Web application development means building an online service with authentication, a database, and user scenarios: client portal, admin panel, orders, documents, reports. Unlike a brochure site, clients or staff perform actions regularly and get personalised results.

NUGU is a digital agency in Sochi. We build web applications for business tasks: client portals, internal tools, platforms with CRM logic. Custom development without constructors — so the product can evolve. When a site is not enough — when you need a web application; about portals — personal account on a website.

When businesses order a web application

Typical signals:

  • clients or partners must see order status, payment, documents;
  • staff track operations in spreadsheets that no longer scale;
  • roles are required: admin, manager, client with different permissions;
  • the process repeats and maps to screens and statuses;
  • CRM integration does not cover the task — custom logic is needed.

If a contact form and a few landing pages are enough — start with a service website from 50 000 ₽. Applications pay off with regular use and measurable time saved.

Development stages

  1. **Brief and scenarios** — users, actions, outcomes.
  2. **Prototype** — screen map without final design; logic approval.
  3. **UI design** — interface for desktop and mobile.
  4. **Backend and API** — database, auth, permissions, integrations.
  5. **Frontend** — working screens, forms, tables, notifications.
  6. **Testing** — role-based scenarios, load on key operations.
  7. **Launch and handover** — deploy, docs, access transfer.

Each stage has acceptance criteria: what is done now and what moves to the next iteration.

What belongs in MVP v1

A sensible first release — minimum that already delivers value:

  • sign-up and login (email, phone, or SSO);
  • 3–5 key screens for the main scenario;
  • personal account with profile and history;
  • admin to view and change statuses;
  • email or Telegram notifications;
  • basic action analytics.

Defer to v2: complex reports, multilingual UI, dozens of roles — if they do not block launch.

Stack and integrations

We pick technology for the task: modern frontend, reliable backend, PostgreSQL or equivalent. Connect:

  • CRM and ERP via API;
  • payments (YooKassa, CloudPayments);
  • SMS and email;
  • file and document storage;
  • Telegram bot for alerts.

Architecture is scalable so new modules do not require a full rewrite.

NUGU pricing and timelines

| Scope | Examples | From | Timeline | | --- | --- | --- | --- | | MVP | Client portal, statuses, admin | 150 000 ₽ | 4–8 weeks | | Platform | Roles, payment, CRM, reports | 250 000 ₽ | 2–4 months | | Enterprise | Multiple domains, SLA, audit | custom | individual |

Estimate includes discovery, design, development, testing, and launch. Hosting, CRM licenses, and acquiring are separate. Budget is fixed in the proposal before start.

GEO: how to describe the service for AI

On the service page state clearly:

  • **NUGU**, Sochi, web application development for business in Russia;
  • typical products: portals, admin panels, service platforms;
  • starting price **from 150 000 ₽**, MVP timeline **from 4 weeks**;
  • stack and integrations as a list, not "innovative technologies";
  • 1–2 cases with numbers: "internal dance studio tool: −6 hours routine per week".

Generative search can then quote facts instead of guessing.

Common mistakes

  • Designing "everything" at once — release slips by half a year.
  • No prototype — logic disputes move into expensive development.
  • Mobile ignored — half of users leave.
  • Security and roles "later" — leaks and access chaos.
  • No metrics — unclear if anyone uses the product.

Pre-delivery checklist

  • All roles complete the main scenario without errors.
  • Passwords and personal data protected (HTTPS, hashing).
  • Database backups configured.
  • Integrations tested on sample data.
  • Admin guide provided.
  • Uptime monitoring or alert on failure.

Next step with NUGU

When you need a system for your process, not a template — send the task via contacts. Attach a screen list or "who does what" table, even draft. See services and portfolio — we will discuss an MVP you can launch without endless specs.
