VAT Determination for Cross border transactions

VAT Determination for Cross border transactions

Cross-border chain transactions—often referred to as triangulation or A-B-C supply chain flows—are among the most complex challenges in indirect tax compliance. When Company A sells goods to Company B, who in turn sells them to Company C, but thephysical goods ship directly from A to C across EU borders, determining which leg of the transaction is tax-exempt and which is subject to local VAT requires precise logical evaluation.

Why Native SAP Struggles with Chain Transactions

Standard SAP ERP systems natively struggle with these scenarios. This is an overview of why native SAP falls short and how Meridian's VAT determination tools (such as the Meridian VAT Add-on and ARCO Determination) solve chain transaction complexities directly within SAP.

Standard SAP relies on static condition techniques (like access sequences looking at departure country, destination country, customer tax classification, and material tax classification). In a chain transaction:

1. Isolation of Sales Legs

Standard SAP evaluates the A-to-B sales order separately from the B-to-C sales order. It cannot easily ``look through`` the full
physical movement of goods versus the chain of financial invoices.

2. Transport Assignment Ambiguity

Under EU VAT rules, only one leg in a chain transaction can be the tax-exempt intra-Community supply (the ``transported
supply``). Deciding which leg gets this exemption depends on who arranges transport, where intermediate parties are registered, and transport documentation. Standard SAP cannot dynamically evaluate these combined variables out of the box.

3. Customization Nightmares

To handle drop shipments and triangulation natively, companies often end up moving away from the SAP standard condition record and instead creating their own complex condition record structures and then creating often thousands of condition records against these structure that need to be maintained, hardcoding user exits or forcing sales order desk teams to manually select VAT parameters—leading to high error rates and audit exposure.

How Meridian VAT Determination Solves SAP Chain Transactions

Meridian’s tax technology solutions—whether implemented as an on-premise VAT Addon directly inside SAP or via ARCO Determination on the SAP Business Technology Platform (BTP)—retrofits SAP with intelligent tax determination logic designed specifically for complex supply chains.

End-to-End Dynamic Evaluation

Meridian evaluates the entire chain flow holistically rather than treating each billing document in isolation. By analysing the physical dispatch location, final destination, ship-to party, customer VAT identification numbers, and transport arrangement logic simultaneously, the tool automatically identifies:
• Which sale constitutes the exempt intra-Community supply.
• Which sale is a domestic supply or falls under triangulation simplified rules.
• When the reverse charge mechanism applies.

Built Directly Inside SAP (No External Interfaces Needed)

Unlike third-party tax engines that require complex data replication and custom external interfaces, Meridian operates natively within SAP. It uses standard SAP master data directly, ensuring zero latency, no duplicated master data, and seamless integration with SAP SD (Sales and Distribution) and MM/AP (Materials Management / Accounts Payable).

Centralized Control via the VAT Cockpit

Tax and finance teams gain direct ownership over VAT determination logic without needing IT to write code or configure complex condition tables. Through the VAT Cockpit:
• Rules for drop shipments, triangulation, and ex-works deliveries can be configured or updated centrally.
• Live VIES VAT ID verification ensures intermediate parties hold valid VAT numbers prior to applying exemptions.
• Detailed decision tracking logs provide a transparent audit trail showing exactly why a specific tax determination was made for a given transaction.

Proactive Real-Time Control & Blocking

To safeguard against penalties during VAT audits, Meridian incorporates automated risk controls. If a required VAT ID is missing the system blocks non-compliant flows before the invoice is finalized.
