About this app

Cortina Invoice is a GST-ready billing app built for Indian freelancers,
shopkeepers and small businesses — create tax invoices, track clients and
stock, and manage your books, all from your phone.

WHAT YOU CAN DO
• Create GST tax invoices with CGST/SGST/IGST split, HSN/SAC codes and
auto-generated PDFs
• Track clients and suppliers, each with GSTIN, PAN, address and running
balance
• Manage items and stock — sale price, purchase price, quantity on hand
• Record purchases, ledger entries and payments (in/out)
• Reports: outstanding, paid, overdue, at a glance
• Built-in Calc tools:
– Simple calculator
– GST Lab — exclusive/inclusive GST, CGST+SGST or IGST, any rate
– Tax/TDS calculator — net receivable after TDS withholding across
common sections (194J and more)
• Custom Terms & Conditions — set your own default terms, override per
invoice
• Try it instantly — skip business setup and explore with demo data before
entering your real GSTIN

PLANS
• Free — 5 invoices, 10 clients, core features
• Free trial — full access for a limited time
• Silver / Gold — higher limits, watermark-free invoice PDFs (Gold)

YOUR DATA
This version of Cortina Invoice stores your business data locally on your
device only — invoices, clients, items, ledger. Nothing is sent to a
server. See the in-app Privacy Policy and Data Safety pages for full
detail, including what that means for backups (there is no cloud recovery
yet — export/back up records you need to retain).

Built by Lexcore Enterprises Private Limited.
