Swell Systems Inc is the SaaS company behind SWELLEnterprise, the all-in-one client management platform purpose-built for service businesses, agencies, and consultancies. Founded in 2017 in Wilmington, NC, the company unifies CRM, project management, invoicing, proposals, embeddable forms, scheduling, helpdesk, and a fully branded client portal into a single workspace — with a built-in AI assistant and a true white-label/reseller tier (Business plan, $199/mo). The open REST API exposes 45+ endpoints and 30+ webhook events, letting agencies and growing teams build the workflow they actually want without bolting on multiple point tools. Best fit: marketing and design agencies, consulting firms, photographers, coaches, real estate teams, legal practices, and any service business that bills on a project, retainer, or recurring basis.
