Invoicing with e-invoicing built in, gapless numbering and automatic tax-authority submission

Part of Finance

An invoicing platform built around Romanian tax obligations. Since January 2026, electronic invoicing is mandatory for B2B, B2C and B2G with a five-working-day deadline — StarBill makes that a step of issuing rather than a separate operation someone can forget.

Modules and capabilities

  • Invoice issuing

    Numbering guaranteed to be gapless, even when two requests arrive at once — a compliance requirement, not a technical detail.

  • Tax authority submission

    The invoice goes out in the required electronic format as part of issuing. Migrated history is never resubmitted by accident.

  • PDF documents

    The invoice rendered as a PDF with a stable appearance over time — an old document still looks the same years later.

  • Customers and products

    The data you reuse on every issue, with per-line VAT for mixed-regime cases.

  • Public invoice links

    Every invoice gets a link the customer can open without an account. Issued links stay valid permanently.

  • Notifications to other systems

    Other applications can be told when an invoice is issued or paid, through guaranteed delivery rather than calls that can be lost.

What sets it apart

  • E-invoicing as a flow, not an export

    Submission is part of issuing. There is no manual step to forget and no fine that follows from forgetting it.

  • Numbering that holds under concurrency

    Two invoices issued in the same second cannot produce a gap or a duplicate — the classic failure of invoicing under load.

Price on request

Pricing depends on user count and the modules you need, so I discuss it case by case.
