| Description | Accelo is a cloud-based professional services automation (PSA) platform that connects sales, projects, client communications, time tracking, and billing on one system. It's built for professional services firms—consultancies, marketing and creative agencies, IT services providers, engineers, and accountants—typically small-to-midsize teams that want end-to-end visibility from first opportunity to final invoice. Its main differentiator is automatically updating client records and workflows from everyday interactions, letting a whole services business run on a single connected platform rather than stitching together separate CRM, PM, and invoicing tools. | SleekFlow is an omnichannel conversation platform that brings WhatsApp and other messaging channels into one team inbox. It adds AI agents, broadcast campaigns, an automation flow builder and a social CRM for sales, marketing and support teams. Plans are priced per month with included monthly active contacts and user seats. Essential starts at US$49 a month (US$588 billed yearly), Pro is US$109, Premium is US$279 and Enterprise is custom. There is no free plan, but a 7-day free trial of the Pro plan is offered with no credit card required. |
