Maria runs a growing consulting practice. She’d been using basic invoicing methods for months – sometimes Word documents, sometimes simple templates – but her business growth demanded something more professional. She needed real invoicing software.
After research, Maria narrowed her choices to two popular options: InvoiceZap and Invoice Simple. Both had good reviews, reasonable pricing, and seemed designed for small businesses like hers. But which would actually work better for her specific needs?
Maria spent two weeks testing both apps extensively. She created test invoices, explored the mobile capabilities, tested payment processing, and evaluated how each handled her consulting workflow. The results surprised her.
While both apps could handle basic invoicing, the differences in mobile optimization, feature depth, and business growth support were significant enough to clearly influence her decision.
Here’s Maria’s complete comparison – updated for 2025 – to help you choose between InvoiceZap and Invoice Simple based on real-world usage and business needs.
