Osuria vs Senta: IRIS-Owned Practice Management, or a Dedicated Client Workspace? (2026 Comparison)

A sourced comparison of Osuria and Senta for UK accounting firms — Senta's per-user pricing, its bundled client portal, and what it means that Senta is now part of IRIS Software Group alongside IRIS OpenSpace.

Osuria Team

If you've already compared Osuria against IRIS OpenSpace, Senta is worth a second look for a specific reason: it's also owned by IRIS Software Group. IRIS acquired Senta, a Bristol-founded practice management platform, in January 2021, and it now sits in the same portfolio as OpenSpace — but as a separate, standalone product with its own client portal, not a module bundled into IRIS's core accountancy software. For UK firms evaluating the IRIS family of products, that distinction matters more than it first appears.

What Senta Actually Is

Senta is a cloud-based practice management platform built for accounting and bookkeeping firms, with a particular focus on smaller UK firms. Its feature set includes client relationship management, workflow and task automation, deadline tracking, automated client communication, and a secure, branded client portal for document sharing. A notable UK-specific feature is direct integration with Companies House, letting firms pull company information without leaving the platform — a detail that reflects Senta's UK-first design rather than a US product adapted for the UK market.

Third-party pricing trackers list Senta's Basic plan starting at $29 per user per month, with a free trial available; Senta does not appear to publish a self-serve pricing page, so firms should confirm current rates and plan tiers directly with Senta or through an IRIS sales conversation. The client portal itself is described as a secure, branded space for document sharing and client communication, and user reviews specifically call out the portal as one of the platform's strengths.

Because Senta is now part of IRIS Software Group, firms already using IRIS OpenSpace (bundled into IRIS's practice and accountancy software) should be clear that Senta is a different, separately-priced product aimed at firms that want full practice management — not simply a rebrand or upgrade path from OpenSpace. The two can coexist in IRIS's portfolio addressing different needs: OpenSpace as a document-exchange add-on for firms already on IRIS accountancy software, Senta as a standalone practice management system with its own portal for firms that want to run their whole practice on it.

What Osuria Actually Is

Osuria is a branded digital workspace built specifically for the client-facing layer of an accounting firm's operations: secure document sharing and structured document collection, centralized client communication in place of scattered email threads, proactive and scheduled client notifications, task requests, and a client experience that carries the firm's own brand. It isn't a practice management system — it doesn't do CRM, workflow automation, time tracking, or billing for internal staff. It's designed to sit alongside whatever a firm already uses for those functions and solve the client communication and document exchange problem specifically, independent of which practice management vendor (IRIS-owned or otherwise) a firm has chosen. Osuria does not publish self-serve pricing; firms request a walkthrough directly to get a number tailored to their firm's size and needs.

Which One Actually Fits Your Firm

If your firm is a smaller UK practice shopping for practice management from scratch — CRM, workflow, deadline tracking, and a portal together — Senta is a legitimate, UK-built option, and its reported per-user starting price is competitive against some of the larger practice-suite platforms. Being part of IRIS Software Group also means it benefits from that group's UK compliance focus, evident in features like the Companies House integration.

If your firm already runs practice management software — from IRIS or elsewhere — and the actual gap is specifically the client-facing experience, replacing your whole stack to get to a different vendor's portal is a heavier lift than the problem calls for, especially if you're only trying to solve document collection and communication. That's the case for a standalone workspace like Osuria: it doesn't ask you to consolidate onto (or migrate away from) any particular practice management vendor's ecosystem, IRIS-owned or not, just to get a portal your clients will actually use.

See It for Yourself

This comparison is directional, not a substitute for testing either platform against your own firm's client base and existing tool stack. If your real pain point is specifically client communication and document collection rather than practice management as a whole, it's worth seeing what a dedicated, branded workspace looks like next to a portal that's bundled inside a wider practice management suite.
