The hands you're missing.
I'm Lupita. I handle your collections. Magda stamps CFDI and payment receipts at the SAT. Rosa gathers your client paperwork. We work inside your CONTPAQi, quietly, while you focus on what truly needs your judgment.
In 2 weeks your practice collects and invoices on its own. 14-day trial, no card required. Cancel anytime from the dashboard.
Collecting, invoicing and chasing paperwork shouldn't be your day.
If you run a Mexican accounting practice with 10 to 150 monthly retainers, you know the pattern: the first week of every month vanishes chasing collections, reminding clients of deadlines, resending CFDI. Your human assistant gets stuck answering the same questions. You postpone the close because admin work never stops.
It's not your fault. It's what happens when one person handles administrative and professional work at the same time. The hands don't reach.
Cumplida is the hands you're missing. Three digital employees — Lupita, Magda and Rosa — who take over collecting retainers, stamping at the SAT, and gathering client paperwork. They work inside your CONTPAQi. They don't decide for you: they ask you when there's something to decide.
You stay the accountant. They handle the rest.
— Oscar Mizael Nuñez Garcia, founder of Cumplida
We work where you already work.
No system migration. We connect to what you already use — and we keep messaging your clients from your own inbox and WhatsApp.
How each employee works with you.
Three real days, one for each. See who they reach out to, what they decide, and what they report back at close. Every message goes out with client, CFDI and cartera context — no generic scripts.
