At Vitali Alimentos, I optimized the commercial adjustments and credit-note cycle in SAP HANA by 50%. I coordinated validations between Sales, Billing, and Accounting to ensure accurate application against invoices.
At Mayora IP, S.A., I led regional billing and collections across Guatemala, El Salvador, and Honduras. I implemented a portfolio strategy that sustained recovery of up to 90% of global billings and reduced DSO by 25 days.
I also designed automated monthly Power BI dashboards to monitor collection and overdue-portfolio KPIs. By coordinating direct supplier onboarding on SAP and Oracle platforms for VIP accounts, I increased corporate payment receipt efficiency by 65%.
At Tigo Guatemala, I achieved a 95% collection rate on VIP and corporate advertising billings through tailored negotiation and follow-up. My experience also includes receivables analysis, bad-debt risk mitigation, reconciliations, and internal audit support.
