Build or buy: LeanSuite vs homegrown software

Short answer: Buy, unless the process is truly unique to your business and a development team, not one person, will own the tool for years. An in-house tool is cheap to build and costly to keep: every change, security question, mobile app and handover lands on the person who built it. Buying gets you a product team, regular releases and support.

For plants whose ideas, kaizen, audits or daily issues run on a tool someone inside the company built: an Excel workbook with macros, an Access database, a SharePoint list, a Power App or a small web app.

Build or buy: the quick verdict

Build your own if

  • The process is truly unique and no product models it.
  • A development team, not one person, will own it for years.
  • It must live inside systems only your developers can reach.
  • The scope is small and stable: one area, a few users.

Buy if

  • One person built it and one person maintains it.
  • Changes wait in their queue and side spreadsheets appear.
  • Operators can't use it on the floor.
  • A second shift or plant wants it.
  • IT or a customer asks security questions nobody can answer.

What an in-house tool really costs

The build is the part you see. Most of what follows lands on the person who built it.

Above the waterline

The build

What usually gets budgeted

Below the waterline: what arrives later

  • One person holds the knowledge

    Why each column and macro exists is rarely written down.

  • Every change waits in one queue

    Every new field, step, report and plant waits for the same person.

  • Security, access and hosting are a side job

    Users, patches and backups have no owner until an auditor asks.

  • No mobile app unless someone builds one

    Operators without a PC or email go through a supervisor or paper.

  • Reports break when the builder leaves

    Rename a column or move a file and the numbers stop updating.

  • Migrations land on your team

    A retired server or a second plant is a project for your people.

How each path plays out

In-house tool

  1. Someone builds it, usually alongside their day job.

  2. It works while that person is there and has time.

  3. Changes queue up and side spreadsheets appear.

  4. The builder moves on, and nobody can change the tool.

LeanSuite

  1. Our team sets LeanSuite up and trains your core team.

  2. Your first module is typically live in under a week.

  3. Onboarding runs for 90 days with regular check-ins.

  4. New features ship in regular releases, with release notes in the help center.

In the demo

  1. An operator scans a QR code and adds a photo, the issue reaches its owner by rule with a due date, and a repeat issue becomes a Kaizen in one click.
  2. A kaizen event, an A3 and an engineering or CapEx project in the same system, each through its own workflow, run as DMAIC, PDCA, 8D or your own method.
  3. Operators signing in with an employee ID on a phone or shared tablet, with no company email needed.

Want to run LeanSuite on your own lines instead? The 90-day pilot is $3,000 per facility, set up by our team, with the first module live in under a week.

FAQ

Build vs buy: common questions

  1. Buy, unless the process is truly unique and a development team will own the tool for years. A CI tool needs changes, security, hosting, a mobile app and support, and in-house that usually falls on one person. LeanSuite includes ready-made modules, a product team and support.

  2. Keep the old tracker as a read-only archive. In LeanSuite, KPI values can be uploaded as a CSV with column mapping or pulled on a schedule from Excel and Google Sheets, and Lean AI turns uploaded Excel or PDF checklists into digital ones. Our team does the setup.

  3. Export the data and list what the tool does today: the fields, the approval steps and the reports people still use. That list is your requirements, whether you rebuild or buy. If nobody can own the tool for years, run the process in a product for 90 days.

  4. Yes. Send it to support or your customer success manager with a real example from your site. The product team weighs requests for the roadmap. LeanSuite doesn't promise to build any particular request or give a date for one, and doesn't do custom one-off development.

  5. Count the upkeep, not just the build: the builder's hours, hosting and backups, user access, security reviews, a mobile app, and rescuing the tool when the builder leaves. Compare that with a per-facility price. LeanSuite's 90-day pilot costs $3,000 per facility.
