Shopify-Adsolut Inventory Synchronization

Job ID: 39764396

Budget: €750 – €1,500 EUR

Project to connect shopify environment with local invoicing system called Adsolut (wolters kluwer).
Goal is to keep the stock in Adsolut up to date when there is an order in shopify.
Same goes for other direction. When product is sold onsite at the shop, Shopify stock needs to be updated as well.

Some key point.
Adsolut invoicing application is a native app. Very limited access.
Database is running on a local terminal (master PC), other pc's are connecting to this environment via LAN.
The amount of products and thus stock will be very limited in Shopify. So only the matching product names needs to be synced
eg 100 products on shopify vs 5000 products in adsolut environment.

Connector Service (Node.js/TypeScript)
Hosts webhook endpoints for Shopify (orders, refunds, inventory events)
Pulls Adsolut stock deltas via SQL (Change Tracking / trigger queue)

Pushes stock updates + product mappings to Shopify Admin API
Runs on your local server next to Adsolut and optionally exposes outbound HTTPS via reverse proxy or tunnel (e.g., Nginx + Cloudflare Tunnel)

All other recommendations are welcome
