Why We Don't Use Tiered Magento Support Packages

While other Magento agencies sell tiered Magento support packages, rigid Magento support plans and locked-in Magento support contracts to upsell premium features, we believe every client deserves the same senior Magento support service. One flat rate, one transparent contract, no artificial tiers.

Real Results for Real Businesses

Magento Support Response SLAs

Every Magento support retainer at Interjar includes the same response SLAs, regardless of monthly hours. No "premium tier" gating critical response.

  • P1 Critical

    15-minute response, 2-hour resolution target. Site down, checkout broken, payment gateway failed, security incident in progress. Senior developer paged immediately.

  • P2 Major

    2-hour response, same-business-day resolution. Single category broken, search not returning results, admin login broken, report failures. Active investigation begins inside the hour.

  • P3 Minor

    4-hour response, 2-business-day resolution. Cosmetic bugs, minor admin issues, single-product display problems, intermittent non-blocking errors.

  • P4 Scheduled

    Same-day acknowledgement, scheduled by sprint. New features, enhancements, content changes and planned development work. Estimate first, build second.

Magento Support FAQs

  • How quickly do you respond to support requests?

    We respond to all support requests within 2 hours during business hours. For critical issues affecting your live site, we provide emergency response and work to resolve them as fast as possible.

  • What's included in a Magento retainer?

    Everything. Unlike tiered packages that lock features behind higher price points, our retainers include bug fixes, new features, performance optimisation, security patching, and strategic advice, all at £100/hour, billed to the minute.

  • Can I change my retainer hours month-to-month?

    Absolutely. Our rolling 30-day contracts let you scale hours up during busy seasons, reduce them during quieter periods, or pause entirely. No penalties, no lock-ins.

  • How do you handle Magento security patches?

    We monitor for new Magento security releases and apply patches promptly through our automated deployment process. Every patch is tested in a staging environment before going live, ensuring zero-downtime updates.

  • Do you offer performance and conversion optimisation?

    Yes. Site speed improvements, checkout optimisation, and conversion rate analysis are all part of our standard support. We use tools like New Relic and Sentry to identify bottlenecks and measure the impact of every change.

  • What reporting do I receive?

    You get full visibility into exactly how your retainer hours are spent. Every task is logged with detailed time tracking down to the minute, so you always know where your budget is going.

  • Which versions of Magento 2 do you support?

    We support all Magento 2.x versions, including Magento Open Source and Adobe Commerce. We actively maintain stores on Magento 2.4.7 and 2.4.8, manage upgrades from older 2.x versions, and support Adobe Commerce Cloud deployments.

  • Is Magento 2 support different from Magento 1 support?

    Yes. Magento 2 uses a completely different architecture: Composer-based dependency management, modern PHP, and Elasticsearch for catalog search. Our team specialises in Magento 2's deployment pipeline, module management, and performance tuning stack.

  • What is the difference between Magento support and Magento maintenance?

    We use the terms interchangeably. A Magento maintenance retainer covers security patching, extension updates, bug fixes, performance monitoring and developer time for small changes.

  • Do I need a minimum number of hours per month?

    No. Our retainers have no minimum. You pay for the time you use at £100 per hour and unused hours do not expire at the end of the month.

  • How quickly do you respond to Magento emergencies?

    Critical issues like a store outage or broken checkout are responded to within 15 minutes during UK business hours. Our emergency support service is available separately.

  • Can I cancel the retainer at any time?

    Yes. All our agreements are 30 day rolling with no lock-in. If you want to stop using us you give 30 days notice and we hand over all code, credentials and documentation.
