Core Capabilities

Architected for independent operators who value speed and clarity.

Traditional accounting software forces solo founders into ledger double-entries, slow portal logins, and hidden processing cuts. We stripped away the tax filing bloat and kept only what gets you paid.

Frequently Answered

Frequently Asked Questions

Are there any hidden transaction fees or surcharges? expand_more
None. We never charge transaction commissions, invoice generation fees, or payment surcharges. You connect your own payment links (such as Stripe or direct bank transfers) directly to your clients.
Can I really manage multiple businesses under one account? expand_more
Yes! Our Pro plan includes up to 3 distinct business profiles, and the Studio plan allows unlimited profiles. Each profile maintains its own business name, logo, contact info, client directory, and invoice numbering sequence.
What happens during the Early Access / Preview period? expand_more
All features across all plans—including Pro and Studio capabilities like automated retainers and multi-business profiles—are completely unlocked and free to use while self-service billing is in preview.
How do my clients view and download their invoices? expand_more
Each invoice has a private, unguessable share link. When you send it to your client, they can view a clean, print-optimized invoice and download a PDF directly in their browser without signing up for an account.
Can I export my data if I decide to switch tools? expand_more
Yes, always. We believe you should own your financial data. You can download a complete JSON backup containing all your clients, profiles, invoices, and payment records at any time with a single click, and restore it whenever you wish.
How does the annual billing discount work? expand_more
When you choose annual billing, you receive an ~18% discount compared to monthly rates. Pro is $89 billed annually (equivalent to ~$7.42/month) and Studio is $189 billed annually (equivalent to ~$15.75/month).
