Inkvoice vs SumUp Invoices

Inkvoice is open-source invoicing software for freelancers, small businesses, and small teams. It creates invoices and quotes, which can be turned into invoices, shared through links, or exported as PDFs. Recurring invoices can be generated automatically on monthly, quarterly, or annual schedules. Customers can pay through Stripe or PayPal checkout; users can also 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 opt-in e-invoicing module supports EN 16931 formats, including ZUGFeRD 2.2, XRechnung, and PEPPOL BIS. Inkvoice runs on the web, Linux, through an API, or as a self-hosted deployment. The self-hosted build stores application data in a SQLite file and can run in a Docker container. Cloud Free is free, with one user and five customers; Cloud Starter is $4.99 a month, and Cloud Pro is $14.99 a month. Both paid cloud plans offer yearly billing with two months free.
