Selection criteria
A Shopify tool should solve a specific operating problem. Before installing another paid app, estimate the app cost per order and ask whether it improves conversion, retention, fulfillment, reporting, or margin enough to justify the cost.
Tool categories to evaluate
| Category | What it should help with | Margin question |
|---|---|---|
| Payments and checkout | Payment method selection, card rates, conversion, and checkout reliability. | Do fees and conversion gains justify the setup? |
| Shipping and fulfillment | Labels, rates, tracking, shipping rules, and fulfillment workflows. | Does it reduce shipping errors or improve delivery cost control? |
| Email and retention | Welcome flows, abandoned cart, repeat purchase, and customer education. | Can repeat purchase profit support acquisition cost? |
| Reviews and social proof | Collecting honest customer reviews and product questions. | Does conversion improvement exceed app cost? |
| Analytics and attribution | Tracking revenue, margin, CPA, ROAS, cohorts, and refund impact. | Can you trust the data enough to make ad decisions? |
| Inventory and product operations | Stock levels, bundles, purchase planning, and landed cost visibility. | Are stockouts, waste, and reorder mistakes hurting margin? |
