Inputs

People and rates

Core

Field engineers

Headcount used for utilisation savings.

Office staff

Used for admin time savings.

Average engineer billable day rate

Use blended rate across labour lines.

Admin loaded hourly cost

Wages + NI + overhead (simple estimate).

Working weeks per year

Default assumes holiday and downtime.

Simpro investment

Cost

Monthly subscription

Enter the proposal figure (ex VAT).

One-off implementation

Initial rollout and configuration (ex VAT).


Contract length (months)

Used for total cost and multi-year ROI views.

Tip: Promotions reduce free months and/or implementation. Multi-year terms also apply a 3% annual uplift (CPI-style) to subscription in years 2 and 3.

Value levers

Where the ROI comes from

Recovered engineer time (hours per engineer per week)

Scheduling visibility, fewer gaps, less admin back-and-forth.

Margin recovered (% of annual install revenue)

Visibility on labour/material drift, better project control.

Annual install revenue

Only include the part where margin leakage is a risk (projects/installs).

Admin time saved (hours per office staff per week)

Less re-keying, fewer phone calls, faster invoice prep, cleaner workflow.

Invoice delay reduced (days)

Progress billing and faster job completion admin.

Average monthly invoicing

Used to estimate cash position uplift. (This is not profit, it is cash timing.)
