What we hear from amazon sellers

What Amazon sellers tell us is broken

These are the recurring pain points we hear from Amazon sellers who run between 500 and 50,000 orders a month on Amazon UK.

Oversells between Amazon and other channels

Stock sells on Amazon before the sync on another platform fires, oversells the other channel, costs an A-to-z claim or an eBay defect.

FBA inventory that doesn't reconcile with FBM stock

FBA fulfillable inventory is separate from merchant-fulfilled stock, but most platforms can't model both against the same SKU cleanly.

Per-user pricing that punishes growth

Adding warehouse staff, pickers or a VA shouldn't add hundreds to your monthly bill. Some platforms charge per active user per month.

Quote-based pricing with surprise renewals

You can't plan if your renewal could double without warning. You need published rates that apply to every seller of your size.

Amazon Shipping labels buried in another tool

You want to quote, buy and print Amazon Shipping labels in the same place you dispatch Royal Mail and Evri — not in a separate tab.

Software built for the US, UK bolted on

Dollar-first currency, US holiday calendars, no UK VAT handling, support hours in PST. You need UK-hosted, GBP-first, UK-built.

The MaxInvent fix

How MaxInvent solves it for Amazon sellers

Every capability below ships in the box at every paid tier — no add-ons, no per-user fees, no extra modules to license.

Bidirectional Amazon SP-API sync

Stock pushes to Amazon within 30 seconds of a change. Orders pull every 10 minutes. FBA inventory is modelled separately from FBM stock against the same internal SKU.

See marketplace integration

Auto-split between FBA and FBM

Rules route orders by channel, weight, product, postcode or stock level. Prime orders go FBM when FBA runs out, B2B orders go direct from warehouse, everything else goes the cheapest route.

Auto-split guide

Amazon Shipping labels in the dispatch screen

Rate-shop Amazon Shipping against Royal Mail, Evri, DPD and Yodel in the same workflow. Print the cheapest label without switching tools.

Oversell prevention across channels

Central stock is the source of truth. When Amazon sells a unit, eBay, TikTok Shop and Temu are decremented within seconds. When stock runs out, every channel is pulled.

How sync works

Transparent per-order pricing, not per-user

£149/month covers 1,000 orders. 10p per order over that. Add as many pickers, VAs and warehouse staff as you want — same price.

See pricing

UK-hosted, GBP-first, GDPR-ready

All data is stored in AWS London (eu-west-2). GBP is the default currency, UK VAT handling is native, support operates in UK business hours.

How it runs

A typical day for an Amazon seller on MaxInvent

This is the default dispatch loop. Every step is configurable — these are the defaults most Amazon sellers settle on.

  1. 1

    Orders pull in from Amazon SP-API

    Every 10 minutes

    Every 10 minutes, new Amazon UK orders land in the dispatch queue. FBM orders come through straight away; FBA orders are tagged for reporting but not dispatched by you.

  2. 2

    Auto-enrich runs in the background

    Seconds

    Customer names, shipping addresses, product weights, SKUs and courier rules are pulled from Amazon + your master product catalogue. Any missing fields are flagged for a one-click fix.

  3. 3

    Auto-split assigns the correct warehouse and courier

    Automatic

    Rules decide which warehouse picks the order and which courier ships it — Amazon Shipping, Evri, Royal Mail, DPD, or bring-your-own.

  4. 4

    Pick, pack, scan

    Your SLA

    Pickers work from a printed or tablet pick list, scan each item at pack time to confirm, and labels auto-print on dispatch.

  5. 5

    Tracking and stock sync back automatically

    < 60 seconds

    The tracking number is pushed to Amazon the moment the label prints, stock is decremented across every channel, and the order is marked shipped.

FAQ

Questions amazon sellers ask

Does MaxInvent work with Amazon FBA as well as FBM?
+
Yes. MaxInvent pulls FBA fulfillable inventory separately from your merchant-fulfilled stock, against the same internal SKU. You can see both views on one screen, set auto-split rules that fall back from FBA to FBM when FBA runs out, and report on channel mix across your catalogue.
How does MaxInvent compare to Amazon's built-in tools?
+
Amazon Seller Central and the Amazon Shipping dashboard only see Amazon. MaxInvent is the single dashboard across Amazon, eBay, TikTok Shop, Temu, Groupon and ClearanceFood — so stock, orders and dispatch are handled in one place rather than five separate tabs.
Is MaxInvent UK-hosted? Does data leave the UK?
+
Yes, UK-hosted. All databases and uploads live in AWS London (eu-west-2). Data is never shared with US tenants. Each MaxInvent customer runs on an isolated PostgreSQL database — never a shared schema.
How does pricing scale as I add Amazon volume?
+
Starter is £149/month and includes 1,000 orders across all channels. Growth is £399/month and includes 5,000 orders. Scale starts at £999/month and covers 20,000+ orders. Every plan has a flat 10p/order overage — no surprise renegotiation. Pricing is published on every page.
Can I keep Amazon Shipping as my primary courier?
+
Yes. MaxInvent treats Amazon Shipping as one of many couriers in the dispatch screen. You can make it the default for all orders, for a specific channel, for a specific weight band, or only when it's the cheapest option at pick time.
How long does it take to migrate from another platform?
+
Most Amazon-heavy sellers are running real orders through MaxInvent within 7 to 14 days. We export your product catalogue from your current platform, map SKUs, connect Amazon and one additional channel as a pilot, and only move the rest once the pilot is clean.
Do I need a separate repricer?
+
MaxInvent does not replace a dedicated repricer like BQool or Aura. We recommend running a specialist repricer for aggressive Buy Box strategies and letting MaxInvent handle inventory, orders, dispatch and multi-channel sync. The two are complementary.
