Buy or Build? Everyone Answering Has a Bias

Ask a SaaS vendor and you should buy. Ask a development agency and you should build. Both have invoices riding on the answer — so here's a framework instead, five questions that decide it case by case.

Question 1: Is Your Process a Commodity or an Advantage?

Accounting, payroll tax filing, email — these are commodity processes. Yours doesn't differ meaningfully from other companies', and it shouldn't. Buy. The market has refined these tools over decades.

But the process that makes customers choose you over competitors — your quoting logic, your fulfillment speed, your client experience? Forcing that into generic software means sanding off exactly what made it an advantage. Build.

Rule of thumb: buy for parity, build for advantage.

Question 2: How Much Are Workarounds Costing You — Really?

Off-the-shelf software that almost fits generates invisible costs:

• The spreadsheet someone maintains to bridge two systems
• The 40 minutes daily of copy-paste between tools
• The errors when the workaround breaks and orders fall through
• The report that takes a day each month to assemble by hand

Track these for two weeks and price them at loaded salary cost. Teams are routinely shocked: "almost fits" often costs more per year than building the right tool once.

Question 3: What Does the Subscription Cost at 3× Your Size?

SaaS pricing is per-seat and per-tier. Model your bill at three times your current team and volume. That Rp 2 million/month tool at 10 users is Rp 72 million/year at 30 users — every year, forever, with annual price increases on top.

Custom software inverts the curve: build cost up front, then marginal cost near zero as you grow. For stable, high-usage workflows, the crossover typically arrives in 18–36 months.

Question 4: How Many Systems Must It Talk To?

One standalone tool? Buy. But if the workflow spans your CRM, your invoicing, your warehouse, and WhatsApp — integration is where off-the-shelf dies. Pre-built connectors cover the popular pairs; everything else means manual re-entry or fragile no-code chains.

Custom software treats integration as a design requirement: one system that connects what you already use, instead of a sixth tool that needs five more connectors.

Question 5: Who Owns the Data and the Roadmap?

With SaaS, features arrive when the vendor's roadmap says so, prices change when their investors say so, and your data lives behind their export button. Usually acceptable. Sometimes not — particularly for the system at the core of your operations.

With custom software you own the code, the data, and the priority list. When your business changes, the software changes with it — in your timeline.

The Scorecard

Count your answers:

• Commodity process, low workaround cost, flat scaling, standalone, low ownership stakes → buy with confidence
• Differentiating process, expensive workarounds, painful scaling math, heavy integration needs, core-system stakes → build
• Mixed? Buy for now, design the workflow so data can migrate later. The most expensive mistake isn't choosing wrong — it's choosing accidentally.

A Realistic Middle Path

Custom doesn't mean replacing everything. The most successful projects we deliver are focused: one bottleneck, one workflow, 4–8 weeks. Keep your accounting SaaS; build the quoting engine that feeds it.
