Frequently Asked Questions

Common questions about our maintenance and support services

What is the difference between L1, L2, and L3 support?

L1 handles basic user support like password resets and access issues. L2 covers technical troubleshooting including system diagnostics, configuration problems, and performance issues. L3 involves engineering-level support for complex code fixes, architectural improvements, and deep root-cause analysis requiring senior developer expertise.

What are your typical response times?

Response times depend on your SLA tier and issue severity. Critical issues (P1) typically receive a response within 15-30 minutes. High-priority issues (P2) are acknowledged within 1-2 hours. Standard issues (P3/P4) are responded to within 4-8 business hours. All response times are guaranteed in your SLA agreement.

How do SLA agreements work?

Our SLAs define guaranteed response and resolution times, uptime targets (typically 99.9%+), escalation procedures, and reporting cadences. We customize SLAs based on your business requirements and criticality of systems. Monthly reports track our performance against agreed targets.

How much does maintenance and support cost?

Pricing depends on the scope of support, number of applications, SLA tier, and support hours required. We offer flexible plans ranging from basic monitoring packages to comprehensive 24/7 support. Contact us for a tailored quote based on your specific needs and infrastructure complexity.

What is included in a standard support package?

A standard package includes 24/7 uptime monitoring, monthly security patches and dependency updates, bug fixing within SLA timeframes, performance optimization reviews, regular health reports, and a dedicated support channel. Feature enhancements and major upgrades can be added as needed.
