Statement of Work Template for E-commerce Businesses (UK 2025)

Last updated: February 2025

Why E-commerce Businesses Need a Statement of Work

E-commerce statements of work define specific platform builds, marketplace integrations, or fulfilment system implementations. These must address the complexity of integrating multiple systems including payment gateways, inventory management, shipping providers, and marketing platforms. The SOW must specify how the e-commerce system will handle transaction volumes, define performance requirements for page load times and checkout completion rates, and establish clear go-live criteria and post-launch support.

Key Clauses for E-commerce

  • Platform integration specifications and API requirements
  • Performance benchmarks for load times and transaction handling
  • Go-live criteria and launch checklist
  • Post-launch support period and bug fix obligations

Common Mistakes

  • Not specifying performance requirements for peak traffic scenarios, leading to crashes during high-volume trading
  • Failing to define comprehensive go-live criteria, resulting in premature launches with critical functionality gaps

Template Sections

  • Integration specifications and API documentation requirements
  • Performance benchmarks and load testing criteria
  • Go-live checklist and post-launch support

FAQ

What performance benchmarks should an e-commerce SOW specify?

Include page load time targets under 3 seconds, checkout completion time targets, concurrent user handling capacity at peak levels, API response times for integrations, and uptime requirements during trading hours. Specify how performance will be tested, including load testing at 150% of projected peak traffic, and what remedies apply if benchmarks are not met.

How should an e-commerce SOW handle the go-live process?

Define a detailed go-live checklist covering functionality testing, payment processing verification, stock sync confirmation, SEO redirect mapping, and analytics tracking setup. Include a pre-launch staging period, a defined go-live window with rollback procedures, and a post-launch hypercare period of typically 2-4 weeks with enhanced support availability.
