Financial Planning

Overview

Most solopreneurs avoid financial planning until something goes wrong — a surprise tax bill, a month where expenses eat all revenue, or a decision made without understanding the numbers. This playbook gives you a lightweight but rigorous financial system that takes 30 minutes to set up and 15 minutes per month to maintain. No accounting degree required.

Step 1: Set Up Your Financial Reality Baseline

Before planning, know where you actually stand right now.

Gather these numbers (estimate if you don't have exact figures):

Monthly revenue (average of last 3 months if you have history; projected if pre-revenue)

Monthly fixed expenses (rent/co-working, tools/subscriptions, insurance, hosting, internet — things that don't change month to month)

Monthly variable expenses (marketing spend, contractor payments, per-transaction fees, travel — things that fluctuate)

One-time expenses coming up in the next 6 months (equipment, legal, conferences, annual subscriptions)

Personal income need (the minimum you need to pay yourself each month to cover personal living costs)

Write these down. This is your baseline. Everything else in this playbook builds on it.

Step 2: Build Your Monthly Budget

A budget is simply: how much money do you plan to spend in each category, and how much do you plan to bring in?

Budget structure:

MONTHLY BUDGET
==============
REVENUE
  Product/Service Revenue:        $________
  Secondary Revenue Streams:      $________
  TOTAL REVENUE:                  $________
EXPENSES — FIXED
  Hosting & Infrastructure:       $________
  Tools & Software:               $________
  Insurance:                      $________
  Legal / Professional Services:  $________
  Other Fixed:                    $________
  TOTAL FIXED:                    $________
EXPENSES — VARIABLE
  Marketing & Advertising:        $________
  Contractor / Freelancer:        $________
  Payment Processing Fees:        $________
  Travel & Events:                $________
  Education & Learning:           $________
  Other Variable:                 $________
  TOTAL VARIABLE:                 $________
TOTAL EXPENSES:                   $________  (Fixed + Variable)
GROSS PROFIT:                     $________  (Revenue - Expenses)
OWNER SALARY (your pay):          $________
NET PROFIT (retained in business):$________  (Gross Profit - Owner Salary)

Rules:

Marketing budget should be 10-20% of revenue (or a fixed dollar amount if pre-revenue — treat it as an investment with expected ROI).

Owner salary should be set first, then expenses fit around it. If expenses + salary > revenue, something must be cut or revenue must grow.

Always budget a 10-15% buffer for unexpected costs. Unexpected things always happen.

Step 3: Cash Flow Forecasting

Revenue on paper is not cash in your account. Cash flow timing is what actually keeps a business alive.

Monthly cash flow forecast (do this 3 months ahead):

CASH FLOW FORECAST
==================
                        Month 1    Month 2    Month 3
Starting Cash:          $________  $________  $________
+ Revenue In:           $________  $________  $________
Expenses Out:         $________  $________  $________
= Ending Cash:          $________  $________  $________

Cash flow timing rules:

Revenue often comes in AFTER the work is done (invoices have Net-15 or Net-30 terms). Budget for this lag.

Some expenses are lumpy (annual subscriptions, quarterly contractor payments). Spread these into monthly equivalents in your budget so you're not surprised.

Keep a cash reserve of 2-3 months of expenses. This is your runway buffer. Without it, one bad month can threaten the business.

Cash flow danger signals:

Ending cash drops below 1 month of expenses → urgent. Cut spending or accelerate collections immediately.

Revenue is growing but cash is flat → you're spending everything you earn. Examine variable expenses.

Revenue is lumpy (big months, dead months) → smooth it out with recurring revenue models or build a larger cash reserve.

Step 4: Set Financial Targets

Targets give you something to measure against and decisions to make when you're off track.

Set targets at three horizons:

Monthly targets:

Minimum revenue to cover expenses + salary

Marketing spend cap

New customer acquisition count

Quarterly targets:

Revenue growth rate (e.g., 10-15% quarter over quarter)

Profit margin target (aim for 30-50% net margin as a solopreneur)

Cash reserve target (build toward 3 months of expenses)

Annual targets:

Total annual revenue

Total annual profit

Owner salary / total compensation target

Business milestones (launch date, customer count, revenue milestone)

When you miss a target: Don't panic. Analyze why. Was it a bad assumption? An external factor? A controllable mistake? Adjust the plan, not just the target.

Step 5: Track Monthly (The 15-Minute Review)

At the end of every month, spend 15 minutes on this review:

1. Actual vs. Budget: Compare every line in your budget to what actually happened. Where did you overspend? Underspend? 2. Revenue vs. Target: Did you hit your revenue target? If not, why? 3. Cash position: What's your current cash balance? Are you above or below your reserve target? 4. One action: Based on this review, identify ONE financial action for next month. (e.g., "Reduce contractor spend by $500", "Raise prices on new customers", "Collect overdue invoice from Client X")

Tools for tracking: A shared Google Sheet is sufficient for most solopreneurs. Dedicated tools (QuickBooks, FreshBooks, Wave) add value once revenue exceeds $5K/month or you have complex expenses. Wave is free and handles basic bookkeeping well.

Step 6: Tax Planning (Integrated, Not Afterthought)

Tax is an expense like any other. Budget for it monthly — not just once a year in a panic.

Solopreneur tax budget rule: Set aside 25-30% of every revenue payment into a separate "tax savings" account. This covers:

Self-employment tax (Social Security + Medicare)

Federal and state income tax

Quarterly estimated tax payments (due Jan 15, Apr 15, Jun 15, Sep 15 in the US)

If you're outside the US: Tax rules vary enormously by country. The percentage may differ but the principle is the same — set aside a fixed percentage of revenue immediately, before you spend it.

If you haven't been doing this and owe back taxes: Calculate the total owed, divide by the months until the deadline, and set that aside each month. Do not ignore it.

Financial Planning Mistakes to Avoid

Treating revenue as profit. Revenue minus expenses = profit. Many solopreneurs conflate the two.

Not paying yourself a salary. If you don't pay yourself, you don't know if the business is actually profitable for YOU.

Ignoring taxes until April (or your country's equivalent). Tax surprises are the #1 financial crisis for solopreneurs.

Budgeting optimistically. Budget conservatively on revenue (assume less), aggressively on expenses (assume more). Positive surprises are much better than negative ones.

Never revisiting the budget. A budget set in January is stale by March. Update monthly.
