Marketplace Accounting: Turn Monthly Statements into Google Sheets Automatically

If you sell on marketplaces (Amazon, Etsy, eBay, Walmart Marketplace, etc.), you already know the pain: every month you download statements, copy numbers into a spreadsheet, reconcile fees, and try to make sense of payouts vs. sales. It’s repetitive, error-prone, and it steals time from the work that actually grows the business.

Img2Sheet helps you automate that workflow by extracting structured data from your marketplace statements using AI (not just OCR) and inserting it into Google Sheets exactly in the format you define.

The common problem with marketplace statements

Marketplace statements are not designed for bookkeeping—they’re designed for marketplaces.

That usually means:

  • Different layouts depending on the marketplace (and sometimes even month-to-month)
  • Totals spread across multiple pages
  • Fee breakdowns with inconsistent wording
  • Payout summaries mixed with refunds, chargebacks, shipping, taxes, and adjustments
  • Data entry that turns into a monthly ritual (and a monthly headache)

Even if you’re disciplined, manual entry leads to:

  • missing fees
  • swapped numbers
  • wrong dates
  • inconsistent categories
  • reconciliation issues later

What “AI extraction” changes (vs. traditional OCR)

Traditional OCR is mostly: “read text from an image/PDF.”
But marketplace accounting needs more than reading text—you need understanding and structuring:

  • Identify which number is payout vs gross sales vs fees
  • Map values into consistent columns even when the statement format changes
  • Pull specific fields reliably (dates, statement period, marketplace name, currency, settlement IDs, etc.)
  • Extract line items or grouped totals based on your accounting needs

Img2Sheet uses AI to extract meaningful fields based on your instructions, then inserts them into your spreadsheet in a clean, consistent format.

How Img2Sheet works for marketplace statements

Instead of hoping the output looks right, you define the structure first.

1) Create your “Statement Structure”

You create columns with:

  • Label (what the column is called in Google Sheets)
  • Type (text or number)
  • Prompt (what data to extract — written in plain language)

This becomes your “template” for monthly statement imports.

2) Upload your monthly statement

You upload the statement image/PDF.

3) Get data inserted into Google Sheets exactly as your structure

The extracted values are inserted in the same order and format as your defined structure—so your sheet stays consistent month after month.

Example structure for marketplace monthly statements

Here’s a practical starter structure many sellers use:

Statement Summary (per month)

  • Marketplace (text) — “Marketplace/platform name (Amazon, Etsy, eBay, etc.)”
  • Store Name (text) — “Store/account name on the statement”
  • Statement Period Start (text) — “Start date of the statement period”
  • Statement Period End (text) — “End date of the statement period”
  • Currency (text) — “Currency code/symbol used (USD, EUR, GBP…)”
  • Gross Sales (number) — “Total sales before fees/refunds”
  • Refunds (number) — “Total refunds/returns”
  • Marketplace Fees (number) — “All marketplace fees total (commissions, referral, etc.)”
  • Shipping Charges (number) — “Shipping collected or charged (if present)”
  • Taxes (number) — “Taxes collected/paid shown on statement”
  • Adjustments (number) — “Any adjustments/chargebacks/other”
  • Net Payout (number) — “Final payout amount (settlement/disbursement)”
  • Payout Date (text) — “Date payout was issued”

Optional: Settlement identifiers

  • Settlement ID / Statement ID (text) — “Unique settlement ID if present”
  • Bank Reference (text) — “Bank transfer reference if shown”

Once this exists, you can import every month into the same sheet and instantly get a clean dataset ready for reporting.

Best practices to get clean, consistent accounting data

  • Be explicit in prompts:
    Instead of “fees”, write “total marketplace fees (commissions + service fees + referral fees).”
  • Keep one structure per marketplace (if formats differ a lot):
    You can create “Amazon Monthly Summary”, “Etsy Monthly Summary”, etc.
  • Use number type for money columns so totals and charts work immediately in Sheets.
  • Add a “Notes” column (text) for edge cases (rare adjustments, special one-time credits).

Security and privacy: no files stored

Your statements can contain sensitive financial data. That’s why:

  • No file links are shared
  • All uploaded files are removed immediately after extraction

You get the structured results in your Google Sheet—without leaving documents sitting around.

What you can do once the data is in Google Sheets

When your monthly statements land in a consistent table, you can:

  • Track profit trends by month
  • Compare marketplaces side-by-side
  • Build dashboards (revenue, fees %, refunds, net payout)
  • Reconcile payouts vs. bank deposits faster
  • Share clean numbers with your accountant/bookkeeper

Next step

If you’re tired of spending hours every month on marketplace statements, start by creating one structure (like the example above), upload a recent statement, and let your Google Sheet update itself the same way every time.
