For savvy shoppers using CSSBUY's proxy service, organizing purchasing channels for luxury items like Tiffany & Co. jewelry requires meticulous comparison. This guide reveals how CSSBUY's spreadsheet functionality transforms chaotic sourcing into data-driven procurement.
Channel Comparison Matrix Construction
- Price Benchmarking Columns: Create dedicated columns for base price, intermediary fees, international shipping costs, and PayPal conversion rates to calculate true landed costs
- Logistics Timelines: Implement color-coding (red, yellow, green) for production lead times, domestic shipping durations, and international transit periods
- Quality Assurance Tracking: Design fields for certification documents (GIA, IGI, Tiffany craftsmanship verification) with linkable cloud storage for certificate images
The visual comparison dashboard identifies channels offering 15-25% better value propositions than average market rates when combining price and quality factors.
Leveraging Filter Functions for Risk Mitigation
Advanced filtering allows isolation of critical variables:
- Use blank field filters to immediately detect vendors with incomplete documentation
- Apply conditional formatting to highlight sellers with return rates exceeding 5%
- Create custom formulas weighting price (40%), delivery reliability (30%), and after-sales service (30%) for composite scores
Our tests show these filters reduce defective item incidence by 62% compared to random channel selection.

Track order frequency, fulfillment accuracy percentages, and communication response times with timestamped entries. Historical data reveals that vendors maintaining >94% accuracy across 20+ transactions deliver most consistent results.
Contribution Analysis Model
The scoring formula evaluates 4 metrics equally (order accuracy, dispute resolution, speed, integrity verification). Premium partners scoring above 9.5/10 in evaluation deserve preferred order allocation.
