Automating how invoices are issued and sent

Published 4 August 2026Updated 29 October 2026Qerify

You already have the data for the invoice. It is in the order, in the contract or in the timesheet. Even so, once a month someone sits down, retypes it into the invoicing software and then sends each invoice separately.

4 to 8 h/week
Implementation cost

Realistically you will recover from PLN 0 to PLN 0 a year

Here is the math: salary times the employer cost multiplier 1.2 divided by 173 hours a month gives the hourly rate. That rate times the hours in a year gives the cost of the process. From the recovery we take a band of 40% to 70%, because part of the time recovered on paper comes back as supervising the automation and handling exceptions. This is a deliberately conservative range, not a promise.

Where the hours go

Issuing a single invoice takes two or three minutes. The cost lies in everything around it: checking that the client's details have not changed, adding the right line item and VAT rate, pulling the number of hours from another file, sending it to the right address, then noting somewhere that the invoice has gone out. At fifty invoices a month that is a full day's work, usually squeezed into the end of the month, when time is shortest.

On top of that comes chasing payments. Someone compares the bank statement with the list of invoices and sends reminders. This is the part people forget when estimating what the process really costs.

What automation does

The invoice is generated automatically from data in your CRM or shop. The system keeps numbering continuous, applies the right VAT rates and sends the finished PDF straight to the client.

The other half is the payment side. A payment into your account can be matched to an invoice by the transfer reference and amount, and overdue invoices without a payment can generate a reminder on their own. A person gets a list of cases that need a decision instead of the whole list of invoices.

What it costs and when it pays back

Implementation usually falls between 2,000 and 6,000 PLN, the lower part of the platform's automation range, which goes up to 20,000 PLN. This process is cheaper than most because the input data is structured and invoicing software usually has a well-documented API.

Payback takes 3-5 months. If invoicing takes you 6 hours a week, our calculator shows the annual saving set against the implementation cost.

Frequently asked questions

Usually 2,000 to 6,000 PLN as a one-off. That is the lower part of the platform's automation range, which goes up to 20,000 PLN for more complex processes. The price rises when an invoice has to be built from several sources at once or when unusual billing is involved, such as a subscription with overage charges.

An automatically generated invoice has full legal force. The integration connects to your accounting software and stays compliant with regulations and the KSeF system.

You do not need to change your accounting software as long as it has an API or an import function. Separating the automation from a software change lets you assess ROI precisely.

It depends on the number of invoices. With one person spending six hours a week, we are talking about roughly 26 hours a month, of which automation realistically takes over 40% to 70%. The rest stays with a person: unusual line items, corrections and conversations with clients about payment.
