Most companies that take responsible purchasing seriously start in the same place: a policy commitment, a set of principles, and a gap between what they have agreed to do and what their buyers actually do from day to day.
Closing that gap is the real work of implementation. It requires change to internal processes, commercial incentives, buyer training, supplier relationships, and the way progress is tracked and reported.
This page walks through implementation using the five principles of the Common Framework for Responsible Purchasing Practices (CFRPP) as its structure. The CFRPP was developed with brands, suppliers, and trade unions precisely to make implementation concrete and navigable, whatever a company's starting point. Sector-specific versions of the framework are available for apparel and textiles, food, and manufacturing. This page draws on all three.

Why implementation is harder than policy commitment
The distance between a responsible purchasing policy and responsible purchasing in practice is well documented. Companies can commit publicly to the principles of the CFRPP while their buyers continue to place late orders, negotiate prices below the cost of production, and change specifications without notice. This is not usually a failure of intention. It reflects the structural difficulty of changing commercial behaviour that has been shaped over years by cost, speed, and volume pressures.
Implementation requires more than training buyers on the principles. It requires aligning commercial incentives so that buyers are not rewarded for behaviour that harms suppliers. It requires building internal accountability so that commitments made by sustainability teams are reflected in the decisions made by procurement teams. And it requires sustained engagement with suppliers, whose experience of purchasing practices is the most reliable indicator of whether real change is happening.
The CFRPP is designed with this in mind. Under each of its five principles, it offers practices to implement and build on as companies develop their approach, recognising that a practice that works well in one context may create unintended pressure in another. The framework is intended as a reference point for conversations with internal teams and suppliers, not a checklist to be completed in isolation.
Principle 1: Integration and reporting
Responsible purchasing practices need to be embedded across the business, not owned by the sustainability team alone. This is the starting point, and arguably the hardest principle to implement, because it requires change at leadership and governance level before individual practices can shift.
Integration means that top leadership is visibly committed to responsible purchasing, that purchasing practices are integrated into commercial strategy and decision-making processes, and that buying functions have genuine ownership of RPP rather than treating it as a compliance exercise. It means reviewing existing supplier relationships and purchasing systems to understand where negative human rights impacts are occurring or could occur, and using that assessment to set priorities.
Reporting is the accountability mechanism that makes integration real. Internal KPIs for purchasing practice improvement need to sit alongside – and carry comparable weight to – commercial KPIs. External reporting should reflect honest progress and not just policy statements. The CFRPP guidance includes specific practices for establishing these governance and accountability structures, from initial groundwork through to more advanced stages of integration.
ETI's RPP Resource Hub includes tools and exercises specifically designed to support buyer training and internal buy-in, including video content that can be used with commercial teams who may be less familiar with the human rights dimensions of their work.
Principle 2: Equal partnership
Equal partnership means treating suppliers as business partners with shared responsibilities, rather than as interchangeable sources of supply. In practice, this involves a shift in how companies structure their supplier relationships over time: reducing the churn of suppliers, building longer-term and more secure sourcing relationships, and developing mutual agreements on responsibilities for responsible purchasing.
Communication is central to equal partnership. This includes how buyers engage with suppliers on critical path planning, how feedback from suppliers on purchasing practice impacts is gathered and acted upon, and how problems are solved when they arise. The CFRPP is specific that force majeure clauses should only be used responsibly, that exit strategies should be handled in a way that does not leave suppliers bearing disproportionate cost, and that supplier feedback should be an integral part of any improvement plan rather than a box-ticking exercise.
A consistent finding from ETI's work across sectors is that inviting honest supplier feedback on buyer behaviour changes the dynamic of the relationship. When brands approach suppliers with genuine openness to learning about the impact of their own decisions, the conversation shifts from risk management and auditing to systemic improvement. In a number of cases within ETI's manufacturing initiative, this shift also improved outcomes on broader human rights and due diligence issues.
Principle 3: Collaborative production planning
Critical path and production planning done collaboratively between buyer and supplier is one of the most direct ways to reduce purchasing-related harm. When planning is unilateral – with buyers setting timelines and specifications without meaningful supplier input – the risk of unrealistic lead times, excessive sampling demands, and last-minute changes is much higher. The consequences for workers, in terms of forced overtime and unpredictable working hours, are well evidenced.
