Custom-built software
for real business problems
Since 2000, Pentagrama has designed, built, and maintained bespoke technology solutions for companies that cannot afford mediocrity. Whether you need a high-conversion e-commerce platform, a purpose-built internal system, or seamless integration across your technology stack, we deliver it with precision and long-term accountability.
Talk to our teamE-commerce & Digital Commerce Platforms
Selling online is far more than putting a product catalogue on a webpage. Pentagrama builds fully tailored e-commerce environments — architected around your catalogue structure, fulfilment workflow, pricing logic, and customer journey. We work with established platforms where they fit, and build entirely from scratch when your requirements demand it.
Every storefront we deliver is optimised for conversion, indexed for search, connected to your payment infrastructure, and ready to scale. We integrate with the leading payment gateways operating in Brazil and abroad, synchronise orders with your ERP in real time, and link your store into the major marketplaces so you reach customers wherever they browse.
Reduced cart abandonment, faster order processing, and a unified view of inventory and revenue — all without your team managing brittle manual workarounds between disconnected tools.
Custom Storefront Development
Bespoke front-end experiences — designed to your brand identity, built for performance, and tested across devices. No off-the-shelf themes applied with a palette swap.
Payment Gateway Integration
Native integration with PagSeguro, Mercado Pago, Cielo, Rede, PayPal, and PIX infrastructure. Multi-currency support and instalment logic configured to your commercial rules.
Marketplace Connectivity
Listings management, order routing, and stock synchronisation across Mercado Livre, Amazon, Shopee, Magazine Luiza, and other major marketplaces — all from a single backend.
ERP & Back-office Synchronisation
Real-time order, stock, and pricing data exchanged between your storefront and ERP systems — Totvs, SAP, Bling, Tiny, and others — eliminating double-entry and stock discrepancies.
B2B Commerce Portals
Dedicated wholesale and B2B platforms with customer-specific pricing tables, order approval workflows, minimum quantity rules, and multi-branch account management.
Analytics & Conversion Tracking
Instrumentation of Google Analytics 4, Tag Manager, and custom dashboards so your commercial team can act on real data — funnel drop-offs, best-selling SKUs, and campaign attribution.
Software Factory — Custom Development & Legacy Modernisation
Off-the-shelf software is built for the average company. Pentagrama builds for yours. Our Software Factory discipline covers the complete development lifecycle — from discovery and architecture through delivery, quality assurance, and long-term evolution — operating as an embedded technology partner, not a vendor that disappears after go-live.
We also take on the unglamorous but business-critical work of maintaining and modernising legacy systems: replacing fragile code that no longer has internal knowledge holders, migrating data safely, and incrementally refactoring ageing platforms so they can accept new integrations without collapse.
Technology assets that grow with your company, not against it — with documented codebases, predictable maintenance costs, and a team that genuinely understands your domain.
Bespoke Application Development
Web applications, management systems, internal portals, and operational tools built from the ground up — with architecture decisions made for your specific load, workflow, and data model.
Mobile Application Development
Native and cross-platform mobile apps for iOS and Android — whether a customer-facing app or an internal field-operations tool — designed for the constraints of real-world usage.
Legacy System Maintenance & Support
Ongoing maintenance contracts covering bug fixes, dependency updates, security patches, and feature additions for systems built by previous teams or acquired through M&A activity.
Platform Migration & Modernisation
Safe migration from outdated stacks — Delphi, classic ASP, PHP 5, Access databases — to modern, maintainable architectures, with zero-downtime cutover strategies and full data integrity validation.
Quality Assurance & Testing
Structured testing protocols including automated regression suites, load testing, user-acceptance testing coordination, and pre-release security reviews — so defects don't reach production.
Agile Delivery & Technical Documentation
Sprint-based delivery with defined ceremonies, transparent progress reporting, and comprehensive documentation — so your team always has visibility and never becomes dependent on ours.
Systems Integration & Process Automation
Most companies don't suffer from a lack of software — they suffer from software that doesn't talk to each other. Sales data lives in a CRM that doesn't sync with the ERP. Orders from the e-commerce platform have to be keyed manually into the fulfilment system. Finance reconciles spreadsheets because the accounting tool and the bank feed don't connect.
Pentagrama maps your technology landscape, designs robust integration architecture, and builds the connectors, middleware, and APIs that make your systems behave as one coherent platform. We work with REST and SOAP APIs, EDI formats, webhooks, message queues, and custom FTP-based file exchanges — whatever the existing systems require.
Fewer manual steps, fewer transcription errors, and operational teams freed from data-entry tasks — redirected towards work that actually requires human judgment.
API Design & Development
RESTful and GraphQL APIs built to open standard specifications — versioned, documented, secured with OAuth2, and designed for the consumption patterns of your integration partners and front-end applications.
ERP & CRM Integration
Bidirectional data exchange with Totvs Protheus, SAP Business One, Salesforce, HubSpot, Bling, Tiny ERP, and other platforms — covering customers, orders, inventory, invoicing, and financial reconciliation.
Workflow & Process Automation
Identifying and eliminating repetitive manual steps — order status updates, invoice generation, shipment notifications, approval chains — through event-driven automation tied to your existing systems.
Logistics & Carrier Connectivity
Integration with Correios, Jadlog, Total Express, and private carrier APIs for automatic quoting, label generation, tracking events, and proof-of-delivery confirmation — surfaced directly in your order management interface.
EDI & Legacy Protocol Handling
Connectivity to systems that pre-date modern APIs — SFTP file exchanges, fixed-width flat files, XML over FTP, and EDI standards — bridged into your current environment without replatforming the source system.
Integration Monitoring & Alerting
Continuous monitoring of all integration points with automated alerting on failures, payload anomalies, and latency thresholds — plus a retry and dead-letter queue mechanism so no transaction is silently lost.
Platforms & technologies we connect
We work with the tools you already have — not the ones a vendor wants to sell you. Our team integrates with ERPs, marketplaces, carriers, payment processors, and communication platforms across the Brazilian and international markets.
From first conversation to long-term partnership
We follow a structured but pragmatic process — disciplined enough to deliver predictably, flexible enough to adapt when your business requirements evolve mid-project.
-
Discovery
We map your processes, constraints, integrations, and success criteria — asking uncomfortable questions before writing a line of code.
-
Architecture
Technology choices, data models, integration patterns, and infrastructure are defined — documented and agreed before development begins.
-
Delivery
Agile sprints with visible progress, regular demos, and clear escalation paths when scope or priorities shift.
-
Launch
Coordinated go-live with rollback plans, hypercare support, and performance benchmarking against the original specification.
-
Evolution
Ongoing development, maintenance, and strategic roadmap support — because the best systems are never truly finished.
