Amazon Web Services (AWS)

Pros

• The service catalogue is unusually broad, with over 200 services across 38 regions, so most infrastructure needs can be met on one platform.
• EC2 has a 99.99% region-level SLA with credits of up to 100%, and instances unavailable for more than six minutes in an hour are not billed for that hour.
• The free plan gives up to $200 in credits, and more than 30 always-free services let new teams experiment at low cost.
• Support scales from a $29 minimum up to dedicated Enterprise and Unified Operations tiers for mission-critical workloads.
• G2 rates it 4.4 across more than 17,000 reviews, and reviewers praise its scalability and global reach.

Cons

• Reviewers widely cite a steep learning curve across the console and services.
• Usage pricing is complex and can produce unexpected bills unless spend is monitored closely.
• Paid support is billed as a percentage of total AWS spend, so support costs rise with usage.
• A July 2025 billing console bug showed customers estimated charges in the billions, which hurt trust in its cost tooling.

Klient PSA

Pros

• It runs natively in Salesforce, so project, resource and billing data sit next to CRM opportunities and use the existing Salesforce permissions.
• Reviewers say time tracking, project profitability and forecasting work well together in one system.
• The base edition includes the Salesforce Platform license and connectors for QuickBooks, Xero and AccountingSeed.
• Klient lists SOC 2 Type 2 compliance, and its agents inherit Salesforce's Einstein Trust Layer.
• Enterprise includes a branded client portal with approvals and five community users per internal user.

Cons

• It only makes sense for firms already on Salesforce.
• Reviewers mention a steep learning curve and thin documentation.
• Some users call the project management weaker than in dedicated PM tools, and one finds revenue recognition weaker than competitors'.
• Jira Sync, the Sage Intacct connector, AI agents and guided onboarding are all extra costs, and guided onboarding can reach $18,000.
• Reviewers say there is no customizable PDF generation for proposals.
