It removes all barriers to getting started and provides instant value.
Professional and Modern Template Library
Gone are the days of ugly, outdated invoice formats. Invoice Sonic provides a library of clean, modern, and professionally designed invoice templates suitable for any industry. Whether you need a standard invoice, a proforma invoice for quotes, or a blank template to fully customize, you can choose a layout that perfectly reflects your brand's professionalism and style.
Instant PDF Download and Sharing
Once your invoice is crafted, you don't have to wait or jump through hoops to use it. With a single click, Invoice Sonic generates a polished PDF version of your invoice, ready for download. This PDF includes all your details, line items, totals, and the Invoice Sonic branding, presenting a completely professional document that you can instantly email to clients or print for your records.
Automated Calculations and Customization
The tool automatically handles all the math for you, calculating subtotals, taxes (like GST), and final totals as you add or edit line items. This eliminates manual errors. Simultaneously, it offers deep customization: you can add your business name, logo, client details, specific payment terms, due dates, and itemized descriptions with quantities and prices, making each invoice uniquely yours.
Vendor Space
Comprehensive Vendor & Sponsor Management
Vendor Space replaces scattered spreadsheets and separate systems by housing all your vendors and sponsors in one unified dashboard. You can review applications, track statuses (like Confirmed, Pending, or Waitlist), and manage all communication and details for every participant. Sponsor management is built directly into the platform, allowing you to create tiered sponsorship packages, track deliverables, and manage those important relationships alongside your regular vendor data, eliminating the need for a separate tracking system.
Interactive Visual Booth Mapping
Say goodbye to confusing grid charts. Vendor Space provides interactive, visual floor plans where you can drag and drop vendors into specific booth spaces. The map shows real-time availability with clear color-coding for taken, reserved, premium, and available spots. This feature automatically helps prevent double-bookings and gives you and your vendors a crystal-clear picture of the event layout, making assignment and planning a visual and simple process.
Integrated Payments & Digital Contracts
Streamline your financial and legal workflows completely. The platform integrates with Stripe (and soon Square) to collect payments securely and directly from vendors through a self-serve portal. You get real-time tracking of all revenue. Simultaneously, you can send, sign, and track legally-binding digital contracts and agreements with built-in e-signature capabilities, keeping all documentation organized and easily accessible in one place.
Self-Serve Vendor Portal & Analytics
Vendor Space provides a dedicated, professional portal for your vendors. They can discover your event, submit applications, upload documents, make payments, and manage their own details without back-and-forth emails. For you, the analytics dashboard offers real-time insights into key metrics like total revenue, booth fill rates, vendor participation stats, and sponsor progress, giving you the data you need to measure success and make informed decisions.

The Freelancer Sending a First Invoice
A graphic designer just landed their first client project. They need to send an invoice quickly to look legitimate and get paid.

The Small Business Managing Client Billing

The sponsor management module is perfect for securing and managing partnerships with local breweries or brands.
Conferences and Trade Shows
Conference organizers can leverage Vendor Space to manage both exhibitors and sponsors professionally. The platform handles custom booth pricing for different package tiers, manages contract signing for large sponsors, and provides a clean portal for exhibitors to register and access event information. The analytics help track exhibition hall sales and sponsor fulfillment leading up to the event.
Fundraising Galas and Non-Profit Events
Non-profits running galas, auctions, or charity fairs benefit from the cost-effective, pay-as-you-go model.
