Freelancers and consultants
Turn a completed project, session, or block of hours into a professional invoice without setting up accounting software.
Common examples: Design work, consulting days, development hours, writing, coaching, and retainers.
For people who need to send an invoice—not run an accounting department
CatInvoice fits independent and owner-led businesses that want a clear document, accurate totals, a record they control, and a quick path back to paid work.

Where CatInvoice fits naturally
Choose a view based on who you are or the billing situation in front of you.
Studios and owner-led agencies
Create branded invoices for different clients, reuse common services, and keep a lightweight local record of what was sent.
Common examples: Creative studios, marketing teams, production shops, and boutique agencies.
Contractors and field services
List labor and materials, add tax or shipping, and print or download the invoice from the browser after the work is done.
Common examples: Repairs, installation, maintenance, photography, events, and home services.
Billing the same client again
Duplicate the last invoice or select saved client and service details, then update the date, quantity, rate, and scope.
Common examples: Monthly retainers, recurring sessions, ongoing maintenance, and repeat orders.
Invoicing in another currency
Choose the billing currency and keep its symbol and decimal format consistent across line items, totals, saved records, and PDF output.
Common examples: Remote services, overseas clients, regional contractors, and cross-border consulting.
Showing what has already been paid
Record a deposit or partial payment so the invoice clearly separates the total from the remaining balance due.
Common examples: Project deposits, milestone payments, event bookings, and staged delivery.
Making an invoice without signing up
Open the editor and work immediately. Drafts, reusable details, and saved invoices remain in the current browser rather than an account.
Common examples: Occasional invoices, private devices, temporary businesses, and people avoiding another subscription.
Keeping your own backup
Export a JSON backup for restoration and a CSV copy for spreadsheet review instead of depending on automatic cloud sync.
Common examples: Device changes, personal archives, year-end review, and offline record keeping.

Is CatInvoice enough for your workflow?
A smaller tool is useful when its boundaries match the job.
| CatInvoice should fit | Consider a larger system |
|---|---|
You are one person or one billing owner | Several people need shared access and permissions |
You send invoices manually when work is completed | Invoices must recur and send automatically |
A PDF, printout, or email attachment is the deliverable | Customers must pay inside a hosted billing portal |
Local storage plus your own backups suits your workflow | Records must sync automatically across devices |
You need invoicing, not full financial operations | You need bookkeeping, payroll, expenses, or reconciliation |
Have billable work in front of you?
The fastest way to know if CatInvoice fits is to make the invoice you already need.
