Document Sharing & E-Signature
Upload, version and sign documents without a single email attachment.
Custom client portals built around how your clients actually work with you — secure logins, document sharing, project visibility and billing, in one place instead of scattered emails.
In short: client portal development is the process of building a secure, login-protected space where your clients can check project status, share and sign documents, view invoices and message your team — replacing scattered email threads with one organized, self-service view.
Shunyastra builds custom client portals designed around what your clients actually need to see and do — not a generic file-sharing tool bolted onto your website.
A design agency sharing proofs and a distributor sharing order status don't need the same portal. Here's how we match the build to what your clients actually need to see.
Secure, organized document exchange with version control, approvals and e-signature — no more "final_v3" attachments.
Best For: Agencies & ConsultanciesLive project timelines, milestones and deliverables so clients always know where things stand without asking.
Best For: Service & Project-Based TeamsInvoice history, payment status and online payment collection built directly into the client's own dashboard.
Best For: Retainer & Subscription BillingOrder history, reorder tools and account-level reporting for clients who transact with you repeatedly.
Best For: Distributors & B2B SuppliersTicketing, messaging and knowledge base access built into a single client-facing support hub.
Best For: Support-Heavy BusinessesRole-based access across departments and client accounts, unified into one system for large service providers.
Best For: Enterprises & Multi-Account FirmsFrom the first client-journey interview to the day your first client logs in, here's what's included when you work with Shunyastra on a portal build.
Every client gets a private login that only shows their own files, projects and invoices — with full activity logging of every action taken inside the portal.

Live status updates so clients stop emailing to ask "where are we at?"
Invoice history and secure payment collection built into the client view.
Threaded, on-record conversations tied to the right project or invoice.
Portal data synced with your CRM, ERP or internal databases automatically.
Bug fixes, monitoring and new modules added as your client base grows.
That makes trust non-negotiable. Every portal we build separates client data at the account level, encrypts files in transit and at rest, and logs every view, download and approval — so if a client ever asks "who saw this," you have a real answer, not a guess.
A structured, six-stage process keeps access rules, data structure and integrations predictable — no rebuilding the portal every time a new client type gets added.
We map what your clients need to see and do at each stage — from onboarding to ongoing delivery and billing.
We design the account hierarchy, permission structure and data isolation rules before development begins.
Portal screens are wireframed and reviewed against real client scenarios, not just internal assumptions.
Development runs in two-week sprints with continuous demos, so you see working modules early and often.
Every account's data boundaries are tested to confirm no client can see another client's information.
Client onboarding support and a maintenance plan for adding new modules as your services evolve.
The right modules, access rules and integrations depend on how your clients actually engage with you. Here's what we typically prioritize by industry.
Document sharing, sign-off workflows and project timelines built for clients who need visibility without status calls.
Case and document portals with strict access separation, e-signature and full retention-ready audit trails.
Project milestones, site photos, permits and payment schedules shared with clients as work actually progresses.
Patient-facing portals for records access, appointment status and billing, built with strict data privacy controls.
Order history, reorder tools and account-level reporting built for repeat B2B buyers managing multiple accounts.
Client onboarding checklists, performance reporting and billing built into a single branded client dashboard.
Email and shared drives feel free, until a client asks for a file you sent four months ago. Here's where a dedicated portal tends to make a real difference.
We pick the stack based on what your portal actually needs to stay fast, secure and maintainable long after launch.
A portal is only useful if clients log in instead of emailing you anyway. Here's what that looks like when you work with us.
Talk To Our TeamWe map what your clients need to see and do at each stage before designing a single screen, so the portal fits real use instead of forcing new habits.
Code that another developer can pick up later, without needing to reverse-engineer decisions no one wrote down.
Account-level data isolation, encryption and audit logging are part of the build from day one, not an afterthought.
Maintenance plans covering bug fixes, monitoring and new modules, so the portal keeps pace as your client base grows.
A client portal is a secure, login-protected website or web app where your clients can view project status, share and sign documents, check invoices, and message your team — instead of relying on email threads and shared drives. It gives each client a private, self-service view into work you're doing for them.
Email and shared drives scatter information across threads and folders, with no reliable way to control who sees what or track what's been read or approved. A client portal centralizes files, approvals, status updates and billing behind secure, role-based logins, with a clear audit trail of every action.
Cost depends on the number of modules, how many user roles are involved, and how many systems the portal needs to connect to. A focused portal for document sharing and status updates costs less than one with billing, e-signature and CRM integration. We scope every project individually and provide a fixed quote after understanding your requirements.
A focused client portal with document sharing and status tracking typically takes 6 to 10 weeks. Portals with billing, e-signature, messaging and CRM or ERP integration usually take 10 to 16 weeks, and large multi-role enterprise portals can take longer depending on scope.
Yes. We integrate secure payment gateways into client portals so clients can view invoices, make payments and download receipts without leaving the portal.
Every client portal we build uses encrypted data storage, role-based access so clients only see their own records, secure authentication, and full activity logging, so you always know who accessed or changed what.
Yes. We offer ongoing maintenance plans covering bug fixes, security monitoring and new feature development, so the portal keeps working reliably as your client base and services grow.
