If you're running operations, finance, or IT at a 100-person Indian company, you've probably had this conversation at least once: "Should we just move everyone to Zoho? Or stick with Google? Our Enterprise clients all use Teams, so maybe Microsoft?" The question sounds simple. The answer isn't.
At 100 seats, a ₹200-per-user-per-month pricing gap compounds to ₹2.4 lakh per year. That's before GST treatment, migration effort, or the adjacent tools you'll still need to buy. The suite you pick today will also shape your CRM, HR software, and finance tool choices for the next 3 to 5 years, because every vendor wants you inside their ecosystem.
This guide cuts through the vendor positioning and gives you a direct comparison across real INR costs, GST compliance, feature depth, and migration realism, so you can make a considered decision rather than defaulting to whatever the loudest voice in the room recommends.
Why This Decision Is Harder Than It Looks at the 100-Person Mark
Small companies can afford to experiment. A 10-person team switching from Google to Microsoft loses a long weekend. A 100-person company switching loses weeks of IT effort, training budget, and productivity. The stakes are genuinely different.
SaaS finance integrations India comparison articles gloss over entirely. Foreign SaaS billed directly from Microsoft or Google attracts 18% GST under the reverse charge mechanism (RCM), which the Indian company must self-assess and deposit. Many finance teams discover this only during an audit. Zoho, billed through Zoho India Pvt Ltd, issues clean GST invoices from day one.
INR volatility adds another layer. Microsoft 365 and Google Workspace are USD-denominated. When the rupee weakens, your renewal cost rises in INR terms without any change in your usage. A tool budgeted at ₹900 per user per month in January can cost ₹960 in October on the same USD plan. At 100 seats, that drift is material.
Zoho CRM vs HubSpot India adjacent categories. Zoho One includes CRM, HRMS, and accounting. Microsoft brings you closer to Azure and Power Platform. Google assumes you'll integrate third-party tools for everything beyond collaboration. Understand the ecosystem pull before you sign the order.
Key takeaway: At 100 seats, per-seat pricing is just the starting number. GST treatment, INR exposure, and ecosystem lock-in often move the real cost more than the sticker price difference.
The Contenders: What Each Suite Actually Covers
It's worth being precise about what you're actually getting, because the marketing summaries are misleading in different directions for each vendor.
best HR software India. At a single per-user price, you get 45+ applications: Zoho CRM, Zoho Books (accounting), Zoho People (HRMS), Zoho Projects, Zoho Desk (customer support), Zoho Mail, Zoho Cliq (messaging), Zoho Meeting, and more. For a 100-person company that currently pays separately for CRM, HR software, and a helpdesk, this consolidation argument is real.
Microsoft 365 vs Google Workspacektop apps (Word, Excel, PowerPoint, Outlook), Teams, Exchange, SharePoint, OneDrive, and access to the Power Platform at the lower tiers. What it doesn't include at Business Standard pricing: Intune for device management, Defender for Endpoint, or Dynamics 365. Those are separate, expensive products. Don't let a Microsoft sales deck blur those lines.
Google Workspace Business Starter and Standard cover Gmail, Calendar, Drive, Docs, Sheets, Slides, Meet, and Chat. Collaboration is the core value proposition. AppSheet (no-code apps) is included at Business Standard. But there's no native CRM, no HR module, no accounting tool. Google's bet is that you'll integrate the best-of-breed tools you already love.
Watch out: Vendors demo their full product catalog. Before you sit through a Zoho or Microsoft demonstration, write down the 5 specific jobs your team needs the suite to do. Make them show you exactly those workflows, not the shiny features you don't need.

Real INR Pricing: What 100 Seats Actually Costs in 2025
Here's what the numbers look like at 100 seats on annual billing, using current 2025 pricing.
Zoho One: approximately ₹1,994 per user per month on the annual plan, billed in INR directly through Zoho India. At 100 seats, that's ₹23.93 lakh per year before any negotiated discount. GST invoice comes clean from Zoho India, input tax credit claimable normally.
