HelloGrowthCRM — best for small teams selling on WhatsApp and phone
HelloGrowthCRM's free plan is built around the follow-up loop rather than a contact database: pipeline, reminders, WhatsApp inbox on a business number, and a built-in dialer, so a two-person team can run its genuine sales motion without paying. When you outgrow free, the paid plan is one all-inclusive price — ₹899/user/month in India, $10/user/month billed annually elsewhere — covering sequences, AI scoring, and GST invoicing with no add-on maze. The honest caveat: if your growth engine is content marketing and email nurture at scale, a marketing-suite CRM will fit that motion better than a sales-first product like this one.
HubSpot — best free tier for inbound and email-led teams
HubSpot's free CRM is the most famous on this list for good reason: a polished contact database, deal tracking, forms, and email tooling that a small inbound team can genuinely use. Watch out for the model: HubSpot's free tier is the doorway to a large paid suite, and the features that change outcomes — automation, scoring, serious calling — live in hubs where costs climb steeply as contacts grow. WhatsApp is an integration rather than a native inbox, which matters for phone-and-chat sales motions.
Zoho CRM — best free option for teams that will grow into the Zoho suite
Zoho offers free entry points into a famously broad ecosystem, and for a small team planning to run books, support, and campaigns on Zoho later, starting here compounds nicely. Watch out for the free tier's modest limits and the configuration appetite: Zoho rewards teams with an admin mindset and punishes those who wanted something working by Friday. WhatsApp and calling arrive through integrations, so budget setup time for a conversation-led motion.
Freshsales — best free-tier interface with a path to built-in phone
Freshsales offers a free tier with a clean, modern interface that small teams tend to like immediately, and the paid path adds a built-in phone channel and Freddy AI features. Watch out for where the gates sit: the capabilities a growing team reaches for — scoring, advanced automation, deeper reporting — are distributed across higher plans, and WhatsApp runs through integrations. A good choice if you value polish and may want the wider Freshworks platform later.
Bitrix24 — best free plan by sheer breadth of tools
Bitrix24's free plan is the most generous on this list in scope: CRM plus tasks, docs, chat, and even website building, which suits a bootstrapped team that wants one login for everything. Watch out for the cost of that breadth — the interface is dense, mobile use can feel heavy, and shaping it into a clean sales workflow takes patience and usually an admin. Teams that thrive on Bitrix24 tend to be operations-minded; teams that just want leads called tomorrow can find it a lot to hold.
EngageBay — best free all-in-one for marketing plus sales on a budget
EngageBay packages marketing, sales, and support tooling into one product with a free tier, positioning itself as an affordable alternative to the big suites, and small agencies in particular find the bundle appealing. Watch out for depth versus breadth: covering three departments in one budget product means each module is lighter than a specialist tool, and you should verify the specific automations, calling, and WhatsApp workflows you need rather than assuming the category label covers them.
