Why

"Plenty of leads and opportunities and 1000s of accounts and contacts" with a 10+ team and 200–500 inquiries/month means deal ownership, account hierarchies, and referral attribution are now real problems — not hypothetical ones. Robotics sales cycles are long and consultative (months, multiple stakeholders per account), so a forgotten follow-up costs you a quarter, not a week. Referrals plus a web form is a clean two-channel setup, which is good news: you don't need omnichannel sprawl, you need one pipeline with clear ownership.

What you actually need

1. HubSpot Sales Hub Starter ($20/seat/mo) or Pipedrive Advanced ($34/seat/mo) — pick one this week. Both handle thousands of accounts/contacts, account-contact relationships, and a real opportunity pipeline. For 10+ users with referral tracking, HubSpot's free contact database plus Starter seats for closers tends to win on price.
2. A web form → CRM auto-route — your web form must create a lead record with owner assigned by round-robin or territory the second it's submitted. No human in the middle. HubSpot forms or Pipedrive's web form do this natively.
3. A habit — Monday pipeline standup — 30 minutes, every deal stuck >14 days in one stage gets moved forward, reassigned, or killed. With 10+ people this is the only thing that stops "I thought Raj was handling it."

Do this today

Sign up for HubSpot free at hubspot.com, then go to Settings → Properties → Deals and create one pipeline with five stages: Inbound → Qualified → Demo/Site Visit → Proposal → Closed-Won/Lost. Connect your web form (Marketing → Forms → Create) and set the form action to "Create contact + deal, assign owner round-robin across your 10 reps." By tomorrow every web inquiry lands as an owned deal instead of an email someone forgets to forward.

What to ignore

Skip Salesforce Sales Cloud Enterprise ($165/user/mo plus a $40k implementation partner) — at your stage it's a 9-month project that delays you solving the actual problem. Ignore ZoomInfo, Apollo, Outreach, and Salesloft pitches; with referrals + inbound as your channels, outbound tooling is solving someone else's problem. Don't let a HubSpot rep upsell you to Professional ($100/seat/mo) until Starter actually breaks.

What doing nothing costs you

A conservative 15% slippage on 350 inquiries/month (midpoint of your range) = ~52 lost opportunities/month. In industrial robotics, even a modest $40k average deal means roughly $25M/year of pipeline leaking — most of it referral leads, which are the most expensive to replace.

When to revisit this

When you need territory-based routing, multi-product pipelines, or your CFO wants forecast accuracy reports — then look at HubSpot Sales Hub Professional or Salesforce.
