If you sell on more than one marketplace, your cost structure changed while you weren't looking. In the last twelve months, several major marketplaces outside Amazon have raised seller fees β TikTok Shop's Brazilian arm raised its fixed per-item fee by 50% (R$4 to R$6) for items above R$50 in July, Shopee and Mercado Libre both raised seller fees in March, and Shopee shifted influencer-commission tax reporting onto sellers in Brazil. The pattern has a name: platforms spent years buying growth, and now they're raising prices (the direction isn't uniform β Shopee also cut video-campaign commissions β but the headline trend is up).
The US affiliate commission numbers point a related way: TikTok Shop's average US affiliate rate is 13.02% (source: Hamster Garage). Two balancing facts worth knowing: the US referral fee itself is still a flat 6%, and affiliate commissions are set by sellers, not imposed by the platform β the rising average reflects seller-set creator rates, not a platform fee hike. The question isn't whether fees go up. It's whether you're repricing your listings and margins on the schedule the platforms are on.
What actually changed, with numbers
TikTok Shop (Brazil, effective mid-July). For items under R$50, the commission rate went from 6% to 10% of sale price; the flat per-item fee is unchanged this round at R$4 (the R$2-to-R$4 change had already been priced in during 2025). For items above R$50, the commission stays at 6%, but the flat fee jumped 50% β from R$4 to R$6 per item β this round. When TikTok Shop launched in Brazil in May 2025, it waived seller commissions for 90 days and offered free shipping to compete (source: Valor International). The honeymoon is over by design.
Shopee (Brazil, effective August 1). Sellers become responsible for withholding and reporting taxes on the variable commission paid to affiliates and influencers, with a receipt required per service performed. Shopee also cut the commission it pays affiliates for video campaigns from 3% to 1.5% (while raising Shopee Live commissions from 3% to 5%). An accountant quoted in the reporting flags the practical burden: mid-sized sellers "typically rack up dozens of low-value invoices." One retailer put it more bluntly β "95% of sellers are solo operators or have just one or two people helping out" β and now carry the admin load.
Mercado Libre (March). Switched its Fulfillment pricing from a flat rate to a variable model based on weight, dimensions, and price β 11 of 15 pricing brackets got more expensive (source: Valor International).
TikTok Shop (US). The average affiliate commission rate is 13.02% (source: Hamster Garage). For the full seller fee breakdown, see Dashboardly's 2026 TikTok Shop fee guide.
What this means if you sell in one country (or three)
Two implications, neither of them limited to Brazil:
1. Fee increases arrive in waves, and the waves compound. Amazon's recent fee changes were one round. The platforms dominant in emerging markets β which spent 2023-2025 subsidizing seller acquisition β are now raising prices in another. If you price with a fixed margin assumption per platform, the assumption is already stale β and it will keep going stale on a quarterly basis.
2. The admin burden shifts to sellers. The Shopee tax-reporting change is the pattern to watch: platforms are moving compliance work to sellers while keeping margin. Any marketplace you're on can decide tomorrow that "the seller is the contracting party" for a cost you thought the platform absorbed.
The response isn't panic β it's recalculation. That brings us to the practical part.
The recalculation workflow (the part you can do this week)
Step 1: list your true per-platform costs. Commission, payment processing, fulfillment, storage, advertising, and now affiliate/influencer commissions. Most sellers can name the headline commission rate and nothing else.
Step 2: price in the fee schedule, not the current rate. When TikTok Shop Brazil moved the sub-R$50 commission from 6% to 10%, every listing priced under that threshold took a 4-percentage-point margin hit immediately after the mid-July effective date. If your spreadsheet prices at current rates, you're always chasing.
Step 3: track fee announcements like you track competitor prices. Marketplace fee schedules are data β they change on a schedule, they vary by market, and they're checkable. A monthly sweep of the platforms you sell on, logged against your SKU-level margin, turns a surprise fee hike into a 48-hour repricing decision.
Full disclosure: sorftime-seller-agent is built by our company, Sorftime β it's open source, with paid usage-based tiers for the underlying data.
A tool like the open-source sorftime-seller-agent fits this workflow on the data side: it connects MCP-compatible AI agents to marketplace data across Amazon, Walmart, TikTok Shop, Shopee, 1688, and TEMU β current price, sales volume, BSR, review structure β refreshed on the platform's update schedule (typically daily). Instead of maintaining a spreadsheet of "what did I sell where," you ask your agent a question and get the current numbers in the conversation:
# Install once (Python 3.10+ only)
git clone https://github.com/DannylydST/sorftime-seller-agent
cd sorftime-seller-agent && python3 scripts/install.py
# then merge the MCP config snippet the script prints into your agent's config
# (Claude Code/OpenClaw are auto-detected; for Codex/Cursor, build the
# MCP server entry manually from the repo README)
# Then, in your AI agent:
# "List my top 10 products by sales volume across TikTok Shop and Shopee.
# For each, show current price and sales volume, and flag any whose
# volume dropped more than 20% below its platform average this week."
The one-line takeaway
Marketplaces are repricing themselves, every quarter, in every market. The sellers who treat fee schedules as data β tracked, recalculated, priced in β are the ones who absorb the hikes instead of absorbing the surprise.
