Inkvoice vs PayPal Invoicing

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.

PayPal Invoicing lets freelancers, service professionals, consultants, and small businesses bill clients directly. Users can customize invoices with a company name, brand colors, logo, taxes, discounts, shipping details, and notes, then send them by email, SMS, messaging apps, social media, or QR code. A dashboard tracks whether invoices have been sent, opened, or paid. Templates support recurring billing; automatic reminders and QuickBooks and Xero sync can reduce manual work. Invoices can be created and managed on the web, iOS, and Android, including through the PayPal app. A PayPal account is required to create and send invoices, but clients do not need one to pay. Creating and sending invoices costs nothing; transaction charges apply when customers pay. The listed PayPal and Venmo rate is 3.49% + $0.49 per transaction, and Pay Later is 4.99% + $0.49 per transaction. Fixed fees vary by currency received, and international transactions may add a percentage-based fee. Availability is listed in over 200 markets and 24 currencies.
