Construction and renovation

In construction, information is created on the job site and too often ends up on paper, then retyped at the office. We build simple tools for field crews and connect them to your payroll, accounting and estimating software.

Let’s talk about your project

What we often hear

  • Paper timesheets retyped every week for payroll
  • Quotes built in Excel files that differ from one estimator to the next
  • Job site photos and notes scattered across phones
  • No clear view of a project’s profitability until it is over

Project examples

● Illustrative scenario

Field app for timesheets and work orders

Starting point

A 25-employee contractor receives hours on paper every Friday. Someone at the office spends a day each week retyping them into the payroll software, with errors to fix afterwards.

What gets built

  • Offline mobile app: hours per project, photos, client signature
  • One-click approval by the foreman
  • Automatic export to the payroll software
  • Hours-per-project dashboard for cost tracking

Target: eliminate the weekly retyping and know the actual hours on each project day by day.

Technologies: React Native / Expo, Node.js, PostgreSQL, AzureTypical duration: 8 to 12 weeksServices: Web and mobile apps, Integrations and APIs

● Illustrative scenario

Standardized quoting tool

Starting point

Each estimator uses their own Excel file. Material prices are out of date and quotes do not look the same.

What gets built

  • Central catalogue of products, rates and margins
  • Quotes built from templates by type of work
  • Branded PDF sent to the client from the tool
  • History of accepted and declined quotes

Target: faster quotes that are consistent across estimators, with a measurable win rate.

Technologies: Next.js, TypeScript, PostgreSQLTypical duration: 6 to 10 weeksServices: Custom software

These scenarios describe typical projects for this industry. They are not client engagements: they show what a project can fix and how long to expect.

Frequently asked questions

Does the app work without a network on the job site?

Yes. We design field apps to work offline: data is stored on the phone and synced as soon as the network is back.

Can it connect to our payroll or accounting software?

In most cases, yes, through an API or file exports. We confirm the method with you before starting.
