    The decision that matters

    Karmak Fusion joins heavy-duty service with dealer departments and centralized financial controls. Fullbay’s shop-focused purchase should be evaluated against the departments and locations you actually operate.

    Multi-location heavy-duty business

    Demonstrate shared customer records, inter-location parts and centralized financial reporting in the quoted Fusion modules and Fullbay configuration.

    Service-only repair shop

    Run parts ordering, technician time and customer approval through both. Ask which Fusion service tools are included without buying unrelated department modules.

    Questions for Karmak Fusion

    Compare the complete cost, not the starting price

    Compare user/location licensing, training, modules and extensions on matched quotes. Do not claim either product is cheaper from a Fullbay starting price and an unknown DMS quote.

    Use the same job in both demonstrations

    1. Create a representative unit and repair, including mileage/engine hours where relevant, inspection photos and an estimate revision.
    2. Assign two technicians, issue an in-stock part, order a missing part and capture labor across more than one day.
    3. Obtain a sample customer authorization, complete an invoice and reconcile the payment or fleet statement without sending a live request.
    4. Export the completed history and an open repair. Confirm attachments, accounting totals, permissions and contract exit terms.

    Frequently asked

    Is Fullbay better than Karmak Fusion?

    It depends on your shop. Fullbay (Heavy-duty truck shop management software) and Karmak Fusion (Heavy-duty dealer and service DMS) serve different needs. Confirm current pricing and features with each vendor; Repairius does not verify third-party prices.

    Can I use Repairius alongside Fullbay or Karmak Fusion?

    You can keep other services while using Repairius. Repairius offers a free basic listing and website with booking requests; advanced management tools require the appropriate paid plan. This does not imply an integration with either vendor or guarantee inquiry volume.

    Can I replace both with one tool?

    It depends on what you use each one for. Repairius combines a free directory listing with booking requests and, on a paid plan, dispatch, estimates and invoicing. Some shops keep Fullbay or Karmak Fusion alongside Repairius — compare your current contracts before cancelling anything.
