About
That's The One is an all-in-one wedding planning software designed specifically for professional wedding planners and event coordinators. The platform eliminates the need for multiple disconnected tools by bringing every aspect of event management under a single subscription — fully customizable with the planner's own branding, logo, and color scheme. On the guest management side, TTO offers advanced guestlist building, custom RSVP forms, dietary and travel detail collection, digital save-the-dates and e-cards, and bespoke event websites with custom URLs. For operational planning, it includes a Vendor CRM for storing contracts and invoices, drag-and-drop floor and seating chart design, multi-currency payment and budget tracking, event timelines, a to-do task tracker with team assignments, and real-time collaborative comments supporting text, voice, and video messages. TTO is designed with both the planner and client in mind — clients get a polished, branded experience while planners maintain a single source of truth. It supports multi-language and multi-currency configurations, making it especially powerful for destination weddings and international events. Rated 4.9 by professional planners, TTO is trusted by industry leaders and boutique firms alike. A 30-day free trial is available with no commitments required.

Pros
- True All-in-One Platform: Replaces a fragmented stack of tools (spreadsheets, separate CRMs, seating apps) with a single subscription, saving time and reducing costs.
- Full White-Label Customization: Planners can present the platform entirely under their own brand, elevating the client experience and reinforcing their professional identity.
- Global Accessibility: Multi-language support and all-currency budget tracking make TTO ideal for destination weddings and internationally-based planning firms.
- Flat Pricing for Unlimited Events: One subscription covers unlimited events and all features — no per-event charges or feature gates that penalize growth.
Cons
- Niche Use Case: The platform is purpose-built for weddings and events, making it unsuitable for general project management or non-event businesses.
- Subscription Required After Trial: After the 30-day free trial, continued access requires a paid subscription, which may not suit occasional or hobbyist planners.
- Web-Only Access: No dedicated native mobile apps are prominently advertised, which may limit on-site usability for planners working in the field.
