Post-Merger Integration Services

End-to-end post-merger integration covering 100-day planning, HR and cultural alignment, IT harmonisation, and synergy tracking.

Service overview

Post-merger integration support designed to help organisations combine businesses, teams, systems, processes, and operations following a merger, acquisition, or similar transaction
The service covers development of an integration roadmap and 100-day plan, HR and cultural alignment, IT systems and process harmonisation, and ongoing tracking and realisation of transaction synergies

Acquiring companies, merged entities, promoters, private equity investors, strategic investors, and management teams responsible for integrating an acquired or combined business
It is required after signing or closing a transaction where people, processes, technology, systems, reporting structures, operating models, or organisational cultures need to be brought together while maintaining business continuity
Integration planning is commonly initiated before or around closing so that Day 1 and early post-closing activities can be executed in a controlled manner

WCP professionals support you with:

Assessment of the transaction objectives and integration scope, preparation of an integration roadmap, identification of critical Day 1 and 100-day activities, coordination of functional integration workstreams, review of HR and organisational issues, support for cultural alignment, identification of technology and process dependencies, monitoring of integration milestones, and structured tracking of expected cost, revenue, or operational synergies.
A typical integration framework uses defined workstreams, accountable owners, milestones, dependencies, risk tracking, and an integration governance mechanism.

Initial integration planning and Day 1 readiness may be developed within an agreed professional timeline, while execution generally continues through the first 100 days and may extend considerably longer depending on the size, complexity, geography, technology environment, workforce, regulatory requirements, and degree of operational integration.
The first 100 days are commonly used as a structured early-stage integration period, with longer-term workstreams continuing thereafter.

Professional integration support does not ordinarily involve a fixed government fee.
Government charges, statutory filing fees, stamp duty, registration costs, regulatory approval fees, and other transaction-related expenses may arise depending on the underlying M&A transaction and the legal structure of the combined business.
Timelines depend on transaction closing, regulatory requirements, employee and contractual matters, systems migration, operational dependencies, and management decisions.
Key outcomes include business continuity, aligned organisational structures and processes, integrated systems, clearer governance, measurable synergy targets, and progressive realisation of the commercial objectives identified in the transaction.

Depending on the transaction, integration may involve MCA filings, changes to corporate records, board or shareholder resolutions, employment and payroll documentation, regulatory notifications, FEMA/RBI filings for applicable cross-border transactions, SEBI or stock-exchange filings for applicable listed entities, licences or registrations requiring amendment or transfer, and other sector-specific submissions.
The exact filings depend on the transaction structure, entities involved, business sector, and applicable regulatory requirements.

Integration should be planned around clearly defined ownership, milestones, dependencies, decision-making authority, and escalation mechanisms.
Employee communication, retention of critical personnel, customer and supplier continuity, regulatory compliance, data security, systems migration, contractual obligations, and business continuity should be considered throughout the process.
Cultural integration should not be treated as a purely administrative exercise, while technology integration should account for legacy systems, data dependencies, cybersecurity, access controls, and migration risks.
Synergy targets should be measurable, assigned to responsible owners, tracked against defined baselines, and periodically reviewed rather than being left as optimistic numbers in the original deal model.

A structured post-merger integration programme commonly progresses through Day 1 readiness, the first 30 days, the 31-100 day integration period, and longer-term optimisation.
Functional workstreams may include Finance, HR, IT, Legal, Operations, Sales, Communications, and other business functions depending on the transaction.
An Integration Management Office or equivalent governance structure may be established to coordinate workstreams, monitor milestones, escalate issues, and report progress to senior management.
Synergy tracking should continue beyond the initial 100-day period until identified value-creation initiatives are embedded into normal business operations.

The estimated cost covers indicative professional fees only. Government fees, stamp duty and taxes are payable at actuals.

Why do mergers fail to deliver value?

Often because integration of people, systems and processes is poorly planned or slow.

What is a 100-day plan?

The priority actions for the first 100 days after closing — governance, key people, customers, systems and quick wins.

How are synergies tracked?

Against a baseline, with owners and milestones for each cost and revenue synergy.

Which compliance steps follow a merger?

Updating registrations, licences, bank accounts, contracts, tax registrations and employee records.
