Can I include payment stubs or remittance slips?

Yes. Upload your invoice PDF exactly as you want it printed. If your invoice includes a detachable payment stub at the bottom, it will print that way. We print your document exactly as uploaded on standard 8.5x11 paper.

Do you support bulk invoice mailing?

Yes. You can upload and send invoices one at a time or in batches. Each invoice is a separate mail piece with its own status history. USPS scan updates appear when available. Volume pricing is not currently available, so each invoice uses standard per-piece pricing.

What's the cost for a typical 2-page invoice?

A 2-page black & white invoice costs $1.70 ($1.50 for the first page + $0.20 for the second page), plus a small platform fee. Color invoices are $2.15. View our full pricing page for details.

Is there a discount for monthly volume?

No. Volume pricing is not currently available. Every invoice uses standard per-piece pricing regardless of monthly volume.

How long does delivery take?

We process orders the same day, print the next business day, and mail the day after. Most letters arrive within 1–5 business days.

Can my team review each invoice's mail history?

Yes. The dashboard keeps processing history and available carrier events for each invoice. Email notifications reflect status changes as they arrive.

Is my financial data secure?

Absolutely. Your documents are encrypted in transit and at rest. Files are processed automatically by our printing system - no human ever sees the content. Documents are permanently deleted within 7 days of printing.
