# Custom app or readymade app: what I recommend to clients > Which app option I recommend for your business, with real cost and time numbers. How I deliver both with fixed pricing and full ownership. Canonical: https://sachinsharma.work/compare/custom-app-or-readymade-app/ Last updated: 2026-10-27 ## What is a custom app and what is a readymade app? A custom app is built from scratch for your business. It does exactly what you need and nothing extra. I write the code to match your workflow, branding and rules. A readymade app is pre-built for general business needs. You buy or subscribe to it, like Tally or Zoho. It works out of the box but may not fit perfectly. The core difference is fit versus speed. A custom app fits your process like a tailor-made shirt. A readymade app is like ready-to-wear, faster and cheaper, but may need adjustments. For example, a clinic with a unique patient follow-up system may need a custom app. While a standard retail store can use a readymade billing app. If you are not sure what an API is, see what an API is to understand how custom apps connect to other tools. ![Custom app like tailor-made suit; readymade like off-the-shelf. Compare cost and time.](https://sachinsharma.work/engine/custom-app-or-readymade-app/img1.webp?v=f21f15dc) *Choosing between custom and readymade is like picking between a tailor-made and off-the-shelf suit.* ## When to choose a custom app A custom app makes sense when your business runs on unique processes, needs strong brand identity, or plans to scale fast with full control. These needs justify the higher cost and time. For example, a multi-tenant platform for a family-run conglomerate with five brands. You gain full ownership of the code and data, and can integrate with other tools as you grow. Scalability is a valid reason to build custom, as the app can evolve with your business over time. If you need differentiation in how users experience your service, a custom app lets you shape every detail. If you are building a quick commerce app with unique delivery rules or customer flows, building a quick commerce app may require custom work. When scaling, you can choose between growing an in-house team or working with an outsourced developer like me, with no agency layers. ## When to choose a readymade app A readymade app is the better choice when your business follows a proven model and you need to launch fast, affordably, and with minimal setup. You benefit most if your needs are basic and well-defined, such as using a standard website, booking system, or inventory tool. Speed to market is the main reason when early revenue or quick customer feedback matters more than unique features. For example, a local service provider starting online can use a readymade website to go live in days instead of months. These apps work well when scalability is not a near-term concern. If your business grows beyond the app’s limits, you can switch later. Readymade tools like WordPress or SaaS platforms offer reliable performance without custom development. You can compare frameworks like [Next.js or WordPress](https://sachinsharma.work/compare/nextjs-or-wordpress/) to see which readymade base fits your goals. ![Checklist: budget under ₹2.5 lakh, no unique workflow, need fast launch.](https://sachinsharma.work/engine/custom-app-or-readymade-app/img2.webp?v=e4f3211c) *Most small businesses save time and money with a readymade app.* ## Cost of a custom app in India A custom app in India costs $35,000 to $105,000 for a small business. $60,000 to $180,000 for a mid-complexity app. The final price depends on the number of user roles, integrations like payment or GST, offline use, and how much testing and documentation you need. As an estimate, hidden costs like maintenance, training, and scaling can add 30 to 50 percent more over the first year. For example, a $70,000 app could cost $21,000 to $35,000 extra in the first year, as an estimate based on typical hidden costs. These hidden costs are not always listed in initial quotes, so ask for a full breakdown. You can reduce costs by starting with a smaller feature set or using a fixed price model instead of hourly billing. ## Cost of a readymade app You can start with no code and no large upfront payment. Tools like Jotform offer free app templates you can customise without coding. These are good for simple needs like forms, bookings or content. Some free versions may show the provider’s brand or limit features. Paid plans often start at $15 to $50 per month and rise with added users or features. As an estimate, assuming a mid-tier plan with custom branding and integrations, costs range from $100 to $250 per month. Recurring costs include the subscription, any add-ons and time spent managing it. Free tools work well for testing an idea, but may not scale. You must check if the app meets your data and compliance needs over time. ## Time to build a custom app A custom app takes 2 to 4 months to build for a small business. The average timeline depends on how many features you need and which systems it must connect to, like payment gateways or GST billing. I add a 15 to 20 percent buffer to the schedule because unplanned tasks almost always come up. Such as delayed feedback, scope changes, or integration issues. ## Time to set up a readymade app Setting up a readymade app takes 6 to 12 weeks for a typical single-location SME in India when run by an implementation partner. This includes configuration, user training, and testing. The process starts with signing up and choosing your plan. Then you set up user roles, connect payment or inventory systems, and customise fields and reports to match your workflow. Data migration adds 1 to 2 weeks and usually runs alongside setup. You export data from your old system, clean it, and import it into the new app. Some apps support direct imports from tools like Excel or Tally. Others may need manual entry or a script, which can extend the timeline. SaaS configuration alone, without data migration or deep customisation, can take just 3 to 6 weeks. But this shorter timeline does not cover full business readiness. For a smooth launch, plan for the full 6 to 12 weeks. ## Who owns the code and data in a custom app? Yes, you own the code once the app is built, but only if your contract includes an IP assignment clause. By default, Indian law gives ownership of the code to the developer, not the client. To get full ownership, your contract must clearly state that all intellectual property rights are transferred to you. As a founder fact, every client I work with owns their code and data. Custom app development may offer full ownership of the application. ## Who owns the data in a readymade app? You own your business data in a readymade app only if the agreement says so. Otherwise, ownership stays with the provider or is shared. Always check the data ownership clause in your contract. The provider may access your data for service delivery, but only for technical processing. Some providers store data on shared servers, which can increase risk. The agreement must state that you can export your data at any time in a usable format. ## How to check if a readymade app fits You can check if a readymade app fits by asking three key questions. First, **can you export your data at any time?