How a 12-person MSP cut six hours a week of invoice reconciliation
A working pattern from an Adelaide MSP that uses ConnectWise Manage as its PSA and Xero as its accounting and payroll system. The numbers, the rituals, and what changed when the manual handling stopped.

We watched a 12-person Adelaide MSP run its month-end ritual for a fortnight last year. The numbers below are real, lightly rounded for narrative. Names have been left out on purpose. What the MSP changed is replicable in any practice that runs ConnectWise Manage plus Xero. The point of writing it up is not that we sold them software. The point is the audit method works without us. Try it on your own books.
Where the six hours actually were
We sat next to the accounts admin for two billing cycles. We counted the time spent on every reconciliation activity, by activity, by week. Here is what we found.
| Activity | Minutes per week | Tool |
|---|---|---|
| Export pending invoice CSV from ConnectWise | 35 | ConnectWise + Excel |
| Retype invoice lines into Xero, reconcile tax codes | 128 | Xero + Excel |
| Look up payment status in Xero, mark paid in ConnectWise | 82 | Xero + ConnectWise |
| Reconcile agreement-billing invoices against the agreement schedule | 68 | ConnectWise + spreadsheet |
| Approve ConnectWise time entries, push to payroll spreadsheet, re-enter into Xero payroll | 59 | ConnectWise + Xero + Excel |
| Total | 372 min | = 6h 12m |
That is one person, one week. Multiply by 48 working weeks, that is 298 hours a year. At an Adelaide accounts admin's loaded rate of AUD $42 an hour, that is AUD $12,500 of human time spent moving data between two systems that do not talk to each other.
Why those activities exist in the first place
The structural reason is simple. ConnectWise and Xero are not natively connected. Every MSP that runs both has built some version of the ritual above. Some use exported CSVs and Xero's import. Some use third-party connectors that handle invoices but not procurement, or invoices but not payroll. Some use their accountants who do the typing as part of the monthly fee. All cost. None of them are the MSP's idea of high-value work.
The honest framing
This is not an automation problem the MSP creates for itself. ConnectWise and Xero are both excellent products in their own right. The cost is the seam between them. Any MSP running both is paying that cost in some form, whether they have measured it or not.
What the MSP changed
The MSP turned on Connect Zero's CW/Xero product. They ran it in parallel with the manual ritual for three weeks to verify the sync moved what they expected. After three clean weeks they retired the manual workflow.
Here is the line-by-line replacement.
- Invoice export and retyping were replaced by Connect Zero's continuous invoice sync. Pending invoices in ConnectWise post to Xero on a six-hour schedule. Tax codes inherit from the ConnectWise location mapping. No CSV touches a human keyboard.
- Payment status writeback was replaced by the bidirectional sync. When a payment lands in Xero, the matching ConnectWise invoice flips to paid automatically.
- Agreement-billing reconciliation was simplified, not eliminated. Connect Zero respects the ConnectWise agreement structure when it syncs invoices, but the accounts admin still reviews mid-period agreement changes. More on that in the "what is still manual" section below.
- Payroll re-entry was replaced by Connect Zero's time-entry-to-Xero-timesheet sync. Approved ConnectWise time entries roll into Xero payroll timesheets per pay period. The accounts admin reviews and approves the Xero timesheets, then payroll runs.
The new ritual, because there is still a ritual
We were honest with them about this and we will be honest here. It is not zero hours. The new pattern is a 20-minute review every Friday morning. Scan the Connect Zero daily summary emails. Action anything sitting in the alerts inbox. Force-sync any urgent invoice that needs to move before the next scheduled run.
20 minutes a week, versus 372 minutes a week. That is a 5 hour 52 minute weekly saving. In annual terms, 282 hours back.
Not zero hours, but most of them back
Any vendor claiming "fully automated" for ConnectWise-Xero reconciliation is overselling, or thinking only about invoices. Real-world reconciliation involves agreement variants, payroll edge cases, and the occasional sync exception. A 95 percent reduction is honest. A 100 percent reduction is marketing.
What this means in dollars
Convert the hours saved to dollars at the Adelaide accounts admin's loaded rate.
| Metric | Before | After | Delta |
|---|---|---|---|
| Reconciliation hours per week | 6h 12m | 0h 20m | 5h 52m saved |
| Reconciliation hours per year (48 weeks) | 298 | 16 | 282 saved |
| Cost at AUD $42/hr loaded | $12,500 | $672 | $11,828 saved |
| Connect Zero Professional tier | n/a | AUD $249/mo | AUD $2,988/yr |
| Net saving | n/a | n/a | AUD $8,840/yr |
The maths assumes the MSP's invoice volume sits within the Professional tier (up to 1,000 invoices per month). At higher volume, the Connect Zero cost rises, but so does the manual saving, typically faster than the cost.
The bits Connect Zero did not fix
Three things still need a human. We will not pretend otherwise.
- Agreement billing variants that change mid-period. When a customer adds seats to a managed services agreement on the 15th of the month, the ConnectWise agreement schedule updates but the existing pending invoice does not always re-price cleanly. The accounts admin still reviews these.
- Unusual leave applications that do not map to a Xero leave type. Personal leave, annual leave, long service leave: those map cleanly. One-off arrangements (compassionate, time-in-lieu) sometimes need a manual mapping update before the sync handles them.
- Mid-week time-entry edits. Connect Zero alerts on these and replays them on the next cycle, but the accounts admin still glances at the alerts inbox to confirm the change was intentional, not a mis-edit.
What you still do yourself
Treat this list as the floor of what stays manual. Connect Zero handles the rhythm. The human handles the exceptions. That is the right division of labour in our view.
How to run the same time-audit on your own MSP
You do not need to be a Connect Zero customer to do this. Six steps, runs in two weeks.
- Pick one billing cycle. Two weeks if you bill weekly, one month if you bill monthly.
- List every activity your accounts person does that involves moving data between ConnectWise and Xero in any direction. Be specific. "Reconciliation" is not granular enough.
- For each activity, time-track it. Five days of stopwatch is enough. Round to the nearest five minutes.
- Sum the minutes per week. Convert to a percentage of one full-time week (38 hours = 2,280 minutes).
- Convert the minutes to dollars at your accounts person's loaded hourly rate. Loaded means salary plus on-costs (superannuation, leave loading, workspace overhead). For an Adelaide accounts admin this is typically 1.3 to 1.5 times the bare hourly rate.
- Compare the annual figure against the published price of every connector on the market, plus your own opportunity cost. The maths usually picks the answer for you.
If you want to compare your numbers
If you want a second pair of eyes on the maths, the Connect Zero team will do the calculation with you on a Teams call. We have done this for several MSPs that ended up not buying Connect Zero, because the volume did not fit. Either way is fine. Plain audit, no pitch.
