How long does it take to build custom software?

A focused MVP can ship in 4 to 8 weeks. A complete first version with admin panel, payments and integrations typically takes 3 to 6 months. Roadmap iterations continue monthly after launch with a smaller maintenance and improvement budget.

What should I send in the first email to a developer?

Business goal, who uses the software, the 3 main user actions, current integrations (CRM, payments, ERP, APIs), expected launch date and any budget reference. References or rough sketches are very welcome. The clearer the brief, the faster you get a precise quote.

How to hire custom software development (2026 guide)

Q: How much does custom software cost in 2026?

A useful MVP usually ranges from $8,000 to $35,000 depending on integrations, auth, payments and infrastructure. Mid-sized internal tools land between $25,000 and $90,000. Production-grade SaaS or marketplaces tend to start at $60,000 and scale to several hundred thousand for multi-tenant features, billing and SLAs.

Q: Fixed price or time and materials?

Use fixed price for well-defined MVPs and milestone-based projects. Use time and materials when scope evolves week to week (typical after the MVP launches). A hybrid approach works well: fixed price for the MVP, monthly retainer for iteration and support.

A practical, founder-friendly playbook to brief, budget and contract a custom software team — without overpaying or losing months in clarification calls. Written by the RoviDev team after shipping internal tools, SaaS products and integrations for clients in Spain, the EU and LATAM.

1. Decide what you are actually buying

"Custom software" can mean four very different things: an internal tool for your team, a customer-facing app, a SaaS product you sell, or an integration that wires existing systems (CRM, ERP, payments, marketplaces). Be explicit on day one — the price, timeline and team profile change radically. A good provider will ask this in the first 10 minutes.

Internal tool: dashboards, automation, custom workflows. Lower risk, fast ROI.
Customer app or website: ecommerce, booking, member areas, mobile. UX and SEO matter.
SaaS product: multi-tenant, billing, auth, roles, audit trail. Bigger upfront effort.
Integration / automation: connect CRM, ERP, payments, AI APIs, webhooks. Often the highest ROI.

2. Brief the developer like a pro

A good first email saves weeks. Send:

Business goal in one sentence (sell more, save hours, launch a product, replace a spreadsheet).
The 3 main actions a user must complete inside the software.
Integrations needed (Stripe, HubSpot, Holded, Shopify, Telegram, OpenAI…).
Reference apps you like (UI or behaviour) and any rough sketches.
Constraints: deadline, budget ballpark, must-have stack (or "no preference").

Want a shortcut? Use our software cost calculator first — it forces those decisions in 2 minutes and produces a number you can validate with any provider.

3. Budget ranges for 2026 (honest)

Real numbers we see in the EU market this year:

MVP (4–8 weeks): $8,000–$35,000 — one core flow, one user role, basic auth.
Internal tool / dashboard: $15,000–$60,000 — auth, roles, exports, integrations.
Customer SaaS v1: $40,000–$120,000 — multi-tenant, billing, admin, audit logs.
Mobile app (React Native / Flutter): $25,000–$90,000 — iOS + Android, push, payments.
AI integration / chatbot / RAG: $6,000–$30,000 — model wrapper, knowledge base, monitoring.
FiveM RP server / gaming backend: $4,000–$25,000 — scripts, anti-cheat, panel.

After launch, expect a monthly retainer of 10–20% of the build cost for fixes, small features, security patches and hosting supervision.

4. Fixed price, time & materials, or hybrid

There is no "best" model — there is a best model for each phase. We recommend:

MVP phase: fixed price, milestone-based. Forces clarity, removes risk.
Post-launch: monthly retainer (time and materials with a cap). Allows fast iteration.
Long maintenance: support SLA with a small minimum and pay-as-you-go for new features.

5. The contract checklist

Before signing, make sure these are written:

Ownership of code and IP transfers to you on payment.
Repository access from day one (you should be able to clone the code).
Hosting and credentials belong to your accounts, not the provider's.
NDA and GDPR / data processing agreement if you handle personal data.
Acceptance criteria per milestone (what "done" looks like).
Warranty period after delivery (30–90 days of free bugfix is standard).
Exit clause: handover, documentation, knowledge transfer if you switch providers.

6. Red flags when hiring

No questions before quoting. A serious developer asks before pricing.
No portfolio or only screenshots — ask for live URLs and a short video walkthrough.
The price is suspiciously low. Cheap up front usually means expensive later.
They want to host on their own servers without giving you root access.
No mention of testing, deployment process, monitoring or backups.
Communication only via chat with no shared board, no weekly demo.

7. Where RoviDev fits

RoviDev is a senior software studio working remotely from Spain. We ship MVPs in 4–8 weeks, run integrations with the most common business tools, and stay on as a monthly partner once the product is live. See the hire map to pick the closest service:
