How to calculate the ROI of digital invoicing for Belgian SMEs

What the ROI calculator does

A digital invoicing ROI calculator lets you compare the costs of your current paper‑based or spreadsheet process with the costs of an e‑invoicing solution. By entering your own figures – number of invoices, time spent per invoice, number of quotes, lost receipts, etc. – you can see whether the expected savings outweigh the subscription fee.

Key elements to include in your own calculation

• Invoice processing time – estimate minutes spent on each invoice today and the minutes you expect after automation.
• Quote preparation time – consider the time saved by using templates and digital approval workflows.
• Error correction costs – list typical mistakes (e.g., VAT errors) and the cost of correcting them.
• Cash‑flow impact – note how faster electronic delivery could shorten payment cycles.
• Lost documents – estimate the value of receipts or supporting documents that are currently misplaced.
• Accounting overhead – assess how much less time your accountant needs to spend on manual entry.

Simple worksheet example

Enter your own data and apply an hourly rate for your staff to translate time saved into monetary value.

How to interpret the result

• Positive net saving – when the total monthly saving exceeds the subscription cost of the invoicing software, the investment may be financially justified.
• Break‑even point – the month in which cumulative savings equal the total cost of implementation.
• Payback period – the number of months needed to recover the initial setup effort.

Practical steps to get started

1. Gather baseline data – track how long it takes to create, send, and file an invoice and a quote for a typical week.
2. Identify error sources – list common mistakes and their correction costs.
3. Estimate payment delays – calculate the average number of days invoices are paid after receipt.
4. Check the invoicing route – for transactions within the Belgian B2B obligation, verify structured e‑invoicing support against the official Belgian e‑invoicing guidance.
5. Run the calculator – input your numbers and compare the outcome with the monthly subscription fee.
6. Review regularly – revisit the calculation after a few months to confirm that the expected benefits are realized.

Common concerns

A frequent concern is the perceived time required for implementation. Allocate a focused work session to set up the system, then monitor the actual time spent versus the baseline you recorded.
