One of the main reasons Australian electrical and solar businesses choose ServiceM8 is its Xero integration — invoices generated in the field sync to Xero automatically, payments flow back, and the two systems stay in sync without manual data entry.

For electrical contractors, this isn’t just about convenience. Under the Fair Work Act 2009, employers must maintain accurate time and wage records for 7 years. The Australian Taxation Office requires GST-compliant invoicing with correct ABNs and tax codes. A properly configured ServiceM8-Xero integration means every invoice is compliant at source — no end-of-month reconciliation panic, no missing records if Fair Work or the ATO audits.

This guide walks through how to set it up, what syncs and what doesn’t, and how to get the most from the integration.

Why the ServiceM8–Xero Integration Matters

For most trade businesses, the accounting bottleneck is the gap between completing a job and getting paid. Without integration, the process looks like this:

1. Job completed on Thursday
2. Job notes and time come back to the office
3. Admin creates an invoice in Xero on Friday or Monday
4. Invoice sent Tuesday (or later)
5. Payment terms start from invoice date

With ServiceM8–Xero integration, the process is:

1. Job completed on Thursday
2. Technician invoices on-site from their phone
3. Invoice appears in Xero immediately
4. Payment terms start from Thursday

The reduction in billing lag — typically 2–7 days — directly improves cash flow. On $50,000/month revenue, getting paid 5 days earlier is meaningful.

Setting Up the Integration

Step 1: Connect ServiceM8 to Xero

1. In ServiceM8, go to Settings (gear icon) → Integrations
2. Select Xero from the integration list
3. Click Connect to Xero
4. You’ll be redirected to Xero’s login page — sign in with your Xero credentials
5. Authorise ServiceM8 to access your Xero organisation
6. Select the correct Xero organisation if you have multiple
7. Click Allow access

You’ll be returned to ServiceM8 with a green “Connected” status. The integration is now live.

Step 2: Configure tax and account codes

Once connected, ServiceM8 needs to know which Xero account codes to use for different line items:

1. In ServiceM8, go to Settings → Integrations → Xero
2. Map your ServiceM8 tax rates to the corresponding Xero tax codes (GST, GST Free, BAS Excluded)
3. Set the default Xero account code for invoiced work (typically your income account — e.g., 200 Sales)
4. If you have different service types (labour, materials, callout fees), configure separate account codes for each

Tip: Use Xero’s chart of accounts to set up separate income accounts for labour and materials before connecting. This gives you cleaner P&L reporting — you’ll see labour income and materials income separately without manually categorising.

Step 3: Check client record sync

Existing clients in ServiceM8 will be matched to existing Xero contacts by name or email. Review the match suggestions in the integration settings and confirm any that look incorrect.

New clients created in ServiceM8 are automatically created in Xero. New contacts created in Xero are available in ServiceM8 when you search for a client.

What Syncs — and What Doesn’t

What syncs ✅

Data type	Direction	When
Invoices	ServiceM8 → Xero	When invoice is sent from ServiceM8
Invoice status	Xero → ServiceM8	When payment is reconciled in Xero
Client contacts	Both ways	When created or updated
Payments	Xero → ServiceM8	After bank feed reconciliation
Credit notes	Xero → ServiceM8	When credit note is applied
Tax codes	Xero → ServiceM8	During setup configuration

What doesn’t sync ❌

Data type	Notes
Quotes	Quotes live in ServiceM8 only. Only invoices push to Xero
Job records	Job details, forms, photos stay in ServiceM8
Purchase orders	ServiceM8 POs don’t push to Xero automatically
Payroll	Managed separately in Xero Payroll or your payroll system
Time tracking	Time in ServiceM8 is converted to labour line items on the invoice — raw time data stays in ServiceM8

Getting the Most From the Integration

Invoice on-site, every time

The integration only delivers its full benefit when technicians invoice from the field on completion, not from an office later. Set a clear workflow expectation: job finished = invoice sent before leaving the site. Most technicians adopt this quickly once they see how fast ServiceM8 makes the process.

Use Xero’s bank feed for reconciliation

With invoices in Xero, bank feed reconciliation becomes straightforward — Xero automatically matches incoming payments to outstanding invoices. The payment status then flows back to ServiceM8. This replaces manual “mark as paid” steps in both systems.

Set up payment terms in both systems consistently

Configure your payment terms (e.g., 7-day or 14-day) consistently in both ServiceM8 (under business settings) and Xero (under your invoice settings). Inconsistency creates confusion when following up overdue invoices.

Use ServiceM8’s automated payment reminders

ServiceM8 can send automated payment reminder emails to customers with overdue invoices. Since Xero’s payment status flows back to ServiceM8, ServiceM8 knows when an invoice is paid and stops the reminder sequence automatically. Enable this in ServiceM8’s settings to reduce manual follow-up.

Separate account codes for labour and materials

If you’re billing labour and materials separately (which most electrical businesses should), configure separate Xero account codes in ServiceM8’s integration settings. This means your Xero P&L shows:

• Labour income (200-ish)
• Materials income (separate)
• Any subcontractor costs on a separate expense account

This granularity is useful for tracking margin by job type and benchmarking against industry norms.

Common Issues and Fixes

Problem	Likely cause	Fix
Invoices not appearing in Xero	Integration disconnected (Xero tokens expire)	Re-authenticate via Settings → Integrations → Xero
Duplicate contacts in Xero	Client name in ServiceM8 doesn’t exactly match Xero	Manually merge in Xero, then re-link in ServiceM8
Wrong tax rate on invoices	Tax code mismatch between ServiceM8 and Xero	Re-check tax code mapping in integration settings
Payment not updating in ServiceM8	Bank feed reconciliation not done in Xero	Reconcile in Xero first — update flows to ServiceM8 shortly after
Invoice in wrong Xero account	Default account code not set correctly	Update default account code in ServiceM8 integration settings

ServiceM8 + Xero vs Other Combinations

Combination	Verdict
ServiceM8 + Xero	✅ Best option for most Australian electrical/solar businesses
ServiceM8 + MYOB AccountRight	✅ Good — native integration, similar depth to Xero
ServiceM8 + MYOB Essentials	✅ Available — slightly less functionality than AccountRight
ServiceM8 + QuickBooks Online	✅ Available — less common in Australia
ServiceM8 + no accounting software	❌ Not recommended — manual invoicing is a major efficiency gap
Xero only (no job management)	❌ Not recommended — Xero is not built for trade job management
