Bookkeeping notes
What the books look like for Portsmouth businesses like these
Restaurants and food businesses
Daily sales, tips, delivery-app payouts and card fees all land in the bank differently, so each is reconciled on its own. Food and beverage cost is tracked monthly against sales, and sales tax collected is kept apart from revenue.
Shops and retailers
Point-of-sale totals are matched to deposits, inventory purchases are separated from operating costs, and sales tax is tracked by period. A monthly inventory and gross margin check shows which lines actually pay.
General bookkeeping practice, not tax or legal advice.
Beyond the books
Bookkeeping, then a plan for the numbers
Once the books are current, the useful questions change. Can Portsmouth owners afford the next hire, the new truck or the second location, and what will the bank want to see first? That is financial planning, and it only works on accurate records.
Fractional CFO support is a few hours a month of senior financial attention instead of a full-time hire. It sits on top of your monthly books. For tax returns, audits or legal questions we work alongside your CPA or attorney, and we are not a CPA firm.
What that can include
- Preparation for bringing in a partner, selling or an outside review
- A rolling 13-week cash flow forecast, so a slow month is not a surprise
- Loan, line of credit and payoff scenarios
