Google Apps Script
Automate Google Workspace
with Apps Script
We write custom Google Apps Script solutions that automate Sheets, Gmail, Drive, Calendar, Docs, and Forms — and connect them to any external API including Twilio, ChatGPT, WhatsApp, QuickBooks, and Make.com — turning your entire Google Workspace into a powerful, event-driven automation engine.

Calendar3 Ways We Build with Apps Script
Every Apps Script project is built around the right trigger — whether that is a button inside a Sheet, a scheduled time job, a real-time cell edit, or an inbound HTTP webhook from an external platform.
Google Workspace Automation
Apps Script has native access to all Google Workspace services — Sheets, Gmail, Drive, Calendar, Docs, Forms, and Slides — without needing any external API calls. We write scripts that read from Sheets, create Drive folders, send Gmail campaigns, auto-fill Docs from data, create Calendar events from form submissions, and generate Slides reports — all from a single trigger inside Google's own ecosystem, eliminating the need for external automation platforms for straightforward Workspace workflows.
External API Integration
Apps Script's UrlFetchApp service makes HTTP GET and POST requests to any REST API — with custom headers, OAuth tokens, and JSON payloads. This means Apps Script can call Twilio to send SMS, OpenAI to generate ChatGPT content, WhatsApp Business API for messaging, Make.com webhooks to trigger multi-platform scenarios, and any other external service — making Google Workspace the central hub that talks to every tool in your business stack.
Script Triggers & Scheduling
Apps Script supports four trigger types that fire automatically — button triggers attached to spreadsheet UI elements, on-edit triggers that fire the moment any cell changes, form-submit triggers linked to Google Forms, and time-based triggers running hourly, daily, weekly, or on a custom cron schedule. We configure the right trigger combination for each use case, and Apps Script can also act as a webhook receiver via doGet and doPost functions — accepting incoming data from any external platform.

What We Build With Google Apps Script
Real Apps Script projects we have delivered — automating Google Workspace and connecting it to external platforms so teams accomplish more without leaving the tools they already use every day.
Sheets Button → Webhook → Make.com → QuickBooks Invoice
We built a Google Sheet where a finance team enters invoice line items across rows. A custom "Create Invoice" button — added via Apps Script — fires a webhook to Make.com with all the data as a structured JSON payload. Make.com creates the complete QuickBooks invoice immediately. Accountants work entirely in Sheets and generate QuickBooks invoices with one click — no duplicate data entry, no switching platforms.
Twilio SMS Drip Campaign — Scheduled from Sheets
We built a 10-message SMS drip sequence managed entirely from a Google Sheet. A contact is enrolled by adding their phone number and clicking Start. A daily Apps Script time trigger checks each contact's enrollment date, calculates which message is due — day 2, day 4, day 6 and so on — and calls the Twilio API to send it. Every send is logged back to the Sheet with timestamp and status. The entire multi-week campaign runs without anyone touching it after enrolment.
ChatGPT Content Generator Inside Google Sheets
We built an in-Sheets AI content tool where a user fills in topic, target audience, tone, and a Google Drive document link. An Apps Script button calls the OpenAI ChatGPT API with a prompt built from those cells and writes the generated content — business plan sections, social post copy, FAQ answers, product descriptions — directly back into adjacent cells. Teams generate AI content without leaving Sheets or knowing anything about prompt engineering.
WhatsApp Task Notifications on Cell Edit
We built a task board inside Google Sheets with an on-edit Apps Script trigger watching the "Assigned To" column. The moment a team member's name is entered, the script looks up their phone number from a reference tab and sends a WhatsApp Business API message with the task name, deadline, and priority — within seconds of the cell being edited. When the task is marked complete, a confirmation WhatsApp goes to the team lead automatically.
Google Sheets as a Project Management System
We built a full project management system inside Google Sheets using Apps Script — handling Gantt chart layout formatting when dates change, colour-coding task status indicators, creating new project template sections automatically, generating weekly reminder emails from Gmail for upcoming deadlines, and updating Google Calendar events when project milestone dates are adjusted. Project managers get a purpose-built PM tool with zero additional software licences.
Auto-Generate Google Docs Reports from Sheets Data
We build Apps Script pipelines that read structured data from a Google Sheet — client name, metrics, dates, performance figures — and automatically populate a Google Docs template with that data, replacing placeholder tags with the correct values. The finished Doc is saved to a specific Google Drive folder and emailed as a PDF attachment via Gmail to the relevant recipient — generating personalised reports, proposals, or contracts in seconds from a spreadsheet row.
Apps Script Connects With
From messaging APIs and AI platforms to accounting software and automation tools — Apps Script can reach any external service your business depends on.
