BizziKit

Twenty-eight free business tools — invoicing, accounting, payroll, CRM, quotes, mileage, receipt scanning — that run entirely in the browser, install as an app, and keep every figure on the user's own device.

The challenge

A sole trader or a small business needs perhaps a dozen small pieces of software: something to raise an invoice, something to work out a payroll figure, something to track mileage for the tax return. Each of those exists as a SaaS product with a monthly fee and a sign-up form, and none of them is worth a subscription on its own.

The other half of the problem is quieter. Every one of those tools asks you to upload your financial data to somebody else's server to do arithmetic that your own machine could do in a millisecond.

Our solution

A single site with the whole set, free, no account, and — the part that decides the architecture — nothing leaves the browser. Invoices, ledgers, payroll figures and scanned receipts are computed and stored on the user's own device. The site states it in four words on the front page: your business, your data, your way.

That is the same stance we take across our studio and compliance products, and it is easier to hold to here than anywhere: none of these calculations need a server, so there is no good reason to send the data to one.

Four promises sit at the top of every page and the build has to keep all of them at once: free with no fees ever, no signup, private with data staying in the browser, and working offline as an installed app.

What we built

• Finance and accounting: invoice builder with templates, multiple currencies and PDF/HTML export; a general-ledger accounting tool producing P&L, balance sheet, trial balance and journal entries; a profit/loss builder with budget-vs-actual and forecasting.
• Payroll and rates: a payroll calculator covering US, AU, UK, CA and NZ tax brackets with payslip PDF export, plus a freelance rate calculator that works back from tax and overhead to an effective hourly rate.
• Everyday admin: quote and estimate builder that converts a quote to an invoice in one click, mileage tracker and logbook with ATO and IRS rates, subscription tracker with renewal reminders, and business calculators for ROI, loans, break-even, VAT/GST and currency.
• A receipt and expense scanner that reads a receipt with OCR, extracts total, vendor and date, and passes it through to the accounting tool.
• A dashboard pulling it together: calendar, upcoming items across tasks, CRM, invoices and payroll, a Pomodoro task timer with billable tracking and a weekly time chart, goals, quick notes, CRM follow-ups, daily habits, storage usage and scheduled reports.
• News alongside the tools, including world and market coverage, so the site is somewhere to return to rather than only somewhere to complete a task.

Technical decisions

Local-first, and stated plainly. The site tells users their data stays in the browser, which is a promise you can only make if you built it that way from the start. It also removes an entire category of obligation — there is no breach surface in data you never collected.

OCR in the browser. Receipt scanning is the one feature with an obvious excuse to call a server. Doing it client-side keeps the promise intact for the most sensitive input on the site.

Progressive web app. Installable and offline-capable, so the toolkit is available on a job site or a plane, and updates without an app store.

Multi-jurisdiction from the start. Payroll across five countries and mileage on both ATO and IRS rates, because a freelancer's tools are useless if they assume the wrong country.

What shipped

Twenty-eight tools, free, no sign-up, installable, offline-capable, with the user's financial data staying on their own device.

For us it doubles as a reference build: when a client asks whether a browser can carry real business software without a backend, this is the answer we point at.

Tech stack

HTML5 and client-side JavaScript, browser storage for all user data, in-browser OCR, client-side PDF generation, service worker for offline use, web app manifest for install.
