Key Features of Flowlu's Free Document Collaboration

Flowlu provides a robust set of tools designed to streamline how your team handles both static files and dynamic financial documents. From detailed internal wikis to client-ready quotes, our platform ensures your collaborative workspace is efficient and organized.

Collaborative Invoicing & Estimates

Stop emailing the same client quote back and forth between changes. Collaborate on estimates and invoices in the cloud. Users can add or remove line items, edit prices, and apply discounts or other adjustments before the document is finalized. Convert estimates to invoices with a click for speed.

Internal Knowledge Base

Assemble a complete hub for your internal documents; store SOPs, operating guidelines, and any other information in an internal knowledge base free forever. You can also test external knowledge bases by starting a free trial, which allows you to publish documentation publicly, and upgrade to paid plans when ready.

Cloud Storage & Team Access

Keep your business documentation secure in the cloud and give immediate access to your team. The Free plan allows for two users to work in Flowlu collaboratively with a 100MB limit on file storage and simplified login access with a Google account. More space available on paid plans.

Comments & Feedback Tools

Streamline the free document collaboration by using built-in comments and mentions directly on financial documents (estimates, invoices). If you need assistance or guidance, simply tag an approver in the comments section of the record.

Secure Sharing & Permissions

Control exactly who sees your sensitive business data with flexible access rights. You can grant specific team members access to view or edit financial documents while keeping other areas restricted. Flowlu secures confidential data while allowing for the best document collaboration online.

Visual Planning with Mind Maps

Before you start writing, collaborate on the strategy. Present your ideas with mind maps to put document structures together. Use robust tools for effective co-authoring of project outlines and brainstorming sessions.

Client Portal & External Collaboration

You can take collaboration even further with Client Portals. Available during your free trial, this feature gives your clients a dedicated space to view invoices, approve estimates, track project progress, and send feedback.

Workflow Automation

Save time on repetitive administrative work. Available to test during your trial, Flowlu’s Automations can handle your document logistics—such as automatically sending invoice reminders to clients or creating follow-up tasks for your team when an estimate is approved.

Popular Use Cases for Free Collaboration

Marketing: Content Teamwork & Planning

Marketers use the collaborative workspace to work on campaign strategies and organize content calendars. Post drafts can be stored in a shared internal knowledge base, where writers and editors can exchange feedback through comments to tune messaging. This keeps creative assets central and accessible to all.

Sales: Co-authoring Estimates & Quotes

Sales teams can use the collaborative workspace to draft precise proposals. A sales representative can start an estimate, while a technical lead reviews the scope and pricing via comments. Linked with the built-in CRM (100 contacts included), you can attach these documents directly to client records.

HR & Admin: Policy Management & Contracts

Even small teams need clear guidelines. Use the internal knowledge base to co-author and store your company handbook, freelancer agreements, and operational policies. This ensures that your foundational business documents are organized, secure, and ready to share as your business scales.

Freelancing: Client Project Management

Freelancers can manage the entire document lifecycle for a client in one place. Start by collaborating on an estimate, turn it into an active project with tasks, and finally convert it into an invoice when the work is done.
