Manual processes, disconnected tools, and low supplier engagement can delay awards, introduce legal risk, and drive up costs. If you’re managing RFxs through spreadsheets or juggling disconnected systems, you’re not just losing time—you’re increasing risk.

Exostar’s source-to-contract (S2C) gives your procurement team a smarter, more secure way to manage supplier sourcing and selection. From initial RFIs to contract award, you can streamline every step, ensure compliance with ITAR, EAR, and DFARS regulations, and drive greater supplier participation—all in one centralized workspace.

Source-to-contract is the upstream aspect of the procurement process. It covers everything from identifying sourcing needs to finalizing supplier contracts, including spend analysis, supplier identification, RFx management, negotiation, and contract execution.
The source-to-contract process typically follows five stages:
Source-to-contract software tools streamline these steps by replacing manual spreadsheets with centralized platforms that standardize workflows and maintain audit trails.
Source-to-contract covers strategic activities related to finding and contracting with suppliers. Procure-to-pay (P2P), in contrast, handles downstream, transactional processes: purchase orders, goods receipt, invoicing, and payment. S2C ends when the contract is signed; P2P begins when orders are placed.

Built-in ITAR, EAR, and DFARS safeguards automate compliance, and centralized visibility provides real-time tracking and audit-ready records.
