Approval workflows enterprises can trust
Approvals too often live in inboxes: no audit trail, unclear ownership, stalled requests. Barrington designed, built and shipped two approval applications — a ground-up procurement platform and a focused enhancement to a hiring system already in production — that remove the trade-off between control and usability.
The procurement platform
A governed request-to-PO workflow taking a Request to Procure from creation through review, approval, sourcing and purchase-order issuance — fully aligned to group procurement policy.
- Five governed roles with least-privilege permissions.
- A parallel approval engine: mandatory SME sign-off alongside optional Legal and InfoSec reviews; any rejection ends the request.
- Policy-driven routing: requests of €10,000 or more automatically enter a sourcing stage — enforced by the system, not by memory.
- An immutable audit trail: who did what, when and why, at every transition.
- Role-based spend dashboards and notifications in Teams and email.
The hiring approvals upgrade
The client’s existing hiring app handled approvals over email and Teams. Executives wanted to approve in-platform without losing the channels they relied on.
- A dedicated, view-only Approver role with rights to approve or reject at defined stages.
- In-app approvals added at the two moments that matter: authorising a hiring request, and signing off the final offer.
- Multi-channel by design — app, Teams or inbox — so adoption never depends on changing habits.
- Scoped, built, tested and documented for a fixed price.
How we work
Different in size, the two projects share the same discipline: governance by design, adoption through convenience, and fixed scope delivered with certainty.
Governance by design: every status change is logged and creation records are immutable — so audit and compliance teams get a defensible trail without chasing emails.
