MSP billing software with time tracking: PSA options that sync to Xero and QuickBooks
The best MSP billing software with time tracking is a PSA that turns logged time into invoice lines without anyone retyping it: HaloPSA and ConnectWise PSA for depth and native Xero sync, Syncro and SuperOps for simpler all-in-one billing. The right pick depends on three things: how your recurring contracts are structured, whether you sell blocks of hours, and whether your accounts live in Xero or QuickBooks Online. Here is how to choose, criterion by criterion.
The spreadsheet is not the problem. The re-keying is.
Billing from a spreadsheet works until it does not. Technicians log time in one place, someone copies it into a sheet at month end, someone else copies the sheet into the accounts package. Each copy is a chance for an hour to fall out of the gap between time logged and time billed.
That gap rarely shows up as an error. It shows up as quiet leakage: the 20-minute call nobody logged against a ticket, the out-of-scope work absorbed into a contract because nobody noticed the allowance was spent, the project hours that sat unbilled for a quarter. A spreadsheet is a guess wearing a ledger's clothes.
It is also the exception. According to Paidnice, most MSPs bill from their PSA (ConnectWise PSA, Autotask, HaloPSA, Kaseya BMS, Syncro or SuperOps) and sync invoices to QuickBooks Online or Xero. If you are new to the category, our explainer on what a PSA actually does covers the basics.
What MSP billing software with time tracking must do
Integration logos tell you almost nothing. Three capabilities decide whether a tool closes the gap.
- Model recurring contracts properly. A managed services agreement is usually a fixed monthly fee, often per user or per device, plus exclusions. The PSA should generate that invoice line automatically and adjust it when the device or user count changes. Skip this and you are back to updating quantities by hand.
- Track hours allowances. If you sell ten hours a month or prepaid blocks, the tool must draw down time entries against the allowance, show the balance, and bill overage at the right rate. Skip this and overage becomes goodwill nobody agreed to give.
- Sync to the accounts package without retyping. Invoices, customers and ideally payment status should move between the PSA and Xero or QuickBooks. Skip this and your finance lead keeps a second copy of every client.
The month-end test: pick one client with a contract, an hours block and one ad hoc project. In a trial, log a week of mixed time against them and generate the invoice. If you have to touch a spreadsheet at any point, the tool has not closed the gap.
PSA billing compared: contracts, hours and Xero sync
Pricing below is in US dollars as published on third-party listings; check the vendor's own page before you budget.
| PSA | Recurring contracts and hours | Xero sync | Listed price |
|---|---|---|---|
| HaloPSA | Deep, highly configurable contract and allowance rules | Native, with webhooks | From $119 per user a month |
| ConnectWise PSA | Mature agreements model with additions and allowances | Native two-way | Not published |
| Autotask | Contract types including recurring service and block hours | Check current options before buying | Not published |
| Syncro | Simpler recurring invoices and prepaid hours | Check current options before buying | $129 per user a month (Core, with RMM) |
| SuperOps | Contracts with automated billing and invoicing | Check current options before buying | $79 a month (Standard PSA-only) |
HaloPSA: the deepest Xero integration, at a configuration cost
HaloPSA treats Xero as a first-class citizen. Per HaloPSA, its Xero integration can subscribe to Xero webhooks so customers are automatically created or updated whenever they change in Xero, and invoice paid dates can be set automatically in HaloPSA. It can also import accounts from Xero, with the Account Codes module automatically setting the tax rate linked to each accounts code for items. Capterra lists its official starting price at $119 per user per month for its all-in-one plan, which includes all features, with pricing varying by team size. The catch is setup effort, which we cover in HaloPSA alternatives: the configuration tax.
ConnectWise PSA: native two-way sync, enterprise weight
According to FlexPoint, ConnectWise PSA offers native two-way syncing with Xero that can automatically push tickets, time entries and agreements between the two systems. Its agreements model is mature. It is also a large product with quote-based pricing, which suits larger teams better than a three-technician shop.
Syncro and SuperOps: simpler billing, fewer knobs
G2 lists Syncro's Core plan, which combines RMM and PSA, at $129.00 per month per user with unlimited RMM agents for Windows and Mac devices, and SuperOps' Standard PSA-only plan at $79.00 per month including ticketing, projects, and automated billing and invoicing. Both are easier to stand up than HaloPSA. Where an accounting connector is not native, MSPs typically bridge it with middleware such as PSA-Sync or an n8n workflow, which works but adds one more thing to maintain.
Autotask: solid contracts, confirm the Xero route
Autotask has long handled recurring service contracts and block hours well. Its accounting integrations have historically leaned towards QuickBooks, so a UK buyer should confirm exactly how Xero sync works today before committing.
Why Xero support matters more in the UK
Xero is widespread among UK small businesses and their accountants, so many UK MSPs already run on it. The ecosystem is also larger: one Xero vs QuickBooks comparison puts Xero's App Store at over 1,000 third-party integrations against QuickBooks' roughly 650. That breadth means middleware usually exists if your PSA lacks a native connector, but native beats bridged because there is one fewer failure point at month end.
Rule of thumb: if you sell hours blocks and invoice in Xero, insist on native sync of invoices and customers. Middleware is fine for the occasional edge case, not for the core billing run.
Failure modes: how each option goes wrong
- Deep PSA, half configured. You buy power and never finish setup, so contracts still get adjusted by hand.
- Simple PSA, complex contracts. Your agreements outgrow the tool and exceptions drift back into a spreadsheet.
- Middleware sync. It works until an API change breaks it silently, and nobody notices until invoices are missing.
- Per-user pricing growth. Every technician you hire raises the bill, which our piece on vendors that publish flat pricing examines in detail.
Where this fits with Helios
Helios includes ticketing, time tracking and client billing in the same product as monitoring and patching, so time logged against a ticket is already where the invoice is built. Every feature is on every plan, from £20 a month, with 14 days free and no card to start. Most of the gap between time logged and time billed is discipline, not tooling: technicians still have to log their time. If you want to run the month-end test above on your own clients, you can compare Helios with the major PSAs first and then trial it.
Common questions about MSP billing software
Does HaloPSA integrate with Xero natively?
Yes. HaloPSA has a native Xero integration that can import accounts, set tax rates through account codes, subscribe to Xero webhooks so customers stay updated, and set invoice paid dates automatically. That makes HaloPSA one of the stronger choices for UK MSPs that already keep their books in Xero, provided they budget time for configuration.
Can I keep billing from a spreadsheet if I add a PSA?
You can, but a PSA bought only for ticketing while billing stays in a spreadsheet keeps the re-keying step that causes most leakage. The value of MSP billing software with time tracking comes from invoices being generated directly from contracts and time entries, then synced to Xero or QuickBooks without copying.
Is middleware like n8n good enough for Xero sync?
Middleware such as n8n or PSA-Sync can connect a PSA to Xero when no native integration exists, and it works well for many MSPs. The risk is maintenance: an API change can break a workflow quietly. Native sync is the safer choice for the core monthly billing run.
