Custom AI Builds vs SaaS Tools for RIAs: When to Build

An advisory firm does not reach an automatic custom-build threshold at ten or fifteen advisors. A small firm can have a difficult integration problem. A large firm can use standard software successfully. Decide from the work that needs to happen and the resources available to maintain it.

Define one workflow

Write down the trigger, permitted inputs, required output, approving person and system of record. Then identify the problem with the current process.

For example, a fictional firm wants a draft annual-review agenda from approved CRM notes and planning records. The required output includes the source for each agenda item and an unresolved-questions list. It must not recommend trades or send a client message automatically.

That is a testable scope. "Build an AI platform for the firm" is not enough to compare proposals.

Compare three options

Use the same fictional test records for every option. Include incomplete records, stale notes, conflicting values and a user who should not see a particular record.

A vendor demonstration does not establish that your account configuration and data access will work the same way.

Check the data path

List where each record goes: source application, connector, model service, logs, output store and backups. Review access, retention, deletion, incident procedures and contractual terms for the specific services and configurations.

A SOC 2 report or encryption feature does not by itself establish compliance for the firm's workflow. Buying software does not remove the firm's oversight responsibilities. The SEC's Regulation S-P amendments are a relevant primary source for covered institutions' safeguarding and related obligations. Have the firm's reviewer determine the applicable requirements.

Local hosting is not an automatic exemption either. Permissions, copied records, support access and backups still need examination.

Compare written total costs

Collect quotes for a defined period and expected usage. Include:

• Implementation and configuration.
• Subscriptions, minimum commitments and usage charges.
• Integration work and data cleanup.
• Internal review, training and support.
• Monitoring, security updates and model or API changes.
• Export, migration and eventual retirement.

Separate one-time costs from recurring costs. Ask which assumptions change the quote. Seat prices need not scale linearly, and custom maintenance is not a fixed percentage you can safely invent.

Do not count every minute of draft generation as recovered capacity. Include checking, corrections and exceptions before estimating any benefit.

A practical acceptance record

For the fictional agenda workflow, a reviewer should be able to answer:

1. Does every agenda item identify an actual source record?
2. Are missing facts left unresolved?
3. Does the output stay inside the user's record permissions?
4. Can a reviewer correct the draft before it reaches a client?
5. Can the firm recover when a source or model service is unavailable?
6. Can the firm export the records it needs if the relationship ends?

Record the result and the observed failure, not just a pass percentage. A permission leak cannot be averaged away by many correct agenda items.

Choose a limited next step

Use an existing product when it meets the actual requirements at an acceptable total cost and ownership burden. Consider a custom component when an important requirement remains unmet and someone can maintain it.

A hybrid arrangement can be appropriate, but it introduces another interface to support. Do not describe it as inherently cheaper or more distinctive.

Agree on a narrow pilot, a stopping condition and a maintenance owner before expanding. This also gives a builder a concrete scope to quote. The decision is whether the option meets the firm's requirements, not whether AI adoption sounds strategically urgent.
