How this list works

  • Entries come from each vendor's own website, checked on the date shown. Figures marked “vendor figure” are the vendor's own claims.
  • Within each category the order is alphabetical. There is no ranking.
  • Pipeline-focused deal CRMs (DealCloud, Affinity and others) are in our deal origination tools directory.
  • Vedekon has no commercial relationship with any vendor or organiser listed, and no link here is an affiliate link.

Do you need dedicated software?

Many integrations run on a shared workbook and a weekly meeting, and run well. Dedicated M&A software starts to pay when the same team integrates several acquisitions a year, when many workstreams depend on each other, or when synergies must be reported to a board in the same form every time. What the software cannot do is decide the integration approach, own the synergies or keep key people; those stay with management. Our guide to post-merger integration covers that part.

  • Playbooks: a reusable plan for each type of deal, so the tenth add-on is integrated like the second.
  • Synergy tracking: baselines, owners, one-off costs and actuals, reported the same way as the accounts.
  • Diligence-to-integration handover: findings from diligence becoming integration tasks without being re-typed.
  • Access for outsiders: advisers and the target's managers working in the same plan, with the right permissions.
