ByteWave

ERP and CRM systems

ByteWave builds custom ERP and CRM systems for medium-sized companies and corporations. Sales, warehouse, logistics, HR and customer relationship management - in one integrated system. MVP in 2-4 months, full platform in 6-12 months. Instead of fitting your company into off-the-shelf SaaS, we build a system around your real processes.

Frequently asked questions

Questions? We have answers

Off-the-shelf solutions (Salesforce, SAP, HubSpot) force you to fit company processes into the software. A custom system is the opposite - built around organization's real processes. No per-user licenses, no functional limits, no vendor lock-in. In the long run cheaper, especially above 50 users.

MVP system (1-2 modules, basic integrations) starts from 9,000 EUR. Full system with integrations and data migration is 22,000-65,000 EUR depending on scale. Range quote after Discovery (1-2 meetings, free). Milestone-based payment.

MVP with basic modules takes 2-4 months. Full system with integrations, data migration and team training is 6-12 months. We work iteratively - working module delivered every 2-4 weeks, not one big release at the end.

Yes. We integrate with any system that has an API: Sage, Xero, QuickBooks, NetSuite, local accounting platforms. REST, SOAP, webhooks, CSV/XML files, EDI. If there's no API - we build adapters on file imports or intermediate databases.

Migration is a standard project stage. We analyze the structure of old data, map to the new model, clean duplicates. Parallel migration mode - old and new systems run side by side until full transition, with no business downtime.