** This ensures you are not locked in and can switch apps later if needed. Always confirm the export includes all records, not just summaries. Second, **does the app allow API access?** This may let you connect it to other tools if the architecture and commercial terms support it. Third, **can you customise branding?** Look for options to add your logo, set your brand colours. Use your domain name so customers see your brand, not the app provider’s. These checks help you keep control, even on a shared platform. ## Worked example: Clinic management app Worked example: Clinic management app A readymade clinic app setup takes 6 to 12 weeks. Annual licence fees under $250 per month total under ₹2.4 lakh per year. These numbers assume a five-module system (appointments, patient records, billing, inventory, reports) and one integration with a payment gateway. The readymade app price is based on a monthly licence fee under $250 per month, annualised to ₹2.4 lakh. Setup time falls within the 6 to 12 week range for SME implementations. The custom app cost converts $35,000 (the lower end of the small business app range) to ₹42 lakh at ₹1,200 per dollar. Build time is mid-range of the 2 to 4 month average for small business projects. As an estimate, assuming 5 core modules and one live integration, the effort and cost scale accordingly. ![Bar chart: custom app costs more than readymade for clinic management.](https://sachinsharma.work/engine/custom-app-or-readymade-app/img3.webp?v=6fd28375) *A custom clinic app costs more than a readymade one.* ## Legal and tax rules for apps in India The Information Technology Act, 2000 came into force on 17th October 2000. This law sets the rules for electronic records, digital signatures, and online contracts. Under it, any system that issues digital signature certificates must host the infrastructure in India. This means the servers for creating and managing digital signatures cannot be outside the country. However, if you are only buying a readymade app license or subscription, the seller should provide the GST invoice, not you. For custom development, your contract should include GST billing so you can claim credit. The infrastructure for generating, issuing, and managing Digital Signature Certificates must be installed in India. This applies whether you are signing documents, authenticating users, or securing internal workflows. For now, store user data securely and get clear consent before collection. Always consult a legal advisor to check your app’s compliance with current laws, especially for sector-specific rules. ## When this advice is wrong When this advice is wrong Do not follow this advice if your business need is unclear or keeps changing. A custom app needs stable requirements. If you have no time to manage the build, a readymade app with quick setup is safer. You can switch from a readymade app to a custom app later. Most readymade apps let you export your data, so you can rebuild on your own terms when the time comes. But moving from a custom app back to a readymade one is rare and costly. You may have to retrain staff and simplify workflows. This path makes sense only if your growth slows or your app becomes too complex to maintain.

I recommend a readymade app for most small businesses in India when the business follows a proven operating model and launch speed matters. Choose custom development when your workflows are unique, you need product differentiation, or long-term control justifies a purpose-built system. ### What changes if I choose the other option? Choosing a custom app means higher upfront cost than a readymade app. In return, you gain full control over features and branding. Choosing a readymade app cuts initial cost and speeds launch, but limits how much you can change. ### Can you migrate me from a readymade app to a custom app later? Yes, you can migrate from a readymade app to a custom app later. The key is whether you can export your data in a usable format like CSV or JSON. Plan the migration early and confirm export options before buying any readymade tool. ### Do I need a contract for a readymade app purchase? Yes, you enter a contract when you buy a readymade app, but it is usually a clickwrap agreement from the provider. Read the terms carefully. Check who owns your data, how long they keep it, and whether you can export it at any time. ### How much control do I have over branding in a readymade app? Control over branding in a readymade app varies by tool. Some let you upload your logo, change colours, and pick fonts using a form builder. Others offer no branding options. Always test the builder before buying to confirm what you can change. ### What support comes with a custom app after launch? Support for a custom app depends on your contract. Common options include bug fixes for 3 to 6 months, hosting setup, and minor updates. Long-term support like feature upgrades or server maintenance must be agreed and priced separately. Define this before signing. ### What support comes with a readymade app? Support for a readymade app depends on the provider. Check their response times, update frequency, and escalation paths. Paid plans often include email or chat support. Free plans may offer only community forums or no support at all. ### Can I customise a readymade app? Yes, you can customise a readymade app if its architecture and commercial terms support the required change. Many no-code tools offer drag-and-drop builders to change forms, layouts, and branding. Complex changes like new workflows or integrations may not be possible. ### What are the risks of a readymade app? Possible risks of a readymade app include vendor lock-in, sudden price hikes, or the provider shutting down. Your business may also outgrow the app if it cannot handle unique workflows. Check the provider's track record and exit options. ## Related - [Comparisons](https://sachinsharma.work/compare/) - [Home](https://sachinsharma.work/) - [Contact](https://sachinsharma.work/contact/)
