Invoicing is costing you more than you think

Independent professionals lose an average of 6 hours per month on invoice creation, follow-up, and dispute resolution. That is billable time that never gets billed.

Hours lost to formatting

You copy-paste line items from emails, chase down hourly logs, and manually calculate taxes. Every invoice is a mini project you never charged for.

📱

Late payments drain momentum

Chasing overdue invoices is awkward and time-consuming. Each follow-up email interrupts your actual work and strains the client relationship you worked hard to build.

📋

Inconsistent presentation

Amateurish invoice design undermines the premium positioning you maintain through every other part of your client process. First impressions do not stop at the proposal.

🔍

Disputes from vague scope

Clients push back when the invoice does not clearly map to what was agreed. Without a clean itemized breakdown, you end up negotiating instead of getting paid.

Everything you need to invoice with confidence

Vellum handles the entire billing cycle from scope to payment so you can focus on the work itself.

Core

AI invoice generation from notes

Paste your project notes, email threads, or time logs and Vellum structures them into clean, itemized line items. No template hunting, no manual math, no Sunday evening admin sessions.

Core

Smart line item suggestions

The AI recognizes deliverable types -- design, development, strategy, revisions -- and suggests pricing ranges based on your history and industry benchmarks. You stay in control, but the defaults are smart.

Automation

Automated payment reminders

Set it once: Vellum sends polite, professionally worded follow-ups at 7, 14, and 28 days past due. No awkward emails from you. Payments just start arriving on schedule.

Presentation

Branded PDF output

Every invoice ships as a beautiful, brand-consistent PDF with your logo, colors, and payment terms. Clients open it and take it seriously from the first line item.

Speed

One-click from proposal

If you used ProposalAI to close the project, Vellum pulls the approved scope and rates directly. Your invoice is ready before you finish your morning coffee.

Tracking

Real-time payment dashboard

See at a glance which invoices are paid, pending, or overdue. A single dashboard replaces the spreadsheet you have been maintaining since 2019 and adding rows to at midnight.

Compliance

Tax and VAT line item support

Add tax rates by jurisdiction, apply them automatically to relevant line items, and export clean reports for your accountant at year-end. No more manual calculations or post-filing corrections.

Integrations

Connects to your existing stack

Sync with Stripe for online payments, Toggl for time tracking, and QuickBooks for accounting. Your entire billing workflow lives in one place rather than spread across five browser tabs.

From project notes to paid in three steps

Vellum is built for speed. Most users generate, review, and send their first invoice in under four minutes from sign-up.

1

Paste your notes

Drop in your project scope, time logs, or email threads. Vellum reads the context and identifies billable items, quantities, and rates without you lifting a finger. Plain language works fine.

2

Review and adjust

The AI drafts the invoice in seconds. You scan the line items, make any edits, apply your logo and brand colors, and confirm the payment terms. Most reviews take under two minutes.

3

Send and track

Dispatch the invoice with one click. Vellum handles delivery, read receipts, automated reminders, and payment confirmation. You get notified the moment money lands.

Professional billing without a billing department

Large agencies have finance teams, account managers, and billing software built into their overhead. You have Vellum -- and it is faster than all of them combined.

Whether you bill hourly, by project milestone, or on a monthly retainer, Vellum adapts to how you work rather than forcing you into a rigid template designed for someone else's business model.

  • Hourly, project, retainer, and milestone billing modes
  • Multi-currency support for international clients
  • Client portal so clients can view and pay without friction
  • Partial payment and deposit tracking built in
  • White-label PDF output on Professional and Agency plans

"I used to spend Sunday evenings piecing together invoices from Slack threads and Notion docs. Now I paste my notes in on Friday afternoon and the invoice is ready before I close my laptop. I have not had a late payment in three months."

"The automated reminders alone paid for the subscription on the first invoice cycle. I had one client who was chronically 45 days late. Vellum's follow-up sequence got him to 12 days. That is real cash flow for a solo operation."

"I run a three-person content agency. We were losing track of which invoices were out, which were paid, and which were overdue across 15 active clients. Vellum's dashboard fixed that in about ten minutes of setup. Genuinely shockingly good."

Common questions

Does Vellum take a cut of my payments?
No. Vellum charges a flat monthly subscription with no transaction fees or percentage cuts from your revenue. Stripe and ACH processing fees are standard Stripe rates, paid directly to Stripe and not to us.
How does the AI know what to charge for?
You paste in context: emails, project notes, a time log, or a bullet list of deliverables. The AI reads the text, identifies billable items and quantities, and structures them into line items. You review everything before the invoice goes out. Nothing is sent automatically without your explicit approval.
Can I fully customize the invoice design?
Yes. You upload your logo, set your brand colors, and choose your preferred layout. On the Professional and Agency plans, Vellum branding is completely removed from the PDF output so clients only see your business identity.
What happens when I hit the Solo plan limit?
You will receive an in-app notification as you approach the limit. You can upgrade to Professional at any time with prorated billing. There is no hard cutoff that prevents you from sending a critical invoice -- you will always have the option to upgrade before it blocks you.
Is my client data secure?
Vellum uses AES-256 encryption at rest and TLS 1.3 in transit. We do not sell or share client data with third parties. Invoice data is stored in isolated, encrypted databases with access logged and audited. SOC 2 Type II audit is in progress for Q3 2026.
Can I import existing invoices from FreshBooks, Wave, or HoneyBook?
Yes. Vellum supports CSV and PDF import from most major invoicing platforms. You can migrate your invoice history and client records without starting from scratch, and the AI will learn your rate patterns from the imported data.
