Growth Retainers

A dedicated team, month after month

What we offer

Ongoing Shopify development and optimisation from a team that knows your store inside out.

The best Shopify stores aren't built once. They're iterated on continuously: new features, CRO experiments, performance improvements, platform updates. A growth retainer is how that happens without the overhead of managing a new project every month.

You get a dedicated developer and strategist who know your codebase, your customers, and your commercial goals. We just get on with the work.

What's included

Everything in the retainer

Dedicated developer

A senior Shopify developer assigned to your account. They know your codebase, your stack, and your team, so there's no briefing from scratch every month.

Monthly CRO reviews

Regular conversion rate optimisation reviews using your analytics, heatmaps, and session recordings. Data-driven recommendations, not guesswork.

A/B testing

Structured experiments with statistical rigour. We design the test, implement it, call it when it's significant, and roll out the winner.

Priority development

Fast turnarounds on development tasks without the overhead of quoting every job. A committed monthly allocation you can use flexibly across any type of work.

Quarterly strategy

Quarterly strategy sessions to review performance, align on goals, and plan the next quarter's work. A dedicated conversation about the bigger picture.

Technical oversight

We review app additions, third-party integrations, and platform changes before they go live, protecting performance and avoiding technical debt.

Content production

In-house ecommerce copywriting available as a retainer component — category page copy, product descriptions, and seasonal content that builds organic traffic over time.

Why it works

What you get

A team that knows you

Retainer clients don't brief us from scratch each month. We know your store, your stack, your preferences, and we move faster because of it.

No admin overhead

No quotes, no scope documents, no project kickoffs for small jobs. A monthly allocation you use for whatever needs doing, and we just get on with it.

Continuous improvement

The best Shopify stores aren't built once and left. They're iterated on constantly: CRO, performance, new features, platform updates. A retainer is how that happens.

Commercial alignment

We're incentivised by your growth, not by billing hours. Our CRO reviews, A/B tests, and development priorities are all pointed at the same goal: more revenue.

Platform updates handled

Shopify changes constantly. Theme editor updates, new API versions, checkout extensions: we track what's relevant to you and handle it proactively.

Faster to market

When you have an idea or a seasonal campaign, it ships fast. No procurement cycle, no new agency brief. Just a message to a team that already knows your store.

How it works

Getting started

01

Onboarding audit

We audit your Shopify store thoroughly, covering code quality, performance, analytics setup, conversion funnel, and app stack. You get a clear picture of where you are before we start improving it.

02

Priority roadmap

Based on the audit, we build a prioritised roadmap for the first quarter. Quick wins identified, longer initiatives planned, and a shared view of what we're working towards.

03

Monthly rhythm

A steady monthly cadence: development work from the allocation, CRO review from your analytics, a short written update on what was done and what's next.

04

A/B testing programme

For Growth and Accelerate retainers, we run a continuous A/B testing programme, designing experiments, implementing variants, and calling results with statistical confidence.

05

Quarterly strategy

Every quarter, we step back from the execution and review performance against your goals. What's working, what to change, and what the next quarter's focus should be.

06

Ongoing optimisation

The retainer improves over time. We learn your business, your customers, and your priorities, and the work gets sharper and more impactful as a result.

FAQs

Common questions

What's included in the monthly allocation?

The allocation covers any Shopify development work: custom features, theme updates, app integrations, bug fixes, performance improvements, and A/B test implementation. You direct how it's used each month; we advise on priorities.

What if we don't use the full allocation one month?

Unused hours roll over to the following month (up to a cap, depending on the retainer tier). We'd rather you build up credit for a bigger piece of work than feel pressured to find things to fill the allocation.

How quickly do you respond to requests?

Retainer clients get priority response times, typically within a few hours during working hours for questions, and same-day starts for development tasks depending on the queue.

Do we need to be on Shopify already?

Yes. Retainers are for established Shopify stores. If you're migrating from another platform or launching fresh on Shopify, we'd typically start with a project engagement and move to a retainer post-launch.

Can we change retainer tier?

Yes. If your needs grow or contract, we can adjust the retainer up or down at a quarter's notice. We'd rather you're on the right level than paying for more than you need.

What does CRO actually involve month to month?

We review your Google Analytics (or equivalent), session recordings, and funnel data each month. We identify the highest-impact opportunities, prioritise them, and either implement fixes directly or add them to the A/B testing queue. You get a written summary of what we found and what we're doing about it.
