Fergus may hit limits when large multi-branch contractors needing SimPRO depth of asset management and project complexity, or sole traders where simpler tools like ServiceM8 provide sufficient features. Wave may hit limits when Australian businesses needing GST, BAS, or STP compliance, or any business requiring inventory management, project tracking, or extensive third-party integrations. Both platforms are designed to grow with your business, but scaling experience varies. Fergus connects with 37+ tools, and Wave with 33+, so integration flexibility at scale is comparable. Clever Ops helps mid-market Australian businesses plan their tech stack for growth, not just for today.

Since Fergus (industry tools) and Wave (accounting & finance) serve different functions, many businesses run both. The key is connecting them so data flows automatically. Clever Ops builds these integrations, keeping invoices in sync across both platforms.

Full onboarding for either Fergus or Wave, including configuration, data import, and team training, typically takes 4-8 weeks with Clever Ops support. Self-service onboarding can take longer and often results in suboptimal configurations that limit the platform's value.
