Zyntra OS by Double Support

Contracting software for contractors in the UK

Zyntra Contracting runs a contractor’s projects from the bill of quantities to the last progress bill: what was measured, what was billed, what each subcontractor is owed and what is retained. For a company in the United Kingdom, Zyntra OS keeps the books in pounds sterling with VAT on each line, and reads UK banks through GoCardless.

Zyntra Contracting, the contracts: owner, project, period, value, certified and invoiced, and progress

A day for a contractor

The site engineer measures what was built this month. The office turns the measure into a progress bill against the bill of quantities, a subcontractor sends its own bill for its share of a line, and part of each bill is held back as retention until the work is handed over. In Zyntra Contracting a measured quantity can never go below the previous bill or above the bill of quantities, so nothing is billed twice and nothing beyond the contract.
