Sanso + Back Market: Sales Reconciliation

Illustration of the Back Market integration: a marketplace payout broken down into sales, refunds, and commissions reconciled automatically

Back Market Drives Sales. But Reconciling Your Payouts Is Still on You

Back Market has established itself as the leading marketplace for refurbished goods, in France and beyond. You list your products, you reach people specifically looking for refurbished equipment, and the platform handles payment, buyer invoicing, and a good chunk of customer service. In short, when you sell on Back Market, you're running a real channel. Still, a well-designed Back Market integration can save you serious time on the finance side.

Still spending whole days breaking down your Back Market payouts by hand?

Sanso's AI splits each bulk transfer into orders, refunds, and commissions, and reconciles them in your accounting without a single manual entry.

The problem is that Back Market remains a marketplace, not a financial management tool. At regular intervals, you receive a bulk transfer, a payout, that bundles dozens, sometimes hundreds of orders, refunds, returns, and commissions charged by the platform. On your bank statement, all of it lands as a single amount. And the marketplace sales reconciliation work still isn't done. You have to break the transfer apart, trace each order, isolate the refunds, reconcile the commissions, then post it all cleanly into your accounting. Most sellers do it by hand, in Excel, and lose whole days to it. Others give up and end up not really knowing what happened.

I'm Amalia Bercot, co-founder and CEO of Sanso. That missing link is exactly what we take care of. Sanso is an AI-powered financial management service: our Back Market integration handles your marketplace sales reconciliation, breaks down each payout, and matches every line, continuously, without you having to check off a thing.

What Sanso Adds to Your Back Market Integration

Sanso isn't yet another piece of software to learn, and it doesn't replace Back Market. It's a service that works from your Back Market data, on your behalf. The AI is the engine that gets through the work: it retrieves the detail of your payouts, splits each bulk transfer into individual transactions, traces the order, refund, or commission behind each line, and posts the reconciled result into your accounting tool.

The logic comes in two steps. Back Market handles the sale and sends you your money; Sanso takes over the marketplace sales reconciliation and the sync with your accounting. Manual reconciliation almost always stalls on two things: volume, and discrepancies. A partial refund here, a commission that varies by product category there, a return processed on a different payment cycle. That's exactly where Sanso's AI makes the connection. On this type of marketplace reconciliation, our automated reconciliation rate runs around 96%. The few discrepancies that remain, our operators handle by hand, for full compliance.

And everything the AI processes stays visible where you already look: your sales in Back Market, your entries in your accounting software (Pennylane, Tiime, Axonaut, Xero). Nothing is hidden, nothing happens in some parallel interface you'd still have to learn.

How Sanso and Back Market Work Together

Automatic Breakdown of Every Back Market Payout

When a Back Market payout hits your bank account, Sanso's AI breaks it down line by line. It reconstructs what's hiding behind the bulk amount: every sale, every refund, every return, every commission charged by the marketplace. You go from an opaque transfer to a precise breakdown of what's inside it, without opening a single export file.

Sales Reconciliation with Your Accounting

Once the payout is broken down, the AI matches each line to its corresponding transaction and updates your accounting. Sales get recorded, refunds get posted to the right place, Back Market commissions get booked as expenses. The result: your revenue reflects the reality of your sales, not just the net amount that lands in the account. That's what lets you calculate your VAT correctly and track your real margin on refurbished goods.

Handling Refunds and Returns

Refurbished goods come with a much higher volume of returns and refunds than average. Sanso's AI treats them separately: it spots a refund, links it back to the original order even when it lands in a later payment cycle, and adjusts the entries accordingly. You keep an accurate view of what was actually collected, order by order.

Is your revenue just whatever net amount hits the account?

Sanso records every sale, refund, and commission at its true value, for accurate VAT and a real, trackable margin on refurbished goods.

Accounting for Commissions Charged by Back Market

Commissions vary by product category and by the terms of your marketplace contract. By breaking down each payout, the AI isolates the commission charged on each sale and books it as an expense at its exact value. You know what the marketplace really costs you, sale by sale, without pulling out the calculator over a corner of Excel.

Centralized Multi-Marketplace Reconciliation

Few sellers sell on Back Market alone. If you're also on Refurbed, Mirakl, Cdiscount, MediaMarkt, or selling through Stripe, Sanso's AI applies the same mechanics to all your channels and centralizes reconciliation in one place. One logic, one view, no matter which marketplace generated the sale.

Who This Back Market Integration Is For

  • Back Market sellers who receive bundled payouts and spend hours, or hand them off to someone else, breaking them apart by hand before they can be booked.
  • Refurbished-goods businesses drowning in refunds and returns, which are often painful to match to the right order.
  • Multi-marketplace sellers juggling Back Market, Refurbed, Mirakl, and the rest, who'd rather have unified reconciliation than one Excel file per channel.
  • SMB owners with 5 to 50 employees whose volume doesn't justify a full-time finance hire, but where marketplace reconciliation overflows anyway.
  • Office managers and CFOs who really don't have time to check every Back Market order against every payout line, month after month.

What Changes for You

  • Before: one bulk Back Market payout, impossible to read. After: the AI breaks it down into orders, refunds, and commissions on its own.
  • Before: you break down your marketplace sales by hand in Excel, over several days. After: reconciliation runs continuously, with around 96% automated matching.
  • Before: your revenue is just the net amount that lands in the account. After: every sale, refund, and commission is recorded at its true value.
  • Before: returns and refunds muddy your tracking. After: each one is linked to its original order, even when it comes in later.
  • Before: you're not quite sure what Back Market is charging you. After: every commission is isolated, booked, and readable, sale by sale.
