|---|---|---|
| Service Level Agreement (SLA) | Guaranteed 99.9% uptime with bill credits for outages | No uptime guarantee — outages are handled on a best-effort basis |

Backup Internet for 100% Uptime
Even with a 99.9% SLA, your primary connection will go down eventually. These backup options keep your business running during outages:
T-Mobile Business Internet
$50/moPlug-and-play 5G backup. No installation, no contract. Keep it unplugged until your primary goes down, then switch over in seconds. Covers most TX metro areas.
4G LTE failover router
$150-300 one-time + $30-50/mo dataCradlepoint or Peplink routers auto-switch to cellular when your primary line drops. Zero downtime for your team. Best for businesses where every minute offline costs money.
Dual-WAN router with two ISPs
$100-200 router + second ISP planRun two different ISPs (e.g., AT&T Fiber + Spectrum cable) through a dual-WAN router. If one goes down, traffic shifts automatically. Most reliable option for critical operations.
Small Business Internet FAQ
Is business internet worth it for a small business?
Yes, if uptime matters to your revenue. Business plans include SLA guarantees (99.9% uptime), priority repair, static IP addresses, and symmetrical upload speeds. The cost premium over residential is typically $10-30/mo, which pays for itself the first time you avoid a costly outage during business hours.
Can I use residential internet for my small business?
Technically yes, but most residential terms of service prohibit commercial use. More importantly, you lose SLA protections, priority repair, and static IPs. If your business can tolerate occasional outages and does not need a static IP, residential internet works. For anything customer-facing, business plans are worth the premium.
Is business internet tax deductible in Texas?
Yes. Business internet is 100% deductible as an ordinary business expense under IRS Section 162. If you work from home, you can deduct the business-use percentage under the home office deduction. Keep your monthly statements as documentation. Texas has no state income tax, so this applies to your federal return.
What internet speed does a small business need?
It depends on your team size and usage. A 1-5 person office doing email, web browsing, and video calls needs 100-200 Mbps. A 5-20 person office with cloud apps, file sharing, and multiple video conferences needs 300-500 Mbps. If you run servers, handle large file transfers, or host video, get 1 Gbps fiber with symmetrical upload.
