Shopify Inventory App Integration

I have an existing Shopify store and now need a smooth, no-drama integration with an inventory-management app. I’m not touching the theme or rebuilding the shop—this job is strictly about plugging in the right solution so I can press a simple button and instantly see current stock levels for every SKU.

Here’s what matters to me:
• A Shopify-approved inventory tool (Stocky, TradeGecko, Skubana, or any option you recommend) fully connected to my store.
• A clear “show inventory” button or similar UI element that reveals real-time stock data wherever we decide it’s most useful—product page, admin, or both.
• Zero disruption to checkout, payments, or my existing apps.
• Clean documentation so I can maintain the setup, plus room to expand later into automated re-ordering and alert features.

Deliverables
1. Advise on the most suitable inventory app for my requirements.
2. Install, configure, and test it in a duplicate theme before going live.
3. Implement the stock-display button and confirm it pulls accurate real-time data.
4. Provide a concise hand-off guide.

Please outline your estimated timeline and link to at least one Shopify inventory integration you’ve completed. Experience with the Shopify Admin API, ScriptTag injections, or Polaris UI components will help your proposal stand out.
