ConnectWise to Xero sync for government MSPs

Government MSPs deal with PO-matched invoicing, FAR-style compliance language, and net-30+ payment rhythms that stretch into net-60 on larger contracts. Connect Zero posts ConnectWise invoices into Xero with PO references intact, so your government clients can match against their procurement system without manual lookup.

What this page covers

If you run a government MSP on ConnectWise and Xero, you already know your billing rhythm is different from a generic break-fix shop. Your government clients pay against purchase orders. Their procurement teams reconcile invoices against PO numbers, not vendor names. A Xero invoice that arrives without the PO reference in the right field is a thirty-day delay while it sits in someone’s exceptions queue. Connect Zero is built for that pattern, not against it.

Why government MSPs hit a wall with manual ConnectWise to Xero billing

Government MSPs we talk to describe a procurement workflow that goes: PO issued by the agency, work performed, invoice raised in ConnectWise with the PO number, invoice manually re-keyed into Xero with the PO number put in the reference field. If the bookkeeper drops the PO number, the agency’s accounts-payable system rejects the invoice and it sits for thirty days while someone investigates. Cashflow on government contracts is fragile enough without that.

The four forces driving the switch, as we hear them on calls:

Push: A government invoice that bounced because the PO number was missing from the Xero reference, then sat in the agency’s exceptions queue for three weeks while the MSP chased it.
Pull: A Xero invoice that carries the PO number in the reference field every time, with no manual re-keying step where the number could be dropped.
Habit: The bookkeeper’s mental checklist of “PO number first, then amount, then GST”. Reliable when the bookkeeper is there. A liability when they are not.
Anxiety: Worry that automation puts the PO number in the wrong field or strips formatting that the agency’s AP system expects. The dry-run report lets you see exactly what would post, in exactly what format, before any live write.

How Connect Zero handles government-specific billing

Connect Zero reads the PO number from the ConnectWise invoice and writes it to the Xero invoice reference field, preserving exact format. For agencies that need the PO in a custom field, Connect Zero supports Xero custom fields by name. Continuous sync means the invoice arrives at the agency’s AP system the same day it is approved in ConnectWise.

The vertical-aware mappings that matter

ConnectWise invoice PO number written directly to Xero invoice reference field, character-for-character
ConnectWise agreement “Federal Contract FY26” tagged into Xero tracking category “Contract”
ConnectWise company “Department of Health” mapped to Xero contact group “Federal Agencies”, so net-60 payment terms apply automatically

5-step install

Connect ConnectWise. OAuth into your ConnectWise Manage tenant. Read-only at first so you can review what Connect Zero sees before any sync writes a thing.
Connect Xero. OAuth into your Xero organisation. If you run multiple Xero files for different entities, connect each one and Connect Zero will route invoices by ConnectWise company.
Map locations and departments. Walk through ConnectWise locations and pick the matching Xero tracking categories. For government MSPs the single mapping that earns its keep is PO number preservation, end-to-end, no manual re-key. Get that right and your invoices clear AP exceptions queues on the first pass.
Run a dry sync. Connect Zero produces a side-by-side report of what would post to Xero on the next cycle. Review it, flag corrections, then approve.
Switch to live sync. Once you approve, Connect Zero runs continuously. New ConnectWise invoices appear in Xero within minutes, status updates flow back, no manual re-keying.

Frequently asked questions

Does Connect Zero preserve PO numbers exactly? Yes, character-for-character. We read the PO number from the ConnectWise invoice and write it to the Xero reference field without trimming, padding, or reformatting. If your agency expects a specific format like “PO-2026-00123” with hyphens, that is exactly what reaches Xero.

What about FAR compliance requirements on the audit trail? Connect Zero maintains a full audit log of every sync action: when it happened, what was read from ConnectWise, what was written to Xero, and who in the MSP team approved the underlying ConnectWise invoice. That log is exportable for any audit conversation.

Can I handle net-60 or net-90 payment terms differently from net-30 clients? Yes. Map the ConnectWise company to a Xero contact group and apply payment terms at the Xero contact-group level. Every invoice for that agency picks up the longer terms automatically.

What if the agency uses a procurement portal like SAP Ariba or Coupa? Connect Zero posts to Xero. If the agency’s procurement portal imports from Xero, the import gets the PO reference Connect Zero put there. Direct integration to procurement portals is a separate conversation.
