 */

function doGet() {
  const ss = SpreadsheetApp.getActiveSpreadsheet();
  const sheet = ss.getSheetByName("Inventory");
  const data = sheet.getDataRange().getValues();
  const headers = data.shift();
  
  const json = data.map(row => {
    let obj = {};
    headers.forEach((h, i) => obj[h.toLowerCase().replace(" ", "")] = row[i]);
    return obj;
  });
  
  return ContentService.createTextOutput(JSON.stringify(json))
    .setMimeType(ContentService.MimeType.JSON);
}

function doPost(e) {
  const ss = SpreadsheetApp.getActiveSpreadsheet();
  const sheet = ss.getSheetByName("Inventory");
  const item = JSON.parse(e.postData.contents);
  
  const data = sheet.getDataRange().getValues();
  let found = false;
  
  for(let i = 1; i < data.length; i++) {
    if(data[i][0] == item.sku) {
      sheet.getRange(i + 1, 1, 1, 5).setValues([[item.sku, item.name, item.category, item.stock, item.minlevel]]);
      found = true;

Inventory Management Masterclass 2026

The Blueprint for Modern Inventory Optimization & Supply Chain Efficiency

In the digital commerce era, inventory is no longer just "stuff in a warehouse"—it is **liquid capital**. Poor inventory management is the single most common cause of small business failure, leading to the twin perils of "Stock-outs" (losing sales) and "Overstocking" (trapping cash flow in depreciating assets).

1. The Psychology of the SKU

Every Product Identifier (SKU) tells a story about your business demand. High-performing companies utilize **ABC Analysis** to categorize their inventory:

  • Category A: High-value items with low frequency (20% of items, 70% of value). These require tight control and precise tracking.
  • Category B: Mid-range items with moderate turnover.
  • Category C: Low-value items with high frequency. These can be managed with looser controls to save administrative time.

2. Solving the "Dead Stock" Problem

Dead stock refers to inventory that hasn't moved in 90 to 180 days. This inventory is a liability; it takes up physical space, incurs insurance costs, and risks obsolescence. Our **StockFlow Cloud** tool allows you to monitor stock levels in real-time to identify these slow-movers before they become a financial burden. Strategic liquidation (discounts or bundles) is often better than holding stagnant inventory for "full price."

"Inventory is money sitting around in another form. Every day an item sits on your shelf, it loses value through opportunity cost."

3. Real-Time Sync vs. Batch Processing

Legacy systems often rely on "Batch Processing," where inventory levels are updated once a day. In the age of multi-channel selling (Amazon + Shopify + Physical Store), this is a recipe for disaster. Using a **Cloud-Synced SPA** (Single Page Application) built on Google’s infrastructure ensures that whether you are at your desk or on your mobile device, the "source of truth" is always accurate.

4. Safety Stock and Reorder Points

The "Reorder Point" is the magic number that triggers a new purchase order. It is calculated as:
(Average Daily Sales × Lead Time) + Safety Stock. By setting a MinLevel in our tool, you create an automated early-warning system that prevents the catastrophic loss of sales due to inventory exhaustion.

5. Technical Benefits of a Blogger-GAS Architecture

Why build an inventory tool on Blogger and Google Apps Script?

  1. Zero Hosting Cost: You get a professional database (Google Sheets) and a high-speed frontend (Blogger) with no monthly fees.
  2. Customization: Unlike rigid SaaS platforms, you can edit the HTML/JS to add barcode scanning, image support, or custom reporting.
  3. Security: Data is stored in your own Google Drive, giving you full ownership and control over your business metrics.

Frequently Asked Questions

Is this tool secure for my business data?

Yes. The tool connects your specific Blogger page to your specific Google Sheet via a unique API URL. As long as you don't share your Web App URL, your data remains private within your Google account.

Can I use this on multiple devices?

Absolutely. Since this is an SPA (Single Page Application), the Blogger page will work on smartphones, tablets, and desktops, allowing your team to update stock from the warehouse floor.
