3SIT

3SIT develops software and integrates IT systems from its base in Mexico City. Alongside bespoke projects for client companies, it runs its own browser-based product, FiscoClic, which handles tax paperwork under the rules of Mexico's tax authority, the SAT.

What 3SIT offers

• FiscoClic — a cloud platform for issuing electronic invoices, keeping electronic accounts and producing electronic payroll receipts in line with SAT requirements; it runs in a browser on a computer or phone with nothing to install.
• Custom software development — systems built around a client's own processes, for companies in several sectors.
• IT integration — connecting existing systems and technologies so they work together.
• Cloud hosting know-how — the company's blog covers Amazon Web Services topics such as EC2 servers, load balancing and Route 53 DNS.
• Video marketing — promotional videos and video brochures, which the firm lists among its specialities.

Who it works with

FiscoClic is aimed at micro and small businesses and self-employed professionals who must issue tax-compliant invoices and payroll receipts. The bespoke development side serves companies that need software shaped to how they already work.
