Why Privacy Matters for Vendor Agreements

Vendor agreements typically contain commercially sensitive information: pricing and discount structures, payment terms, exclusivity clauses, intellectual property rights, and confidentiality obligations. When you upload such a document to a cloud-based signing platform, a copy of that agreement sits on a third-party server — potentially accessible to their staff, subject to their data retention policies, and exposed to any future security incidents.

SigPDF processes your vendor agreement entirely inside your browser. The PDF is read locally using JavaScript, your signature is embedded directly into the document on your device, and the signed file is downloaded to your computer. At no point does the document travel over the internet to any server.

What a Vendor Agreement Typically Covers

  • Pricing and payment terms — Unit prices, volume discounts, invoicing schedule, and payment due dates
  • Delivery and lead times — Expected delivery schedules and consequences for late delivery
  • Quality standards — Specifications, testing requirements, and rejection procedures
  • Confidentiality — Mutual obligations to keep commercial terms and trade secrets private
  • Term and termination — Contract duration and the conditions under which either party may end the agreement
  • Dispute resolution — How disagreements will be handled, including jurisdiction and governing law
