Structurell Tools

Get a Better Starting Point Before Making the Bigger Decision

Practical calculators and assessments for software, ecommerce and technical investment decisions.

You should not need a consultancy engagement just to ask a useful first question.

These tools help you test assumptions, understand where a problem may sit and identify the questions worth answering before committing more time or money.

Commercial decisions

Understand the Investment Before You Commit to It

Start with the commercial case. Work out what needs to be true for an investment to make sense and which assumptions have the greatest effect on the result.

B2B Ecommerce ROI Calculator

Model potential revenue contribution, operational savings, investment, payback and three-year return using your own assumptions.

Calculate B2B Ecommerce ROI

Technical Debt Cost Calculator

Estimate how much engineering capacity and operating cost may be getting consumed by technical friction, rework and difficult-to-change software.

Estimate Technical Debt Cost

Build vs Buy Calculator

Work through whether your requirement is better suited to off-the-shelf software, configuration and integration, or a custom build.

Compare Build vs Buy

Technical decisions

Understand What You Already Have

Use guided assessments to identify where deeper investigation may be worthwhile before committing to remediation or replacement.

Software Production Readiness Check

Assess whether an application has the basic security, testing, deployment, monitoring, recovery and ownership controls expected before real users depend on it.

Check Production Readiness

Rebuild or Improve?

Work through whether the evidence currently points towards targeted improvement, modernisation or a genuine rebuild.

Assess Your Platform

Useful, not definitive

These Tools Help You Ask Better Questions. They Do Not Pretend to Know Your System.

A calculator can test a commercial assumption. A questionnaire can highlight areas worth investigating.

Neither can inspect your code, understand your production environment or know why a particular technical decision was made.

Use the result as a starting point rather than treating an automated score as a technical verdict.

From question to decision

Use the Smallest Useful Step First

You may get everything you need from the tool. If it exposes a bigger question, there is a clear route to investigate further.

  1. 01

    Explore

    Use the calculator or assessment with the information you already have.

  2. 02

    Question

    See which assumptions or technical areas have the greatest effect on the result.

  3. 03

    Investigate

    If something material remains uncertain, use real evidence from the business or system to understand it properly.

  4. 04

    Decide

    Invest, improve, leave it alone or take another route with a clearer understanding of why.

Need more than the automated answer?

We Can Help Investigate What the Tool Cannot See

If the result raises questions about your actual software, platform or technical environment, Structurell can investigate the evidence and help work out what is genuinely worth doing next.
