Custom quote
No off-the-shelf rates. We hear your need, define the modules and deliver a fixed-price + fixed-deadline quote in 3 working days. The call is free and no-commitment.
Whatever the scope, the following is delivered as standard โ at no extra cost.
Bring these โ in 60 minutes we produce an accurate quote.
We work fixed-price + fixed-deadline. The delivery date is in the contract; if we are late, we pay a 3% weekly penalty (max 20%). We pull this off because we lock scope strictly from the start, avoid scope creep and use AI-assisted code. 23 of our last 24 projects were delivered on time or early (references shared on the call).
**The code is 100% yours.** The GitHub repo is handed over for free. You can continue with any other company or hire in-house developers. Vendor lock-in is not our model โ we retain clients with quality, not contracts.
Quite the opposite. Our senior developer with Cursor + Claude/GPT-4 ships ~40% faster and with 25% fewer bugs than a solo developer (our own measurement). AI writes code, but architecture, code review and tests are done by our 12-year team. Result: same quality, faster, cheaper.
We specialise in SII (Suministro Inmediato de Informaciรณn) โ all issued/received invoices are sent to AEAT within 4 calendar days via signed XML WebService. We implement Verifactu per RD 1007/2023; each invoice carries QR code + chained hash + tamper-proof fingerprint. For clients in the Basque Country, we integrate TicketBAI (Bizkaia/Gipuzkoa/Araba) with BatuZ XML. Forms 303/390/347 generated automatically.
Supported out of the box. The ERP detects the billing province and applies the correct tax regime: VAT 21%/10%/4% peninsular, IGIC 7%/3%/0% in Canary Islands (with Form 420 submission), IPSI in Ceuta and Melilla. Multi-rate within a single invoice when there are mixed lines. Compatible with REDEME and cash-basis regimes.
**Marketplaces:** Amazon ES, El Corte Inglรฉs, PcComponentes, Carrefour, Worten, AliExpress ES, Fnac ES, MediaMarkt ES, Miravia, Privalia, Amazon EU/US, eBay, Bol.com, Allegro. **ERP/Accounting:** SAP Business One, Sage 50/200, Holded, A3 ASESOR, ContaSimple, FacturaDirecta, Quipu, Odoo. **Fiscal:** SII AEAT, Verifactu, TicketBAI. **Payments:** Stripe ES, Bizum, Redsys, Adyen, PayPal, BBVA/Santander virtual POS. **Shipping:** SEUR, Correos, Nacex, MRW, Tipsa, GLS Spain, DHL Spain.

Clarify cost, setup, local fit and operations for custom software development in Spain with ZunaPro.
Companies searching for custom software development in Spain usually compare more than the service name. They look for cost, timeline, a reliable team, local fit and the speed at which the project can become usable.
The page should answer technical and commercial questions together. A visitor needs to understand what will be done, in which order and what will be delivered.
ZunaPro brings workflow analysis, integrations, admin panels, reporting, automation, security and maintainable delivery into one plan. The work does not stay as a design or setup task; it becomes an operating structure the team can actually use.
In Spain, language, payment habits, documentation expectations, delivery or support models can directly influence the result. Discussing these points early reduces rework.
In Spain local Bizum/Visa acceptance, IVA-clear pricing and a Spanish phone line raise conversion.
Before requesting a quote or starting the project, these points should be clear.
| Topic | What It Clarifies | What ZunaPro Does |
|---|---|---|
| Process Analysis | Clarifies expectations, data and responsibility for Process Analysis. | Connects Process Analysis to proposal, setup and ongoing management. |
| Integrations | Clarifies expectations, data and responsibility for Integrations. | Connects Integrations to proposal, setup and ongoing management. |
| Panel And Reporting | Clarifies expectations, data and responsibility for Panel And Reporting. | Connects Panel And Reporting to proposal, setup and ongoing management. |
| Security And Maintenance | Clarifies expectations, data and responsibility for Security And Maintenance. | Connects Security And Maintenance to proposal, setup and ongoing management. |
Process Analysis sets the plan for how custom software development should be delivered in Spain. Scope, timeline and responsibility are written down at this stage so revisions stay rare. Once the plan is locked each team sees its own boundary and small details that look minor at first are still included in the proposal.