Microsoft 365 Business Standard: USD 12.50 per user per month, billed in USD. At a conservative ₹84 exchange rate, that's roughly ₹1,050 per user per month before GST. Add 18% GST under RCM if purchased direct, and the effective cost becomes approximately ₹1,239 per user per month. At 100 seats, ₹14.87 lakh per year. Through an Indian reseller like Easexpense, you pay a similar or slightly lower figure with a clean GST invoice instead of self-assessed RCM.
Google Workspace Business Starter: USD 6 per user per month, or about ₹504 per user pre-GST. With RCM, approximately ₹595. At 100 seats, roughly ₹7.14 lakh per year. Business Standard at USD 12 doubles that to around ₹14.28 lakh with GST.
The gap between Zoho One and Microsoft 365 Business Standard at 100 seats is roughly ₹9 lakh per year — but Zoho's price includes CRM and HRMS that Microsoft would charge you separately for.
That's the critical context. Microsoft 365 at ₹14.87 lakh per year looks cheaper than Zoho One at ₹23.93 lakh until you add Dynamics 365 for CRM (starts at USD 65 per user per month), a separate HRMS, and a helpdesk tool. The comparison becomes much closer, or even inverts, when you account for what Zoho One bundles in.
GST, Invoicing, and Compliance: The India-Specific Reality
This section exists because most comparison guides are written by people who don't file Indian GST returns. Let's fix that.
When an Indian company buys Microsoft 365 or Google Workspace directly from the vendor's website, the transaction is treated as an import of services. Under Section 5(3) of the IGST Act, the recipient (your company) is required to self-assess and deposit 18% GST under the reverse charge mechanism. The foreign vendor doesn't collect it for you. Many companies, especially those without a dedicated finance team, simply don't do this.
The downstream risk is material. During a GST audit, the department can disallow input tax credit on these purchases and levy interest at 18% per annum on the unpaid tax from the date it was due. At ₹14.87 lakh of annual software spend and 18% GST, you're looking at approximately ₹2.68 lakh per year in GST liability that may have been unrecorded.
Purchasing Microsoft 365 or Google Workspace through an authorized Indian reseller changes the mechanics entirely. The reseller collects GST, issues a proper tax invoice with their GSTIN, and you claim input tax credit through the normal forward charge mechanism. No self-assessment, no RCM deposit, no audit risk.
Zoho One, billed through Zoho India Pvt Ltd, is a domestic transaction. Clean GST invoice from day one. This is a meaningful operational advantage for companies without a dedicated CFO or tax consultant running the books.
Action: Check your Microsoft or Google billing portal right now. If your invoice is from a US entity with no GSTIN, your company may have an unrecorded RCM liability. Switching billing to an authorized Indian reseller corrects this going forward.
There's a secondary benefit worth naming. Zoho Books, included in Zoho One, is your accounting software. When your productivity suite and your accounting tool share a vendor and a single GST invoice, your monthly book closure is measurably simpler. That integration isn't theoretical — it's one less reconciliation task for your finance team every month.
Feature-by-Feature Breakdown: Where Each Suite Wins
Honest category-by-category assessment, without the vendor positioning.
Email and calendar
Microsoft Exchange and Outlook remain the enterprise standard. Compliance archiving, e-discovery, shared mailboxes, and rules-based routing are mature and well-documented. Gmail wins on search speed and mobile UX, and most people who've used both prefer it for day-to-day email. Zoho Mail is functional and reliable, but it's third in this category by honest measure. If email is your team's primary communication medium, this matters.
Real-time collaboration and documents
Google Workspace leads here and isn't close. Real-time co-editing, comments, version history, and sharing are the product's founding purpose. Microsoft has substantially closed the gap with Microsoft 365 co-authoring, but the experience on complex documents still occasionally degrades. Zoho Writer handles everyday documents well; the friction appears with complex formatting or when a client sends a macro-heavy Excel file that doesn't translate cleanly.
