Esker Source-to-Pay review
A broad source-to-pay suite with strong SAP connectivity and contact-sales pricing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Esker Source-to-Pay is a cloud platform for procurement, finance, accounts payable and IT teams managing supplier processes across business units, locations and ERP environments. It connects sourcing events, supplier evaluation, onboarding, contract management, guided purchasing, approvals, invoice processing, payment coordination and analytics. The suite also supports supplier self-service, invoice-status visibility and mobile access for workflow reviews and approvals. Organizations looking for source-to-pay coverage across the full supplier lifecycle will find a broad functional scope here.
Its strongest fit is with SAP-connected organizations. The product lists connectivity with SAP ECC and SAP S/4HANA, while also identifying multi-ERP connectivity as a capability. Core procure-to-pay controls include policy-based approval workflows, receiving workflows, purchase order, receipt and invoice matching, and supplier portal access. Contract renewal and obligation tracking extend coverage beyond transactional purchasing, helping teams manage supplier relationships and commitments within the same suite. The web platform and mobile workflow access support users across procurement, finance and accounts payable operations.
Pricing follows a contact-sales model, so buyers should expect a sales-led evaluation rather than a published tier comparison. The published capabilities emphasize AI-assisted invoice data extraction and validation, supplier information management, approval routing and three-way matching. Esker Source-to-Pay is a strong candidate for organizations that want one platform spanning sourcing through payment, particularly where SAP connectivity and cross-business-unit process control matter. Teams seeking transparent self-serve pricing, a non-SAP-centered integration starting point or a desktop-native product may prefer another option.
