How Walter Tools Prepared Its SAP Tax Operations for the Tax Reform

Headquartered in Germany with a strong presence in the Brazilian market, Walter Tools is a leading global benchmark in the development and manufacturing of high-precision cutting tools for turning, milling, drilling, and threading. Serving highly demanding industries (such as automotive, aerospace, and energy), the efficiency of its supply chain and billing operations relies on a robust and frictionless technological infrastructure.

To support its complex operations in Brazil, the company relies on the processing power of the SAP ecosystem, managing a high volume of invoices (notas fiscais) and meticulous business rules.

The Challenge

With the advancement and regulation of the Brazilian Tax Reform (introducing the Dual VAT framework through IBS and CBS, as well as the Selective Tax), Walter Tools faced a critical scenario. The traditional tax operations mapped out within SAP needed to be completely remodeled to support the transition period, destination-based tax rates, and Split Payment rules (tax collection upon financial settlement).

The main obstacle lay in the structural rigidity of the ERP and the risk of obsolescence within legacy messaging solutions. Walter Tools required a strategy that:

Guaranteed Continuous Tax Document Compliance: Ensured the continuous issuance and reception of tax documents (NF-e, NFS-e) in full compliance with the new standards required by tax authorities, without disrupting billing operations at manufacturing plants and distribution centers.
Eliminated Complex ERP Customizations: Avoided complex customizations inside SAP, preventing the accumulation of technical debt and astronomical consulting costs.
Provided Strategic Simulation Tools: Offered tax intelligence and scenario simulation capabilities so that the tax transition would remain completely transparent to both the global headquarters and machining customers.

It was at this moment of transformation that TTAX was chosen as the strategic partner to lead this technological shift.

The Solution

TTAX implemented an integrated ecosystem that combined processing agility with the robust fiscal compliance required by Walter Tools’ SAP environment. The architecture was built upon two fundamental pillars:

1. Messaging (SAP Outbound NF-e)

To shield billing operations against communication failures and ensure real-time compliance, TTAX’s Messaging solution was deployed.

Frictionless Integration: Operating transparently and fully connected to Walter Tools’ SAP system, the messaging tool ensures the secure processing and rapid transmission of invoices, optimizing the performance of the company’s internal infrastructure.
Ready for the New Standard: A flexible architecture that updates automatically to the new layouts required by the Tax Reform, absorbing changes within XML files without demanding new internal IT projects.

2. TaxOrion Fiscal Solution (for SAP Clients)

To serve as the core engine of tax operations during and after the transition, the TaxOrion Fiscal Solution was implemented.

Native Development (ABAP/Fiori): TaxOrion runs directly within Walter Tools’ SAP environment. This means the company’s tax and accounting teams manage the new Tax Reform rules through familiar interfaces, eliminating the need to switch systems or undergo repetitive, time-consuming training sessions.
Calculation and Auditing Engine: TaxOrion took over the automatic and precise determination of CBS and IBS, securing the pricing of precision tools from end to end and generating the compliance reports required by global headquarters.

The Result

The synergy between Walter Tools’ German engineering and TTAX’s tax and technological DNA transformed a moment of regulatory uncertainty into a sustainable competitive advantage. The primary results include:

Agility and Business Continuity: Zero risk of disruption to shipping operations. The messaging solution ensured that billing streams for critical clients continued running at maximum speed.
Immediate User Adoption (Time to Value): Because TaxOrion is natively integrated via SAP Fiori, the internal Walter Tools team’s learning curve was drastically reduced. The operational department absorbed the new IBS/CBS concepts seamlessly.
Significant IT Cost Reduction: Eliminated the need for in-house development and manual tax table maintenance within SAP. TTAX handles the legal evolution of the tool, generating continuous savings on consulting hours.
Global Transparency: Walter Tools Brazil now reports to its global headquarters in Germany with absolute accounting security, proving local compliance through auditable processes that fully align with the transition rules of the Brazilian Tax Reform.
