Built by people who build
The connected back office for UK contractors and subcontractors: sales, technical, site, commercial, accounts and aftercare, from first enquiry to the end of the defects period, all in one place. Behind it sits the UK Construction Directory, built on live Companies House data, so you can find and check the firms you work with.

Why we built it
Our founders have more than 35 years in UK residential development and construction. Construct365 works alongside the tools a firm already uses and keeps one connected record from first quote to handover. Your accounts stay in your own accounting software (Xero today); Construct365 keeps bills, invoices, CIS and paid status in step with it.
