Eque2 Construct Mobile is a companion app for our Eque2 Construct job costing and estimating package that is sold to construction companies in the UK and Ireland. The app allows site deliveries to be booked in using a mobile phone or tablet. Once the details of a delivery have been entered, along with some optional notes and photos, the details are then sent via the web to the Construct database at the customers offices. This allows Construct users in the accounts department to automatically match up supplier invoices with the deliveries entered on-site via the mobile app.