CRM and business applications
This is where Zoho One's value proposition is sharpest. Zoho CRM, Zoho Books, Zoho People, and Zoho Desk are all included in the Zoho One price. Microsoft's equivalent, Dynamics 365, starts at USD 65 per user per month as a separate license. Google relies entirely on third-party integrations: HubSpot, Salesforce, QuickBooks. For a 100-person company looking to consolidate vendors, Zoho One's breadth here is a genuine cost advantage.
Security and device management
Microsoft Intune and Defender are the best options for Windows-managed device fleets. If your IT setup involves 100 Windows laptops that need MDM, antivirus, and compliance policy enforcement, Microsoft 365 Business Premium (one tier up from Business Standard) is difficult to beat. Google's BeyondCorp is well-regarded in zero-trust security circles but is more complex to configure. Zoho OneAuth covers MFA and basic SSO adequately for most SMBs.
For detailed pricing across all three vendors on the Easexpense marketplace, you can compare current India plans at the Easexpense marketplace or see a structured breakdown at our SaaS comparisons page.
After seeing the feature breakdown across these five dimensions, most 100-person Indian companies find they have a clear lean — and it usually comes down to whether they need deep Windows device management or whether a consolidated business OS is the priority.
Key takeaway: No single suite wins every category. Microsoft leads on email enterprise features and Windows device management. Google leads on real-time collaboration. Zoho One leads on per-rupee business application breadth.

We can pull utilization data from your existing Google Workspace or Microsoft 365 account and show you real adoption numbers before you commit to a migration.
Migration Reality: What Moving 100 People Actually Takes
Every vendor minimizes migration friction during the sales process. Here's the honest version.
A Google-to-Microsoft migration for 100 users takes 2 to 4 weeks of active IT effort: pre-migration cleanup, cutover weekend, post-migration support. Email migration is the bulk of the work. Google Drive to SharePoint/OneDrive file migration adds another 1 to 2 weeks depending on folder structure and data volume. Training staff who've spent years in Gmail to reach productivity parity in Outlook typically takes 4 to 6 weeks of adjusted workflows.
Moving to Zoho One from either platform has more touchpoints. It's not just email migration — it's also data migration into Zoho CRM (if you're replacing Salesforce or HubSpot), Zoho Books (if you're replacing QuickBooks or Tally's cloud version), and Zoho Projects. Each functional migration is a separate project with its own data mapping, cleanup, and user training requirement.
A 90-person logistics company based in Pune that we helped migrate from G Suite to Zoho One took 11 weeks end-to-end. Email migration went smoothly in week 2. The Zoho CRM data migration took 4 additional weeks because their Salesforce export had years of inconsistent lead source tagging that needed cleaning. Zoho Books setup took another 3 weeks because their Tally data required a chartered accountant to validate the opening balances. The CEO had budgeted 4 weeks. The reality was closer to 3 months of elevated IT overhead.
That's not an argument against migrating. It's an argument for planning the migration budget honestly before you sign the order form.
Which Suite Fits Which Kind of Indian Company
Choose Zoho One if: you want to consolidate CRM, HR, accounting, and productivity under a single INR invoice, you're not deeply dependent on Microsoft's Windows device management, and your team is willing to accept that some tools (Zoho Writer, Zoho Cliq) are functional rather than best-in-class. The unit economics at 100 seats are compelling when you factor in the apps included.
Choose Microsoft 365 if: your team runs Windows at scale, you use or plan to use Power BI, Azure, or Power Automate, or your enterprise clients require Teams and SharePoint interoperability. Microsoft's ecosystem depth for Windows-native companies is genuinely hard to replicate.
Choose Google Workspace if: your team is remote-first, collaboration velocity is the primary concern, and you're comfortable managing a best-of-breed stack for CRM and finance through integrations. Google Workspace Business Starter at roughly ₹7.14 lakh per year for 100 seats is the lowest-cost entry point if core productivity is all you need from the suite.
