Express Invoice vs Inkvoice

Express Invoice creates and tracks invoices, quotes, and orders for businesses. It can schedule recurring invoices, automate statements, and send payment reminders. Users can email, print, or fax invoices and quotes, and save or send invoices as PDFs using included templates. Reports cover payments, overdue accounts, salesperson performance, inventory, aging, and sales tax. The software supports multiple tax rates and invoicing for multiple businesses, and it can generate invoices and quotes when the internet is unavailable. It integrates with NCH’s Inventoria to maintain inventory data across a business. Its free version costs nothing, does not expire, and is intended for home users or businesses with one user; it includes most professional-version features. Express Invoice is listed for Android, iOS, macOS, web, and Windows. The mobile apps do not include web access, and remote access through a mobile browser requires the desktop version. NCH recommends regular data backups and offers technical support, video guides, a help manual, and a forum.

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.
