TACHY plans and runs SAP, Tally and legacy-system migrations for education groups and growing businesses — with the discipline of an audit, not just a data copy. Every migration ends in a line-by-line reconciliation, a documented variance analysis, and an audit-ready report your finance team and auditors can sign off on.
Finance, admissions, HR/payroll and operational records that a board, an auditor or a regulator will eventually ask about.
Each engagement is scoped from this list during Discovery — not every project needs every line item.
| Capability | What it covers | |
|---|---|---|
| 01 | SAP, Tally & legacy-system migration | Planning and execution of the move itself — source-system extraction, target platform setup, and a phased cutover sequence. |
| 02 | Financial & transactional data migration | Ledgers, vouchers, invoices, payroll and transactional history moved with full audit trail, not just closing balances. |
| 03 | Data mapping, cleaning & transformation | Chart-of-accounts mapping, duplicate and gap detection, currency/format normalization before a single record moves. |
| 04 | Ledger & trial-balance reconciliation | Source-to-target reconciliation at the ledger and trial-balance level — the step most migrations skip, and the one that matters most. |
| 05 | Variance analysis | Every mismatch traced to a specific cause — mapping rule, timing difference, rounding, duplicate — and resolved, not written off. |
| 06 | UAT & production migration | A rehearsed sample migration and user-acceptance round before the real cutover, with a tested rollback plan. |
| 07 | Audit-ready migration reports | A documented package — what moved, what was reconciled, what variances existed and how they were closed — for your auditors. |
Four phases. Each ends with a concrete artifact your team reviews before the next phase starts — no open-ended engagements.
The deliverable is a matched trial balance and a signed-off variance report — a successful file transfer alone is not treated as done.
The same team scopes, migrates, reconciles and hands over — no split accountability between a migration vendor and a separate reconciliation vendor.
Reports are structured for your existing CA/audit relationship to review and sign off — this practice does not replace your auditors' authority over the numbers.
Discovery produces a fixed scope and quote before commitment. No hourly-billing engagements with no defined end state.
A scoped review of your current system, data quality and migration risk.
The core engagement — data moved, reconciled, and signed off.
Stabilization after go-live, with an option to continue as ongoing managed support.
Every engagement runs a parallel reconciliation: source-system totals (ledgers, trial balance, subsidiary registers) are checked line-by-line against the migrated target before cutover, not after. Nothing is marked complete until the numbers match or every variance is explained and signed off.
It is treated as a defect, not an acceptable outcome. Every variance is traced to its cause — a mapping rule, a currency or rounding difference, a duplicate or missing transaction — corrected, and re-reconciled. Production cutover does not proceed on an open, unexplained variance.
Yes — that is the intended setup. TACHY handles the technical migration and reconciliation workstream; your auditors or CA retain sign-off authority on the numbers. Audit-ready reconciliation reports are a deliverable specifically so your existing finance and audit relationships stay in control.
It depends on data volume, number of source systems and how clean the source data already is — which is exactly what the Discovery phase scopes and quotes before any commitment. There is no fixed-price, one-size-fits-all package for this reason.
Data-handling, access control and retention decisions are agreed explicitly during the Data Governance workstream before migration begins, not assumed. Scope, storage location and who has access to production financial data are documented up front.
Education groups are where this practice started and remains deepest, but the migration and reconciliation discipline — SAP, Tally, legacy ERP, financial data — applies the same way to any growing business moving off a legacy system.
