Honest comparison
Chime Software and Site Control solve different ends of the same site. Chime excels at subcontractor time & attendance — GPS clock-in flowing into automatic CIS payroll, plus asset tracking. Site Control is built for the principal contractor running the site: it generates UK RAMS, CPP and COSHH documents, runs RFIs, gates inductions, and isolates each contractor company's data. Choose by who you are.
Chime is the stronger pick for subcontractors who need GPS clock-in and CIS payroll; Site Control wins for a principal contractor who must generate RAMS, run RFIs and isolate each contractor's data on one site.

Pricing, fit, and feature coverage side by side.
| Feature | The Site Book Site Control | Chime Software |
|---|---|---|
| Pricing | From £675/site per month plus £5,000 one-off setup; volume tiers as sites scale | Quote-only — no public per-user figures; ROI calculator on site, talk to sales |
| Team size | Per active site with unlimited workers (~75+ typical); multiple contractor companies per site | Best for growing subcontractor firms with payrolled and CIS workforces, from roughly 20 operatives upward |
| Best for | Principal contractors and builders running live sites with subcontractors who need UK CDM documents generated plus on-site contractor access, attendance, RFIs and audit-ready evidence in one per-site tool. | Subcontractors and labour-heavy trades digitising timesheets, CIS payroll and field workforce management across multiple sites |
| Not ideal for | No biometric turnstiles or physical access control, so it cannot secure a Tier-1 perimeter the way hardware-led platforms like MSite can. | Distributes RAMS rather than generating them — no built-in UK RAMS/CPP/COSHH document creation, so the compliance pack still has to be authored elsewhere. |
| RAMS / CPP / COSHH generation | Generates UK RAMS, CPP, COSHH and method statements from the project brief — unique in this category. | |
| Permits to work | Document distribution and digital forms/checklists can cover permit-style sign-offs, but there is no dedicated named permit-to-work workflow advertised. | |
| Site inductions | Digital induction blocks check-in until acknowledged - readable in 9 worker languages. | Digital site inductions are a core feature, delivered in-app alongside RAMS and toolbox talks. |
| Multilingual inductions (9 languages) | Workers read and acknowledge key H&S details in 9 languages at the entrance QR; the language used is recorded in the audit trail and translations are site-team reviewable. | — |
| RAMS sign-off (per worker) | Per-worker RAMS acknowledgement can block check-in until the current version is signed; captured in the audit pack. | — |
| Worker cert tracking | CSCS upload, internal review and expiry notifications. | Skills and certifications (including CSCS-type competencies) are tracked per worker as part of workforce/subcontractor management. |
| Right to work | Records Home Office share-code checks with outcome, expiry and an evidence file (manual verification, not a live API). | Right-to-work verification is included in onboarding/subcontractor management. |
| Contractor self-onboarding | Contractor self-join via the entrance QR with CSCS upload and approval. | Strong subcontractor onboarding and management is core, though it is framed as employer-driven onboarding rather than a worker self-enrolment QR flow. |
| QR / mobile sign-in | Permanent entrance QR for guest sign-in/out and contractor self-join. | Sign-in/out is via the iOS/Android app with GPS capture; not positioned around a fixed entrance QR for guests/contractors. |
| GPS clock-in | GPS-verified clock-in is a headline feature — location captured at sign-in/out to confirm who is on site in real time. | |
| Biometric access | ||
| Physical access control | ||
| Site attendance | Check-in/out, history and a live people-on-site view. | Time & attendance is foundational; digital timesheets are auto-created at sign-in/out with real-time hours. |
| CIS payroll | Hours flow straight to payroll with CIS calculated automatically — a clear differentiator versus Site Control. | |
| Live people-on-site | Triggered evacuation + muster roll-call: snapshot who is on site, mark each person safe, export a roll-call PDF. | Real-time field management shows who is on site at any moment via GPS-verified clock-ins. |
| Multi-company isolation | Each contractor company sees only its own workforce — test-verified. | Built to manage in-house teams and subcontractors together from a contractor's account; no advertised test-verified per-contractor-company data isolation portal. |
| RFIs | Create, attach, comment, answer and close — unique in this category. | |
| Document-review evidence | Version-specific read/acknowledge audit chain. | Documents are distributed and acknowledged in-app, but there is no advertised version-specific read/acknowledge audit chain like Site Control's. |
| Handover sign-off | Per-plot, per-trade hand-over sign-off signed in person on one phone; certified PDF emailed to developer and contractor; per-plot progress board. Unique in this category. | |
| Toolbox talks | Toolbox talks are distributed and acknowledged in-app alongside RAMS. | |
| Site inspections | Inspections and checklists are part of the platform, with photo and location capture. | |
| Incident log | Digital forms/checklists and reporting can capture incidents, but a dedicated incident log is not separately named in public materials. | |
| Plant / asset management | Asset tracking is an advertised module — an area Site Control does not cover. | |
| Workforce scheduling | Real-time field/workforce management is central, though public materials emphasise time capture and management rather than dispatch/rostering. | |
| Multi-site dashboard & exports | Attendance CSV, monthly H&S CSV/PDF and project audit-log exports. | Centralised multi-site view with real-time management reporting and PDF/share/save exports. |
| Mobile app | Native iOS and Android app (Chime Construction Software) for clock-in, documents and checklists. | |
| Offline mode | Field app captures data on site; an explicit offline mode is not confirmed in public materials. | |
| Single sign-on (SSO) | SAML single sign-on with Okta or Microsoft Entra; can be required across your company email domain. | — |
| Public API | Read-only REST API with scoped account keys, rate limiting and an OpenAPI 3.1 spec (projects, documents, workers, certifications, attendance). | — |
| Outbound webhooks | Signed real-time webhooks — documents generated/signed, certificates expiring, workers checking in — with retries and a delivery log. | — |

