Stop chasing approvals across email threads and spreadsheets.

Our Procurement & PO Services

End-to-end purchase order and procurement tools built around your exact approval rules, supplier relationships, and spend controls.

Purchase Order Management

Create, amend, and track purchase orders with flexible PO creation, multi-currency support, and structured approval workflows that match how your team actually operates.

Approval Workflows

Configure highly specific, multi-tier approval chains based on spend thresholds, departments, or supplier type — with automated notifications so nothing sits in a queue unnoticed.

Supplier Management

Maintain detailed supplier records including pricing terms, performance KPIs, certifications, and preferred supplier rules — all in one structured, searchable system.

Requisition-to-PO Flow

Automate the journey from purchase request to approved PO with structured requisition forms, budget checks, and approval routing — eliminating manual handoffs and email chains.

Budget Tracking & Alerts

Set budget limits by category, department, or supplier and receive real-time alerts when thresholds are approached or breached — keeping spend firmly under control.

Three-Way Matching

Automatically reconcile purchase orders, delivery receipts, and supplier invoices to catch discrepancies before payment — backed by a complete audit trail for compliance.

Total Spend Control

Procurement Software Built Around Your Approval Rules

Most procurement tools force your team to adapt to their rigid workflows. Keel builds purchase order requisition software around the approval hierarchies, spend controls, and supplier processes you already use. Whether you need single-click approvals for low-value orders or multi-tier sign-offs for major purchases, the system is modelled to your exact rules — with real-time budget visibility, automated notifications, and a tamper-proof audit trail that satisfies finance and compliance teams alike.

The Keel Difference

Why Choose Keel for PO Requisition?

Keel was built by operators who lived the pain of inflexible procurement tools firsthand. Here's what makes us different.

Built for Operators

Founded by ex-Echo executives who built custom procurement tools at scale — we understand the real operational pain of broken PO processes.

Fully Customisable

Every approval chain, spend threshold, and supplier rule is modelled to your exact process — not forced into a generic template that doesn't fit.

Live in Weeks

Go from requirements to a production-ready procurement system in weeks, not months — with full handover so your team owns the platform completely.

Audit-Ready Compliance

Every requisition, approval, and PO amendment is logged with a complete, tamper-proof audit trail — essential for regulated industries and finance teams.

Meet the Team Behind Keel

Operators turned builders, on a mission to give every team the tools they deserve.

Keel was founded in 2021 by three former executives from Echo — Europe's fastest-growing online pharmacy, later acquired by Pharmacy2U. As CEO, CTO, and CPO at Echo, the founders built custom procurement and operations software to ship 50,000 medicines daily to 600,000 customers, scaling the business to $130m in annual revenue. They experienced first-hand how off-the-shelf tools failed in high-stakes, regulated environments — so they built the solution they wished existed. Backed by $6m in seed funding from Earlybird and LocalGlobe, Keel is on a mission to empower operators everywhere with flexible, powerful software they truly own — replacing the archaic ERPs and chaotic spreadsheets that slow modern businesses down.
