Amazon USA Marketplace Reconciliation

Amazon marketplace reconciliation is the process of comparing your internal sales and finance records with Amazon reports such as settlements, payouts, fees, refunds, and returns. For finance teams, the challenge is not only matching totals. It is also understanding why transactions are unmatched, where deductions came from, and whether the final settlement agrees with the business records.

Cointab provides a structured reconciliation workflow for Amazon USA sellers and finance teams. It helps you upload reports, map key fields, run reconciliation, review matched and unmatched items, and download audit-ready Excel reports for internal review and period close.

Why Amazon marketplace reconciliation is difficult

Amazon reconciliation usually involves more than one report and more than one business question. A finance team may need to compare sales data, settlement data, payout data, and supporting files across different periods.

Common challenges include:

• High transaction volume across many orders, SKUs, and settlement periods
• Multiple report formats and changing file structures
• Fee deductions that are hard to trace line by line
• Refunds, returns, and partial adjustments that affect the final amount
• Differences between internal sales records and external settlement records
• Late or missing files that leave open items unresolved
• Excel-based matching that becomes hard to audit and reuse

When reconciliation is done manually, the same setup is often rebuilt each period. That slows down close work and makes exception review more difficult.

How Cointab handles Amazon reconciliation

Cointab is built around a simple Side A and Side B model.

• Side A contains your internal records, such as sales reports, ERP exports, order data, or books
• Side B contains Amazon records, such as settlement reports, payout records, fee files, refund data, or related reports

You can use a popular reconciliation when the Amazon report structure is standard, or create a custom reconciliation if your workflow needs a specific setup.

The usual process is straightforward:

1. Upload the required files for Side A and Side B
2. Map key fields such as date, amount, and identifiers
3. Optionally add supporting data for lookup, enrichment, or calculation
4. Optionally create derived columns with AI-generated Excel-style formulas
5. Run reconciliation manually or on a schedule
6. Review the report dashboard
7. Download the Excel output when the reconciliation is complete

This makes the process repeatable instead of rebuilding the same workbook logic every month.

What Amazon records can be compared

Cointab can help finance teams reconcile different Amazon-related records depending on the workflow.

Typical comparisons include:

• Internal sales report vs Amazon settlement report
• Internal order records vs payout or disbursement records
• Books or ERP exports vs Amazon-related external records
• Order-level records vs fee and deduction lines
• Sales, refund, and return data vs settlement output

Common identifiers may include order ID, transaction ID, settlement ID, payment reference, SKU, or other business references used in the files.

How matching works

Cointab uses structured reconciliation logic to compare records on both sides.

The engine supports scenarios such as:

• One-to-one matching
• One-to-many and many-to-one matching
• Many-to-many grouping
• Net-to-net comparison
• Partial matching
• Contra-style matching where relevant

It also supports different comparison methods such as equals, contains, similar, equals subset, and contains subset.

This is useful in Amazon workflows where one settlement line may relate to multiple internal rows, or where identifiers are present but not always in the same format.

After structured matching, remaining open items can be analyzed further using AI. If the evidence is not strong enough, the record should remain unmatched rather than being weakly forced into a match.

What the reconciliation report shows

After a run completes, Cointab presents the reconciliation in clear transaction-level views. Finance teams can review the report by status and drill into exceptions.

Fully matched

Fully matched records are transactions where the required identifiers and amounts match according to the reconciliation rules.

Partially matched

Partially matched records are related transactions where the identifiers match, but the amounts differ. This is useful for spotting short payments, extra deductions, rounding issues, or settlement differences that need review.

Unmatched

Unmatched records are present on one side but not found on the other. In Amazon reconciliation, that can indicate a missing settlement line, an open internal record, or a file that still needs to be uploaded.

Skipped

Skipped records are rows that were not included in reconciliation because they were incomplete, invalid, duplicated, or excluded by rule. These are visible in the report so the team understands what was ignored and why.

Why finance teams use this workflow

Amazon reconciliation is not only about finding differences. It is about creating a controlled process that the finance team can reuse and trust.

Cointab helps teams:

• Reduce repetitive Excel work
• Reuse the same reconciliation setup for future periods
• Focus on exceptions instead of reviewing every row manually
• Separate matched, partially matched, unmatched, and skipped records clearly
• Add supporting files for enrichment or lookups when needed
• Create derived columns for normalized amounts, cleaned identifiers, or rule-based calculations
• Review and download audit-ready Excel reports
• Keep reconciliation history available on the dashboard
• Work in a shared team workspace with roles and access control

For recurring Amazon workflows, this makes reconciliation more consistent across periods and users.

Automation for recurring Amazon reconciliation

If your Amazon reports arrive on a regular schedule, Cointab can support recurring workflows through email, SFTP, or API-based data flow.

That means you can set up the reconciliation once and then run it repeatedly with less manual effort. The platform can also refresh a report if a missed file is uploaded later, which is useful when marketplace files arrive after the main close cycle.

Automated reconciliation is especially helpful for teams that manage frequent settlement cycles, multiple report sources, or monthly close responsibilities.

Common Amazon reconciliation questions finance teams ask

Finance teams often want to know whether the difference is caused by a missing file, a late settlement, a refund, a fee, a return, or a data formatting issue. Cointab helps isolate these items so the team can investigate only the open transactions that matter.

The platform is also useful when different team members need a consistent process. Instead of each person building their own spreadsheet logic, the reconciliation setup stays reusable in one workspace.

When a custom setup is better

A popular reconciliation works well when Amazon report formats are standard. A custom reconciliation is a better fit when your internal records need to be combined with multiple supporting files, derived columns, or business-specific matching rules.

That is useful for workflows such as:

• Internal sales report vs Amazon settlement files
• Books vs marketplace settlement
• Order-level data vs fee and deduction reports
• Settlement reconciliation across multiple internal sources

In each case, the goal is the same: compare Side A with Side B, identify exceptions clearly, and keep the output ready for review and audit.
