Spun

Spun is billing and quoting software built for construction and renovation professionals in Spain — plumbers, electricians, builders, painters and small building firms. Unlike generalist accounting tools, it speaks the language of the trade: quotes by chapters, line items and measurements; invoices with sequential numbering, series and per-job VAT and IRPF; projects with payment milestones and margin control; per-project expense tracking; voice-dictated quotes; and expenses sent via WhatsApp (a receipt photo or a voice note). Everything from mobile, nothing to install. Designed to adapt to Spain's Verifactu e-invoicing system, subject to the final regulation. Single plan at 14.90 EUR/month, VAT included, no lock-in. Data hosted in the EU.
