FAQ

Frequently asked questions.

What Drupal services does Drupallers offer?

Custom Drupal module development, Drupal theme development (including Acquia Site Studio), Drupal 7/8/9 → 10 migrations, headless and decoupled Drupal builds (React, Next.js, Vue), Drupal Commerce, multisite architectures, 24/7 support and maintenance, and AI-powered Drupal integrations.

Which Drupal versions do you support?

Drupal 7, 8, 9, 10, and 11 — including active Drupal 11 upgrades for clients moving off Drupal 10. We migrate older Drupal 7 estates straight through to Drupal 11 and keep mixed-version platforms in production safely. We follow Drupal core release cycles and apply security releases to active support clients within SLA.

Do you work with clients outside the USA?

Yes — actively working with clients across the USA, United Kingdom, Europe (including the EU), Canada, and Australia. Support coverage spans every major time zone.

Can you take over an existing Drupal site from another agency?

Yes. Agency takeovers are a common engagement — we begin with a full Drupal audit (security, performance, code quality, deployment process), provide a remediation roadmap, then either deliver fixes ourselves or hand back a clean baseline.

How fast can you start?

For audits and short engagements, typically within a week. For larger build engagements we'll scope, propose, and start a discovery sprint within 2–3 weeks of first contact.

Have a Drupal project in mind?

Tell us about the platform, the audience, and what success looks like. We'll come back with a clear scope, a realistic timeline, and a fixed price where we can.
