Web application development service

Web Applications

We design and develop modern, functional web applications tailored to your specific business needs. Our approach ensures a seamless user experience and effective results.

A well-built web application is the difference between a process that eats up hours and one your team completes in minutes. At Oasys we build custom platforms that centralize operations, automate repetitive tasks, and scale as your business grows.

What's included

  • Intuitive and customized interfaces.
  • Integration with platforms and APIs.
  • Performance and security optimization.
  • Secure authentication with granular roles and permissions.
  • Admin dashboard with reporting and data export.
  • Technical documentation and training for your internal team.

Ideal for

Companies looking to digitize internal processes, replace shared spreadsheets, launch customer portals, or ship a validated MVP with real users. We work with startups building their first product as well as SMBs looking to modernize legacy systems.

How we work

We define the stack based on the project, working with established market frameworks like React, Vue, Next.js, Flask, Django, and Node.js. Deliveries are weekly, with functional demos from the first week so you see real progress and can adjust direction without surprises. The code stays in a repository you own, with no lock-in.

Frequently Asked Questions

Can I start with an MVP and scale later?

Yes, that's the most recommended path. We define a minimum viable scope to validate with real users, and iterate features from there based on impact. Innovasole de Centroamérica followed this route, and its platform now cuts operating costs by 40%.

What happens to the code once the project ends?

The code and all its dependencies live in a repository you own (GitHub, GitLab, or whichever you prefer). Your company owns the product and can keep evolving it with any developer. There's no forced dependency on us.

Do you include hosting and maintenance?

We can handle deployment on the infrastructure of your choice (AWS, Google Cloud, DigitalOcean, your own VPS) and offer monthly maintenance plans with a response time under 2 hours during business hours. Your own team can also take it over, since we document the entire deployment process.

Android and iOS mobile app development service

Mobile Applications

We develop native and hybrid mobile applications for Android and iOS, designed to deliver smooth, high-performance experiences on any device.

A well-built mobile app is a direct channel to your customers' and employees' pockets: no intermediaries, with push notifications and working even with intermittent connectivity. We help you decide when native makes sense, when hybrid does, and when a PWA is enough — instead of selling you whatever stack suits us best.

What's included?

  • Native (Android/iOS) and hybrid (Flutter, React Native) development.
  • UI/UX design optimized for an exceptional mobile experience.
  • Publishing and maintenance on Google Play Store and App Store.
  • Push notifications, deep linking and integrated analytics.
  • Secure authentication with biometrics, OAuth and enterprise SSO.
  • Integration with internal APIs, payment gateways and cloud services.

Ideal for

Companies with field teams that need mobile tools (logistics, sales, technicians), businesses that want to build customer loyalty with their own app, B2C platforms that need a mobile-first experience, and startups validating their product with real users. Thrivo is an example: a mobile app in production from our portfolio.

How we work

We validate the stack decision with you before writing any code: native when performance and system APIs justify it, hybrid when time-to-market matters most, PWA when there's no need to be in the app stores. Deliveries are weekly with test builds via TestFlight or Internal Testing so your team can try the app on real devices from day one.

Frequently Asked Questions

Native or hybrid? Which one is right for me?

It depends on two factors: do you need deep system APIs (Bluetooth, NFC, advanced camera)? Native. Do you need to launch quickly on Android and iOS with a limited budget? Hybrid (Flutter or React Native). We evaluate this with you in the initial proposal, weighing the pros and cons for your specific case.

Do you handle uploading the app to the stores?

Yes. We manage the Google Play Console and Apple Developer Program accounts, prepare screenshots, ASO-friendly descriptions, privacy policy, and go through the review process. We also renew certificates and handle rejections if Apple/Google requests changes.

Can I update the app without depending on you?

Yes. The code stays in your own repository with CI/CD pipelines configured to generate builds automatically. We document the entire release process and train your team so they can publish updates, or, if you prefer, we can keep doing it for you under a maintenance plan.

Online store and e-commerce development service

E-Commerce & Online Stores

We build complete, sales-optimized online stores. From design to integration with local and international payment gateways, your e-commerce will be ready to generate sales from day one.

An online store isn't a digital catalog — it's a sales engine. We focus on the three factors that most impact conversion: load speed, frictionless checkout, and search engine discoverability. Ghost Tactical Shop, a project from our portfolio, tripled its sales in the first 3 months after launch.

What's included?

  • SEO-optimized stores with built-in search engine positioning.
  • Integration with payment gateways (Visanet, PayPal, Stripe) and logistics.
  • Automated email marketing: abandoned carts, confirmations, and promotions.
  • Integration with shipping platforms (Guatex, Cargo Expreso, DHL, FedEx).
  • Admin panel with inventory, orders, customers, and sales reports.
  • Product schema, reviews, and rich markup for rich results in Google.

