Monthly engineering for software already in production: maintenance, security updates, improvements, and reserved capacity. Essential Care from $4,000/month, Continuous Engineering from $5,000/month, Technology Partnership from $10,000/month.
Software that runs the operation does not stay healthy on its own. Ongoing Engineering is monthly engineering capacity for systems already in production — maintained, secured, improved, and evolved by the people who built them.
Three tiers, from $4,000/month. Starting at is the minimum qualifying scope, not the default quote.
Essential Care
$4,000/month
Keeping what is live healthy, current, and quietly monitored.
—Maintenance and application health monitoring
—Dependency and security updates, and security patching
—Basic vulnerability monitoring
—Backup and recovery checks where applicable
—Bug remediation and compatibility maintenance
—Small improvements
Continuous Engineering
$5,000/month
A steady stream of engineering capacity after implementation.
—Everything in Essential Care
—Feature development and integrations
—Proactive security hardening
—Recurring dependency, security and access-control review
—Integration-security maintenance
—Performance, architecture and optimization work
Technology Partnership
$10,000/month
Reserved capacity and senior technical direction over the long term.
—Threat-model updates and deeper access-control review
—Resilience and recovery planning
—Product strategy, AI and automation evolution
What an agreement defines
Capacity, response expectations, and scope — including security maintenance and any incident support for Birchline-maintained software — are defined in each agreement rather than promised as unlimited work.
Security is part of the engineering process, not an add-on after launch. We consider it during architecture, development, testing, deployment, and ongoing maintenance.
