Marketplace Sellers
Marketplace sellers operate on Amazon, eBay, Etsy, and similar platforms where commission structures, advertising costs, and fulfilment fees can erode margins quickly. Profitability often depends on listing optimisation and fee management rather than product quality alone.
What we'd investigate
We don't guarantee results in every area. We investigate each one systematically — and only invoice from what we can actually verify.
E-commerce platforms and hosting contracts are often set at launch and rarely benchmarked. We compare your current terms against market rates and flag where renegotiation may reduce cost.
Fulfilment and shipping costs accumulate when carrier contracts and warehouse agreements go unreviewed. We benchmark your logistics spend and identify where terms can be improved.
Payment gateway fees and processing rates vary significantly across providers. We review your transaction costs and identify where savings may be available through renegotiation or switching.
Returns processing and refund handling create hidden operational costs. We map each step of your returns workflow and identify where automation or policy changes can reduce cost.
Customer acquisition budgets across e-commerce businesses are often fragmented across channels. We analyse spend by channel and identify where budget may be consolidated for better ROI.
Inventory carrying costs and warehousing agreements accumulate when stock levels and storage terms drift from optimal. We review your inventory spend and flag where improvements may sit.
Customer service costs grow as order volumes increase without proportional efficiency gains. We investigate which support tasks can be partially automated to reduce manual overhead.
SaaS tools, plugins, and integration costs accumulate across e-commerce operations. We review your technology stack and identify where consolidation or renegotiation may reduce spend.

Use cases and capabilities — important notice. The use cases, needs, and capabilities described on this website are illustrative examples of areas where AI and automation may be able to add value. They are not representations, warranties, or guarantees that any specific outcome, saving, or improvement will be achievable for any particular client. The applicability of any use case depends on the client's specific IT infrastructure, data architecture, operational processes, workforce arrangements, contractual obligations, and regulatory environment. Coaley Peak will assess compatibility — including system integrations, data handling requirements, and human and technical constraints — during the scoping and audit process before any engagement begins. No work will commence on a specific use case until its feasibility has been assessed and agreed in writing. Nothing on this website constitutes advice, a representation, or a commitment in relation to any specific use case or technology. Descriptions of approaches, methods, and techniques are general in nature; Coaley Peak makes no representation as to whether any specific implementation may be subject to third-party intellectual property rights — including patents — and clients are responsible for obtaining independent legal advice where required. Where use cases reference regulated activities — including but not limited to anti-money laundering, FCA-regulated functions, KYC, data protection compliance, employment law, or sector-specific regulatory obligations — implementation does not reduce, replace, or discharge any statutory or regulatory duty incumbent on the client, and clients remain solely responsible for compliance with all applicable regulatory requirements. Data handling capabilities are subject to the client's infrastructure, applicable data protection legislation (including UK GDPR), and the terms of any data processing agreement in force between the parties.

Pay on results — eligibility notice. Results-based pricing applies exclusively to commercial contracts signed on or after 24 March 2026. All engagements entered into before this date — including any subsequent renewals — are not subject to pay on results terms and are governed solely by the pricing structure in the original agreement, unless a separate written addendum specifically incorporating pay on results terms has been executed by both parties. All pay on results contracts carry a document reference beginning contract_payonresults. If you are unsure which terms apply to your engagement, please contact legal@coaleypeak.co.uk.
All claims on this page are general descriptions of Coaley Peak's service model and are not guarantees of specific outcomes. Results vary by business, cost base, and baseline efficiency. "No upfront cost" refers to the pay-on-results pricing model; ancillary costs (e.g. third-party integrations) may apply and are disclosed before engagement. Independent verification is funded by Coaley Peak and conducted by a qualified professional who is not an employee of Coaley Peak. The "30 days' notice" exit term applies to standard commercial contracts; bespoke terms may differ. See our Terms & Conditions, Guarantee, and Independent Verification pages for full details.
