Application Maintenance

We begin with an inventory. We list each application and integration: what it does, who built it, where it is hosted, what it connects to, who owns the accounts and what data it moves. For systems we did not build, we review code, documentation and access, and we record unknowns openly. We identify single points of failure, such as credentials held by one person, expired certificates or tools running on unsupported versions. We then classify each system by importance. An order sync that feeds invoicing needs fast response; a monthly report script does not. This guides monitoring and response times in the support agreement. Monitoring comes next. For each critical flow we set checks: scheduled jobs complete, queues empty, records appear in the destination, error logs stay clean and key totals match between systems. Alerts go to us and, if you prefer, to a named person on your side. We also monitor uptime, SSL expiry and server health where we manage hosting. We agree a routine. Monthly or quarterly we review logs, apply security and dependency updates in a test copy first where possible, run regression checks on key functions, and then deploy with a rollback plan. We keep backups of databases and files, store them separately, and test restoration so we know it works. When a connected vendor announces changes, such as API deprecations or new authentication rules, we plan updates ahead of time instead of reacting to breakage; this is common with CRM, payment, messaging and ad platforms. When an issue is reported, we triage it by impact, reproduce it, find the cause, fix and test it, then document what happened and how to avoid it. For repeated issues we recommend a permanent fix. We keep a change log and update technical documentation so that knowledge is not locked in one person’s head. We also advise on security: least-privilege access, strong authentication, removal of unused accounts and periodic review. If you outgrow a tool or it becomes risky to maintain, we say so and propose a migration plan; see third-party API integration and CRM and ERP integrations for how replacements are built. Reports summarise issues handled, updates applied, risks and recommendations. We cannot guarantee that no failures will occur, since vendors and the internet change, but monitoring and routine care shorten outages and prevent small faults from becoming costly ones.
