Don't let tax compliance derail your S/4 migration.
37,000+ enterprises are migrating to SAP S/4HANA. Most will discover — too late — that their tax compliance infrastructure doesn't survive the move.
The S/4HANA program journey
Taxera integrates into every phase of your migration — not as a bolt-on, but as a core workstream.

Not all compliance platforms are equal
The market is full of options. But the architecture behind the label matters more than the label itself.
US-Centric Tax Engine + Bolt-Ons
- Strong in North American tax determination
- Global compliance via acquired or partnered add-ons
- Multiple platforms, multiple contracts
- Integration complexity increases with each add-on
Designed for US tax calculation first. Global compliance is an afterthought, bolted on through acquisitions and partnerships — not a unified platform.
Legacy Software Amalgamation
- Built through years of acquisitions
- Multiple legacy codebases stitched together
- Broad coverage on paper, fragmented in practice
- Inconsistent UX across modules
A collection of acquired products, not a platform. Each module has different architecture, different support teams, different roadmaps.
Legacy Platform + Network Acquisition
- Established brand with deep market presence
- Recent acquisition of e-Invoicing network
- Integration of acquired technology still in progress
- Complex licensing models
Merging a legacy compliance platform with an acquired network creates integration debt. Customers bear the cost of convergence.
ERP-Native but Limited
- Built into the ERP ecosystem
- Basic document compliance capabilities
- Limited mandate coverage and depth
- No dedicated compliance expertise
Covers the basics but lacks the depth, coverage, and specialization that complex multinationals require. You outgrow it fast.
The Taxera approach: Born-cloud. Single platform. Global from day one.
Not acquired. Not bolted-on. Not limited. Built from the ground up as one platform for every mandate, every country, every stakeholder.

Real program outcomes from enterprise S/4HANA migrations.
Operating in 42 countries with 11 separate compliance vendors. S/4HANA migration created an opportunity to consolidate but timeline pressure was extreme.
Deployed Taxera across all 42 countries in parallel with S/4 migration. Eliminated 11 vendor contracts. Achieved compliance continuity with zero filing disruptions during cutover.
Mid-migration to S/4HANA when France and Poland announced new mandatory e-Invoicing deadlines. Existing compliance setup had no path to support these mandates on the new platform.
Taxera deployed on SAP BTP within 10 weeks. France e-Invoicing and Poland KSeF configured and tested before S/4 go-live. Tax team went from reactive to proactive.
Legacy compliance infrastructure built over 15 years — mix of local vendors, custom ABAP, and manual processes. Total compliance spend unknown across 28 countries.
Full platform consolidation onto Taxera. First time the CFO had a single view of compliance cost and status across all markets. Annual TCO reduced by 52%.
