Your bank balance shows you where you are. Parallel shows you where you’re headed, what could change your trajectory, and how much time you have to respond.

Your bank account tells you how much cash you have. Your accounting software tells you what happened last month. Neither tells you what happens if revenue slips, hiring accelerates, or a major customer churns.
This is where cash flow management becomes a planning problem. To manage cash effectively, you need: a clear view of today’s position, a forecast of where you’re headed, and a way to test the impact of decisions before you make them.
Most startups spend hours trying to do all this in a spreadsheet. Eventually the model falls out of date, confidence disappears, and decisions start getting made without clarity.
Parallel takes you out of the spreadsheets and brings back certainty by showing you a clear picture of current and future cash flow. No need to build and rebuild spreadsheets, and no more uncertainty about what your cash situation really is.
Connect QuickBooks Online or Puzzle. Your cash inflows and outflows sync in automatically, and your cash flow forecast updates as your books do.
Deferred revenue, accounts receivable, and contract structure all affect when cash arrives. Parallel reflects real cash timing so you can plan more accurately.
Decide with a full financial picture, not just your gut. Run what-if scenarios and compare them side by side without changing the core model.
Every change to cash flow shows up in runway. Adjust hiring, spending, collections, or revenue assumptions and see the impact immediately.




Future cash starts with future revenue. Parallel will create a model with the growth drivers that matter most to your business, allowing you to easily see how they affect cash flow over time.
Expansion, contraction, and churn shape how much revenue stays in the business over time. Small changes in retention compound, dramatically affecting future cash flow.
The timing of payment matters as much as the revenue itself. Invoice terms, payment delays, and contract structure determine when cash actually reaches your bank account.
For most startups, payroll is your largest expense category. Every hiring decision creates an ongoing cash obligation through salary, benefits, taxes, and other employee costs.
Software, infrastructure, marketing, contractors, and professional services all contribute to cash outflows. Some expenses are fixed, while others scale with growth.
Fundraising, debt financing, and other capital events can materially change your cash position, extending runway and reshaping future planning decisions.

It’s software that helps you see your cash position, forecast it forward, and model the decisions that change it. Unlike spreadsheets or accounting software alone, modern cash flow management software connects to your accounting, updates automatically, and lets you run scenarios on top of your real data.
Accounting software like QuickBooks and Puzzle records what already happened, whereas cash flow management software shows what's happening next. They work together: Parallel builds reports on top of your accounting actuals and uses them to power the cash flow forecast.
Parallel pulls your historical cash inflows and outflows from your accounting software, then projects them forward using your assumptions about revenue growth, expenses, hiring, and capital movements. The forecast reflects what's in your books and updates as new actuals come in.
In practice, the terms are used interchangeably. Both refer to a forward-looking view of cash inflows and outflows. Parallel produces both: The live forecast updates automatically, and you can export a static cash flow projection for an investor data room.
No, Parallel was designed for SaaS founders without a finance background. Every input is built on sensible defaults.

Accurate enough to make decisions against. The forecast is grounded in your real accounting data and assumptions. As actuals come in, the forecast updates so you can see exactly where reality is diverging from your model. The point isn't perfect prediction but clear direction.
It depends on how your accounting is set up. If you use an accrual basis, Parallel forecasts the same way. If an annual expense lands as a single payment, Parallel can either treat it as a one-time event that recurs on the same cadence or take an average over time. Either way, the expense is captured even if the timing isn't exact, and your monthly burn doesn't get inflated by a single-time payment.
Parallel keeps your cash flow forecast current. You always know where your money's going today, what's coming next month, and what you can change to maintain a strong cash position.
