Why businesses outgrow spreadsheets and off-the-shelf tools
Fragmented data and systems
Inventory, orders, and reports spread across disconnected tools. Reconciling everything costs hours and creates errors
Critical knowledge outside the system
Key data lives in someone's head, not in a platform. One person leaving can disrupt operations
Requests falling through the gaps
Inquiries arrive through different channels, get missed, or aren't tracked. No single place to manage client communication
Dependency on third-party platforms
Every order through an external marketplace costs a significant commission — and the customer data stays with them, not with you

Frequently Asked Questions
Off-the-shelf platforms are built for the average use case — not yours. A custom system fits your workflows, integrates with your existing tools, and you own it outright. No monthly fees, no feature limits, no dependency on a vendor's roadmap.
Yes. We integrate with CRM, ERP, accounting, analytics, and payment systems — including HubSpot, Salesforce, Odoo, Stripe, Mollie, Google Workspace, and custom APIs.
Smaller internal tools may take several weeks. CRM, ERP, and B2B platforms with integrations usually take several months. After discovery, we prepare a roadmap with milestones and timeline.
We start with a discovery call to understand your workflows, integrations, and goals. Have documentation or requirements? We'll review them.
Full ownership. No vendor lock-in.
You receive the source code, documentation, and infrastructure access — as defined in the contract.

We build and support web platforms for clients across Europe, including the Netherlands, Germany, Belgium, and the wider EU — as well as the UK and North America. All communication happens in English, over video calls and shared project tools, no on-site presence required. Data hosting and processing can be set up to meet GDPR requirements.
Custom Web Development Services for Growing Businesses in Europe
Sailet is a custom web development company that builds CRM systems, ERP platforms, B2B portals, and business automation software for companies across Europe, including the Netherlands. Instead of adapting your operations to fit an off-the-shelf tool, we design web applications around how your business already works — connecting sales, operations, inventory, and client communication in one platform you fully own.
Our web development process starts with a discovery call, where we map your current workflows, data sources, and integrations. From there, our team designs the system architecture and interface, builds the frontend and backend, connects it to your existing CRM, ERP, accounting, or payment tools — including HubSpot, Salesforce, Odoo, Stripe, and Mollie — and deploys it on infrastructure you control. Every project includes three months of post-launch monitoring and bug fixes at no extra cost.
We work with distributors, logistics companies, manufacturers, non-profits, and B2B service providers who have outgrown spreadsheets, disconnected SaaS subscriptions, or third-party marketplaces that keep customer data outside their business. Typical projects include B2B ordering portals for partners and dealers, custom CRM and ERP systems, internal tools for operations teams, and marketplace or eCommerce platforms with integrated payments and logistics.
Every system we deliver comes with full source code, technical documentation, and infrastructure access — there is no subscription, no vendor lock-in, and no dependency on our team to keep the software running. Scope, budget, and timeline are fixed in the contract before development starts, so what you agree to is what you get.
If your business is ready to replace manual processes and fragmented tools with a system built specifically for how you operate, book a discovery call with our team.
