Ask five vendors to quote for "a website" or "an app" and you will often receive five prices that differ several times over, along with five different delivery dates. That is rarely because some vendors are honest and others are not. More often, each has imagined a different project. Understanding what drives website and app development cost and timeline is the best way to set a realistic budget, brief vendors properly and compare their quotes on equal terms.
This guide explains the factors that matter most for websites, portals, e-commerce stores and mobile apps in Saudi Arabia, and how to write a brief that produces comparable proposals.
What drives website and app development cost
1. Scope and complexity
Scope is the biggest single factor. A five-page corporate site, a member portal with user accounts and workflows, a multi-vendor marketplace and a booking app with real-time availability are entirely different undertakings. The key questions are:
- How many distinct page types, user roles and workflows are there?
- Does the project need user registration, dashboards, search and filtering, notifications or reporting?
- Is there an admin back office, and how sophisticated does it need to be?
- For apps: iOS, Android or both? Native or cross-platform? Is a companion web dashboard required?
Every feature carries design, development, testing and maintenance effort. A clear list of must-have features for the first release, kept separate from the "nice to have later" list, is the most powerful lever you have on both cost and timeline.
2. Integrations
Integrations are where projects most often overrun. Each connection to another system needs analysis, development, testing and coordination with a third party. Common examples in the Kingdom include:
- Payment gateways, including support for mada cards and popular digital wallets, together with the merchant onboarding steps that come with them.
- Government platforms, such as identity verification through the National Single Sign-On (Nafath) or e-invoicing requirements from the Zakat, Tax and Customs Authority (ZATCA), which often involve approval processes and specific technical requirements.
- ERP, accounting, CRM or inventory systems already in use within the organisation.
- Shipping, SMS and email service providers.
Integration timelines depend partly on the third party, not only on the developer, so build that into your plan.
3. Bilingual Arabic and English with proper RTL
A genuinely bilingual site is not an English site with translated text. Proper right-to-left (RTL) support means mirrored layouts, navigation and icons; Arabic typography that stays legible at every size; correct handling of mixed Arabic and English text, numbers and dates, including Hijri dates where relevant; and separate search metadata and URLs for each language. Done well, it adds design and testing effort across every screen. Done poorly, it undermines credibility with Arabic-speaking users. Make it a requirement from day one rather than an afterthought.
4. Content readiness
Content is among the most underestimated causes of delay. Text in both languages, product data, photography, video, legal pages and policies all need to be written, translated, approved and loaded. If the content is not ready, the launch slips however quickly development is completed. Decide early who writes, who translates and who approves, and whether you need the vendor's help.
5. Design depth
Design ranges from adapting a quality template to a fully bespoke interface with original illustration, motion and a component library. Bespoke work typically involves research, wireframes, prototypes and several review rounds. Every round of feedback adds time, so consolidate comments and nominate a single decision-maker.
6. Content management system (CMS)
How will your team update the site after launch? An off-the-shelf CMS, a headless CMS and a custom admin panel each suit different needs. The more tailored the editing experience, from approval workflows and granular permissions to linking Arabic and English versions of the same content, the more it costs to build.
7. Hosting, launch and maintenance after go-live
Launch is the beginning, not the end. Budget for:
- Hosting suited to your traffic and data requirements.
- Domains and SSL certificates.
- Security updates for the CMS, frameworks and plugins.
- App store updates as Apple and Google release new operating system versions and policies.
- Bug fixes, minor enhancements and backups.
Agreeing a maintenance arrangement at the outset avoids unwelcome surprises later.
What drives the timeline
Timelines are shaped by the same factors, plus a few of their own:
- Decision speed on your side: approvals, feedback rounds and sign-offs.
- Content delivery, as described above.
- Third-party dependencies: payment gateway activation, government integration approvals and app store review.
- Testing time across devices, browsers, both languages and real-world scenarios.
A realistic timeline includes your own organisation's tasks. Most delays happen while the vendor is waiting for content, decisions or third-party approvals.
How to brief vendors so quotes are comparable
A good brief does for a web or app project what a good RFP does for any IT procurement. It should cover:
- Background and objectives: who you are, what the project should achieve and how success will be measured.
- Target users: who will use it, in which languages and on which devices.
- Feature list: prioritised into must-have, should-have and later phases.
- Integrations: every system the project must connect to, with whatever documentation you have.
- Content: what exists, what needs creating and who is responsible for it.
- Design expectations: brand guidelines, examples you like and the level of customisation you expect.
- Technical requirements: hosting preferences, data residency considerations, security and accessibility.
- Post-launch needs: support hours, maintenance scope and response times.
- Timeline and constraints: any fixed dates tied to a campaign, season or event.
Then ask every vendor to price in the same structure, with design, development, integrations, content services, testing, project management, hosting and annual maintenance as separate lines, and with assumptions and exclusions listed. Only then can you compare like with like.
The bottom line
The cost and timeline of a website, portal, e-commerce store or app are driven by scope, integrations, bilingual quality, content readiness, design depth, the CMS and the commitment to maintenance after launch. Clarify these before you approach the market, and the quotes you receive will be closer together, more realistic and far easier to compare.
