NetDocuments Workflow Automation: Build vs Buy the Right Module

"We already pay for NetDocuments. Why would I pay for something else just to get one workflow working?"

I hear a version of that from almost every managing partner or ops director who calls us after sitting through a NetDocuments renewal pitch. The rep is pushing PatternBuilder, or ndMAX, or both, and the pitch sounds reasonable until someone asks what happens when the firm's actual workflow doesn't match the demo. That question is the whole post.

NetDocuments is a document management system, not a decision engine. It stores, versions, and secures documents better than almost anything else on the market. It does not, on its own, decide whether a new matter creates a conflict, whether an incoming email needs to become a matter at all, or whether a document buried three folders deep from 2019 is relevant to what a partner is reading today. Those are judgment calls, and until recently the only way to make them was to have a person read the material.

This post is about the layer that sits on top of NetDocuments to make those calls faster, not the DMS itself. I'll use conflict checks as the running example because it's the sharpest illustration of where the line between "buy another module" and "build the specific thing" actually falls. But the argument applies to matter intake, document classification, and anything else where a firm's workflow has a shape NetDocuments' packaged tools weren't built to fit.

What PatternBuilder and ndMAX actually do

PatternBuilder is NetDocuments' no-code workflow builder. You drag together forms, approval steps, and document templates without writing code, and it plugs into the DMS you already have. It's genuinely useful for structured, repeatable processes: engagement letter generation, standard intake forms, routing a document for sign-off. If your workflow is "collect these five fields, generate this template, route to these three people," PatternBuilder does that well and you don't need us.

ndMAX is the AI layer NetDocuments has been building on top of its search index. Ask it a question about a document or a matter and it answers from what's indexed, similar to what Microsoft Copilot does inside Office. It's a real capability, and for "summarize this document" or "find documents about X," it's a reasonable first stop.

Here's the part neither NetDocuments' own PatternBuilder page nor the ndMAX marketing says out loud: "no-code" describes the interface, not the workforce required. Someone still has to map the firm's actual process onto PatternBuilder's form-and-approval model, and that person needs to understand both the workflow and the tool well enough to know where the two don't line up. I've watched firms buy the module, hand it to whoever's free that quarter, and end up with a workflow that technically runs but nobody trusts, because it was built by someone translating the firm's process into the vendor's abstraction instead of the other way around. I've written before about why iManage workflow automation still falls short for the same reason, and NetDocuments' packaged tools have the identical blind spot.

Where the packaged tools stop: conflict checks

Take conflict checks as the concrete case. Most firms run this as a name-matching search against a database at new-matter intake, and then a person reviews whatever comes back to decide if it's a real conflict or a coincidence. Neither PatternBuilder nor ndMAX changes this in any meaningful way. PatternBuilder can route the intake form to the right reviewer. ndMAX can answer "does this document mention the Acme Corp matter" if you ask it directly. Neither one reads the substance of every historical matter document against a new intake and tells you what actually matches.

That gap is real because a genuine conflict is often not a name match at all. It's a related entity, a parent company, a passage buried in a document from a matter closed three years ago, referencing a person who never appears in the caption. No name search surfaces that, and PatternBuilder was never built to.

What we build instead is an AI layer that runs on top of the DMS rather than beside it: pull the incoming matter details, search the firm's existing matter documents for substance rather than names alone, have Claude (Anthropic's AI model) read for potential conflicts including related entities, surface the specific passage that triggered each flag, and hand the final call to conflicts counsel. The conflicts process, the ethical wall procedures, the partner sign-off all stay exactly where they are. What changes is the time a lawyer spends reading through documents between the name-match hit and knowing whether it's real.

Do the math before you buy anything

I won't hand you a made-up percentage here, because I don't have a verified benchmark for this specific workflow and I'm not going to invent one. I've gone deeper on the ROI and risk math for conflict-check automation in a separate post, but the short version is this: take the number of new-matter intakes per month, multiply by the hours a lawyer or paralegal spends manually reading through prior matter documents on every flagged name match, and multiply that by their billable rate. That's the number PatternBuilder and ndMAX don't touch, because neither one reads document substance against a new intake on its own. If that number is small for your firm, buying another module is the right call. If it's not, you're paying attorney billable rates to do reading a workflow could do first.

Security, and what mid-size firms are really afraid of

The apprehension I hear most from mid-market firms, the ones with 20 to 150 lawyers who already run NetDocuments and have an IT team but not a dedicated AI function, isn't "will this work." It's "will this break what we already have, and who's responsible when it does."

A workflow built on top of NetDocuments should never require moving documents out of NetDocuments. It reads through the API, respects the same ethical walls and access restrictions your firm already enforces, and every AI action should leave an audit trail your compliance team can pull. If a vendor's answer to "where does our document data go" is vague, that's the wrong vendor, custom-built or packaged. The workflow doesn't replace iManage or NetDocuments as the system of record. It's a reader that sits alongside the record, not a second copy of it.

The other mistake I've seen firms make, independent of build-vs-buy, is treating every AI-flagged conflict with equal weight. If the system flags everything at the same urgency, reviewers learn to ignore the flags within a month, which defeats the entire point. A workflow worth building calibrates confidence over time, using real outcomes, not a fixed threshold set on day one.

When to buy the module, and when to build

Buy PatternBuilder or ndMAX when the workflow is genuinely standard: intake forms, templated documents, routing that follows an org chart, answering questions about a single document you already have open. Those are commodity problems and NetDocuments' own tools solve them well. Paying us to rebuild that would be a waste of your money, and I'd tell you so on a call.

Build something custom when the workflow depends on reading and reasoning across a large body of existing documents to catch something a name or keyword search would miss, and when getting it wrong has a real cost, whether that's a missed conflict, a misclassified privileged document, or hours of billable time spent on manual review that a firm's own partners would rather spend on client work. Conflict checks are the clearest version of this, but the same logic applies to due diligence document review and matter intake classification, anywhere the firm's actual process doesn't match a vendor's generic template. I laid out the broader version of this decision in build vs buy for law firm AI if you want the full framework beyond NetDocuments specifically.

If you're not sure which bucket your workflow falls into, that's a fifteen-minute conversation, not a purchase decision. Most firms know within the first five minutes of describing the workflow which side of the line they're on.

Frequently asked questions

Is PatternBuilder enough for a NetDocuments workflow automation project?

For structured, repeatable processes like standard intake forms or approval routing, yes, and you should use it rather than pay for something custom. It stops being enough the moment the workflow needs to reason over the substance of existing documents rather than move a form through a sequence of steps, which is exactly where conflict checks and due diligence review live.

What does ndMAX actually add that PatternBuilder doesn't?

ndMAX answers questions from what's already indexed in NetDocuments, closer to a search assistant than a workflow engine. It's useful for "summarize this document" or "find documents mentioning X" on demand. It doesn't run a standing process that reads every new matter against a firm's full document history and flags what matches, which is a different job than answering a question when asked.

Does a custom workflow replace NetDocuments or iManage?

No, and it shouldn't try to. NetDocuments and iManage stay the system of record, with the same security model, ethical walls, and access controls the firm already runs. A custom workflow reads through that system rather than around it, and any vendor suggesting you move documents elsewhere to make their AI work is asking you to weaken the security model you already paid for.

How long does it actually take to stand up something like the conflict-check workflow?

A realistic rollout runs in phases over roughly a month: validate the workflow against historical matters where the outcome is already known, route new flags to conflicts counsel alongside the existing process rather than replacing it, then spend the following weeks calibrating confidence thresholds against real results. Firms that skip the validation phase are the ones who end up distrusting the tool within the first month.
