Where the difference between an enterprise field-service point tool and an all-in-one, AU-tax-native business platform shows up. simPRO is genuinely deeper on project ops, asset maintenance, and warehouse inventory; OneBookPlus bundles bookings, marketing, and accounting that simPRO leaves to other subscriptions.

Where simPRO wins
simPRO has spent many years building for one customer: the enterprise trade contractor. That focus is real depth, not marketing. Its project-management module handles multi-stage commercial jobs with retentions, complex variation orders, and granular cost-to-complete tracking that a large commercial fit-out actually needs. Its asset-maintenance module runs recurring service contracts, captures asset test readings via barcode/QR scanning in the field, and reports against SLAs, the kind of workflow a mechanical-services or fire contractor lives in. Add mature multi-warehouse inventory with supplier catalogues, and you have a tool that genuinely earns its place at the top of the market. If you run a large field-service operation on long-running enterprise contracts, that specialism is worth paying for, and the switch is not urgent.
Where OneBookPlus wins
Accounting is bundled, not a separate Xero bill. OneBookPlus ships full P&L, balance sheet, automatic bank-feed reconciliation, quarterly BAS reports, STP Phase 2 payroll, and SuperStream inside the same subscription. simPRO’s features page routes accounting through a Xero or MYOB integration, so an enterprise simPRO seat plus Xero is two subscriptions, a sync point that breaks, and a reconciliation tax every quarter-end.
Bookings, marketing & reviews that win the next job. simPRO is built to deliver work you already have, not to generate it. There is no customer-facing online booking page, no email-marketing campaigns, and no automated Google review requests documented on its features page. OneBookPlus bundles a shareable booking widget, email campaigns, and post-job review harvesting: the front-of-funnel a growing trade business needs but an enterprise point tool ignores.
Published price, self-serve setup, no setup fee. simPRO’s pricing page publishes no dollar figure. You contact sales for a custom quote and pay an upfront setup fee for onboarding, training, and data migration before you send a single invoice. OneBookPlus shows $0 / $29 / $49 / $69 on the website, charges no setup fee, and gets you to your first invoice in under an hour with no consultant in the loop.
simPRO's pricing page bundles an upfront setup fee for consultant-led onboarding, training, and data migration before you go live. OneBookPlus is self-serve, connect your bank, import contacts, and you're invoicing within fifteen minutes, with no setup fee.
simPRO uses custom, contact-sales pricing built for 20+ tech operations, with no dollar figure published. OneBookPlus starts free and tops out at $69/month, a price you can see before you sign up, built for sole traders and growing teams up to 20 staff.
simPRO needs Xero or MYOB running alongside it for BAS, P&L, and GST reporting. OneBookPlus includes accounting natively, no second subscription, no syncing issues, no quarterly reconciliation panic.
simPRO focuses on field-service operations. OneBookPlus adds online booking pages, email marketing campaigns, and Google review requests so you can win more jobs, not just deliver them.
A simPRO deployment means a custom enterprise quote plus a separate Xero or MYOB subscription for accounting plus an upfront setup fee. OneBookPlus delivers the same core workflows for a published $0 to $69 a month, accounting bundled, no setup fee, no second subscription.
The two are aimed at different ends of the market. simPRO is built for contractors with 20+ techs, complex multi-stage building services projects, and enterprise field-service operations, and its custom-quote, contact-sales pricing is set accordingly. Its project costing, asset-maintenance contracts, and multi-warehouse inventory go deeper than anything OneBookPlus offers. For sole traders and growing teams under 20 staff, OneBookPlus delivers the core capabilities (quoting, scheduling, invoicing, CRM, timesheets) with no implementation consultants, no enterprise quote, and accounting built in. If you're under 20 staff and don't need simPRO's heavy project ops, OneBookPlus's published $0, $29, $49, or $69 a month is the more predictable path.
Yes. simPRO requires Xero or MYOB to handle accounting, BAS, and P&L reporting on top of its own subscription and implementation fees. OneBookPlus includes accounting, expense tracking, BAS-ready reports, GST compliance, and P&L statements natively, alongside quoting, scheduling, invoicing, and CRM. One platform, one subscription, no double data entry between systems.
simPRO doesn't publish a price. Its pricing page (simprogroup.com/pricing, checked August 2026) asks you to contact sales for a custom quote tailored to the add-ons you need, plus an upfront setup fee covering onboarding, training, and data migration. Because no dollar figure is published, the only way to learn the real cost is a sales call, and that is worth knowing before you book one. You'll also need Xero or MYOB on top for accounting, since simPRO routes BAS, P&L, and GST through an accounting integration, which is a second subscription on top of the simPRO quote. OneBookPlus publishes its price: $0, $29, $49, or $69 a month with everything included, so you know exactly what you'll pay before you sign up, with no setup fee and no separate accounting bill.
