Almost no advisory practice chose its software stack. It accumulated one.
The pattern is consistent. A core planning tool came first, probably chosen years ago. Then a spreadsheet appeared for the corporate work the main tool could not handle. Then a separate calculator for CPP timing, because the built-in one was too crude. Then an insurance needs tool. Then a second spreadsheet, the one nobody else in the office fully understands, for the two or three clients who do not fit anywhere.
Every one of those additions was rational. Each solved a real gap at the moment it appeared. The result is still a stack nobody would have designed on purpose.
The Cost Is Not the Subscriptions
Advisors evaluating consolidation usually add up the licence fees. That is the smallest number in the equation.
The real costs are quieter.
Re-entry. Every tool needs the client's situation entered into it. The same date of birth, the same account balances, the same assumptions, typed repeatedly. Beyond the time, each re-entry is an opportunity to introduce a discrepancy that nothing will catch.
Drift. This is the serious one. Your main platform assumes a 5% return and 2% inflation. The spreadsheet you built in 2023 assumes 6% and 2.5%, because that was reasonable when you built it. Both produce plausible output. They disagree, and nothing in either tool will ever tell you so.
Reconciliation. When two tools produce different answers, someone has to work out which is right. That work is invisible, unbillable, and lands on whoever notices first.
Version ambiguity. Six months after a client meeting, which projection did you actually present? The one in the platform, or the spreadsheet version with the revised assumption? If those disagree, the file is unclear about what you recommended.
That last one is the compliance exposure, and it is worth sitting with. Your obligation is to have a reasonable basis for a recommendation and to be able to explain it. A stack where the numbers depend on which file you opened makes that obligation harder to discharge, not because anyone did anything wrong, but because the record is ambiguous.
What Consolidation Actually Buys
The benefit of a single platform is not that it has more features. Any sufficiently mature point tool will beat a platform's equivalent module on depth. That is what specialization does.
The benefit is that one set of assumptions governs everything.
Change your inflation assumption once and every projection, every scenario, every report reflects it. The estate number and the retirement number were produced by the same engine, so they agree by construction rather than by your diligence. When a client asks how the incorporation decision affects the retirement date, that is one question inside one model rather than a manual exchange between two tools.
There is a second benefit that matters more over time. A consolidated stack produces a coherent record. The plan you presented in March is reproducible in September because there is one place it lives and one engine that generated it.
When Point Tools Are Genuinely Right
Consolidation is not always the answer, and a vendor telling you otherwise is selling.
Point tools win when the specialization is deep and the output is self-contained. Highly technical estate work, complex insurance structuring, and specialized tax analysis are all areas where a dedicated tool run by someone who knows it well will beat a general platform's module. The same is true when the work genuinely sits with a specialist rather than with you.
The distinction that matters is whether the tool's output feeds back into the plan. A specialist tool that produces a standalone deliverable is fine. A tool whose numbers have to be manually carried back into the main projection is where drift enters, and that is the case worth consolidating.
Put plainly: keep the point tool if it ends a conversation. Consolidate it if its answer has to be retyped somewhere else.
Questions to Ask Before Consolidating
Which of my current tools actually feed the plan? Map it before you shop. Most practices are surprised by how many hand-offs exist.
Where do my assumptions currently live? If the answer is "in several places," you already have drift, whether or not you have found it yet.
What is my genuine edge case volume? If two clients a year need the specialist tool, that is not an argument against consolidating the other ninety-eight.
Can the platform handle the file that pushed me to a spreadsheet in the first place? Test that specific client, not a clean hypothetical. This is the whole evaluation.
What happens to my historical plans? Consolidation has a migration cost. Ask what comes across and what does not.
The Realistic Path
Few practices consolidate everything at once, and the ones that try tend to stall.
A more reliable sequence is to consolidate the work that flows into the plan first, which is usually the retirement projection, the tax modelling, and the client-facing reporting. Leave genuinely specialized tools alone until the core is stable. Then reassess, because a stronger core often absorbs a point tool you assumed was permanent.
The test at each step is the same: does removing this tool eliminate a hand-off where a number gets retyped? If yes, consolidating it reduces risk as well as effort. If no, leave it and move on.
The Underlying Point
A stack of tools is not a neutral arrangement. It has a running cost that appears as time nobody logged, discrepancies nobody traced, and a file that cannot quite reconstruct what was recommended.
None of that shows up on a subscription invoice, which is exactly why it persists. It is worth pricing anyway, because it is the actual cost of the arrangement, and it grows with the complexity of the clients you serve.
The goal is not fewer tools for its own sake. It is a set of numbers that agree with each other, and a record you can reconstruct.
PlanBase runs retirement, tax, corporate, estate and portfolio work through one engine, so a change to an assumption updates every projection and report at once.