Pick the option that matches how your team actually works.
Chime is the better fit: GPS clock-in straight into automatic CIS payroll and asset tracking is exactly its sweet spot. Site Control is honest here — it has no GPS geofence, no CIS payroll and no plant/asset module, so it is not the right tool for a payroll-led subcontractor.
Site Control wins: it generates UK RAMS/CPP/COSHH, gates inductions until acknowledged, runs RFIs and isolates each contractor company's data (test-verified). Chime is built around a single firm managing its own workforce, not multi-company isolation, and distributes rather than generates documents.
Site Control's no-hardware QR entrance, unlimited workers per site and published per-site pricing make it quick to budget and deploy. Chime is also hardware-free but quote-only, and its depth suits larger payroll-led teams; for a lighter UK-CDM-first pack, Site Control fits better.

Short, straight answers - the same questions real builders ask.
No. Chime distributes RAMS, toolbox talks and other documents you upload, sending them to individuals, groups, sites or trades, but it does not author the documents. Site Control generates UK CDM documents — RAMS, CPP, COSHH and method statements — from the core Site Book platform. So with Chime you still author compliance paperwork elsewhere; with Site Control the generation and the on-site sign-off live in one place.
Chime, clearly. Its headline strength is GPS-verified clock-in that creates digital timesheets and flows hours straight into payroll with CIS calculated automatically. Site Control is honest about this gap: it records check-in and check-out attendance and exports it, but it has no geofenced GPS clock-in and no timesheet-to-pay or CIS payroll engine. If automated CIS pay is your priority, Chime is the right tool, not Site Control.
Chime targets subcontractors and labour-heavy trades managing their own operatives across many jobs, with timesheets, CIS payroll and asset tracking front and centre. Site Control is built for the principal contractor running an individual site, controlling access, gating inductions, running RFIs and keeping each contractor company's data isolated. They sit at different ends of the same project, so the right choice depends on which role you play on site.
No. Chime focuses on workforce management — attendance, payroll, onboarding, skills and document distribution — and does not advertise a request-for-information workflow or a version-specific read-and-acknowledge audit chain. Site Control includes both: RFIs to create, attach, comment, answer and close, plus version-specific document-review acknowledgements that build an audit trail. If you need project Q&A and acknowledgement evidence inside the tool, that is a Site Control strength.
Chime's UK pricing is quote-only: the site offers an ROI calculator rather than published per-user figures, so you must talk to sales to budget. Site Control publishes transparent pricing — from £675 per active site per month plus a one-off setup fee, with volume tiers, and unlimited workers per site. If you want to model cost before a sales call, Site Control's per-site figure is easier to plan around than Chime's quote.
Yes. Both are deliberately hardware-free. Chime explicitly removes the burden of hardware procurement and runs through its iOS and Android app with GPS clock-in. Site Control uses a permanent entrance QR plus browser sign-in on the worker's phone, with no turnstiles, biometrics or gates. Neither requires access-control capex, so both deploy fast — the difference is what they do once people are on site, not the hardware to get them there.
