HubSpot vs Salesforce vs a custom CRM: which one actually fits your SMB?

Every SMB owner we've worked with eventually asks the same question. HubSpot, Salesforce, or build my own? The right answer depends on three things: how custom your sales process actually is, how many seats you're paying for, and how often the CRM is the bottleneck instead of the spreadsheet around it.

Here's the honest version, written by people who don't run an affiliate program for any of them.

HubSpot

Best for: SMBs that need marketing automation more than they need pipeline depth. Companies under 50 seats where the salesperson and the marketer are the same person, or report to the same person.

• Strong free tier and a clean onboarding path. You can get value in week one.
• Marketing hub (email, forms, landing pages) is genuinely good. Sales hub is good enough for most SMBs.
• Pricing scales aggressively once you cross the free tier. Marketing Hub Professional starts around $890/month and most SMBs end up there.
• Customization has a ceiling. If your sales process has more than three meaningful branches, you'll hit it.

Salesforce

Best for: Sales-led SMBs with 25+ seats where pipeline complexity is the business, not a side effect. Multi-stakeholder deals, custom objects, deep reporting.

• Most flexible CRM on the market. You can model almost any sales motion.
• The implementation tax is real. Salesforce works the way your consultant configures it. Pick the consultant carefully.
• Pricing is per seat, per month, and it adds up. Sales Cloud Enterprise is $165 per user.
• If you're under 10 reps and your process fits in a spreadsheet, Salesforce is overkill.

Custom CRM

Best for: SMBs whose sales process IS the differentiator. Trades dispatching, multi-location services, two-sided marketplaces, anything where the workflow doesn't map cleanly onto a 'lead, opportunity, account' object model.

• Zero seat fees. You pay once for the build and host it cheaply on standard infrastructure (typically $20 to $200/month depending on scale).
• Owns the data model. Custom objects, custom workflows, integration points where you actually need them.
• Requires an engineering partner who understands ops, not just code. Most custom CRMs fail because they were built to a spec sheet instead of a workflow.
• Realistic build window for an SMB scope: 3 to 8 weeks. The investment makes sense when seat fees on HubSpot or Salesforce would eat the build cost inside a year or two.

How to decide

We use a three-question test with clients:

1. Does your sales process look like anyone else's in your industry? If yes, HubSpot or Salesforce, depending on size. If no, custom is on the table.
2. What's the cost of one bad lead handoff? If it's measured in hundreds, off-the-shelf is fine. If it's measured in tens of thousands (large project bids, multi-month deals, large catering orders), custom workflows pay for themselves fast.
3. Is the CRM going to grow with your team or fight it? If your ops lead is already maintaining a separate spreadsheet because the CRM doesn't fit, you've already paid for a custom build in time. You just haven't written the check.

If you'd like a one-hour second opinion on your specific stack, that's the conversation a free growth audit usually starts with. We don't sell HubSpot, we don't sell Salesforce, and we'll tell you to stay on the spreadsheet if that's the right answer.
