Meet the contenders
Karbon and Canopy are both established practice management software options, while Assembly focuses on the client experience, creating a single space where firms and clients can work together more efficiently.
Karbon: Best for internal workflow and collaboration
Karbon gives firms a central place to manage jobs, track progress, and coordinate team communication. Each client project sits in a Kanban-style board where tasks can be assigned, tracked, and commented on. Shared email visibility keeps conversations in one thread, while managers can monitor deadlines, capacity, and billing hours through reporting dashboards.
Pricing starts at $59 per user per month, billed annually. It’s reliable for team coordination, but firms often need separate tools for proposals, onboarding, and client chat.
Canopy: Best for client-facing accounting workflows
Canopy gives firms a central place to manage client relationships and organize work around billing, communication, and file sharing. It includes a built-in CRM for tracking client details, invoicing tools for payments, and document management for storing and sharing files. Its client portals for accounting firms let clients upload tax documents, sign forms, and pay invoices directly online.
Pricing starts at $45 per user per month for the small firm Starter plan, billed annually. Larger firms can choose modular plans starting at $150 per user per month, where CRM, billing, and workflow tools are sold separately.
Assembly: Best for unified client management after the sale
Assembly brings every part of client work into one place. We designed Assembly to help firms manage communication, contracts, payments, and collaboration inside a branded portal that clients actually use.
Clients can log in to sign engagement letters, pay invoices, upload files, and message your team securely in the same workspace. On the backend, staff can track client records, manage billing, and automate follow-ups without switching systems.
Plans start at $39 per month, including contracts with eSignatures and recurring billing. It’s a straightforward way to keep post-sale work organized and professional.
Karbon vs Canopy vs Assembly: Feature breakdown
Workflow and task management
Karbon: Karbon helps teams organize work through task lists, job templates, and progress boards. It’s strong for managing recurring jobs but struggles when workflows aren’t linear. Firms looking for Karbon alternatives often want more flexibility and client visibility in the same system.
Canopy: Canopy includes task tracking within its workflow module, letting users assign jobs, create subtasks, and link them to client records. It works well for small teams that want a light structure but can feel limited when several people collaborate on the same client file or need advanced automation.
Assembly: Assembly combines job tracking, communication, and files in one view so teams can stay aligned without extra tools. You can automate follow-ups, monitor deadlines, and connect each task to a client record for full visibility. It’s built to keep both internal work and client progress connected from start to finish.
Winner: Karbon. It wins for its detailed job templates, flexible task management, and strong visibility across large teams, making it ideal for firms that handle complex workflows.
Client communication and portals
Karbon: Karbon keeps communication internal through shared emails and comments. It’s useful for team alignment but lacks client messaging or real-time chat. Firms often add extra tools for client-facing conversations and file sharing.
Canopy: Canopy’s client portal allows clients to upload files, sign forms, and view invoices in one place. The experience is polished but limited to responding to firm requests. Clients can’t message proactively, which slows collaboration.
Assembly: Assembly brings both sides together. Clients can message your team, sign contracts, and pay invoices inside a branded, secure portal. Staff can reply instantly and view all updates in one workspace.
Winner: Assembly. It’s the only platform offering two-way client communication with a branded portal that combines billing, files, and chat.
Billing and payments
Karbon: Karbon includes time tracking and budget reports, but doesn’t support invoicing or online payments. Firms need separate accounting software for billing, which adds setup time and cost.
Canopy: Canopy provides built-in invoicing, online payments, and recurring billing for clients. It connects invoices directly to client records, making reconciliation easier. The modular pricing adds cost, but its billing tools are more advanced than Karbon’s or Assembly’s.
Assembly: Assembly includes invoicing, eSignatures, and subscription payments in the same client portal. It’s simple and effective for small teams, but lacks some detailed reporting features larger firms need.
Winner: Canopy. It offers built-in invoicing, online payments, and recurring billing that connect directly to client records.
CRM and client records
Karbon: Karbon tracks client details alongside projects and communication history. It’s helpful for active clients but doesn’t cover lead management or marketing workflows. Many firms use an external CRM for pre-sale tracking.
Canopy: Canopy includes a full CRM where firms can log client notes, track opportunities, and manage documents. It ties records directly to tasks, billing, and workflows, giving firms an end-to-end view of each client relationship.
Assembly: Assembly focuses on post-sale client relationships. Each record includes contracts, invoices, files, and communication history.
Winner: Canopy. It provides the most complete CRM, while Assembly shines in post-sale relationship management.
Pricing and scalability
Karbon: Karbon starts at $59 per user per month, billed annually. It includes core features but charges extra for advanced reporting and user add-ons.
Canopy: Canopy’s pricing starts at $45 per user per month for the Starter plan, but modular add-ons increase total cost.
Assembly: Assembly starts at $39 per month and includes all features such as contracts, billing, file sharing, and client messaging.
Winner: Assembly. It offers the clearest pricing and most complete package for the cost.
