Procurement software built for UK rules, from the Procurement Act to e-invoicing.

Codeeo delivers procurement software development in the UK for public bodies, the suppliers who bid to them and private groups running purchasing across several sites. We build requisitions, sourcing, supplier onboarding, contract management and invoice matching as one connected system, designed around the Procurement Act 2023, the Central Digital Platform, UK GDPR and the move toward mandatory e-invoicing, so your process stays compliant as the rules change.

UK procurement is not one regime. England, Wales and Northern Ireland follow the Procurement Act 2023, devolved Scottish authorities keep their own rules, and private buyers face duties on payment practices, modern slavery and data protection. Your software should reflect the rules that apply to you, not a generic template built for another country.

Built for
Contracting authorities, public sector suppliers and multi-site private organisations operating across England, Scotland, Wales and Northern Ireland.
Typical timeline
We agree the first release and its dates in writing at the end of discovery, and plan national rollout in waves by region, entity or department.
What you own
Code, data, supplier master records, contract archive and every cloud and app store account, owned by your organisation.

Platform capabilities

A procurement platform that works across the four nations.

A national organisation buys in more than one way at once. Head office runs strategic sourcing, regional teams raise everyday orders, finance pays from one or more ledgers, and compliance must show the whole picture to auditors, regulators or a board. Public bodies add the Procurement Act 2023 to that mix, with notices published through Find a Tender and supplier details held on the Central Digital Platform. Suppliers to the public sector carry the mirror image of those duties. The capabilities below are the national building blocks we combine for UK clients. Discovery decides the first release, and later releases follow the order your teams and auditors care about most, rather than a fixed product roadmap. Every module shares one supplier master, so a firm vetted once is recognised everywhere it trades with you.

Explain your project
  • Procurement Act notice preparation

    Internal records structured around the notices the Act requires, from pipeline and tender notices to contract award, contract details and later change or termination notices. Officers complete each stage inside the system, then publish through Find a Tender using the data already captured, by API where available or by structured export.

    Notice data is gathered as the work happens, not reconstructed at the deadline.

  • Regime-aware workflows

    Rules that change with the buyer's legal regime, so an English trust, a Welsh council and a devolved Scottish authority follow the correct procedures and portals inside the same platform. Wales can carry its socially responsible procurement duties, and Scottish bodies can follow the Public Contracts Scotland route.

    One platform respects four sets of expectations.

  • Supplier vetting with Companies House data

    New suppliers checked against Companies House records for status, officers and filing history through its public API, alongside insurance, accreditation and financial standing checks you define. Changes at Companies House can trigger a review of an existing supplier. Identity verification of directors, now part of Companies House rules, adds a further signal worth recording.

    Supplier records reflect the official register.

  • Exclusion and debarment screening

    Public buyers must consider the exclusion grounds in the Act and the central debarment list. The system records these checks for each supplier and each associated subcontractor at the right stages, with the reasoning written down where a judgement is needed. Associated persons and key subcontractors named in a bid are screened the same way.

    Exclusion decisions have a documented basis.

  • Contract management and KPI tracking

    The Act expects contracting authorities to manage contracts actively, including setting and publishing key performance indicators for larger contracts and assessing performance against them. Contract owners record scores, issues and remedies in the system, and the data feeds the performance information you are required to publish.

    Supplier performance is assessed on schedule, with evidence.

  • Payment terms monitoring

    Invoice receipt, approval and payment dates tracked against agreed terms, including the payment periods the Act implies into public contracts and subcontracts. Large companies can draw their statutory payment practices reports from the same data instead of compiling it by hand. Dashboards show which business units pay slowest and which approval steps cause the delay.

    Late payment is visible before it becomes a reporting problem.

  • E-invoicing readiness

    Invoice data held in a structured form that can be sent and received through networks such as Peppol, which some UK public buyers already use. The government has announced mandatory e-invoicing for VAT invoices from April 2029, with technical detail still to follow, so we design for change rather than guess the final format.

    The switch to e-invoicing becomes a configuration task.

  • Modern slavery and ethical sourcing

    Supplier risk scored by category and country of origin, with questionnaires, audit results and remediation plans stored per supplier. Organisations that publish a statement under the Modern Slavery Act 2015 can draw their supply chain evidence straight from these records. High risk categories such as cleaning, construction labour and textiles get deeper checks by default.

    Annual statements rest on recorded due diligence.

  • Secure bank detail changes

    Supplier bank changes held until verified through a second channel and checked with Confirmation of Payee where your bank supports it. Every change, approver and verification call is logged, which protects national finance teams from payment diversion fraud. Requests to change bank details by email alone are never actioned.

    Fraudulent bank changes are stopped before payment runs.

