When Does Replacing HubSpot or Salesforce With a Custom CRM Pay?

Replacing a CRM with a custom one pays off when you pay for many seats at a mid or high tier, but use only a small slice of the features, and your process is specific enough that you keep working around the SaaS. It does not pay off for a small team on a cheap plan, or when you rely on the vendor’s integrations, email tracking or compliance features. The break-even is simple arithmetic: build cost divided by monthly savings.

What do the big CRMs cost per seat?

Prices below are list prices as of November 2026, in USD, read from each vendor’s pricing page. Taxes are extra, and real contracts, especially at Salesforce, can be negotiated.

Product and edition	Per user per month	Billing	Source
HubSpot Sales Hub Starter	from $7 annual, $20 monthly	monthly or annual	HubSpot Sales Hub pricing
HubSpot Sales Hub Professional	from $90 annual, $100 monthly	annual commitment	HubSpot Sales Hub pricing
HubSpot Sales Hub Enterprise	from $150	not specified	HubSpot Sales Hub pricing
Salesforce Starter Suite	$25	monthly or annual	Salesforce Sales Cloud pricing
Salesforce Pro Suite	$100	annual	Salesforce Sales Cloud pricing
Salesforce Core	$195	annual	Salesforce Sales Cloud pricing
Zoho CRM Standard	$14 annual, $20 monthly	both	Zoho CRM pricing and comparison sheet
Zoho CRM Professional	$23 annual, $35 monthly	both	Zoho CRM pricing and comparison sheet
Zoho CRM Enterprise	$40 annual, $50 monthly	both	Zoho CRM pricing and comparison sheet

Extras to add to the picture:

HubSpot lists a one-time onboarding fee of $1,500 for Sales Hub Professional and $3,500 for Enterprise.
HubSpot Professional and Enterprise Sales Hub use paid Sales Seats, and view-only seats are free.
Zoho CRM has a free edition for up to 3 users.
Salesforce lists a Free Suite at $0.
HubSpot’s page does not label the Starter and Professional figures as monthly or annual in plain text, so I inferred the lower one is annual from its Pay Annually toggle. Confirm with the vendor before budgeting.

The pattern is clear: the big per-seat numbers sit at Professional and above. A 15-person team on Salesforce Pro Suite pays $1,500 a month list, which is $18,000 a year. The same team on Zoho CRM Professional at annual billing pays $345 a month, or $4,140 a year.

How do I calculate the break-even?

Use this formula:

Months to break even = build cost / (seats x SaaS price per seat - custom running cost per month)

Your inputs:

Seats: people who need to log in and edit. View-only users are often free or cheap, so do not count them.
SaaS price per seat: the real quoted rate, including add-ons you use.
Build cost: the fixed quote for the custom CRM. You fill this in. It depends on scope, so I am not putting a number on it.
Custom running cost per month: hosting plus your maintenance plan or the hours you spend on fixes. Assume this is not zero.

Here is a worked example with assumptions stated openly. These are illustrative, not quotes:

10 seats on HubSpot Sales Hub Professional at $90 per seat, annual billing, so $900 a month.
Custom running cost assumed at $100 a month (hosting and maintenance).
Monthly saving: $900 - $100 = $800.
HubSpot’s $1,500 onboarding fee is a sunk cost if you are already a customer, so I leave it out of the saving.

Build cost (you fill in)	Months to break even
$8,000	10
$16,000	20
$24,000	30

Rerun it with your own numbers. If you are on Zoho CRM Professional with 10 seats ($230 a month at $23 annual), the same $100 running cost leaves a $130 monthly saving, and an $8,000 build takes about 62 months, which is longer than most software stays unchanged. Cheap SaaS plans rarely lose to a custom build on cost alone.

A fair rule of thumb: if break-even lands beyond 24 to 36 months, the saving is not the reason to build. You would need another reason, such as workflow fit or owning your data.

What else belongs in the calculation?

Migration: moving contacts, deals, notes and email history. This is part of the build, so ask for it in the quote.
Your time: a custom CRM has to be specified. Someone on your side makes decisions during the build.
Price increases: SaaS list prices change. Salesforce’s pricing page states that its prices are for information only and subject to change.
Risk of a single builder: a custom tool needs documentation, source code access and a maintenance plan so you are not stuck.
Features you quietly use: email sync, calendar sync, mobile apps, reporting, role permissions. List them before you decide, and price each one in the custom scope.

When is the SaaS the better buy?

Stay on the SaaS when any of these is true:

You have few seats on a cheap plan. Zoho CRM’s free edition covers 3 users, and its paid editions start at $14 per user per month on annual billing. The break-even will not arrive.
You depend on the marketplace. If your process runs through dozens of vendor integrations, rebuilding them is the biggest cost in the project.
You need compliance or audit features that the vendor already has and maintains, and you would have to prove yourself in a custom system.
Your process is still changing. Customising a SaaS is cheaper than rebuilding custom code every quarter. Wait until the process stabilises.
You want marketing automation, email tracking and sales sequencing built in. These are the parts custom builds usually skip first.
You have no one to own it. Software without a maintainer degrades. If you will not pay for a maintenance plan or have no in-house person, the SaaS fee is partly paying for that.

When does custom pay off?

10 or more seats on a Professional or Enterprise tier where you use maybe a fifth of the features.
You already pay for add-ons and workarounds because the SaaS data model does not fit (jobs, projects, inventory, multi-step approvals).
You want your CRM tied directly to your own database, billing or operations tool, not synced through connectors.
The vendor’s per-seat model punishes you for adding field staff or part-timers.

In that situation I scope the smallest version first: contacts, deals, tasks and the two or three views your team actually uses, then add features once it is live.

FAQ

Is a custom CRM cheaper than HubSpot?

Only if the savings exceed the build cost within a period you accept. Use the break-even formula above with your seat count and plan.

Can I keep a free CRM tier and avoid building?

If you have 3 users or fewer, Zoho CRM’s free edition may be enough. HubSpot and Salesforce also offer free options, but check which limits matter for you.

What happens to my data if I cancel the SaaS?

Export everything before you cancel. Check whether your CRM can export, and that notes, attachments and activity history are included.

Who maintains a custom CRM afterwards?

You need a named person or a maintenance plan. Ask for source code, hosting details and documentation as part of the delivery.
