Once the MVP proves product-market fit, the work shifts to long-term builds: deeper features, enterprise contracts, integrations. Claude Code stays productive across that horizon; here is the playbook for months 2 through 18.

Updated: April 24, 2026

## Stabilize the foundation

Month 2 is about reducing noise. Standardize on a feature template (controller + service + repository + test), bake it into a slash command, and let Claude Code scaffold every new endpoint the same way. Code reviews drop from 40 min to 10.

## Layer in enterprise features

SSO, SCIM provisioning, audit logs, role-based access, data residency. Each of these used to be a 2-week project. With Claude Code plus a reference implementation MCP server, we ship them in 3 days.

## Integrations

Your B2B SaaS will need Salesforce, HubSpot, Zapier and a dozen industry-specific tools. Each integration is another MCP server away. Wrap the client's CRM API once, reuse across every future integration task.

## Frequently asked questions

### Does the quality hold for multi-year codebases?

Yes, if CLAUDE.md is kept current and the team enforces lint/test gates. We have projects running past month 18 where the agent still ships production PRs daily.
