# ERP with Google Workspace and Google Appscripts with code samples.<\/h1>\n\n\n\n

Overview<\/h2>\n\n\n\n

An ERP (Enterprise Resource Planning) system built on Google Workspace can leverage the suite\u2019s core apps\u2014Sheets, Docs, Drive, Gmail, Calendar\u2014and automate workflows with Google Apps Script. Below are common ERP modules and sample Apps Script snippets that illustrate how to connect them.<\/p>\n\n\n\n

\n\n\n\n

1. Inventory Management (Sheets\u202f+\u202fDrive)<\/h2>\n\n\n\n

Key idea:<\/strong> Store inventory data in a Google Sheet; use Apps Script to update stock levels when a purchase order is approved.<\/p>\n\n\n\n

\/**\n * Decrease inventory when a PO is approved.\n * Triggered from a Google Form submission or a custom menu.\n *\/\nfunction processPurchaseOrder(e) {\n  const poSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('PurchaseOrders');\n  const invSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Inventory');\n\n  \/\/ Assume the form sends: PO_ID, ITEM_ID, QUANTITY\n  const poId = e.values[0];\n  const itemId = e.values[1];\n  const qty = Number(e.values[2]);\n\n  \/\/ Find the inventory row for the item\n  const invData = invSheet.getDataRange().getValues();\n  for (let i = 1; i < invData.length; i++) {\n    if (invData[i][0] === itemId) {               \/\/ Column A = Item ID\n      const currentStock = Number(invData[i][2]); \/\/ Column C = Stock Qty\n      invSheet.getRange(i + 1, 3).setValue(currentStock - qty);\n      break;\n    }\n  }\n\n  \/\/ Mark PO as processed\n  const poRow = e.range.getRow();\n  poSheet.getRange(poRow, 5).setValue('Processed'); \/\/ Column E = Status\n}<\/code><\/pre>\n\n\n\n
Deploy:<\/em> Attach processPurchaseOrder<\/code> to a Form submit<\/strong> trigger or a custom menu item in the PO sheet.<\/p>\n\n\n\n
\n\n\n\n
2. Sales Order Entry (Forms\u202f+\u202fSheets\u202f+\u202fGmail)<\/h2>\n\n\n\n
Key idea:<\/strong> Capture sales orders via Google Form, store them in a Sheet, and automatically email an order confirmation.<\/p>\n\n\n\n
function onSalesFormSubmit(e) {\n  const ss = SpreadsheetApp.getActiveSpreadsheet();\n  const orders = ss.getSheetByName('SalesOrders');\n  const row = e.range.getRow();\n\n  \/\/ Pull data from the form submission\n  const [orderId, clientEmail, product, qty] = e.values;\n\n  \/\/ Add a timestamp and status\n  orders.getRange(row, 6).setValue(new Date());      \/\/ Column F = Received\n  orders.getRange(row, 7).setValue('Pending');      \/\/ Column G = Status\n\n  \/\/ Build email body\n  const body = `\n    Hi,\n\n    Thank you for your order #${orderId}. Here are the details:\n\n    \u2022 Product: ${product}\n    \u2022 Quantity: ${qty}\n\n    We will notify you once the order is processed.\n\n    Best,\n    Sales Team\n  `;\n\n  \/\/ Send confirmation\n  GmailApp.sendEmail(clientEmail, `Order Confirmation #${orderId}`, body);\n}<\/code><\/pre>\n\n\n\n
Deploy:<\/em> Set a Form submit<\/strong> trigger for onSalesFormSubmit<\/code>.<\/p>\n\n\n\n
\n\n\n\n
3. Expense Reporting (Docs\u202f+\u202fSheets\u202f+\u202fDrive)<\/h2>\n\n\n\n
Key idea:<\/strong> Employees fill a Google Form; a script generates a formatted expense report in Docs and saves it to a shared Drive folder.<\/p>\n\n\n\n
function generateExpenseReport(e) {\n  const templateId = '1A2bC3dEfGhIjKlMnOpQrStUvWxYz'; \/\/ Docs template file ID\n  const folderId   = '0B1cD2eF3gHiJkLmNoPqRsTuVwXyZ'; \/\/ Shared Drive folder\n\n  const [empName, date, category, amount, description] = e.values;\n\n  \/\/ Make a copy of the template\n  const copy = DriveApp.getFileById(templateId).makeCopy(`${empName} \u2013 Expense ${date}`);\n  const doc  = DocumentApp.openById(copy.getId());\n\n  \/\/ Replace placeholders in the template\n  const body = doc.getBody();\n  body.replaceText('{{EMPLOYEE}}', empName);\n  body.replaceText('{{DATE}}', date);\n  body.replaceText('{{CATEGORY}}', category);\n  body.replaceText('{{AMOUNT}}', `$${Number(amount).toFixed(2)}`);\n  body.replaceText('{{DESCRIPTION}}', description);\n  doc.saveAndClose();\n\n  \/\/ Move to the shared folder\n  DriveApp.getFolderById(folderId).addFile(copy);\n  DriveApp.getRootFolder().removeFile(copy);\n}<\/code><\/pre>\n\n\n\n
