SAP Migration Services: Scope, Timeline & Cost for UAE Businesses (2026)

Quick Answer
TACHY delivers end-to-end SAP migration services UAE businesses rely on for SAP-to-Tally and SAP-to-cloud transitions. A typical engagement runs 8–14 weeks: discovery and data profiling (2–3 weeks), chart-of-accounts remapping and rule-building (2–3 weeks), historical data extraction/validation (2–4 weeks), parallel-run reconciliation (2–3 weeks), and controlled cutover with sign-off (1 week). Fixed-fee pricing is set after a paid discovery phase; key drivers are legal-entity count, active ledgers/cost centres, years of statutory history, custom Z-reports, and inventory complexity. TACHY acts as your implementation and data-automation partner — we do not issue statutory audit opinions or hold MoF eInvoicing accreditation.

What SAP migration services UAE buyers actually need

Indian-owned groups in Dubai, Abu Dhabi and the Northern Emirates typically migrate for three reasons: licence-cost reduction, local VAT/corporate-tax compliance simplification, or consolidation onto a single cloud ERP. The scope is rarely “lift and shift.” It almost always includes:

• Chart-of-accounts remapping — SAP group COA to UAE FTA-compliant Tally or cloud COA, preserving segment reporting.
• Opening-balance reconciliation — Trial-balance tie-out at legal-entity level, including inter-company eliminations.
• Statutory history migration — UAE VAT return inputs (Box 1–9), corporate-tax adjustable income schedules, and WPS/SIF payroll history where required.
• Custom Z-report rebuild — Production variance, landed-cost, and ageing reports rewritten in the target platform.
• Parallel-run evidence pack — Month-end TB, GL drill-down, VAT return preview, and inventory valuation match for 2–3 periods before cutover.

TACHY’s SAP to Tally migration practice handles the data-engineering heavy lifting; our TACHY enterprise services layer adds AI workflow automation for reconciliations, journal approvals, and exception dashboards post-go-live.

How long does a SAP to Tally migration take?

Total calendar: 8–14 weeks for a 3-entity manufacturing group with 5 years of history. Add 2–3 weeks per additional legal entity or if inventory valuation method (FIFO vs moving average) differs between systems.

What drives the cost of a UAE SAP migration project

TACHY quotes a fixed fee after a paid discovery phase. We do not publish day-rates or per-entity prices — every variable below changes effort non-linearly:

• Number of legal entities — Each UAE trade licence (mainland, free-zone, offshore) requires separate TB sign-off and VAT registration alignment.
• Active ledgers & cost centres — 500 vs 5,000 GL codes changes mapping workshops and script maintenance.
• Years of statutory history carried — FTA expects 5 years of VAT records; corporate tax requires 7 years of adjustable-income trails.
• Custom Z-reports & user exits — Each SAP enhancement must be reverse-engineered, documented, and rebuilt.
• Inventory complexity — Batch/serial tracking, multi-warehouse valuation, landed-cost layers, and negative-stock corrections.
• Integration touch-points — Bank connectivity, POS, WMS, or eInvoicing middleware (PEPPOL/PINT AE) that must be re-pointed.

A discovery engagement (typically 10–15 consulting days) produces a fixed-fee proposal, a RACI matrix, and a risk-adjusted timeline. No surprises after sign-off.

UAE compliance checklist for migration buyers

Use this list in your vendor evaluation and internal steering committee:

• [ ] Confirm target system generates UAE VAT Return (VAT 201) XML matching FTA schema v2.1.
• [ ] Verify Corporate Tax adjustable income schedule can be produced from migrated GL balances.
• [ ] Map WPS/SIF payroll elements to target payroll or HRMS — do not assume 1:1 field match.
• [ ] Validate PINT AE / PEPPOL eInvoicing readiness — TACHY builds the outbound payload; accreditation and onboarding remain with your chosen Access Point provider.
• [ ] Document inter-company elimination rules for consolidated TB — free-zone vs mainland transfer pricing adjustments.
• [ ] Agree parallel-run tolerance thresholds (e.g., TB variance ≤ AED 1, VAT liability variance ≤ AED 0) before cutover.
• [ ] Secure source-system read-only access for 12 months post-go-live for FTA audit trail.
• [ ] Assign internal sign-off authority per legal entity (CFO or authorised signatory) — no shared generic approvals.

Common failure points we see in every third project

1. Unmapped statistical ledgers — SAP statistical postings (cost-centre assessments, internal orders) have no Tally equivalent; they must be re-engineered as MIS reports.
2. Tax-code mismatches — SAP condition-type logic (MWST, UTXJ) rarely maps cleanly to Tally VAT classifications; a manual cross-walk is mandatory.
3. Rounding differences in trial balance — SAP stores 3-decimal currency; Tally rounds to 2. Accumulated rounding on high-volume AR/AP creates AED 5k–50k TB breaks.
4. Inventory valuation method clash — Moving average in SAP vs FIFO in target creates COGS restatement; decide early and adjust opening stock value.
5. Missing attachment migration — Vendor invoices, GRNs, and payment advices attached in SAP DMS must be exported, indexed, and linked in the target or archived with audit-grade metadata.

TACHY’s automation layer flags these patterns during the profiling phase, not during UAT.

Internal audit & controls support — what we do (and don’t)

We provide technology-enabled evidence for your internal audit team: automated TB reconciliation logs, transformation-script version control, data-lineage dashboards, and exception reports tied to journal approval workflows. We do not express statutory audit opinions, certify financial statements, or guarantee regulatory approval. Your auditors remain responsible for ISA 315/330 compliance; we supply the structured data and audit trails they request.

FAQ

### Is TACHY an accredited UAE eInvoicing service provider?

No. TACHY builds the PINT AE-compliant payload and integrates with your chosen PEPPOL Access Point. Accreditation, onboarding, and certificate management are handled by the Access Point provider registered with the Ministry of Finance.

### Can you migrate 10 years of SAP history into Tally Prime?

Technically yes. Practically, we recommend migrating 5 years of detailed GL + sub-ledger data (FTA VAT retention) and 7 years of summary TB for corporate tax. Deeper history inflates validation effort exponentially; we model the cost trade-off during discovery.

### What happens if the parallel run shows a material VAT difference?

The parallel-run pack quantifies the variance by tax code, entity, and period. We root-cause the top 10 drivers (usually tax-code mapping or rounding), adjust transformation rules, and re-run. Cutover proceeds only when CFO signs off that variance is within the pre-agreed tolerance.
