1. Define the required outcome
Write down essential steps, participating systems and acceptable failure conditions. Separate requirements from preferences. Name an owner who can evaluate the result. Complete this before comparing vendors.
2. Choose standard software when it fits
Can your current package or a standard tool meet the essential outcome at acceptable total cost? Make it the first candidate and configure only what is needed. Still check permissions, cost, data use and export.
3. Automate only the missing step
Do existing packages work well but handoffs need manual work? Assess a supported integration or limited workflow. An approved quote might receive a reminder and a CRM update. Check API access, duplicate actions and manual exceptions.
4. Justify custom development
Custom work is a candidate when necessary requirements cannot reasonably be met by existing options and value supports build, care and customer effort. Without an owner, testable scope or maintenance budget, investigate further or do not build. A high differentiation score cannot compensate for those gaps.
5. Compare costs and uncertainty consistently
Use the same period, user numbers and volumes for each option. Include implementation, licences, care, consumption, internal effort and switching. Consider low and high scenarios. Capacity becomes financial savings only when supported by a change in costs or revenue.
Three illustrative decisions
Payroll: first examine a standard package that meets requirements. Quote follow-up: check CRM capabilities before adding a workflow. An unusual operational process: compare a limited custom step with changing the process or not building. These are decision examples, not customer outcomes.
Check failures before choosing
Test a provider outage and repeated input. Platforms may support error handling; the n8n documentation gives an example. Allow work for setup and verification whether buying or building.
