Consolidating Your SaaS Stack After a Merger

List every category where both companies have a tool doing roughly the same job, and resist the urge to start deciding while you're still inventorying. A merger often surfaces tools nobody outside their original team even knew existed, especially in categories like time tracking or lightweight project management where individual teams sometimes adopt a tool without a formal procurement process, and those quiet adoptions are exactly the ones that get missed if the inventory only covers officially sanctioned software.

Moving from one project management tool like ClickUp to another isn't just a licensing decision, it's a data migration project with real risk of losing history, breaking integrations, or disrupting a team mid-project. Estimate the migration effort honestly for each direction, not just the ongoing subscription cost, since the cheaper tool on paper can turn out to be the more expensive overall choice once migration risk and disruption are properly priced in.

For example, suppose the cheaper of two project tools holds years of task history, custom fields, and integrations, while the pricier one holds very little. Moving everyone onto the cheaper tool means migrating almost nothing, but moving everyone onto the pricier tool means rebuilding integrations and risking lost history. Price both directions: migration effort, integration rework, retraining time, and disruption to projects in flight. Compare those totals rather than the subscription lines. If the totals come out close, pick the direction that touches fewer active projects, and schedule the move for a quiet stretch instead of the middle of a launch.

A single committee deciding every tool category at once tends to produce political compromises rather than good decisions, since nobody on a broad committee has deep context on every category being decided. Assign one owner per tool category, someone who genuinely understands both companies' usage of that specific tool, and let them make the call with a clear decision framework rather than putting every choice through a company-wide vote.

Migrating every overlapping tool simultaneously multiplies disruption at exactly the moment a newly merged team needs stability most. Sequence consolidation by urgency and complexity: low-risk, low-complexity tools first to build momentum and confidence in the process, higher-risk systems like the CRM or financial tools later, once the team has practice running a migration well and has learned from whatever went wrong on the easier ones.

Sequence the consolidation in this order:

1. Start with low-risk, low-complexity tools that hold little data and few integrations, so the team practices migration on something forgiving.
2. Record what went wrong on each early migration and adjust the checklist before starting the next one.
3. Move mid-complexity tools once the process runs smoothly and teams have seen a migration go well.
4. Leave the highest-risk systems, such as the CRM and financial tools, for last, when the team has real practice.
5. Explain each decision and its criteria to the affected team before the migration date, not after.

Treat stack consolidation as a tracked project, not a background task someone handles between other responsibilities. A workspace like ClickUp can hold the migration plan itself, while a time-tracking tool like Toggl helps estimate how much staff time consolidation work is actually consuming, information worth having if leadership starts asking why the process is taking longer than expected.

Whichever tool loses in each category, the team that used to rely on it needs to understand why, not just receive a migration date with no context. A brief note explaining the decision criteria and how they were applied reduces the resentment that otherwise builds when a team feels like their tool was discarded arbitrarily rather than through a fair process they can actually see.

A tool switch is a genuine loss for the team giving theirs up, even when the decision was clearly the right one on the merits, and treating it as a purely logistical exercise misses that. Give the losing team a real say in the migration timeline and training plan, even if they had no say in the tool decision itself, since some input over how the change happens does a lot to soften how a decision they didn't choose actually lands day to day.
