Custom CRM vs Salesforce or HubSpot: Build or Buy?

You have the Salesforce and HubSpot pricing pages open in two tabs, and someone in a meeting has asked why you don’t just build a CRM of your own. Custom CRM vs Salesforce or HubSpot comes down to how your business makes money, how many people will use the system and how much control you need over the data.

Custom CRM vs Salesforce and HubSpot: what’s the real difference?

Short answer: Salesforce and HubSpot are customer relationship management (CRM) products you rent per user, configure within the limits of your edition and get updates for automatically. A custom CRM is built for your workflow alone: you pay to build and run it, and in return there are no seat fees and no product limits, only your budget and your developer’s time.

Quick verdict:

• Choose Salesforce or HubSpot if your work is leads, deals and follow-ups, you have fewer than about 30 users, or nobody on your side would own a custom system.
• Choose a custom CRM if your records aren’t deals, outside people need their own logins, and seat fees across a large team keep climbing.
• Extend the CRM you already have if only one piece is missing, such as a portal, a quoting tool or an industry module.

The figures come from the vendors’ own pages, as of October 2026:

• Salesforce: Salesforce’s pricing page lists Starter Suite at $25 per user a month, Pro Suite at $100, Core at $195, Advanced at $395 and Max at $550. Every edition above Starter is billed annually, and Salesforce says most of its products use annual contracts.
• HubSpot: HubSpot’s Sales Hub pricing page lists Sales Hub Professional at $90 per seat a month billed annually, or $100 paid monthly on an annual commitment, and Sales Hub Enterprise from $150. The Starter tier is sold as the Starter Customer Platform, listed at $20 per seat a month and offered to new customers at $7 billed annually or $10 monthly. HubSpot’s Product & Services Catalog adds the required onboarding: $1,500 over 60 days for Professional, $3,500 over 90 days for Enterprise.
• Zoho: Zoho’s pricing page lists CRM Standard at $14, Professional at $23 and Enterprise at $40 per user a month billed annually, and a free edition for up to three users.

The three-year totals use the same assumptions as our custom CRM cost breakdown: annual billing at the prices above, HubSpot’s $1,500 onboarding included, and a hypothetical 880-hour custom build at $75 an hour with hosting and 15% yearly maintenance. That build is an illustration, not a quote. If you’d like to see a custom CRM in daily use while you compare, our CRM development page shows the one we run.

When is Salesforce or HubSpot the right choice?

Short answer: Salesforce or HubSpot is the right choice when your sales process looks like most companies’ (leads, deals, stages and follow-ups) and you need it running this month. It also fits a modest user count, or a team where nobody would own a custom system. That describes most small businesses.

We build custom CRMs and run our own, and our advice is plain: if one of the big products fits how you work, use it. If you’re still deciding whether you need a CRM at all, start with our 10-question self-check. The cases where buying wins are clear:

• Your process is standard. If your work is leads becoming deals becoming customers, these products are built around exactly that shape, and thousands of other businesses have already found the rough edges for you.
• You need it now. Salesforce offers a 30-day free trial of every Sales Cloud edition, HubSpot’s free tools cover up to two users at no cost, and Zoho’s free edition covers three. You can be entering real data this week.
• Your tools already connect. Salesforce’s AgentExchange and the HubSpot Marketplace list ready-made connections to other software, so check whether the tools you use are already there before you pay anyone to build a connection.
• You have few users. At 10 users, Salesforce Pro Suite lists at $12,000 a year and HubSpot Sales Hub Professional costs $10,800 a year with annual billing. A custom build is very unlikely to beat that over three years.
• Nobody would own it. A custom CRM needs a decision-maker on your side and a developer on call. Without both, buy.

You also get the vendors’ AI work without paying to build it, which matters more each year as both platforms add agents.

When does a custom CRM win?

Short answer: A custom CRM beats Salesforce or HubSpot when your work doesn’t fit a sales pipeline or when customers and partners need to sign in to their own records. It also wins when per-user fees grow with a large team, or when you need the data and access rules in a database you control. The case is strongest when more than one of these is true.

Your industry’s workflow isn’t a sales pipeline

Plenty of businesses track something other than deals. Our own CRM runs a dispatch operation, so its records are loads, carriers and drivers rather than deals and companies. Picture the rules that kind of work needs: a load that can’t be invoiced until its paperwork is in, or an invoice whose status has to update every load on it. You can model that in a big CRM, but you’re bending deals and custom objects into a shape they weren’t designed for, and in HubSpot, custom objects require an Enterprise edition.

Customers or partners need their own logins

Portals are where products differ most. HubSpot’s customer portal needs Service Hub Professional or Enterprise, and it’s built around support tickets. Salesforce’s pricing page lists its Partner Relationship Management add-on from $10 per login a month. Zoho’s Professional edition includes custom portals for customers, partners and vendors. A custom build can show each outside person exactly their own records; our own CRM has a carrier portal and a separate Owner Center for MC (motor carrier) owners.

Per-user fees add up with a large team

At 50 users, Salesforce Pro Suite lists at $60,000 a year and Core at $117,000; HubSpot Sales Hub Professional costs $54,000 a year with annual billing, plus onboarding. A custom CRM costs roughly the same whether 20 or 60 people sign in. Hosting and support grow a little with use, but there are no seat fees. On the three-year totals in the table above, the hypothetical custom build costs less than Salesforce Pro Suite from about 28 users and less than HubSpot Sales Hub Professional from about 31.

