ERP Selection & Implementation Support: After Approval: What Continues
ERP Selection & Implementation Support does not end at approval — a set of obligations continues afterwards. The questions below are the ones raised most often in practice; the full scope of the service is on the ERP Selection & Implementation Support page.
What is the realistic cost of an ERP implementation, and does PNPC help estimate this?
ERP costs vary widely by platform, module scope, user count, customisation depth, and whether implementation is on-premise or cloud-hosted — from a modest per-user monthly subscription for a cloud accounting-led platform to a substantial multi-year investment for an enterprise ERP with manufacturing and multi-entity consolidation. Because the range is genuinely wide and situation-specific, PNPC does not quote a single figure without first understanding your requirement scope; instead, we build a structured total cost of ownership comparison across shortlisted vendors during the evaluation phase, covering licensing, implementation, data migration, training, and annual maintenance costs that are frequently under-quoted in headline vendor pricing.
In practice: The gap between a vendor's headline quote and the actual first-year total cost is a common source of ERP budget overrun. We insist on a genuine multi-year total cost of ownership comparison before any commercial decision, not a licence-fee-only comparison.
Does PNPC provide ongoing support after the ERP goes live, or does the engagement end at go-live?
The core engagement includes a formal post-implementation review to confirm the requirement study's original objectives were achieved and to identify adoption gaps. Many clients also engage PNPC on a continuing advisory basis — for periodic roadmap reviews at business milestones (new entity, new state, new statutory requirement, or significant transaction growth), for additional module rollouts, and for ongoing GST/TDS/payroll compliance services that run on top of the implemented ERP.
In practice: Systems that were right for a business at a smaller scale often become the bottleneck at a larger one if never revisited. We recommend at least an annual roadmap check-in even for clients who do not need continuous advisory support.
Why should we engage PNPC rather than relying entirely on the ERP vendor's own implementation consultants?
A vendor's implementation consultants are skilled at configuring their specific software, but they are not trained in, and are not incentivised to independently validate, Indian GST, TDS, and Companies Act compliance requirements, or UAE VAT and Corporate Tax requirements where relevant. PNPC is a practising CA firm. We are present at requirement definition, through vendor-neutral selection, through chart of accounts design, and through the build and stabilisation phases — with the statutory and financial-control lens as the throughline, not an afterthought.
In practice: A vendor-led-only implementation can leave one or more of: a chart of accounts that does not map to GST/TDS reporting, missing or generic TDS configuration, an audit-trail gap flagged by the statutory auditor, or a control/segregation-of-duties weakness.
What does the PNPC ERP advisory package actually include, in full?
Current-state assessment and stakeholder discovery. Formal requirement study documentation covering modules, transaction volumes, and statutory obligations. Vendor shortlisting, structured RFP process, and scenario-based demonstration evaluation. Total cost of ownership comparison across shortlisted vendors. Final selection recommendation report and commercial/contract terms review. Chart of accounts and tax mapping design aligned to GST, TDS, and Schedule III requirements. Process and controls redesign for segregation of duties and audit trail. Implementation oversight against the approved design through the build phase. Data migration validation and opening balance reconciliation. Parallel run coordination and reconciliation for at least one full compliance cycle. Go-live and stabilisation support for the first live compliance cycle. Formal post-implementation review.
In practice: The full package above is scoped and priced by phase — a client can engage us for the requirement study and selection phases only, or for the complete journey through post-implementation review. We agree the exact scope in writing before starting.
Does PNPC get involved if we are switching from one ERP to another, rather than adopting one for the first time?
Yes. ERP-to-ERP migration (for example, moving from Tally to a fuller ERP, or from one enterprise platform to another after an unsatisfactory first implementation, a merger, or an outgrown legacy system) follows a broadly similar structure to a first-time adoption — requirement study, vendor evaluation if the platform itself is changing, chart of accounts redesign, data migration, and parallel run — with the added complexity of migrating a larger volume of historical transaction data and often correcting configuration issues carried over from the legacy system.
In practice: Migration engagements often surface more historical data-quality issues than first-time adoptions, simply because there is more transaction history to reconcile. We build additional time into the data migration validation phase specifically for migration (as opposed to first-time adoption) engagements.
How does PNPC ensure the ERP recommendation is not influenced by which software is easiest for PNPC's own accounting team to work with?
Our accounting and compliance teams are trained across the major platforms we commonly recommend — Tally Prime, Zoho Books, SAP Business One, Microsoft Dynamics 365 Business Central, NetSuite, and Odoo among them — specifically so that platform familiarity is not a factor that could bias a recommendation. The requirement study and vendor evaluation criteria are documented and weighted before vendor demonstrations begin, and the final recommendation is scored against those pre-agreed criteria.
In practice: We document the evaluation criteria and weighting before demonstrations start, precisely so that the final recommendation can be defended against the documented requirement, not against which platform felt most familiar in the room.
Can PNPC help with training and change management, or only the technical/compliance design?
Change management and user training are part of the full engagement scope, though the hands-on software training itself is typically delivered by the implementation partner or vendor, with PNPC ensuring the finance and compliance team specifically receives training on the GST/TDS-relevant workflows (not just generic software navigation) and validating that the team can independently operate the system correctly before we sign off on go-live readiness.
In practice: Generic software training frequently skips the compliance-specific workflows — how to correctly book a TDS-applicable vendor invoice, how to handle a multi-GSTIN stock transfer — because the vendor trainer is not a CA. We insist on a dedicated compliance-workflow training session as part of go-live readiness.
Where this sits in the wider engagement
ERP Selection & Implementation Support rarely arrives on its own. The statutory basis and the current requirements are set out on the ERP Selection & Implementation Support service page, and the related services are grouped under Business Transformation.
What PNPC does
PNPC Global has practised since 1986 across India and the UAE. On ERP Selection & Implementation Support we take the work end to end — reviewing the facts, preparing and filing what is required, and dealing with the authority through to closure.
