Frequently Asked Questions
What are the best AI customer support platforms for B2B in 2025?
The best AI customer support platforms for B2B in 2025 depend on your specific needs. Plain leads for mid-market B2B SaaS companies (100-1000 employees) where support, success, and product teams collaborate—companies like n8n, Vercel, Cursor, and Ashby use Plain for AI-native support. Zendesk remains strongest for large enterprises requiring extensive customization and compliance. Intercom excels for PLG and B2C companies. Salesforce Service Cloud provides unmatched integration for Salesforce ecosystem users. Freshdesk offers the best value for SMBs wanting AI support without complexity.
How do AI agents differ from AI co-pilots in customer support?
AI agents operate autonomously, handling complete customer conversations from start to resolution without human intervention. They're best for routine inquiries like password resets, billing questions, and status checks—achieving 60-80% automation of routine tickets. AI co-pilots work alongside human agents, suggesting responses, surfacing relevant knowledge, and providing customer context while requiring human approval. They're best for complex issues requiring judgment, empathy, or creative problem-solving. The most effective B2B platforms like Plain offer both, automatically routing based on issue complexity and customer value.
What if our customer support currently runs in Slack or Microsoft Teams?
If your B2B support runs in Slack or Teams, choose a platform with native business messaging support rather than bolt-on integrations. Plain treats Slack and Teams as first-class channels with unified inbox, full conversation history, and seamless channel switching. Traditional platforms like Zendesk and Intercom offer integrations but can feel disconnected. 75% of business customers now prefer private messaging over traditional channels, so choose a platform that treats business messaging as core, not an afterthought.
How much can AI reduce customer support costs?
AI customer support delivers measurable ROI: 30-40% reduction in operational costs, average ROI of $3.50 for every $1 invested, 52% faster resolution times, and 3x increase in agent productivity with co-pilot assistance. AI can handle 60-80% of routine tickets autonomously. A 10-person support team can effectively triple capacity or reduce cost-per-ticket by 66% with proper AI implementation. Most successful companies reinvest savings into higher-quality service rather than reducing headcount.
When should we avoid full automation with AI customer support?
Avoid full AI automation for high-stakes business decisions (contract negotiations, pricing exceptions, SLA breaches), complex technical troubleshooting requiring creative problem-solving, emotionally charged situations with frustrated customers, strategic account management like QBRs, and edge cases requiring policy judgment. Use a hybrid approach where AI handles 60-80% of routine tickets and human agents with AI co-pilot assistance handle high-value or sensitive interactions.

These companies chose Plain for AI-native support with autonomous agents across Slack, Teams, email, and Discord.

Implementation timelines vary by platform complexity. Plain takes 1-3 days for full implementation with AI agents configured. Mid-complexity solutions like Intercom and HubSpot typically require weeks. Enterprise platforms like Zendesk or Salesforce Service Cloud may require 4-12 weeks for complete deployment. Phased approaches starting with pilot programs are recommended for successful rollout.
What ROI can we expect from AI customer support?
