One place for your customers to pay
A rebuilt portal where customers see every invoice and statement, check in-transit payments, pull PDFs and pay. Nothing waits on a back-and-forth email.



Everything they need to pay, in one page
Open invoices and statements, credit memos, documents, and full payment history sit in one Monk portal. Each invoice shows its in-transit payment status. Customers can pull a PDF or upload an invoice instead of emailing it in.



Fewer emails, faster cash, a clean record
The “can you resend that invoice” thread disappears. Customers find their statements and PDFs, see where a payment stands and pay in one place. Every action lands in Monk, so your record stays clean without manual entry.

If you're in a finance at a fast growing start-up, you should absolutely be using Monk.
Frequently asked questions
What is a customer payment portal?
A customer payment portal is a secure page where your customers see their open invoices, statements, credit memos, payment history, and documents in one place, and pay what they owe without emailing your finance team.
What can a customer do in the portal?
See every open invoice and statement, check what is in transit, pull PDFs and documents, review payment history, and pay: everything that used to be an email to your finance team.
Can customers pay directly from the portal?
Yes. Customers pay invoices directly in the portal. The payment syncs back to your books automatically.
Does the portal reduce inbound "where is my invoice" emails?
Yes. Customers self-serve their own invoices, statements, and documents, so the routine resend requests stop reaching your inbox.
Does the payment portal work with the rest of Monk?
Yes. The portal is wired into collections and cash application: a customer who just paid does not get a reminder, and the payment is matched to open invoices the same day.
