Where e-commerce accounting goes wrong

Sales data alone is not enough. For reliable bookkeeping in Germany, data from your online shop, marketplaces, payment providers, inventory and receipts must be incorporated into a consistent monthly accounting routine.

Multiple systems, but no reliable BWA.

Online shop, marketplace, payment and receipt data is held separately. At month-end, there is no clear view of the business as a whole.

Cost of goods sold and inventory remain unclear.

If COGS, inventory and purchasing data are not plausible, growth can appear stronger than it is economically.

Discounts and returns distort margins.

Klarna, PayPal, Stripe, marketplace fees and returns must be allocated correctly. Otherwise, your contribution margin remains unclear.

Software, a standard tax firm or SPIELMANN?

E-commerce bookkeeping requires more than exported data. What matters is who can properly integrate your online shop, marketplaces, payment providers, inventory and DATEV.

Software

Provides exports and dashboards, but does not assess the tax treatment or continuously reconcile data quality.

Standard tax firm

Can handle bookkeeping, but often lacks sufficient expertise in setting up marketplace data, payment fees, inventory and e-commerce management accounts (BWA).

SPIELMANN

Combines expertise in online shop, marketplace and payment data with DATEV, our own e-commerce management accounts (BWA) and a monthly routine you can rely on.
