Modern SharePoint,before Microsoftforces the switch.

Classic SharePoint is being retired in 2026. Add-ins, Designer workflows, and InfoPath are all reaching end of life. If your organisation still runs classic sites, the clock is ticking. We build modern SharePoint development services — SPFx web parts, Power Automate workflows, Viva Connections intranets — and migrate classic environments before Microsoft switches them off.

Why Entalogics for SharePoint

Four things every
SharePoint environment
actually needs.

The SharePoint environments we inherit always have the same problems — classic sites with custom master pages that break on every update, InfoPath forms with no migration plan, Designer workflows that Power Automate needs to replace, and permissions so complex that nobody can explain who has access to what.

Architecture01

Modern sites with SPFx — not classic pages with injected scripts.

SPFx web parts and extensions are the only supported customisation path. Script Editor, Content Editor, and custom master pages are deprecated. We build on SPFx with React and TypeScript — the same stack your web developers already know.

Automation02

Power Automate replaces Designer workflows. No exceptions.

SharePoint Designer workflows retire in 2026. Power Automate handles approvals, notifications, document routing, and cross-system orchestration. We migrate workflow by workflow with proper error handling and monitoring.

Governance03

Permissions that are auditable, not inherited chaos.

Site-level permissions, hub-level governance, Microsoft Purview for compliance labels. No broken inheritance chains. No "everyone" groups with edit access. Permissions that your compliance team can actually audit.

Migration04

Classic to modern before Microsoft forces the switch.

Page transformation, web part replacement, navigation redesign, branding via modern theming. 40–60% of classic content is stale and shouldn't migrate — we audit first, migrate what matters.

When SharePoint, when not

SharePoint is a platform.
Not every problem belongs on it.

SharePoint handles document management, intranets, and team collaboration better than most alternatives. It's also Microsoft's platform — and if you're not a Microsoft shop, the integration value disappears. We'll tell you on the first call if SharePoint is the right fit.

BUILD ON SHAREPOINT WHEN

  • You're a Microsoft 365 organisation — Teams, Outlook, OneDrive are already your workplace
  • Document management with version control, metadata, and retention policies is a core need
  • Intranet with Viva Connections for company news, communications, and employee engagement
  • Compliance and governance requirements that Microsoft Purview handles natively

CONSIDER ALTERNATIVES WHEN

  • You need a custom web application that happens to manage documents — a purpose-built app may be simpler
  • Your organisation doesn't use Microsoft 365 — SharePoint's value is in the ecosystem integration
  • The use case is a public-facing website — SharePoint is not a CMS for external audiences

WE SAY NO WHEN

  • "SharePoint as a customer-facing website." That's not what it's for.
  • "Keep running classic sites and hope for the best." Microsoft is retiring them. Hope isn't a plan.
  • "Migrate 500 classic sites in three weeks." That ship has sailed.

The playbook

Patterns we
ship on repeat.

SharePoint patterns from real enterprise deployments — not tutorial screenshots.

  • P01

    SPFx with React and TypeScript

    Every custom component built as an SPFx web part with React. Typed Graph API calls. Unit tested with Jest. Deployable to SharePoint, Teams, and Viva from one package.

  • P02

    Hub site architecture

    Hub sites for department-level governance. Communication sites for publishing. Team sites for collaboration. Navigation inherited from hubs — not manually maintained on 200 sites.

  • P03

    Power Automate with error handling

    Every workflow has a try-catch pattern, failure notifications, and run history monitoring. No silent failures. No workflows that stop working and nobody notices for a month.

  • P04

    Metadata over folders

    Documents tagged with content types and managed metadata. Views filter by metadata. No 10-level-deep folder structures that nobody navigates.

  • P05

    Purview labels from day one

    Sensitivity labels for confidential documents. Retention labels for compliance. DLP policies preventing external sharing of sensitive content. Governance automated, not manual.

  • P06

    Page transformation for migration

    SharePoint Page Transformation framework for converting classic pages to modern. Content audit before migration — stale content archived, not migrated.

Signature case

An enterprise intranet,
migrated from classic SharePoint to Viva Connections.

A 12,000-employee organisation on classic SharePoint — 340 sites, 86 custom master pages, 120 Designer workflows, 45 InfoPath forms, and permissions so broken that HR documents were accessible to the entire company. Migrated to modern SharePoint with Viva Connections, Power Automate, and Power Apps in 14 weeks. Permissions audited and fixed. 58% of content archived instead of migrated.

Before

340 classic sites · 86 master pages · 120 Designer workflows · 45 InfoPath forms · broken permissions

After

142 modern sites · SPFx branding · Power Automate workflows · Power Apps forms · audited permissions

  • Sites migrated (post-audit)340 → 142
  • Content archived58%
  • To fully modernised14wk
  • Permission violations fixed100%

Engagement shape

Eight to ten weeks
to a measurable ship.

A typical SharePoint development engagement. We migrate or build site by site — the current environment stays live while we work.

  • W01

    Audit + RFC

    Two senior SharePoint developers. Classic site inventory, workflow audit, InfoPath dependency scan, permissions review. A ranked, dollarized RFC.

  • W02–03

    Foundation + first site

    Modern site architecture established, SPFx branding deployed, hub site configured, first site migrated end-to-end. Live in production.

  • W04–08

    Site by site

    Pages transformed, workflows migrated to Power Automate, forms rebuilt in Power Apps. The classic environment keeps running throughout.

  • W09+

    Governance + handoff

    Purview labels applied. Permissions audited. Governance runbook handed to your team — or we stay on retainer.

FAQ

Sharp questions,
straight answers.

Classic retirement, migration timelines, branding — the questions we get on every SharePoint discovery call.
Yes. Microsoft is retiring classic add-ins, ACS authentication, Designer workflows, and InfoPath through 2026. Classic sites won't disappear overnight, but customisations built on deprecated features will stop working. Migration to modern SharePoint is the only supported path.
12–20 weeks for a typical enterprise. Content audit first — 40–60% of classic content is stale and shouldn't migrate. The rest transforms site by site using page transformation and SPFx rebuilds for custom web parts.
Yes — via SPFx Application Customizers for headers, footers, and mega menus, plus tenant-level theme configuration for colours and fonts. Custom master pages are gone, but SPFx provides equivalent branding control.
Yes. The engineers who write the RFC ship the migration. No handoff mid-engagement. Direct access throughout.
Yes. We audit what's there, classify content as migrate/archive/retire, and modernise site by site. The classic environment stays live until every site has earned its migration.
