About

Cowstail

Features
Read full description

Cowstail is the admin side of rope access, sorted from your phone. Built for IRATA and SPRAT technicians who would rather be on the ropes than on the paperwork. Find work, get paid, stay compliant. FIND WORK THAT FITS YOUR TICKETS Companies post rope access jobs; you see the ones matching your level and tickets. Apply with a snapshot you control, get offers, and accepted jobs land straight in your schedule with calendar sync. No open directory: your data is only shared when you decide. INVOICES THAT GET YOU PAID Create a professional invoice in under a minute. Automatic numbering, VAT and CIS handled, payment details on the document, and a public link your client can open without installing anything. See when it was viewed, log payments, chase overdues. KIT & LOLER, NEVER OUT OF DATE Your rig lives in the app: every descender, harness and rope with serial numbers and inspection dates. Cowstail tracks your 6-month LOLER thorough examinations and reminds you before anything lapses. QUALS IN A VERIFIABLE WALLET IRATA and SPRAT cards, first aid, offshore tickets: scan them once and carry them all. Share a revocable link so a company can verify your quals without endless photo requests. Expiry reminders included. TAX WITHOUT THE SHOEBOX Log expenses as they happen (scan the receipt, we read it). Income and outgoings organised by UK tax year, so self-assessment stops being an archaeology project. CAREER & LOGBOOK Your hours, your jobs, your progression towards the next level, all in one record. BUILT FOR COMPANIES TOO Post jobs, manage applicants, build your tech roster, plan projects and book crew with conflict checking. Auto-drafted invoices when a job wraps. Share any job as a link straight into your WhatsApp groups and socials: it opens as a proper job page, and applications land back in the app. PRIVATE BY DESIGN UK GDPR. Data hosted in the EU, encrypted in transit and at rest, daily tested backups. No ads, no data selling, ever. Read more at cowstail.app/security.html Free for solo technicians. No card required.
