Handoff vs ProposalGrid

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.

ProposalGrid creates AI-assisted proposals and quotes, shares them as branded links, tracks client decisions and turns accepted work into print-ready invoices. Its AI can draft a proposal from a website or job description, including scope, deliverables, timeline and pricing; users can edit or regenerate individual blocks. A block editor supports headings, rich text, images and tables, and recalculates line items, quantities and totals automatically. Contacts can be imported from HubSpot, Pipedrive, Zoho, Salesforce, Excel or CSV exports. Each stakeholder can receive an individual link to a live branded proposal, with view tracking. Clients can accept online or request changes, and signatures may be typed or hand-drawn, with consent, timestamped audit trails, IP logging and tamper-evident content hashes. Optional reminders can follow up on undecided proposals or warn before expiration. Accepted proposals can become branded invoices, including on the free plan. The browser-based service supports client-facing materials in English or Lithuanian. Free allows five active documents and two AI drafts monthly; Pro costs €19 a month.
