Commercial ROI Calculator

Built around Kilbury’s key levers: labour capture, variations, admin capacity, invoicing speed and department margin visibility. Conservative by default, tweakable when you want to get spicy.

Commercial, Implementation & Support Overview
Summary of Simon’s questions with clear Simpro responses, so everything sits in one place before reviewing the ROI.
Commercial & cost structure
  • Up-front purchase vs subscription
    Simpro is a subscription-based platform. There is no perpetual or one-off licence with minimal monthly fees. Hosting, security, support, integrations and ongoing product development are all included within the subscription.
  • True net running costs
    Baseline (non-promotional) costs based on current requirements are £770 per month (£9,240 per annum) plus a £3,000 one-off implementation.
  • Budgeting and future costs
    Costs scale only with user numbers. For 24 or 36 month contracts, an annual uplift of the higher of 3% or CPI applies. There are no hidden platform fees and optional add-ons or services are discretionary.
  • Long-term commitment
    Standard entry is 12 months, with longer terms optional. There is no lifetime lock-in. Licences can be increased during the term and reduced back to the contractual baseline at renewal.
ROI & value justification
  • How value is delivered
    Simpro replaces spreadsheets, duplicate data entry and fragmented reporting. Tangible gains typically come from faster invoicing, earlier visibility of overruns, reduced admin effort, and less reliance on accounts for operational insight.
  • Change impact reality
    Not all staff adapt instantly. There is an initial learning curve, with productivity gains increasing progressively rather than immediately. Simpro supports staged adoption to manage this.
  • Benefit vs disruption
    The objective is controlled improvement with measurable gains, not short-term disruption for its own sake.
Implementation & change management
  • Implementation approach
    Consultant-led and structured: workflow mapping, system configuration aligned to Kilbury’s divisions, core data setup, user training, go-live support and handover.
  • Parallel running
    A parallel run of up to 3 months is realistic and common. Duplicate systems during this period are expected.
  • Cutover timing
    A clean cutover around 1 April aligns well with financial reporting and benchmarking.
  • Data and integrations
    QuickBooks integration is included. Core data is set up during implementation. Historical data usually remains in legacy systems unless there is a strong commercial reason to migrate it.
Support & training
  • What the subscription includes
    Just under 24/6 in-house support (12 hours UK, 12 hours Australia), phone and ticketed support, knowledge base, training materials, platform updates and security.
  • Training delivery
    Consultant-led implementation with online delivery by default. Onsite training is available if required, subject to scheduling and cost.
  • Engagement model
    This is not a self-serve model. The rollout is guided and structured.
Licensing & contract flexibility
  • Licence types
    Office licences are concurrent. Mobile licences are per named user.
  • Flexibility
    Licences can be increased mid-term and right-sized at renewal. Short-term increases are supported.
  • Contract terms
    Standard entry is 12 months. Longer terms are optional, not mandatory, with flexibility at renewal.

Tips:
  • Keep the inputs conservative for first-pass credibility.
  • Use the confidence sliders to reflect “culture change” reality.
  • If the numbers look too good to be true, they probably are. Reduce assumptions until it feels boring.
