Custom software that replaces the spreadsheets and duct tape, shipped in quarters, not years. Designed and shipped for law firms, not generic templates with law firms swapped in.
Most law firms are operating on sites or software stacks built three to five years ago for a different version of the buyer. New-matter intake runs on phone calls and email, so after-hours inquiries go unanswered and signed-case revenue leaks at the door. The infrastructure decisions that compound are the ones made with the operator in the room, not the ones made in a vacuum.
Inparlor's Custom Software Development engagement for law firms reflects that. We build custom software for the work no off-the-shelf tool fits: operations platforms, customer portals, internal tools, and multi-tenant systems that talk to your Stripe, Salesforce, or HubSpot data. The deliverables below are scoped against the unit economics, signed pi case value (avg) of $25,000-$80,000.
Where most agencies treat law firms as another vertical to learn on, we treat the vertical as the starting point. Case files, deadlines, and client communication live across disconnected tools, so status updates require digging through inboxes. We will tell you on the first call which of those constraints is binding and which is solvable inside the engagement.

Custom Software proposal turnaround
Two weeks, scoped and paid. We map the workflow, talk to operators, and write a wireframe pack you can use even if you do not hire us. The bid that follows is a number, not a range.
Clerk or WorkOS for auth. Stripe for billing. Role-based access control from the first sprint. These are solved problems and we do not re-solve them every engagement.
Boring works. Postgres covers 95% of operator workloads. The migration to something exotic is real but cheap if you ever need it, and most teams never do.
Sentry, Axiom, and a feature-flag layer ship with the first sprint. You cannot debug what you cannot see, and we will not hand off code we cannot diagnose.
