What CAL Business Solutions does
CAL Business Solutions, Inc. (formerly Computer Associates Limited) is a privately held ERP value-added reseller (VAR) headquartered in Harwinton, Connecticut. Founded in 1982 by George Mackiewicz, the company has operated for more than 40 years as an implementation, customization, and support partner for small and mid-market companies across the United States, reporting more than 750 cumulative customer engagements and 300+ specialized projects.
The company's core product portfolio consists of three third-party ERP platforms resold and supported: Acumatica Cloud ERP, Microsoft Dynamics 365 Business Central, and Microsoft Dynamics GP, plus the Cavallo (formerly SalesPad) distribution add-on for Dynamics GP. CAL is a Microsoft Gold Certified Partner (since the early 2000s following Microsoft's acquisition of Great Plains) and an Acumatica GOLD Certified Partner (achieved in 2017 within six months of adding the product). The company operates an in-house development team that performs customizations and integrations - a capability it explicitly differentiates around - and delivers services spanning implementation, data migration from systems such as QuickBooks/Sage/SAP, third-party integration, training, and ongoing multi-channel support (on-site, telephone, secure remote).
Revenue mechanics combine project-based professional services (implementation, customization, training, integration) with recurring support contracts. Customer segments are diversified across at least ten verticals, with distribution, manufacturing, professional services, and non-profit organizations identified as primary. Sales are delivered through a consultative direct sales motion with discovery calls and dedicated sales contacts. In 2024, founder George Mackiewicz transitioned ownership to internal principal owners Stacey Poll and John DiLeo, signaling a continuity strategy rather than a sale or restructuring event.

CAL Business Solutions competitors and assessment
Company assessmentDirect peers
- SWK Technologies: SWK Technologies is a U.S. ERP value-added reseller and implementation partner specializing in Acumatica, Sage, and other mid-market ERP platforms, with comparable product breadth (cloud ERP reselling, customization, and support) to CAL Business Solutions.
- Boyer & Associates: Boyer & Associates is a Microsoft Dynamics ERP/CRM VAR providing implementation and support services for Dynamics GP and Dynamics 365 Business Central, directly competing with CAL on Microsoft Dynamics products and mid-market customers.
- Rand Group: Rand Group is a Microsoft Dynamics ERP and CRM partner offering Acumatica and Dynamics 365 implementations with a comparable SMB/mid-market focus, similar vertical practice areas (distribution, manufacturing), and overlapping customer base with CAL.

- Cavallo (SalesPad): Cavallo (formerly SalesPad) is the distribution-focused ISV whose add-on CAL resells. As a flagship partner with 70+ implementations, CAL is one of Cavallo's go-to implementation partners — and other Cavallo partners compete with CAL for distribution ERP projects.
Broad incumbents

- Microsoft (Dynamics 365): Microsoft Dynamics 365 is a core vendor partner of CAL's but also a broad incumbent in the ERP market. Microsoft's direct sales motion and partner ecosystem set the competitive landscape that CAL operates within as a Gold Certified VAR.
- Acumatica: Acumatica is the cloud ERP vendor whose product CAL resells and implements as a GOLD Certified Partner. Acumatica's direct sales expansion and partner program economics directly influence CAL's go-to-market.
