AVY Systems

Invoice & Bookings

Built for corporate AV crew — techs, engineers and freelancers working shows. It does the one thing the other apps get wrong: a whole run of days, one client, one invoice.

What it does

iPhone and desktop. Works offline.

Multi-day runs — a week of shows bills as one invoice, each day priced on its own
Overtime that matches your rules — thresholds, multipliers, night premium, day minimum
Bookings calendar that warns you before you double-book
Proper PDF invoices you can send from your phone
Saved clients, rate buttons, invoice log, CSV export
Private tax set-aside — never shown to the client
Your data stays on your device — no account, no cloud

Know someone who works shows?

Most people find this from another tech on a gig. Send it to someone who is still billing a five-day run five times.

Install it like a real app

iPhone: open it in Safari, tap Share, then Add to Home Screen. Mac: open in Safari, then File → Add to Dock. It runs full screen with its own icon. After the first time you open it, it keeps working with no signal — on a job site, in a basement, on a plane.

Your data never leaves your device. There is no account and no server copy — which also means we cannot recover it for you. The app has a Save a backup button; use it now and then, and always before you switch phones. That backup file is also how you move your data between your phone and your desktop.
