Transportes Guerrero 2015

Evicron built for Transportes Guerrero 2015, a road freight company in the Barcelona area, custom management software that replaced paper delivery-note pads and manual pricing with a single system: delivery notes priced automatically with each client’s rate card, DeCA with QR code, Verifactu-compliant invoicing and a driver app with photo and signature on delivery.

The challenge

The workflow was manual from start to finish. Drivers worked with paper delivery-note pads and wrote up the job on arrival; management priced every delivery note by hand according to each client’s terms, sorted them by client and invoiced each one differently. Hours of repetitive, error-prone admin work — and two legal obligations with deadlines that paper could not meet: Verifactu, in force for companies since January 2026, and the DeCA, mandatory from 5 October 2026.

The solution

We started from the transport platform we had built for SBD go — Next.js, React and TypeScript on Supabase, deployed on Vercel — and adapted it to Transportes Guerrero’s operation, building what did not yet exist:

• Client rate cards: each client has its own rate per service type (route per kilometre, pallet, hour) and its own surcharges — platform, night, holiday, fuel surcharge on the invoice — with manual pricing when a job does not fit. Kilometres are calculated with Google Maps from the company’s base.
• Digital delivery notes created from the panel or the driver’s phone, with reference and supplier per job, PDF with the company’s own numbering and email delivery to the client, individually or in batches.
• DeCA as a living document: created with the job, with a fixed URL and QR code, containing everything Article 6 of Order FOM/2861/2012 requires, and attached to the delivery note; inspectors open it by scanning the QR, no password needed, and it is kept for the legal period.
• Verifactu invoicing: editable draft invoices from delivery notes or from scratch, grouped by client and, when the client requires it, split by supplier even under the same tax ID; invoice records through a certified provider, configurable IBAN and invoice footer, email delivery and payment tracking.
• Driver app (PWA): login by truck code, the day’s jobs, hours per stop, photo and signature on delivery and, for self-employed drivers, a tab with the month’s amounts.
• Configuration in the company’s hands: tax details, series and numbering, VAT, fuel surcharge and texts, without depending on us for every change.

Outcome

Manual pricing of delivery notes is gone: the system applies each client’s rate as the job is registered. The company issues Verifactu-compliant invoices, emails delivery notes and invoices from the system itself and carries the DeCA on every driver’s phone, months ahead of the legal deadline. By reusing the SBD go base, the system was in production in weeks, not months.
