Basware works 24 hours every weekday (24/5), except on public and bank holidays. The scanned invoice needs human manual work; hence scanning is only done on weekdays.
The local postal service will deliver paper mail to the scanning facility in the morning. Mail is sorted by PO Boxes, envelopes are opened and papers are sorted removing paper clips for example. Then the papers are scanned and sent to validation (OCR-process). This is computer-based and needs humans to check captured fields suggested by the traffic lights.
The scanned invoice's delivery time once received at Basware and delivered to the recipient's system, is around +24 hrs. A good guideline is that there needs to be one business day between received and delivered.
Friday morning - Paper mail is delivered to local scanning facility - Invoices are entered to the e-invoicing flow Saturday (last Friday shift working)
Saturday - Only critical production support working
Sunday - Only critical production support working
Monday morning - Paper mail is delivered to the local scanning facility - Invoices are entered into the e-invoicing flow on Tuesday
** If the supplier will send the invoice via email as a PDF file to email scanning (@bscs.basware.com) during the weekend, the validation starts whenever the first shift arrives to work on Monday morning. If the email is received late Friday, the delivery is on Tuesday.
Therefore, it is likely that there will be no scanned invoices arriving on Monday.