Hybrid setups are common and often pragmatic. A company running Google Workspace for email and collaboration plus Zoho CRM and Zoho Books for business functions is a reasonable configuration — but it introduces license management complexity. You're now tracking renewals, GST invoices, and user counts across 2 to 3 separate vendor relationships. That's manageable with the right tooling.
Action: Before committing to any suite migration, connect your existing accounts to Easexpense Spend Analytics. See which features your team actually uses, which licenses are sitting idle, and what shadow SaaS they've signed up for independently. Real usage data should drive this decision, not vendor demos.
Total Cost of Ownership Over 3 Years: A Side-by-Side Model
Three-year TCO is the honest frame for this decision. Here's a simplified model at 100 seats, annual billing, growing to 120 seats by year 3.
Zoho One TCO over 3 years: licensing approximately ₹75 to 85 lakh (including seat growth), near-zero adjacent tool spend (CRM, HR, helpdesk included), migration cost approximately ₹3 to 5 lakh (IT contractor + training), GST invoicing from India throughout. Total estimated TCO: ₹78 to 90 lakh.
Microsoft 365 Business Standard TCO over 3 years: licensing approximately ₹45 to 55 lakh (including seat growth and INR fluctuation buffer), plus separate CRM (HubSpot or Dynamics: ₹20 to 40 lakh depending on tier), HRMS (₹5 to 10 lakh), migration and training approximately ₹3 to 4 lakh. Total estimated TCO: ₹73 to 109 lakh depending on the CRM choice.
Google Workspace Business Standard TCO over 3 years: licensing approximately ₹43 to 50 lakh, plus similar adjacent tool spend as Microsoft, migration lower if staying within Google. Total estimated TCO: ₹68 to 100 lakh.
The ranges are wide because the adjacent tool choices drive most of the variance. Zoho One's TCO advantage is real but narrower than the per-seat sticker comparison suggests, especially if your team needs Microsoft Teams for external client meetings (a very common requirement) or retains an Adobe Creative Cloud subscription for design work.
Key takeaway: Zoho One's TCO advantage is strongest when you can genuinely retire your CRM, HRMS, and helpdesk tools. If your team still needs even one major Microsoft or Google-adjacent tool, the gap narrows significantly.
How to Run This Decision Without a Full-Time IT Head
Most 100-person Indian companies don't have a dedicated IT lead. This decision often lands on the COO, a senior finance person, or a founder who'd rather be doing almost anything else. Here's a practical process.
Start with what you actually use today. Pull your SaaS invoices for the last 6 months, check active login data in your current admin console, and identify the shadow SaaS your teams have signed up for independently on their company cards. You may find you're already paying for CRM through one tool, project management through another, and HR through a third — which changes the Zoho One consolidation math considerably.
Score each suite against your top 5 functional requirements, written before you speak to any vendor. Common requirements for 100-person Indian companies: email and calendar reliability, real-time document collaboration, CRM for sales, GST-compliant invoicing, and basic device security. Let your requirements set the evaluation criteria, not the vendor demo.
Run a 30-day pilot with a 10-person team before committing 100 seats. Pick a team that spans different job functions, not just tech-comfortable early adopters. Their friction points will surface the real adoption challenges.
Use Easexpense AI CIO to track renewal dates, consolidate invoices, and monitor utilization across your stack once you've made the decision. Whichever suite you pick, you'll want visibility into actual vs. licensed seat counts before each renewal.
And if you'd rather talk through your specific stack with someone who's seen 80+ Indian companies go through this decision, the most efficient path is a 15-minute call. No sales pitch, just a clear-eyed view of your options based on your actual situation.
Frequently asked questions
Is Zoho One cheaper than Microsoft 365 for a 100-person company in India?
At list price, Zoho One at roughly ₹1,994 per user per month is often more expensive than Microsoft 365 Business Standard on a pure per-seat basis. However, Zoho One includes CRM, HRMS, accounting, and helpdesk tools that Microsoft 365 does not. When you factor in the cost of those adjacent tools separately, plus 18% GST under RCM on Microsoft's direct billing, the total spend frequently equalizes or favors Zoho One. The real comparison is total cost of ownership across all the business applications you need, not the per-seat sticker price in isolation.
