Build or buy software? A plain decision guide with real 3-year costs

What does build vs buy mean?

Buying means you pay for an existing product, usually a monthly subscription per user. People call this ready-made software or SaaS, short for software as a service. HubSpot, Pipedrive and QuickBooks are examples.

Building means you pay a team to make software for your business. You own it. You pay to build it once, then pay smaller amounts to host it and keep it running.

There is also a middle path. You can buy the core product and build a small custom piece around it. For many firms, that mix is the best answer.

When should you buy ready-made software?

Buy when most of these are true.

• Your process is standard: You sell, bill or book in the way most businesses in your field do.
• Your team is small: Per-seat fees for 5 or 10 people are easy to justify.
• You need it this month: A product works on day one. A custom build takes time.
• The vendor does the hard parts: Payroll tax, payments and accounting rules change often. Let a vendor keep up with them.
• Nobody owns the project: A custom build needs someone on your side to make decisions. If you have no time for that, buy.

For payroll, accounting and payments, almost every small business should buy. Those tools carry legal and tax rules that are costly to rebuild.

When does custom software make more sense?

Build when one or more of these are true.

• Your workflow is unusual: The way you quote, schedule or deliver is part of why customers pick you, and no product fits it.
• Your tools do not talk: Staff copy the same data between three or four apps every day.
• Per-seat fees grow fast: Your team is growing, and the bill grows with every hire.
• You must control your data: Clients or regulators expect you to know exactly where data lives and who can see it.
• You need deep links to your own systems: The software must work closely with your job system, database or customer app.

How does the cost compare over 3 years?

The table below shows what three CRMs cost over 36 months at different team sizes. Each price below is from the vendor's own pricing page in October 2026, shown in US dollars. The HubSpot Professional and Pipedrive prices are for yearly billing.

• HubSpot Sales Hub Professional: $90 per seat a month, plus a required $1,500 onboarding fee.
• HubSpot Sales Hub Enterprise: $150 per seat a month, plus a required $3,500 onboarding fee.
• Pipedrive Premium: $59 per seat a month.
• Twenty Organization: $19 per user a month. Twenty is an open-source CRM.

Plan	10 seats, 3 years	25 seats, 3 years	50 seats, 3 years
HubSpot Sales Hub Professional	$33,900	$82,500	$163,500
HubSpot Sales Hub Enterprise	$57,500	$138,500	$273,500
Pipedrive Premium	$21,240	$53,100	$106,200
Twenty Organization	$6,840	$17,100	$34,200

These totals assume prices stay the same for three years. They leave out add-ons, extra usage and tax. Your real bill may be higher.

What does a custom build cost to run?

A custom web app has three costs: the build, the hosting and the care after launch.

Hosting can be small. For example, Vercel's Pro plan is $20 a month for one developer seat, and Supabase's Pro plan starts at $25 a month, as of October 2026. That is $1,620 over three years before extra usage. Both charge more if you use more than the plan includes. The hosting bill does not grow with each staff member you add, the way per-seat fees do.

The build and the care depend on what you need, so get a written quote. Then compare like this.

1. Work out the subscription total: Use the table above, or your own tools, for three years.
2. Add up the custom total: Take the build quote, add three years of care, and add hosting.
3. Compare the two: If the custom total is lower, building pays off within three years. After that, you keep the software.
4. Add the hidden costs: Count the hours your staff lose to workarounds today. Count your own time to plan a build.

For example, a 25-person sales team on HubSpot Sales Hub Professional would pay $82,500 over three years. A custom CRM that costs less than that to build, care for and host would save money. A 10-person team on Twenty would pay $6,840, and almost no custom build beats that on cost alone.

My guide to custom software development cost explains what drives a build quote.

What hidden costs come with each choice?

Both paths have costs that do not show on the price tag.

Hidden costs of buying

• Price rises: Vendors can raise prices or move features to higher plans.
• Add-ons: AI features, extra contacts or more automations often cost extra.
• Workarounds: Staff time spent fixing data by hand is a real cost.
• SaaS sprawl: Many tools with overlapping features, each with its own login and bill.
• Exit cost: Moving data out later can be slow and messy.

Hidden costs of building

• Your time: Someone in your business must explain the work and test each version.
• Time to launch: You wait weeks or months for the first version.
• Upkeep: Software needs updates, security fixes and backups. Budget for care every month.
• Builder risk: If the team keeps the code or the accounts, you are stuck. Make sure you own both.

What is SaaS sprawl and how do you fix it?

SaaS sprawl means a business pays for more software subscriptions than it needs. It happens slowly. Each team adds a tool for one job, and nobody looks at the full list.

Fix it in an afternoon.

1. List every subscription: Check your card statements and accounting tool.
2. Note seats and cost: Write down how many people use each tool and the yearly total.
3. Mark overlaps: Circle tools that do the same job, such as two project tools or two form tools.
4. Cut or combine: Cancel unused seats first. Then join overlapping tools into one.
5. Look at the gaps: If you keep a tool only to link two others, a small custom tool may replace it.

Should you use a self-hosted or customizable CRM?

A self-hosted CRM runs on servers you control. Open-source products such as Twenty let you self-host the core for free. You still pay for hosting, and someone must install updates, run backups and keep it secure.

A customizable CRM is a product that lets you add your own fields, stages and screens. Most CRMs allow some of this. Before you buy, test one real workflow end to end. If it needs many workarounds, a custom tool may be simpler. My page on HubSpot alternatives compares other CRMs, and my guide to CRM for small business covers when to build one.

How Blur Studio approaches build vs buy

When a client asks me to build, I first check whether they should buy. I map the workflow, list their current tools and run the three-year numbers with them. Sometimes the answer is a better setup of a tool they already pay for, and I tell them that.

When custom wins, I often keep the products that do their job well, such as payroll and accounting. I then build the missing piece around them. Clients keep full ownership of the code and every account. I take care of the software after launch, so it keeps working as the business grows.

Need something completely custom?

Everything above is a path to get it running quick and cheap. But sometimes the honest answer is that none of those quite fit, and what you actually need is something custom that you own, built uniquely for your business from the ground up, with AI thoughtfully designed into the parts of it that your processes actually benefit from. An asset that grows in value, not a generic, one-size-fits-all boilerplate that's an expense with a lock-in. This is a complete bespoke build, and it's something I do very well.
