How do you hand over accounting from weclapp to BMD as a SaaS provider in Austria?

weclapp offers a BMD export for Austrian customers. It runs on a journal basis: you choose the period, start the export and find the file in the log for download for your tax advisor. It is set up under Global settings > Accounting > Export > BMD export settings.

As the standard chart of accounts for Austria, weclapp provides the Einheitskontenrahmen Austria, which you import via the accounting wizard. On request, your accounting firm can get free access to your system (according to the weclapp price page, as of October 2026; the single license “weclapp tax advisor” can only be booked together with ERP Services or ERP Trade).

The menu paths come from the weclapp help (as of November 2023); click through them to verify.

A fictional example: a Viennese app business with 800 subscriptions bills mostly monthly, so around 800 invoices per month, and works with a BMD accounting firm.

In the first way, weclapp creates the recurring invoices itself. This requires the Contract Management add-on, weclapp list price, as of October 2026, €55 per person per month.

In the second way, your billing system creates the invoices via REST API. The API is available from ERP Services, not in the Starter: €86 for annual or €95 for monthly billed licenses per user per month, net (weclapp list price, as of October 2026).

Calculation scheme for the first way: package price × number of users, plus the add-on for the people who work with it. With one person, you get €86 + €55 = €141 for annual or €95 + €55 = €150 for a monthly billed license, net per month. For API-only operation, one ERP Services license is enough; there is no minimum number.

There is no native weclapp standard for splitting a bulk payout into individual payments and fees; wals.pro uses Zahlungsabgleich 4 weclapp for this. More on the page Matching subscription payments to invoices. How AI can help with setup and where its limits lie is described on the page AI setup for weclapp.

Deadline and obligation. If you bill domestic businesses, you issue the invoice within six months after the transaction is performed; for private individuals you are generally entitled to do so, not obliged (§ 11 para. 1 no. 1 UStG 1994, RIS, retrieved 11.10.2026). For other services to businesses in other EU states where the recipient owes the tax, a shorter deadline applies: no later than the 15th day of the calendar month following the month of the service (no. 2). The recipient's VAT ID number and a note on their liability for the tax must then appear on the invoice (para. 1a). Which case applies, you clarify with your accounting firm. What a weclapp license with API delivers is on the page Accounting for SaaS, apps and subscription business.

Subscriptions. The invoice states the day or the period over which the service extends, so for an annual subscription the annual period (para. 1 no. 3 lit. d). For billing by sections, the billing period of up to one calendar month suffices; whether your subscription service falls under this, you clarify with the accounting firm. If you receive payment for a service not yet performed, for example for an annual subscription in advance, the invoicing rules apply accordingly (no. 4). The VAT then arises at the end of the advance return period in which you receive the payment (§ 19 para. 2 no. 1 UStG 1994); only the revenues are spread over the months by the accounting firm for bookkeeping purposes.

You retain invoices for seven years (§ 11 para. 2 UStG 1994, § 132 BAO, both RIS, retrieved 11.10.2026). The period runs from the end of the calendar year to which the document relates, and longer while a tax proceeding is pending. Retention on data carriers is permitted if complete, orderly, content-identical and original-faithful reproduction is ensured; for records that exist only on data carriers, original fidelity is not required (§ 132 para. 2 BAO), and for e-invoices, according to USP, likewise.

An electronic invoice (including a PDF by email) is valid with the recipient's consent if authenticity of origin, integrity of content and legibility are ensured. If you issue the same invoice in several formats, note this on the invoice. Toward the federal government, contractual partners have been required to use structured e-invoicing since 01.01.2014, transmitted via the Unternehmensserviceportal or PEPPOL (USP, as of 01.01.2026, retrieved 11.10.2026). Which formats weclapp outputs for this is not described in the weclapp documentation. Mandatory details, formats and the small-amount rule are on the page E-invoicing in Austria, for German business customers on E-invoicing for subscription providers.

VAT advance return. The weclapp documentation describes only submission via ELSTER, and for the default country Germany (page changed 17.10.2025); FinanzOnline does not appear. An advance return from weclapp to the Austrian tax office is therefore not documented. It is due no later than the 15th of the second following month; with up to €100,000 in revenue in the previous year, the calendar quarter applies (quarter 1 by 15 May), on request the calendar month; with low revenue, the advance return may be omitted, which you clarify with your accounting firm (§ 21 UStG 1994, RIS, retrieved 11.10.2026).

Cash-basis taxation (Ist-Versteuerung). On the ELSTER advance return, the weclapp documentation states: “No, weclapp currently only supports accrual-basis taxation (Soll-Versteuerung).” In Austria, you must calculate the tax on payments received (Istbesteuerung) if you are not required to keep books for your commercial revenues (typical: sole proprietorships with cash-basis accounting), as well as a freelancer. Corporations are generally required to keep books and pay tax on agreed consideration (Sollbesteuerung). On application, the tax office permits Sollbesteuerung (§ 17 para. 1 and 2 UStG 1994, RIS, retrieved 11.10.2026). What this means for your bookings and the BMD export, you clarify with your accounting firm before the start.

Recapitulative statement (Zusammenfassende Meldung). For services to businesses in other EU states with tax liability on the recipient, a recapitulative statement is required, in principle via FinanzOnline (USP, as of 01.01.2026, retrieved 11.10.2026). weclapp offers a report for this, which weclapp support enables on request; the documentation (page changed 13.11.2023) describes it for German conditions. Whether it is enough for the filing via FinanzOnline, you check with your accounting firm.
