Procurement

Purchasing that runs on rules, with every supplier, order and payment accounted for.

Why procurement is slow and hard to control

Purchase requests, approvals, orders and supplier invoices pass between people, portals and the ERP. Each hand-off is a delay and a chance for error, and vendor risk is checked once at onboarding, then rarely again.

  • Manual hand-offs

    Requests, orders and invoices are re-entered between systems.

  • Vendor risk out of date

    Supplier checks happen at onboarding and rarely after.

  • AI agents that cannot pay safely

    Agents can find and compare, but buying needs authority, limits and an audit trail.

What changes

  1. Orders that flow

    Requests, orders, invoices and payments synchronised with the ERP.

  2. Purchasing within mandates

    Autonomous purchasing under cryptographic mandates (AP2), with limits and audit.

  3. Vendor risk kept current

    Supplier data checked continuously against KYC, AML and compliance sources.

What we deliver

  • Agentic purchasing (AP2)

    Agent Payments Protocol integration, so agents buy only within a mandate the business has signed.

  • Order and invoice synchronisation

    Purchase orders, goods receipts, invoices and payment runs synchronised with the ERP over REST, OData, IDoc or EDI.

  • Supplier invoice processing

    Document AI that extracts and validates supplier invoices, with people reviewing exceptions.

  • Vendor risk management

    Third-party connectors to KYC, AML and tax providers, and workflows for supplier reviews.

  • Approval workflows

    BPMN workflow automation for requests and approvals across departments.

Systems it connects

  • ERP

    SAP, Oracle, Microsoft Dynamics 365, Odoo or Sage, for orders, receipts and payments.

  • Suppliers and marketplaces

    Supplier portals and partners through APIs, webhooks and EDI.

  • Tax and e-invoicing

    Clearance platforms for the invoices suppliers send and receive.

How we work

  1. Map the purchase-to-pay flow

    Every step, system and approval from request to payment.

  2. Automate the hand-offs

    Synchronise orders and invoices first, then add document AI.

  3. Add agents within mandates

    Agentic purchasing goes live only with limits, mandates and an audit trail in place.

How to start

What happens next

  1. Agreeing a time

    Our team emails you to agree a time for the session.

  2. Pre-consulting session

    A free 30-minute online pre-consulting session: we go through your goals, systems and constraints.

  3. Readiness review

    In a free 48-hour readiness review, a Principal Architect checks your project against the 6-point Definition of Ready and recommends the track that fits.

  4. Choosing the track

    Scope-ready projects receive a binding proposal within 3–5 business days. Concept-stage projects start in the Blueprint Studio. A live system that is failing, undocumented or needs integration starts with a diagnostic of 1–2 weeks. The Blueprint Studio and the diagnostic each have a fixed fee, quoted in the proposal.

  • AI-native product teams

    Managed, cross-functional pods of senior engineers, equipped with agentic coding and QA harnesses.

  • Fixed-outcome projects and round-the-clock managed services

    Fixed-scope, milestone-driven delivery with named delivery leads, and round-the-clock application managed services under SLA governance.

Questions and answers

What is AP2?

The Agent Payments Protocol: a way for AI agents to pay under a cryptographic mandate the business has signed, with limits and a record of every purchase.

Do people stay in control?

Yes. Agents act within mandates, and people supervise them (human-on-the-loop), approving anything outside the rules.

Can you connect suppliers who only use EDI?

Yes. We exchange EDI with suppliers and translate it to and from the ERP, alongside APIs and portals.

Where should we start?

With the order and invoice synchronisation, which removes the most manual work, then agentic purchasing once the data is reliable.
