How to Transform from SI to SaaS: 2026 Government Policies and Practical Strategies

The Limits of the SI-Centric Market

The Korean IT industry has long grown around SI (System Integration). However, this model is hitting structural walls.

High upfront costs: Average SI projects run from hundreds of thousands to millions of dollars, creating steep entry barriers for SMBs

Extended timelines: From requirements analysis to delivery, projects take 6 months to 2 years, making it hard to keep pace with market changes

Vendor lock-in: Organizations become dependent on the original builder for maintenance, with costs compounding year after year

Technical debt: Legacy code accumulates, making new features and system scaling progressively harder

These issues affect SI companies too. Project-based revenue is volatile, and heavy reliance on labor makes it difficult to improve margins.

2026 Government SaaS Promotion Policies

The Korean government has recognized these structural challenges and is actively driving SaaS adoption.

Key Policy Directions

10,000 SaaS companies by 2030: The government is providing R&D funding and vouchers to nurture 10,000 domestic SaaS companies

Separate SaaS procurement in public projects: Public IT projects that were previously awarded as monolithic SI contracts now require SaaS components to be procured separately, opening the door for smaller SaaS providers

Cloud-native transition support: Consulting and migration subsidies for organizations moving from on-premise to cloud

SaaS quality certification: A dedicated SaaS certification program, distinct from the existing GS certification, gives bonus points for public sector adoption

These policies signal more than incremental support — they represent a paradigm shift from build-once (SI) to subscribe (SaaS).

SaaS Transition Checklist

Transitioning from SI to SaaS requires careful attention to both technical and business fundamentals.

1. Multi-Tenancy Architecture

Data isolation strategy: Shared database with schema separation vs. dedicated databases per tenant

Performance isolation: Ensure one tenant's workload doesn't degrade service for others

Customization boundaries: Clearly define what can be handled through tenant-level configuration versus code-level branching

2. Pricing Model Design

Usage-based: Charges proportional to API calls, storage, or transaction volume

Seat-based: Per-user pricing, the most common model in B2B SaaS

Feature-based: Tiered plans from Free → Basic → Pro → Enterprise

Start simple and iterate based on real customer data rather than over-engineering from day one

3. Onboarding Automation and Self-Service

Users should experience core value within 5 minutes of signing up

Auto-generated sample data, interactive guides, and ready-made templates

Self-service portals (knowledge base, video tutorials, FAQs) to reduce support costs

Stage-by-Stage Transition Roadmap

Stage 1: Cloud-Native Redesign of Core Features (3–6 months)

Extract the most universal, frequently used features from your existing SI product. Don't try to migrate everything at once — start with the 20% of features used by 80% of customers. Establish container-based deployment (Docker/Kubernetes), CI/CD pipelines, and Infrastructure as Code (IaC) during this phase.

Stage 2: Pilot Customers and PMF Validation (3–6 months)

Select 3–5 existing SI clients willing to participate in a pilot. Setting the monthly subscription at 30–50% of their current maintenance fees significantly reduces switching resistance. During this phase, closely track churn rate, feature adoption, and NPS.

Stage 3: Scale and Marketplace Listing (6+ months)

Once PMF is validated, ramp up marketing and list on platforms like Naver Cloud Marketplace, AWS Marketplace, and NHN AppBase. Actively bid on public SaaS procurement opportunities. At this stage, consider opening APIs and building a partner ecosystem.
