Supplier quality control for
UK manufacturers.
Your quality system doesn't stop at the factory gate.
For UK engineering and industrial manufacturers, the supplier base is where quality is won or lost. A certified quality management system requires you to evaluate, approve, monitor and re-evaluate the suppliers you depend on, keep an approved supplier list, hold evidence of their certifications and insurances, run supplier audits and act on non-conformances. In automotive and aerospace, the bar is higher still, with IATF 16949 and AS9100 controls expected.
On top of quality, a second wave of obligations lands at once. Larger customers cascade Modern Slavery Act due-diligence expectations down their supply chains, and carbon has become a purchasing criterion, with buyers increasingly asking suppliers to disclose Scope 3 emissions. The result is a growing evidence burden that is difficult to manage in spreadsheets and email.
Approve, monitor and evidence suppliers.
Supplio does not run sourcing, RFx or e-auctions, does not issue purchase orders, and does not perform ISO certification itself. It is the system of record for approving, monitoring and evidencing suppliers, alongside your certification body and your ERP.
Branded supplier portal
A self-service portal your suppliers log into, carrying your logo, accent colour and welcome message.
Supplier onboarding
Invite a supplier, send them onboarding forms, and review submissions in a queue where you approve or request changes.
Document store with expiry tracking
Store the documents suppliers upload, with expiry dates and automatic reminders as they approach.
Certification tracking
Record each supplier certification with its issuing body, issue and expiry dates, and live status.
Risk register with a 5x5 heatmap
Log supplier risks by likelihood and impact and see them on a clickable 5x5 heatmap.
CAPA with a supplier response loop
Raise a corrective action, assign it, let the supplier respond through the portal, then accept it or send it back.
Performance scorecards
Review suppliers across multiple dimensions and see org-wide averages, top and bottom performers.
Contract repository
Store supplier contracts with start, end, notice period and renewal, and get alerted before they expire.
Scope 3 carbon reporting
Collect supplier-declared emissions, apply emission factors, and export a Scope 3 inventory as CSV or PDF.
Immutable audit log
Every change is recorded in an immutable, filterable audit log you can export to CSV.
ISO 9001, sector standards and ESG.
ISO 9001 clause 8.4: control of external providers
ISO 9001:2015 clause 8.4 is the core supplier requirement for any manufacturer holding the standard. It requires you to ensure externally provided processes, products and services conform to requirements, and to control them wherever they are incorporated into your product or delivered on your behalf.
- 8.4.1: criteria for evaluation, selection, monitoring and re-evaluation, with records
- 8.4.2: define the type and extent of control over provider and output
- 8.4.3: communicate clear requirements to providers
- An approved supplier list is effectively required by 8.4.1
Sources: ISO 9001 clause 8.4. Checked 2 July 2026.
Sector standards: IATF 16949 and AS9100
Both automotive and aerospace build on ISO 9001 but add stricter, customer-driven supplier controls. If you supply into these sectors, your customers will expect you to apply them to your own sub-tier suppliers.
- IATF 16949: risk-based supplier management and second-party audits
- Suppliers driven toward third-party certification and development
- AS9100: traceability to configuration, counterfeit-part prevention, FOD control
- Neither replaces ISO 9001; they extend it for higher-risk products

Approved supplier lists, modern slavery and Scope 3
Beyond a single standard, manufacturers maintain an operational compliance layer: who is approved to supply, on what basis, and against what wider obligations, now including carbon.
- An approved supplier list with scope, certification, risk rating and re-evaluation dates
- Supplier audits and scorecards for ongoing monitoring
- Modern Slavery Act s.54 statement required at £36m+ turnover
- Scope 3 disclosure increasingly required by customers, often via CDP; SECR context
Sources: Modern Slavery Act 2015 s.54, SECR (Carbon Trust). Checked 2 July 2026.
