Avoid the hidden traps
of post-M&A tech integration!

This field-tested checklist helps skip the most common mistakes & keep the business running while tech merges behind the scenes.

What will you find inside?
7 essentials for post-merger integration done right:
-
What to prioritise in the first 90 days
-
How to untangle legacy stacks without causing downtime
-
Signs your integration is heading for trouble
-
What metrics actually matter (and what to ignore)
-
How to prep for AI without slowing the integration
-
Keeping data secure and useful
-
How to hold your team together under pressure


“The deal closes, the victory lap isn’t even over, and we’re already on the clock. Roadmaps clash, systems don’t sync, and the pressure builds fast. Integration success depends on decisions made in those first 90 days—and too often, tech leads haven’t had a real seat at the table.”
Alex Vezenkov, Lead Software Engineer at Pwrteams

Why do you need it?
Because integration failure isn’t a tech problem, it’s a planning problem.
Too many fintech mergers stall because teams dive into coding before aligning on business context, architecture, or even who’s doing what. The result? Duplicate work, lost time, fragile systems, and frustrated teams.
This checklist helps you:
-
Avoid the early mistakes that snowball into rework
-
Build the right foundations for scalability
-
Keep customer impact to a minimum
-
Get clarity on what to preserve, rebuild, or retire
-
Lead your team through chaos without burning them out
You don’t need a 100-page strategy deck.
You need a sharp, proven plan for the messy middle. This is it.
Is this just another generic checklist?
Nope. It’s built by engineers who’ve been through actual fintech integrations, messy ones. It’s field-tested and brutally practical.
Will it help with our specific tech stack?
How detailed is it?
Detailed enough to save you weeks of rework, short enough to use before your next sync. It’s a quick read, not a whitepaper.
