Everything the job file needs
Site evidence and commercial control in the same system — for UK construction companies who are done with a pile of apps.
On site
What the site team needs every morning — without hunting phones and inboxes.

Site diary
Daily progress, weather, labour and photos — timestamped for disputes and insurers.
Drawings & documents
Latest revisions on the job, not lost in email threads or WhatsApp.
Health & safety
RAMS, inductions and toolbox talks tied to the project they belong to.
Snags & tasks
Raise, assign and close defects with photos before handover.
Commercial
The money side of the job, kept next to the work that caused it.

Variations
Capture client changes with cost and status so extras do not vanish.
Invoicing & retention
Applications, payment notices and retention tracking for UK contracts.
CIS
Subcontractor status and statements where the site team can see them.
Purchase orders
Orders and suppliers linked to the job — not a separate spreadsheet.
Office & clients
Roles, portals and reports so the office is not reinventing the job every week.

Team roles
Owner, office, site and view-only access so the right people see the right things.
Client portal
Share progress and quotes without giving away your whole job file.
Reports
VAT, aged debtors and cost views for month-end without hunting files.
Audit & export
Who changed what, plus GDPR-friendly data export when you need it.
