Why QT9 Outperforms ACE (PSC Software)

ACE is a highly configurable eQMS with a no-code workflow builder, but that flexibility comes with a trade-off — custom configuration and validation are typically billed as separate paid services, and pricing scales with the number of licenses. QT9 QMS provides a more accessible, cost-effective, and purpose-built alternative for organizations seeking a modern, scalable, out-of-the-box QMS.

Where QT9 has a competitive advantage over ACE:

No Extra Configuration or Validation Fees
QT9 QMS includes pre-built modules and validation support at no additional cost. ACE's configuration services and PQ validation are billed separately, with partner programs specifically offering discounts on these added fees.
Simpler, More Predictable Pricing
QT9 includes all modules, users, upgrades, and support in one subscription. ACE pricing varies by number of licenses and contract length, requiring a custom quote.
Larger, More Established User Base
QT9 QMS has 125 G2 reviews compared to ACE's 29, giving prospective buyers a broader base of verified customer feedback to evaluate.
Purpose-Built, Ready-to-Use Workflows
QT9 ships with pre-built processes for common QMS needs. ACE's no-code flexibility means most organizations build and validate their own workflows from the ground up, which can extend time-to-value.
Ideal Fit for SMB and Mid-Market Manufacturers
QT9 delivers enterprise-grade capability without enterprise-level complexity or costs, while ACE is most commonly adopted by life sciences startups and small-to-mid-size companies willing to invest in custom configuration.
Unified Support Included
QT9 provides unlimited support and free upgrades as part of every subscription, with no dependence on paid services for ongoing system changes.

"It is a one-stop shop for the QMS documents and quality records, and it is cost-effective due to concurrent licensing, which allows customers to need fewer licenses. All processes are straightforward and easy to implement, with a user-friendly interface. The software system is validated, and it has a great customer service support team.

"The added traceability of product compared to our current system is a fantastic improvement. Each module and/or feature is laid out the same for ease of use. The training modules and courses for each feature are easy to follow and match the system very well. In addition, customer support is very quick to respond and help with any issues.
