Do automated invoice processing yourself or have it done?
Much of what's involved in automating invoice processing can be built in-house — the question is whether it pays off. When in-house effort makes sense, where the boundary lies, and which path is the most expensive.
Building automated invoice processing yourself pays off when the project stays small, someone in the business has time for it, and no one depends on it running on a specific day. As soon as other systems need to interact or someone is liable if it fails, external implementation is usually cheaper — the most expensive path is the half-finished one.
01 — In-house effort
Build yourself or have it built?
- Building yourself makes sense when someone in the business has the time and interest, the project stays small, and no one depends on it being live by a specific date.
- Ready-made platforms get you to a first result quickly, but hit limits where custom processes, custom data, or integrations with existing systems come into play.
- Having it done pays off as soon as automated invoice processing needs to talk to other systems, as soon as someone is liable if it doesn't work, or as soon as internal effort becomes more expensive than external implementation.
- The most expensive path is the halfway one: built in-house for months on the side, then abandoned and rebuilt externally. If you decide on in-house effort, set a time budget and an abort point.
- Hybrid approach: concept and setup external, maintenance internal. This is often the most economical path for automated invoice processing — provided the handover is documented.
02 — Requirements
What you need for automated invoice processing
- A clearly defined trigger. Not “we should do something with AI,” but a process that demonstrably costs time or orders today.
- Existing content or data. Automated invoice processing works with what's there. The more complete the starting point, the shorter the setup.
- Access to the systems involved. Whoever manages the credentials needs to be involved from the start — this is, in our experience, the most common cause of delays.
- One decision-making contact person. One, not three.
- Willingness to refine after launch. The first weeks in real operation show what was missing in the concept. That's normal and accounted for.
03 — Calculation
How to calculate it
Four numbers are enough: How often does the process occur? How long does it take? What does an hour cost internally? And what does the solution cost — one-time plus operation over three years?
An example: A process that occurs twice a week and takes 40 minutes each time ties up around 69 hours per year. At an internal hourly rate of 45 euros, that's roughly 3,100 euros per year locked in there. If a solution reduces this effort by two-thirds, it often pays for itself — depending on the actual quote — within one to two years. We'll give you the exact figure for your case after the initial meeting.
This calculation is deliberately conservative: it only accounts for the time saved, not the errors avoided or the orders that come through due to faster response. In practice, the benefit is usually higher — but you shouldn't count on it before you've measured it.
04 — Questions
Frequently asked questions
Can we set up multiple approval levels?
Yes, tiered by amount — smaller sums go through automatically, larger ones require one or more approvals, depending on how you handle it internally.
What happens with an unrecognized invoice?
It lands in a review queue. Nothing is guessed and nothing gets lost. Over time, the queue gets shorter because recurring vendors are reliably recognized.
What if an invoice arrives twice?
The system detects duplicates based on invoice number, amount, and sender, and flags them instead of posting them twice — a common, costly error in manual entry.
What about invoices in foreign currencies?
They are recognized and posted using the stored exchange rate. If needed, you can set a fixed reference date rate or use the daily rate at invoice receipt.
Is this audit-proof?
The filing system meets requirements for immutability, traceability, and retrievability. Original document, extracted data, corrections, and approvals are logged with timestamps. The retention period in Austria is generally seven years.
Will our tax advisor work with this?
Usually yes — standard accounting firm systems accept structured data. We clarify this upfront directly with your firm, because their requirements determine the interface.
What about mandatory e-invoicing?
Structured electronic invoices are becoming mandatory across Europe in stages, with different deadlines by country. Processing that understands formats like ZUGFeRD and XRechnung from the start saves you from later conversion.
05 — Decision
How to move forward
The most affordable next step is a conversation, not a quote. Twenty minutes is usually enough to clarify whether a project makes sense, what scope it involves, and whether we're the right fit.
If we're not, we'll say so. An honest no costs less than a project you abandon after three months — for both sides.

A twenty-minute conversation is usually enough to clarify whether a project makes sense. If not, we'll say so — that's cheaper for both sides than an offer nobody needs.
