The E-Commerce Dilemma
You've decided to sell online. Now comes the big decision: do you use a ready-made platform like Shopify or Cafe24, or do you build a custom store from scratch?
Both approaches have been used to build billion-dollar businesses. The right choice depends on your specific situation.

The Breakeven Point
At approximately $500,000 in annual revenue, the transaction fees on SaaS platforms start to exceed the maintenance cost of a custom solution. At $1M+ annual revenue, custom development almost always provides better ROI.
A Hybrid Approach
Many successful businesses start on Shopify or Cafe24 to validate their market, then migrate to a custom solution as they scale. This approach:
Minimizes upfront risk during the validation phaseProvides real customer data to inform custom development decisionsGenerates revenue that funds the custom buildAllows gradual migration without disrupting salesConclusion
Start with a SaaS platform if you need to launch fast and validate your business model. Invest in custom development when your revenue justifies it and platform limitations start holding you back. POLYGLOTSOFT specializes in both SaaS-to-custom migrations and ground-up e-commerce development.
