Plus support when you need it
We are a small team with a rapidly growing SaaS business, and we need all the automation we can get. Invoice Stack is just what the doctor ordered - provides seamless integration from our HubSpot quotes directly into Xero invoices.
We now can see live invoice status directly on each deal!
It has made invoicing so much easier. This was a better alternative than the Xero owned invoicing App. Would recommend it for any business. I love that all tracking and personalisation are done in HubSpot saving the double handling of invoices.
Really stoked to have found an app that builds the bridge from HubSpot - Xero - A well considered app that honestly has taken hours off admin time making our sales team sell with no friction.
Utterly fantastic invoicing solution if you're using QuickBooks. We use this in conjunction with invoices/line items generated in PandaDoc and synced to HubSpot, and it works great.
Makes the process more efficient, less re-keying, fewer errors. Direct 1-1 support very helpful too.
It's done everything we need it to do - the personal support from Harry who heads up the business has been greatly appreciated too.
Six months on, and it has been smooth-sailing for our Finance team and the quote-to-invoice process has never been this streamlined.
Literally the best plug-in for HubSpot to Xero invoicing! Everything is clean and immediate, automatically allocates the quoted items into invoices - amazing design and easy to use.
