How to deal with mass sending of e-invoices for several centers and programs?
Short answer
The law does not prevent a company from collecting e-invoices from several centers or programs, checking them and submitting them to the e-invoicing delivery-service provider in batches. However, this does not mean that every software or provider already supports marking and sending multiple documents in one operation. Before deployment, you should verify supported inputs, validation, batch limits, duplicate submission protection, and how separate statuses and errors are returned for each invoice.
Contracted by an accountant
Through her own accounting software provided by the postman.
Recommended practice
It catches errors from centers before the invoice leaves the company.
A commonly supported feature
Batch processing of several invoices at once through one provider.
Technical condition
Invoices from centers must be transferable to the correct format.
Conclusion
The model of central contracting the postman through your accounting software, with subsequent control and mass sending of invoices from several centers is a workable and recommended way to reduce the risk of errors.
