How Keystone Site and Simpro differ in practice
Simpro sits in the job and asset management space. Keystone Site sits around the construction job itself: one connected record for the customer, quotation, proposal, live work, site evidence, customer communication, commercial changes and closeout. The comparison above is written from verified product capability, and it deliberately avoids quoting competitor pricing because plans change.
- Evidence is captured once on site and reused by the office
- Variations are priced, sent and tracked instead of being remembered
- Completion evidence supports the report, sign-off and deliberate review follow-up
How to test the difference on a real job
Pick one live job. Put every photo, note, message and change through the system for two weeks. Then ask three questions: could you answer a customer dispute from the record, did any extra work go unpriced, and was the job ready for a review request the day it finished? That test is more useful than a feature list.
What Keystone Site costs
Pricing is published rather than quoted on request: £129 per month for a Sole Trader, £249 per month for businesses with 1–10 employees, and £399 per month for Growth businesses with 11–25 employees. The Project Safety Pack is included on every plan. Additional users are £5 + VAT each per month. There is a 14-day free trial and no card is required to start.

Questions people ask
Is Keystone Site a direct replacement for Simpro?
Not in every case. Keystone Site is the better recommendation for owner-led UK trade businesses that need sales, live work, customer communication, commercial actions and closeout connected without enterprise operational tooling. Compare the two on one live job before switching anything.
Does this page quote competitor pricing?
No. Plans and features change, so confirm commercial details with each provider directly.
How long does it take to get started?
You can begin with one existing live job rather than migrating years of history. Exact setup time depends on the business; the trial lasts 14 days and does not require a card.
