Core capabilities built into WarrantyReserve Studio
When a customer files a warranty claim, you don't just lose the $14 replacement unit COGS—you also pay $7.95 in outbound replacement shipping, $2.85 in 3PL pick-pack labor, and $2.00 in RMA ticket inspection. Our studio calculates the true full-burden cost per claim.
Most overseas suppliers include a 1%–2% defect allowance, yet a single bad battery or zipper batch can push claims to 5.5%. Calculate the exact credit or free replacement units to deduct from your next factory balance payment.
Third-party warranty widgets take 65% to 75% of every $14.99 protection plan sold while your actual replacement cost is only $22. Model how self-insuring 1-year and 2-year replacement plans boosts net cart profit.
Uploading SKU failure rates and RMA logs to cloud warranty platforms exposes sensitive product quality metrics. Audit unlimited SKUs and supplier batches locally in your browser for a $19 one-time buyout.
Zero configuration, zero cloud server dependencies, instant execution.
Enter your SKU retail price, landed unit COGS, outbound replacement shipping & 3PL pick-pack cost, and historical 12-month warranty claim rate.
Simulate factory batch defect spikes (1% to 8%), test 2% free factory spare units on POs, and compare self-insured protection plans against third-party warranty revenue splits.
Generate an accounting-ready warranty reserve per unit sold and a documented factory defect chargeback summary for your next supplier PO.

Everything you need to know about privacy, local memory execution, and buyouts.
When you ship a free warranty replacement to a customer, you lose the replacement unit's landed COGS ($12–$35) PLUS outbound replacement postage ($7.50–$12.00) and your 3PL's pick-pack fulfillment fee ($2.50–$3.50). On a $14 COGS item with $9.00 reship fulfillment, each warranty replacement actually costs $23.00—making a 3.5% defect rate equal to 5.75% of COGS.
Multiply your trailing 12-month warranty claim rate by the full-burden replacement cost (Landed Unit COGS + Outbound Replacement Shipping + 3PL Pick-Pack Fee) for every unit sold. Holding this exact dollar amount ($0.75–$2.10 per order) in a dedicated reserve account prevents Q1 post-holiday warranty claims from distorting your monthly P&L.
Most manufacturing contracts include a 1% to 2% defective allowance (often provided as free spare units on the PO). When a bad component batch pushes observed warranty claims to 4.5% or 6%, you should charge back both the excess unit FOB cost and domestic reship expenses as a credit against your next production deposit.
For most DTC brands with landed COGS under $40 and defect rates below 5%, self-insuring a 1-year or 2-year accidental/extended replacement plan is dramatically more profitable. Third-party warranty providers typically keep 60% to 75% of the plan price, whereas self-insuring lets you keep 100% of the $9.99–$19.99 upsell revenue while funding replacements at your wholesale landed cost.
Never. All defect reserve modeling, supplier chargeback calculations, and CSV exports run 100% locally inside your browser. Your product defect metrics stay strictly confidential.
Instead of paying $129/month for RMA analytics software or surrendering 70% of your protection plan revenue, you get lifetime access to WarrantyReserve Studio for a one-time $19 payment (or €3.99 for a 24-hour pass), backed by a 14-day refund guarantee.
