Can I invoice for EICR testing through WhatsApp?

Yes. Message WOPA with the customer name, amount, and job description. WOPA drafts the invoice, you approve it, and the PDF is emailed to your customer.

Does WOPA handle staged invoicing for large electrical jobs?

You can send multiple invoices to the same customer for different stages of a job. Each invoice is tracked separately with its own reminder schedule.

Can I chase multiple customers at once after a busy week?

Yes. Ask WOPA 'who hasn't paid?' and you'll see all outstanding invoices. You can chase all overdue customers with a single message.
