Portfolio Company Reporting: Build It In-House or Buy It?
Read Time 18 mins | Written by: Vinayak Bhagat
Sooner or later every firm that has lived through a few quarters of chasing portfolio company spreadsheets arrives at the same fork. Either you build portfolio company reporting yourselves, in the CRM your portfolio already runs on or on a data warehouse and a BI tool, or you buy dedicated portfolio-monitoring software and let it do the collecting. Both camps will tell you their answer is obvious. It is not, because the question is usually hiding two different jobs under one name.
One job is fund reporting: standard financials, submitted by portfolio company finance teams, rolled up for the investment committee and the limited partners. The other is operating reporting: the KPIs that tell an operating partner whether the value creation plan is working, pulled from the systems each company runs. The first is what dedicated software is designed for. The second rarely fits a template, and it is where building earns its cost.
So the useful question is not build or buy. It is which job each report is doing, and which route fits that job. Four tests settle it, and most firms that run them honestly find they have some of each.
Should a PE firm build portfolio company reporting or buy software?
Run four fit tests on each report. Buy dedicated portfolio-monitoring software when the report is read mainly by the fund (the investment committee, limited partners), the metrics are standard financials, the data arrives as submissions from portfolio company finance teams, and nobody can own a pipeline. Build, in HubSpot or on a data stack, when operating partners and company leaders read it, the KPIs differ by business model, the data lives in systems you can connect, and someone will own it. When the answers split, which is common, run a hybrid: buy the fund side, build the operating side, and connect them in one direction. Settle the KPI definitions first, because both routes will faithfully automate a disagreement.
The Four Fit Tests
Apply the tests to each report, not to the reporting program as a whole. Asked in the abstract, "should we buy portfolio-monitoring software?" gets a yes from every vendor and a no from every builder. Asked of the LP roll-up and then of the operating partner's pipeline dashboard, it often gets two different, and correct, answers.
1. Audience fit: who reads it first? If the first readers are the investment committee, the valuation process or the limited partners, it is fund reporting, and what matters is consistency across companies and a defensible collection record. Dedicated software is built around exactly that. If the first readers are operating partners, portfolio company CEOs and sales leaders, it is operating reporting, and what matters is freshness, drill-down and the freedom to change what is measured when the plan changes. That leans toward building.
2. Metric fit: are the metrics standard or specific? Revenue, EBITDA, cash, headcount and the handful of lines every company in the portfolio reports the same way are standard, and a template handles them well. Pipeline coverage, stage conversion, retention by cohort, utilization or anything else that means something different in a software company than in a services business is specific, and specific metrics strain templates. The more your reporting depends on them, the more a bought tool pushes you to leave them out or keep them somewhere else anyway.
3. Source fit: does the data arrive, or can you reach it? If the data comes from portfolio company finance teams filling in a periodic submission, your problem is collection: requesting, chasing, validating and recording who submitted what, which is a core strength of dedicated software. If the data already lives in systems you can connect to, such as a CRM the portfolio has standardized on, your problem is integration, and a built pipeline reads the source instead of asking a person to retype it.
4. Owner fit: who keeps it working after a deal closes? Companies are acquired and need onboarding, others are sold and need removing, and somebody switches accounting systems mid-quarter. A built system needs a named owner who can absorb that, whether an in-house data or HubSpot administrator or a partner on a defined retainer. A bought system shifts platform maintenance to the vendor, but you still own the configuration, the definitions and every new company's onboarding. If nobody can own a pipeline, do not build one.
Reading the four answers
Four answers on the fund side point to buying. Four on the operating side point to building. A split does not mean you did the tests wrong. It means the firm is serving two audiences, and forcing one route to do both jobs is where the regret starts: a bought tool stretched to carry operating KPIs, or a built dashboard asked to produce investor reporting with a collection record it never kept.
Four Routes, and What Each Is Actually Good At
Build in HubSpot
The natural route when your portfolio companies run on HubSpot, or you are standardizing them on it, and the reporting you care most about is commercial: pipeline, conversion, retention. The data is already in one model and the operators already use the tool, so the roll-up is a matter of consistent properties and dashboards rather than a new system. Our guide to HubSpot for private equity covers the standardization that makes this work, and the worked example of automating portfolio reporting in HubSpot shows what the build looks like step by step. The limit is equally clear: a CRM is not a fund ledger, and where that line sits matters more than any dashboard.
