You can now issue immutable payment receipts for order and group payments, with beautifully branded PDF documents in both English and Icelandic. Each receipt captures a frozen snapshot of the payment at issuance time — if you need to edit a payment that already has a receipt, the system automatically voids the old one and issues a corrected replacement, ensuring your records stay accurate and trustworthy.

The invoice system received significant enhancements too. Invoices can now be voided when issued in error while preserving their fiscal number for your records. Client identities are frozen at invoice issuance, so documents remain properly bound even if you reassign the order's client later. The invoice PDFs themselves sport a fresh new design that matches the receipt style — a clean header, clear identity blocks, and a professional layout that looks great whether you're sending to clients or filing for your records.

Document delivery just got more powerful with multi-recipient support. When sending order documents, you can now select multiple recipients from the client and all participants, choose which invoices and receipts to attach, and customize the email body — all in a redesigned three-column dialog that shows your settings, email editor, and live preview side by side. For group organizers, we've added comprehensive cost tracking and invoice generation. Track your operational costs, generate sponsor invoices with full VAT breakdowns, and view coverage ledgers to see exactly how payments are distributed across your group bookings.

We've also streamlined email creation with reusable content blocks. Write common information once, then reference it across multiple email templates — the content automatically updates everywhere when you make changes. Plus, all your reports now support saved views with chip-based filters, making it easier to return to your preferred configurations. Also improved: payment receipts can be delivered manually from the action menu, the sales overview preview now handles 500 rows with client-side sorting, capacity type reminders appear when enabling availability control, and the orders list expands inline to preview participants and bookings.
