership runs from $6,000 a month.

Revenue up, profit down

Many DTC brands hit the same wall. Revenue grows, ad spend grows faster, and at the end of the quarter there’s less cash than expected. Meta and Google both report strong ROAS, but they’re taking credit for the same customers, discounts are eating margin, and repeat purchase rates haven’t moved.

I run ecommerce growth on profit. Paid acquisition, conversion and retention are managed as one system, and every decision is judged on MER, new-customer economics and contribution margin.

How I grow DTC brands

1. Build the profit model

Product costs, shipping, fulfillment, payment fees, discounts and returns go into a contribution margin model by product and channel. It shows which products are worth advertising, what a new customer can cost, and how quickly they need to pay back.

2. Set targets that match the business

Blended MER, new-customer CAC, first-order contribution margin and payback period become the targets everyone works to. Platform ROAS stays an optimization input, not the scorecard.

3. Acquire profitably

Meta, Google Shopping, Performance Max, Search and TikTok, with server-side tracking and Conversions API feeding the algorithms clean purchase data. Creative testing runs on a fixed cadence, and spend is allocated according to what the profit model supports.

4. Convert more of the traffic

Product pages, collections, cart and checkout are improved through research and testing. Offer strategy — bundles, free-shipping thresholds, pricing and launches — is part of the work, because the offer often moves conversion more than the design does.

5. Retain and grow customer value

Klaviyo email and SMS flows, subscriptions with Recharge, post-purchase journeys, reviews and loyalty. Retention is what turns an expensive first order into a profitable customer.

6. Report profit weekly

One weekly report: revenue, spend, MER, new versus returning customers, contribution margin and what we’re changing next week.

When the store is the bottleneck

Sometimes the store itself holds growth back — a slow theme, a weak mobile experience, a checkout you can’t customize or a platform you’ve outgrown. In that case I rebuild or migrate it on Shopify as part of the engagement, with tracking and CRO built in from the start.

Where to start

Most brands start with the one-week Growth Audit. I review your store, ad accounts, tracking, email flows and margins, and deliver a first-pass profit model plus a ranked list of opportunities across acquisition, conversion and retention. From there we either run a focused scope — often paid media and retention first — or I take ownership of the full funnel as your fractional head of growth.

Who this is for

  • DTC brands with product-market fit and consistent monthly revenue, ready to scale spend profitably.
  • Shopify brands whose ad platforms report growth the bank account doesn’t reflect.
  • Founders running growth themselves who need a senior operator across paid, CRO and retention.

Who this is not for

  • Pre-launch brands still validating the product — start with a focused Shopify build and launch plan.
  • Brands looking only for a media buyer. This engagement owns the whole funnel and the margin.
Can built our Shopify stores and took the lead on growth marketing, and we started seeing strong results surprisingly quickly, making a noticeable difference to our online performance from the very beginning.

FAQ

Ecommerce Growth FAQ

What is MER and why use it instead of ROAS?

MER (marketing efficiency ratio) is total revenue divided by total marketing spend. Unlike platform ROAS, it can't be inflated by several platforms claiming the same sale, so it's a more honest measure of whether paid media is growing the business.

What is contribution margin?

Contribution margin is what's left from an order after product cost, shipping, payment fees, discounts and marketing. It shows whether growth is actually profitable, and it's the number I use to decide how much you can afford to pay for a new customer.

How much does ecommerce growth consulting cost?

Engagements start from $3,500 per month for a focused scope, usually one or two channels. Full-funnel ownership across paid, CRO and retention runs under Fractional Growth OS from $6,000 per month. Most brands start with the $1,500 Growth Audit, credited if we continue.

Do you only work with Shopify stores?

Most of my ecommerce work is on Shopify, and I also build and migrate Shopify stores. For growth work I also work with WooCommerce and other platforms, and I'll tell you honestly whether a migration is worth it.

What size of brand is this for?

Brands with product-market fit, consistent monthly revenue and a paid media budget they want to scale profitably. Pre-launch brands are usually better served by a solid Shopify build and a focused launch plan first.
