Challenge
After the successful launch of InvoiceFlow’s MVP, the startup lacked the in-house resources to:
- Maintain product stability under a growing user base
- Fix production bugs and hotfixes efficiently
- Continuously roll out enhancements and user-requested features
- Monitor security and performance vulnerabilities
- Set up proper CI/CD and QA workflows for future updates
Their goal was to ensure reliability and growth without building a full internal dev team.

Elyxtech partnered with InvoiceFlow in a long-term maintenance and development support engagement, focusing on 4 key areas:
1. Ongoing Maintenance & Monitoring
- Set up uptime monitoring, error logging (using Sentry), and performance tracking (via New Relic)
- Implemented version control workflows and standardized deployment with GitHub Actions
2. Bug Fixing & SLA-based Support
- Created a support queue with defined SLAs for critical, high, and low-priority issues
- Average bug resolution time: under 24 hours for critical issues
3. Feature Enhancements & Technical Upgrades
- Added high-priority user-requested features (PDF export, audit trail, batch processing)
- Performed regular dependency upgrades and framework updates without downtime
4. Security Patching & Performance Optimization
- Patched Node.js and npm vulnerabilities with monthly audits
- Optimized query performance and reduced API response times by 35%
Technologies Used
Results & Achievements

ModeLift’s internal team now uses our modular product page layout to launch campaigns faster with improved UX by default.
This case demonstrates how small, data-backed UX improvements can create massive business impact. By focusing on user behavior, A/B testing, and thoughtful UI design, Elyxtech helped ModeLift unlock real growth with no new traffic spend.
