Invoicing that runs on WhatsApp
Your clients already live on WhatsApp; your email invoices get buried. With Regulus you create and send invoices by text or voice note — "invoice John $500 for the logo work" — and clients pay from the chat through one link.
Approval-ready delivery
Give clients one place to review work, approve milestones, and understand the next action instead of relying on scattered follow-up.
Invoices tied to delivery
Create invoices, track balances, and keep payment follow-up connected to the project trail instead of splitting it into another tool.
Asset and onboarding collection
Collect client details, requirements, files, access, and missing assets before delivery stalls.
Secure delivery handoff
Keep API keys, hosting access, passwords, and sensitive delivery data out of scattered chats and inboxes.
Best for
- Freelancers whose clients answer WhatsApp faster than email
- Service businesses that quote and confirm work in chat
- Agencies sending reminders clients actually read
- Operators who want to invoice from their phone, by voice note
Not the best fit for
- Businesses whose clients require formal procurement portals
- Teams that never communicate with clients on WhatsApp
- Enterprises that need a dedicated accounting suite first
