How will Upside integrate new solutions with our existing systems and tech stack?

How will Upside integrate new solutions with our existing systems and tech stack?

We prioritize integration from day one. Our engineers will audit your current systems (ERP, CRM, inventory management, etc.) and design interfaces or middleware as needed. We often use APIs or custom connectors to ensure the e-commerce platform seamlessly exchanges data with your legacy applications. Upside’s experience with systems like SAP, Salesforce, and custom databases means we can integrate without disrupting your operations. Expect a solution that fits into your environment with minimal friction.

Can you handle scaling our platform for high traffic and peak loads (e.g., Black Friday)?

Can you handle scaling our platform for high traffic and peak loads (e.g., Black Friday)?

Yes. Scalability and reliability are core to our approach. We design architectures with auto-scaling cloud infrastructure, load balancing, and optimized databases to handle traffic spikes. For example, we’ve built e-commerce systems that processed thousands of orders per minute during flash sales without downtime. We also do capacity planning and rigorous load testing as part of our delivery, so you’ll be confident that your platform can grow and handle peak demand smoothly.

What is Upside’s experience with e-commerce security and compliance (PCI DSS, GDPR)?

What is Upside’s experience with e-commerce security and compliance (PCI DSS, GDPR)?

Security is non-negotiable for us. We follow best practices for application security (code reviews, penetration testing, encryption of sensitive data) and ensure compliance with standards. Upside has implemented PCI-DSS compliant payment integrations and is well-versed in GDPR requirements for user data privacy in e-commerce. In short, we build platforms that protect customer data and transactional information with enterprise-grade security. We can also assist with audits and documentation to give your stakeholders peace of mind.

Which e-commerce platforms or technologies do you specialize in? Will you work with our preferred stack?

Which e-commerce platforms or technologies do you specialize in? Will you work with our preferred stack?

We are technology-agnostic in the sense that we choose the best tool for the job – and we can work with the stack you prefer. Our team has deep expertise in popular e-commerce frameworks like Shopify Plus, Shopware, Magento, Spree/Solidus, Saleor, and Medusa, as well as custom builds in Ruby, Python (Django), and Node/React. If you have an existing platform, we can optimize or extend it. If you’re looking to migrate, we’ll recommend a stack that fits your business and scalability needs. The bottom line: we speak your language, whether it’s a SaaS platform or a headless custom architecture.

How does Upside ensure a smooth replatforming or project delivery (what is your process)?

How does Upside ensure a smooth replatforming or project delivery (what is your process)?

We follow a proven development process with a focus on risk mitigation. For a replatforming, for example, we start with a thorough discovery and planning phase (including stakeholder workshops and architecture audits). We then use an agile approach to build the new platform iteratively, all while setting up continuous integration/testing to catch issues early. Before switching over, we run the new system in parallel (if possible) or perform a staged rollout to ensure everything works in real conditions. Our team also prepares extensive fallback and data migration plans. Finally, we don’t consider it “done” at launch – we monitor the platform closely and have engineers on standby to quickly address any post-launch issues. This disciplined approach ensures minimal downtime and a seamless cut-over for your team and customers.

What kind of results have you delivered for e-commerce clients (any metrics)?

What kind of results have you delivered for e-commerce clients (any metrics)?

We’re very results-driven. To give a couple of examples: we helped SimOptions increase their conversion rate by 17% after a complete UX overhaul and performance tuning. For another client, we enabled international expansion to new markets within a year by refactoring their platform for multi-language and multi-currency support. And for a retail brand, we implemented a new mobile ordering channel that boosted customer engagement and internal productivity. We’d be happy to discuss more relevant case studies and the KPIs we achieved in a call – we measure success in terms of both technical performance and business outcomes.
