NetSuite Customization Maintenance Cost Calculator

The model

Break-fix hours equal items x hours per item x the undocumented multiplier. Regression hours equal items x releases x hours per release x the same multiplier. Total cost is total hours x rate. The multiplier assumes undocumented items need around half again as much effort, which is an adjustable assumption rather than a measured constant. With 60 items, defaults give roughly 1,000 hours, which is a half-time developer, and shows why script sprawl becomes expensive.

• Multiplier = 1 + undocumented share x 0.5
• Break-fix = items x hours x multiplier
• Regression = items x releases x hours x multiplier
• Cost = hours x rate

Common mistakes

Teams often count only build cost and forget the recurring release testing. Another mistake is averaging all items, when a handful of complex integrations typically consume most of the effort. A third is treating documentation as overhead, when it is the main lever that lowers the multiplier.

• Track hours per script in your ticketing tool
• Name an owner for every script
• Retire scripts that standard features now replace
• Test release previews in a sandbox before the production upgrade
