OneBookPlus vs Fergus
Job management, plus the accounting
Fergus is solid Australian-built job management, but the bill grows with your crew and syncs your books out to Xero or MYOB. OneBookPlus gives tradies the same quoting, scheduling and invoicing plus native accounting, bookings, CRM, marketing and AI in one flat-priced app.
Key takeaways
5- Fergus pricing (AUD): Essentials from A$53/month, Professional from A$77/month, timesheet users from A$26/month, contractors A$4/user/day, Enterprise 10+ custom. 14-day trial, no free plan (source: fergus.com/au/pricing, checked 2026-08-02).
- Fergus has no native accounting, it syncs invoices and contacts to Xero, MYOB or QuickBooks, so most tradies run Fergus plus a separate ledger subscription and reconcile across two systems.

- OneBookPlus replaces that stack with one flat-priced platform from $0/month (Free), $29 (Starter), $49 (Plus) or $69 (Growth), quoting + jobs + invoicing + accounting + BAS + bookings + CRM + marketing + AI bundled, team included, with no per-user fee.
- Both are Australian-built with strong quoting, scheduling, GST invoicing and native iOS + Android apps. Fergus genuinely leads on dispatch depth and 100+ automated supplier-invoice feeds (Reece, Tradelink, CEF, City Plumbing).
- Fergus wins on: dispatch depth, mature supplier feeds, and a large trades install base. OneBookPlus wins on: flat pricing that doesn't scale per head, bundled AU accounting/BAS/STP (no second subscription), and customer-facing bookings + marketing + AI that Fergus doesn't offer.

Where Fergus wins
Credit where it’s due
Fergus is a mature, Australian-built job-management platform with a large trades install base, and that focus shows. Its visual scheduling and dispatch board is purpose-built for keeping multiple crews and jobs straight, and its 100+ supplier integrations (Reece, Tradelink, CEF, City Plumbing and more) pull merchant invoices straight onto the job card, genuinely useful automation for materials-heavy trades that OneBookPlus doesn’t replicate today. Fergus also ships native iOS and Android apps and syncs cleanly to Xero, MYOB or QuickBooks, so if your books already live in one of those and supplier-feed automation is core to your costing, Fergus is a strong, well-supported choice.
Where OneBookPlus wins
Three differences that compound
Accounting is bundled, not synced out to Xero. Fergus has no native accounting. Per its own product pages it syncs invoices and contacts to Xero, MYOB or QuickBooks, where your P&L, balance sheet and BAS live. OneBookPlus ships full accounting, GST tracking, quarterly BAS-ready figures (G1, 1A, 1B), STP Phase 2 payroll and SuperStream inside the same subscription: one system, one source of truth, no reconciliation tax at quarter-end.
Flat pricing that doesn’t scale per head. Fergus’s pricing page quotes from A$53/month on Essentials and A$77/month on Professional, and those are starting figures that move with your user count, plus A$26/month per timesheet user and A$4/user/day for contractors, on top of your Xero or MYOB bill. OneBookPlus is a flat plan with the team included, and a $0 Free tier rather than a 14-day trial that ends.
Customer-facing bookings, marketing and AI. Fergus is built around the back-office job, not winning the next one. OneBookPlus adds a white-label online booking page, automated Google review requests, email campaigns, and an AI Companion that chases no-shows, follows up quotes, runs winback and writes your end-of-day summary, capabilities Fergus does not publicly document.

