Billtwin vs HubSpot's QuickBooks and Xero sync
These are two different jobs. HubSpot's own sync moves invoices, contacts, products and payments between HubSpot and your accounting system. Billtwin does not sync anything: you give it a HubSpot invoices export and a Xero or QuickBooks Online export and it lists every invoice that is missing, booked twice or different. A sync that is running can still drift, which is where a check helps. HubSpot's side was read from its pages on 6 November 2026.
Side by side
| HubSpot's QuickBooks Online and Xero syncs | Billtwin | |
|---|---|---|
| What it does | Keeps contacts, products, invoices and payments in step between HubSpot and QuickBooks Online (HubSpot) or Xero (HubSpot), with the direction set per object | Compares two exports and lists every invoice that is missing in the books, booked twice, or different in total, currency, customer, voided state or payment status, sorted by money at risk |
| Changes your records | Yes, that is the point: it writes to both systems | No. It changes nothing in HubSpot, Xero or QuickBooks; its HubSpot and Xero connections are read only, and QuickBooks Online is checked from its export |
| Finding gaps | HubSpot's page describes sync status in record views, and no tool to compare or reconcile your two sets of invoices | Shows the row number on both sides and a fix for each difference |
| Known limits | HubSpot lists some: invoices created in HubSpot must be edited in HubSpot, credit card fees do not sync, the Xero sync supports six currencies, and QuickBooks Online accounts that need tax on invoices cannot use it | Only compares invoices. Connected daily monitoring is a pilot, not a finished feature |
| Timing | Near real time: HubSpot to QuickBooks changes within minutes, QuickBooks to HubSpot every 30 minutes, with a Sync now button | When you run it, for example before month end close |
| Set up | From inside HubSpot; Super Admin or App Marketplace permissions are needed, and changing the default field mappings needs Data Hub Starter or higher | Drop in two files in the browser; they are read in your browser and never uploaded |
| Price | The HubSpot pages state no price for the sync; HubSpot says it is available with all HubSpot products and plans, and extra subscriptions may be needed for some features | Free up to 150 HubSpot invoices per run; Pro is $299 a month or $2,990 a year with no invoice limit |
Which one fits
- You need invoices to flow between HubSpot and the ledger: HubSpot's own sync is the first-party route, runs all day and is built into HubSpot. Billtwin does not replace it.
- You already sync, or you copy invoices by hand, and the totals do not agree: a controller or bookkeeper running a check before close wants a list of what is missing, doubled or different, with the money at risk first. That is Billtwin.
- You are a HubSpot partner taking over a client whose books and CRM have drifted: run the check first, then decide what to fix.
