Your business numbers, clear.

Before

Selling, stock and invoicing across three tools.

Now

One system with CFDI 4.0 that sells offline.

Multi-tenant admin and point-of-sale system for Mexican SMBs: catalog, inventory, sales and CFDI 4.0 invoicing — working even when the internet drops.

The full case

The problem

A Mexican SMB needs to sell, control inventory and issue CFDI 4.0 invoices, and usually ends up with three tools that don't talk to each other. And a point of sale has a demand the others don't: if the internet drops, the sale can't stop.

What was built

One multi-tenant system with an offline-first point of sale: the sale is recorded on the device and syncs itself when the signal returns. MXN, 16% VAT and CFDI 4.0 stamping through a PAC.

Status

Open to businesses at nuxa.mx: sign-up happens online and plans scale by business size, not by industry.

Built with