Build on a data stack
The route when the numbers are spread across many accounting, operational and people systems and you want them modeled together: integration tooling feeding a data warehouse, a transformation layer where every KPI is defined once, and a BI tool on top. It is the most flexible route and asks the most of its owner. It rewards firms with a data capability, or a partner who will hand one over, and punishes firms that treat it as a one-off project. Our post on standardizing KPIs across portfolio companies walks through that build; we will not repeat it here.
Buy dedicated portfolio-monitoring software
The route when the core need is fund reporting. This category of software is designed around collecting standard submissions from portfolio companies, validating them, recording who reported what and when, and presenting portfolio-level results to the committee and investors. If that is most of what you need, buying is faster to value than building and spares you a maintenance burden nobody may be able to carry. The trade-off is flexibility: you work within the vendor's data model, and operating KPIs that do not fit it end up somewhere else.
Hybrid: buy the fund side, build the operating side
The most common right answer for a mid-market firm whose tests split. The bought tool owns fund reporting; the built layer owns operating reporting. They meet in one direction only, from the system that is authoritative for a figure to the one that displays it, keyed on one identifier per portfolio company that both systems agree on. Those are the same handoff rules we set out for connecting a CRM to the fund accounting system, and they apply unchanged here. The hybrid fails when nobody decides which system is authoritative for which number, so decide that on paper before anything is connected.
| Route | Best when | Watch out for |
|---|---|---|
| Build in HubSpot | Portcos are on HubSpot or being standardized on it, and the key reporting is commercial | Drifting into fund accounting; custom properties holding figures someone types in by hand |
| Build on a data stack | Many different source systems, business-model KPIs, and a real data owner | Being funded as a project and then left without an owner when the first company is sold |
| Buy portfolio-monitoring software | Fund reporting is the core need: standard financials, finance-team submissions, committee and investor readers | Stretching templates to carry operating KPIs; export and exit terms nobody read |
| Hybrid | The four tests split between fund-side and operating-side answers | Two-way sync, and no agreed identifier for each portfolio company |
Which Way Common Situations Lean
A starting position, not a verdict. Doing your own sort turns every placement into a decision someone made.
| Situation | Leans | Why |
|---|---|---|
| Quarterly roll-up for limited partners | Buy | Fund audience, standard metrics, and the collection record matters as much as the numbers |
| Monthly financial submissions from portco CFOs | Buy | A collection problem: requesting, chasing and validating is what the category is built for |
| Pipeline and conversion dashboard for the operating partner | Build | Operating audience, specific KPIs, and the data already sits in the portcos' CRM |
| Value creation plan tracking by company | Build | Each plan measures different things, and the measures change as the plan does |
| Cross-portfolio benchmarking of commercial metrics | Build | Only works once definitions are shared, which a standardized CRM or a modeled warehouse enforces |
| Board pack for a single portfolio company | Build, drawing on both | Needs the operating detail, plus the financials from whichever system is authoritative |
| Small portfolio, no data or HubSpot owner in the firm | Buy, or wait | A build with no owner decays within a few quarters; a spreadsheet you trust beats a pipeline nobody watches |
| Mixed portfolio: some portcos on HubSpot, some not | Hybrid | Build where the data is reachable, collect by submission where it is not, and roll up in one place |
When Not to Build, and When Not to Use Us
Ontrac Solutions is a HubSpot Diamond Partner and builds data platforms for a living, so read this section knowing what we are. It is here for the same reason: a firm that builds things and only ever recommends building is not giving advice.
Do not build when the job is fund reporting and nobody will own it
If what you need is standard financials collected from portfolio company finance teams for the committee and investors, and the firm has no data or HubSpot owner, buy dedicated software. Building it means recreating a collection workflow the category already does well, then maintaining it with nobody.
Do not build a fund ledger inside a CRM
HubSpot is a strong home for commercial data and for the investor relationship. It is not the system of record for capital accounts or valuations. If a build plan has the CRM holding figures that belong to fund accounting, the plan is wrong, however convenient it looks in the first month.
Do not buy or build before the definitions exist
If two portfolio companies still mean different things by recurring revenue or gross margin, either route will automate the disagreement at scale. Agree the KPI dictionary first. It costs little, and it is the step that decides whether anyone believes the numbers that come out the other end.
