## Summary

The article lists common accounting mistakes among Colombian SMEs (filing returns without paying, mixing personal and business finances, invoicing without supporting documents, misconfiguring accounting tools, omitting filings). It presents Numbi, a Colombian accounting firm that combines artificial intelligence with professional oversight to automate document processing, transaction reconciliation, tax obligation calculation and the detection of inconsistencies. According to the company, the aim is not to replace the accountant's judgement but to reduce operational tasks so that professionals can focus on analysis and strategic support. José Calderón, CEO of Numbi, is quoted on the importance of well-organised accounting for entrepreneurs' decision-making.