Ideal for

Retail businesses looking to open an online channel, private brands selling direct-to-consumer, distributors that need B2B wholesale, and startups moving on from Instagram/marketplaces to have their own domain and stop depending on third-party algorithms.

How we work

We choose the platform based on your expected volume and customization needs: headless with Next.js + Stripe for complex catalogs, Shopify/WooCommerce when time-to-market is critical, or custom development when B2B workflows require it. Weekly deliveries, migration of your existing catalog, and team training to upload products independently.

Frequently asked questions

Which payment gateways work best in Guatemala?

For local GTQ payments we recommend Visanet and Neonet (local cards, 3D Secure). For international USD payments, Stripe and PayPal are the smoothest. We integrate all three in parallel so the customer can choose — this increases conversion without penalizing UX.

How do you manage inventory when I sell across multiple channels?

If you already have an inventory system (ERP, point of sale, spreadsheet), we connect it via API or scheduled sync. If not, the e-commerce store can be the single source of truth. We also integrate with Meta Commerce Manager to sync your catalog on Instagram and Facebook.

Does it include Google search positioning?

It includes technical SEO (indexable structure, Product schema, optimized meta tags, load speed, automatic sitemap). Sustained organic ranking requires content and domain authority over time — we deliver the technical foundation so that work pays off. If you want ongoing content SEO, we have a separate digital marketing service.

API integration service for systems

API Integration

We connect your systems with third-party solutions through API integration, streamlining processes and improving your business's operational efficiency.

The most common symptom: your team copies data between two or three systems several times a day. Every copy is an opportunity for error and hours of work that generate no value. A well-designed integration eliminates that pain, reduces human error, and frees up time for strategic tasks.

What's included?

  • Workflow automation.
  • Connection with leading services like Google, Stripe, or AWS.
  • Adaptation to specific and custom environments.
  • Webhooks and real-time events for bidirectional synchronization.
  • Error handling, automatic retries, and failure alerts.
  • OpenAPI/Swagger documentation plus usage and rate-limit monitoring.

Ideal for

Companies with an ERP or CRM that need to connect to an online store, teams with multiple SaaS tools that don't talk to each other, businesses that want to sync electronic invoicing with SAT or FEL, and platforms that need to securely expose their data to partners or mobile apps.

How we work

We start by mapping the current workflow: who uses which system, what data gets copied where, and what processes break down. We then design the integration, prioritizing the flows with the highest impact and lowest risk. We work with middleware when it makes sense (n8n, Zapier, Make) and build custom integrations in Python/Node.js when the business logic is complex.

Frequently Asked Questions

What happens if the external service's API changes?

We monitor API versions and schedule updates before they are deprecated. For integrations under a maintenance plan, this work is included. For one-time implementation projects, we document the breaking points and train your team to handle them.

Do you integrate with FEL and SAT in Guatemala?

Yes. We integrate with authorized FEL certifiers (G4S, InfileFEL, and others) for automatic invoice issuance from your ERP, POS, or online store. We also connect with the SAT API for NIT lookups and tax validation.

How do you handle credential security?

Credentials live in a secrets manager (AWS Secrets Manager, HashiCorp Vault, or encrypted environment variables depending on the environment), never hardcoded in code or repositories. Periodic rotation, least-privilege principle, and access logging for auditing.

Custom enterprise software service

Enterprise Software

We offer enterprise software solutions that optimize your organization's internal management. Our focus is on developing efficient tools that improve productivity and facilitate decision-making.

Generic enterprise software costs less in licensing but forces you to change your processes to fit its model. A custom system does the opposite: it adapts to how you work today and evolves with your business. Clínica Manantial reduced its administrative workload by 60% with a management system designed specifically for its operation.

What's included?

  • Comprehensive business process management.
  • Automation of repetitive tasks for greater efficiency.
  • Scalability to adapt to business growth.
  • Executive reporting, KPIs and dashboards by department.
  • Granular roles and permissions by user, department, or branch.
  • Integration with electronic invoicing, online banking, corporate email, and existing tools.

Ideal for

Mid-sized companies that have already outgrown what shared spreadsheets can support, organizations with unique processes that don't fit into a generic ERP like SAP or Odoo, and businesses that want to consolidate 3-5 scattered tools into a single system that tells one consistent story.

How we work

We start with an on-the-ground process assessment: we observe how your team works, identify bottlenecks, and prioritize modules by impact. We build the module that solves the most pain first, put it into production with real users, and only then move on to the next one. This avoids year-long projects that end up unused.

