- Dedicated Internet Access (DIA): Bandwidth is exclusively yours with guaranteed speeds. Includes SLA with uptime and latency guarantees. Best for mission-critical operations, VoIP-heavy offices, and data-intensive businesses. Pricing: $300–$2,000+/mo.
Business Internet Pricing Tiers
| Business Size | Recommended Speed | Typical Cost | Best Option |
|---|---|---|---|
| Home Office / 1–5 employees | 100–300 Mbps | $50–$80/mo | Comcast Business, T-Mobile |
| Small Office / 5–20 employees | 300 Mbps – 1 Gbps | $80–$200/mo | AT&T Business Fiber, Spectrum |
| Mid-Size / 20–100 employees | 1–5 Gbps | $200–$500/mo | Verizon Business, Frontier |
| Enterprise / 100+ employees | 5–10 Gbps DIA | $500–$2,000+/mo | Lumen, AT&T Dedicated |

Frequently Asked Questions
What is the best internet provider for small businesses?
Comcast Business and AT&T Business Fiber are the best options for small businesses in 2026. Comcast Business starts at $50/mo with wide cable coverage, while AT&T Business Fiber starts at $60/mo with faster symmetrical speeds. Both include 24/7 support and 99.9% uptime SLAs.
How much does business internet cost?
Business internet costs $50 to $200/mo for shared plans (cable or fiber) with speeds from 100 Mbps to 1 Gbps. Dedicated internet access (DIA) for enterprises costs $300 to $2,000+/mo depending on speed and SLA requirements. T-Mobile Business Internet offers the lowest starting price at $50/mo.
Do I need business internet or is residential enough?
Business internet is worth it if you need uptime guarantees, static IP addresses, priority support, or symmetrical upload speeds. Residential plans often have terms of service that prohibit commercial use, and they lack SLAs. For a home office with light usage, residential internet may suffice.
What internet speed does my business need?
A small office of 1–5 employees needs 100–300 Mbps. Offices with 5–20 employees using cloud applications and VoIP need 300 Mbps to 1 Gbps. Larger businesses with 20+ employees or data-intensive operations should consider 1 Gbps or higher dedicated connections.
What is a dedicated internet connection?
A dedicated internet connection (DIA) provides guaranteed bandwidth that is exclusively yours. Unlike shared cable or fiber, your speeds never fluctuate due to other users. DIA connections include SLAs guaranteeing uptime, latency, and packet delivery. They are ideal for businesses running VoIP, hosting servers, or processing large data transfers.

