Services

Own product
Proof in production: DaelSoft doesn’t only advise — we also ship and operate software.
Arquealos
Real-time BCRA credit status lookup
Own product in production: integration with the official BCRA registry, live CUIT lookup, and a privacy-first approach (no credit-query history stored). Concrete proof of APIs, official data, and operable software in the market.
Cases
Typical outcomes in real contexts. Names omitted when confidentiality applies.
Logistics company
Legacy PHP stabilized without a full rewrite
A critical system failed under operational peaks. The core was stabilized, priority patches applied, and a staged roadmap defined. Result: fewer incidents and business continuity while modernizing.
SME with multiple reporting areas
One source of truth for decisions
Sales, operations, and finance reported different figures. The model, pipeline, and ownership criteria were unified. Result: a shared number and less time lost assembling spreadsheets.
Operations team
Repetitive work off the daily schedule
Manual tasks consumed hours and introduced errors. Operable flows were automated (n8n and clear criteria). Result: lower operating cost and less “runs on someone’s machine” dependency.
