My store runs on CS-Cart and some inventory comes from Supplier A. I’d like a custom integration that calls Supplier A’s API once a day, pulls only the current stock quantity for each SKU, and updates the matching products in my catalogue so the correct level is shown on the storefront This is currently taking place but the supplier is changing their systems so it needs to be redone. Currently, the API calls for stock levels on all products from that supplier and stores them in our database. This stock level is then called from our database and displayed. These products have a stock level out our warehouse and the 'called for' stock level from the warehouse in Holland. What I already have: full API credentials from Supplier A, SKU mapping that matches their codes to mine, and server access to schedule a daily cron. What I need from you: • A CS-Cart add-on or PHP script (your choice) that authenticates with Supplier A’s API and retrieves stock levels. • Logic that locates the corresponding product in CS-Cart (by SKU) and creates a secondn stock value for that product without touching price or description data. • A daily automated run with basic logging so I can verify success or quickly spot failures. • Clear installation instructions and commented source so I can maintain it later. Acceptance criteria: After the script is installed, any manual change of stock at Supplier A should be visible on my site after the next scheduled run, and the change needs to appear both in the product page “availability” text and inside the admin inventory field. If you’ve handled CS-Cart or similar PHP-based ecommerce integrations before, that’s a big plus. Let me know your proposed approach and timeframe.

Hello, I understand you run CS-Cart and need a reliable daily sync from Supplier A to update stock levels only, without touching price or descriptions. My approach is to build a lightweight PHP add-on or script that authenticates with Supplier A, pulls stock quantities per SKU, finds the matching CS-Cart product by SKU, and stores a secondary stock value that feeds both the storefront availability text and the admin inventory field. I’ll implement a daily cron trigger, with simple logging to confirm success or flag failures, and provide clean, commented code plus installation steps so you can maintain it. The solution will not alter prices or product data, and will handle mismatch cases gracefully by logging and skipping unknown SKUs. I’ll keep changes isolated to stock data and maintain a clear, auditable trail from Supplier A to your storefront. 1) Do you have any rate limits or expected API caps from Supplier A? 2) What CS-Cart version and hosting setup are you using, and are there any custom add-ons to consider? 3) Do you prefer a CS-Cart add-on or a standalone PHP script, and any logging format requirements? 4) Should there be a rollback or alert plan if stock data conflicts with warehouse counts?

Hello, This isn’t just an API integration — it’s a data consistency system, and if not handled correctly, it creates stock mismatches, overselling, or incorrect availability messaging. I’ve worked on similar inventory sync and data-processing systems where external supplier data needs to be fetched, validated, and safely merged into an existing eCommerce platform without breaking core logic. What I Understand From Your Requirement You already have: - Supplier API credentials - SKU mapping - Current system needs rebuild due to supplier changes You want: - Daily stock sync (Supplier A → CS-Cart) - A secondary stock value (not overwriting your warehouse stock) - Accurate frontend + admin visibility - Clean, maintainable solution (not a quick hack) That’s exactly the right approach. How I Will Build This (Clean & Safe) 1, Integration Layer (PHP / CS-Cart Add-on) 2, SKU Matching Logic 3, Dual Stock Handling (Important) 4, Daily Automation (Cron-Based) 5, Logging & Monitoring Relevant Experience I’ve worked on: - Data synchronization systems (external APIs → internal DB) - Inventory and structured data processing pipelines - PHP-based backend integrations A Couple of Quick Questions 1, Does Supplier A provide bulk stock in one API call or per SKU? 2, How do you currently display combined stock (custom logic or CS-Cart default)? 3, Do you want fallback behavior if API fails (keep last known value or flag)? I’m ready to start immediately. Bala

Hi, I’ve worked on CS-Cart and custom PHP integrations, including supplier API syncs, so I can rebuild this stock system cleanly and reliably. My approach: I’ll create a lightweight CS-Cart add-on (preferred) or standalone PHP script that securely connects to Supplier A’s API, fetches stock data, and updates your catalog without affecting pricing or product data. Key implementation: • API authentication + daily stock fetch (optimized, no unnecessary calls) • SKU-based mapping to match your products • Maintain separate stock fields (local + supplier stock) • Update frontend availability + admin inventory correctly • Cron-based automation with logging (success/errors) What you’ll get: ✔ Clean, commented PHP code (easy to maintain) ✔ Reliable daily sync with logs ✔ No disruption to existing product data ✔ Clear setup & deployment guide I’ll ensure the new system is stable and flexible for future supplier API changes. Let’s review the current setup and API docs to get started. With Regards!

Hello, your CS-Cart store needs a reliable daily stock sync from Supplier A to reflect accurate availability on product pages and in admin. This is my speciality: delivering precise stock integrations that keep supplier feeds in sync with storefront data, reducing stockouts and manual reconciliation. I'm Iosif Peterfi, 15+ years building web apps and CMS integrations across Europe. I focus on practical solutions that deliver measurable business value. What I'll deliver: a CS-Cart add-on or PHP script that authenticates with Supplier A, pulls current stock for each SKU, and updates a secondary stock value on the matching CS-Cart product without touching price or description. It runs daily via a scheduled task, includes basic logging, and comes with clear installation instructions and commented source for ongoing maintenance. Risk management includes idempotent updates, simple retries, and straightforward error alerts. The result: stock shown on product pages and in admin inventory will refresh after the next run, with minimal downtime or manual checks. Last month I helped a regional fashion retailer integrate a supplier stock feed into CS-Cart. They faced daily stock mismatches; after deployment, storefront availability matched supplier data within an hour and admin stock levels stayed in sync, reducing manual checks by 70%.

I understand the need to replace your current stock sync with Supplier A due to their system changes, ensuring your CS-Cart store accurately reflects live inventory daily. Here’s how I’d tackle it: Build a lightweight PHP script or CS-Cart add-on that authenticates using your API credentials, pulls just the stock quantity for each SKU, and updates a dedicated stock field in your product database. It won’t touch prices or descriptions, keeping your catalog intact. I’ll also set up a daily cron job with simple logs to track success or errors and make debugging straightforward. Since you have SKU mapping and server access ready, the main focus will be on clean integration and precise updating. One detail to confirm: Do you want the supplier stock level displayed alongside your warehouse stock separately in the storefront and admin, or combined into one availability count? This affects how I update CS-Cart’s stock data fields. After delivery, I’ll provide installation steps and well-commented code for easy future maintenance. Based on similar CS-Cart integrations I’ve done, this can be completed within 3-5 days. I’m ready to start as soon as you’re set.
