The freelancer who ignored her books — until tax season
Maria, a freelance graphic designer in Lisbon, spent her first two years invoicing clients through a spreadsheet with no structure — just a list of amounts received. When tax season arrived, she couldn't tell her accountant which expenses were deductible, which invoices were still unpaid, or whether she had actually made a profit. Her accountant rebuilt a year of transactions from bank statements alone, a job that took three weeks and cost more than bookkeeping software would have cost for the entire year.
The lesson she took away — and the one interviewers want to hear articulated — is that double-entry bookkeeping isn't bureaucracy for its own sake. It is the only reliable way to answer two questions any business owner eventually needs answered fast: what do I own, and what do I owe?
