The challenge

What this looks like today

A contract auto-renews for another year because nobody diarised the notice period.

The same supplier is on three different rate cards across three departments.

Purchase approvals happen in email, so spend is only visible after it's committed.

The obligations you signed up to are buried on page 34 of a PDF.

The product

Everything you'd expect from Castia Procure

The features you'd want from any tool in this category — because this is a product, not a plugin.

Supplier records

One record per supplier: contracts, contacts, spend history, performance, and risk rating.

Purchase orders & requisitions

Raise, approve, and track POs against budget before the money is committed.

Contract repository

Every agreement in one searchable place, with key dates and terms extracted onto the record.

Approval workflows

Route spend by value, category, and policy, with the audit trail intact.

Spend analytics

Spend by supplier, category, and cost centre — including the duplicate suppliers you didn't know you had.

…and everything you can’t get anywhere else

Castia Procure is built on the Castia platform — so enterprise search, knowledge AI, reporting, workflow automation, and agents all apply directly to your work.

Contract intelligence

Read every contract and extract the term, notice period, renewal date, price escalators, and liability caps automatically.

Renewal watch agents

An agent that tracks every notice window and tells you 90 days out — with the negotiation position already drafted.

Ask your spend

"Where are we paying two suppliers for the same service?" — answered across every entity and cost centre.

Search every clause

Find every contract with an uncapped liability, or an auto-renew, or a clause you now regret — in one query.

Supplier reporting

Consolidated spend and performance reporting, generated rather than assembled.

Procurement platforms charge per user, so requesters raise POs by email and the whole point is lost. Castia charges for usage — let the whole business raise a requisition properly.
