Deadlines keep moving
Each release date slips, and the explanation is always a new one. Months pass without a version you can use.

Signs you need a rescue
When a system starts working against you.
If two or more of these sound familiar, an outside review usually pays for itself. Each one links to a project where we dealt with it.
The numbers do not add up
Reports, salaries or invoices come out wrong, and someone fixes them by hand every month.
See OSKI Time & CRM · salary logic and reports fixed
The app crashes after a few hours
Memory grows until the app falls over, or data sync breaks when two records clash.
See OSKI Time & CRM · now 8+ hours without a crash
It runs on a version nobody supports
The system sits on .NET Framework or an old Umbraco release. Security patches get harder, and plugins have no upgrade path.
See Jongeneel · Umbraco 8 to 17, .NET 10
Every change breaks something else
Small requests take weeks because nobody is sure what a fix will touch. Your team avoids parts of the code.
See One Motion ERP · changes ship without breaking production
The developer is gone
The person or agency who built it left, stopped answering or moved on. Nobody else knows how it is deployed.

How a takeover works
Audit, stabilize, document, plan.
Taking over someone else’s code goes wrong when the new team starts adding features on day one. We start by understanding what is there and making it stable. Only then do we talk about what comes next.

- Audit the code and the infrastructure
We get access to the repository, hosting, databases and logs. We read the code, check how it is built and deployed, and list what is broken, what is risky and what is fine.
- Stabilize first
Crashes, wrong numbers and failing jobs come before new features. We fix what hurts daily work and add tests around the logic we touch.
- Document what we find
How to build it, how to deploy it, where the data lives and which parts are fragile. Written down in your repository, so the knowledge stays with you.
- Plan the next steps
You get options with trade-offs: keep and improve, upgrade the platform, or rebuild. Sometimes a rebuild is the cheaper path, and we say so.
- Support and extend
Bug fixes, updates and small features on an agreed schedule, with the scope and response times set in the contract.
Client story
Six months of delays, then a rebuild in two.
A small AgTech company in Manson, Washington, offers targeted crop treatment with automated drone spraying. A previous developer had delayed and mishandled its software project for more than six months. The owner found OSKI through an online search.
- One OSKI engineer took over the project in May 2025.
- The codebase was rebuilt from scratch with current practices, so it can be maintained for years.
- The project was delivered on time and on budget by the end of June 2025.
“What stood out most was their commitment to delivering a functional and reliable solution, no matter the challenges.”

Ongoing support
What we look after once the system is stable.
Scope, hours and response times are agreed per contract. These are the three kinds of work most support agreements cover, alongside monitoring of logs and background jobs.
Fix
Bug fixes and production issues
When it matters: Something breaks in a live system and the business needs it fixed, not explained.
Investigation, a fix, a test that covers it and a release. Urgent issues go through the channel and hours you agree with us up front.
Update
Security and framework updates
When it matters: Packages, runtimes and the CMS fall behind, and each skipped version makes the next upgrade harder.
Planned updates of .NET, Umbraco and third-party packages, tested before release, with larger upgrades scoped as their own projects.
Extend
Small features and change requests
When it matters: The business keeps sending requests: a new form, a report change, a field in an integration.
Small, steady releases that fit the existing code and components, so the system keeps up with the business without a big project.
Production support can be the main job, too. For a manufacturing and shipping business we develop and support its ERP, fixing invoice calculations, order mismatches and concurrency errors as they surface. For a US consultancy we helped quickly when short-turnaround work came in, over four years of white-label delivery.
Legacy upgrades
Old Umbraco and .NET Framework, moved forward.
Jongeneel, a transport company, runs inspections, toolboxes and transport planning on an internal platform. We moved it from Umbraco 8 and .NET Framework to Umbraco 17 on .NET 10. A deprecated plugin was replaced with an equivalent, and xUnit and Moq tests kept checking the business logic the whole way.

Support FAQ
Maintenance and rescue questions buyers ask us.
Anything missing? Send us your question and an engineer will answer, usually within one business day.
Contact usCan you take over a project another developer left unfinished?+
Yes. For a small AgTech company in Washington, a previous developer had delayed and mishandled the project for more than six months. One OSKI engineer took it over in May 2025, rebuilt the codebase from scratch with current practices and delivered it on time and on budget by the end of June.
Will you fix our existing code or rewrite it?+
It depends on what the audit shows. Often the code can be kept and stabilized, as with our own time-tracking platform, where we fixed salary logic, sync conflicts and memory leaks. Sometimes a rebuild is cheaper and safer, as it was for the AgTech project. You get the reasoning and the options before we commit to either.
What does ongoing support include?+
What we agree in the contract. Typical scope covers bug fixes, security and framework updates, small features and change requests, and monitoring of logs and background jobs. Larger upgrades or new modules are usually scoped and estimated separately.
What response times do you offer?+
Response times, support hours and the channel for urgent issues are agreed per contract, based on how critical the system is and the time zones involved. We do not quote one fixed number for every client. HS High Stake, a long-running client, noted in its review that the team was reachable for urgent tasks.
Can you support an old Umbraco or .NET Framework system?+
Yes. We work on code that spans .NET Framework 4.8, ASP.NET Core 3.1 and .NET 5 in the same portal, and we moved Jongeneel’s platform from Umbraco 8 and .NET Framework to Umbraco 17 on .NET 10. Tests kept checking critical logic during that move.
How is maintenance and support priced?+
Our rate listed on Clutch is $25–49 per hour, and the minimum project is $1,000. Ongoing support usually runs monthly, either as a dedicated team or as individual engineers. A defined rescue or upgrade can run as a fixed-scope, fixed-price project.
What do you need from us to start?+
Access to the source code, hosting and databases, any documentation that exists, and a person who knows how the business uses the system. If the previous developer is unreachable, we start from the code and the running system and document as we go.
