Every lead, quote and invoice — calmly under control.
ZENNO is the all-in-one CRM for installers and small trades in Spain. Capture leads, win the deal, send the quote, and issue a VeriFACTU-compliant invoice — without jumping between Excel, WhatsApp and your accountant.
€29.90/month · flat price · no per-user fees
Built for the way you actually work:
Your business runs on scattered tools — and it shows.
A lead in WhatsApp, a quote in Word, an invoice in Excel, and no idea which deals are actually moving. It works, until it doesn’t.
Leads slip through the cracks
A missed call or a note on paper, and a real job quietly disappears. No pipeline, no follow-up, no visibility.
Quotes and invoices live in Excel
Copy-paste the last file, change the numbers, hope the VAT is right. One template breaks and the whole month is a mess.
VeriFACTU is now the law
Spain’s anti-fraud invoicing rules mean your invoices need certified, chained, traceable records. Excel simply can’t do that.
No clear picture of the money
Who owes you? What did you invoice this quarter? Which clients recur? The answers are buried across five files.
One calm flow, from first contact to paid invoice.
ZENNO follows the way trades actually sell — lead, deal, quote, invoice — so nothing falls between the cracks.
- 01
Capture the lead
Log every prospect with contact, address and source. Assign it to an agent and never lose track of a job again.
- 02
Win the deal
Move deals through your pipeline stages. Record calls, visits, notes and meetings so you always know the next step.
- 03
Send the quote
Turn a deal into a professional presupuesto with your logo, line items and correct IVA — then convert it to an invoice in one click.
- 04
Invoice with VeriFACTU
Issue a compliant factura: chained, hashed, QR-coded and sent to the AEAT automatically. Legal, traceable, done.
A full back office — not just another address book.
ZENNO replaces the pile of spreadsheets and disconnected tools with one system built for Spanish trades.
Leads & deal pipeline
Leads, clients and agents in one place, with a visual pipeline, activities and lead-to-client conversion tracking.
Quotes / Presupuestos
Line-item estimates with per-item IVA, professional branded PDFs, and one-click conversion into an invoice.
Invoices & VeriFACTU
Proforma, definitive and refund invoices, sequential numbering, QR codes and automatic AEAT submission.
Contracts & SEPA
Recurring contracts and subscriptions with SEPA direct-debit batches for maintenance plans and monthly service.
Purchases & IRPF
Register supplier invoices with IVA and IRPF withholding, attach the scan, and keep your expenses tidy.
Bank reconciliation
Import bank movements by CSV and match them to invoices and purchases so you know what’s really been paid.
Financial reports
Cash-flow, revenue vs. expenses, outstanding receivables and recurring revenue — quarter by quarter, at a glance.
Assets & delivery notes
Track equipment you install, rent or own, and issue albaranes tied to the job. Perfect for solar and HVAC.
Be compliant without becoming a tax expert.
VeriFACTU is Spain’s anti-fraud invoicing standard. Every invoice must be recorded, hash-chained and traceable by the AEAT. ZENNO handles all of it silently in the background — you just press "issue".
- Chained & hashed records
- Each invoice is registered and cryptographically chained (SHA-256) to the previous one, exactly as the regulation requires.
- Automatic AEAT submission
- Records are sent to the tax authority over the official SOAP web service — and retried automatically if something fails.
- QR on every invoice
- Each factura carries a verification QR linking to the AEAT, so your clients and inspectors can validate it instantly.
- Your certificate, your control
- Upload your digital certificate once. ZENNO signs and submits; you keep full visibility of every response and incident.
No spreadsheets. No plugins. No last-minute panic.
Tuned to how installers and trades really operate.
Same calm flow, shaped around the details of your work.
From site visit to final invoice
Track every lead and reform job, quote the materials and labour, and invoice progress with the right IVA — all linked to the client and the deal.
Installations, assets and maintenance
Quote the system, register the installed equipment as assets, and bill maintenance on recurring SEPA contracts. Nothing manual.
Jobs now, service revenue later
Win the install, then keep the client with recurring service subscriptions and delivery notes — steady, predictable income.
The easy upgrade from spreadsheets
Everything you already do in Excel — quotes and invoices — plus VeriFACTU compliance and a real view of your clients and money.
A gentle step up — with none of the chaos left behind.
If you invoice in spreadsheets today, ZENNO feels familiar on day one. You keep the simplicity of "make a quote, send an invoice" and gain everything Excel could never give you.
