Web, Mobile, SaaS and E-Commerce Maintenance
Maintenance shaped around the platform you actually run: a website, a mobile app, a subscription product or an online store. Each fails in different ways, and GullySystem maintains all four under one arrangement.
Maintenance Looks Different by Platform Type
A website, a mobile app, a SaaS product and an online store share the label 'software', but they break in different places and for different reasons. Treating them all the same way is why maintenance often misses what actually matters.
What Websites Need
Content and CMS Upkeep
Keeping the CMS, theme and plugins current so a routine update does not break the layout or a contact form.
Form and Lead Capture Reliability
Checking that enquiry forms actually reach an inbox or CRM, since a silently broken form loses leads without any error appearing.
Hosting and Certificate Renewals
Watching domain, hosting and SSL certificate renewals so the site does not go dark or show a browser warning.
What Mobile Apps Need
OS Compatibility
Testing against new Android and iOS releases, since an app that worked perfectly last year can crash on a phone updated last week.
App Store Policy Changes
Updating the app to meet new store requirements, target SDK versions or permission rules before it is removed from listing.
Crash and Performance Reports
Reviewing crash logs and slow-screen reports that only surface once real users are on real devices.
What SaaS Products Need
Billing and Subscription Edge Cases
Failed renewals, plan changes mid-cycle and proration errors that only appear for a handful of accounts out of many.
Multi-Tenant Data Isolation
Confirming one customer's data, settings and reports never leak into another's as new features are added.
Uptime for Paying Customers
Treating downtime as a customer-facing incident with its own priority, since it affects people who are actively paying for access.
What Online Stores Need
Checkout and Payment Gateway Changes
Adjusting to gateway API updates before checkout starts failing silently for some customers.
Catalogue and Inventory Sync
Keeping stock counts, prices and product data consistent between the storefront and whatever system holds the master data.
Peak-Load Days
Making sure the store holds up during a sale or festive period, when traffic is well above an ordinary day.
Frequently asked questions
Do you maintain more than one type of platform for the same business?
Yes. Many businesses run a website alongside a mobile app or an online store, and we maintain all of them under one arrangement so issues that touch more than one platform are not split across separate teams.
Does mobile app maintenance include re-submitting to the app stores?
Yes, when an update requires it. We handle the store submission and review process as part of keeping the app compliant and available.
What decides the cost across different platforms?
The number of platforms involved, the traffic or order volume each one handles, and how many third-party integrations, like payment gateways or SDKs, need to be kept current.
What decides how quickly a platform-specific issue gets attention?
How directly it affects customers or revenue. A broken checkout or a crash affecting many devices is worked ahead of a cosmetic issue on an internal page.
Do you need admin access to our payment gateway or app store account?
Yes, limited access scoped to what the work requires. The accounts themselves stay registered and owned by your business.
Can this run alongside a developer we already have in-house?
Yes. We can take specific platforms or issue types off an in-house developer's plate, or work alongside them on a shared backlog.
What do we need to hand over to start?
Access to each platform's code and hosting, admin logins for stores or gateways involved, and a sense of which platform currently causes the most trouble.