Do not use a build partner, including us, when all four tests say buy
If every test lands on the fund side, you do not need a build. You need a written requirements list, a disciplined evaluation of the software on the market, and a plan for onboarding each portfolio company. Spending money on custom work to avoid that evaluation is the expensive way to reach the same place.
What Drives the Cost on Each Route
We are not going to quote license fees or build budgets. Software pricing is negotiated, build costs depend on your systems, and any figure here would be wrong for your firm. What does not change is what moves the number on each route.
The build side is driven by the number and variety of source systems across the portfolio, the condition of the data in them, whether a KPI dictionary already exists or has to be negotiated first, the BI and integration tooling you license, and above all the ongoing cost of an owner: onboarding each acquisition, removing each exit, absorbing every change of accounting system. A build quoted without that ongoing cost is not cheaper. It is incomplete.
The buy side is driven by the unit the vendor prices on, which varies across the category and is worth asking about directly, the implementation and onboarding services on top of the license, the effort each portfolio company's finance team spends submitting data, what happens when you need a metric the templates do not carry, and the export terms for your own history. Ask to see a company added and one removed; both happen more often than the demo suggests.
The hybrid adds one cost the others avoid: the connection itself and the work of agreeing an identifier for each company. It is usually smaller than forcing one route to do both jobs badly, but it is not zero, and it belongs in the plan rather than a surprise invoice.
Where to Start
Start with an inventory of reports, not a demo and not a proposal. List every report that leaves the firm and every submission that comes in: who reads it, which metrics it carries, where the data comes from, how often it runs, and who produces it today. The list is usually longer than anyone expected, and both routes will be measured against it.
Then run the four fit tests on each line. If almost everything is fund-side, write requirements and evaluate software. If almost everything is operating-side and the portfolio runs on systems you can reach, scope a build with an owner named from the start. If the list splits, plan the hybrid and decide which system is authoritative for each figure before you connect anything.
Whatever the tests say, agree the KPI definitions first and name the owner second. Those two lines never move, whichever route you pick. If you are comparing outside partners for the build side, our guide to choosing a portfolio reporting automation partner covers what to ask.
The Portco Reporting Build-or-Buy Scorecard
This article explains the tests. The scorecard is where you run them on your own firm: a report-by-report inventory to fill in, a score sheet that places each report on the fund side or the operating side, a requirements list you can hand to a vendor or a build partner, and the questions to ask each of them before anyone quotes. It is the part an article cannot do for you. Enter your email and it is yours.
We build the operating side, and we will tell you when to buy the rest.
Our HubSpot practice and our data and analytics team build operating reporting across portfolio companies, in HubSpot or on a data stack, with the owner and the handover written into the scope. We start with the inventory and the four tests, and when they say the job is fund reporting that software already does well, we say so.
Run the four tests with usFrequently Asked Questions
Should a PE firm build or buy portfolio company reporting?
Decide report by report. Buy dedicated portfolio-monitoring software for fund reporting: standard financials, submitted by portfolio company finance teams, read by the investment committee and limited partners. Build, in HubSpot or on a data stack, for operating reporting: business-model KPIs from systems you can connect, read by operating partners and company leaders, with a named owner. Many firms need both, connected in one direction.
What is the difference between portfolio-monitoring software and building on HubSpot or a data warehouse?
Portfolio-monitoring software is designed around collecting standard submissions from portfolio companies, recording what was reported, and presenting fund-level results. Building on HubSpot or a data warehouse reads data directly from the systems the companies run and models whatever KPIs your value creation plans need. The first is stronger on collection and consistency; the second on operating detail and flexibility.
What does a hybrid portfolio reporting setup look like?
A bought tool owns fund reporting and its collection record. A built layer owns operating reporting. Figures flow in one direction, from the system that is authoritative for each number to the one that displays it, and every portfolio company carries one identifier that both systems agree on. The hybrid only works if those two decisions are made on paper before anything is connected.
What should we decide before evaluating portfolio reporting software?
Three things: the KPI definitions every company will report against, an inventory of every report and submission with its audience and source, and who will own onboarding and removing companies. With those in hand, the four fit tests usually make the answer obvious, and any vendor or partner is judged against your requirements rather than their demo.
