Should a fund build or buy LP reporting automation?
Updated
Most funds should buy the reporting layer and build only what is unique to them. Building in-house means owning data connections, report templates, review workflows and audit trails indefinitely, plus the people who maintain them. Licensing shifts that upkeep to a vendor. Build makes sense when reporting is genuinely a source of advantage and you already run an engineering team.
The first version of an in-house reporting tool is rarely the expensive part. The cost comes later: every new fund, investor request, regulator change and staff departure needs someone to update the system.
Compare both options on the full lifetime cost, not the build estimate. Include the people who maintain it, the time to the first quarterly report, and how easily an auditor can trace a figure back to its source.
How Reuben AI compares
Building and licensing LP reporting automation compared.
| Attribute | Reuben AI | Build |
|---|---|---|
| Upfront effort | Licence: configuration and data mapping | Design, engineering and testing |
| Ongoing upkeep | Licence: handled by the vendor | Your team, indefinitely |
| Audit trail | Licence: usually built in | Must be designed and kept |
| Fit to your process | Licence: configurable | Exact |
| Key-person risk | Licence: lower | Higher |
Frequently asked questions
Is building LP reporting cheaper?
Sometimes upfront, rarely over time. Maintenance, staff turnover and new requirements usually dominate the cost.
When does building make sense?
When reporting is a real source of advantage and you already run an engineering team that can own it long term.
Can we buy and still customise?
Yes. Most funds license the reporting layer and customise templates, commentary and investor views.
What should we measure in the comparison?
Lifetime cost including people, time to the first report, upkeep effort and how easily figures trace back to source.
How long does it take to switch?
It depends on data quality. Start with one fund and one quarter to test before moving everything.