When the Process Analysis plan moves to the field, internal roles, approval chains and reporting cadence are defined too. Progress is measured at fixed checkpoints instead of constant meetings, and decisions follow a process rather than a single person.
In practice, Process Analysis should run as a short loop that includes team reviews, customer feedback and real data from the field. At the end of each loop the owner, timeline and expected output of the next step are written down so progress depends on a system, not on a single person.
ZunaPro turns custom software development into a measurable and durable software system aligned with real business workflows by managing scope, technical setup, content structure, tracking and improvement together.
During Integrations, the buyer needs to see which step happens in which order and what is delivered. Local language, payment and compliance details for Spain are discussed here. A transparent process shortens revision cycles, reduces knowledge loss between teams and keeps the delivery calendar reliable.
During Integrations, real user scenarios from the Spain market are tested. Whether the local customer prefers phone, message or a form, and where they hesitate during payment, becomes visible at this stage.
A small but critical detail in Integrations is the content approval chain. Every sentence going live in Spain should be reviewed once more by a local reader; this protects brand tone, legal fit and conversion potential at the same time.
Looking only at the starting price can be misleading. Maintenance, integrations, number of languages, reporting and security requirements shape the real value.
Panel And Reporting is the area that creates the gap between a quote and the real cost. For brands researching Custom Software Development, scope width, content production and integrations shape the total budget. When cost lines are listed individually, comparing offers becomes easier and ROI can be measured from the start.
To read the Panel And Reporting cost line correctly, one-time and monthly figures must sit on separate rows. As scale grows in Spain, integrations, content updates and reporting drive most of the recurring spend.
The Panel And Reporting cost line requires the recurring and variable parts to be visible in writing. Growth decisions like a seasonal campaign, an extra language or a new product category should already be marked on the budget.
A strong service page clearly explains what the buyer gets, what stages they pass through and which workload is removed from their team.
Security And Maintenance keeps living after launch. To keep selling in Spain, maintenance, reporting and content updates must be planned from day one. Without a clear post-launch plan a project erodes within months; a steady support routine keeps brand value intact.
The Security And Maintenance block must turn into a loop of analysis, content refresh, campaign work and technical maintenance. As traffic grows in Spain, every part of this loop needs a clear owner.
The Security And Maintenance block must be fed continuously with customer questions, support tickets and performance data. As live traffic grows in Spain, the behaviour patterns that emerge are the most valuable input for setting the priorities of the next release.
Companies searching for custom software development in Spain usually compare more than the service name. They look for cost, timeline, a reliable team, local fit and the speed at which the project can become usable.
Every project is different, yet custom software development work in Spain usually follows a similar order. The steps below summarise the practical path from the first call to going live and clarify what to look for when reading a proposal.
Many companies make a custom software development decision based only on the starting price. Maintenance cost, local fit and missing reporting often force the project to be rebuilt months later.
When planning custom software development for Spain, local language, payment habits and official procedures should be discussed early. Customer trust is built when contact, invoicing, delivery and support stay consistent.
Spain requires attention to the Madrid-Barcelona axis, access to Portugal and seasonal demand swings.
In Spain, language, payment habits, documentation expectations, delivery or support models can directly influence the result. Discussing these points early reduces rework.
In Spain local Bizum/Visa acceptance, IVA-clear pricing and a Spanish phone line raise conversion.
The three scenarios below show how custom software development positions itself at different scales in the Spain market. The goal is for each business to spot the profile closest to its own situation and to ask the right questions from the start.
A custom software development proposal for Spain should show its components clearly. Itemised quotes prevent later surprises and make comparison between providers possible.
The value of Custom Software Development comes not from launch day but from the steady support that follows. As customer behaviour, campaigns and technical needs in Spain change, the site, system or operation must adapt with them.
With the right structure, teams stop recreating the same information in different places. Sales, operations, support and management can make decisions from one shared source.
It suits companies entering a new market, improving digital sales or organizing an existing operation.
Target market, service scope, languages, payment or contact flows and technical needs should be assessed together.
Scope, integrations, content depth, design needs, official requirements and support model affect pricing.
