Multichannel Commerce ERP

Run your entire online business from one place.

Inventory, orders, listings, shipping, accounting and CRM — unified across every marketplace, shopping cart and social shop you sell on. One system instead of five subscriptions, and it's live in days, not months.

Why "90Twenty"? 90 + 20 = 110%. Because good enough stops at 100.

Every channel. One inventory. One truth.

Connect the places you already sell. Orders flow in, quantities and prices flow out, and every channel always agrees with your warehouse.

Yours isn't here?
We'll build it.

TikTok Shop and Facebook & Instagram connect through your Shopify or BigCommerce store's official channel apps — their orders flow in through your store connector today, the same way every major platform does it. Don't see your channel live yet? New connectors are built for you in days — included with your plan, not quoted as a project.

…and it sends from your email.

Purchase orders, invoices, statements and campaigns go out from your own mailbox — your address, your reputation, replies straight to your team. Guided setup, not server settings: pick your provider and the technical part fills itself.

Standard SMTP under the hood — if your email provider isn't listed, it almost certainly still works. A one-click test email proves your mailbox before anything depends on it.

Never oversell again.

One quantity, recomputed from the truth on every order event, pushed to every channel. The overselling that burns marketplace accounts simply can't happen here.

  • Real-time sync everywhere — a sale on Amazon updates eBay, Walmart, Shopify and Newegg in the same breath.
  • Committed-stock guard — unshipped orders reserve inventory so two channels can't sell the same unit.
  • Serialized tracking — know exactly which unit shipped to which customer, forever.
  • Closest-warehouse routing — orders auto-assign to the nearest warehouse that can fill every line.
  • Cycle counts built for speed — scan-first counting your team can bang out without stopping the day.
  • Dropship & vendor-feed warehouses — sell vendor stock at markup without it ever touching your books.

Books that close themselves.

Full double-entry accounting isn't bolted on — it's the same system. Every shipment posts revenue, cost and fees the moment it happens.

  • Exact marketplace fees, per order, at order time — the same number Amazon puts in its own email, on your order screen and P&L. No week-late settlement surprises.
  • Net profit on every order — price − cost − fees − shipping label, right on the order.
  • Automatic postings — revenue, COGS, A/R, clearing accounts, even Stripe payout deposits book themselves.
  • Reports that tie out — Net Revenue, Marketplace Fees, Top Movers with margin, Shipping Spend.
  • Invoice & get paid — Stripe payment links (card + ACH) that post themselves when paid.

Shipping that pays for itself.

Built-in rate shopping with discounted carrier rates — including flat-price 2-day options — and a buy-label flow that finishes the whole job.

⚖️

Rate-shop every label

Every carrier and service in one cheapest-first list, flagged against the marketplace's delivery promise. Signature and insurance reprice live before you buy.

One click does it all

Buying the label ships the order, prints the 4×6 pack, and pushes tracking back to the marketplace automatically. Batch mode does a whole queue at once.

💰

Discounted rates included

Ship on our negotiated parcel rates — with flat-price 2-day services that beat dimensional pricing — plus LTL freight quoting and booking for the big stuff.

Automation with a brain.

The busywork runs itself — and the AI never invents a fact about your products.

🤖

AI Listing SEO

Search-optimized titles, descriptions and product copy written from your data — never invented specs — refreshed automatically when products change.

📈

Automatic repricing

Win the Buy Box with guardrails: floors you set, competitor-aware ladders, and no race to the bottom.

📦

Automatic purchase orders

Dropship sales auto-create the vendor PO. Serialized receiving, partial receipts and vendor returns included.

✉️

Automatic customer emails

Order confirmations, shipping notices with tracking, and branded invoices — sent from your own domain.

🏷️

Quantity discounts, everywhere

Set volume pricing once — it syncs to Amazon, eBay and Shopify as native tier pricing on each channel.

🔁

Self-healing syncs

Missed fee? Failed tracking push? The system notices and retries until it's right — without you.

CRM & marketing, included.

  • Customers & vendors with terms, tax codes, credit limits and full history.
  • Interest categories that tag every contact — then target email campaigns by what they actually buy.
  • Bulk import/export everything — with update-on-match so your spreadsheets stay useful.

Your ideas ship. 💡

A suggestion button lives at the top of every page. Ideas go straight to the development team — and features requested by customers ship weekly, not yearly.

  • Suggest from any screen — we see exactly where the idea came from.
  • Watch it move — reviewed → planned → shipped.
  • A roadmap driven by sellers, because it's built inside a live operation, not a boardroom.

Live in days. Not months.

ERP migrations are famous for taking a year. Ours is a guided, step-by-step protocol with bulk imports built for speed — the fastest path to live of any software in the category.

Built inside a real warehouse.

90Twenty wasn't designed in a boardroom. It runs a live multichannel operation every single day — the same orders, labels, fees and month-ends you deal with. When something slows a packer down or a penny doesn't reconcile, it gets fixed at the source. Then you get the fix.

Need something custom?

API integrations, EDI, a connector we haven't built yet, or a module that only your business needs — custom development is a first-class service, not an upsell maze.