Business Internet vs. Residential Internet
While residential internet plans may seem cheaper, business internet offers several critical advantages that justify the higher cost for commercial use:
| Feature | Business Internet | Residential Internet |
|---|---|---|
| Uptime SLA | 99.9%–99.99% guaranteed | No guarantee |
| Upload Speeds | Symmetrical (same as download) | Typically 10–20% of download |
| Support | 24/7 priority with 4-hour response | Standard queue, business hours |
| Static IP | Included (1–5 addresses) | Not available or extra cost |
| Commercial Use | Allowed per TOS | Often prohibited in TOS |
| Data Caps | Typically none | Often 1–1.25 TB |
Industry-Specific Internet Needs
Healthcare and Medical Offices
Medical offices need HIPAA-compliant connections with strong security features, reliable uptime for electronic health records (EHR) systems, and adequate upload speeds for medical imaging. Recommended: 500 Mbps–1 Gbps dedicated fiber with static IP and encrypted VPN. AT&T Business Fiber and Lumen offer HIPAA-ready connectivity solutions.
Retail and Restaurants
Point-of-sale (POS) systems, inventory management, and customer WiFi all depend on reliable internet. A brief outage can prevent credit card processing and cost revenue. Recommended: 100–300 Mbps shared fiber or cable with a 4G/5G backup connection. Comcast Business and Spectrum Business offer POS-optimized packages with failover solutions.
Professional Services (Law, Finance, Consulting)
These offices rely heavily on cloud applications, video conferencing, and large file sharing. Upload speed is critical for firms that regularly upload documents, financial reports, or video depositions. Recommended: 300 Mbps–1 Gbps symmetrical fiber. Verizon Business and AT&T Business Fiber offer the most reliable professional-grade solutions.
Creative and Media Agencies
Video production, graphic design, and advertising agencies move massive files daily. A single 4K video project can be 50–500 GB. Recommended: 1–5 Gbps symmetrical fiber with no data caps. Google Fiber Business and Frontier Business Fiber offer the best value for high-bandwidth creative workflows.
Business Internet Redundancy and Failover
For businesses where downtime directly impacts revenue, consider a redundancy strategy:
- Dual-WAN Setup: Connect two different ISPs to a dual-WAN router. If one connection fails, traffic automatically routes through the backup. Cost: your primary plan + a secondary plan (often 4G/5G).
- 4G/5G Backup: T-Mobile Business Internet at $50/mo makes an affordable failover connection. Many business routers support automatic LTE failover.
- SD-WAN: Software-defined WAN intelligently routes traffic across multiple connections, improving both reliability and performance. Available from Comcast Business, AT&T Business, and Verizon Business at additional cost.
How to Order Business Internet
- Check availability: Enter your business address in our ZIP code lookup tool to see all available providers.
- Assess your needs: Count the number of employees, identify bandwidth-heavy applications (VoIP, video, cloud backup), and determine your uptime requirements.
- Request quotes: Contact 2–3 providers for pricing. Business plans are often negotiable, especially for multi-year commitments.
- Review the SLA: Ensure the SLA covers your uptime needs. Ask about credit policies for outages and response time guarantees.
- Plan for installation: Business fiber installation typically takes 2–6 weeks. T-Mobile business wireless can be set up in 1–2 days.

Business Internet Security Considerations
Business internet connections require stronger security than residential service. Here are the key security features to evaluate:
- Firewall and threat protection: Many business plans include managed security. Comcast Business offers SecurityEdge, AT&T provides ActiveArmor for Business, and Verizon includes BlueJeans security features. These protect against malware, phishing, and DDoS attacks at the network level.
- VPN compatibility: Ensure your business internet plan supports VPN connections for remote employees. Static IP addresses (included with most business plans) are required for site-to-site VPN configurations.
- Network segmentation: Business routers allow you to create separate networks for employees, guests, and IoT devices (security cameras, POS terminals). This prevents guest traffic from accessing your business systems.
- PCI compliance: Businesses that process credit card payments must meet PCI DSS requirements. Your internet connection needs to support encrypted transmission and network monitoring.
Common Business Internet Mistakes to Avoid
- Using residential service for business: Most residential TOS prohibit commercial use. If your ISP discovers business use, they may terminate your service. Business plans also lack the SLAs and support you need.
- Choosing the cheapest option: A $20/mo savings on internet is meaningless if a one-hour outage costs your business thousands in lost revenue. Invest in reliability.
- Ignoring upload speeds: Many businesses focus on download speed but upload is equally important for cloud backups, VoIP quality, and video conferencing. Choose symmetrical fiber when possible.
- No backup connection: A single internet connection is a single point of failure. Every business should have a backup plan, even if it is just a T-Mobile hotspot for emergencies.
- Forgetting scalability: Choose a provider that can increase your speeds as your business grows. Migrating to a new provider during a growth phase creates unnecessary disruption.
Business Internet Contracts and Negotiations
Unlike residential plans, business internet pricing is often negotiable. Here are tips for getting the best deal:
- Get multiple quotes: Contact at least 3 providers and share competing offers. Providers are more willing to match or beat a competitor's pricing.
- Negotiate term length: Longer commitments (2–3 years) typically come with lower monthly rates. However, ensure you can scale speeds within the contract period.
- Ask about installation fee waivers: Professional installation for fiber can cost $500–$2,000. Many providers waive this fee for multi-year contracts.
- Review auto-renewal terms: Many business contracts auto-renew at higher rates. Set a calendar reminder 90 days before expiration to renegotiate.
- Bundle services: Combining internet with phone, TV, or security systems often results in significant per-service discounts.
