An invoice mailing service for customers who still want paper

Each invoice gets a status page in your Postmarkr dashboard, with USPS scan updates when available. We email you when it's sent to print, and you can download a PDF of exactly what we printed. Mail returned as undeliverable because of an incorrect or incomplete address is not eligible for a refund or free resend. If USPS confirms a letter was lost, we'll resend it for free.

Postmarkr's invoice mailing service costs $2.05 for a one-page invoice in black and white, $2.26 for two pages and $2.47 for three; color is $2.52 for one page. Each total includes printing, the envelope, the address page, USPS First-Class postage and the processing fee. No plan or minimum; you pay per invoice by card.

Yes, as a PDF. Export each invoice from QuickBooks, Xero, FreshBooks or Wave and upload it to Postmarkr. There's no accounting-software connection or API yet, and a combined export isn't split into separate letters, so save one PDF per invoice. Then mark it as sent in your accounts receivable records.

No. Postmarkr adds an address page in front with your customer's address and yours, and it shows through the #10 envelope's windows. Your invoice prints exactly as you made it, behind that page. The address page is in your preview and every total, billed as one extra page.

Printed the next business day following payment. Your letter enters the mailstream by the next business day. From there, USPS estimates 1–5 days for First-Class delivery. On net 30 terms, count back from the due date and allow for the check's trip back.

Two ways. For different invoices or itemized monthly statements, export each as its own PDF, add it to your Cart with its customer and pay for up to 10 per checkout. For one past-due notice or reminder to many customers, Bulk Send fills in each name, balance and due date from a spreadsheet, up to 100 per batch.

Mail-merge one notice to your customer list

Documents are encrypted in transit and at rest. Your documents are processed automatically. We never read or review the content of your mail. Our print partner prints and mails each letter.

How we handle your documents

Not yet. Return or remittance envelopes and perforated stubs aren't available. Print your remit-to address and a pay-online link on the invoice; a remittance slip in your PDF prints with the invoice, and customers who pay by check use their own envelope. Monthly auto-send and Certified Mail aren't available yet; you start each send. Volume pricing is not currently available. Letters go to U.S. addresses only.

Four ways to mail invoices, compared

Your invoice prints as you made it, with your logo and remit-to details, and your business name and address are the return address in the top window. It goes out in a #10 double-window envelope with a security tint. Printed or branded envelopes aren't available yet, so your business name in that window is what your customer sees first.

Different invoice PDFs go in your Cart, each with its customer, and you pay for up to 10 together, so 200 invoices take 20 checkouts. For one notice to many customers, Bulk Send fills in each name, balance and due date from your spreadsheet, up to 100 customers per batch, so 200 customers take 2 batches. A combined export isn't split into separate letters yet, so save one PDF per invoice. Volume pricing is not currently available.

Put the PO number on your invoice before you export the PDF; it prints as you made it. A typed address doesn't have a separate company line yet, so type "Accounts Payable" and the company name in the Name field, up to 40 characters. Importing customers from a spreadsheet? A company column comes through with each address. Check the address page in your preview before you pay.

Save each client's business address in your address book, then choose it as the return address on that client's letters; your default return address fills in until you pick another. Every letter in your Cart keeps its own return address, and each Bulk Send batch uses one return address. Inviting clients or colleagues to your account isn't available yet.
