For a non-profit organization (NPO) with 15 seats, your budget for Avaya will vary depending on whether you choose a modern Cloud solution (OpEx) or a traditional On-Premise system (CapEx).
In 2026, most NPOs favor Avaya Cloud Office, as it eliminates the need for expensive server hardware and maintenance.
1. Cloud-Based Budget (Recommended)
Avaya Cloud Office (powered by RingCentral) is the standard for small teams. For 15 users, you should budget between $3,600 and $5,400 annually for the service alone.
Annual Service Estimates (15 Seats)
| Plan Tier | Monthly per User | Total Annual Cost | Key Features |
| Core | ~$20 | $3,600 | Unlimited US/CA calling, SMS, and AI transcripts. |
| Advanced | ~$25 | $4,500 | Everything in Core + CRM integrations (Salesforce, etc.). |
| Ultra | ~$35 | $6,300 | Everything in Advanced + high-tier analytics and storage. |
Non-Profit Tip: While Avaya does not always advertise a standard “NPO” discount on its website, they often offer Education pricing (starting around $12.99/user) which they may extend to qualifying 501(c)(3) organizations. This could drop your annual budget to roughly $2,340.
2. Hardware Costs (One-Time or Rental)
You have three main options for the physical phones:
- Rental: Many Avaya plans allow you to rent desk phones for $5–$15/month per device. For 15 seats, this adds $900–$2,700 to your annual budget.
- Purchase: Basic IP phones (like the J139) cost roughly $150–$200 each.
- One-time cost: $2,250–$3,000.
- Softphone Only: $0. Your team uses the Avaya app on their existing computers or smartphones.
3. Implementation & Hidden Costs
Don’t forget to set aside a small “slush fund” for the first year:
- Setup Fees: Usually waived for 15+ seats, but budget $500 just in case for professional configuration.
- E911 & Taxes: Expect roughly 10-15% on top of your monthly bill for regulatory fees and taxes.
- High-Speed Internet: Ensure your office bandwidth can handle 15 concurrent VoIP calls (usually not an issue with modern fiber/cable).
Summary Recommendation
For a 15-seat NPO, a safe Year 1 Budget is $5,000. This covers:
- $3,600 for the Core service.
- $900 for a mix of taxes and a few hardware upgrades.
- $500 for initial setup/training.