You want the data and the rules under your control

With a subscription CRM, your data lives in the vendor’s system and comes out through its export tools, on its schedule and limits. A custom CRM can keep everything in a standard database on a server you control. In ours, roles, teams and sharing rules are enforced in the database itself, and a custom build can run on your server or ours and be exported at any time.

Our take: One reason alone rarely justifies a build. An unusual workflow plus outside logins plus a team big enough for seat fees to sting is the pattern where custom clearly wins. If you only have one of those, try configuring or extending the product first.

What AI features do Salesforce and HubSpot include?

Short answer: Salesforce and HubSpot both now build artificial intelligence (AI) agents into the CRM. According to Salesforce’s Agentforce pricing page, Agentforce is sold through per-user add-ons, Flex Credits or per-conversation pricing; HubSpot’s Product & Services Catalog says every Core Seat includes Breeze Assistant and that agents run on monthly HubSpot Credits. A custom CRM can have AI features too, but each one is built for you and paid for per use.

Salesforce Agentforce

Salesforce describes Agentforce as an AI agent platform whose agents answer questions, take actions within set guardrails and hand issues to people when they fall outside their scope. Its pricing page lists Flex Credits at $500 per 100,000 credits, with a standard Agentforce action using 20 credits, a $2-per-conversation option, and Agentforce add-ons for Sales or Service at $125 per user a month. The Max edition includes the add-on and 2.75 million Flex Credits per org per year.

HubSpot Breeze and Agent Hub

HubSpot’s catalog describes Breeze Assistant as an AI assistant available throughout HubSpot, and its agents, such as the Prospecting, Data and Customer agents, are managed in Agent Hub and consume HubSpot Credits. Sales Hub includes 500, 3,000 or 5,000 credits a month at Starter, Professional and Enterprise; they reset monthly and don’t roll over. The Prospecting agent uses 100 credits per recommended outreach for one lead, and extra credits cost $0.010 each on pay-as-you-go.

Zoho and custom builds

Zoho’s pricing page lists AI agents and predictive intelligence in its Professional edition, and adds Zia’s extended AI capabilities in Enterprise. In a custom CRM, AI features are built one at a time, such as drafting replies, reading documents or summing up a record’s history, and you pay the AI provider for what you use.

Tip: Price AI by expected usage, not by the demo. Ask how many credits or actions your team would use in a normal month, and what happens when the included allowance runs out.

Can you extend Salesforce or HubSpot instead of replacing it?

Short answer: Yes, you can extend Salesforce or HubSpot instead of replacing it, and it’s often the best first step. Keep the CRM for the standard sales work and build a custom piece around it, such as a portal, a quoting tool or an industry module, that reads and writes through the CRM’s API (application programming interface).

This hybrid path works because both platforms are built to be extended:

• HubSpot lets developers build app cards that appear on CRM records, preview panels and the help desk and sales workspaces. HubSpot’s catalog lists API limits of 250,000 calls a day on Free and Starter, 650,000 on Professional and 1,000,000 on Enterprise, with an API Limit Increase at $500 a month adding 1,000,000 calls a day.
• Salesforce includes its Web Services API in Core and above and, on its pricing page, lists it at an additional $25 per user a month on Pro Suite; Starter Suite doesn’t include it. For systems without a built-in integration, Salesforce points to MuleSoft, its integration partners or AgentExchange apps.

The trade-offs are real. You maintain two systems instead of one, you still pay seat fees for everyone who uses the CRM, and a vendor’s change to its API or limits can break your extension. The hybrid path suits a narrow gap; once the custom part grows into most of what your team does every day, a full build is often the simpler system. Our guide to custom software vs off the shelf covers this middle path for software in general.

What should you ask about data export and migration?

Short answer: Before you sign any CRM contract, custom or subscription, find out how you’d get every record, file and piece of history out again, and how the new system would take it in. Those answers decide how hard any future move will be, whichever way you go.

Here’s what the vendors document:

• HubSpot record exports come as CSV, XLS or XLSX and can include all properties and associations, up to 300 exports in a rolling 24 hours. Activities such as calls and notes aren’t part of a record export, and download links expire after 30 days.
• Salesforce’s Data Export Service produces CSV files and can include images, documents and attachments if you select them. Trailhead says weekly exports are available in Enterprise, Performance and Unlimited editions, and every 29 days in Professional and Developer editions.
• Zoho module exports come as CSV or XLSX, and a complete backup includes all module data, attachments and configuration details.
• Imports have limits too. Salesforce’s Data Import Wizard takes up to 50,000 records at a time, with Data Loader for larger jobs; HubSpot’s catalog lists CRM imports of up to 50 a day and 500,000 rows a day.

Ask these questions of any vendor or developer:

1. Can we export every object, including custom objects, notes, emails, calls and files?
2. Do the links between records survive the export, and how?
3. How often can we run a full export, and can it run automatically?
4. Is the change history included, or only the current values?
5. For a custom build: is the database ours, on hosting in our name, with a documented structure?
6. How will migrated data be checked before we switch, and can old and new run side by side?
7. Will users keep their sign-ins? When we moved our own team off vTiger, everyone kept their old passwords.

Watch out: A CSV of your records doesn’t carry your workflows, automations, reports or permission rules. List them before any move, because each one has to be set up again in the new system.

Where to start

1. Write down the three to five things your current tools can’t do, and how much time each one costs a week.
2. Price your shortlisted product for three years at your expected user count, including onboarding and any API, AI, portal or support add-ons.
3. Ask the export and migration questions above before you sign, whichever way you’re leaning.
4. If the gap is narrow, try the hybrid path first: keep the CRM and build only the missing piece.
5. If you build, scope a small first version and budget yearly maintenance from day one.