  • National spend and contract analytics

    Spend by category, region, entity and supplier, contract renewals across the estate, and savings tracked against baselines. Regional managers see their own area; the board sees the whole country. Contract renewals across all four nations appear in one forward calendar, with owners and notice periods. Savings and cost avoidance are recorded against agreed baselines, so claims can be audited.

    Decisions are made with national data, not regional guesses.

Who we build for

Organisations that need a UK-wide procurement system.

Nationwide procurement problems look similar from the outside and very different once you see the data. A central government arm's length body, a housing group spread across several regions, a facilities firm bidding to councils in all four nations and a retailer buying for hundreds of stores each need different controls. Codeeo works with UK clients remotely, with discovery, reviews and training all by video call from our teams in Dubai, Riyadh and Karachi. These four profiles describe where our UK projects usually begin.

01

Contracting authorities moving onto the new regime

Since the Procurement Act 2023 came into force on 24 February 2025, contracting authorities have needed new notices, new procedures such as the competitive flexible procedure, and new contract management duties. Many still run on systems built for the old regulations. We build or extend internal tools so pipeline planning, procedures, evaluation, award and contract management follow the Act, while publication stays on Find a Tender and supplier data stays on the Central Digital Platform. Old contracts let under the previous regulations can sit beside new ones, each following the rules that applied when it was awarded.

Your legal advisers confirm interpretation; we build what they specify.

02

Suppliers bidding across the UK public sector

Firms that sell to councils, NHS bodies and central government answer similar questions in every tender, keep their core information on the Central Digital Platform and report on contracts after award. We build bid libraries, evidence stores, contract performance trackers and key performance indicator reporting, so national bid teams work from one source and stop reinventing answers for each buyer. Subcontractor details and payment performance can be tracked too, since buyers increasingly ask how quickly you pay your own supply chain.

03

Multi-site private groups

Retailers, care providers, logistics firms and manufacturers with sites across the country need local purchasing freedom within central control. We build catalogues, approval rules by site and region, and mobile approvals for area managers, linked to one supplier master and one or more finance systems, with reports that show compliance by site. New sites can be added in the admin system without a development change, which matters for groups that acquire or open locations regularly. Regional buyers can raise one-off requests outside the catalogue, but those requests reach a central category manager first.

04

Organisations working in Wales or Scotland

Welsh public bodies balance the Procurement Act with their own socially responsible procurement duties and Welsh language standards, and devolved Scottish authorities follow Scottish procurement law. We design interfaces that can run in Welsh and English where needed, and workflows that keep each nation's procedures distinct inside one platform. Northern Ireland bodies follow the Act too, with their own central purchasing arrangements reflected in the configuration. Reporting can split figures by nation, which helps groups answering to more than one government.

A national rollout in six stages.

  1. 01Regime and policy reviewWe establish which procurement regime applies to each part of your organisation, then map your policies, delegation limits and audit findings against it. Where parts of the group sit under different rules, each part is mapped separately so nothing is assumed.
  2. 02Process discovery by regionVideo sessions with central and regional teams reveal where national policy and local habits differ, and which differences are justified. We also speak to a few suppliers, because their experience exposes delays buyers often miss.
  3. 03Platform designData model, roles, approval rules and interfaces designed once, with configuration for regions, entities and nations, checked against WCAG 2.2 for accessibility. Screens are tested with staff who buy rarely as well as with full-time buyers.
  4. 04Build and integrateSprint releases connected to finance systems, identity providers, Companies House and government services, each demonstrated on a recorded call. Data migration scripts are rehearsed on copies before real records move.
  5. 05Pilot regionOne region or entity goes live first, proving rules, integrations and reports under real demand before the wider organisation follows. Pilot users report problems through a simple form, and fixes ship within the pilot period.
  6. 06Rollout wavesFurther regions join in planned waves, each with training, data migration and a short review period, until the whole country runs on one system with one supplier master. Each wave is signed off before the next begins.

Technology

What we build this with.

Builds typically use .NET or Node services, React interfaces and Flutter mobile apps, hosted in UK cloud regions on Azure or AWS. Integration layers are designed for change, since government services, e-invoicing standards and finance systems will all move during the life of the platform. Sign in runs through your existing identity provider for staff, with separate secure access for suppliers.

Questions UK organisations ask about procurement software.

A system shaped to your regime, your policies and your finance setup.

Expect discovery first: which procurement regime applies, how purchasing works across your sites, which systems hold supplier and finance data, and what auditors have flagged. From that we write a scope and a phased plan. The first release covers the steps that cost you most today; later phases extend across regions and modules once people are using the system. You also get a written record of every decision, so people joining the programme later understand why the system works as it does.
