Accounting as a webshop owner

Do it yourself or outsource to a bookkeeper for webshops?

Doing your bookkeeping yourself is fine if you have basic knowledge and your webshop is still manageable. Modern packages automate bank feeds, purchasing and invoicing, so you can quickly prepare VAT returns and reports. As your order volume grows, you sell in multiple countries or you handle returns and different VAT rates, the risk of errors rises and your efficiency drops.

Outsourcing to a bookkeeper with e-commerce experience saves time and prevents back taxes. A hybrid approach often works best: you process day-to-day items via a connected package, Profinancials checks, files your returns and proactively advises on optimizations such as revenue groups, inventory valuation and margin insight per channel.

What are the requirements for your webshop bookkeeping?

As a webshop owner your bookkeeping must be complete, accurate and auditable. This means, among other things:

• Retention - Keep your records for at least 7 years, digitally or physically. Think of sales invoices, POS systems, payment reports, purchasing, contracts and bank statements.

• Invoice numbering - Use a continuous, unique sequence per channel or centrally with clear references to prevent duplicates.

• Revenue and VAT - Record revenue by country, rate and channel. Split shipping costs, discounts, gift cards and payment fees.

• Returns and credit invoices - Process returns with correct VAT crediting and payment methods.

• Purchasing and inventory - Record purchase invoices, customs clearance costs and shipping materials. Ensure consistent inventory valuation.

• Digitization - Use scan-and-recognize (OCR), bank feeds and payment channel exports for reconciled, audit-proof books.

If you sell to consumers in other EU countries, take into account the OSS scheme and local VAT rates. A tightly organized bookkeeping prevents corrections afterwards and gives real-time insight into margin, return ratio and cash flow. Want to better plan tax peaks?

VAT for EU sales and the OSS scheme

If you sell cross-border to consumers within the EU, a combined threshold of €10,000 per year applies. Above this amount you charge the VAT of the customer’s country. With the One Stop Shop you file centrally each quarter, after which the tax authority forwards the VAT to EU countries. Therefore record revenue by country and VAT rate and align your webshop and accounting package accordingly. Profinancials sets up your reports, monitors thresholds and handles your OSS return.

The right accounting package for your webshop

Choose a package that grows with your webshop. Look for these features:

• Seamless integrations - Shopify, WooCommerce, Magento and marketplaces.

• Payment platforms - iDEAL, PayPal, Klarna, Mollie, Stripe with automatic reconciliation.

• VAT and OSS - Support for multiple rates, countries and OSS reports.

• Inventory and cost prices - Insight into margin per product and channel.

• Bank feed and scan-and-recognize - Less manual work, fewer errors.

We advise on and implement the package that fits your stage and channels. See also How we organize your webshop bookkeeping.

Connect your webshop to your accounting

A good integration prevents manual work and mispostings. Synchronize at least orders, VAT rates, products and payment statuses. Post payouts from payment providers to revenue groups per country and rate, including transaction fees and refunds. Set up return flows so that credit notes and VAT are handled correctly and your inventory stays accurate.

• Practical tips - Create revenue groups per country and rate, set clear rules for shipping costs and discounts, and archive periodic payout reports from payment platforms.

• Fallback - No technical integration possible? Periodically import CSV exports with a clear column mapping.

Frequently asked questions

How should I keep my webshop bookkeeping?

Work digitally and in a structured way. Use an accounting package with a bank feed and scan-and-recognize, connect your webshop and payment platforms, and record revenue by country and VAT rate. Process returns via credit notes, number invoices consecutively and keep everything for 7 years. Schedule a fixed monthly closing to check VAT and margin.

Can I do my own bookkeeping as a sole proprietor?

Yes, with a suitable package and basic knowledge you can go a long way. Automate bank, invoices and integrations and keep a monthly rhythm. If your situation becomes complex due to EU sales, multiple channels or staff, bring in a bookkeeper. Profinancials can review, file the returns and optimize your bookkeeping. For solo webshop owners, our Accounting office for self-employed webshop owners is a fitting choice.

What are the costs of a bookkeeper for a webshop?

Costs depend on order volume, number of channels, EU sales and desired support. Profinancials works with fixed monthly fees based on your situation, including bookkeeping and tax returns. This way you know in advance what to expect and you don’t pay for unnecessary hours. Looking for regional support? See Accounting firm for webshops in Eindhoven.

How much are you allowed to earn on the side with a webshop?

There is no fixed limit. Income from your webshop is taxed as business profits or income from other activities. If you sell structurally with the intention of making a profit, registration and VAT administration are required. Track hours, revenue and costs, and avoid surprises by seeking advice in time.
