Mainsail ERP

Built for Walmart, SHEIN, TEMU and Amazon sellers

Marketplaces differ. Your records should not.

Mainsail ERP connects sourcing, bulk listing, fulfilment and procurement reconciliation, so operations, buyers and finance work from one set of records.

Each marketplace, modelled on its own terms.

Listing fields, price review and shipping semantics are modelled per platform, so operators stop switching between seller back offices.

How it works

From capture to settlement, the trail is unbroken.

These are not four separate tools. Each stage hands its result to the next one, on the same record.

01

Source

Products captured from Amazon land in the sourcing library. AI retouching produces listing images, and blacklist rules block risky items before they move on.

  • AI sourcing library
  • Product blacklist
  • Image space
02

List

Pending products are organised per platform. Bulk repricing, stock edits and publish queues run in the background, with review results returning to the same view.

  • Pending queue
  • Task queue
  • Live listings
03

Fulfil

Store and marketplace orders arrive in one workspace, where procurement status, tracking numbers, returns and refunds stay attached to the order.

  • Store orders
  • PO returns
  • Refunds
04

Settle

Order settlement and procurement statements are generated per cycle. Approver, timestamp and amount differences are all recorded and exportable.

  • Settlement
  • Statements
  • Reimbursement

Five modules, shaped around what cross-border teams actually do all day.

The split follows real roles: operators watch listings and orders, buyers watch supply and statements, finance watches settlement, risk watches infringement.

Orders and fulfilment

Store orders, marketplace orders, returns and PO returns share one workspace. Filter by store, order status or procurement status, and read amounts, SKUs, tracking and order time on a single row.

Procurement and reconciliation

Warehouse purchase confirmation, supplier quotes, PO returns and statements move along one line. Every statement records the receivable, the settled amount, the approver and the timestamp.

  • Purchase confirmation and rejection
  • Statement generation and download
  • Reimbursement and credit ledger

Products and publishing

Pending, in review, published and rejected listings live in separate tabs, while bulk repricing and publish queues run in parallel.

Trademark patrol

TRO detection sweeps live listings in batches. Title risk, image risk and matched keywords produce a risk score, with takedown available inline.

AI and add-ons

AI retouching bills by credits, the risk engine flags exposure, and ASIN monitoring plus scheduled patrols keep running in the background.

Get sourcing right and the rest of the pipeline stops backtracking.

The sourcing library puts capture environment, source store, category, rating, review count, capture price and marked-up price on one table, so the decision happens before anything is pushed to a store.

Captured straight into the library

Products captured by the client land in your organisation library, viewable by platform or by store.

Retouch before listing

AI retouching produces white-background and lifestyle images, billed by credits, with output volume set in your retouch settings.

Push to pending in bulk

Select rows and move them into a target store queue, carrying size and category attributes along.

Security and governance

Multi-tenant by design, not by convention.

Data is scoped by organisation at the query layer, identity comes from the signed token rather than the request body, and every sensitive action leaves a record.

Organisation isolation
Every query is bound to the organisation, and store ownership is verified before order data is returned.
Role-based access
Menus and actions follow role. Settlement, member management and finance views are restricted to the roles that own them.
Operation logs
Logins, edits and bulk operations are written to an operation log that administrators can search.
Procurement statement list with statement number, organisation, status, order count, receivable, settled amount, approver and timestamps
Procurement statements keep approver, timestamp and amount differences on the record.

What onboarding looks like

Most teams go live on the first marketplace within a few weeks, then add platforms one at a time.

  1. 01

    Connect stores

    Authorise marketplace accounts and import existing listings and orders.

  2. 02

    Map your process

    Set roles, approval steps, price rules and blacklist rules to match how your team already works.

  3. 03

    Run one platform

    Go live on a single marketplace, verify listings, orders and statements end to end.

  4. 04

    Scale out

    Add the remaining platforms and stores, then turn on patrol and monitoring add-ons.
