Version 1.2.1 fixes billing bugs and tidies up invoices. • Fixed: editing a billing could save the same package or product twice, doubling its line. Lines that were already duplicated are merged automatically, and the price and pass count now match what was credited. • The billing screen now reloads the latest billing each time it opens, so edits always start from up-to-date lines. • Invoices and receipts now print on A4 with a more compact layout. The billing policy appears above the diary policy.

Billing just got smarter. • Pick the billing date and see each student's study period at a glance, on the card and on the invoice. • Refund a billing or reopen a session in one tap. Passes are restored automatically. • Fresh Classic and Modern templates make your invoices and reports look professional, in your brand color. • Dates now read naturally in your language.

What's New in 1.1.0 • Refund a purchase: undo a pass purchase from the billing list. The passes are taken back, the balance updates, and the billing returns to open so you can redo it. • Reopen a completed session: marked a session complete by mistake? Reopen it and the passes charged for it are returned automatically. • Smoother lists and sheets when adding students and classes. • Under-the-hood improvements for speed and stability.