Collaborative planning requires buyers to provide accurate technical specifications early, to improve the accuracy of their forecasting, to balance order volumes across suppliers, and to take responsibility for delays caused by their own missed deadlines rather than passing the costs of those delays to suppliers. It also requires tracking the reasons for delays in the critical path systematically, so that patterns can be identified and addressed.
For many companies, meaningful improvement in production planning requires change to internal processes that go beyond the purchasing team. Design and product development timelines, approval processes, and sign-off procedures all affect what is actually achievable in production. The CFRPP guidance points to the importance of streamlining these upstream processes as part of responsible purchasing implementation.
Principle 4: Fair payment terms
Payment terms that are fair, transparent, and agreed by both parties, with payments made in full and on time, are a fundamental condition of a responsible purchasing relationship. Late payment is one of the most damaging purchasing practices for suppliers and workers: when buyers pay late, suppliers face cashflow pressure that can affect their ability to meet payroll on time, invest in their operations, or maintain safe working conditions.
Fair payment terms means more than paying on time, although that is the starting point. It also means working actively to improve payment timelines where they are long, agreeing reasonable penalty clauses that take into account the cause of any delivery delays rather than imposing automatic penalties, and ensuring that payment processes are transparent and well understood by suppliers.
The EU Unfair Trading Practices Directive and the UK Groceries Supply Code of Practice both contain specific provisions on payment terms and late payment in relevant sectors. Improving payment practices is therefore both a responsible purchasing commitment and, in many cases, a legal compliance requirement. For more on the legislative context, see RPP and legislation.
Principle 5: Sustainable costing
Sustainable costing means that the prices a company pays reflect the actual costs of production in line with responsible business conduct, allow for a reasonable and maintained supplier profit margin, and support wage increases over time – including progress towards a living wage. This is perhaps the principle most directly connected to worker outcomes, because it addresses whether the economics of the supply relationship allow workers to be paid decently.
Implementing sustainable costing requires developing mechanisms to ensure that pricing accounts for all labour costs, including when those costs increase through national minimum wage increases or collective bargaining. It means engaging with suppliers on costing in an open and transparent way, rather than simply applying downward price pressure and expecting suppliers to absorb increases.
This does not require companies to pay any price a supplier names. It does require that costing conversations are grounded in an honest understanding of what production actually costs, and that companies have a strategy for how their pricing will support rather than undermine the wages of the workers who make their products. For sector-specific guidance on sustainable costing, see responsible purchasing practices by sector.
Measuring and reporting on purchasing practice improvement
Implementation without measurement produces policy commitments rather than change. Companies that are making genuine progress on responsible purchasing practices are tracking that progress, gathering evidence of what is working, and reporting honestly on where gaps remain.
Measurement in this area is not straightforward. The most meaningful data on whether purchasing practices are improving comes from suppliers – through structured feedback mechanisms, supplier surveys, and direct dialogue. Buyer self-assessment, while useful for internal governance, does not capture how purchasing behaviour is experienced on the ground. ETI's tools and guidance support companies in developing supplier feedback processes that are systematic, regular, and genuinely acted upon.
External reporting on purchasing practices is developing rapidly. Several voluntary and regulatory frameworks now ask companies to report on their purchasing practices as part of broader due diligence disclosures. ETI member companies can access peer learning on reporting approaches through Learning and Implementation Communities.
Common barriers and how to navigate them
ETI's experience across sectors points to a consistent set of barriers that companies encounter when implementing responsible purchasing practices.
The most common is the misalignment between sustainability commitments and commercial incentives. Buyers who are assessed and rewarded on cost, speed, and margin are unlikely to change their behaviour in response to a policy statement alone. Addressing this requires changes to how buyers are incentivised and evaluated, which is a leadership decision, not a procurement decision.
A second common barrier is the perception that responsible purchasing is incompatible with commercial efficiency. ETI's work consistently shows the opposite: improvements in forecasting accuracy, sampling processes, and supplier communication tend to produce efficiency gains as well as human rights benefits. Making this case internally, with evidence from peer companies and ETI member experience, is often the most effective route to securing commercial team buy-in.
A third barrier is uncertainty about where to start, particularly for companies with large and complex supplier bases. The CFRPP's staged approach – with initial practices, intermediate steps, and more advanced commitments under each principle – is designed to give companies a navigable entry point regardless of their starting position. ETI's RPP Resource Hub provides practical tools and exercises for each stage.
