Invoice Simple review
Affordable core invoicing for contractors who work across web and mobile.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Invoice Simple is invoicing software for freelancers, contractors, independent professionals, and small service businesses. It supports branded invoices, estimates, receipts, and payment requests from the web, iOS, and Android. Contractors can convert estimates into invoices, accept online and in-person payments, track invoice status, send reminders, and schedule recurring invoices. The product focuses on invoicing and payments rather than full accounting or enterprise billing, making it a fit for independent operators and small service businesses that need core billing tools across devices.
Its feature set covers several day-to-day contractor workflows. Users can autofill client and item information, customize templates with logos, photos, and signatures, track expenses and receipts, and generate invoices in multiple currencies. Real-time read receipts show whether an invoice has been viewed, while automatic payment reminders and recurring invoices reduce routine follow-up. The published plan structure adds capabilities progressively: Plus adds photos, a business owner signature, summary reports, and due date reminders; Premium adds client signatures, premium templates, deposits, and restoration of previous invoices.
Platform coverage is a practical strength, with web, iOS, and Android apps. Payment connections include Stripe and PayPal, but the integration set is narrow for businesses that need a broader software ecosystem. The product also has no client portal and is designed for one team user, which limits its fit for growing teams with shared workflows. A 14-day Premium trial is available in the mobile app without a credit card, while the web app offers limited free invoice creation before a paid plan is required. Choose Invoice Simple for mobile-friendly invoicing, payments, reminders, and recurring billing; consider another option if you need full accounting, a client portal, or wider integrations.
