Frequently asked questions

Is Invoice Simple free?

Not on an ongoing basis. Invoice Simple offers a 14-day free trial, after which you choose Essentials (US$6.99 a month for up to 3 invoices), Plus (US$14.99 for up to 10) or Premium (US$21.99 for unlimited invoices). Its website also has a free one-off invoice generator. InvoiceSonic lets you create your first invoice with no account and includes 3 saved invoices a month on a free account.

What is the best free alternative to Invoice Simple?

For a free ongoing plan, InvoiceSonic (3 saved invoices a month plus a no-signup generator), Zoho Invoice (free for small businesses) and Wave (free invoicing, fees on card payments) are the usual picks. Which is best depends on whether you need recurring invoices, reminders or accounting features.

How much does Invoice Simple cost compared with InvoiceSonic?

Invoice Simple is US$6.99, US$14.99 or US$21.99 a month depending on how many invoices you send, with two months free if you pay annually. InvoiceSonic Pro is A$19 a month or A$168 a year for unlimited invoices, recurring billing, automatic reminders and quotes, after a 7-day trial. Prices checked 20 October 2026.

Does Invoice Simple do recurring invoices?

Invoice Simple does not schedule recurring invoices; the usual workaround is to duplicate a previous invoice each period. InvoiceSonic Pro creates recurring invoices weekly, fortnightly, monthly, quarterly or yearly and queues each one for you to send.

Can I move my clients and invoices from Invoice Simple to InvoiceSonic?

Yes. Download your invoice PDFs and client list from Invoice Simple before your subscription ends, add your clients to InvoiceSonic (they are saved after the first invoice), and continue your invoice numbering from where you left off so your records stay in sequence.

Does InvoiceSonic have a mobile app like Invoice Simple?

InvoiceSonic has a native iPhone and iPad app plus a browser app that works on any phone or desktop, with the same account across both. Invoice Simple also offers an Android app, so Android-only users should weigh that.
