What Inkvoice is

Inkvoice is open-source invoicing software for freelancers, small businesses and small teams, available as a cloud service or self-hosted software. It creates invoices and quotes, converts quotes into invoices, and provides shareable invoice links and PDF output. Recurring invoices can be generated monthly, quarterly or annually. Customers can pay through Stripe or PayPal checkout, and users can record manual or partial payments. The app tracks billable expenses and offers tax summaries, accounts-receivable aging, profit-and-loss reports and cash-flow forecasts. An opt-in e-invoicing module supports EN 16931 formats including ZUGFeRD 2.2, XRechnung and PEPPOL BIS. Cloud Free costs nothing and includes one user, five customers and unlimited invoices. Cloud Starter costs $4.99 a month and supports up to three users; Cloud Pro costs $14.99 a month and supports up to ten. Yearly billing for either paid cloud plan offers two months free. The MIT-licensed self-hosted build costs nothing and lists all features with no caps. It stores app state in a SQLite database on the user's server.