Why Australian tradies move from Fergus to OneBookPlus
One bill instead of two
Fergus plus Xero or MYOB means two subscriptions, two systems and a sync to reconcile. OneBookPlus bundles accounting and BAS, so it's one platform and one source of truth.
Pricing that doesn't punish growth
Fergus quotes from A$53 to A$77 a month and adds per-user charges for timesheet and contractor logins, so hiring costs you more software. OneBookPlus is flat, with the whole team included.
Win work, not just track it
Fergus manages jobs you already have. OneBookPlus adds an online booking page, automated review requests and email marketing to bring in the next job.
AI that does the admin
The AI Companion chases overdue invoices, follows up quotes, runs winback and writes your end-of-day summary, automation Fergus doesn't offer.
Who should switch from Fergus to OneBookPlus
Solo tradies and small crews tired of paying twice.
If you're paying for Fergus and again for Xero or MYOB just to invoice and lodge BAS, OneBookPlus folds both into one flat plan from $0 to $69/month, with the team included rather than priced per head.
Businesses that want to win more work.
Fergus is built around managing the jobs you already have. If you want a customer booking page, automated Google review collection and email marketing to stay top-of-mind with past clients, OneBookPlus includes them.
Tradies who hate reconciling job software with their ledger.
If quarter-end means checking that Fergus invoices match Xero, or your bookkeeper charges to fix sync gaps, a single system removes the problem: the invoice and the accounts are the same record.
When Fergus might still be the better fit:
If automated supplier-invoice feeds from merchants like Reece, Tradelink and CEF are core to how you cost jobs, or you run multiple crews where a dedicated dispatch board is the most-used screen of your day, Fergus's depth in those areas is genuine. You're already invested in a connected Xero or MYOB workflow, and the switch isn't urgent.
How to switch from Fergus to OneBookPlus
Export your customers and active jobs
In Fergus, export your customer list as a CSV and note your live jobs. Import the contacts straight into OneBookPlus: names, emails, phone numbers and addresses all map across. Keep Fergus active as a read-only archive for history.
Set up your services, pricing, ABN and branding
Configure your service list and rates, upload your logo, and set your ABN, GST preferences and payment terms. About 15 minutes, and because accounting is built in, you don't need to wire up a separate Xero or MYOB connection.
Run new jobs in OneBookPlus, wind down Fergus
Start all new quotes and jobs in OneBookPlus while finishing existing ones in Fergus. Most tradies run both for a month, confirm BAS figures reconcile, then cancel Fergus, and the separate Xero/MYOB subscription if it was only there for Fergus.
OneBookPlus vs Fergus: your questions answered
OneBookPlus or Fergus: which suits a trade business better?
It depends on what you need. Fergus is a mature, Australian-built job-management tool with excellent scheduling, 100+ supplier feeds, and tight Xero/MYOB sync, if dispatch and supplier-invoice automation are the centre of your day and you already run Xero, Fergus is a genuinely strong fit. OneBookPlus is the better fit if you want the same quoting, scheduling and invoicing PLUS native accounting, BAS, online bookings, CRM, marketing and AI in one flat-priced platform, without running a second accounting subscription.
How much does Fergus cost compared to OneBookPlus?
Fergus publishes Essentials from A$53/month and Professional from A$77/month, with timesheet users from A$26/month and contractors at A$4/user/day (source: fergus.com/au/pricing, checked 2026-08-02). Those are "from" prices: Fergus sells set feature tiers with flexible user options, so the figure you are quoted rises with the size of your crew. There is no free plan, just a 14-day trial. Most tradies also pay for Xero or MYOB on top because Fergus has no native accounting. OneBookPlus is a flat plan, $0 Free, $29 Starter, $49 Plus, or $69 Growth per month, with the whole team and the accounting included.
Does Fergus include accounting and BAS?
No. Fergus handles GST on invoices, deposits and progress claims, but it has no native accounting engine, it syncs invoices and contacts to Xero, MYOB or QuickBooks, where your P&L, balance sheet and BAS live (source: fergus.com/au). OneBookPlus includes a full Australian accounting engine: P&L, balance sheet, GST tracking, quarterly BAS-ready figures (G1, 1A, 1B), STP Phase 2 payroll and SuperStream, all in the same subscription, so there's no second bill and no sync to reconcile.
Can OneBookPlus replace Fergus?
For most solo tradies and small teams, yes. OneBookPlus covers the core Fergus workflow, quoting, job scheduling, time and materials, GST invoicing, on-site card payments and a native mobile app, and adds accounting, BAS, online bookings, CRM, marketing and AI. The main thing Fergus does that OneBookPlus does not is automated supplier-invoice feeds from merchants like Reece, Tradelink and CEF; if that automation is core to your costing, weigh it before switching.
Is Fergus or OneBookPlus better value for a small team?
Fergus quotes plan prices from A$53/month (Essentials) and A$77/month (Professional), and those are starting figures that move with your user count, plus A$26/month per timesheet user and A$4/user/day for contractors (fergus.com/au/pricing). Add a Xero or MYOB subscription for the books, because Fergus has none. OneBookPlus plans are flat and include your team and your accounting, so the bill does not move when you put another apprentice on. Ask Fergus for a quote at your actual headcount and compare it against $29, $49 or $69 a month.
Is OneBookPlus Australian-built like Fergus?
Yes. Both are Australian businesses, Fergus is based in Woolloomooloo, NSW (source: fergus.com/au), and OneBookPlus is Australian-built and hosted on AWS in Sydney (ap-southeast-2), with GST, ABN validation and BAS reporting native to the platform rather than handled through a connected accounting product.
How does OneBookPlus compare to other Fergus alternatives like ServiceM8 or Tradify?
ServiceM8, Tradify, AroFlo and simPRO are the usual head-to-head Fergus alternatives, and like Fergus they are job-management-first: strong on quoting, scheduling and dispatch, with your accounting handled in a connected Xero, MYOB or QuickBooks subscription. OneBookPlus differs by bundling native AU accounting, BAS-ready figures, online bookings, CRM, marketing and AI alongside the job-management core, in one flat-priced app instead of a job tool plus a separate ledger. If dispatch depth is your one criterion, compare those dedicated tools directly; if one bill and one system is the goal, that is the OneBookPlus case.
Can I keep Xero for my accountant and still use OneBookPlus?
Yes. OneBookPlus exports contacts and transactions as CSV and in a Xero-compatible format, so your accountant can keep working the way they do now while you run quoting, jobs and invoicing in OneBookPlus. Many switchers run both for a quarter, confirm the BAS figures reconcile, and then decide whether to keep the separate ledger at all, since P&L, balance sheet and BAS-ready figures are built into OneBookPlus. Talk to your accountant about timing before you cancel anything.
Does OneBookPlus have an Android app like Fergus?
Not a native one today. Fergus ships native iOS and Android apps (fergus.com/au). OneBookPlus has a native iOS app; on Android you use the web app in your browser, which covers quoting, jobs, invoicing and the CRM but is not a native install. If your crew is mostly on Android and a native app is a hard requirement, that is a genuine point in Fergus's favour.