Do Indian companies pay GST on Microsoft 365 and Google Workspace?
Yes. When purchased directly from Microsoft or Google, the subscription is treated as an import of services and attracts 18% GST under the reverse charge mechanism, which the Indian company must self-assess and deposit with the government. The foreign vendor does not collect or remit this GST on your behalf. Purchasing through an authorized Indian reseller shifts that obligation to the reseller, who issues a standard GST invoice and allows the company to claim input tax credit through the normal forward charge mechanism. Many growing companies discover unrecorded RCM liabilities only during a GST audit, which can result in interest at 18% per annum on the unpaid tax amount. Switching to reseller billing resolves this cleanly going forward.
Can a 100-person Indian company replace Microsoft Office with Zoho One completely?
Many companies can, but the honest answer depends on your external collaboration requirements. Zoho Writer, Sheet, and Show handle everyday internal documents without meaningful friction. The challenges appear when clients or partners send complex Excel files with macros, require PowerPoint animations for external presentations, or — very commonly — invite your team to external Microsoft Teams meetings. Companies with significant enterprise client relationships typically keep at least a Microsoft 365 Basic plan for a subset of users to handle these interoperability scenarios. It's a hybrid model rather than a full replacement, which adds some license management overhead but keeps costs lower than full Microsoft 365 for the whole company.
How long does migration from Google Workspace to Microsoft 365 take for 100 users?
A straightforward email and calendar migration for 100 users typically takes 2 to 4 weeks of active IT effort, including pre-migration cleanup, the cutover weekend, and post-migration support for edge cases. File migration from Google Drive to SharePoint or OneDrive adds another 1 to 2 weeks depending on data volume, folder structure complexity, and how much cleanup the existing Drive structure needs. Training users to genuine productivity parity in the new environment typically takes an additional 4 to 6 weeks of adjusted workflows and support. Budget the IT contractor cost or internal IT-lead time realistically before you sign the migration order — most companies underestimate this phase significantly.
What is the best productivity suite for a fast-growing Indian startup with 80-150 employees?
For product or SaaS startups that are remote-first and collaboration-heavy, Google Workspace remains a strong default for its real-time co-editing experience and lower per-seat cost at the Starter tier. For service businesses, consulting firms, or companies that need CRM and invoicing bundled into their primary suite, Zoho One frequently delivers better unit economics once adjacent tool costs are factored in. Microsoft 365 makes the most sense for companies with enterprise clients requiring Teams integration, Windows-managed device fleets at scale, or existing Azure investment. There's no single correct answer — the best fit depends on your external collaboration requirements and which adjacent tools you'd otherwise buy separately.
Does Zoho One include a CRM, or is that a separate purchase?
Zoho CRM is fully included in the Zoho One subscription at no additional per-app charge. The Zoho One license covers 45+ Zoho applications, including Zoho CRM, Zoho Books (accounting and GST invoicing), Zoho People (HRMS), Zoho Projects (project management), and Zoho Desk (customer support). This bundling is one of Zoho One's primary cost advantages over Microsoft 365 or Google Workspace, where CRM and accounting tools require entirely separate vendor relationships and budgets. For a 100-person company currently paying for Salesforce or HubSpot, QuickBooks, and a separate HRMS, the consolidated Zoho One pricing often represents a meaningful annual saving even at its higher per-seat sticker price.
How can I find out which productivity suite my team is actually using before switching?
Connect your Google Workspace or Microsoft 365 account to a spend analytics tool that surfaces per-user login activity and license utilization data. Easexpense Spend Analytics does exactly this and also flags shadow SaaS that employees have signed up for independently using company cards or personal cards expensed back. Seeing real usage data before a migration decision prevents investing in a full suite swap when your team was only using 3 of the 10 features that justified the switch. It also helps identify whether you're paying for licenses that haven't been accessed in 60 or 90 days — a common source of recoverable SaaS spend at the 100-seat scale.
