Log every piece of PPE, track its inspection dates, and get reminded before a LOLER thorough examination is due. The bit a generic invoice app will never do.
Harnesses, lanyards, descenders and connectors, each with make, serial number and purchase date.
See "due in 6 days" before it's late. Pre-use, interim and 6-monthly thorough examinations, all dated.
Attach the inspection certificate photo or PDF to each item, ready to show on site.
On a rope access site, out-of-date kit means you're off the job. Cowstail keeps the whole register and its dates in your pocket, so a thorough examination never sneaks up on you, and you've got the paperwork the moment anyone asks.
