Every startup budget includes the obvious items: equipment, stock, a website, maybe a van. The costs that sink first-year businesses are rarely the obvious ones. They are small, recurring and invisible until the invoice arrives, and they cluster in the months when revenue is still thin.

Deposits and connection costs

Rent is quoted monthly, but landlords usually want a deposit, sometimes a quarter's rent in advance, plus legal fees for the lease review. Utilities want deposits from businesses with no trading history. Insurance may need paying annually upfront. Broadband, card terminals and waste collection all arrive with setup charges before they deliver anything.

Add these to the month-one column, not the annual one. A unit that costs a thousand a month can easily require four thousand before you unlock the door, and none of it appears on the rent quotation you were shown.

Compliance that appears after trading starts

Licences, permits, inspections, fire equipment, signage approval, food safety training, waste contracts, music licensing. Each is modest. Together they can be a month's profit, and several only surface once an inspector or a supplier mentions them.

Before signing anything, ask the local authority and your sector body what a business at your address, doing your activity, is required to hold. Do this in writing so you have a record of what you were told.

The subscription stack

Accounting software, email, file storage, scheduling, design tools, a password manager, a booking system, a review tool. Individually trivial; collectively a fixed cost that persists whether you trade or not. Most owners accumulate these one useful decision at a time, then discover they are paying for four tools that overlap.

Write every subscription into one list with its renewal date and the job it does. Cancel anything that cannot name a specific job. Review quarterly, because trials convert silently.

Payment and platform fees

Card fees, marketplace commissions, payment processor charges, currency conversion, chargeback fees, delivery platform commissions. These are percentages, so they grow with revenue and quietly reduce the margin you thought you had.

Calculate the real cost of taking a payment through each channel you use, then price accordingly. A service priced at a round number with a generous card fee and a platform commission can lose a surprising share of its value before the money reaches your account.

The price on your invoice is not the money you keep. Work out the difference per channel once, and you will never price blind again.

Replacing your own unpaid labour

In the first year you do the bookkeeping, the marketing, the packing and the cleaning, usually at night. That is normal. The cost appears later, when growth requires someone to be paid for work you were doing free, or when a backlog of unrecorded receipts turns into an accountant's bill.

Budget for the first hire or the first outsourced task before you need it. Even a few hours a month of bookkeeping bought early prevents a painful catch-up later.

Contingency, properly sized

A contingency line of five percent is decoration. For a first-year business, hold a cash reserve equal to three months of fixed costs, and treat it as untouchable. Fixed costs are the ones that keep arriving when sales stop: rent, insurance, software, loan repayments.

Then add a separate small fund for the predictable surprises. Equipment breaks. A sign needs replacing. A deposit is withheld. These are not bad luck; they are the normal texture of running something.

First-year cost checklist

  • Deposit, advance rent and lease legal fees listed separately
  • Utility deposits and connection charges priced before opening
  • Licences, inspections and training costs confirmed with the authority
  • Every subscription listed with renewal date and purpose
  • Payment and platform fees calculated per channel as a percentage
  • Accountant or bookkeeper cost included from month one
  • Three months of fixed costs held as a reserve
  • A small repairs fund that nobody is allowed to spend on marketing

None of this requires pessimism, only arithmetic. Build the list once, put real numbers beside each line, and review it at the end of each quarter. The point is not to frighten yourself out of starting. It is to make sure the first surprise is a minor inconvenience rather than a decision about whether you can keep going.
