The Construction OS

Run the entire buildfrom one system.

Tender to handover, site to boardroom. NESTO holds every project, contract, purchase order, inspection, invoice and person a construction company runs on — in a single workspace, under a single set of permissions.

One workspace per company. Accounts are provisioned by your administrator.

Nothing is re-keyed from one team to the next.

01The problem

Most construction companies run on eleven systems that never speak.

Not one of them is wrong on its own. Together they are a reconciliation job that runs every month, forever, and quietly costs more than the software.

  • A tender spreadsheet, a site group chat and the accountant's folder.

    One project record every department reads from and writes to.

  • Monthly reporting assembled by hand from four exports.

    A dashboard that is already the report, for the role reading it.

  • Access decided by who happens to have the file.

    Access decided by role, and refused on every single request.

  • A general business tool bent into the shape of construction.

    Procurement, QA/QC and HSE as first-class modules, not add-ons.

02The platform

Seventeen modules. One workspace.

Every department in the same system, on the same project record — with procurement, quality and safety treated as first-class work rather than add-ons.

Work

The day-to-day of delivering a project.

10

Projects

Every project as one record: programme, team, budget, drawings and status.

Tasks

Daily work assigned across site and office, always against a project.

Meetings

Agendas, minutes, decisions and the actions that follow — each action able to become a task.

Timesheets

Weekly timesheets against projects and tasks — logged in minutes, approved by the right person, reported without surveillance.

Daily Logs

One site diary per project per day — workforce, work done, deliveries, delays and photos, reviewed and locked as the record.

Workforce

Every worker the company employs, with or without a login — trades, crews, project sites and the attendance recorded where they work.

Contractors

Every contractor you engage — project assignments, work packages, insurance and guarantees, and the contracts behind them.

Engineering

Drawing and document registers with controlled revisions, RFIs, submittals, method statements and transmittals.

Clients

Clients, contacts, and the history of every job you have delivered for them.

Documents

Drawings, method statements, certificates and contracts in one place.

Departments

The eight functions a construction company runs on.

08

Finance

Budgets, invoices, payments and cost against value — per project and company-wide.

HR

Crews and staff, attendance, leave, records and recruitment.

Sales

Pipeline, opportunities and proposals — the tender before it becomes a contract.

Legal

Contracts, approvals and notices, with the paper trail intact.

Procurement

Requests, RFQs, tenders, suppliers, purchase orders and deliveries.

Inventory

Materials, stock levels and movements across stores and sites.

QA/QC

Inspections, non-conformances, tests and punch lists, closed out on the record.

HSE

Incidents, permits, inspections and corrective actions.

Company

The organisation behind the projects.

06

People

Everyone in the group, with where they work, what they work on and how to reach them.

Team

Everyone in the company, with the department and role they work under.

Organization

The parent group above your companies: its departments, the heads who run them, and the people HR brings in.

Company

Company identity and the details every document is issued under.

Settings

Roles, users, module activation and appearance, held by the administrator.

Support

Internal requests and the knowledge base your own team writes.

03Built around the role

Sixteen people open NESTO and see sixteen different companies.

A site engineer should not have to walk past the payroll to reach an inspection. In NESTO, the role decides the navigation, the dashboard, the quick actions and what the server will answer — all from one configuration.

04End to end

From the tender that wins it to the account that closes it.

A project does not stop at handover and it does not start on site. NESTO follows the whole thing, and every stage writes to the same record.

05Why it feels different

Premium is not decoration. It is what has been left out.

A narrow palette, one type scale, one component library and no ornament that does not carry information.

Fast, on purpose

Pages render on the server and ship almost no JavaScript. This site loads no images at all — every line, chart and frame you see is drawn from the same tokens the product uses.

  • Server-rendered
  • No image payload
  • Instant navigation

One system, visibly

Seventeen modules, one design system. A single file holds every colour, radius, shadow and duration, so no screen invents its own. Learn one module and you have learned all of them.

  • One token set
  • One component library
  • One layout standard

Control by construction

Permissions are derived from the role, not written into screens. A module hidden from the sidebar is also refused by the router — the two are the same configuration, so they cannot drift apart.

  • Role-derived access
  • Refused at the edge
  • Refused again in the page

06Access

Access is a structural decision, not a setting.

Construction data is commercially sensitive long before it is legally sensitive — margins, claims, incidents, payroll. NESTO treats access as part of the architecture rather than a checkbox on an admin screen.

Role-derived permissions
Permissions are generated from each role's navigation. Granting a module in the sidebar grants the view permission; removing it removes the grant. Feature code asks whether a permission is held, never which role is signed in.
Enforced twice
Every request is checked at the edge by middleware, then again inside the page it reached. A route added without a middleware rule fails closed rather than open.
Read-only means read-only
Roles marked read-only have every non-view grant stripped when permissions are built, whatever a table says. A Viewer cannot reach a create route by typing the URL.

07Questions

The six things everyone asks first.

What exactly is NESTO?

A construction ERP: one workspace holding projects, tasks, clients, documents, finance, HR, sales, contracts, procurement, inventory, QA/QC, HSE and company administration. Not a project tool bolted to an accounting package — one system with one database behind all of it.

Which modules are included?

All seventeen, on every plan. There is no edition that withholds a module until you upgrade, because a company that cannot afford the quality module is exactly the company that needs it.

Does it work on site?

The whole application is responsive down to a phone. Below tablet width the navigation moves into a drawer and the layout narrows to a single column — the same screens, not a reduced mobile version.

How do people get accounts?

Your administrator provisions them inside your company workspace and assigns the role. There is no public sign-up: a construction company's workspace is not something anyone should be able to join.

How is access enforced?

Twice. Middleware checks the session and the role configuration at the edge before a page is reached, and the page checks the permission again itself. A route added without a middleware rule fails closed.

How is NESTO priced?

Per company, per month, with every module included and a user ceiling per plan. Pricing is on the pricing page — no quote required to see a number.
