You enter invoices and packing slips by hand

In short

Do you retype invoices and packing slips by hand? Software can read them and prepare the data in your accounting or stock system. Anything that doesn't match or is out of the ordinary goes to an employee. First check what your accounting package can already do.

Have documents read automatically: exceptions go to an employee

Invoices and packing slips look different for every supplier. That is why someone often retypes them: the supplier, the date, the items, the quantities and the amounts. That work comes back every day. And when you retype, things sometimes go wrong.

Do you recognise any of these situations?

  • Packing slips sit in a pile until someone has time to enter them.
  • You check by hand whether the invoice matches what was delivered.
  • Purchase invoices arrive as PDFs and are retyped line by line.
  • You only notice a difference in quantities when the stock doesn't add up.

How can you process packing slips without retyping?

Packing slips belong to goods receipt and stock, and accounting packages usually don't read them. This is where custom software can help. It can read the packing slip with OCR and AI, compare it with the purchase order and the invoice, and prepare the quantities in your stock system. Through an accounting integration the invoice goes to your accounts.

Does something not match, such as eight boxes delivered and ten invoiced? Then the document goes to an employee. They decide what happens. That way a person keeps control of the exceptions.

Does your accounting package already read the invoices?

Look at your package first. Some packages read purchase invoices themselves, such as SnelStart (not in every subscription) and Moneybird. Do check the result yourself. An e-invoice already contains the data as codes and doesn't need to be read. A PDF is not an e-invoice and does need to be read. You can read more about this in Reading invoices automatically.

When is it not needed?

Is it a few invoices a week, and does your package read them well? Then that is enough. Custom software suits large numbers of documents, or cases where you want to compare packing slip, order and invoice side by side.

How I help you with this

The first conversation is free. After that, in a business analysis, I look at which documents come in, how many there are and what your package can already do. Based on that you get a proposal with a fixed price, so you know in advance where you stand.

If custom software makes sense, I build software that reads invoices and packing slips and puts them into your systems. Read more under automation. What that costs depends on the type of documents, how many there are and which systems it has to work with. Hosting and maintenance are agreed per month in consultation.

Frequently asked questions

Do I still need to check documents that have been read in?

Yes. Reading documents is not error-free. That is why I set it up so that doubtful cases and exceptions end up with an employee.

Does it also work with paper packing slips?

Yes, if you scan or photograph them. The better the scan, the better the software can read the text.

Do I need a different accounting package?

Usually not. I first look at what is possible with your current package. I don't receive any commission if you buy new software.
