From the Business Plan to the Budget: the financial management that helps a startup grow

In a startup, the problem is almost never the idea: it is understanding if the numbers actually back it up. Yet, many still treat the Business Plan as a formal document to be presented to investors, rather than the first true tool for business control. It is there, in fact, that project sustainability is measured, financial needs are estimated, and the KPIs that will guide future decisions are set from the very beginning. Without this step, talking about growth often means flying blind.

What is a Business Plan?

In a startup, the Business Plan represents the numerical "translation" of the growth path you intend to take. The primary goal is to verify whether business assumptions have a positive impact on the figures, both in terms of expected profitability and, above all, cash flow.

A Business Plan provides answers to questions such as: How much liquidity do I need to carry out my investments? What is the timeline for triggering further investments? Additionally, it is essential for setting all those KPIs that must be monitored from day one (CPL, CAC, churn rate, etc.).

Understanding your business and the nature of the costs and revenues you will record allows you to adopt an explanatory reclassification of accounts from "Day Zero." This will be of immense help during later stages of reporting and management control.

While a Business Plan typically covers a 5-year horizon, it is useful to set it up on a monthly basis, as the first 12–24 months form the foundation for drafting the Annual Budget.

What is the Annual Budget?

The Annual Budget is an operational document used to monitor the trend of costs/revenues and inflows/outflows, typically over a 12–24 month horizon.

It takes its cue from the Business Plan but, unlike the latter, the Budget accounts for both the chosen growth path and the actual results achieved on a weekly or monthly basis. Especially in the early stages of a startup's life, it is vital to constantly monitor cash inflows and outflows and compare them against both the Budget and the Business Plan.

For this reason, it is important to adopt a consistent and uniform reclassification of all items to compare objectives with real-world data.

Furthermore, it is fundamental for a startup to be able to pivot quickly, either to adapt to market changes or to validate specific assumptions. Having a Budget that factors in both actual data and short-to-medium-term forecasts represents a powerful tool of awareness and utility for all startup decision-makers.

Common Mistakes

To ensure accurate cash flow forecasting, it is crucial to update the annual budget at least monthly.

One important item to monitor is VAT. For early-stage startups, VAT has a significant impact. Typically, startups in their initial phases incur far more costs than revenues. This dynamic generates a negative impact on cash flow, as the startup will likely record VAT credits (but immediate outlays) in the early stages. This higher cash pressure is even more significant when expenses are tied to external suppliers. In this case, estimating the VAT impact—and even more so the timeline for its recovery—becomes vital.

Additionally, it is important to account for all financial flows that have not yet been realized, typically receivables and payables. Specifically, being able to monitor certain debt items related to personnel (e.g., severance pay/TFR, holidays, and leaves) can prove fundamental during moments of financial stress.

It is no coincidence that cash monitoring is one of the top priorities within our startup studio. For this reason, we have structured ourselves with an administration team and AI tools to map and monitor all flows on a daily basis. This activity is essential to allow management to analyze performance trends and, most importantly, update the prospective budget monthly based on the results achieved in the previous month.

Conclusion

Building a Business Plan consistent with the startup's development logic and the subsequent monitoring of the annual budget is a distinguishing factor for proper corporate management. It also serves as an element of transparency and trust for shareholders and investors.

Being able to monitor cash flow trends and their prospective evolution—while keeping an eye on the available runway—allows for the implementation of effective strategies and the ability to adapt the business to the company's needs.
