Custom ecommerce systems for growing brands

Shopify works. The systems around it should too.

We build the automations, integrations, dashboards, and internal tools growing ecommerce brands need—without making them hire an engineering team.

Fixed project pricing · Clear technical ownership · No mandatory retainer · No lock-in

What we build
  • Operations automation
  • Inventory and fulfillment workflows
  • Support triage with human review
  • Cross-platform dashboards
  • Shopify integrations
  • Custom internal tools
We scope the result, build it, train your team, and leave you in control

Senior technical ownership

The technical team for brands that have outgrown apps and spreadsheets.

Most growing ecommerce brands do not need a full engineering department. They need senior technical ownership: someone who can understand the business problem, work across Shopify and the rest of the stack, and stay accountable through launch.

Operations automation

Order and fulfillment workflows, inventory operations, support triage with human review, team scorecards, and repetitive internal processes.

Data and decision systems

Profitability and KPI reporting, cross-platform dashboards, executive reporting, forecasting, and operational visibility that replaces manual spreadsheet work.

Custom commerce engineering

Shopify integrations, customer-facing operational tools, internal applications, custom data pipelines, and AI-assisted workflows with appropriate approval points.

Experience you can trust

Founded by brothers. Backed by real operating experience.

Parker and Taylor founded Miller & Miller. Their names are on the company, and its reputation is tied to the work.

Parker Miller
Parker MillerCo-founder

Parker brings operating experience from Google and Spot AI, plus a Stanford law degree.

That experience shaped Miller & Miller's approach to prioritization, risk, and measurement: separate useful systems work from expensive distraction.

Taylor Miller
Taylor MillerCo-founder

Taylor's background is in hands-on ecommerce implementation inside Shopify and the tools growing brands already use.

His focus on testing, documentation, and practical handoff helped shape a core company rule: clients should not be left with a black box.

Start with the $2,500 Kickstart—10 business days after kickoff and required access to a ranked roadmap, one tightly scoped proof build, training, and handoff.

A family business

Our name is on the company. Our reputation is in the work.

Miller & Miller was founded by brothers Parker and Taylor Miller. We built it to be the kind of technical partner we would want in our own business: experienced, clear, and accountable.

The company brings experience from Google, Spot AI, Stanford Law, and hands-on ecommerce implementation to its work.

Our name is on it. The standard is simple: tell clients what is worth doing, what is not, and stand behind the delivered system.

From a client

“These guys have been awesome — I can't recommend them enough. Unlike other contractors I've worked with, Miller & Miller came in with the goal for us to not need them. They rebuilt our software, cutting old software costs, and built new dashboards that give my team data at their fingertips. And they've improved our conversion rate and site speed like crazy — building UX we can A/B test, and building it fast.”

How the engagement works

Clear decisions before code.

The Kickstart establishes the opportunity. Every custom implementation then moves from a written result to a tested system and a clean handoff.

  1. 01

    Understand the operation

    Talk with the people who run the workflow and identify where time, money, or reliability is being lost.

  2. 02

    Prioritize the opportunities

    Rank potential work by expected impact, confidence, effort, dependencies, and operational risk.

  3. 03

    Agree on the result

    Define the scope, fixed price, and written acceptance criteria before implementation begins.

  4. 04

    Build and launch

    Implement, test, document, train the team, and put the system into production.

  5. 05

    Hand over control

    Your team can operate the system without an ongoing Miller & Miller contract. Another project and Care remain optional.

Pricing and engagement model

A clear starting point. A fixed price before we build.

Every company has a different stack, workflow, and amount of cleanup. We publish the starting point so you can judge fit, then scope each implementation around the actual business problem.

Kickstart

$2,500 fixed

Ten business days to identify, rank, and prove the best opportunities in your operation.

  • Interviews with the people who run the work
  • Top five opportunities ranked by impact, confidence, effort, and risk
  • Plain-English findings and recommended order
  • One tightly scoped proof build
  • Team training and handoff

Apply the full $2,500 to a qualifying custom implementation of $15,000 or more scoped within 60 days.

Start the Kickstart

Custom builds

Starting at $7,500

Once the workflow, systems, data, and acceptance criteria are clear, you receive one fixed project price before work begins.

  • Focused implementations begin at $7,500
  • Exact pricing determined case by case
  • Written scope and acceptance criteria
  • Larger work delivered through separately approved phases
  • Training, documentation, and a clean handoff
  • No mandatory monthly contract

The starting price applies to tightly scoped work with usable data, available access, and no major migration or cleanup.

Discuss a build

The Kickstart stands on its own. Continue only when the next project has a clear business case.

Optional monthly Care

Starting at $400/month

For business-critical systems you want us actively watching. Your team can operate the build without Care; the plan adds monitoring, platform-change reviews, and priority incident response.

  • Monitoring and relevant failure alerts
  • Next-business-day incident acknowledgement
  • Quarterly dependency and platform review
  • Up to one hour of minor corrective maintenance per calendar quarter
  • Cancel anytime

Coverage starts with one defined, low-complexity production system. Additional or more complex systems are quoted separately. New features and substantial platform changes are scoped separately.

Choose the model that fits the work

A focused technical team and an ongoing agency solve different problems.

Miller & Miller is built for a defined operational result, clear technical ownership, and a clean handoff. An ongoing agency model can be the better fit when the work is a continuous, cross-functional backlog.

Operational symptoms

The cost of a broken process compounds every month.

It is rarely just one software bill. It is the subscriptions, manual work, errors, slow decisions, and lost capacity around the workflow.

Current friction

What growing brands live with

  • Reporting assembled manually across Shopify, advertising, and email systems
  • Support teams answering the same operational questions repeatedly
  • Inventory and fulfillment work held together by spreadsheets
  • Important data trapped in tools that do not communicate
  • Founders acting as the integration layer between departments
  • Several subscriptions covering pieces of one broken workflow

With a well-built system

What changes

  • One reliable view of the operating metrics that matter
  • Repetitive requests routed or drafted with human control where needed
  • Inventory and fulfillment steps triggered consistently
  • Cleaner data moving between the tools the team already uses
  • Less founder and operator time spent reconciling systems
  • A clear before-and-after measure for the selected workflow
