Key Features

Everything you need to collect payments from tenants — zero-integration alias for day one, full API when you need it.

@casapay.me aliases

Unique email alias per tenant. Forward invoices from any PMS and we handle the rest — no integration, no migration.

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. Works with any PMS — no integration required.

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.
