SharePoint Solution Development: A Step-by-Step Guide for Businesses

Key takeaways

• Start with the business problem, not the platform. Pick three to five measurable goals first, such as faster approvals or one governed home for policies. Every later decision is judged against them.

• Structure comes before design. Information architecture, metadata and governance decide whether SharePoint feels organised or chaotic, so plan them before building anything.

• Configure first, automate with low-code, write code last. Built-in features and Power Apps cover a lot. Use SPFx and .NET only where they add real value.

• SharePoint Online is the practical default. SharePoint Server 2016 and 2019 lost Microsoft support in July 2026, so teams on those versions should plan an upgrade or a move to the cloud.

• Budget two things: licences and the build. Microsoft 365 licensing starts around USD 7(₹670)per user per month. (₹2.9 lakh) for a basic team site to US$100,000+ (₹96 lakh+) for an enterprise portal with integrations.

• Timelines run from 3 weeks to 9 months. Scope, integrations and the quality of your existing content are the biggest drivers.

• Test permissions and security before launch. One sharing mistake can expose sensitive files, so give testing real time.

• Adoption decides the return. Plan training, department champions and a support budget of roughly 15 to 20% of build cost per year.

• Tidy your content before adding AI. Copilot and custom AI tools are only as useful as the documents and permissions behind them.

What is SharePoint solution development?

SharePoint is Microsoft's platform for intranets, team sites, document management and business workflows. Out of the box it is a capable file and collaboration tool. Solution development is what turns it into your system: a branded intranet people actually open, a document library with the right approvals, a leave-request flow that replaces email chains, a portal that pulls live data from your ERP.

The work usually combines four layers:

• Configuration: sites, hubs, libraries, content types, metadata and permissions.

• Custom development: SharePoint Framework (SPFx) web parts, .NET back ends, Azure Functions and APIs.

• Low-code automation: Power Apps and Power Automate for forms and approvals.

• Integration and migration: connecting ERP, CRM, HRMS and moving content from legacy systems.

One point worth knowing before you plan: SharePoint comes in two flavours. SharePoint Online lives inside Microsoft 365 and is where Microsoft is investing. SharePoint Server runs on your own infrastructure. Microsoft's support for SharePoint Server 2016 and 2019 ended in July 2026, so teams still on those versions should be planning an upgrade or a move to the cloud now.

Nextwebi has delivered SharePoint work across SharePoint 2007, 2013, 2016, 2019 and SharePoint Online. Explore our Microsoft SharePoint customization and development services or the SharePoint platform page.

Why businesses invest in custom SharePoint solutions

• One source of truth. Policies, contracts and project files live in one governed place, not scattered across inboxes and shared drives.

• Faster approvals. Workflows route requests automatically and leave an audit trail.

• Better internal communication. A proper intranet gives news, directories and tools a single front door.

• Security you can prove. Role-based access, versioning, retention and sensitivity labels support audits and compliance.

• Lower tool sprawl. If you already pay for Microsoft 365, SharePoint is included in your licence, so you build on what you own.

• Room to grow. Add integrations, dashboards and AI features later without replatforming.

Before you build: out of the box, customised or fully custom?

Many teams do not need a big build. Decide where you sit on this spectrum first.

If a standalone portal fits better than SharePoint, see our custom portal development service.

Types of SharePoint solutions and typical timelines

SharePoint solutions by level: Basic, Medium, Advanced and Enterprise

Pick the level that matches your team size, your systems and how much automation you need on day one. A modular build lets you move up over time.

These are typical project ranges. Section 6 breaks down licensing and development cost in more detail.

The step-by-step SharePoint development process

Here is the process we follow at Nextwebi. It mirrors our standard delivery model of scoping, cost estimation, development, QA, deployment and maintenance, adapted for SharePoint.

Step 1: Define goals and success metrics

Start with the business problem, not the platform. Are you cutting approval time, replacing an ageing intranet, preparing for an audit? Pick three to five measurable targets (for example, "leave approvals under 24 hours" or "90% of policy documents in one library"). Everything later is judged against these.

