Weighted scoring across procurement-specific criteria. These platforms excel in different dimensions — the right choice depends on your primary tail spend challenge.
These tools solve fundamentally different tail spend problems. The best procurement stacks often include both.
Your tail spend challenge is maverick buying and lack of visibility into what your organisation purchases. Amazon Business channels that decentralised buying into a compliant, catalogued process with approval workflows, analytics and business pricing. It works best for indirect goods — office supplies, IT accessories, MRO, lab consumables — where specification is simple and speed matters more than competitive sourcing.
Your tail spend challenge is that low-value purchases go un-competed because procurement teams lack the capacity to run RFQs on sub-threshold spend. Fairmarkit automates the competitive sourcing process — soliciting quotes, analysing bids and recommending awards without manual effort. The 11.4% average savings is the headline; the 10x efficiency multiplier is equally valuable for procurement teams stretched across high event volumes.
Your tail spend spans both known-item catalogue purchases and non-catalogue services or custom requirements. Amazon Business handles the former; Fairmarkit handles the latter. Many enterprise procurement teams deploy Amazon Business as a fast-channel for routine indirect goods and Fairmarkit as the sourcing automation layer for everything that needs competitive bidding — from facilities services to custom fabrication to IT professional services.

Amazon Business is not a procurement platform in the traditional sense — it is a compliant buying channel that reduces maverick spend by making the Amazon marketplace accessible within your procurement workflows. Its ERP integrations (punchout catalogues for SAP Ariba, Coupa, Oracle, Jaggaer) mean requestors can buy from Amazon's vast product catalogue while maintaining approval workflows, spend visibility and policy compliance. The value proposition is clear: if your organisation has employees buying on personal Amazon accounts or consumer platforms, Amazon Business channels that spend into a managed environment with analytics, approval controls and business pricing.
The limitation is that Amazon Business does not run competitive sourcing events. You see Amazon's prices — you cannot use the platform to solicit competitive bids from multiple suppliers. For commoditised goods with transparent market pricing, this is fine. For anything requiring competitive negotiation or custom specification, you need a different tool.
Fairmarkit wins on procurement discipline and savings generation. If your tail spend problem is that purchases under your competitive bidding threshold go un-competed, Fairmarkit solves that problem directly — it automatically generates RFQs, sends them to relevant suppliers, collects bids, analyses responses and recommends the award. Buyers manage by exception rather than transaction, enabling each FTE to handle 10x the event volume. The 11.4% average savings figure is consistently validated across customer case studies and represents real, measurable procurement value.
The trade-off is cost and implementation complexity. Fairmarkit is enterprise SaaS with enterprise pricing — it requires an integration project and organisational change management. It is not a plug-and-play solution for small teams or low-spend organisations. The ROI case needs to be built on the expected savings against subscription cost, which typically pencils out well for organisations with $50M+ in unmanaged tail spend.
