Custom Systems

I build custom systems for retail, restaurants, pharmacies, hospitality, and time tracking, plus APIs and integrations. My focus isn't selling you a monthly license—it's delivering a system that fits how your business operates today and that you can keep using without depending on a vendor who raises prices or disappears.

What my custom systems service includes

I work from requirements gathering through source code delivery. If your operation already runs on spreadsheets and WhatsApp, I document that real workflow before proposing a solution, because a system that doesn't reflect your day-to-day ends up abandoned within three months.

• POS and inventory control: sales, stock by location, mixed payment methods (cash, card, Yape, Plin), and cash closing.
• Business management systems: sales, purchasing, inventory, reporting, and differentiated user roles.
• APIs and integrations: connection with SUNAT (Peruvian tax authority), local payment gateways (Culqi, Niubiz, MercadoPago), or existing systems.
• Process automation: elimination of repetitive manual tasks like sales logging, stock updates, or report generation.
• Source code and training: the software is registered under your name, with a transfer session so your team can manage it.

How much a custom system costs in Peru in 2026

Real market ranges in Peru for 2026 place a basic system (registration, listing, simple reports, one role) at S/ 8,000–S/ 20,000. A mid-sized management system (basic CRM, inventory, sales, 3-5 roles) runs S/ 20,000–S/ 55,000. A custom ERP with proprietary modules starts at S/ 40,000 and can exceed S/ 100,000 depending on scope .

My starting rate of $2,150 corresponds to the most basic system: one core module (sales or inventory), one user role, simple reports, database, and source code. It is not the price of a full ERP. Projects with multiple roles, SUNAT integration, or complex business rules require a specific quote.

Costs to consider beyond development

A production system has operating expenses independent of development: hosting or server (from $10/month depending on volume), annual maintenance typically running 15-20% of the initial cost for bug fixes and compatibility, and potential integration costs with SUNAT or payment gateways depending on transaction volume .
