Scaling Cross-Border E-commerce into Denmark Without VAT Headaches

An online fashion retailer based in Southern Europe experienced rapid growth in orders from Danish consumers. The company operated a centralised warehouse in another EU country and shipped directly to private customers across the EU. As Danish sales increased, the finance team became concerned about distance selling thresholds, OSS rules and local VAT obligations. To avoid misinterpretation of evolving regulations, the management decided that Danish VAT should be handled through fiscal VAT representation in Denmark, with Radner's team coordinating the process.

The first step involved a comprehensive review of the retailer’s sales flows, platforms and payment methods. Orders were processed through multiple channels, including the company’s own website and several marketplaces. Each channel had different invoicing rules and commission structures, which affected the VAT treatment. Radner's team requested detailed transaction data, marketplace agreements and shipping terms. The objective was to determine when the retailer acted as the supplier of record and when a marketplace might be deemed the supplier for VAT purposes.

Radner's team then analysed historical sales volumes to Danish customers, comparing them against relevant thresholds and OSS declarations. The review revealed that Danish sales had surpassed key thresholds earlier than the client had anticipated. While some transactions were already reported through OSS, others required local Danish VAT registration due to specific marketplace arrangements. To regularise the situation, Radner's team proposed a dual-track approach: maintain OSS where appropriate and obtain Danish VAT registration under fiscal representation for the remaining flows.

Once the strategy was agreed, Radner's team initiated the Danish VAT registration process. The team compiled corporate documents, proof of e-commerce activity and explanations of the retailer’s business model. Particular attention was given to how returns, chargebacks and promotional vouchers were handled, as these elements can complicate VAT reporting. Communication with the Danish tax authorities was managed centrally, ensuring that the unique aspects of the e-commerce model were clearly explained. The authorities granted a VAT number, recognising the need for local reporting alongside OSS.

With registration in place, the focus shifted to building a scalable reporting framework. Radner's team designed a data extraction model that could handle high transaction volumes while preserving accuracy. The model distinguished between sales subject to Danish VAT via local registration and those covered by OSS. It also captured refunds, partial returns and marketplace fees. By structuring the data this way, Radner's team could prepare precise Danish VAT returns without overwhelming the retailer’s internal IT resources.

In the context of fiscal VAT representation in Denmark, Radner's team assumed responsibility for preparing and submitting periodic VAT returns. The retailer provided transaction files in the agreed format, and the team performed reconciliations against payment provider reports and marketplace statements. Any discrepancies, such as mismatched totals or missing refunds, were flagged back to the client for clarification. This iterative process improved data quality over time and reduced the risk of under- or over-reporting VAT.

One of the recurring challenges in the e-commerce environment was the treatment of discounts and vouchers. The retailer frequently ran campaigns with percentage discounts, free shipping and gift cards. Radner's team analysed how these promotions affected the taxable base for Danish VAT. Clear rules were established on when a voucher represented a prepayment for goods and when it was merely a marketing tool. These rules were embedded into the data extraction logic, ensuring that VAT was calculated on the correct amounts.

Another important aspect was the handling of returns, which are common in the fashion sector. Customers often ordered multiple sizes and returned part of the shipment. Radner's team clarified how to reflect these returns in Danish VAT reporting, including timing of adjustments and documentation requirements. The process ensured that VAT was reclaimed or adjusted only when the return was fully processed and recorded. This prevented premature corrections that could have triggered questions from the tax authorities.

As part of the fiscal VAT representation in Denmark, Radner's team acted as the primary contact for the Danish tax authorities. When the authorities requested explanations about high refund volumes or seasonal spikes in sales, the team provided context based on the retailer’s business model. Detailed breakdowns of sales campaigns, return rates and marketplace activities were prepared. This proactive communication helped the authorities understand that fluctuations were driven by commercial factors rather than irregularities.

During a broader sector review of cross-border e-commerce, the retailer was asked to provide additional documentation on its Danish VAT position. Radner's team assembled a comprehensive package including transaction samples, marketplace contracts and reconciliation reports. The authorities examined how the retailer distinguished between OSS and local Danish VAT reporting. Thanks to the structured framework already in place, the review concluded without adjustments. The authorities acknowledged that the retailer’s approach to Danish VAT was consistent and well-documented.

From a business perspective, the retailer gained significant advantages by stabilising its Danish VAT compliance. Management could confidently invest in targeted marketing campaigns for Danish consumers, knowing that increased sales would not create uncontrolled VAT exposure. Radner's team provided periodic overviews of Danish VAT payments and effective tax rates, which were integrated into the company’s profitability analysis by country. This transparency allowed the retailer to fine-tune pricing and promotional strategies for the Danish market.

The cooperation also reduced operational friction. Customer service teams faced fewer disputes related to VAT on invoices, refunds or customs charges. Clear VAT treatment of shipping fees and returns meant that customers received consistent information across all channels. Internally, the finance team no longer had to interpret Danish VAT rules ad hoc; instead, it relied on the established framework and the ongoing support of Radner's team. This freed up capacity for broader financial planning and analysis.

Over time, the retailer expanded its product range and introduced new categories, such as accessories and home textiles. Each new category raised questions about VAT rates and potential exemptions. Radner's team reviewed the product classifications and confirmed the applicable Danish VAT treatment. Where necessary, adjustments were made to the data extraction model to reflect different VAT rates. This ensured that growth in assortment did not compromise compliance.

Strategically, the experience in Denmark demonstrated to the retailer’s leadership that robust VAT management is a prerequisite for sustainable cross-border e-commerce growth. The fiscal VAT representation in Denmark provided by Radner's team transformed VAT from a reactive issue into a controlled, predictable component of the business model. The company could scale sales, experiment with new marketing tactics and collaborate with additional marketplaces, confident that VAT reporting would keep pace.

For high-volume e-commerce businesses, the case highlights the importance of combining technical VAT expertise with scalable data processes. Radner's team delivered both: a deep understanding of Danish VAT rules and a practical framework capable of handling thousands of transactions. As a result, the retailer not only avoided penalties and audits but also gained actionable insights into its Danish operations. This combination of compliance and business intelligence turned fiscal VAT representation in Denmark into a genuine growth enabler.
