Free Invoice Generator — Create and Send Professional Invoices
By HatchSolo · Last updated: August 2026
Creating and chasing invoices is one of the most time-consuming parts of running a solo business. You finish the work, then spend time formatting a document, emailing it, waiting, chasing, chasing again. HatchSolo's invoice generator creates professional invoices through WhatsApp — you give Maya the details (client name, work done, amount, due date) and she generates and sends the invoice immediately. She also tracks whether it's been paid and automatically sends reminders at 7 days, a follow-up at 30 days, and flags anything overdue. The invoice is stored, the chasing is automated, and you never have to think about it again.

- Payment tracking: Maya knows which invoices are paid and which aren't
- Automated reminders: 7-day reminder, 30-day follow-up, overdue escalation

How it works
Give Maya the details
Client name, what you did, the amount, and when it's due. One message.
Invoice sent automatically
Maya generates and sends a professional invoice to your client. You get a copy in WhatsApp.
Chasing handled for you
Maya tracks the payment and sends reminders on your behalf. You only hear about it if it becomes a problem.
Frequently asked questions
Q: What should I include on an invoice?
A: Business name and address, client name and address, invoice number, date, description of services, amount, VAT (if registered), payment due date, and bank details or payment link.
Q: How do I chase a late invoice without damaging the relationship?
A: Be factual, not emotional. A simple "I wanted to check whether payment for invoice #123 (due [date]) has been processed" works well. HatchSolo's reminders are written in this tone.
Q: Do I need to be VAT registered?
A: Not unless your annual turnover exceeds £90,000 (UK threshold as of 2026). Below that, you do not charge VAT. HatchSolo knows your VAT status and generates correct invoices.
Q: Can I customise my invoice template?
A: Yes. Tell Maya your preferences — logo, colours, payment terms, late payment clause — and she applies them to every invoice.
Q: What if a client disputes an invoice?
A: HatchSolo keeps a record of every invoice sent. You have a clear paper trail showing what was agreed, when the invoice was sent, and what reminders went out.
Never chase an invoice manually again.
Give Maya the details. She generates the invoice, sends it, and chases it for you. You just get paid. From £49/month.
