| Option / Approach | Best When | Primary Tradeoff / Risk | Recommended Fit |
|---|---|---|---|
| Theme-Only Freelancer | Minor Liquid CSS tweaks or installing public apps | Cannot build custom Checkout UI Extensions, Functions, or middleware APIs. | Minor cosmetic tweaks |
| Stacking Public App Store Plugins | Early DTC stores under $20k/mo GMV | App script bloat slows storefront LCP/conversion and hits data-sync limits. | Early-stage starter stores |
| In-House Shopify Plus Engineer | Full-time 12+ month internal roadmap | 3–6 month hiring cycle and $130k+/yr salary overhead without QA or design bench. | Large enterprise brands ($20M+ GMV) |
