Hire SaaS Developer for Law Firms
Senior, direct, no layers

A law firms firm that has solved its own operational problem well sometimes discovers the solution is worth selling: a way of running intake, conflict checks, matter management, documents, billing and client updates that other firms would pay to use. Turning an internal tool into a product other firms rely on is a different job from building the tool, and most of the difference is invisible until launch.

A SaaS developer builds multi-tenant software products: one codebase serving many customers, each with their own data, settings and billing, plus the onboarding, subscription handling and support surfaces a product needs. The work covers the product itself, not a single firm's internal system, and every decision is made for dozens or hundreds of tenants rather than one team.

The warning that comes with this engagement is about sequencing. A product needs a first ten customers and a reason they stay before it needs scale, and building for scale before finding those customers is the most common way to burn the budget. The build order follows customers, not ambition.

If the product idea has its first customers in sight, talk through the product idea first and we will define what the smallest sellable version must do.

The build starts with the tenant boundary at matter level, because one firm seeing another's clients or advice ends the product and the firm's reputation with it. Clients, matters, documents, deadlines and walls are modelled per tenant from the first table, and tests deliberately try to read across tenants, including through opposing matters and shared client names.

Launch is proven on a real matter lifecycle, not a demo file. A small group of real firms runs live matters on subscription, from intake and conflict check through documents and deadlines to billing, and billing, folder setup and support are fixed from what those firms actually hit before the product opens wider. Code, billing setup and hosting stay in the business's own accounts.

When the legal platform works, a managing partner sees it in deadline control: matters carry their deadlines, documents, conflict-check notes and client communications in order, so a filing date is chased weeks ahead instead of discovered the day before, and client portals show only that client's matters. A new firm can sign up, add its matter types and deadline rules, set its document folders and confidentiality walls and run its first matter without waiting on the platform owner, while each firm's clients and advice stay inside its own tenant. Growth comes firm by firm, with billing, onboarding and support proven on real matters rather than promised in a demo file.
