SaaS or custom software: which should your business choose?
Compare SaaS with custom software, understand the cost and risk, and choose the right approach for your processes, budget and growth.
Understand business app maintenance cost in India, what monthly support covers, why quotes differ, and how to choose the right plan for your team.

Business app maintenance cost in India depends on the work your app needs, not only on the number of screens. A small internal app may need occasional fixes, while an app handling payments, bookings, stock, delivery, and messages needs regular technical attention.
You may pay through a fixed monthly retainer, an hours based support plan, or separate invoices for each request. The right choice depends on your users, connected services, business hours, and the response time you need when something fails.
There is no single maintenance price for every business app. A vendor will usually look at the app type, number of users, operating systems, hosting setup, integrations, support hours, and expected response time before preparing a quote.
For example, a staff attendance app used by one office may have limited support needs. A retail app may need order processing, payment confirmation, stock updates, delivery status, customer notifications, and admin reports to work together. Each connected part creates another point that may need testing and support.
The platforms you support also affect the work. An app for Android alone has a different maintenance requirement from one that supports Android, iPhone, tablets, and a web dashboard. Older devices, different operating system versions, and changes in app store rules can increase testing time.
Ask every vendor to separate the following items in the proposal. This makes it easier to compare two quotes that appear to offer the same service.
A fixed monthly retainer can suit a clinic that needs regular booking support or a school that collects fees online throughout the year. Pay as needed support may suit a small business with few users and only occasional changes after launch. If you expect frequent requests, a retainer can make budgeting easier and give the vendor time reserved for your app.
Bug fixing deals with problems in features that already exist. These may include a patient who cannot complete a booking, a total that changes after applying a discount, a user who cannot reset a password, or a manager who does not receive an approval notification.
Ask how the vendor decides whether a request is a bug or a new feature. If the approved design says a booking can be cancelled but the button does not work, that is normally a bug. If you later want automatic refunds, multiple cancellation rules, and a new cancellation report, that is likely new development.
Platform maintenance keeps the app working when connected services change. Android and iOS release updates, browsers change behaviour, payment gateways update their requirements, and hosting providers alter settings. A payment screen that worked last month can fail after a service change even when your team has not edited the app.
Security and performance work should also form part of the discussion. This may include updating software libraries, reviewing user access, checking backups, monitoring errors, checking slow pages, and finding background tasks that have stopped running.
A business app can appear normal while important work fails in the background. For example, a retailer may receive an order on screen but fail to send it to the warehouse, or a school may show a successful fee payment without updating the student account. Monitoring helps your team find these problems before customers report them.
Content updates and small changes are often included only up to a stated limit. A clinic may need doctor schedules, fees, and holiday hours changed. A retailer may need product categories, delivery rules, or banners updated. Confirm who makes these changes, how many requests are included, and what happens after the limit is reached.
New functions should normally be estimated as separate development work. Adding subscriptions, a loyalty scheme, a new language, or a warehouse workflow changes the product and may affect the database, user interface, testing, and training. Hiding that work inside a maintenance fee makes the agreement unclear for both sides.
A low monthly fee may cover only a small number of support hours. Check what happens when those hours are used, how extra work is charged, whether the vendor needs your approval first, and whether unused hours carry forward.
A quote can also look cheap because it excludes the work that matters most. A vendor may include minor text changes but charge separately for app store releases, database work, server issues, or payment gateway failures. Read the exclusions as carefully as the included services.
Response time matters when the app supports a daily business process. A school may be unable to collect fees during an enrolment period. A clinic may stop receiving bookings during a busy day. Ask for separate response and resolution targets for urgent, normal, and low priority issues.
Response time is not the same as resolution time. A vendor may acknowledge a failed payment within an hour but need longer to identify the cause and release a safe fix. Your agreement should explain both targets and what information your team must provide.
Avoid an arrangement that depends on one developer knowing everything. If that person becomes unavailable, your business may lose access to essential knowledge. Ask for documented code, deployment access, backups, service credentials, technical notes, and a clear handover process.
Do not pay for a large support package if your app has few users and rarely changes. A smaller plan with emergency support may be more suitable. Review the plan when usage grows, new branches start using the app, or the app becomes part of a critical sales or service process.
Security updates should not be treated as optional. An old software library, weak user permission, expired certificate, or changed service connection can cause failures and expose business data even when the app itself has not changed.
A good proposal should describe the service in terms your team can check. You should know what is included, who responds, what gets tested, and what you pay when the request falls outside the agreed service.
Before signing, share three real situations from your business. For example, describe a failed payment, a booking error, and a new tax rule that changes invoice calculations. Ask the vendor to show which part of the agreement covers each situation, who acts first, and what may cost extra.
Also ask how work is prioritised. A spelling mistake in a product description should not receive the same urgency as a payment failure. A clear priority system helps your team make sensible requests and prevents every issue from being marked urgent.
Before requesting quotes, list your current users, platforms, integrations, support hours, business critical features, and planned changes. Dotdunia can help you plan a practical maintenance arrangement or build the app it supports through a conversation at www.dotdunia.com.
