About Constrigo
Construction resources: inform, calculate, learn
Finding reliable information about running a construction business often takes longer than the job itself. This construction resources hub brings together, in one place, the content that matters day to day for a tradesperson or the owner of a small or mid-sized firm: a blog that breaks down regulation and industry news, practical guides that walk through sensitive tasks step by step, free calculators to work out a figure without a spreadsheet, and a help center to move forward on your own. The blog covers concrete topics: the VAT rate that applies to a given type of work, retention guarantees, 2026 e-invoicing, job-site management and answering public tenders. The practical guides turn each topic into a procedure: building a compliant quote, tracking progress billing, organizing your administrative documents. The calculators handle the recurring math — margin, labor hourly cost, VAT, retention guarantee — so you can decide fast, on site as well as at the office. The goal stays simple: less time spent searching, more time on the job site. Every resource links to the others, from blog to guide and from guide to calculator, so you find a complete answer without juggling tabs or repeating the same searches. From a first quote to a closed retention guarantee, the relevant guide, calculator and article are always a click away.
