WaPay is a business tool that automates invoicing and payment collection through WhatsApp and a web application. Its primary function is to convert a voice note or text message into a VAT-ready invoice, which is then sent to the customer along with a payment link. The tool is designed for small and medium enterprises (SMEs) and sole traders who want to reduce administrative work after completing a job. Payments are processed through Stripe and deposited directly into the user’s own business bank account, with no funds held by WaPay. Key features include voice invoicing, where a recorded voice note or typed message generates a professional invoice. Customers can pay in one tap using bank transfer, card, Apple Pay, or Google Pay. Automated reminders are sent via WhatsApp on a schedule and stop once payment is received. The tool also supports creating quotes that, when accepted, convert into booked jobs. Every invoice includes the correct VAT rate and is logged for audit purposes. A live dashboard displays received, outstanding, overdue, and VAT payable amounts across any screen. A typical workflow begins when a user finishes a job and records a quick voice note or sends a text via WhatsApp. WaPay creates the invoice and sends a payment link to the customer before the user has packed up. The customer pays immediately, and the funds arrive in the user’s bank account without waiting for transfers. The system handles reminders and record keeping, eliminating late-night admin and awkward payment follow-ups. The tool is intended for businesses that want to move from job completion to payment within a single chat conversation. WaPay is built and operated by Jenaige Design Ltd, registered in Dublin (CRO 702966). There is no subscription fee; users pay a small fee only when an invoice is paid. Registration is done online, and there is no app to download. Customers do not need to learn new software. A referral program offers credits: when a user invites another business and both complete five pay-by-bank payments, the inviter receives 100 euros and the invitee receives 50 euros.
