OneBookPlus vs ServiceM8
The complete ServiceM8 alternative

It comes down to how much of the business you want in one app. ServiceM8 is a solid job dispatch tool with online booking forms and a decade-plus of trade-specific work behind it. OneBookPlus adds built-in accounting, BAS reporting, email marketing, and review management in the same subscription. If you only need job dispatch and already have Xero for accounting, ServiceM8 does that job well. If you want one app for everything, OneBookPlus covers more of it.

Yes. OneBookPlus handles quoting, invoicing, job scheduling, customer management, and expense tracking, the core features tradies use ServiceM8 for. Plus you get accounting, BAS reports, online bookings, and marketing tools included.

ServiceM8 prices per job volume rather than per user, from a free plan with a 30-job cap up to Premium Plus, and the full tier-by-tier figures are in the pricing table on this page, taken from servicem8.com/au/pricing. Accounting isn't included at any tier, so most tradies add a Xero or MYOB subscription on top of whichever plan they land on. OneBookPlus starts free with no job cap and tops out at $69/month with accounting, BAS, bookings, and marketing included.

Yes. OneBookPlus includes job scheduling with Google Calendar sync, automated reminders, and a client-facing booking page. While ServiceM8's dispatch features are more field-service focused, OneBookPlus covers the scheduling needs of most tradies, plus adds accounting and marketing.

The ones who switch are usually paying for ServiceM8 and Xero side by side. ServiceM8 focuses on job management and has no native accounting, so OneBookPlus tends to suit tradies who want invoicing, CRM, bookings, accounting, marketing, and job management in one app with GST, ABN, and BAS compliance built in. The ones who should stay are larger field-service operations: if dispatch across 15 or more technicians is the most-clicked screen of your day, ServiceM8's dispatch engine and its mature add-on marketplace are deeper than ours, and its Capterra Australia rating (quoted with its sub-scores further down this page) reflects a decade-plus of trade-specific work we can't claim yet.

Yes, particularly if you do compliance-heavy electrical work. ServiceM8's electrical Certificate of Compliance is a paid form-template add-on per region; OneBookPlus structures the AS/NZS 3000 test readings (insulation resistance MΩ, earth continuity Ω, RCD trip time ms / trip current mA, polarity, visual) into the core CoC form and surfaces one-tap deep-links into each state regulator's lodgement portal (Energy Safe Victoria, Fair Trading NSW, Electrical Safety Office QLD, OTR SA, Building & Energy WA, CBOS TAS, Access Canberra, NT WorkSafe). On top of core, OneBookPlus offers six AS/NZS-aligned marketplace packs that ServiceM8 has no equivalent for: Test & Tag Register ($15/month, AS/NZS 3760), Switchboard Inspection Pack ($19/month, AS/NZS 3000 §8), EV Charger Install Pack ($19/month), Solar Install Pack ($29/month with CEC accreditation guidance and REC Registry STC creation), Heat Pump HWS Install Pack ($19/month with VEU / NSW PDRS / SA HEER rebate workflows), and Emergency Lighting Compliance ($15/month, AS/NZS 2293.2 discharge-test cadence).

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 produces BAS-ready GST figures automatically from your invoices and expenses, so you can lodge or hand them to your accountant without a separate accounting subscription. ServiceM8 has no native accounting, so BAS reporting runs through Xero or MYOB on top of your ServiceM8 plan.

ServiceM8's field app is built for iPhone and iPad only; its own feature overview describes the platform as Apple-focused, and no Android app is offered. Android users can reach the ServiceM8 web dashboard in a browser, but not the native field app your iPhone-carrying teammates use. OneBookPlus runs the full product in any modern mobile browser, on Android or anything else, and also ships a native iOS app.

ServiceM8 holds a 4.5/5 rating from 311 reviews on Capterra Australia. Reviewers praise the ease of use and per-job pricing; recurring criticisms include payment processing fees and support responsiveness. Read the current reviews yourself before deciding, and note that ServiceM8 reviews consistently assume you run Xero or MYOB alongside it for accounting.
