Legal and professional services software development

Legal and professional services software development for law firms, legal departments, accounting and tax firms, consultancies and legal tech companies: practice and matter management, document automation, contract lifecycle management, AI contract review and legal research, client portals, time and billing, e-signature and secure document exchange, with dedicated legal tech developers for your team or a product delivered end to end.

What we build for legal and professional services

  • Practice and matter management

    Matters, clients, deadlines, conflict checks and documents in one system, built for your practice or integrated with Clio, iManage or NetDocuments.

  • Document automation

    Contracts, letters and filings generated from templates and questionnaires, with clause libraries that lawyers maintain themselves.

  • Contract lifecycle management

    Requests, drafting, negotiation, approval, signature and obligation tracking, integrated with Ironclad or DocuSign CLM or built for your process.

  • AI for legal work

    Contract review against your playbook, clause extraction, due diligence summaries and research assistants that cite their sources, with a lawyer reviewing every output.

  • Client portals

    Secure portals where clients share documents, sign, follow their matter and pay invoices.

  • Time, billing and practice automation

    Time capture, billing rules, LEDES e-billing, and workflow automation for accounting and tax practices.

Hire legal tech developers

  • Dedicated legal tech developers

    Legal tech developers who join your team full time, work in your tools and process, and report to your lead. You interview them; we carry the Ukrainian contract, payroll, invoicing and leave.

  • Legal software development projects

    A defined piece of legal software development with a scope, a fixed plan and a named lead on our side who owns the result and reports progress in your channels.

  • Ongoing legal software development

    Legal software development as a continuing service: the same people every month, a backlog you prioritise, and hours you can see in our portal and on the invoice.

The dedicated team page explains how specialists join your team, and the outsourcing page covers project delivery, take-overs and how we charge.

Confidentiality built in

Legal and professional work is confidential by default, so documents are encrypted, access follows matters and ethical walls, every view and download is logged, and client data stays in your own tenant.

AI is used where a professional checks the result: outputs cite the clause or source they rest on, client documents are not used to train models, and each tool is tested on your own documents before it touches a live matter.

Questions about legal software development

Can you integrate with Clio, iManage or NetDocuments?

Yes, through their APIs, so matters, documents and time flow between the platform and your portals, automation and billing without re-keying.

How do you keep client documents confidential when using AI?

Through business API terms that exclude training on your data, or models hosted in your own cloud, with documents retrieved only for users who may see them and every request logged.

How quickly can legal tech developers start?

When the right legal tech developer is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.

How do we hire legal tech developers through BigTree108?

Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.

Who owns the work they produce?

You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.
