Mercado Livre CHEIO DE BUGS! Vendas Caindo? Veja Como Resolver

Summary

The video discusses widespread Mercado Livre bugs that sellers say are disrupting listing visibility, fulfillment, advertising, promotions, and sales. The guests describe updates being rolled out in batches, with some accounts affected months after others. Because errors can be account-specific and support may be slow, the practical focus is on testing reversible fixes while monitoring listings and profitability.

Operational playbooks and recommendations

• Flex and Full fulfillment

  • For Flex problems, sellers reported success after disabling and re-enabling Flex, sometimes leaving it off for a while. In some accounts, the change had to be made listing by listing rather than in bulk.
  • For Full issues, one reported workaround was to remove the product from Full, change its stock quantity, restore the original quantity, and then add it back to Full.
  • These are reported workarounds, not guaranteed fixes.

• Multi-stock and ERP synchronization

  • Check the ERP’s available-balance rules and which warehouses are included in the integration.
  • Resynchronize ERP and marketplace inventory. Changing or refreshing relevant stock settings reportedly resolved some multi-stock errors.

• Unavailable or stalled listings

  • If an ad becomes unavailable, check whether its catalog linkage is intact. One seller recovered listings using the system’s recreate ad function to relink them to the catalog.
  • For a previously successful listing that stops selling without an obvious error, try a small edit to the technical specifications or description and monitor the result. The guests advised avoiding title edits because titles and keywords affect search visibility.
  • If an ad remains unavailable, pause and reactivate it, or recreate it where appropriate. The speakers cautioned that resets help in some cases, but not all.

• Automatic listing edits and product data

  • Review Sales Preferences and disable automatic ad-improvement settings if they are enabled. The guests said automated changes may alter titles, attributes, variation names, or product details, potentially damaging SEO, separating an offer from its main listing, or creating inaccurate product information.
  • They also recommended disabling automatic photo edits and checking whether the platform has reordered or replaced listing images. One seller said replacing all listing photos stopped unwanted image changes in that case.
  • Verify that the title, photos, color, and technical specifications all describe the same product. Mismatches can lead to buyer confusion and returns.

• Ads and promotions

  • If an advertising campaign’s delivery suddenly collapses, one reported workaround was to create a new campaign and move the listings into it.
  • Check promotion settings and actual sale prices regularly. Sellers reported cases where discounts appeared to change—for example, a planned 10–15% discount allegedly becoming 30–40%—with resulting margin losses.
  • Verify promotion eligibility and co-participation rules, including whether discounts apply differently to CPF and CNPJ buyers. Audit settlements rather than assuming the displayed promotion is being charged as configured.
  • The guests also noted that some new promotion and social-commerce features may not be available through the API, limiting automation.

• Shipping, inventory, and billing checks

  • Audit shipping deductions. Sellers reported cases where buyers saw shipping as paid, while the seller was charged as if shipping were free. Check transaction-level settlements for unexpected deductions.
  • Recheck package dimensions and weights when fees change. The speakers described claims of warehouse measurements or oversized Full packaging increasing shipping costs.
  • Monitor pickup schedules and label-release times closely, especially around Saturdays and peak periods. They reported inconsistent cutoff times and possible missed collections.
  • Some sellers reported invoice-series errors that blocked Full shipments or invoice issuance. Escalate these promptly and keep a record of affected orders.

• Support and escalation

  • Open a support case for account-specific errors, but keep a temporary operational workaround in place where possible. The speakers said support resolution could take weeks or months and that tickets do not always fix the issue.
  • Record screenshots, affected listing IDs, dates, settings, and financial impact to support diagnosis and escalation. The video emphasizes that general tips may not work for every account.

Business implications and examples

• Marketplace concentration creates operational risk: A platform-side bug can affect listings, ad delivery, fulfillment, and revenue at once. Sellers should regularly monitor availability, impressions, conversion, stock, fees, and promotion margins rather than relying on sales totals alone.
• SEO and catalog integrity matter: Automated title or attribute changes can remove important search terms or attach an offer to an unsuitable catalog entry. Incorrect product data can also trigger returns.
• Peak-season planning may be constrained by platform settings: The guests worried that daily shipping limits or collection issues could prevent sellers from meeting seasonal demand.
• New sales formats are evolving: Mercado Livre was rolling out Stories, clips, livestreams, and other engagement features, but availability varied by account and some tools reportedly lacked API access. These were discussed as opportunities and operational challenges, not as proven growth channels.
• No formal management framework such as OKRs, SWOT, or a GTM model was presented. The main approach was a practical troubleshooting loop: identify the symptom, test a reversible change, verify the listing or account afterward, and escalate unresolved account-level issues.

Metrics and timelines cited

These figures are examples reported by the speakers, not platform-wide statistics:

• Some sellers had experienced unresolved issues for two to three months.
• One case of ad delivery reportedly fell from around 100,000 daily impressions to 10, then 5, before stopping. The suggested workaround was to rebuild the campaign.
• One recovered account was described as doing approximately R$2 million per month.
• A seller with roughly 500 listings reportedly had to consider making changes one by one when bulk editing did not work.
• The guests gave a seasonal example in which sellers normally shipping 20–50 orders per day might need capacity for around 300 daily orders at peak. This was an illustration, not a measured forecast.
• Some regional visibility problems were said to last about 20 days.
• One invoice issue had reportedly prevented invoicing for three days.
• The guests described Saturday labels becoming available only after approximately 6 p.m. Friday, and cited collection times around 9:30–10 a.m. in one operation. They also mentioned unusual cutoff times as late as 11:30 p.m.