Deliverables: goals document, stakeholder list, success metrics.

Step 2: Audit your current environment and content

Inventory what you have: existing sites, file shares, SharePoint version, customisations, integrations, user counts and data volume. Flag duplicate, outdated and sensitive content early. This audit decides your migration scope and removes surprises from the budget.

Deliverables: content inventory, risk and dependency list, migration scope.

Step 3: Choose the right deployment model

For most new projects, SharePoint Online is the practical default. If you need an on-premises build, see our on-premise app development service, and for cloud planning our cloud consulting and Azure cloud services.

Step 4: Plan information architecture and governance

This is the step that quietly decides whether your SharePoint feels organised or chaotic. Decide the hub and site structure, navigation, content types, metadata, naming rules and permission groups. Set governance rules up front: who creates sites, who owns content, how long records are kept, how external sharing is approved.

Deliverables: site map, metadata model, permission matrix, governance policy.

The hub carries shared navigation, search and branding, while each department keeps its own site, owners and permissions.

Step 5: Design the experience and prototype

Good SharePoint design is about findability: the right thing in two clicks, on desktop and mobile. We start with application wireframing, then move to UI/UX design that matches your brand, and test the prototype with a few real users before any build begins.

Deliverables: wireframes, visual design, clickable prototype, user feedback notes.

Step 6: Build and configure

Build in this order: configure what SharePoint already does well, automate with low-code where it fits, and write custom code only where it genuinely adds value.

• Configuration first: libraries, views, content types, search and permissions.

• Power Apps and Power Automate for forms, approvals and notifications.

• SPFx web parts (using React and TypeScript) for custom interfaces. See our React development expertise.

• .NET and Azure Functions for heavier back-end logic. See ASP.NET and .NET Core development.

Sprint-based delivery with demos every one to two weeks keeps stakeholders involved and avoids a big-bang surprise at the end.

Step 7: Integrate with your business systems

SharePoint becomes far more valuable when it talks to the tools your teams already use: ERP, CRM, HRMS, Microsoft Dynamics, Exchange, Teams, Entra ID (Azure AD) single sign-on and third-party apps. We build these through secure APIs. Related services: ERP application development, CRM application development and custom API development.

Step 8: Secure, test and fix

Test three things: does it work (functional and user acceptance testing), does it hold up (performance with real data volumes), and is it safe (permissions, external sharing, vulnerabilities). A permissions mistake in SharePoint can expose sensitive files to the wrong people, so this step deserves real time.

• Software testing and performance testing

• Web application security testing and VAPT

• Cloud security and security architecture review

Step 9: Migrate content

Move content in waves, not all at once. Clean first, map old metadata to the new model, run a pilot batch, validate, then migrate the rest with a short freeze window. We have migrated content from file shares and legacy platforms into SharePoint with minimal user disruption. Learn more about our application migration and re-engineering and cloud migration and integration services.

Step 10: Launch, train and drive adoption

A solution nobody uses is wasted money. Plan a pilot group, role-based training, short how-to guides and champions inside each department. Announce the launch on the new intranet itself so people have a reason to visit.

Step 11: Support and keep improving

After go-live, monitor usage and performance, patch and update, and review governance every quarter. Most teams add features in phase two once real usage shows what matters. Our maintenance and support team handles this, and you can also hire dedicated SharePoint developers.

Each step is explained above; the phases show where the work shifts from planning to building, proving and launching.

How much does SharePoint solution development cost?

There are two separate budgets: licensing (what Microsoft charges per user) and development (what you pay to design and build the solution). People often plan for only one.

Microsoft licensing (per user, per month, billed annually)

SharePoint Online is now bought inside Microsoft 365 plans. Microsoft is retiring the standalone SharePoint Online Plan 1 and Plan 2 licences, so new buyers should plan around the bundles below. Prices reflect the July 2026 increase.

Good to know: every tenant gets 1 TB of SharePoint storage plus 10 GB per licensed user, and extra storage is billed at about US$0.20 (₹19) per GB per month. Business plans are capped at 300 users. Always confirm current rates with Microsoft or your reseller, as regional pricing differs.

