# Build or buy? Start with the workflow

> Software price is only one line in the decision. Integration work, failures, maintenance, and the cost of leaving matter too.

## In brief

- Name the business constraint before comparing products.
- Count maintenance, failures, and exit work as well as the subscription.
- If only one part is special, build that part and buy the rest.

## There are more than two choices

Build or buy sounds tidy, but most teams have at least four options. They can buy a complete product, configure a platform, connect several services, or write one custom component around familiar infrastructure.

Start with the constraint. Are you short on time? Do you need more control? Is the workflow part of the company's advantage? Are compliance, reliability, or cost at scale the real concern? Two similar workflows can deserve different solutions.

## 1. Is this where the company wins?

Buy the ordinary parts and keep control of the distinctive part. Payroll, password resets, and invoice delivery are rarely sensible places for a small company to invent infrastructure. A qualification method, knowledge layer, or customer handoff may be different because it captures how the company works.

Be strict about that distinction. A spreadsheet is not strategic just because it has become complicated.

## 2. Count the cost after launch

The subscription is visible, so it attracts too much attention. Add setup, integration maintenance, monitoring, vendor management, training, migration, and the cost of failures.

For custom software, ask who will own it after the original developer leaves. For a purchased product, count the manual workarounds needed when an important rule does not fit.

## 3. Imagine the failure first

What happens when the tool goes down, changes its API, loses a record, or makes a decision nobody can explain? Severity and reversibility can tell you more than a long feature table.

CISA's Secure by Design guidance asks technology producers to make products secure by default. A buyer should still check how access, logs, updates, and incident response work in the version they will actually use.

## 4. Find out how you would leave

Some tools are cheap to enter and painful to replace. Inspect export formats, API access, identity and domain ownership, retention rules, and the amount of business logic trapped in proprietary configuration.

With custom software, keep the source, deployment, domains, and service accounts under company control. Planning an exit is simply checking whether the company still owns the operation.

## 5. Keep the custom part small

One unusual decision inside a workflow does not require a whole new platform. Buy identity, hosting, monitoring, and common integrations. Build the narrow rule or interface that matters to the business.

There is less to maintain, and replacing the surrounding services later becomes much easier.

## Put the decision on one page

Score the serious options from one to five for strategic fit, time to launch, three-year operating cost, security, integration effort, reliability, internal skill, and exit cost. Decide the weight of each item before looking at vendor scores.

Now imagine the leading option failed eighteen months from today. Write the three likeliest causes. If the scorecard does not reflect them, change the weights and run it again.

You will not predict every future requirement. You can still make today's tradeoff clear enough to revisit when the facts change.
