Custom CRM vs Salesforce vs HubSpot — when a build beats a buy

Most CRM advice is sold to you by the CRM vendor's reseller. Here's the advice from someone who's actually built 30 of them.

Start with the question almost no one asks

Before I recommend any CRM — bought or built — I ask one question: what does the operator do 50 times a day inside this software? If the answer is a unique workflow that doesn't match Salesforce's pipeline model or HubSpot's deal stages, a packaged CRM is going to fight you forever.

The most expensive CRM implementations I've seen aren't the ones with the biggest license fees. They're the ones where the team configured a SaaS CRM to do something it wasn't designed for, then paid a consultancy ₹40L a year to keep the duct tape together.

Buy if all of these are true

Your sales process maps to a textbook B2B pipeline (lead → MQL → SQL → opp → close). Your team is more than 30 reps and growing fast. You need pre-built integrations to dozens of tools (Zoom, Slack, Outreach, Gong, etc.). You'd rather pay a license than hire engineering.

If those are true, HubSpot Pro or Salesforce Sales Cloud earns its money. Don't overthink it.

Build if any of these are true

Your workflow is non-standard — multi-store retail with billing + inventory + lookbook, or healthcare with multi-doctor scheduling + insurance claims, or solar with quote generation + state subsidy calculations.

You need to embed CRM logic inside your customer-facing product or operator app. Off-the-shelf CRMs make this hard because their data model is closed.

You serve customers in WhatsApp-first markets. None of the big CRMs do WABA-first natively. We build that on day one.

You're at SME scale (₹2–50 Cr revenue) and a license fee for 20 seats would buy you a full custom CRM with everything you actually need.

The numbers that decide it

HubSpot Pro: ~₹80,000/mo for 5 seats + onboarding consultant. Annual landed cost: ~₹15L.

Salesforce: ~₹3L/mo for 20 seats + admin + Apex developer. Annual landed cost: ~₹50L+.

Sphyx custom CRM: ₹2.5L–₹10L one-time build + ₹15–30K/mo managed hosting. Year 1: ~₹6L. Year 2+: ~₹3L. You own the source code.

After 3 years a custom build is usually 5–10× cheaper. The risk is that you need an engineering partner who'll still be around in 3 years.

The integration argument is overrated

Everyone tells you SaaS CRMs win on integrations. In practice, your team uses 4–6 of those 400 integrations. The rest are vapor. A custom CRM can integrate with all 6 in a week — and only those 6 are tested, supported, and won't break on a partner platform's API change.

The honest framing: SaaS CRM integrations are insurance against a future you're not sure you'll need. Custom CRM integrations are paved roads to the future you already have.

The take-home

If you can't answer 'what does my operator do 50 times a day' in one sentence, you're not ready to choose a CRM. Map that first. Then the right answer becomes obvious.