Deploy:<\/em> Attach to the Form submit<\/strong> trigger of the expense form.<\/p>\n\n\n\n
\n\n\n\n
4. Project Management Dashboard (Sheets\u202f+\u202fCalendar)<\/h2>\n\n\n\n
Key idea:<\/strong> Sync project milestones from a Sheet to Google Calendar events.<\/p>\n\n\n\n
function syncMilestonesToCalendar() {\n  const ss = SpreadsheetApp.getActiveSpreadsheet();\n  const projSheet = ss.getSheetByName('Projects');\n  const cal = CalendarApp.getCalendarById('your-team@yourdomain.com');\n\n  const data = projSheet.getDataRange().getValues();\n  for (let i = 1; i < data.length; i++) {\n    const [projId, milestone, dueDate, status] = data[i];\n    if (status !== 'Scheduled') continue; \/\/ Only schedule once\n\n    \/\/ Create calendar event\n    cal.createAllDayEvent(`${projId} \u2013 ${milestone}`, new Date(dueDate));\n\n    \/\/ Mark as scheduled\n    projSheet.getRange(i + 1, 4).setValue('Scheduled');\n  }\n}<\/code><\/pre>\n\n\n\n
Deploy:<\/em> Run manually or set a time\u2011driven trigger<\/strong> (e.g., daily).<\/p>\n\n\n\n
\n\n\n\n
5. Approval Workflow (Gmail\u202f+\u202fSheets\u202f+\u202fApps Script)<\/h2>\n\n\n\n
Key idea:<\/strong> Send an approval request email with \u201cApprove\u201d \/ \u201cReject\u201d links that update a Sheet when clicked.<\/p>\n\n\n\n
function sendApprovalRequest(row) {\n  const ss = SpreadsheetApp.getActiveSpreadsheet();\n  const sheet = ss.getSheetByName('Approvals');\n  const [reqId, requester, amount, status] = sheet.getRange(row, 1, 1, 4).getValues()[0];\n\n  const approveUrl = ScriptApp.getService().getUrl() + `?action=approve&id=${reqId}`;\n  const rejectUrl  = ScriptApp.getService().getUrl() + `?action=reject&id=${reqId}`;\n\n  const html = `\n    <p>Approval needed for request #${reqId}:<\/p>\n    <ul>\n      <li>Requester: ${requester}<\/li>\n      <li>Amount: $${amount}<\/li>\n    <\/ul>\n    <p>\n      <a href=\"${approveUrl}\">Approve<\/a> |\n      <a href=\"${rejectUrl}\">Reject<\/a>\n    <\/p>\n  `;\n\n  GmailApp.sendEmail('manager@yourdomain.com',\n                     `Approval Request #${reqId}`,\n                     '',\n                     {htmlBody: html});\n}\n\n\/**\n * Web app entry point for approval links.\n *\/\nfunction doGet(e) {\n  const id = e.parameter.id;\n  const action = e.parameter.action;\n  const ss = SpreadsheetApp.getActiveSpreadsheet();\n  const sheet = ss.getSheetByName('Approvals');\n  const rows = sheet.getDataRange().getValues();\n\n  for (let i = 1; i < rows.length; i++) {\n    if (rows[i][0] == id) {\n      sheet.getRange(i + 1, 4).setValue(action === 'approve' ? 'Approved' : 'Rejected');\n      break;\n    }\n  }\n  return HtmlService.createHtmlOutput('Your response has been recorded.');\n}<\/code><\/pre>\n\n\n\n
Deploy:<\/em> Publish the script as a Web app<\/strong> (execute as \u201cMe\u201d, accessible to \u201cAnyone\u201d). Call sendApprovalRequest<\/code> from a button or trigger.<\/p>\n\n\n\n
\n\n\n\n
6. Consolidated Reporting (Data Studio \/ Looker Studio)<\/h2>\n\n\n\n
While Apps Script handles data capture, you can connect the Sheets directly to Looker Studio for visual dashboards. No code is required beyond sharing the Sheet with the reporting service.<\/p>\n\n\n\n
\n\n\n\n

These snippets give a functional skeleton; you can extend them with validation, error handling, and role\u2011based access as needed for a production\u2011grade ERP built entirely on Google Workspace.<\/p>\n","protected":false},"excerpt":{"rendered":"
