Marketplace Reconciliation Automation with Cointab

Marketplace reconciliation is the process of matching internal records with marketplace reports so finance teams can confirm what was sold, what was settled, what was deducted, and what still needs review. For teams working across multiple marketplaces, payment gateways, bank statements, returns, fees, and payouts, this process can become repetitive and difficult to manage in Excel.

Cointab helps finance teams streamline marketplace reconciliation with a structured workflow. Users upload the relevant files, map the required fields, run reconciliation, review matched and unmatched transactions, and download audit-ready Excel reports. The same setup can then be reused for future periods.

What marketplace reconciliation usually covers

Marketplace reconciliation is broader than simply comparing sales and settlement totals. In most finance workflows, it involves matching several connected reports and reviewing differences across them.

Common reconciliation scenarios include:

• Marketplace sales vs settlement reports
• Marketplace orders vs payment records
• Sales vs returns, refunds, or cancellations
• Settlement reports vs bank receipts
• Gross sales vs deductions, fees, and commissions
• Internal books vs marketplace statements

For example, a finance team may upload marketplace order data on Side A and settlement or payout data on Side B. Cointab then matches transactions using identifiers such as order ID, settlement ID, transaction ID, AWB number, invoice number, or other business references.

Why marketplace reconciliation becomes difficult

As transaction volume grows, marketplace reconciliation tends to become slower and more error-prone. Many teams still rely on spreadsheet formulas, VLOOKUPs, copy-paste checks, and manual file comparisons.

This creates a few common problems:

• Multiple reports need to be compared every period
• Deductions, returns, and fees may be spread across different files
• Identifiers may not appear in the same format on both sides
• Large files are harder to audit in spreadsheets
• Exceptions can remain open for too long
• Different team members may prepare reports in different ways
• Reconciliation logic has to be repeated again and again

Cointab addresses these issues by replacing ad hoc spreadsheet work with a reusable reconciliation workflow.

How Cointab supports marketplace reconciliation

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

• Side A contains the records the business expects to be correct, such as internal sales, order, ledger, or ERP data.
• Side B contains external records received from marketplaces, payment providers, banks, or other partners.

This makes it easier for finance teams to reconcile marketplace data in a controlled and transparent way.

1. Use a popular reconciliation or create a custom workflow

For standard marketplace report structures, Cointab supports popular reconciliations. These are pre-built templates that already define file formats, matching logic, and data preparation rules.

For business-specific workflows, teams can create custom reconciliations. This is useful when a company wants to compare internal sales data against multiple marketplace settlements, payment sources, or supporting reports.

2. Upload files and map the required fields

Users can upload CSV, XLS, or XLSX files and map the important columns once.

Typical fields include:

• Header row
• Date column
• Amount column
• Reference or identifier column

Marketplace teams often use identifiers such as order ID, transaction ID, invoice number, settlement ID, payment reference, or AWB number.

3. Add supporting data when needed

Not every file has to be reconciled directly. Cointab also supports supporting data for enrichment and preparation before reconciliation.

This can help teams:

• Add missing order details
• Merge datasets before matching
• Look up fee or tax information
• Combine sales and return data
• Add internal mapping data to external reports

4. Create derived columns with AI support

If a report needs a calculated field before matching, users can create derived columns. Cointab's AI can help generate Excel-style formulas from plain-language instructions.

Examples include:

• Clean order ID
• Net amount
• Refund amount as negative
• Normalized transaction ID
• Amount after fee
• Combined reference field

This is useful when marketplace data needs to be transformed before reconciliation begins.

How the reconciliation engine compares marketplace data

Once the files are ready, Cointab applies structured matching logic. The engine can handle multiple reconciliation patterns, including:

• One-to-one matching
• One-to-many matching
• Many-to-one matching
• Many-to-many matching
• Net-to-net matching
• Contra matching
• Partial matching

It also supports comparison logic such as equals, contains, and similar matching where appropriate.

This matters in marketplace reconciliation because a single order may appear across several records, or several records may need to be grouped before they can be compared against a settlement line.

What finance teams see after reconciliation

After a run is completed, users can review the report dashboard and focus on the exceptions instead of manually checking every row.

Cointab separates transactions into clear categories:

• Fully matched: identifiers and amounts align according to the reconciliation logic
• Partially matched: records are related, but the amounts do not fully match
• Unmatched: records appear on one side but not the other
• Skipped: records were excluded because they were incomplete, invalid, duplicated, or otherwise unusable

This structure helps teams identify where the issue is coming from. For example, a partial match may point to a fee, deduction, refund, or rounding difference, while an unmatched record may indicate a missing payout or an incomplete file.

How AI supports unresolved marketplace exceptions

After structured matching is complete, Cointab can use AI to analyze the remaining open items. AI is not used to blindly force matches. Instead, it helps finance teams review difficult cases more efficiently.

AI can help with:

• Unstructured or inconsistent references
• Slightly different transaction descriptions
• Missing or partial identifiers
• Complex grouping scenarios
• Reason analysis for open items
• Suggested next actions for unresolved differences

If the evidence is not strong enough, the transaction remains unmatched so the review stays conservative and audit-friendly.

Reusable workflows for recurring marketplace runs

One of the main benefits of marketplace reconciliation automation is reuse. Once a reconciliation is configured, teams do not need to build it again every month or every period.

The same workflow can be reused for:

• Monthly reconciliation
• Quarterly reconciliation
• Yearly reconciliation
• Lifetime or all-time reconciliation
• Custom settlement periods

This helps reduce repeat setup work and makes the process more consistent across finance teams.

Automation for recurring data flow

For teams that reconcile marketplace data on a regular basis, Cointab can automate input and output flows through email, SFTP, or API.

That means a marketplace report can be received automatically, validated, loaded into the correct workflow, and reconciled on a schedule. After the run is complete, output can be delivered back to downstream systems such as accounting, ERP, BI, analytics, or internal operations tools.

This is useful when marketplace finance is part of a daily or weekly operating rhythm rather than a one-time monthly task.

Audit-ready reporting and team collaboration

Cointab keeps reconciliation results available in the dashboard for future reference. Finance teams can review past runs, see who ran the workflow, and download Excel reconciliation reports when needed.

The team workspace also supports collaboration across users with shared visibility, roles, permissions, and audit logs. That makes it easier for finance, accounting, and operations teams to work from the same reconciliation record instead of passing spreadsheets around.

When marketplace reconciliation is a good fit for Cointab

Cointab is a strong fit when a business needs to reconcile:

• Internal sales data against marketplace settlements
• Orders against payments or payouts
• Marketplace deductions, fees, and commissions
• Returns, refunds, and cancellations against expected records
• Books against external marketplace statements

It is also useful when teams want a single platform for recurring reconciliation rather than a new spreadsheet process for every marketplace or reporting period.

Marketplace reconciliation that finance teams can reuse

Marketplace reconciliation should give finance teams clear visibility into what matched, what did not match, and what needs follow-up. With a structured workflow, reusable setup, AI-assisted review, and downloadable reports, Cointab helps teams manage marketplace finance with more control and less manual spreadsheet work.
