The Short Answer
- Under $500/month for a workflow: buy. SaaS is cheaper to start, maintain, and update.
- $500 to $1,500/month: audit first. Build only if the workflow is highly specific and SaaS imposes constraints you cannot work around.
- Over $1,500/month: a custom build typically pays for itself in 12 to 18 months, then you own it with no recurring fees.
- Over $3,000/month (HubSpot Enterprise, Salesforce Unlimited): custom pays for itself in 6 to 12 months.
A client asked me last month whether they should keep paying $890 a month for HubSpot Professional or build their own CRM. That is the $80K question, because over a typical engagement that HubSpot contract (plus the mandatory $3,000 onboarding and seat add-ons) runs close to $80,000. The honest answer was not “build” or “buy.” It was a number. Here is how to find yours.

The Spend Threshold Where Building Beats Buying
The decision tips on combined recurring cost for a single workflow. Not your whole software bill, one workflow (your CRM, your booking system, your email automation). Here is the framework, ordered by monthly spend.
← Swipe to see full table →
| Monthly spend | Decision | Why | Payback if you build |
|---|---|---|---|
| Under $500 | Buy | SaaS cheaper to start, maintain, update | Never worth it |
| $500 to $1,500 | Audit first | Build only if workflow is business-specific + SaaS constrains you | 18 to 30 months |
| $1,500 to $3,000 | Build (usually) | Custom pays off, you own the code | 12 to 18 months |
| Over $3,000 | Build | Cost is decisive; integration depth is the real question | 6 to 12 months |
The math compounds when the SaaS uses per-user, per-contact, per-transaction, or usage-based pricing, because those models scale fastest with your growth. A custom build's cost stays flat. A SaaS bill at 12% annual inflation (the 2026 Vertice figure) roughly doubles in five years. By year five the SaaS path costs about 2x your current annual spend; the custom path costs $0 incremental beyond hosting.
The CRM Example: Custom vs HubSpot vs Salesforce
CRM is the workflow I get asked about most, so here is the real math. A custom Next.js CRM with the specific pipeline stages, automations, and integrations a business actually uses typically costs $15,000 to $40,000 one-time. Against the three most common SaaS CRMs:
- ✓GoHighLevel ($97 to $497/month): custom breaks even between year 3 and year 7. GHL is cheap enough that the case for building is weakest here unless you need something GHL cannot do.
- ✓HubSpot Professional ($890/month plus mandatory $3,000 onboarding, year-one total ~$13,700): custom breaks even between year 2 and year 3. This is the classic build case.
- ✓Salesforce Enterprise ($175/user/month): for a team of 10 that is $21,000/year. Custom breaks even within year 1. For any team of 5 or more, the math favors building.
"The question I ask every client is not “can we build this?” We almost always can. The question is “does this workflow cost you more than $1,500 a month and is it specific to how your business runs?” If yes to both, building is usually the cheaper path within two years and you own it forever after.

The AI Caveat: Why Cheap-to-Build Is Not the Same as Build-It-Yourself
AI-assisted development is the main reason the build-versus-buy math flipped in 2026. Paired engineering with tools like Claude and Cursor collapses build timelines from 12 months to 4 to 8 weeks for many internal tools. That is real, and it is what makes fixed-price custom builds viable at all.
But there is a trap. Gartner predicts that by 2028, unsupervised prompt-to-app and citizen-developer approaches will increase software defects by 2,500%, triggering a quality crisis because the generated code is architecturally unsound and far costlier to fix later. Source: Gartner Predicts 2026. AI accelerates a skilled engineer. It does not replace one. The cheap path (an unsupervised AI builder) produces a mockup that breaks in production. The professional path (AI-accelerated engineering with human review) is what delivers software you can actually run a business on. We cover this trap in detail in our guide to hiring cheap web developers without getting burned.
When Buying Still Wins (Be Honest About This)
Building is not always right, and I tell clients when it is not. Buy when:
- ✓Combined recurring cost for the workflow is under $500/month.
- ✓The tool is commodity functionality with no business-specific logic (basic email, file storage, video calls).
- ✓You have fewer than five users.
- ✓The vendor is doing genuinely hard engineering you could not replicate cheaply: payment processing (Stripe), email deliverability infrastructure (the actual sending reputation, not the UI), real-time video.
- ✓Speed-to-launch matters more than ownership and the tool is not a core competitive workflow.
The mistake is not buying when you should build. The mistake is staying on SaaS by default for a high-spend, business-specific workflow where custom would pay off within 18 months, simply because switching feels like effort. When you find a workflow over $1,500/month, run the math. The step-by-step audit is in how to cut your SaaS bill 40 to 70%, and the full list of 2026 price increases pushing this decision is in our 2026 SaaS price increase tracker.
