Mobile Invoicing
PassionBits
PassionBits is an India-first platform for freelancers and creators. The brief: redesign its desktop invoicing tool for mobile, producing a complete, GST-compliant invoice in the fewest taps across the full create → preview → send journey.
The hardest part to port was the layout. A six-column desktop table can't survive a phone column and a thumb, so it becomes tappable line-item cards, each opening in its own bottom sheet.
The desktop mockup I was handed — the brief was to redesign something like this for a phone.
Everything bends toward the repeat user billing the same few clients. Picking a client auto-fills their details, and only three things are ever required: a client, a line item, a price.
Indian tax is where the real depth sits: GST splits, inclusive-or-added pricing, and TDS deductions that change what you actually receive. All of it folds into one Taxes section, so it never crowds the common case.
The last step is the one that gets you paid, so it leads with WhatsApp, which is how invoices actually move in India, and tracks each one through sent, viewed, and paid. It isn't done until the money lands.
The one-page structure wasn't a given. I prototyped four navigation patterns before the accordion won: the whole invoice on one page, with steps collapsing to summaries as you finish them.
