Invoicing for freelancers
Send the invoice. Watch the money come in.
Caishen is the calm workspace for freelance billing: professional invoices, a client book, payment tracking and an income dashboard, all in one place.
$9/month after the trial. Cancel anytime.
Quote it, track it, bill it, and get paid. One workspace.
Invoices that look the part
Line items in hours, days or fixed fees, per-line tax, discounts, deposits and a paid-in-full stamp. Clean PDF in one click.
Get paid right from the email
Every invoice email can carry a Pay now button that opens a secure Whop checkout. Funds go to your own balance and the invoice marks itself paid. Share links work the same way.
Estimates that become invoices
Quote the work, track sent, accepted and declined, then convert an accepted estimate into an invoice in one click.
Recurring billing on autopilot
Turn any invoice into a weekly, monthly, quarterly or yearly schedule. Draft invoices appear when they are due, ready to review and send.
Time tracking that bills itself
Run a timer or log hours, then select entries and create the invoice. Billed time is marked so nothing gets charged twice.
Expenses and real profit
Log spending by category and see profit by month. Caishen keeps a running tax set-aside number so April holds no surprises.
Reports and cash forecast
Income by client and month, an aging report of who owes you, and a forecast based on how each client actually pays.
An assistant that does the work
Say “invoice Acme for 12 hours at $85, net 30” or “log my Figma expense” and it drafts it. It never sends or deletes without you.
Email and chase in one place
Send invoices from Caishen with your own message, then let AI draft firmer reminders for anything overdue. You review every email.

Questions
Where is my data stored?
Your invoices and clients are saved in your own browser on the device you use. Download a backup from Settings to move to another device.
Can I email invoices from Caishen?
Yes. Send any invoice to your client in one click with your own message. Replies go straight to your email, and the invoice is marked as sent.
How do clients pay me?
Turn on online payments in Settings and verify your identity with Whop once. Your invoice emails then carry a Pay now button that opens a secure Whop checkout. The money goes to your own Whop balance, you withdraw it to your bank, and the invoice is marked paid for you. Standard Whop payment fees apply.
Can I cancel anytime?
Yes. The first 7 days are free, then it is $9 per month and you can cancel whenever you want.
What about taxes?
Set a default rate and mark each line as taxable or not. Caishen calculates the tax after any discount.
