Built around the way finance teams actually work
Most companies don’t close their books on the first of the month. That’s why Parallel waits until your close is complete before syncing actuals into your model. Syncs run automatically based on your close schedule, and you can refresh at any time to pull in the latest data.
The detail comes through too: Vendor-level spend, accounting categories, cash flow activity, and balance sheet data all flow directly into Parallel so you can investigate what’s driving changes without jumping between systems.
If you use classes in QuickBooks Online or Puzzle, Parallel automatically maps them for departmental reporting. And because your forecasts should reflect your accounting reality, expenses follow the same cadence they’re on in your books, whether that’s a monthly accrual or a once-a-year payment.

Frequently asked questions
How long does it take to connect my accounting?
The initial OAuth flow takes 1-2 minutes. After that, Parallel pulls your historical actuals and auto-builds your three-statement model. Every future sync runs in the background and takes about 30 seconds.
What if I use Xero or another accounting tool?
Outside of Quickbooks and Puzzle, parallel doesn’t support any other accounting software today. If your books live elsewhere, let us know so we can prioritize it in our integration roadmap. In the meantime, founders running other accounting tools sometimes shadow their books in QuickBooks Online or Puzzle so they can gain access to Parallel’s financial forecasting capabilities.
Will Parallel write back to my accounting software?
No. Parallel reads from your accounting and produces a forecast on top of it. Your bookkeeping stays in your accounting software and Parallel doesn’t edit or overwrite it, ever.
How often does the sync happen?
The sync runs on a configurable day each month, defaulted to the 20th, so your books have time to close before actuals flow in. You can adjust the date they pull or trigger a resync any time you need to.
What data does Parallel have access to?
Parallel reads the financial information stored in your accounting platform including revenue, expenses, balance sheet accounts, cash flow activity, vendor data, and accounting categories.
That information is used to build and maintain your forecast, and allow you to dig into vendors, categories, and departments directly inside Parallel without switching back to your accounting software.
