This is a big one for anyone sending invoices across borders in Europe. Sliptree now speaks Peppol, supports e-invoicing in Latvia and Lithuania, and the whole setup flow has been rebuilt to be much easier to get through.
Until now, e-invoicing in Sliptree was Estonia-only — both ends of the invoice had to be on the Estonian network. That's no longer the case. Sliptree now sends Peppol BIS 3.0 compliant UBL invoices, which means an Estonian company can send an e-invoice to a customer in Latvia, Lithuania, Finland, or any other country on the Peppol network. The UI shows which network each invoice was delivered through (Estonian or Peppol), so you always know how it went out.
Latvian and Lithuanian companies can now send e-invoices directly from Sliptree, with the same fluency Estonian users have had. This includes country-specific prerequisites — for example, Latvia requires a VAT ID — and a representation rights check against the Latvian VISS registry, so we know the person setting it up actually has authority to do so on behalf of the company.
We've significantly streamlined the e-invoicing setup. It's now a step-by-step guided flow that walks you through identity verification, representation rights, prerequisites, and activation — only showing what's relevant for your company's country. If something's missing, you'll see exactly what and why. If automated checks aren't available in your country, you can self-attest to your representation rights and continue.
When delivery status data is available, e-invoice delivery and bounce events now show up in the invoice activity log — so you can see at a glance whether an e-invoice actually reached the recipient.
