What to Include in a Support Request

A complete support request helps the Sigma team investigate and respond faster. Include the following in every message:
  • Your clinic name and the email address associated with your Sigma account
  • A brief description of the issue or question — what you were trying to do, and what happened instead
  • Record reference numbers if your question relates to a specific billing or claims issue (patient reference, invoice number, or claim reference)
  • Screenshots or screen recordings if the issue involves unexpected system behaviour — visual context removes ambiguity and speeds up resolution
The more specific your request, the faster and more precisely the team can respond.

​
Response Times

Sigma operates across multiple time zones to serve clinics in Africa, Asia, and the Americas. Response times below apply to business days in your region.
  • Standard inquiries — email responses within 1 business day for general questions, configuration help, and billing inquiries
  • Urgent technical issues — if you are experiencing a platform outage, data access problem, or a blocking issue on go-live day, include “URGENT” in your email subject line to escalate your request for priority handling
  • Dedicated account managers — higher-tier subscription plans include direct access to a named account manager who can be reached by email or scheduled call
If you have not received a response within one business day for a standard inquiry, resend your email with a brief note. Response delays are uncommon but not impossible.

​
Book a Product Demo

A Sigma demo is a live, working walkthrough — not a slide deck. During the session, a Sigma team member will:
  • Walk through billing, claims, and payments using a representative sample clinic
  • Answer your questions about your specific insurer schemes and workflows — bring your real scenarios
  • Outline a setup timeline and onboarding plan sized to your clinic’s situation
  • Show you how the system handles the edge cases that matter to your team: rejected claims, partial payments, multi-site billing
To book a demo, visit sigmahmis.com/contacts or email hello@sigmaconnect.org with the subject line “Demo Request”. Include your clinic name, country, and a brief description of your current billing setup so the team can tailor the session.
When asking about a specific claim or invoice issue, always include the record reference number. It allows the Sigma team to pull up the exact record immediately and speeds up the investigation significantly.
