# How does it work? receivabl.es is an add-on to your existing accounting or invoicing software. Its deep integration means there is no change to your current invoicing workflow. We add a button or link to your invoices which takes your customers to a secure payment form. We handle bank account verification, ACH debit authorization, and the transfer of funds from their bank account to yours. We also remember your customer's bank details which makes paying recurring invoices fast and easy. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