Yes, for most small-to-mid trade businesses. OneBookPlus supports job stages, progress invoicing, materials and labour tracking, and multi-step workflows that cover the vast majority of building services jobs. simPRO has more granular project operations (deeper retentions, complex variation orders, asset maintenance contracts) tailored for very large contractors managing dozens of long-running enterprise projects. If you're a large building services contractor with 50+ technicians on enterprise contracts, simPRO's depth makes sense. For everyone else, OneBookPlus does the job at a fraction of the cost.
At that size the two are aimed at different problems. simPRO is often more tool than a small crew needs: you pay an enterprise quote, sit through a consultant-led implementation, and use a fraction of what you bought. OneBookPlus delivers quoting, scheduling, invoicing, timesheets, CRM, accounting, BAS, marketing, and online bookings in one app, set up in fifteen minutes, with no consultant fees. Built specifically for Australian tax compliance and Aussie tradie workflows from day one. Above that size the answer flips: simPRO's project costing, asset-maintenance contracts and multi-warehouse inventory go deeper than anything OneBookPlus offers, and that depth is exactly what large contractors are paying for.
A BAS (Business Activity Statement) is the form Australian businesses lodge with the ATO to report GST collected on sales, GST paid on purchases, and the net amount owed or refunded. OneBookPlus generates BAS-ready figures automatically from your invoices and expenses, so you can lodge or hand them to your accountant without exporting to a separate accounting tool. simPRO has no native accounting, so BAS reporting runs through Xero or MYOB on top of your simPRO subscription.
simPRO is a powerful piece of software, there's no question. It dominates the enterprise field-service space for a reason: deep project costing, fleet tracking, asset maintenance contracts, and granular workflow customisation built for contractors running 20, 50, or 100+ technicians on long-running building services contracts. The problem is that small and mid-sized Australian trade businesses end up paying for all of that depth and using only the part that matches their week. OneBookPlus is built for the other end of the market, sole traders, growing teams, and trade businesses up to roughly 20 staff who need the same core capabilities without the enterprise overhead.
Where simPRO thinks in projects, change orders, and retentions, OneBookPlus thinks in cash flow and Aussie tax compliance. Every quote you send, every invoice that gets paid, and every supplier receipt you snap on your phone feeds directly into your financial picture, no exports, no Xero syncs, no consultant rebuilds when your workflow changes. You see what you've earned, what you're owed, and what the ATO needs, updated in real time.
Self-serve setup, not consultant-led implementation: simPRO's pricing page bundles an upfront setup fee for consultant-led onboarding, training, and data migration before you ever send your first invoice, the exact figure quoted to you on a sales call. OneBookPlus is self-serve from day one. Connect your bank feed, import your client list, set your ABN and GST defaults, and you're live within fifteen minutes. No project plan, no consultant rates, no setup fee, no go-live deadline.
Quoting to invoice to bank reconciliation, in one flow: Create a quote on site from your phone, send it for one-click acceptance, and convert it to an invoice when the job's done. Materials, labour, and markup carry through automatically. Payment reminders go out on schedule. When the client pays, the transaction matches against your bank feed without you touching it. simPRO can do most of that, but only after you've also configured Xero or MYOB on the back end and paid for both subscriptions.
GST and BAS built into every transaction: Every line item, every expense, every invoice has GST handled natively, not bolted on via an accounting integration. When BAS time comes, your figures are already calculated. No exporting from simPRO into Xero, no chasing missing receipts across two systems, no consultant call to debug a sync that broke. OneBookPlus generates BAS-ready reports directly, built for Australian tax law from the ground up.
Stay with simPRO if: you run a large enterprise contracting operation with 30+ technicians, manage long-running multi-stage building services projects with retentions and complex variation orders, or rely on simPRO's asset maintenance, fleet tracking, and detailed project costing modules for high-value contracts.
Switching takes about fifteen minutes, no consultant required. Start by connecting your business bank account; OneBookPlus pulls in recent transactions automatically through its bank feed. Next, export your client and job data from simPRO (Reports > Export) and import the CSV into OneBookPlus. Set your default GST treatment, ABN, and payment terms. From there, any new quotes and invoices happen in OneBookPlus, and your bank feed keeps your books current, no second app, no implementation invoice, no per-user enterprise charge.
Published pricing, self-serve setup, and no implementation consultants required.
Free plan available, no card needed.