Frequently Asked Questions

Custom software or an ERP like Odoo/SAP?

It depends on what percentage of your processes are standard vs. unique. If it's 80/20 standard, a customized ERP makes sense. If you have very particular processes (clinical operations, specialized logistics, a complex B2B model), a custom system gives you more control and lower long-term cost. We evaluate this together in the initial proposal.

How long until it can be used?

We prioritize getting a first module into production within the first few weeks of the project. The complete system is built in iterations — you never wait a year to start using it. Each delivery is fully functional and adds value on its own.

What happens to our current data?

We migrate data from current systems or spreadsheets to the new system. We validate consistency with your team before the cutover. If it makes sense, we keep the old system in read-only mode during the transition for historical queries, while all new work moves to the custom system.

Custom software development service

Custom Software

We develop fully customized software solutions designed to meet your business's specific needs and goals. Every project is unique, and we ensure the tools we create align perfectly with your vision.

Some problems don't have an "off-the-shelf" solution. A logistics operator with particular routes, a clinic with its own protocol, a factory with specific quality variables — each case needs software that understands its rules. We build that software from scratch, aligned with your operational reality.

What's included?

  • Development adaptable to any industry or requirement.
  • Internal process optimization for greater efficiency.
  • Integration with existing systems to improve interoperability.
  • Scalable architecture designed to grow without rewriting code.
  • Technical documentation and user manuals in Spanish.
  • Source code delivered to the client, with no forced dependencies.

Ideal for

Companies with unique processes that don't fit standard solutions, organizations that already tried commercial software and found it lacking, startups with a different idea who want to build their own product from scratch, and businesses that need a competitive edge through technology their competitors don't have.

How we work

We start by understanding your problem before proposing technology: user interviews, process review, and hypothesis validation. We design the minimum viable solution that solves the core pain point, build it with weekly deliveries, test it with real users, and adjust direction based on feedback. In the end you have a product that works, that your team adopts, and that you can keep evolving.

Frequently Asked Questions

How do I know custom software is worth the investment?

We start with a scoped MVP that demonstrates value within a few weeks. If it works and your team adopts it, we scale up. If it doesn't solve the problem as expected, we stop the spending. We don't ask you to bet your entire budget upfront — the commitment is incremental and always based on real results.

What technologies do you use?

The stack is defined by the project, not the other way around. We work with Python (Django, Flask, FastAPI), JavaScript/TypeScript (React, Vue, Next.js, Node), SQL databases (PostgreSQL, MySQL) and NoSQL (MongoDB, Redis), and cloud platforms (AWS, GCP, Azure). We choose whatever best solves your case, not whatever is most convenient for us to sell.

Who owns the code?

Your company. The source code, the documentation, the intellectual property — all of it is in your name. No recurring licenses, no lock-in, no forced dependency on us to evolve the product. You decide whether to keep working with us, manage it internally, or choose another provider later.

AI chatbot and artificial intelligence service for businesses

Chatbots & Artificial Intelligence

We implement intelligent chatbots and AI solutions that automate customer service, optimize internal processes, and enhance your business's user experience.

Modern chatbots are not the rigid decision trees of 5 years ago. With large language models (LLMs) built in, they understand context, hold long conversations, and can query your own data to respond accurately. When well designed, they reduce support ticket volume by 50-70% without sacrificing quality of service.

What's included?

  • Chatbots for websites, WhatsApp Business, and social media.
  • Natural language processing for intelligent, contextual responses.
  • AI-powered workflow and repetitive task automation.
  • Training on your internal documentation (RAG over your own data).
  • Handoff to a human agent when the bot can't resolve a request.
  • Conversation analytics to identify continuous improvements.

Ideal for

Businesses with a high volume of repetitive inquiries (FAQs, order status, scheduling), sales teams that want to qualify leads before human contact, e-commerce businesses looking for conversational shopping assistants, and organizations that manage a lot of internal documentation and want a "chat with your PDFs" experience for their team.

How we work

We first map out the conversations a human currently handles: which questions make up 80% of the volume, which answers are standard, and which cases require judgment. We build the bot against those frequent cases, test it internally with your team, measure accuracy, and expand its scope. We integrate it with your CRM, your knowledge base, and your systems so it responds with up-to-date information, not hallucinations.

Frequently asked questions

Do you use GPT, Claude, or another model?

It depends on the case. For tasks requiring deep reasoning or complex rules, Claude or GPT-4 perform better. For fast responses at high volume, smaller models (GPT-4o-mini, Llama, Gemini Flash) are more cost-efficient. For highly sensitive data, self-hosted open-source models. We choose based on your balance of quality, cost, and privacy.

Can it respond with our internal information without making things up?

