Simpro

What Simpro is

Simpro is aimed at contractors who run both project work and service work, which is a genuinely awkward combination for most software. It carries real estimating with supplier catalogues, multi-stage project management with progress claims, inventory across stores and vans, and maintenance planning — the kind of depth commercial electrical and mechanical contractors need.

What it does well

• Handles project work and service work in one system
• Supplier catalogue pricing in estimates
• Multi-location inventory with van stock
• Strong work-in-progress and project cost reporting

Integrates with

QuickBooks · Xero · Sage · Supplier catalogues

Integration lists change often and "integrates" can mean anything from a real two-way sync to a one-way push through Zapier. Ask the vendor which fields move, in which direction, and how often.

Before you commit

• Run one real job end to end during the trial — quote, schedule, invoice, payment. Demos hide friction; a real job does not.
• Check the mobile app on your own phone, outdoors, on cell data. That is where your crew will actually use it.
• Confirm the accounting sync is two-way and that it maps to the way your bookkeeper already works.
• Ask what happens to your data if you leave. Export formats matter more than you think on day 400.
• Price it at the headcount you expect in 18 months, not today — per-user pricing is where budgets break.

How to judge it in a trial

Run one real job through it end to end — not the demo data. Quote it, schedule it, do it, invoice it, take the payment. Then ask the only question that matters on day 400: did the people who have to use this every day find it faster than what they do now? Friction you notice in week one compounds forever, and tool-hopping costs more than any feature gap.
