For bootstrapped SaaS

Test the next move before it spends your runway

You grow on your own revenue, so a hire either pays for itself or doesn't happen. Your accounting and three subscription numbers you already know become one baseline: MRR, burn and runway if nothing changes. Then stack the hire, the acquisition budget or the price move on it and see what each one costs in months — and when it earns itself back.

Trusted by bootstrapped SaaS teams

The status quo

Your dashboards say where you are, not where you're heading.

You know MRR, churn and CAC to the decimal. What none of them answers is the next decision — hire, raise the budget, change the price — because none of them runs forward far enough to hold it.

How fast is your MRR actually growing?

You know today's number to two decimal places. Where sign-ups and churn carry it in six months is written down nowhere.

MRR in six monthsThe month churn outruns growth

Does your growth pay for itself — and what's the cheapest way to it?

ROAS doesn't answer that for subscriptions: a customer pays for years, the measurement covers a month. And whether a hire moves faster than more budget, nobody knows either.

Real CAC paybackA hire vs. more budget

Where is the money going — and what is changing it worth?

Tools, hosting, salaries: each line looks small on its own. What a change buys you in runway is something nobody works out in advance.

Push a hire back two monthsCloud budget −20%

What's missing is a base that runs forward in months, not metrics — and holds still while you test a decision against it.

The challenge

Why decisions in a subscription business are so hard to call

Six things make a subscription business hard to read. Anything you want to decide against has to handle every one of them first.

Recurring revenue is a base, not a monthly figure

It rebuilds every month: last month's customers, minus churn, plus sign-ups, times ARPU. Extending this month's number by a growth rate misses the compounding entirely.

Churn compounds quietly

Two percent a month sounds like nothing. Over a year it takes a fifth of your base, and the month it starts outrunning sign-ups doesn't announce itself.

A customer pays for years, the spend happens in one month

ROAS measures revenue in the month you spent. For a subscription that window is wrong by design, so every healthy acquisition looks like a loss.

Annual plans break cash away from profit

One payment arrives in January and is earned across twelve months. Cash and profit genuinely disagree, and a plan that only shows one of them is wrong half the time.

Payroll steps, it doesn't slope

A hire changes the burn from their first month at full cost, including employer contributions — while the output they add arrives months later.

Runway is a date, not a division

Cash divided by average burn hides the months where a tax payment, an annual renewal and a hire all land together. The real answer is a day in the cash curve.

So it takes more than a spreadsheet. It takes a base that handles all six by design — and holds up when you test a decision against it.

The solution

One model of your subscription business — and every decision tested on it

Foreqast isn't three separate tools. It's one model of your subscription business — prebuilt from your accounting data, sharpened by every driver that syncs into it, and built to be the thing your next decision gets measured against.

How Foreqast solves it

Recurring revenue isn't a monthly figure you extend — it's a base that rebuilds every month: last month's customers, minus churn, plus sign-ups, times ARPU. Foreqast models exactly that from three inputs you already know. Change one and you don't just get a new number, you get the slope: how fast it climbs, and the point where churn starts eating the growth.

Buying growth

Model advertising the way a subscription business actually works.

How Foreqast solves it

For subscriptions, Foreqast plans advertising on CAC rather than ROAS — the number you actually have. ROAS measures revenue in the month you spent it, but your customer pays for years: at €220 to acquire against a monthly ARPU, every healthy acquisition would look like a loss. CAC runs the other way round: budget ÷ CAC gives sign-ups, the sign-ups join the customer base, and the base keeps billing month after month. You see the 36 customers the budget buys and the roughly 4.5 months until they've paid for themselves. Whether an extra hire moves faster than more budget is tested beside it, on the same model.

Tools, hosting, salaries: every recurring block is its own line and every change its own switch. A cancelled subscription, a delayed hire, a smaller budget — turn them on alone or together and compare the forecast with and without. The switch above the table gives you both sides of it: the profit view says what the month actually earns, the cash view says what the saving buys you in months of runway.

Set up in 15 minutes — after that you decide on live numbers

It takes one guided setup: a handful of questions about how your subscription business works, and your accounting connected. Foreqast generates the forecast from there — no model to build, no template to fill in. From that point on, every decision has a number behind it.

15 min
Complete the guided setup
Foreqast asks how your subscription business earns and spends — plans, churn, acquisition, payroll and contracts — and you connect your accounting. That is the whole setup.
Automatic
Your forecast is generated
Your bookings arrive already categorized, get accrued day by day and roll twelve months forward. The forecast builds itself — and stays current with every sync.
From day one

Burn, runway and your subscriber base are there. Test the hire, the acquisition budget or the price change against them before you commit.

Usable from the guided setup alone, sharper with every step after it: billing and payment integrations · acquisition channel syncs · the hiring plan · contracts and cloud spend

Why Foreqast

All the data, none of the finance department

A spreadsheet holds every number you put in it — and you maintain every one of them, until the first model change breaks it. An FP&A suite can do everything, but it costs an implementation project. Foreqast joins the two: the data from your accounting, carried forward automatically, and a decision you can switch on and off against it.

	Spreadsheets	Enterprise FP&A	Foreqast
Data basis	Anything you type in	After the implementation	Real accounting data
Recurring revenue model	40 formulas you maintain	Fully modelled	Three inputs, prebuilt
Churn & customer base	If you build the roll-forward	Down to cohorts	Base, churn and sign-ups
CAC & payback	In a second sheet	Available	Budget ÷ CAC into the base
Runway as a date	A monthly average	Monthly granularity	Day by day, always current
Cash and profit view	Whatever you model	Both, maintained apart	Both, one switch apart
Testing scenarios	A copy of the file	Versioned scenarios	Switches, compared live
Upkeep a week	Around 8 hours	A role of its own	Fully automatic
Setup	Days to weeks	An implementation project	20 minutes
Price	Free	Five figures a year	From €39/month

The short version: a spreadsheet has the flexibility, but you maintain it. The FP&A suite has the depth, but not your budget or your time. Foreqast has the subscription model already built — and costs less.

FAQ

The questions founders ask

What software teams want to know before they start — answered briefly. The long version lives in the documentation and the academy.

Still have a question?

The documentation explains every field; the academy walks the whole way from actuals to a finished plan.

Read the documentation Academy: the cash flow course Explore losing a client

Do I need a CFO for this?

No — that's the point. The structure comes from your accounting, and the subscription model from three inputs you already track.

Why accounting instead of a bank feed?

Because bookings arrive already assigned to an account. Nothing needs categorizing, and your plan uses the same numbers your accountant does.

Can I model cohorts?

Today you plan with new customers, churn rate and ARR per customer. Cohort-level modelling is on the roadmap.

How is runway calculated?

From the day-by-day cash forecast, not a monthly average — including contracts, payroll and any planned hires.

How do you handle annual plans?

The payment lands on its real date and the revenue is accrued across the term. The switch above the table gives you both sides of it.

Why CAC instead of ROAS?

Because ROAS measures revenue in the month you spent, while your customer pays for years. On CAC, the sign-ups you bought join the base — and the base keeps billing.

Can I plan a hire before it's signed?

Yes. A planned role gets a start month, salary and workload and runs in the forecast from that month — employer contributions included.

What about investor reporting?

Burn, runway and the cash plan are always current and exportable, so there's no rebuild before every update.

Does it work with Stripe subscriptions?

Yes. Stripe delivers actual revenue, refunds and fees; your subscription model plans forward on top of it.

Is my data secure?

Your data is encrypted in transit and at rest, and only ever used to build your own forecast.
