The complete job lifecycle

Four outcomes. One connected operating record.

Keystone is organised around what an owner needs the business to achieve—not a list of disconnected software features.

WIN01

Win work with a stronger commercial record.

Keep the customer, enquiry, quotation and proposal connected. Build a professional offer from the job and the pricing information your business already trusts.

  • Customer records and enquiries
  • Itemised quotes and revisions
  • Project-specific proposals
  • Commercial history and pricing knowledge

RUN02

Run the job without turning installers into administrators.

Give the crew a simple place to see assigned work, capture site truth and find the files they need. Give the office a live job record, calendar and clear operational context.

  • Jobs and assignments
  • Mobile photos, notes and files
  • Calendar and timesheets — developing
  • Safety packs and acknowledgements

GET PAID03

Protect cash before extra work disappears.

Track commercial decisions against the job. See what needs pricing, what is waiting for a customer and what approved work still needs invoicing.

  • Variations and customer decisions
  • Commercial Control
  • Approved work waiting for invoicing
  • Completion and accounting handoff context

GET REFERRED04

Close the job properly—and make the proof work again.

Turn a complete job record into a customer-facing report, sign-off, well-timed review request and reusable marketing proof.

  • Completion reports and sign-off
  • Review requests and tracking
  • Marketing assets from finished work
  • Reusable job proof for the next proposal

A useful morning in Keystone

Start with the decisions that move the business.

Morning Briefing brings cash blockers, customer risks, stalled jobs and closeout opportunities into one calm starting point.

Keystone intelligence

It does more than show you what happened.

Keystone turns reliable job facts into management actions. The rules work without AI; AI is used selectively to help draft and explain, with the office still in control.

These are admin-facing summaries, not a replacement for the factual job timeline. Their depth depends on the reliable records held in the workspace.

Morning BriefingKeystone PrioritiesJob IntelligenceProject HealthBusiness MomentumCustomer ConfidenceCommercial ControlDecision Engine

Where is cash blocked?

Commercial Control surfaces unpriced, awaiting-decision and approved-but-uninvoiced work.

Which customer needs an update?

Customer Confidence flags silence, waiting decisions and closeout communication.

Which job has stalled?

Business Momentum and Project Health explain the blocker and the next useful action.

What should I deal with first?

Keystone Priorities ranks actions by cash, customer risk, progress and reputation.

One job, one connected record

Follow a rear extension from enquiry to review.

Each stage uses the same customer and job context. Keystone records the facts and makes the next action clear without pretending every transition is automatic.

  1. 01

    Enquiry recorded

    Customer and job context start together.

  2. 02

    Quote prepared

    Itemised pricing, VAT, margins and revisions stay in the commercial record.

  3. 03

    Proposal issued

    The chosen quote version supports a polished, project-specific proposal.

  4. 04

    Customer decides

    Proposal acceptance or decline is recorded; an admin explicitly activates accepted work.

  5. 05

    Site work captured

    Installers add photos, notes, files, check-ins and safety acknowledgements to the job.

  6. 06

    Customer kept informed

    The office chooses and sends traceable progress updates from reliable job facts.

  7. 07

    Changes controlled

    Variations are priced, sent and recorded against the job decision.

  8. 08

    Job closed properly

    Completion evidence, report, sign-off, review and marketing proof remain connected.

Capture once
Use it everywhere it belongs
Bring the site into the office

The installer captures site truth. The office puts it to work.

Keystone keeps the field experience deliberately simple. Installers see assigned jobs, capture evidence and access what they need. Customer and commercial work stays with authorised office users.

Photos and evidence

Fast, job-aware mobile capture.

Files and drawings

The right documents stay with the job.

Safety

Packs and acknowledgements remain attached.

Office communication

Notes and job chat keep the team aligned.

Capture once. Use it everywhere.

Reliable site information can support office updates, variations, safety, commercial follow-up, completion, reports, reviews, marketing and management decisions—through the relevant controlled workflow.

Commercial control and estimating

Use the commercial knowledge already inside the business.

Keystone brings quotes, variations, supplier evidence and working prices closer to the job. The goal is better judgement and less retyping—not a black-box price generator.

1

Quoting

Create itemised quotes with VAT, margins, revisions and a retained commercial history.

2

Proposals

Use an existing quotation as the commercial source for a project-specific customer proposal.

3

Costs and evidence

In the specialist admin workflow, upload supported supplier invoices, review extracted lines and decide what should contribute to pricing knowledge.

4

Price Book and Cost Book

Admin users can work from an explainable, supplier-aware commercial view with visible manual overrides.

5

Estimating—early access

Suggestions and assemblies exist, but the specialist estimating workflow remains limited and is marketed as early access.

Keystone workspace

Human confirmation matters

Extracted invoice lines and pricing suggestions remain reviewable commercial inputs.

Evidence stays traceable

Working prices do not replace the source invoices, quotes and decisions behind them.

A clear boundary

Keystone runs the job.

Customers, offers, site work, variations, evidence, completion and the actions around them stay connected.

Your accounting software handles the accounts.

Keystone is not bookkeeping, payroll or a replacement for specialist accounting software. Wider system connectivity depends on the configured integration workflow; no native Xero integration is claimed.

Where the problem often starts

WhatsApp is useful. It is not a proper job record.

Photos, decisions, voice notes and customer conversations become hard to reconstruct when they are scattered across chats and phones. Keystone gives the work one connected record.

Scattered
  • Photos on different phones
  • Changes agreed in chat
  • Office chasing for context
Connected
  • Evidence against the job
  • Decisions in the timeline
  • Clear office follow-up

A controlled WhatsApp import can bring selected exported job history into an existing job after review. It does not connect to a personal WhatsApp account.

Built for the people running the business

Practical software for small and growing UK construction teams.

Keystone suits owner-led businesses where the office needs control and the crew needs speed. It is not an enterprise planning suite and it does not ask installers to become project administrators.

Straight answers

What construction owners ask first.

Clear product boundaries are part of the promise.

What is Keystone Site?+

Keystone Site is construction business software built around the job. It connects customers, enquiries, quotations, proposals, site activity, customer communication, variations, completion and the owner actions that follow.

Is Keystone just for site photos and reports?+

No. Site evidence is an important factual input, but Keystone also includes customer records, commercial workflows, jobs, scheduling, communication, safety, closeout, reviews, marketing proof and owner-facing intelligence.

Does Keystone replace accounting software?+

No. Keystone runs the operational job record. It is not bookkeeping, payroll or a replacement for specialist accounting software. Any wider accounting handoff depends on the configured business integration workflow.

Can customers accept a quote?+

Keystone can use a quotation as the commercial source for a customer proposal. The proposal is the customer decision surface, and an admin then explicitly activates accepted work. Keystone does not claim that viewing a quote PDF automatically starts a live job.

What does the installer need to do?+

Installers use a mobile-first view to open assigned jobs, capture photos and notes, access files, acknowledge safety information and communicate with the office. Customer and sensitive commercial work stays with authorised office users.

Can I see the product before signing up?+

Yes. The live demo is an ungated sample workspace with realistic, clearly labelled construction data. You can inspect it before starting a trial or speaking to anyone.
