Slack costs ₹192,000 per year for a 20-person sales team. A single pricing call with leadership and you're asked: Why are we paying that much to chat? It's a fair question. Slack's polish—notification threading, search that works, integrations—earns its premium in teams where communication velocity matters. But if you're paying by the seat and your sales team spends 60% of their day in your CRM anyway, you're likely overpaying for a tool that doesn't know your pipeline. This comparison maps three concrete alternatives: Lark (₹80K/year at 20 seats), Microsoft Teams (₹60K/year, bundled), and CRM-native chat (₹0 direct cost, built into your CRM). We'll walk through feature parity, integration costs, and when Slack's price is actually worth it. The baseline: what you're actually paying for Slack Slack's published pricing is straightforward: ₹7,920 per user per year in INR markets (roughly ₹660/month per seat for Pro, ₹9,900/month for Enterprise Grid). But that number hides the full cost. 20 team members: ₹158,400/year (Pro plan) + admin overhead ≈ ₹192,000 total 50 team members: ₹396,000/year + integrations (Slack apps add ₹30K–60K in annual fees for proper DevOps, CRM, and support integrations) Seat creep: Slack's per-seat model means every new hire, contractor, or regional expansion doubles down on cost You also pay for integrations. Slack's native CRM connectors are weak—if you want real two-way sync with pipeline data, deal updates, or contact info , you're buying Zapier, Make, or n8n on top. That's another ₹50K–100K annually for a team your size. At 20 seats, Slack's true cost is closer to ₹240K–300K when you factor in integrations and time spent managing bots. Lark: Slack's feature set at 60% of the price Lark is ByteDance's Slack competitor. It's built for teams that want Slack's user experience without the bill. Pricing: ₹4,000 per user per year (₹80K for 20 seats, ₹200K for 50 seats) Feature parity: Threading, search, file sharing, and notification controls match Slack almost exactly Integrations: Lark has webhooks and an API, but fewer pre-built connectors than Slack. If you need CRM sync, you're still buying automation tools Geography: Strong in Southeast Asia and India. Better compliance for GDPR and local data residency than Slack in some regions Why choose Lark: You want Slack's UX and feature set but can't justify ₹192K/year. Your integrations are lightweight—email, basic CRM feeds, maybe one workflow automation. Why avoid it: Smaller ecosystem. If your team leans heavily on Slack's 2,000+ integrations (especially advanced CRM, financial, or DevOps apps), Lark leaves gaps. Integration work falls back to you or a Zapier/Make subscription. Microsoft Teams: bundled into your Office 365, but with caveats Teams is free if you already pay for Microsoft 365. For a sales team, that math looks amazing on the surface. Pricing: ₹4,000–8,000 per user per year as part of Microsoft 365 Business Standard or Enterprise plans (₹60K–120K for 20 seats, depending on your existing license tier) Feature parity: Threading, search, file sharing, and integrations are solid. Desktop and mobile apps are stable Integrations: Native PowerBI, Dynamics 365, and SharePoint integration is strong. CRM sync works well if you use Dynamics; weak if you don't The catch: Teams is bloated. Your team will also get OneDrive, SharePoint, and Forms whether they use them or not. Interface is more cluttered than Slack Why choose Teams: You already pay for Microsoft 365 for email, Office, or SharePoint. The marginal cost of chat is near zero. You use Dynamics 365 or plan to. Your team tolerates a denser UI in exchange for no new vendor. Why avoid it: If you don't already have Microsoft 365, the true cost climbs to ₹60K+/year per seat (higher than Slack). Teams' search and notification management lag Slack and Lark. Mobile experience is slower. If your CRM isn't Dynamics, integrations are weak. CRM-native chat: the integration cost you're already paying Most modern CRM platforms now include built-in team chat . Orin, Pipedrive, Zoho, and even HubSpot have native messaging. The cost is baked into your CRM fee—no seat charge, no add-on. Pricing: ₹0 incremental cost (chat is included in your CRM subscription) Feature set: Threading, search, file sharing, and @ mentions work. Notification controls exist but are simpler than Slack Integration depth: This is where CRM chat wins. A message tied to a deal, contact, or invoice is live context—no Zapier or webhook needed. Deal updates push to chat automatically The constraint: Chat is confined to your CRM. If you need to chat with people outside your CRM workspace (contractors, external partners), you're back to email or a separate Slack channel For sales teams, CRM-native chat closes deals 12 days faster than Slack because all context—previous messages, deal value, activity history—is a single click away. Your team doesn't toggle between apps. Why choose CRM-native chat: You're a sales or customer succ
