Implementation Timeline

Time to launch (by platform):

Crosslist: 30 minutes (authorize 5 channels, map inventory, launch)
SECND: 45 minutes (authorize channels, set up team roles, test)

ROI: Will It Pay for Itself?

For most resale businesses, yes—within 30 days.

ROI math (example: $20K/year seller using SECND at $99/mo):
• Time saved: 8 hours/week (manual inventory tracking eliminated) = 32 hours/mo = $640/mo value (at $20/hr)
• Overselling prevented: 1–2 incidents/mo = $150–$300 loss avoided
• Total monthly benefit: $790–$940
• Platform cost: $99/mo
• Net benefit: $691–$841/mo
• Payback period: 1 week

At your revenue level, software investment pays for itself within 1–4 weeks. Everything beyond that is pure profit.
