Does Dekimu issue compliant e-invoices for these countries?

No. Dekimu (and InvoiceUp) are follow-up and payment-tracking tools — they consume structured invoices, they do not issue them. Use your national e-invoicing platform or an accredited provider to issue; use Dekimu to chase what's unpaid.

When does the e-invoicing mandate apply to my business?

It depends on your country of establishment and your size band — most mandates phase in from large enterprises to SMEs over 1–2 years. Check the row for your country above and verify against the linked authority; announced dates move.

Is one mandate the same as another across the EU?

No. Each country runs its own platform and timetable — Italy's SdI, Romania's RO e-Factura, Poland's KSeF, Belgium's Peppol model, France's approved-platform model and others differ in format, clearance, and scope. Treat every country as its own rulebook and confirm against its authority.

What should I do now if a mandate is only announced for my country?

Track the announced dates, make sure you can receive structured e-invoices from your suppliers, and pick an accredited issuing route before the deadline. Keep chasing unpaid invoices as usual — the mandate changes how invoices are transmitted, not whether customers pay on time.
