Share Invoices
Securely with Clients
Send PDF invoices, billing statements, and payment requests with password protection, auto-expiry, and download tracking — no email attachments needed. EU-hosted, free to use.
Built for Everyone Who Bills
Whether you invoice one client a month or hundreds, Comfyfile keeps your billing documents secure and professional.
Freelancers
Send invoices to multiple clients without cluttering inboxes. Password-protect billing documents and set expiry dates so sensitive figures don't linger online.
Accountants
Deliver financial statements, quarterly reports, and tax documents to business clients securely. Maintain a download record for your own audit trail.
Small Businesses
Share invoices with customers without a dedicated billing platform. Any file format works — PDF, Excel, or your accounting software's export.
Creative Agencies
Send project invoices to brand clients after campaign delivery. Keep billing data separate from creative assets and track when finance teams open them.
Consultants
Maintain professionalism with password-protected invoice links. Time-limited access ensures billing documents are reviewed promptly and not forwarded freely.
Contractors
Submit invoices to project managers and procurement teams with access controls. Know the moment your invoice is downloaded so you can follow up confidently.
Every Feature You Need
Send invoices with confidence. Know when clients access them, prevent unauthorized sharing, and keep sensitive billing data off public email threads.
Password Protection
Add a password to your invoice link before sending. Only clients with the correct passcode can access or download the file — keeping billing figures out of the wrong hands.
Auto-Expiring Links
Set a deadline for your invoice link — from 24 hours to several weeks. Once expired, the file is automatically and permanently deleted from our servers.
Download Tracking
See exactly when your client opened and downloaded the invoice. Eliminate 'I never received it' disputes with timestamped access logs you can refer back to.
Download Limits
Restrict how many times your invoice can be downloaded. Perfect for ensuring only the intended recipient accesses the file, not anyone the link is forwarded to.
Instant Delivery
No processing queues or wait times. Upload your invoice, get a shareable link immediately, and send it via email, Slack, WhatsApp, or any channel you use.
No Account for Recipients
Your clients simply click the link and download. No sign-up, no portal login, no friction. They get the invoice; you get peace of mind.
Share an Invoice in 3 Steps
No setup, no software to install. Just upload, secure, and share.
Upload Your Invoice
Drag and drop your PDF, Excel, or any invoice file. Comfyfile accepts all formats and processes uploads instantly — no size compression or quality loss.
Set Sharing Options
Add an optional password, choose an expiry window, and set a download limit. All optional — use as much or as little security as your situation requires.
Send the Secure Link
Copy the generated link and send it over email, Slack, WhatsApp, or any platform. Recipients click once and download directly — no account required.

Your Billing Data Stays Private
Invoices contain sensitive financial information. Comfyfile is built from the ground up to protect it.
Encrypted Transfer
Every invoice upload and download is protected with SSL/TLS encryption. Financial figures and billing data are never transmitted in plain text.
Zero Permanent Storage
Files are automatically deleted after expiry or when download limits are reached. Your invoice does not live on our servers indefinitely.
Access Control
Private ACL means invoice files are never publicly accessible. Every download is gated through a secure, token-based request.
EU Data Centers
All invoice data is stored exclusively in European data centers. Aligned with GDPR data residency expectations for businesses operating in the EU.
Download Analytics
View timestamps and download counts for every share. Maintain a lightweight audit record of when and how often your invoice was accessed.
No Email Attachment Risk
Invoices shared as Comfyfile links are not forwarded in email chains or indexed by email clients — reducing exposure compared to plain attachments.
Frequently Asked Questions
Everything you need to know about sharing invoices securely.
Can I share PDF invoices with Comfyfile?
Yes — PDF is fully supported, along with every other file format. Your accounting software's native export, Excel spreadsheets, Word documents, and image-based invoices all work without any conversion.
Do I need an account to share invoices?
No account is required. You can upload and share anonymously immediately. Creating a free account gives you access to share history, download analytics, and the ability to manage or revoke links after sending.
Do my clients need to register to download an invoice?
No. Your client simply clicks the link, enters the password if you set one, and downloads the file directly. There is no sign-up step on their end — making it genuinely frictionless.
How do I know when my client has downloaded the invoice?
Every share includes built-in download analytics. You can see the total download count and last access timestamp. With a free account, you get a full view of access history from your dashboard.
Is it safe to share invoices containing bank details or pricing?
Yes. All file transfers use SSL/TLS encryption, downloads are gated behind secure tokens, and files are stored with private ACL — meaning they are never publicly accessible. Adding a password provides a second layer of protection for particularly sensitive documents.
How long can an invoice link stay active?
You choose the expiry window at upload time — from 10 minutes to several weeks. For invoices, a window of 7–14 days is typically enough for the client to download while avoiding data lingering online indefinitely.
What happens if I send the wrong invoice?
With a free account you can manage and revoke active share links from your dashboard. Without an account, the safest option is to set a short expiry window when uploading — the link becomes inactive automatically.
Is Comfyfile suitable for GDPR-compliant invoice sharing?
Comfyfile is hosted in EU data centers and automatically deletes files after expiry or download limits — aligning with GDPR data minimisation principles. For formal compliance requirements, we recommend reviewing our privacy policy and terms and consulting your data protection officer.
