Sellozo or SellerMate — which should you use?
Choose SellerMate if you want a conversational AI agent that analyzes and executes inside admin-set guardrails, MCP access for Claude and ChatGPT, inventory-aware bidding, DSP and AMC coverage, and a free forever plan — Growth is $149/mo or 1.5% of ad spend. Choose Sellozo if flat-fee certainty matters most: $250/mo for every feature on one marketplace (plus $50/mo per additional marketplace), no percentage of spend, with genuinely strong hourly AI dayparting built on Amazon Marketing Stream data. Both automate bids, harvesting and negatives; the deciding questions are pricing model and whether you want an AI layer you can talk to.
Choose SellerMate if
You want an AI agent that executes from chat inside server-enforced guardrails, MCP access for AI clients, bids that react to inventory levels, DSP and AMC in the same platform, SOV and digital shelf tracking, or a free plan rather than a trial.
Choose Sellozo if
You want one flat price for everything — $250/mo with no percentage of ad spend, which undercuts percentage-based models at high spend — plus hourly Marketing Stream dayparting that pauses and restores hours automatically, a visual Campaign Studio for harvesting flows, and a repricer and real-time P&L bundled in the same subscription.

An honest assessment
When Sellozo is the better choice
Flat-fee certainty at high ad spend
Sellozo charges $250/mo with no percentage of spend. Above roughly $17K/month in ad spend, that flat fee undercuts SellerMate's 1.5% Growth rule — at $100K/month the difference is $1,250 a month. If you are certain you only need what Sellozo bundles, the flat model is the honest winner at scale.
Dayparting is your main lever
Sellozo's hourly AI dayparting is a genuine flagship: Amazon Marketing Stream data, hourly ACoS heat maps, and automation that pauses the worst hours when a campaign hits 90% budget utilization and restores them as performance allows. If scheduling is the core of your strategy, their implementation is battle-tested.
You want repricing and P&L in the same tool
A rule-based Buy Box repricer and real-time profit-and-loss reporting (including Amazon's deferred settlement reserves) ship in the same $250 subscription. SellerMate does not include a repricer — if pricing automation matters to you, that is a real gap in our favor of Sellozo.
Visual campaign flows
Campaign Studio's drag-and-drop interface for keyword harvesting flows — moving targets between auto, broad, phrase and exact campaigns with custom transfer rules — is a distinctive way to see and control campaign structure, and Sellozo says agency users cite it as the feature they miss most elsewhere.

Frequently Asked Questions
Both automate bidding, harvesting and negatives, and both pitch hands-off management. Sellozo's edge is pricing simplicity — flat $250/mo with everything included — and hourly Marketing Stream dayparting. SellerMate's edge is the AI layer and breadth: a conversational agent that executes inside server-enforced guardrails, MCP access for Claude and ChatGPT, inventory-aware bidding, DSP, AMC, SOV and white-label agency reporting, starting from a free plan.
Sellozo publishes one flat plan: $250/mo for all features on one marketplace, plus $50/mo per additional marketplace, month-to-month with a 30-day trial (sellozo.com, September 2026). SellerMate publishes tiers: Free forever, AI at $30/mo, Growth at $149/mo or 1.5% of ad spend (whichever is higher), and custom Enterprise. Below roughly $17K/month ad spend SellerMate Growth costs less; above it, Sellozo's flat fee wins on price while SellerMate includes the AI agent, MCP, DSP and AMC that Sellozo does not describe.
Sellozo's hands-off mode is algorithmic: set a target ACoS, let its AI bid, harvest and daypart. SellerMate's is agentic: automation rules run continuously, and you can also ask the AI agent to analyze or change anything in plain English — with every write checked against policy guardrails your admin sets, optional approval queues, and a full audit trail. If you want to interrogate the automation ("why did spend spike Tuesday?") and act from the same conversation, that is the difference.
As of September 2026, Sellozo's public materials describe no MCP server or AI-client integration — its OzO beta chatbot answers help and product questions inside the app. SellerMate operates a free MCP server at https://api.sellermate.ai/mcp/sse, listed in Claude's connector directory, that gives Claude, ChatGPT, Cursor and other MCP clients live read access and guardrailed write access to your Amazon Ads account on every plan.
Both are strong and both use Amazon Marketing Stream hourly data. Sellozo automates dayparting against budget utilization — pausing the highest-ACoS hours when a campaign hits 90% of budget and restoring them later. SellerMate offers dayparting at target, campaign and placement level with budget pacing, includes it on the free plan, and pairs it with hourly heatmaps and a free public Dayparting Calculator. If dayparting is your only requirement, either serves you well.
Sellozo's current site ships expanded DSP reporting metrics, but DSP management is not offered on its current pages and its own positioning points advertisers above $200K/month toward enterprise tools with heavy AMC integrations (September 2026). SellerMate includes a DSP seat and reports on Growth and above, plus AMC audiences on Growth and Enterprise.
