What Inkvoice is
Inkvoice is open-source invoicing software for freelancers, small businesses, and small teams. It handles invoices and quotes, allows quotes to be converted into invoices, and provides shareable invoice links and PDF output. Recurring invoices can be set monthly, quarterly, or annually and generated automatically. Customers can pay through Stripe or PayPal checkout, while users can record manual and partial payments. The software tracks billable expenses and provides tax summaries, accounts-receivable aging, profit-and-loss reports, and cash-flow forecasts. An optional e-invoicing module supports EN 16931 formats including ZUGFeRD 2.2, XRechnung, and PEPPOL BIS. Inkvoice is available through cloud plans or as a self-hosted build; the latter stores application state in a SQLite file on the user's server and can run in a Docker container. Cloud Free is free and includes one user, five customers, and unlimited invoices. Cloud Starter is $4.99 a month for up to three users, while Cloud Pro is $14.99 a month for up to ten users. The self-hosted build is free and lists all features with no caps.
