What is new in 10.4.0.0

The e-invoicing release: send a real e-invoice, chase every overdue bill in one click.

Version 10.4 brings MyCompany into the era of structured e-invoicing: alongside the PDF, it now exports a proper UBL / Peppol e-invoice your accountant or portal can read directly. Chasing late payers is one click for the whole list. And the workspace toolbar was rebuilt — calmer, tighter, and steady on a 1080p screen.

Timely

UBL / Peppol e-invoicing

Select a sales invoice and choose Export e-invoice to write a standards-compliant UBL 2.1 / Peppol BIS 3.0 XML next to your PDF — supplier and customer details, per-rate VAT, IBAN, and every line. Hand it to your accountant, upload it to a portal, or feed it to an access point.

Get paid

Remind all overdue — in one click

One button writes the next reminder for every overdue invoice, escalating each from the level it already reached: first reminder, second, then final notice. Paid and not-yet-due invoices are skipped. You get one summary and the folder opens once — no dialog per invoice.

Calmer

A toolbar that stays put

Every workspace toolbar is now a single compact row that holds its shape at 1080p, even at 150% scaling. Rare filters moved into a Filters popup that flags itself when active, so the everyday view stays quiet.

Consistent

One search box, everywhere

Invoices, clients, and articles used to each have their own subtly different search field. Now they share one — same size, same placeholder, and a clear button (or just press Esc) instead of select-all-delete.

Foundation

Reminders, properly separated

The reminder logic moved out of the screen and into a tested workflow of its own — which is exactly what made one-click batch reminders a small change instead of a risky one. The screen it came from shrank by a fifth.

Trust

Still guarded, still green

The architecture checks that keep invoices correct and upgrades safe now cover the e-invoice builder too. Zero warnings, 777 tests green, on .NET 10.
