What we build, connect and run
Six services that cover the whole life of a commerce platform, from first business analysis through integration and launch to long-term operation.
E-commerce development
From Magento and WooCommerce to fully custom platforms, for complex B2B and B2C businesses: multi-brand, multi-country, multi-store, headless or marketplace.
B2B e-commerce
Customer-specific pricing, account hierarchies, approval flows, quotes, credit limits and contract terms. It is the logic that makes a B2B portal work for customers who buy from you regularly.
Read moreE-commerce integrations
ERP, WMS, PIM, CRM, payment, logistics and POS connected to commerce, so products, stock, prices, orders, customers and invoices stay consistent everywhere they appear.
Read moreCommerce modernisation
Replace an ageing platform without stopping trade: staged migration, frontend modernisation and progressive replacement of the parts that hold you back.
Read moreSubscription commerce
Contracts, plans, billing cycles, usage and upgrades. A self-service portal handles routine requests before they reach your call centre.
Read moreAI & agentic commerce
APIs, MCP servers and controlled tool interfaces that let AI assistants and agents act inside your business rules, not around them.

We solve the commerce problems that don’t fit a standard template
Customer-specific pricing
Contract prices, volume tiers, customer groups and currency rules resolved per account.
Account hierarchies
Parent companies, subsidiaries, cost centres and buyers with distinct permissions.
Complex catalogues
Technical attributes, compatibility rules, variants and hundreds of thousands of SKUs.
Multi-brand & multi-store
A shared product and inventory core, with separate brands, domains and commercial rules.
Multi-country
Tax, language, currency, legal entity and fulfilment differences by market.
Subscriptions & recurring billing
Plans, contracts, renewals, proration, metered usage and dunning.
Marketplaces
Multiple sellers, commission models, split payouts and seller onboarding.
Omnichannel
Web, mobile, stores, POS and customer service sharing the same products, customers, orders and stock.
Custom commerce logic
Business rules that no off-the-shelf platform will ever ship out of the box.

Commerce is only as good as what it connects to
Most of the hard work in enterprise commerce is not the storefront. It is keeping products, prices, stock, customers, orders, invoices and fulfilment consistent across every system that touches them.
- ERP
- SAP, Microsoft Dynamics, custom enterprise systems
- WMS
- Stock, reservations, picking, shipment status
- PIM
- Product content, attributes, media, translations
- CRM
- Accounts, contacts, consent, service history
- Payments
- Card, invoice, SEPA, instalments, B2B terms
- Logistics
- Carriers, labels, tracking, returns
- POS
- In-store sales, click-and-collect, shared stock
- Marketplaces
- Listings, order intake, fulfilment sync

From first analysis to long-term operation
Business analysis
Most platforms are built for launch day and outgrown soon after. In workshops with your commercial, operations and IT people, we map what you run today and where the business is heading, and design for both.
You getA written picture of today and tomorrow, with the problems ranked by business impact.
Architecture & roadmap
We propose the target architecture, integration contracts and a phased plan that leaves room for what comes later. Phase one is scoped to deliver something usable, not months of invisible groundwork.
You getA phase-one scope and estimate, agreed before any build starts.
Build & integrate
Integrations are built alongside features, not bolted on at the end, and go-live is rehearsed before it happens for real.
You getWorking software with your own products and prices from the first weeks, shown in regular demos. No mock-ups.
Operate & evolve
After launch, the work shifts from building to keeping pace with the business. Most of our client relationships are measured in years, not project phases.
You getMonitoring, patching and a roadmap we keep together as markets, channels and pricing change.
How we deliver — not what we sell
We are platform-agnostic by conviction rather than by slogan. The architecture follows the business case — catalogue complexity, integration load, traffic profile and the team who will run it afterwards.
On the commerce layer that means we are equally comfortable building on Medusa or WooCommerce, working within Adobe Commerce and Magento, or building a bespoke commerce core where the business logic genuinely warrants it.
The storefronts and portals in front of that layer are typically built in Next.js or React, and we maintain working depth in Vue.js and Angular where a client team already lives there.
Behind it we work across Node.js, .NET and Java, exposing GraphQL and REST APIs and connecting systems through event-driven integration rather than point-to-point scripts.
Common questions
What kind of e-commerce company are you?
We are an enterprise e-commerce solution provider and software engineering company. We design, build, integrate and operate commerce platforms — B2B, B2C, subscription, multi-brand, marketplace and omnichannel — rather than reselling a single product.
Do you only work with one platform?
No. We work with Medusa, WooCommerce, Adobe Commerce / Magento and fully custom commerce platforms. The platform choice follows the business case: catalogue complexity, pricing logic, integration depth and how much of the domain is genuinely unique to you.
Can you integrate our webshop with SAP or Dynamics?
Yes. ERP integration is one of our core services — products, prices, customers, orders, stock, invoices and fulfilment status, using APIs, events, middleware or dedicated integration services depending on the landscape.
Can you take over an existing platform?
Yes. We regularly take over systems built by others: an audit of the codebase, architecture and integrations first, then a stabilisation phase, then a roadmap. We will tell you honestly if the right answer is to rebuild rather than rescue.
Where are you based and who do you work with?
Uptime OÜ has offices in Estonia, Denmark, Norway, Poland, Switzerland and Spain, and serves enterprises across Scandinavia, the Baltics, Central Europe and the US. We have been building software since 1992 and are ISO 9001:2015 certified.
