Take control of your company's costs
Flux uses data from KSeF and OCR to turn cost invoices into real control over spending. It shows who owns each cost, what it is for, whether it fits the budget, how it affects results and where prices are creeping up.
Seeing an invoice is not the same as controlling it
KSeF and OCR read the data from invoices, but they don't show the business context. You don't know who owns a cost, what it relates to, whether it was planned, whether it fits the budget and whether its price has gone up.
Costs have no owner
It is not always clear who should describe, approve and justify a given expense.
Budgets are controlled after the fact
The company sees overruns only once the cost has already been incurred.
Business context is missing
An invoice shows the amount and the vendor, but not the project, cost center, purchase purpose or impact on results.
Price increases slip by in daily work
Without comparing historical prices it is hard to notice quickly that the same product or service keeps costing more.
From a KSeF cost invoice to full cost control
Flux covers the whole cost-invoice flow — from KSeF intake and automation, through approval, to analysing the impact on company costs.
Pulls data from the invoice
Flux uses KSeF and OCR to gather the data needed for further work with a cost.
Gives the cost context
An expense can be assigned to a person, cost center, project, category, budget or a specific area of the company.
Runs the approval
The cost reaches the right person, who can approve it, reject it or add a description.
Shows the impact on the company
Flux shows budget usage, price increases, cost structure and the impact of spending on results.
Flux runs in production at Oreco
Oreco is a food distributor for hospitality and retail - over PLN 150M in revenue and more than a thousand purchase invoices a month from several hundred vendors. Flux wasn't designed in a vacuum: it was built inside Oreco to get a grip on costs that are invisible in the ERP and in KSeF alone. Since February 2026 it has been running there in production - connected to KSeF and Comarch ERP XL.
Over 1,000 invoices a month, 100% straight from KSeF
Every cost invoice reaches Flux automatically — no manual entry, no scanning, no paper. And the number grows month over month.
PLN 55M of purchases from 410 vendors under control
From day one Flux covered the entire purchase-cost stream at Oreco - from raw materials, through fuel, to services.
No invoice gets lost in an inbox
100% of invoices go through the approval flow. Routine ones are approved by rules - with no people involved. Where a human decision is needed, it is made within a day.
“We weren't looking for yet another system - our ERP is connected to KSeF. But only Flux showed us costs the way we look at them operationally: what we buy, from whom, and whether anyone even approved it. At over a thousand invoices a month, that makes a difference.”

Frequently asked questions
What's worth knowing before the first call
Your ERP and KSeF see invoices — Flux sees costs. It shows what's not on the invoice: who owns the expense, whether it was planned, whether it fits the budget and whether the vendor's price is rising. The ERP stays the source of data and you change nothing in it — Flux is a control layer on top.
