Mail + invoicing

Your company's email.Your company's invoices.

Mailboxes on your own domain that work in Outlook and on a phone, and invoicing that holds up in front of an accountant. Priced per person and per mailbox — separately, because those are different needs.

No card. Nothing is deleted if you stop.

Press a template. The invoice changes.

Not a screenshot — the same switch the product uses. Pick a colour too; the text over it flips between white and black by contrast, automatically.

Two products

Two products that belong together.

Mail

IMAP, JMAP, SMTP, CalDAV and CardDAV on your domain. Autodiscover published, so your people type an address and a password.

  • Aliases, groups, forwards — free and unlimited
  • Reverse charge — VIES-checked, with the date kept
  • DKIM keys held by us — servers move without touching your DNS
  • Migration over IMAP — resumable, non-duplicating
  • Spam refused at the door, not accepted then bounced
  • Per-mailbox send limits from day one

How mail works

Invoicing

Quotes, invoices, credit notes, proformas, recurring templates, payments and expenses — with the rules of the trade enforced, not suggested.

  • Gap-free numbering, issued documents immutable
  • VAT from the base, as EN 16931 requires
  • EN 16931 / Peppol plus 17 national providers
  • Aging, VAT and profit reports, CSV for the accountant
  • Five templates, 8 languages, any currency

Straight talk

What we do not do.

Said here rather than discovered in month three.

  1. We are not your accountant

    Thresholds, cash-basis schemes and filings stay with them. We give correct figures and a clean export.

  2. We do not sign with your tax certificate

    In Brazil and Mexico it stays with you or with the provider. Nobody else can legally hold it.

  3. We do not file periodic returns

    SPED, DIOT, GSTR and JPK are not submitted from here.

  4. We are not a legal archive

    We keep your PDFs and XMLs. The statutory retention obligation is yours.

  5. No bookkeeping, payroll or stock

    Those are different products, and a suite claiming all of them does none of them well.

Fourteen days. No card. Nothing deleted if you stop.
