ClientWin OS vs Handoff

ClientWin OS is web-based AI proposal software for freelancers, solo consultants, small agencies and other service providers. Its workflow checks opportunity fit, guides pricing, matches relevant proof, drafts a proposal, shares a Client Deal Room link and tracks responses and outcomes. Users review and send every proposal themselves; the product says it does not scrape platforms or submit proposals automatically. The Free plan is billed at $0 per month and includes one proposal generation, five AI Actions, three manual Proof Vault items and basic PDF or share export. Starter costs $13 a month, Pro costs $26 a month and Agency costs $68 a month. Paid plans increase monthly allowances and add capabilities such as proof import, branded exports, client rooms, automated workflow and team collaboration. Proposal generations and AI Actions have separate allowances; automated workflow on Pro and Agency uses those same allowances. Private workspace data is not used to train public AI models, though relevant data may be sent to third-party AI providers. Platform Intelligence is off by default.

Handoff is software for residential construction businesses that supports estimating, project management and administrative work. It generates estimates and proposals from scopes, blueprints, job photos and site walkthroughs; uploaded drawings, photos and other files can also provide details such as square footage, quantities and material lists. Project tools include AI scheduling, daily logs, alerts, photo and file management, client portals and change orders. Financial workflows cover invoicing, payments, milestone-based billing, custom pricing and markup, and consumer financing. Named integrations include QuickBooks Online, Google Calendar, Magicplan and Zapier; estimates, invoices and payments can sync with QuickBooks Online. The REST API supports webhooks and syncing projects, estimates, proposals, invoices and contacts, and is available on Scale. Handoff lists web, mobile and desktop access, with apps for iOS, Android and desktop. Flex costs $119 a month billed annually and includes 50 AI usage credits per month, one custom pricing catalog and two users. The seven-day free trial does not require a credit card.
