“Cheapest” has two honest definitions, the lowest price this month, and the lowest total across your next year of growth, and in multichannel software they point at different tools, because the cheap end of this category is built on meters: order caps, listing quotas, per-order overages, and auto-upgrades that convert your good months into invoices. Every number below comes from the vendors’ own published pricing (July 2026). Disclosure: Unifystock is our product, and it is deliberately not the cheapest sticker on this page; the case it makes is the second definition.
The cheap end, catalogued
Free tiers (samples, sized to end):
- Marketplace Connect: free to 50 synced orders/month, then 1% per order capped at $99, Shopify-only, no Etsy, the read.
- CedCommerce Amazon app: free to 50 orders, then $0.20 per order, per app, per marketplace, the app-stack math.
- Salestio: free plan with 10 lifetime orders, a demo wearing a plan’s clothes, then $29-$299 with per-order overages of $0.04-$0.15, the analysis.
- Koongo: a real free plan with per-tier caps, feed-first, EU-strong, the details.
- Veeqo: free forever, for labels; the multichannel inventory features are the paid, volume-priced tiers, the split explained.
Sub-$50 monthly entries:
- 3Dsellers from $19 (100 listings, eBay only; multichannel on the $79 tier plus $10 per account), the structure.
- LitCommerce from $29 (3 channels, 1,000 listings, counted per channel, 15-minute sync), the quota arithmetic.
- ExportYourStore from $29 (100-listing cap at entry, one source store, unlimited orders), the read.
- Sellbrite at $29 (100 orders/month cap; the free tier caps at 30), the tiers.
- Listing Mirror at $69 on annual billing (500 SKUs, 100 FBM orders, 3 channels, and auto-upgrade on overrun, the bill raises itself), the fine print.
- GeekSeller at $50 (50 orders, doubling to $100 at order 51, FBA/WFS orders excluded from caps), the details.
The growth math that flips the list
Take a seller at 800 orders a month across three channels with 600 listings, modest, real, and reprice the cheap end: Sellbrite needs the $179 tier (2,000-order cap), Marketplace Connect bills its $99 cap, CedCommerce meters per app, Listing Mirror has auto-upgraded twice, LitCommerce’s quota counts 1,800 listing-channels, and GeekSeller doubled at order 51 months ago. The stickers said $0-$69; the twelve-month bills say otherwise, the pricing-shape analysis formalizes the pattern: meters price your growth, and growth is the point.
Flat pricing inverts it: Unifystock never meters orders or listings on any plan. The $49 Standard connects your source store free plus two sales channels with event-driven sub-3-second sync and buffers, and the published tiers scale toward all six native channels (Amazon, eBay, Etsy, Shopify, WooCommerce, OpenCart) and beyond without a single per-order fee, with per-channel pricing and forecasting on the plans above. You pay for channels, not for growth. At 40 orders a month, the free tiers beat us honestly; from your first real growth month onward, the math swaps sides.
How to price any tool in five minutes
- Write next year’s numbers: orders/month, listings times channels, channel count.
- Apply their meter to those numbers, not this month’s, caps, overages, auto-upgrades, add-ons ($19 FBA at Sellbrite, $10 accounts at 3Dsellers).
- Add the sync tax: cheap tiers with slow cadence pay in oversell risk, a cost the invoice never shows.
- Check the exit: month-to-month beats annual lock-in at this end of the market; inkFrog taught the category that cheap vendors can simply vanish.
Common questions
What is the absolute cheapest way to start multichannel?
A free tier matched to your channel pair, Marketplace Connect for Shopify-plus-Amazon under 50 orders, CedCommerce’s Amazon app for a store-plus-Amazon test. Treat them as the samples they are.
Are the cheap tools worse software?
Not necessarily worse, differently shaped: the meter is the business model. You are not buying worse sync at $29; you are usually buying slower sync with a growth tax attached.
When does flat pricing win?
The month your metered bill would cross $49 and never look back, for most sellers, somewhere between 100 and 300 orders a month across two or three channels.
Is annual billing worth the discount?
Only on a tool you have already tested at your volume, run the sync test before prepaying a year anywhere, including with us (we bill monthly precisely so you do not have to trust first).
Cheapest across the year that matters
Unlimited orders on every plan, six native channels, flat tiers from $49: you pay for channels, not for growth. See pricing.
