In short

Techthaastu Private Limited is a web portal development company based in New Delhi, India. We design and build secure, role-based web portals — including client self-service, vendor, employee, B2B, DSC management, GST filing and e-tender portals — and integrate them with Tally, GST/GSP, payment gateways, CRMs and ERPs. We work mainly with CA firms, legal practices, insurers and compliance-driven enterprises, and ship every project on a fixed written quote with a post-launch support plan.

The basics

What is a web portal — and how is it different from a website?

A website shows mostly the same public pages to everyone. A web portal signs each user in and shows a personalised, role-based view of data drawn from your back-end systems — invoices, documents, tickets, filings or orders.

Put simply: a website informs; a portal lets a logged-in user transact and self-serve. That single difference is why portals reduce email back-and-forth, manual data entry and "where is my document?" calls.

Many real projects blend a portal and a web app — a logged-in dashboard that is both personalised and task-driven. We scope which one you actually need before quoting.

What we build

Types of web portals we develop

Each portal is built around real user roles and the systems your team already uses.

Client / Customer Self-Service Portal

Let clients log in to view invoices, share documents, raise tickets and track status — cutting repetitive email and phone follow-ups.

Vendor / Supplier Portal

Onboard vendors, exchange POs and invoices, track approvals and payments in one place, with a full audit trail.

Employee Intranet Portal

A single internal hub for leave, payslips, documents, announcements and approvals — with role-based access for HR, managers and staff.

DSC Management Portal

Track Digital Signature Certificates, tokens, expiries and renewals, with eMudhra/DSC workflows — built for CA and compliance teams handling many clients.

GST Filing Portal

Manage client GSTINs, returns, reconciliation and deadlines in one dashboard, with GSTN/GSP integration and reminders.

e-Tender Management Portal

Publish tenders, collect bids securely, manage documents and timelines, and keep a transparent record for every participant.

B2B / Dealer Portal

Give partners and dealers a portal to place orders, check pricing and stock, and view statements — connected to your ERP.

Insurance / BFSI Portal

Policy, claims and document portals for insurers and brokers, with secure access for customers, agents and back-office teams.

Custom Enterprise Portal

Have a workflow that doesn't fit a template? We design custom multi-role portals around your exact process and integrations.

Under the hood

How we build secure portal architecture

Data flows from your users through an authenticated API layer to your databases and connected systems — with security applied at every step.

LayerWhat we implementWhy it matters
AuthenticationJWT / OAuth 2.0, optional multi-factor authentication (MFA), session controlsOnly the right people get in, with enterprise-grade login security.
Access controlRole-based access control (RBAC), document-level permissions, audit logsEach role sees only its own data; every action is traceable.
Data & APIsRESTful APIs / GraphQL, validation, rate limitingFront-end and back-end stay in sync, safely and predictably.
Data protectionTLS in transit, encryption at rest, scheduled backupsSensitive financial and client data stays protected.
IntegrationsTally, GSTN/GSP, DSC / eMudhra, Razorpay / PayU, CRMs & ERPsYour portal talks to the tools you already run — no manual re-entry.
HostingAWS / managed cloud, monitoring, SSL, loggingThe portal stays online, observable and recoverable.
Where we're strongest

Industries we build portals for

Our edge is compliance-heavy work. We already build practice-management systems, client portals and automation tools for professional-services firms — so we understand documents, deadlines, roles and audit trails.

Discuss your industry
  • CA & accounting firms — client, DSC and GST portals
  • Legal practices — case, document & client portals
  • Insurance & BFSI — policy, claims & agent portals
  • Government / PSU — e-tender & citizen portals
  • Healthcare & education — patient & student portals
  • Manufacturing & logistics — vendor & dealer portals

Why this matters for compliance teams: DSC, GST and tender portals carry strict access, deadline and audit requirements. We've built for these constraints, so you're not paying us to learn them on your project.

Our process

How we develop your web portal

Six clear phases, with a usable first release early — not a year-long black box.

1

Discovery & scope

We map your roles, data, integrations and must-have features, then write a fixed scope and quote.

2

UX & UI design

We design clear, role-based screens and get your sign-off before a line of production code.

3

Development

We build the portal and APIs in phases, with regular demos so you see progress every week.

4

Security & QA

We test access control, integrations and edge cases, and harden the portal before launch.

5

Launch & migration

We deploy to your cloud, migrate data carefully, and train your team on day-one use.

6

Support & AMC

Patches, backups, monitoring and enhancements keep the portal secure and current after go-live.

WHAT OUR CLIENT SAY

FAQs

Frequently Asked Questions

A website mostly shows the same public information to every visitor. A web portal authenticates each user and shows personalised, role-based data — invoices, documents, tickets or filings — pulled from back-end systems. In short, a website informs; a portal lets a logged-in user transact and self-serve.

We use role-based access control, JWT or OAuth 2.0 authentication, optional multi-factor authentication, encrypted data in transit (TLS) and at rest, audit logs, and least-privilege database roles. For compliance clients we also add document-level permissions and activity trails.

Yes. We build API integrations with Tally, GSTN/GSP providers, DSC and eMudhra workflows, payment gateways like Razorpay and PayU, and common CRMs and ERPs. Where no API exists, we use secure file or RPA-based syncing so data flows without manual re-entry.

Yes. Every portal ships with a post-launch support and maintenance plan (AMC) covering security patches, backups, monitoring, bug fixes and small enhancements, so the portal stays secure and current after go-live.

A focused client or vendor portal usually takes about 6 to 10 weeks. Larger multi-role platforms with several integrations take 3 to 5 months. We work in phases, so you get a usable first release early and add modules after launch.

Cost depends on the number of user roles, the integrations required, data volume and security needs, and whether you need a mobile app alongside the portal. We scope each build and share a fixed written quote before work starts, with no hidden charges.
