Adopt Core SaaS + Bespoke Integration Layer
Procure standard off-the-shelf software for commodity workflows (e.g. CRM, accounting, ticketing) and engineer a dedicated integration service to govern your unique business rules.
Immediate Execution Milestones
- Select mature SaaS platforms with well-documented REST/GraphQL APIs and webhooks.
- Define a central data synchronization contract to prevent duplicate records.
- Build a lightweight serverless middleware or integration service (e.g. Next.js Route Handlers, Node, or Cloudflare Workers) for custom business validation.
- Establish automated integration tests to detect breaking vendor API revisions.

Frequently Asked Questions
When should a business choose a Hybrid approach instead of pure Build or Buy?
A Hybrid architecture is optimal when standard commodity SaaS platforms (such as Salesforce, HubSpot, or NetSuite) handle 60-80% of core records, but your unique business logic or legacy system integrations require a proprietary middleware layer.
How does this advisor calculate the confidence score?
The calculation is completely deterministic. It weighs 12 distinct operational and architectural inputs across 4 decision trajectories (Build, Buy, Hybrid, Automate). Points are awarded based on industry integration benchmarks, and the strategy with the highest normalized score is recommended.
Are there hidden software development costs I should consider in custom builds?
Yes. In custom software, initial development typically accounts for only 30-40% of the 3-year Total Cost of Ownership (TCO). Ongoing maintenance, security patching, hosting, and API version migrations represent the remaining 60-70%.
Can Robonom help implement the recommended architecture?
Yes. Robonom designs and builds turnkey software solutions, custom API integration middleware, and automated workflows. You can book an architecture review directly from this tool.
