We specialize in helping global organizations streamline indirect tax operations, slash operational and software expenses, and engineer high-throughput integrations across E-Commerce, ERP, and Retail POS ecosystems.
Core Competencies
Our experienced architects and engineers bring deep subject-matter expertise from dozens of enterprise implementations across E-Commerce, ERP, and Retail systems—helping you implement faster, reduce risk, and unlock measurable business outcomes.
Comprehensive expertise of O Series on-premise, cloud-hosted, and containerized architectures. We help organizations overcome in-house skill gaps, optimize license and operational costs, tune batch and web-service calculation throughput, and evolve complex multi-channel integrations.
End-to-end engineering for multi-entity tax determination, exemption certificate lifecycle management, and high-velocity API integration. We eliminate latency bottlenecks and reconcile transaction data flows across ERP, billing, and digital commerce stacks.
Specialized implementation and integration expertise for global indirect tax determination. We streamline cross-border VAT, GST, and US sales and use tax data pipelines to ensure governance, internal controls, and audit-ready accuracy at scale.
Engineering Capabilities
Standard tax engine installations often leave critical operational gaps. We bridge those gaps with elastic cloud-native architectures, universal retail POS translation layers, web-based batch portals, and automated testing pipelines.
Transition from high-overhead on-premise VMs to an extensible "Infinity Architecture"—combining unlimited horizontal tax calculation web-service instances with a dedicated core reporting instance. Enjoy zero-downtime maintenance, automatic software patching, customizable monthly tax updates, and frictionless cloud marketplace procurement that draws down your existing AWS, GCP, Azure, or OCI commit.
Extract, interpret, and transform complex tax outcomes from your indirect tax engine into both flat tax files and structured relational data. Built to be completely platform-agnostic (IBM AIX, Linux, Windows) and database-agnostic (IBM DB2, Oracle, SQL Server) with proven compatibility across IBM, Oracle (Store21 / Xstore), Cornell Mayo (CMA), Epicor, and Island Pacific POS systems—without costly re-platforming.
Import, manage, and troubleshoot offline ERP and point-of-sale tax transactions through an intuitive web portal rather than legacy command-line batch interfaces. Streamline bulk file validation, job scheduling, exception diagnostics, and reconciliation to accelerate high-volume billing runs and financial close cycles.
Replace manual spreadsheet verification with continuous, automated tax scenario testing. Replay thousands of historical and edge-case transactions across ERP payloads, exemption rules, and jurisdictional rate updates to guarantee calculation accuracy before changes ever reach production.
Value Differentiators & Cost Optimization
We empower tax and IT leaders with data sovereignty, update timing control, and cloud-native efficiency—slashing operational expenses by simply switching endpoint URLs while preserving full access to transaction tax data.
Comply with country and organization-level data protection guidelines while retaining direct, unrestricted access to your transaction tax data for reporting, audit defense, and cloud analytics.
Manage the exact timing of tax engine updates, patches, and system changes to align with your internal freeze windows, project schedules, and customized integration requirements.
Achieve 40–60% lower operational overhead, eliminate hardware and maintenance CapEx/OpEx, and procure through your preferred cloud marketplace to draw down existing cloud spend commitments.
| Consideration Factor | Self-Hosted On-Premise VM | Vendor-Hosted On-Demand VM | TAG Cloud-Native Managed Architecture |
|---|---|---|---|
| Infrastructure & TCO | High upfront hardware, software & IT overhead | Medium subscription cost, rigid tiering | Low operational cost (40–60% OpEx savings); leverages cloud commit |
| Maintenance Downtime | Yes (manual outage windows) | Yes (scheduled vendor windows) | None (non-disruptive, zero-downtime operations) |
| Tax Updates & Patches | Manual internal administration | Automatic on fixed vendor schedule | Automatic & customizable to your business schedule |
| Availability & Scale | Limited to fixed VM capacity | Limited single-cloud scaling | Unlimited elastic web-service instances & non-prod clusters |
| Deployment Flexibility | Single datacenter | Single cloud, single zone | Multi-cloud (AWS, GCP, Azure, OCI), multi-zone global reach |
| Subject-Matter Expertise | Internal burden / costly external hourly rates | Extra fee-based advisory | Included production cluster support & specialist engineering |
Technical Engagement Model
Re-focus your organization's resources on higher-value strategic activity while our specialists handle complex tax engine configurations, cloud migrations, POS data translations, and ongoing administration.
Unlike rigid shared-tenant platforms that dictate fixed maintenance windows and restrict database access, our architectures preserve your data sovereignty. You maintain direct access to structured transaction tax data and control when software patches and monthly tax updates are promoted into production.
Our retail tax data service is both operating-system agnostic (IBM AIX, Linux, Windows) and database agnostic (IBM DB2, Oracle, Microsoft SQL Server). It translates complex tax rules into both flat files and relational data formats compatible with IBM, Oracle (Store21 / Xstore), Cornell Mayo (CMA), Epicor, and Island Pacific POS systems without requiring middleware or re-platforming.
Our cloud-native deployments can be procured directly through major cloud marketplaces (AWS, Google Cloud, Azure, and OCI), allowing you to simplify billing, draw down existing cloud commitments, and lock in predictable 1-, 3-, or 5-year terms—often cutting operational and infrastructure expenses by 40–60%.
We provide fixed-fee cloud migrations, custom solution design, ERP and e-commerce connector engineering, automated regression testing, and dedicated specialist support channels with proactive defect and enhancement tracking.