Yes. We use a RAG (Retrieval Augmented Generation) architecture: the bot queries your knowledge base, manuals, or systems before responding, and cites the source. If it can't find the information, it escalates to a human instead of making something up. This reduces hallucinations to nearly zero.

How do I integrate the bot with WhatsApp Business?

We connect via the official WhatsApp Business API (through verified providers like Twilio, 360dialog, or Meta directly). The bot can send proactive messages, approved templates, automatic replies, and hand off to human agents when needed. We manage the number verification process and initial setup.

Database and business intelligence service

Databases & Business Intelligence

We design, optimize, and manage robust databases, and create Business Intelligence dashboards that turn your data into strategic decisions.

Many companies have the data but can't use it: it lives in spreadsheets, legacy systems, or reports someone puts together manually on the last day of the month. Our job is to consolidate, model, and expose that information so any leader can see their KPIs in real time, without depending on someone from the data team.

What's included?

  • SQL and NoSQL database design and optimization.
  • Interactive dashboards and real-time executive reports.
  • ETL, data migration, and report automation.
  • Data warehousing and dimensional modeling for historical analysis.
  • Optimization of slow queries and indexes on existing databases.
  • Automated reports by email, Slack, or Teams on a set schedule.

Ideal for

Companies that depend on someone from the team to generate a monthly report in Excel, organizations with data spread across multiple systems that need a consolidated view, growing businesses where database queries have become slow, and teams that want to move from "reactive reporting" to "real-time dashboards."

How we work

We start by identifying the 3-5 most important business decisions made using data and what information they require. Then we design the data model and dashboards for those specific decisions — not generic dashboards that no one looks at. We integrate with your sources (ERP, CRM, POS, spreadsheets, CSV files) and automate updates so the information is always fresh.

Frequently Asked Questions

Is my current database slow — can you optimize it without migrating?

Yes, in most cases. We audit the heaviest queries, review indexes, partitioning, N+1 queries, and engine configuration. Often, specific tweaks improve performance 5-10x without switching databases. If the audit shows that migrating or scaling makes more sense, we'll propose it with evidence.

Which BI tool is right for me?

It depends on budget and use case. Metabase is open-source and performs well for SMBs. Power BI integrates naturally with Microsoft 365. Grafana shines for real-time operational metrics. For unique cases, we build custom dashboards with web technologies (React + charting libraries). We'll evaluate this with you in the proposal.

How do the dashboards get updated with new data?

We automate ingestion with ETL pipelines that run at the frequency you need: real time (CDC, webhooks), every 15 minutes, hourly, or daily. The dashboard always shows the latest version with no manual intervention. We also set up alerts when a KPI falls outside the expected range.

Software maintenance and technical support service

Maintenance & Support

We ensure the continuous and optimal operation of your systems through specialized maintenance and technical support services.

Software that receives no maintenance degrades over time: libraries become outdated, vulnerabilities appear, minor bugs pile up, and one day something breaks with no clear explanation. Our maintenance service prevents that scenario with continuous, preventive work — not just reactive fixes.

What's included?

  • Regular updates and security improvements.
  • Fast incident resolution.
  • Personalized and ongoing technical support.
  • Security patches and monitoring of CVEs relevant to your stack.
  • Bug fixes reported by users or detected through monitoring.
  • Development of minor improvements and features within your contracted monthly hours.

Ideal for

Companies with software in production that need a clear point of responsibility for "what happens if it breaks on a Friday night," internal teams that don't want to dedicate a full-time developer to maintaining a single system, and organizations that prefer predictable fixed costs over per-incident billing.

How we work

We define a monthly plan with dedicated hours, a response SLA, and a clear communication channel (email, WhatsApp, ticketing system). At the start, we audit the software to identify risks (outdated dependencies, known vulnerabilities, latent bugs) and prioritize preventive work. Monthly reports cover what was done, what was detected, and what we recommend going forward.

Frequently Asked Questions

Do you maintain software you didn't develop?

Yes, with a prior audit to understand the code, document the architecture, and assess risks. Sometimes we find serious technical debt that requires initial work before entering the regular monthly plan. We're transparent about the scope before you commit.

What happens if I use up all the hours in a month?

You have three options: (1) contract additional hours at the same rate, (2) prioritize which work to postpone to the following month, (3) upgrade to a larger plan if usage is sustained. Always with notice before generating unforeseen costs — no surprise invoices.

Does it include hosting and monitoring?

Hosting is quoted separately since it depends on your stack and cloud provider. Basic monitoring (uptime, errors, alerts) is included in the plan. Advanced monitoring (APM, distributed tracing, centralized logs) is added as needed with tools like Datadog, Sentry, or an open-source stack.
