Quick tips for choosing a provider

• Prefer a Moodle Certified Partner if you want guaranteed alignment with Moodle standards and priority access to Moodle support. (moodle.com)
• Ask for references and examples of similar projects (hosting scale, integrations, third‑party plugins).
• Confirm support SLAs, upgrade/migration process, security/compliance (especially if you handle student or employee data).

If you want, tell me: your budget, number of users, and whether you need hosting, custom plugin development, or integrations — I can shortlist 2–3 providers from the list and draft an RFP/email you can send.
