Why 4apps

From ERP to digital compliance

ViDA, e-invoicing and digital reporting are reshaping how organisations structure their financial and tax processes. Compliance is moving to the heart of the ERP landscape. Transactions, invoices, VAT data and reports must be reliable, auditable and increasingly available digitally and in near real time.

Meeting these demands takes more than a standalone compliance solution. It takes a partner who understands ERP, finance, indirect tax and compliance. That is where 4apps makes the difference.

The strength of 4apps: one integrated, end-to-end approach.

  • E-invoicing mandates are live or announced across the EU, each on its own timeline.
  • ViDA brings EU-wide digital reporting for cross-border trade from 1 July 2030.
  • Prefilled VAT returns shift the burden of proof to you.
One partner. From transaction to compliance.

Reconciled, traced and auditable.

4apps brings Oracle, finance, indirect tax and compliance together in one integrated approach. Every transaction is reconciled with Oracle first. Only then do we file the VAT return, send the e-invoice or report to the tax authority. And every filed figure stays traceable to the Oracle transaction behind it.

Our foundation

Built on operational intelligence. Designed for ViDA compliance.

We take transactional data from Oracle in near real time: the actual operational data behind every invoice and journal, not a monthly BI extract. From that one reconciled data set we build your VAT return, your audit file, your e-reports and your e-invoices. So your data, reports and filings stay in sync, traceable and auditable.

Audit files that match your return

Tax authorities use audit files such as SAF-T to check your VAT returns. e-Audit creates them from the same reconciled data as the return, so the two match by design. Available in 9 countries, including SAF-T, GoBD (Germany), FEC (France) and FAIA (Luxembourg).

Reconciliation first

Tax authorities already know your numbers. Can you prove yours?

itax4apps shows in one screen that EUR 100 million in reported revenue is made up of these invoices, with this status, in this SAF-T file, adding up to exactly EUR 100 million (illustrative figure). So when a prefilled VAT return arrives, your team can confirm it or challenge it the same day.

Ready for ViDA

One Oracle. Every mandate on its own timeline.

ViDA lets EU member states introduce domestic e-invoicing, and brings digital reporting for intra-EU trade from 1 July 2030. Meanwhile national mandates are going live country by country. 4apps tracks them for Oracle customers, so your roadmap follows the law, not the other way around.

Frequently asked questions

What does 4apps do?

4apps connects Oracle Fusion Cloud ERP and Oracle EBS to VAT, e-invoicing and digital reporting obligations in Europe and beyond. We combine 25 years of Oracle expertise with indirect tax knowledge, and deliver this through itax4apps (compliance platform), etax4apps (Oracle Tax Engine configuration) and our Oracle practice.

What is itax4apps?

itax4apps is one compliance platform for Oracle. It covers VAT returns, EC Sales Lists, audit files such as SAF-T, e-reporting to tax authorities and B2B e-invoicing, all reconciled with the source data in Oracle before anything is sent.

Do I need a separate e-invoicing provider?

No. e-Invoicing is part of itax4apps. VAT filing, audit files, e-reporting of invoice and B2G data to tax authorities, and outbound and inbound B2B e-invoices all run on the same reconciled Oracle data, in one application. That is also why we do not offer e-invoicing on its own: we reconcile first, then send.

Can itax4apps create SAF-T and other audit files?

Yes. e-Audit creates statutory audit files such as SAF-T, GoBD, FEC and FAIA in 9 countries, from the same reconciled Oracle data as your VAT return.

What about cross-border invoices?

Under ViDA, intra-EU B2B invoices must be e-invoiced and digitally reported from 1 July 2030. This is on the itax4apps roadmap, on the same reconciled flow.

Is itax4apps a tax engine?

No. Tax is determined by the Oracle Tax Engine inside your ERP. 4apps configures that engine through etax4apps. itax4apps reports, reconciles and exchanges what Oracle has posted.

How does itax4apps help with ViDA?

ViDA and national mandates require invoice level data that matches your VAT return. itax4apps reconciles each e-invoice and report with the Oracle transaction behind it, so you can prove your figures, also against a prefilled VAT return.

Does itax4apps change data in Oracle?

No. Oracle remains the single source of truth. Corrections are made in Oracle and show up in itax4apps within minutes.

Which countries does itax4apps cover?

29 countries: 24 EU member states plus the United Kingdom, Norway, Switzerland, Türkiye and the United Arab Emirates. See the countries page for modules and upcoming mandates per country.

How long does implementation take?

Typically two to three months for the first country. Additional countries are often faster, because the foundation is already in place.

Does 4apps guarantee compliance?

No. itax4apps supports your compliance process. You remain responsible for your data, your Oracle configuration, your tax treatment and your filings.
