I use Railway to host multiple client websites and web apps, each running as a separate service within one account. My clients pay me for hosting/maintenance on a monthly basis, but since all services are combined on a single invoice, I have no way to see the actual cost of each individual project.

It would be extremely helpful if Railway offered a way to generate separate invoices per service (or per project), so I could see exactly what each client's site costs to run. This would make it much easier to price hosting correctly and bill clients accurately for their actual usage.

Even a simple cost breakdown by service on the existing invoice, in addition to a way to export/generate individual invoices, would solve this for agencies and freelancers managing multiple client deployments.
