20-day QC rankings
Compare shopping agents’ fulfillment efficiency to help you choose where to shop.
Which shopping agent has the highest observed 20-day new-QC rate?
KakoBuy had the highest observed rate: 54.4% (2,275 of 4,184 eligible product samples, across 6 of 6 weeks), for the 6 complete purchase weeks through 18 Oct 2026. This is an observed referral sample, not a guarantee for an individual order. Method and limitations.
New QC (quality-check) photos record warehouse inspection, a visible sign of fulfillment progress for that product. When a QCRadar user goes to an agent to buy a product, we track whether it gains new QC there within 20 days. A higher rate means this happened more often.

189 of 613 eligible product samples gained a new QC batch at Sugargoo within 20 days after a user went there from QCRadar to buy the product. That is 30.8%.
Included purchase weeks: 2026-09-07, 2026-09-14, 2026-09-21, 2026-09-28, 2026-10-05, 2026-10-12. Weeks with fewer than 30 samples or incomplete collection evidence are omitted; the weekly table explains each gap.

Select a week to inspect its value. Grey bars are not yet eligible; hatched gaps are excluded or missing.
Collection and date coverage
Recent collection evidence: sufficient for the current collector check. Checked when this snapshot was captured; it does not prove historical uptime.
81,074 / 81,074 received photos have an inspection date (100.0%) since 2026-07-01. 0 invalid future dates.
29,675 photos arrived at QCRadar more than 21 days after inspection. This is collection delay, not shipping time.
What this feed shows
The feed’s full per-SKU QC gallery is collected. It supplies one latest-entry date for the top-level dated preview, not per-photo inspection dates; gallery photos without a supplied date are stored without an inspection date and do not enter the dated rate, activity counts or the date-coverage audit. Old gallery objects may have been removed upstream.
Time from going to Sugargoo to buy the product until new QC: median 10 days; 80th percentile 19 days, from 226 observed outcomes in the included weeks. Outcomes without new QC or taking over 60 days are omitted. This timing does not determine the ranking.

What this feed shows
The feed returns only the latest QC batch for a product. A missed batch may never be recoverable. Inspection dates use the supplied QC date; some historical dates were reconstructed.
Time from going to LoongBuy to buy the product until new QC: median 20 days; 80th percentile 28 days, from 141 observed outcomes in the included weeks. Outcomes without new QC or taking over 60 days are omitted. This timing does not determine the ranking.

Not currently ranked: GTBuy, RizzitGO. Their available data does not currently meet the ranking requirements. How platforms qualify.
Rates combine eligible weeks by sample count. Each included week needs at least 30 purchase samples. Platforms with fewer included weeks or samples have less evidence; expand a row to see the exact weeks.
*Median time is measured from going to the agent to buy until new QC, among observed outcomes within 60 days. Missing outcomes are excluded. See how the ranking works for sampling and collection limits.
Why 20 days?
We use 20 days as a shared checkpoint for purchasing, seller dispatch and warehouse QC. The window was informed by historical QC timing and gives every platform the same observation period, so longer waits remain visible.
If an order you placed still has no QC after 20 days, two useful questions to ask the agent are:
- Has purchasing, seller dispatch or warehouse processing been delayed?
- Was the product purchased from the seller I selected, or fulfilled from the agent’s own stock or another source?
The ranking cannot establish which explanation applies. A purchase that was never completed, unpublished QC or a missed collection can also leave us without an observed QC record. Treat the rate as a reason to check progress and sourcing, rather than proof of a specific cause. How we chose the window.
Common questions
What does the 20-day new-QC rate mean?
It is the share of eligible product samples, sent from QCRadar to that shopping agent to buy, that gained a dated QC record at that agent within 20 days. One product and one agent on one Beijing calendar day counts as one sample.
Why 20 days?
20 days is a shared checkpoint for purchasing, seller dispatch and warehouse QC. It gives every platform the same observation period and is a comparison benchmark, not an industry deadline or a delivery promise.
Why is a platform not ranked?
A platform is not ranked when it has no eligible week: fewer than 30 purchase samples, incomplete collection evidence, or missing or invalid inspection dates. An unranked platform is not shown as 0%.
Does a low rate mean my order was lost or not shipped?
No. The rate is an observed referral sample. It cannot confirm that a purchase completed, identify the buyer’s specific QC batch, or prove a cause. Ask the agent about processing delays and whether the item was bought from the seller you selected.
How often is this updated?
The report is refreshed daily and ranks the latest 6 complete purchase weeks. If the saved snapshot is more than 48 hours old, ranks are withheld until it refreshes.
Platforms not currently tracked
QCRadar has no active connected QC feed for these platforms, so they do not receive a rank. How platforms can connect.

Purchase samples now also include QCRadar cart imports, the browser extension and the Discord bot where the product identity is observable, alongside purchase links opened on QCRadar. Sugargoo’s full per-SKU QC gallery is collected; gallery photos without a supplied inspection date are stored without a date and are not used for the dated rate, activity counts or date-coverage audit. The 20-day window and ranking calculation are unchanged.
12 November 2026 · Method 2026-11-12.2
The public page ranks platforms by new QC within 20 days after a user goes there from QCRadar to buy a product. It uses the latest six completed purchase weeks, weighted by sample count. Weekly ranges, observed median times and omitted weeks are visible. Internal comparisons against a platform’s own history do not determine this ranking.
Known collection correction: OopBuy’s 20 July–7 September interruption is excluded, including overlapping observation windows. LoongBuy historical date recovery still leaves undated records; coverage is shown without treating missing dates as zero activity.
