Bookkeeping for online stores and marketplaces

In online retail, money rarely comes directly from the customer. We integrate marketplace statements, payment services, and bank transactions so that every sale, every fee, and every refund is accounted for correctly.

Your industry

What sets your industry apart

An online retailer often has thousands of small sales per month but only a few incoming payments. Amazon, eBay, and other marketplaces pay out in batches and deduct fees, advertising costs, refunds, and reserves beforehand. If you only record the payout, you lose track of revenue and expenses. That’s why we post entries based on the marketplaces’ settlement reports.

Payment services like PayPal, Stripe, Klarna, or Mollie act as separate accounts between the customer and the bank. We manage them like bank accounts, reconcile balances, and assign fees, currency conversions, and chargebacks. At the end of the month, every balance must match what the service itself shows.

Returns are part of everyday business. Refunds to customers, returned merchandise, and credit memos must be matched to the corresponding sales. There are also shipping providers, packaging, and fulfillment services, which often send combined invoices.

If you sell to other EU countries or keep goods in warehouses abroad, you face VAT questions in other countries, such as the EU’s OSS procedure or registrations. The tax advisor assesses this. We give them the sales figures by country, exactly as the platforms report them. Marketplaces also report their sellers’ sales to the tax authorities themselves, which makes bookkeeping that matches these figures all the more important.

An online store also functions as a warehouse. Goods are often imported in large quantities, stored in your own warehouse, at fulfillment service providers, or at Amazon, and are not sold until months later. To ensure that large purchases do not skew the monthly report, we reconcile purchases and inventory with the figures from your inventory management system, if you use one. At the end of the year, your tax advisor will need an inventory count, including goods stored in third-party warehouses.

Attention to detail

What we pay attention to

  • Marketplaces: posting from settlement reports with sales, fees, and refunds
  • Payment services: PayPal, Stripe, and others as separate accounts, with balances reconciled
  • Returns: refunds and credits matched to sales
  • Shipping and fulfillment: combined invoices split up
  • EU sales: revenue by country prepared for the tax advisor
  • Purchases and imports: purchase prices, freight, and import duties fully recorded
  • Advertising costs: ads on platforms and search engines kept separate
  • Gift cards and small-amount invoices recorded correctly
  • Inventory: goods in your own and third-party warehouses reconciled with the inventory management system

Price

What it costs

Ongoing bookkeeping and payroll at a price on request. You’ll receive your quote after completing a short questionnaire. All prices are net, plus VAT.

Receipts

Which receipts we need

  • Settlement reports from Amazon, eBay, Etsy, Otto, and other marketplaces
  • Account statements from PayPal, Stripe, Klarna, and Mollie
  • Exports from Shopify, WooCommerce, Shopware, or JTL
  • Invoices from suppliers, shipping providers, and fulfillment partners
  • Reports from EU VAT tools, if you use any

You can download most reports as files and upload them to the client portal. For larger volumes, we’ll work with you to set up a fixed process so that the same reports are received every month.

Start

How we get started

To get started, we go through all your sales channels and payment services with you and determine which reports come in each month. We set up a separate account for each marketplace and each payment service. Your tax advisor posts the opening balances from the last financial statements; we reconcile the accounts with them. After that, you upload the reports by the 5th of the following month, and the report is ready in the client portal shortly afterward.

With your tax advisor

We post the entries; the tax advisor decides the tax treatment

We set up the chart of accounts, record ongoing business transactions, run payroll, and prepare wage tax returns. Every month, we reconcile the accounts and pass the figures on to your tax advisor.

You hire the tax advisor directly, with your own contract and billing arrangement. If you don’t have one yet, we can put you in touch with our partner tax advisor, with whom we work closely.

Decisions on tax treatment are the tax advisor’s responsibility. We post entries so that they’re ready for the tax advisor to work with immediately.

How we work with tax advisors

The tax advisor handles the following on your behalf

  • VAT on sales to other EU countries and filings under the OSS procedure
  • VAT registrations for warehouses abroad
  • Advance VAT returns
  • Inventory valuation and annual financial statements

Questions

Frequently asked questions

Do you post every single order?

No, with so many sales, that would be neither necessary nor cost-effective. We post entries based on the settlement reports from marketplaces and payment services, aggregated but complete with revenue, fees, and refunds.

We sell throughout the EU. What do you need?

The reports from the platforms showing revenue by country. The tax advisor determines how to handle VAT there; we provide them with the figures they need.

Do you use integrations with our store?

We handle data exports from common online store and inventory management systems. We’ll determine which interface makes sense for you during our initial consultation.

How quickly is the month closed out?

As soon as the reports are available, usually within the first few days of the following month. A good rule of thumb is to have receipts and reports ready by the 5th.

We’re still a small business. Is this worth it for us yet?

Often yes, because marketplace and payment reports take a lot of time even with just a few hundred orders a month. We price it individually on request; the quote depends on your sales channels and the number of reports.

What do you need if we import goods from China?

Supplier invoices, freight and customs statements, and payment receipts. We allocate all costs to the shipment so that the landed cost is right.
