Frequently asked questions
What is source-to-pay software?
Source-to-pay software connects the processes involved in selecting, onboarding, contracting, buying from, invoicing and paying suppliers. It gives procurement and finance teams one environment to improve visibility, control and collaboration across the supplier lifecycle.
What processes are included in source-to-pay?
A complete source-to-pay approach typically covers supplier management, sourcing, contract management, procurement, invoice processing, payments and the shared data and controls that connect them.
What is the difference between source-to-pay and procure-to-pay?
Procure-to-pay usually starts when a purchase is requested or ordered. Source-to-pay begins earlier, with supplier selection, qualification and contracting, giving organisations a broader view of spend, supplier risk and buying performance.
How does source-to-pay software improve spend control and working capital?
By connecting supplier, contract, purchasing, invoice and payment data, source-to-pay software helps teams control off-process spend, enforce policy, improve visibility into commitments and make better decisions about payment timing and cash out.
How does Esker connect procurement and finance in one platform?
Esker brings sourcing, supplier management, contracts, procurement, accounts payable and payments together in one coordinated environment so teams can share data, automate workflows and act with more consistency across the full supplier lifecycle.
What should enterprises look for in a multi-ERP source-to-pay platform?
Enterprises should look for flexible integration, support for complex organisational structures, strong governance and security, scalable workflows, and the ability to expand across processes over time without creating new silos.
