Accounting, Treasury & Taxes
Our finance and accounting team has successfully supported more than 300 companies operating in Mexico. We have professionals with fluent English and hold weekly meetings with clients to ensure that the chart of accounts at month-end aligns with the financial reports generated in the client’s ERP system.
Among our main service differentiators is the use of DIMSA’s web-based accounting software (ERP), along with full compliance with generally accepted accounting principles. Our team performs the daily recording of accounts payable transactions and prepares the corresponding weekly report. We also handle the preparation of invoices as agreed with the client and the posting of accounting entries within the same month.
Additionally, we prepare the monthly electronic accounting for the SAT, file state taxes, and manage the calculation and control of fixed asset depreciation. We coordinate the monthly accounting close and, when applicable, submit the monthly statistical report to INEGI.
