Customer Portal Development Legal · Customer Portal Development # Law Firm Client Portal Development Privileged messaging, trust account visibility, and matter status in one place, so case updates stop living in an email thread.

A client portal fixes the access and organization problem, but only if it's built around what a legal client actually needs to see, not a generic support-ticket layout borrowed from a different industry. Money is the other place a generic portal falls short. A client funding a matter through a retainer expects to see that trust account balance and how it's being drawn down, which is a different kind of transparency than a support portal's invoice history, since trust funds are the client's own money held under a state bar's IOLTA rules, not the firm's revenue. Billing detail matters just as much: a client disputing a bill wants to see the actual time entries behind a charge, not just a total that reads as a black box. We build client portals around privileged, access-controlled messaging in place of email, trust account and retainer balance visibility tied to the firm's actual trust accounting, secure document and evidence upload with a preserved record of who uploaded what and when, and matter status pulled from the firm's practice management system rather than manually updated by an assistant. Requirements ## What legal teams need from it - ### Privileged messaging that replaces email for case communication Case-related messages need to live in an access-controlled channel scoped to the matter, rather than an email inbox with no built-in control over forwarding or long-term access once a matter closes or staff changes. - ### Trust account and retainer balance transparency A client funding a matter through a retainer is looking at their own money held under the state bar's IOLTA rules, and the portal needs to reflect that balance and its draw-down accurately, drawn directly from the firm's trust accounting records. - ### Detailed, disputable billing information A client questioning a bill needs to see the specific time entries and descriptions behind a charge, not just a total, since a black-box invoice is what generates a billing dispute in the first place. - ### Secure evidence and document upload with a preserved record Clients sharing evidence or documents for an active matter need a secure upload path that records who uploaded what and when, which matters if a document's chain of custody or timing becomes relevant to the matter itself. - ### A unified view for clients with more than one open matter A client with two or three matters open at the same firm needs one account that shows all of them, rather than separate logins or a single matter view that has no way to distinguish which case a message or document belongs to. Scope ## Features we build - ### Privileged client messaging Case communication happens in an access-controlled channel scoped to the specific matter, replacing email threads that offer no real control over who eventually sees a forwarded message. - ### Trust account and retainer balance visibility Clients see their retainer balance and how it's being drawn down, reflecting the firm's actual trust accounting rather than a periodic manual update from a paralegal. - ### Matter status tracking Status pulls from the firm's practice management system, giving clients an accurate picture of where their matter stands without needing to email an associate for an update. - ### Detailed invoice and time-entry visibility Invoices break down into the specific time entries and descriptions behind each charge, giving a client a way to review a bill in detail rather than disputing a total they can't see the basis for. - ### Secure document and evidence upload Clients upload documents or evidence for their matter through a secure channel that records who uploaded what and when, preserving a clear record if that timing or origin becomes relevant later. - ### E-signature for engagement letters and matter documents Engagement letters and other matter documents route for signature directly through the portal, with a full audit trail kept as part of the matter record. - ### Multi-matter client dashboard Clients with more than one open matter at the firm see all of them in a single account, with messages, documents, and billing clearly separated by matter. - ### Matter-scoped access permissions Portal access mirrors the same matter-level restrictions the firm's document management system already enforces, so a client only ever sees the matters they're actually a party to. ## Compliance and standards - attorney-client privilege and confidentiality handling - state bar IOLTA trust accounting rules - state bar rules on client file access ## Systems it connects to - Clio - iManage - NetDocuments - DocuSign - LawPay - Microsoft 365 Build vs buy ## When to build it and when to buy it Clio for Clients and MyCase's client portal cover standard matter status, messaging, and document sharing well for a firm already running one of those practice management platforms, and that bundled option is usually faster to roll out than a custom build. Custom development earns its cost when clients need trust account and time-entry transparency beyond what those bundled portals expose, when the portal needs to sit inside the firm's own branded site rather than a vendor login domain, or when a multi-matter view has to unify data across a DMS the practice management tool doesn't read natively. Technology ## Typical stack - [Next.js](https://cyanorbit.com/technologies/nextjs) - [Node.js](https://cyanorbit.com/technologies/nodejs) - [PostgreSQL](https://cyanorbit.com/technologies/postgresql) - [TypeScript](https://cyanorbit.com/technologies/typescript) FAQ ## Frequently asked questions Why use a client portal instead of email for case communication? Email offers no real control once a message is sent, it can be forwarded, left in an inbox indefinitely, or accessed on a shared device, while a portal keeps privileged communication in an access-controlled channel scoped specifically to that matter, which is a meaningfully different confidentiality posture for case content. Can clients see their retainer or trust account balance in the portal? Yes, the portal reflects the client's actual trust account balance and how it's being drawn down, pulled from the firm's real trust accounting rather than an estimate, since that money belongs to the client and is held under the state bar's IOLTA rules. Can clients securely upload evidence or documents for their case? Yes, uploads go through a secure channel that records who uploaded a document and when, which preserves a clear record that can matter if the document's timing or origin becomes relevant to the case later. Can clients see a detailed breakdown of billed time, not just a total invoice? Yes, invoices in the portal break down into the specific time entries and descriptions behind each charge, giving a client a way to review what generated a bill rather than disputing a total with no visible basis. Can a client with more than one matter at the firm see all of them in one account? Yes, a client with several open matters sees all of them in a single account, with messages, documents, and billing clearly separated by matter so nothing from one case gets confused with another. Should we use Clio for Clients or build a custom law firm portal? Clio for Clients and MyCase's portal cover standard status, messaging, and document sharing well for a firm already on one of those platforms. Build custom when clients need trust account or time-entry transparency those bundled portals don't expose, or when the portal needs to live inside the firm's own branded site.
