Key Features

Everything you need to collect payments from tenants without writing a single line of code.

@casapay.me aliases

Unique email alias per tenant. Forward invoices and we handle the rest.

PDF invoice parsing

AI extracts amounts, due dates, and line items from any PDF invoice.

Auto payment pages

Hosted payment page generated automatically for each parsed invoice.

Tax rate management

Configure VAT/GST rules per property. Automatically applied to every invoice.

How it Works

Three steps. No code. No onboarding calls.

1

We create an alias

We generate a unique @casapay.me email address for each of your tenants.

2

You forward invoices

Send invoices to the alias instead of the tenant email. PDF, HTML, or image attachments all work.

3

Tenant gets a pay link

CasaPay parses the invoice and creates a branded payment page the tenant can pay instantly.