Development cost by solution type (industry ranges)

These are market ranges for professionally delivered projects, not a fixed price list. Your quote depends on scope, integrations and data volume.

Typical hourly rates by region

Offshore delivery from India, as we do from Bangalore, is how many global businesses keep quality high and cost sensible. See our offshore software development model.

What drives the cost up or down

• Number of sites, libraries and workflows

• Custom SPFx development versus configuration and low-code

• Number and complexity of integrations

• Data volume and quality for migration

• Security and compliance needs (audit trails, retention, data residency)

• Design depth and the number of user roles

• Training scope and number of locations

Costs people forget

• Ongoing support: budget around 15 to 20% of build cost per year.

• Training and change management: about 5 to 10% of project cost.

• Premium add-ons: advanced Power Automate licences, third-party permission or migration tools.

• Extra storage once you pass the tenant pool.

Ways to keep the budget under control

1. Reuse built-in SharePoint features before writing custom code.

2. Launch a focused first phase, then expand.

3. Clean content before migrating. Moving junk costs real money.

4. Fix governance early to avoid expensive rework.

5. Use a fixed-scope discovery phase to firm up the estimate.

SharePoint, AI and Copilot: what changes in 2026

AI assistants are only as good as the content they can read. A well-structured SharePoint, with clean metadata, correct permissions and current documents, is what makes Microsoft Copilot and custom AI tools useful instead of confusing. Two practical moves:

• Tidy first. Archive stale files and fix oversharing before enabling AI features.

• Add intelligence where it pays. Search across your libraries with a retrieval-augmented generation (RAG) layer, or build task-focused AI agents that answer HR or IT questions from your own documents.

If you are not sure where to begin, our AI consulting services and AI development and integration teams can map the opportunities.

Case study: SharePoint intranet for a leading aviation product manufacturer

The client. A global manufacturer of aviation components and systems, supplying commercial airlines, defence organisations and aerospace companies.

The challenge. As operations grew across departments, the company needed one internal platform for communication, IT support, HR processes and collaboration.

What we built. An internal application and team site on the Microsoft .NET framework and SharePoint platform, integrated with Microsoft Project Server for project management and resource allocation. The solution included:

• A central team site for collaboration and document sharing

• An IT support ticketing system

• An HRMS portal for employee profiles, attendance, performance reviews and leave

• A helpdesk for facilities, equipment and administrative requests

• A company news and updates section

• An organisation structure view

• A process dashboard for KPIs and project progress

• A company holiday and events calendar

The outcome. Teams collaborated better through one shared platform, the organisation structure became clear to employees at every level, and internal service requests were handled faster through the helpdesk.

FAQ'S

Q.How long does it take to build a SharePoint solution?

Simple sites take 3 to 6 weeks, intranets and document systems 8 to 14 weeks, and complex enterprise portals 4 to 9 months.

Q.SharePoint Online or SharePoint Server: which should we pick?

Most businesses choose SharePoint Online for faster rollout, automatic updates and Teams and Copilot integration. Choose on-premises only for strict data residency or isolation requirements.

Q.Can SharePoint integrate with our ERP, CRM or HRMS?

Yes. SharePoint connects to business systems through APIs, Power Automate connectors and custom services, so data can flow both ways.

Q.Is SharePoint secure?

It can be very secure when configured well: role-based access, multi-factor authentication through Entra ID, sensitivity labels, retention policies and audit logs. Security depends on setup, so we recommend testing before launch.

Q.Do we need custom code, or is Power Apps enough?

For forms and approvals, low-code is often enough and cheaper. For custom interfaces, complex logic or heavy integrations, SPFx and .NET development are the better fit. Many solutions use both.

Q. Can you migrate us from SharePoint 2013, 2016 or 2019, or from file shares?

Yes. We assess your content, clean and map it, run a pilot and migrate in waves to limit downtime.

Q.Do you offer support after launch?

Yes. We provide ongoing maintenance, monitoring and enhancements, or you can add dedicated developers to your team.
