Shopify development retainer. Buy a block of hours, not a project.

A Shopify retainer is a pre-paid monthly block of senior engineering hours used for in-life storefront work rather than a discrete project. Typical retainer work includes new Liquid sections, app integration, Core Web Vitals remediation, accessibility fixes, seasonal campaign pages, Klaviyo and Recharge debugging, and any small-to-mid change that does not warrant a fresh statement of work. Good retainers are hours-based, transparent, and priced the same whether the hours go into a single big ticket or twenty small ones.

US and UK boutique Shopify agency rates for senior engineers cluster between $150 and $250 per hour in 2026, with Shopify Plus specialists at the top of that range. Offshore and freelance rates run $30 to $80 per hour; mid-market Indian agencies, including us, sit around $75 to $125 per hour for senior work. A retainer reduces the effective rate versus pure hourly by blending senior and mid-level time, bundling project management, and amortizing Shopify Partner tooling across many merchants. Posted dollar rates are anchors, not contracts; the scoped quote follows an intro call.

A healthy Shopify store between $250K and $2M a year in revenue usually burns 10 to 25 engineering hours a month on in-life work. $2M to $10M brands trend toward 25 to 50 hours. Shopify Plus brands past $10M often sit above 50. The burn rises around campaign launches, Black Friday, platform updates, and app migrations. If you are hitting a 10-hour retainer ceiling every month, move up a tier. If you are rolling over more than 40% of hours two months in a row, move down.

Yes, up to a cap, for one month. Retainer 10 rolls up to 5 unused hours; Retainer 25 rolls up to 12; Retainer 50 rolls up to 25. Rolled hours expire at the end of the following month, not into perpetuity. The cap exists so the retainer stays a working relationship rather than an hour hoarding account; the rollover exists so a quiet month does not feel like money burned.

Nothing breaks. We flag the ticket that will push you past your block, you approve or defer, and overage hours are billed in 5-hour increments at the retainer's base rate. We never work silent overage. If overage becomes a pattern for two consecutive months, we move you to the next tier where the blended rate is lower.

The agreement is 30-day rolling. You can cancel, pause, or downgrade with 30 days' notice for any reason. There is no twelve-month lock-in, no exit fee, and no proprietary dashboard you lose access to. Rolled-over hours remaining at cancellation are either worked before the close date or refunded at the retainer's base rate, your choice.

Pure hourly fits a one-off question or a single two-hour fix; it is priced higher per hour because it bundles no continuity. A project fits a defined outcome with a deadline, like a theme rebuild or a checkout extension migration. A retainer fits everything in between: steady small-to-mid work, seasonal bursts, app integration, and the kind of changes you want shipped this week without scoping a fresh SOW. Most Shopify brands past $500K a year run a project plus a retainer, not one or the other.

Four priority levels, four response SLAs, published on every invoice. P1 store-down or checkout-broken: 30 minutes to 1 hour depending on the tier. P2 revenue-impacting but not store-down: 4 hours. P3 standard feature work: 1 business day. P4 nice-to-have and cosmetic: 3 business days. Response is acknowledgement plus an estimate; resolution follows the ticket's hour budget. SLA adherence is reported every month.

You do, on day one and on exit. The theme repo is under your GitHub organization. Linear tickets can be exported as CSV on request. Time logs are sent month-end in CSV plus PDF. Slack Connect channel remains yours to archive. We do not hold assets, dashboards, or ticket history to force renewal. If the retainer is the right fit, you will renew because the work is good, not because the code is hostage.

Yes, and sometimes that is the correct answer. A senior Shopify freelancer costs less per hour than an agency retainer but carries three risks: single-person dependency (illness, holidays, churn), no SLA, and no named backup for critical incidents. A retainer costs more per hour but buys redundancy, tiered response time, and a named project manager who sees your queue without you chasing. Stores that run a single external engineer for more than a year usually convert to a retainer after a BFCM outage; the math compounds after the first P1 incident where nobody answered.
