Getting Q4 right is a year-round job. This covers forecasting sales, inventory planning, cash flow, order timing, pricing, and the overlooked Q5 stretch.

Q4 preparation starts at the beginning of the year, not in September. Stephen Brown walks the finance side: validating the sales and marketing plan, checking it against the calendar, ordering inventory in late spring, and getting lines of credit expanded before you need them. He also makes the case that Q4 is for demand capture rather than demand creation, because acquiring new customers when everyone is bidding gets expensive.

Stephen Brown walks a seven-worksheet budget template built for ecommerce, from channel-level revenue through COGS, fulfillment, merchant fees, and payroll. His method for a first budget is deliberately simple: take last year's numbers and apply a growth uplift. He spends most of the time on revenue, because everything downstream depends on it, and closes on the part most people skip, comparing actuals to budget every month and adjusting.

A business has cash flowing in and out on cycles that a bank balance won't tell you about, which is why budgeting is a control rather than a chore. Stephen Brown covers why to budget, why a spreadsheet beats a third-party tool when you're starting, how to structure the model around your profit and loss, and what to actually do with the variance each month. His recurring point is that the budget is a financial model you keep tweaking.

Stephen Brown and Preston Alder co-own Solé Toscana, bought in 2022 at what Stephen calls the worst possible time to buy an ecommerce business. They burned cash for a year, got profit religion, and built three things: an annual budget, a 12 month cash flow with an inventory purchase plan, and a 13 week tactical forecast. The result was roughly 40% growth in 2024 alongside higher profitability. They cover what each does, who builds which part, and when.
Your sales forecast and inventory plan are key inputs for building your cash flow forecast. Add expected fulfillment costs, merchant fees, advertising, and other operating expenses to see when you may have cash gaps. From there, you can build a working capital strategy to make sure you have enough cash when you need it.

From there, you can see when money is coming in and going out, and develop a working capital strategy around the gaps.
Read: Build the cash flow plan behind your Q4Start with wages: hourly rate times weekly hours times 52 weeks, or annual salary. Add employer payroll taxes, at least 7.65% for Social Security and Medicare plus any state taxes, and the cost of benefits. Divide by 12 to get the monthly figure for your budget.
