1C Enhancements Without Turning the System into a Monolith

Every 1C enhancement must be checked for its impact on upgrades, data exchanges, performance, and process owners.

We review the existing custom code, separate truly needed logic from legacy enhancements, and design changes so they do not break upgrades or create a new dependency on the unique knowledge of a single developer. In our experience, in most problematic 1C systems, enhancements were made directly in the standard configuration: the system was removed from support, and every update turns into a manual merge with the risk of breaking everything.

That is why, before any enhancement, we do four things:

• We decompose accumulated custom code and compare it with the standard configuration: what is actually used, what duplicates built-in mechanisms, and what is dead.
• We implement new logic as configuration extensions rather than edits to standard objects, so the configuration stays supported and upgrades normally.
• Removing objects from support is allowed only as a last resort, with the reason and support plan documented.
• For each enhancement, we identify the process owner and check the impact on data exchanges, reporting, and performance.

If an enhancement involves heavy calculations, integrations, data marts, user portals, or nonstandard workflows, we consider a dedicated service with loose coupling through API or ESB.

The business gets the function it needs, while IT keeps control: you can upgrade, disable obsolete scenarios, monitor errors, and evolve the landscape without a full 1C rewrite. This is how we helped clients get out of situations where maintaining a custom configuration cost more than rewriting it from scratch.

What changes after cleanup:

• The standard configuration is updated normally with one click, not through manual merging of releases with custom code.
• Enhancements are isolated in extensions or dedicated services: an error in one function does not stop the rest of the processes.
• An unused function is turned off together with its service, instead of consuming resources and generating errors for years.
• The system can be supported by any 1C specialist using the documentation, not just the author of the legacy enhancements.
• Errors in enhancements and data exchanges appear in monitoring before users report them.
