Accounting in online retail is highly complex. In addition to the mass of transactions, there are also many tax pitfalls, especially with regard to foreign shipments. We therefore advise online retailers to have their bookkeeping prepared by a tax consultant who specializes in online trading. Online retailers who prepare their own bookkeeping can become our customers if they have their own bookkeeping department. In this case, we will be happy to arrange an appointment with our enterprise team. Otherwise, we will be happy to recommend a tax consultant in your area. We have access to our network of over 900 tax advisors.

We follow the pay-as-you-go principle. With us, you only ever pay for the number of transactions that have actually occurred. Instead, we bill you retrospectively in the following month based on the transactions used in the previous month. The package changes to the right package for you every month. If you use more, you automatically switch to the next higher package. If you use fewer transactions, you also switch to the correspondingly smaller package, fully automatically.

In principle, the online retailer is the contractor with AccountOne. Some tax firms assume the costs decentrally for their clients and then charge them on.

Multi-client access is available for tax consultants. Tax advisors can use this to manage all their connected clients and administer their employees via user and rights management. This access is free of charge. 

No, the retrospective billing method invoices after the end of the month on the basis of the transactions actually used.

No one wants to start with software only to discover in the course of processing that their request can only be fulfilled with additional services for which a fee is charged.

Special service

Retroactive data

So that the past is also perfect.

RW Exports for accounting

Not everything always runs smoothly. We know this and therefore also provide the data for accounting for periods that have already passed. 

Accounting exports can already be provided from 2017. Always taking into account the applicable legal regulations. 

Billing is based on the number of transactions at the nominal monthly rate.
