Invoicing software built for freelancers
Stop rebuilding the same invoice template every month. Waslah Studio creates clean, searchable PDF invoices from your client records, tracked time and billable expenses, and keeps an overview of what is paid, open and overdue.
Everything an invoice needs, without the busywork
Real-text PDF invoices
Invoices export as selectable, searchable PDFs with your logo, company header and footer, in English or German.
Time and expenses on the invoice
Mark time entries and expenses as billable and add them to an invoice directly instead of retyping them.
Proposal to deposit invoice
When a client accepts a proposal, convert it to a deposit invoice in one click.
Recurring invoices
Schedule retainers, hosting and maintenance fees so they invoice themselves on time.
Payments and overdue tracking
Record payments, see what is outstanding on the dashboard and send overdue reminders.
Send it from the app
Email invoices to clients straight from Waslah Studio, or share a secure client portal link.
More than an invoice generator
A one-off invoice generator solves one task. Waslah Studio keeps invoices connected to the client, the project, the hours you logged and the expenses you passed on, so nothing has to be copied between tools. One subscription covers the whole workflow from first lead to final payment.
A note on compliance
Invoice requirements differ by country. Waslah Studio gives you the fields and layout to build a complete invoice, but you stay responsible for the legal content. Check the rules that apply to you with your tax advisor.
