Platform

Marketing site, web app

Bookkeeping that does itself, for freelancers. I designed the marketing site and a web app that sorts your spending, chases invoices and keeps a running tax estimate.

The challenge

Freelancers don't want to do bookkeeping. They want two numbers: what they can safely spend, and what they'll owe in tax. Most tools make them categorise hundreds of transactions to find out.

The approach

Quillo does the sorting and asks only when it isn't sure. I designed every AI suggestion to show its reasoning and be undone in one click, so people trust the numbers it produces.

Plain English, no ledgers

The site

Two numbers on the homepage

The homepage leads with the two numbers freelancers actually want: what's safe to spend, and what to put aside for tax. The rest of the page explains how Quillo works them out.

Onboarding

Connected in two minutes

Onboarding asks a few questions, connects the bank through Open Banking and sorts the last 90 days while you watch. The first thing you see is a finished job, not an empty dashboard.

Dashboard

Safe to spend, at a glance

The dashboard leads with the two numbers people check most. Money in and out, overdue invoices and the next tax date sit below, in order of how often you need them.

Asks only when unsure

AI you can check

Every suggestion shows its working

Quillo asks only when it isn't sure, and every suggestion says why: "You've filed Adobe as software 11 times." Accepting teaches it; changing one fixes every similar transaction.

The details

The small jobs, done for you

Receipts match themselves to transactions, the tax estimate shows exactly how it was worked out, and a monthly email sums up the month in thirty seconds. Every tax figure is labelled an estimate, never advice.

Invoices

Chasing, without the awkward email

Invoices take a minute to make and chase themselves: a friendly reminder at 3 days late and a firmer one at 14, each previewed before it goes.
