Microsoft Fabric Workload
Enterprise Planning,
Native to Microsoft Fabric.
K4 is now available as a Fabric workload — a native planning engine that lives inside your workspace, powered by a 100% Excel-compatible spreadsheet, with real-time write-back to SQL and OneLake. With embedded AI through K4 Surfaces.
FULL STACK INTEGRATION
The K4 + Microsoft Stack
K4 integrates across every layer of the Microsoft ecosystem — from identity to data to visualisation — without requiring you to replace, re-architect, or re-train.

K4 is the planning layer that connects Fabric's data capabilities to the spreadsheet experience your finance team already uses — no migration required.
WHY K4
The Planning Layer Fabric Was Missing
Fabric gives you a world-class data platform. K4 gives you the planning engine that sits on top of it — without asking your finance team to change anything.
01
A single planning layer — not a patchwork of tools
Many solutions claiming Fabric integration are collections of separate products stitched together. K4 is a single cohesive workload: one data model, one security layer, one user experience. Less complexity, less vendor risk, less maintenance.
03
AI that builds your apps — not just explains your data
Most AI integrations in planning tools are analytics copilots that describe what your numbers show. K4 Surfaces goes further: describe what you need in plain language and AI generates the entire operational planning interface — approval workflows, driver-based models, simulation panels — running live on your Fabric data.
02
Excel is not the problem. Ungoverned Excel is.
K4 does not replace Excel — it governs it. Finance teams keep working in the spreadsheet environment they know while IT gets a SQL-native, Fabric-integrated data layer with full row-level security. Nobody loses anything. Everyone gains.
04
Fabric-native governance, not retrofitted from outside
K4 was designed from the ground up to respect your existing Fabric governance policies. Row-level security, workspace permissions, and Entra ID groups all carry through without extra configuration. Your IT team gets compliance out of the box.
K4 SURFACES · AI IN FABRIC
AI That Builds Your Planning Apps. Inside Fabric.
Most AI integrations in planning tell you what your data means. K4 Surfaces does something far more powerful: it generates the operational planning interface itself — approval workflows, simulation panels, driver-based models — from a plain-language prompt. All running live on your Fabric data.
-
Vibe Coding: Describe your planning use case in plain language. K4 builds the model.
-
AI-Generated Surfaces: Kanban boards, approval flows, and scenario panels created from a single prompt.
-
Live Fabric Execution: Every AI-generated surface runs on real data from your OneLake or SQL Server.
-
No Developer Required: Finance teams build and deploy planning applications without writing code.
WHAT'S INCLUDED
Everything in One Workload
Native Fabric Workload
K4 lives directly inside your Fabric workspace — not linked from an external SaaS. Your planning layer belongs to your tenant, governed by your rules.
100% Excel-Compatible — Not "Excel-Like"
K4 embeds a fully Excel-compatible spreadsheet engine inside your planning models. Every formula, every format, every function works exactly as your finance team expects — with no proprietary syntax to learn and no migration of existing models.
Real-Time Write-Back to OneLake
Users type into K4 models in Power BI and data is written back instantly to SQL or Fabric OneLake. No exports. No manual entry. No reconciliation headaches.
Your Data Never Leaves Your Tenant
Planning data stays in your SQL Server or Fabric OneLake. K4 is a thin client that reads and writes to your existing data layer — zero external data exposure.
Entra ID SSO — Zero Friction
Authentication is handled natively through Microsoft Entra ID. No separate credentials, no extra configuration. Your existing identity stack just works from day one.
AI-Powered by K4 Surfaces
Vibe Coding lets users describe a planning use case in plain language and K4 Surfaces generates the full interface instantly — Kanban boards, approval flows, simulation panels, all live on Fabric data.
SECURITY & IDENTITY
Zero New Credentials.
Zero Shadow IT.
IDENTITY
Entra ID Single Sign-On
K4 authenticates users through Microsoft Entra ID natively. Users are in with one click — no separate login page, no new password to manage. Azure AD groups and conditional access policies apply automatically.
DATA SOVEREIGNTY
Your Tenant, Your Data
All planning data lives in your SQL Server or Fabric OneLake. K4 never stores, syncs, or caches your financial data externally. Your compliance team gets what they need on day one.
GOVERNANCE
Row-Level Security Inheritance
K4 inherits SQL and Fabric row-level security without re-configuration. A user who cannot see a cost centre in Power BI cannot see it in K4 — the same rules, the same enforcement, zero overhead.
DEVELOPER FLEXIBILITY
API Key Fallback
For programmatic access, integration pipelines, or CI/CD workflows, K4 also supports API key authentication — giving developers flexibility without compromising your security architecture.
