Find the actual operational bottleneck
Follow an order from arrival to completion. Note copied information, missing files, approvals and points where someone must chase another person. Check whether the problem is missing functionality, inconsistent data or a working rule nobody has defined.
Another tool alone will not resolve unclear ownership. Choose the journey and its accountable person first. Use that description as the comparison scenario for each option.
Compare three routes
Configure the existing tool when it can already handle the journey but is poorly set up. Connect tools when useful systems work in isolation. Build a focused module when an important business rule does not fit those tools.
- Adapt: check available features, permissions and configuration limits.
- Connect: check API access, synchronization and error handling.
- Build: establish ownership, a source of data and maintenance responsibility.
Compare operating constraints too
For each option, ask how to export data, investigate a failure and restore service. Check required accounts, subscriptions, training and any duplicate entry that would remain. Migration and data cleaning need separate costing when excluded from the build.
GOV.UK recommends mapping existing systems and data, then testing interfaces during prototyping. This helps verify a connection before depending on it.
Test one workflow before replacing the system
Illustrative example: retain the current invoicing software while bringing customer requests, approvals and status into a portal. Test a small set of representative records with the people involved. Include an incomplete request and an unavailable connection.
Measure time spent on the journey and errors over a defined period. A hidden-cost estimate helps prioritize; it does not prove all that cost will disappear. Then decide whether to extend, correct or stop the pilot.
When to consider a broader ERP
A narrow need may justify a module. Shared accounting, stock and purchasing requirements may need a broader approach. If several teams depend on the same data, examine governance and cross-team rules before adding more tools.
Okys offers a first operations or CRM workflow in a 14-day sprint at €5,000 with approved scope. Half at launch, balance on delivery, code owned by you. Scoping establishes whether the format fits; it does not replace the assessment of a complete ERP.
Before you decide
- Document one real case from beginning to end.
- Compare configuration, integration and custom development using that case.
- Check exports, permissions, failures and maintenance ownership.
- Define what the pilot must demonstrate before extending it.
Common questions
Do we have to abandon our existing software?
Not necessarily. A workflow can use valuable tools already in place when their access and limitations allow a reliable connection.
Does a light ERP replace accounting software?
Not automatically. An operational module can support business processes without replacing accounting. Responsibilities and data transfers need explicit definition.
