QUESTIONS, ANSWERED

Thoughtful about what comes next.
Tickzu is being built for independent UK gas and heating engineers who manage the visit, the customer relationship and the paperwork themselves.
The application is in development. Access and launch details will be confirmed before sign-up opens.
No. Tickzu records a service per appliance, with checks, readings, signatures and a branded PDF. That service record is not a Gas Safety Record (CP12) and makes no compliance claim; the engineer remains responsible for the checks they carry out and sign. Tickzu is not endorsed by Gas Safe Register.
Tickzu connects to FreeAgent (in the development app, FreeAgent’s test system) and sends your contacts and invoices across; records already linked are recognised when you send again. Xero is planned. You can also build an Accountant Pack with CSV files, a summary and receipt images for any period. Neither is a tax return.
There is a Free Forever plan with monthly limits (for example 35 customers and 20 new jobs a month), and Pro, with no limits, at a founding price of £9.99 a month or £99 a year, after a 14-day free trial. Founders keep that price for as long as they stay subscribed. Founders never pay more than a new subscriber. No payment is taken on this website.
You can encrypt your records on the phone, lock the app with Face ID or your passcode, and keep a password-protected backup file. If you sync two phones, records are encrypted before they leave the phone, so the server holds only data it cannot read. Keep your backup password safe: nobody, including Tickzu, can recover it.
