Why not buy off-the-shelf ERP/CRM?
Often you should. We say so when a product fits. Custom wins when your process is the product — and templates fight you every quarter.
Node.js or .NET?
Node.js when JavaScript teams and API-heavy products dominate; .NET when Windows estates, enterprise integrations or existing C# skills do. PostgreSQL is our default data layer either way.
Will we be locked into ZACSOL?
No. Code, infra and docs are yours. Handover is a phase, not a surprise.
