Marketing Agencies — E-Commerce Developer

A senior e-commerce developer for marketing agencies

Marketing agencies sell outcomes, but their own operations are often the least systematised part of the business. Each client arrives with a different stack — one on HubSpot, one on Salesforce, one on a spreadsheet — and the agency absorbs that variety by hiring more account managers and building more one-off reports. Growth adds clients, but it adds the same amount of manual work, so margins flatten exactly when the agency looks busiest.

The second problem is proof. Retainers get questioned the moment results wobble, and an agency that cannot show, in the client's own numbers, what changed and why, is negotiating from weakness. Dashboards that nobody opens and monthly PDFs that nobody reads do not protect a retainer; a clear, shared record of work and results does.

An e-commerce developer builds the stores and checkout experiences marketing agencies sell through: storefronts, product and merch systems, subscription and pre-order logic, and the fulfilment connections that keep orders honest. Platform choice follows the business — Shopify, WooCommerce, or custom where the selling model genuinely needs it — and the build is judged on conversion and order accuracy, not on design awards.

What you get

What this engagement covers for marketing agencies

  • Storefronts built to convert — product pages, search, and navigation built around how your customers actually shop, with speed as a conversion requirement.
  • Checkout and payments — checkout flows, payment methods, and discount logic tested end to end with real scenarios, including failures.
  • Merch, bundles, and drops — product structures for variants, bundles, limited releases, and pre-orders, with inventory rules that prevent overselling.
  • Subscriptions and repeat purchase — subscription logic, renewals, and dunning handled properly, so repeat revenue does not leak on failed payments.
  • Fulfilment connections — warehouse, 3PL, and shipping integrations that keep stock, tracking, and customer updates in sync.
  • Post-purchase experience — order tracking, returns, and support flows that protect the second purchase, not just the first.
Working in Marketing Agencies

Built for how marketing agencies actually work

Tools and systems. The agency stack is well established, and builds must respect it. HubSpot and Salesforce cover CRM and marketing automation for most clients; reporting is assembled in AgencyAnalytics or Looker Studio; search work leans on Semrush and Ahrefs; paid media runs through Google Ads and Meta Business Suite; email through Mailchimp or the client's own platform; delivery is coordinated in Asana, Monday.com, or Slack. A new tool that duplicates one of these instead of connecting to it will be abandoned within a quarter.

Where the work pays off. The highest-value work is connective: a client onboarding flow that captures logins, brand assets, and goals once and provisions every system from it; a reporting layer that translates platform metrics into the client's business language; content and campaign workflows where approvals, publishing, and results live in one place; and a delivery record that makes the next quarterly review a conversation about results instead of a defence of the retainer. The agency's craft stays creative and strategic; the administration around it stops scaling linearly with headcount.

How it works

From kickoff to delivery

  1. Audit how you sell today

    Catalogue, checkout, fulfilment, and analytics reviewed, with conversion leaks identified before rebuilding.

  2. Choose the platform on evidence

    Platform picked from your catalogue, fulfilment model, and team's capability, not from preference.

  3. Build and test the buying journey

    Every path to purchase tested with real payment, shipping, and failure scenarios.

  4. Launch and watch conversion

    Go live with redirects and analytics, and monitor conversion and order accuracy in the first weeks.

FAQ

Questions, answered

Can you connect to each client's different stack?
Yes, that variety is the point. Builds use each client's existing CRM and ad platforms — HubSpot or Salesforce, Google Ads, Meta Business Suite, Mailchimp — through their official APIs, with a shared internal layer so the agency team works one way regardless of which client they are serving.
Will this actually protect retainers?
It gives the agency something a retainer review can stand on: a shared, current record of work delivered and results achieved, in the client's own metrics, updated without manual report-building. That does not guarantee renewal, but it removes the most common reason retainers are questioned — nobody could see the value.
How do you avoid adding yet another tool the team ignores?
By building into the tools the team already opens every day — Asana or Monday.com for delivery, Slack for approvals, AgencyAnalytics or Looker Studio for reporting — instead of launching a separate portal. Adoption is measured after launch, and anything unused gets cut.
Shopify, WooCommerce, or custom — how do you choose?
From your catalogue size, fulfilment model, customisation needs, and who will run the store day to day. The recommendation comes with the trade-offs stated, and the build follows the choice rather than the other way round.
Can you fix conversion on our existing store?
Often, yes. The audit separates quick conversion wins — speed, checkout friction, product-page clarity — from structural problems, and the plan is sequenced by expected return.
