Everything a self-employed rope access tech needs to get paid, stay compliant and be ready for the taxman. Nothing you don't.
Build a tidy invoice in under a minute, send it as a PDF or link, and watch its status: sent, viewed, paid, overdue. You'll know the moment it's opened.
Log every harness, lanyard and descender with serial numbers and dates. Cowstail reminds you before a LOLER thorough examination is due and keeps your certificates in one place. Learn more →
Income and expenses tracked all year, with a simple dashboard and one-click CSV export. When Self Assessment lands, the numbers are already done.

Mark each line as labour or materials and Cowstail applies the CIS deduction and VAT for you, per invoice or as a client default. The maths is always right, and the deduction shows clearly on the invoice.
Log hours against real jobs and watch your experience build month by month. Your IRATA level, revalidation countdown and logbook live together, always up to date and ready to export.


Pick your disciplines, rope techniques, sectors and roles from a shared library: NDT, blade repair, rescue, offshore wind and more. Your profile tells the full story, not just the certificates.
Scan your IRATA card and the qualification fills itself in. Scan a receipt and it becomes an expense. Scan a business card and it becomes a client. You check it, save, done.


Keep IRATA, first aid and CSCS together in a wallet and share a live link with any supervisor or client, expiry dates and certificates included. Set it to expire, revoke it any time.
Send a simple estimate, let the client accept it online, then turn it into an invoice in a tap.
Track your IRATA level, cards and first-aid expiry, and get reminded before they lapse.
Every invoice, quote and payment against the right client, with payment terms remembered.
Save your day rates and services once, then drop them into invoices and quotes in a tap.
Add your logo and colour so invoices, quotes and shared pages look like your business.
Record part-payments, spot overdue invoices at a glance and send a reminder in one tap.
