AI bookkeeping for e-commerce companies.
Orders move through your shop. Money moves through Stripe, Adyen and PayPal. Goods move through dropshippers, warehouses and carriers. Cortena keeps the books current: supplier and freight invoices coded, payouts reconciled, COGS and channel costs on the right product and cost centre.
For D2C and online retailers · works with Stripe, Adyen, PayPal and your ledger
Your shop is live. Your books are still catching up.
In most SMBs the storefront, the payment providers and the warehouse each tell a different story. Finance is left to stitch them into one ledger.
A normal week brings dropship supplier invoices after the parcel already shipped, 3PL and carrier bills that do not match order IDs one-to-one, Meta and Google invoices that should hit products or channels, and payouts that land net of fees, chargebacks and reserves. Spreadsheets hold until volume grows. Then margin becomes a guess.
| Supplier | Type | Account | Cost centre | Amount |
|---|---|---|---|---|
| Shenzhen Apex Trading Co. | Dropship | 5400 | SKU-118 | 4.820,00 |
| DHL Parcel Germany GmbH | Freight | 5800 | FUL-01 | 1.246,40 |
| Meta Platforms Ireland Ltd. | Ads | 6600 | CH-META | 3.190,00 |
| Stripe Technology Europe | Fees | 6855 | PAY-01 | 612,80 |
Four moving parts. One set of books.
Cortena is built for the finance work around the shop, not for replacing your OMS or WMS.
Suppliers invoice after the order ships
Dropship partners, print-on-demand vendors and wholesalers send invoices days after fulfilment. Each one still needs the right GL, VAT and product or channel allocation.
Fulfilment and freight are their own invoice stream
3PL fees, pick-and-pack, DHL and returns credit notes arrive on their own cadence. Cortena captures and codes them so fulfilment cost is visible per period, not buried in a lump sum.
Payouts are not gross sales
Stripe, Adyen, PayPal, Klarna and card schemes pay out net of fees, chargebacks and rolling reserves. Those movements have to land correctly in the bank and in the ledger.
Marketing and goods must meet on the same product
Ads, affiliates, packaging and goods cost only become real margin when they share cost centres and cost carriers with the orders they support. Your controllers set that logic once.
Connected to the tools e-commerce already runs.
Cortena sits next to your shop and payment providers. It does not ask you to rip them out. Supplier invoices, agency bills and bank payouts flow into booking-ready entries for DATEV, Exact Online or Twinfield.

Payouts, fees and chargebacks show up on the bank statement. Cortena matches them to open items and keeps cash current, so GMV in the shop and cash in the bank stop arguing.

Straight answers on dropshipping, payouts and COGS.
Yes. Dropship partners, wholesalers and fulfilment providers send invoices like any other supplier. Cortena captures them, codes each line to your GL, cost centre and VAT rules, and queues them for approval. Late invoices after shipment are normal in e-commerce, and they still get the same treatment.
Those providers collect from customers and pay out to your bank, usually net of fees. Cortena codes related fee invoices and reconciles the payout lines on your bank statement against open items, so cash and ledger stay aligned. You keep Stripe, Adyen, PayPal, Klarna or Mollie as they are.
Yes, by the keys your controllers define. Meta, Google and affiliate invoices can land on cost centres and cost carriers that match how you read channel and product margin. Cortena applies that logic line by line. Full controlling dashboards are on the roadmap and labeled Soon where they appear elsewhere on the site.
No. Cortena is the AI operator for accounts payable and receivables around your shop. Orders, stock and shipping labels stay in the tools you already use. Finance gets booking-ready payables, payout reconciliation and a clean handoff to DATEV, Exact Online or Twinfield.
Send credit notes to the same inbox as invoices. Cortena captures them with the supplier case so returns and refunds are visible next to the original bill, coded and ready for approval instead of lost in a shared mailbox.
DATEV via the official Rechnungsdatenservice 1.0, Exact Online and Twinfield. Batches arrive booking-ready with the source document attached. Your accountant keeps their tool and their process.
