Enterprise SaaS Marketplace Development

I’m building a multi-service, on-demand marketplace delivered as a SaaS platform and targeted at large enterprises. The application must be truly multi-tenant so each corporate client can manage its own environment while sharing the same codebase.

Core modules I need you to deliver:
• User management – fine-grained roles, SSO options, profile administration and the ability to onboard thousands of users per tenant without performance drops.
• Payment processing – secure, PCI-compliant flows that can route split payments to multiple service providers, support refunds, and expose clear reconciliation reports.
• Reporting & analytics – real-time dashboards and exportable reports that track transactions, user engagement and service performance across all tenants.

I expect clean, well-documented code, automated tests, and deployment scripts so the platform can move from staging to production smoothly. Please outline the tech stack you propose, any past SaaS marketplace experience, and an estimated timeline for an MVP followed by the full release.
