FreshBooks Invoicing represents the core strength of the FreshBooks platform — invoice creation, delivery, and collection tools built specifically for the needs of service businesses and self-employed professionals. Invoices are generated from professional, fully customizable templates with logo, color scheme, and payment terms configured per client or globally. Automatic late payment reminders send at user-defined intervals without manual scheduling, significantly reducing follow-up effort on overdue accounts. Recurring invoice schedules handle monthly retainers, subscription services, and regular project billing with automatic generation and delivery. Online payment acceptance via credit card and ACH is embedded directly in invoice emails, enabling one-click payment from the client's perspective. The client portal provides a branded experience where customers can view all invoices, make payments, and track project communication. FreshBooks' time tracking integrates seamlessly — billable hours convert to invoice line items in seconds. Expense lines can be marked as billable and attached to client invoices. Estimates and proposals convert to invoices upon acceptance, creating a clean workflow from quote to collection. Late fees can be configured to apply automatically after a specified grace period. For service businesses, FreshBooks Invoicing's combination of professional aesthetics, automation, and client experience is among the strongest available at its price point.

AND.CO was a popular freelance business management platform for independent contractors, offering contracts, invoicing, time tracking, and expense management in a clean, approachable interface. Following Fiverr's acquisition, AND.CO was rebranded as Fiverr Workspace, expanding its reach through Fiverr's large freelancer community while maintaining the core functionality that made AND.CO a favorite among solopreneurs. The platform's contract builder uses legally vetted templates across common freelance service categories — design, writing, development, consulting — and enables e-signature collection without additional tool costs. Invoices can be tied directly to signed contracts, ensuring billing matches agreed scope. Automatic payment reminders reduce manual follow-up. Stripe and PayPal integrations handle online payment acceptance. Time tracking logs billable hours per project and converts them to invoices with a single action. Expense tracking with receipt capture links costs to specific client projects. The free tier covers basic invoicing and contracts with Fiverr Workspace branding; the Pro plan removes limitations and adds white-labeling for a professional client presentation. For Fiverr freelancers, the integration with their existing Fiverr account and marketplace activity provides a natural entry point. For non-Fiverr freelancers, Workspace competes effectively against Bonsai and HoneyBook, particularly for users who prioritize clean design and ease of use over comprehensive feature depth.
