Google Workspace Add-on Portfolio

A portfolio of small, focused Google Workspace add-ons and Chrome extensions that automate repetitive tasks for business professionals — mail merge, scheduled reports, form notifications, file auditing, document generation. Each add-on solves one specific pain point inside tools people already use every day (Gmail, Sheets, Forms, Drive). The model is indie micro-SaaS: low build cost, recurring subscription revenue, organic discovery via Google Marketplace and Chrome Web Store. Reference: Amit Agarwal (labnol.org, Google Developer Expert) has built 8+ of these and turned it into a sustainable solo business.

Problem statement

Business professionals spend hours on tasks that should be automated — mail merge in Gmail, generating contracts from Google Sheets data, scheduling spreadsheet reports, auditing who has access to shared Drive files. Native Google Workspace doesn't solve these. Third-party SaaS is overkill and expensive. A focused add-on that does one thing well, inside the tool they already have open, is the right fit.

ICP (who exactly has this problem)

Operations managers and executive assistants who send bulk personalized emails
Finance and legal teams generating repetitive documents (invoices, contracts, agreements) from spreadsheet data
Marketing teams scheduling recurring reports out of Google Sheets
IT admins auditing Google Drive access at small-to-mid companies
Google Workspace power users who know the platform deeply but hit its limits constantly

Market and TAM

Google Workspace has 3 billion users. Even targeting the 1-5% of business power users = 30-150M addressable users. Google Marketplace has built-in distribution — users search for add-ons inside the product. Chrome Web Store is a second distribution channel. Market is proven: Mail Merge for Gmail (Mailmeteor, GMass, Yet Another Mail Merge) all have significant paid user bases. Document automation (Portant, Autocrat) has paying customers. This is a crowded but large market where niche execution wins.

Alternatives (how people solve this today)

Zapier / Make — works but requires knowing what to automate and costs more
Dedicated SaaS tools (Mailchimp for mail merge, DocuSign for docs) — expensive, over-engineered
Manual work — the default for most small teams
Other Workspace add-ons — exist but most are poorly maintained, bad UX, or compliance-questionable

GTM angle

Google Marketplace is the primary distribution — users actively search for solutions inside Workspace. SEO is secondary (long-tail "mail merge gmail" type searches still have volume). Build one add-on, get it to 1,000 paying users, use that install base as the audience for the next one. Each add-on cross-promotes the others. The portfolio compounds — Amit Agarwal's model exactly.

How it works

Pick one high-frequency pain point in Google Workspace (start with mail merge or document generation — proven demand)
Build a Google Apps Script add-on or Chrome extension solving exactly that problem
Publish to Google Marketplace + Chrome Web Store
Charge $5-15/mo per user or a flat annual license
Iterate based on reviews, add one new add-on every 2-3 months
Each new add-on installs cross-promote the others

Riskiest assumption

Google Marketplace discovery is enough to drive installs without a marketing budget. If organic Marketplace search doesn't convert, you need SEO or paid acquisition — both cost time/money that undercut the micro-SaaS model. Validate by checking install counts and review velocity on existing competitors in the Marketplace before building.
