M&A integration
Programme Management & Governance - M&A

Most acquisition value is lost in the integration, not in the deal.

Integration planning, 100-day execution, and value realisation tracking from day one. Independent advisory with no vendor relationships - for mid-market acquirers where synergy delivery is the measure of success.

M&A integration is the operational, technology, and people work required to realise synergies and align two businesses after an acquisition. Assured Velocity provides independent integration advisory from due diligence through the first 100 days - without vendor relationships or implementation revenue - for mid-market acquirers where integration complexity is high and internal capacity is limited.

Where M&A risk concentrates

Integration planning starts too late

Integration workstreams that begin after deal close rather than during due diligence miss the window to identify and sequence operational dependencies correctly. The first 100 days then become reactive rather than controlled.

Operating model decisions deferred

Decisions about which systems, processes, and team structures survive the integration are often deferred to avoid disruption. Deferred decisions become permanent ambiguity - and permanent ambiguity is expensive.

Cultural and people risk underestimated

Integration programmes that treat the people dimension as a communications exercise rather than a structural one suffer avoidable attrition of the talent the acquisition was made to retain.

Technology and data incompatibility

System landscapes that cannot be reconciled without significant rework - ERP, CRM, finance, and data infrastructure - are consistently the source of integration delay and cost overrun.

Governance structures not designed for integration pace

Integration requires decisions at a pace that normal BAU governance cannot support. Without a dedicated integration governance structure, decision velocity slows and momentum is lost.

Value realisation not tracked

The synergies and value drivers that justified the deal are rarely tracked with the same rigour post-close as they were modelled pre-deal - and most acquisition synergies fail at the operational level, not the strategic one. Assured Velocity builds value realisation tracking into the integration programme from day one.

What M&A covers

Assured Velocity provides independent integration leadership and advisory across the full deal lifecycle. Typical scope includes:

  • Integration readiness assessment, structured review of operational, technology, and people readiness ahead of deal close
  • Integration programme design, definition of workstreams, governance structure, and decision framework for the integration
  • Day 1 and first 100-day planning, sequenced plan for the critical early period with clear ownership and decision gates
  • Operating model design, definition of the target operating model for the combined entity with clarity on systems, processes, and organisational structure
  • Technology and data integration planning, assessment of system compatibility and definition of the integration or migration path
  • Value realisation tracking, ongoing measurement of synergy delivery against the deal thesis, with escalation paths when delivery is at risk

Independent, not conflicted

No vendor relationships, no implementation revenue. Assured Velocity's only interest is a well-governed integration that realises the deal value.

The earlier integration planning begins, the better the outcome. Start with a 30-minute call to establish where the risk is and what a useful first step looks like.

What clients say

What clients say.

“The operational due diligence found three issues that would have hit the value creation plan in the first year. We renegotiated the price.”

Operating Partner · Mid-market PE fund

“The integration programme was already stalling six weeks post-close. Assured Velocity reset the governance and got us back on plan.”

CFO · PE-backed business

“They gave us an independent view of the target's operating model before we committed. The findings changed how we structured the deal.”

Director · Lower mid-market PE fund

“The 100-day plan they built gave the portfolio company and the fund a shared view of what needed to happen and who owned it.”

COO · PE-backed services business

“System fragmentation post-acquisition was creating reporting chaos. They fixed the root cause in six weeks without disrupting the combined business.”

CTO · Acquired SaaS business

“The due diligence report was the most operationally rigorous we had seen. Gave us the confidence to proceed and the roadmap to close the gaps.”

Frequently asked questions

What M&A support do you provide and at what stage?

We work across the full post-deal lifecycle - from day-one readiness planning through 100-day integration execution and on to longer-term operating model consolidation. We do not provide deal origination or financial advisory; our expertise is in making the deal deliver its intended value once it has completed.

What are the most common reasons acquisition synergies fail to materialise?

The most common causes are: integration planning that starts too late (after signing rather than during due diligence), underestimating cultural and people friction, technology integration that is more complex than assumed, insufficient leadership attention once the deal closes, and benefits targets that were set without a credible delivery plan behind them.

How quickly should integration planning start after a deal is announced?

Ideally integration planning begins during the due diligence phase, so that day-one is operationally ready before the deal closes. In practice, many organisations start late and use the first weeks post-close to catch up. The later planning starts, the higher the cost and the greater the risk to business continuity.

What does a 100-day integration plan actually cover?

A 100-day plan covers: legal and regulatory day-one requirements, leadership and governance structure for the combined entity, immediate people and communication priorities, identification of quick-win synergies, technology access and data sharing arrangements, customer and supplier communication, and the sequencing of deeper integration workstreams beyond day 100.

How do you handle situations where the acquired business resists integration?

Resistance is normal and usually reflects anxiety about job security, loss of autonomy, or distrust of the acquiring leadership. We address this through transparent communication, early involvement of acquired business leaders in integration decisions where appropriate, and clear signalling about which elements are non-negotiable versus where genuine flexibility exists.

Can you support a private equity-backed acquisition specifically?

Yes - PE-backed acquisitions have specific dynamics: compressed timelines, value creation plans with defined financial targets, and investor reporting requirements. We understand EBITDA-driven integration priorities and can align integration activity directly to the metrics that matter to the investment committee.

What technology integration challenges are most common after an acquisition?

The most common issues are: incompatible ERP or CRM systems with no clear migration path, data that cannot easily be extracted from the acquired business's systems, shared infrastructure with unclear ownership, and two IT teams with different standards and ways of working. Technology integration typically takes two to three times longer than initially estimated.

Do you work alongside the acquirer's existing internal team?

Always. We work alongside internal teams rather than replacing them. Our role is to provide the senior integration leadership, the governance structure, and specialist expertise that accelerates delivery - not to take over. Internal teams retain ownership of outcomes.

What is a post-acquisition operating model review and when should it happen?

A post-acquisition operating model review typically happens 6-18 months after close, once the immediate integration is complete. It asks whether the combined entity is actually operating as intended, whether the synergies have been realised, and what the target operating model should be for the next phase of growth. It often surfaces issues that were de-prioritised during the initial integration push.

How do you measure the success of an M&A integration engagement?

Success is measured against the specific synergy targets and integration milestones agreed at the outset - not against generic consulting metrics. We track financial synergy realisation, operational KPIs agreed with the leadership team, and qualitative indicators such as retention of key people from the acquired business.

All engagements are led by senior practitioners - not junior teams.
