DoubleTime's answer

DoubleTime started from a simple problem: client work often happens in small scattered moments, but invoicing usually happens later.

By the time a freelancer or contractor sits down to invoice, they may be trying to reconstruct what was done, who it was for, whether it was billable, and what rate should apply. That creates billing gaps, delayed invoices, and uncertainty.

DoubleTime was built to keep those pieces connected. Capture the work, apply the right client and rate, review what is ready or blocked, then create the invoice without piecing everything together from memory.

OneBookPlus's answer:

OneBookPlus was founded in 2025 by Bishal Shrestha, a Melbourne-based entrepreneur who'd spent over a decade in digital marketing, web development and small-business consulting.

Like most Australian business owners, Bishal ran his own ventures out of a patchwork of Google Sheets — contacts in one, invoices in another, quotes copied from old emails, bookings in his calendar, receipts in a shoebox. Every BAS season became a lost weekend of reconciling numbers that didn't add up.

Then he spent years consulting for 200+ Australian businesses — plumbers in Melbourne's west, restaurants in the CBD, salons in Sydney, freelancers across the country — and saw the same story everywhere: each was paying $200–400/month for 8–10 disconnected tools (Xero, a CRM, Calendly, Mailchimp, Square…) that didn't talk to each other, all panicking come tax time.

So he sketched OneBookPlus on a napkin at a Melbourne café and built the tool he wished existed: invoicing, CRM, bookings, accounting and marketing in one book, one login, designed for how Australian businesses actually operate — turning BAS into a five-minute job instead of a five-day headache. Proudly Australian: built in Melbourne, designed for GST/ABN/BAS, and priced in AUD.

DoubleTime's answer

Choose DoubleTime if your main problem is not just tracking time, but turning client work into invoices with less guesswork.

DoubleTime is designed for solo billers who want to keep clients, rates, captured work, invoice items, and billing status in one place. It helps show what is ready to invoice, what needs attention, and where billable value may be sitting unbilled.

It is simpler than a full accounting platform, more billing-focused than a generic task manager, and more outcome-focused than a timer alone.

OneBookPlus's answer:

Most competitors solve one slice — accounting (Xero, MYOB), job management (ServiceM8, Tradify) or bookings (Square, Calendly) — leaving you to pay for, integrate and reconcile several tools. OneBookPlus replaces that stack with one platform where your quotes, invoices, payments, bookings, jobs and books already talk to each other — no integrations to maintain, no data silos. It's built specifically for Australian businesses (AUD, GST, BAS, STP, ATO), priced modularly so you only pay for the apps you use, and gives you the same experience on web and mobile.

DoubleTime's answer

DoubleTime connects the work capture and invoicing process instead of treating them as separate jobs.

Many time trackers stop once work has been recorded. DoubleTime goes further by helping users understand what that work is worth, whether it is ready to invoice, what still needs attention, and which invoices are sent, paid, or overdue.

It also supports manual invoice items, so users do not have to track every minute to use the product. They can capture work as they go or add billable items later when needed.

OneBookPlus's answer:

OneBookPlus combines the tools most small businesses normally buy separately — invoicing, quoting, online payments, bookings, job management, contacts and accounting — into one Australian-built platform, with tax and compliance (GST, BAS, Single Touch Payroll, ATO-aligned tax and depreciation) handled natively rather than bolted on. A modular app marketplace (Asset Register, Loyalty, AI Receptionist, Rostering & Payroll and more) lets each business switch on only what it needs, and a native iOS app plus a built-in AI assistant mean you can run the whole business from your phone.

DoubleTime's answer

DoubleTime is built for solo professionals who bill clients for their work, including freelancers, consultants, developers, designers, trade professionals, and other independent service providers.

It is especially useful for people who deal with scattered billable work: calls, fixes, revisions, notes, follow-ups, support tasks, and project work that can be easy to forget by invoice time.

DoubleTime is not aimed at enterprise workforce monitoring. It is for people who need a clearer path from client work to invoice.

OneBookPlus's answer:

Australian small and medium businesses and owner-operators who want to run their whole operation from one place — particularly service and trade businesses (plumbers, electricians, mechanics, cleaners, landscapers), appointment-based businesses (salons, clinics, allied health), and retail, hospitality and professional-services firms. It suits owners and small teams who'd rather not juggle separate apps for quoting, invoicing, payments, bookings, jobs and tax.

DoubleTime's answer

DoubleTime is built as a modern Progressive Web App, allowing it to run in the browser and be installed across desktop and mobile devices.

The PWA approach helps keep the product accessible without forcing users into a platform-specific app store. It also supports the way solo professionals actually work: capturing billable items from different devices, then reviewing clients, rates, invoices, and reports from one place.
