What It Is

Sizyy is a Colombian custom financial and accounting software development company, not a general-purpose payment gateway or standard SaaS product that can be activated on a monthly plan. It is positioned around building finance, accounting, and regulatory systems tailored to a company’s own workflows, with a focus on scenarios such as DIAN electronic invoicing, accounting engines, AI automation, cooperatives, microloans, payment reconciliation, and Open Banking integrations.

Core Capabilities and Compliance

Based on the available text, Sizyy’s strengths lie in local regulatory expertise and engineering delivery. It explicitly supports DIAN UBL 2.1, CUFE, XAdES-BES signatures, Muisca pre-validation, electronic payroll, credit/debit notes, and file support, and also mentions SUPERSOLIDARIA, NIIF para PyMEs, and PGCP. For broader Latin America expansion, its architecture can be adapted to Peru’s SUNAT, Chile’s SII, and Mexico’s PAC-SAT. Its technology stack includes Apache Fineract, Spring Boot, React, PostgreSQL RLS, AWS LATAM, and event-driven architecture, making it suitable for building core financial systems and large-scale transaction reconciliation modules.

Payments, Risk Control, and Integrations

One important caveat is that the page does not disclose specific payment methods, such as cards, bank transfers, wallets, or local acquiring networks, nor does it provide transaction fees or settlement timelines. As such, it is better viewed as a provider of payment/financial system development and reconciliation capabilities rather than a replacement for a payment acquirer. On the risk-control side, the text mentions AI detection of IVA anomalies, duplicate records, account cross-checks, abnormal financial risks, as well as bank reconciliation and predictive dashboards, but it does not disclose KYC, AML, anti-fraud, or payment risk-control rules.

Pricing, Pros, and Cons

Pricing is relatively transparent: custom development is around 15 million to 120 million COP, with additional options for SaaS licensing, regulatory consulting, monthly maintenance, and training. Its advantages include deep local compliance expertise, customizability, customer ownership of the code IP, a stated MVP timeline of 6–8 weeks, and ongoing maintenance. The drawbacks are that it is not ready to use out of the box and requires a discovery phase before a quote; information on payment licensing, payment rails, pricing rates, and settlement is also insufficient.

Best Fit and Access from China

Sizyy is best suited for mid-sized companies, PyMEs, cooperatives, microloan providers, Fintech companies, and businesses in Colombia and Latin America that need DIAN compliance. For Chinese companies entering the Colombian market, it can be considered as a local compliance system and finance middleware development partner; if the goal is cross-border acquiring, Stripe, Adyen, dLocal, PayU, or Mercado Pago should be evaluated in parallel. Access from mainland China is not stated in the text and is therefore unknown.
