Lines from the work done
Hours, payment milestones, approved extra and change work, expenses and purchases move onto the invoice – each line’s source stays visible to the end.
Add-on
The invoice comes from the work done
Kelomo gathers billable hours, payment milestones, extra work and expenses into invoice drafts, numbers the invoice and sends it as an e-invoice or by email. Accounts receivable matches payments by reference number and surfaces what is overdue.

What you get
A numbered invoice, the right VAT
An unbroken number series, a VAT breakdown, a reference number and a virtual bar code. A PDF with your own logo, and a day-by-day work breakdown as an attachment when needed.
E-invoice and email
Send as an e-invoice through an operator, or as a PDF by email. Delivery status updates onto the invoice, and the recipient’s e-invoicing address can be looked up with the business ID.
Credit notes
Credit a whole invoice or selected lines – and re-invoice corrected straight away if needed.
Accounts receivable
Open, paid and overdue invoices with their ageing. Payment reminders and penalty interest go out from the same view.
Recurring contract invoicing
Monthly or quarterly invoices appear as drafts on the run date – fixed lines, and the period’s hours too if you want.
The invoicing decision
Review the lines, decide and invoice.
The invoice draft is assembled at the level you choose – by customer or by project, with lines grouped by phase, task, person or day. Before invoicing, Kelomo checks for missing details on your behalf.
- A decision on every line Invoice it, move it to the next invoice or write it off with a justification. Moved work returns to the billable list and is not forgotten.
- Blockers surfaced before invoicing Unpriced work, a missing VAT number or incomplete seller details show up as a checklist with links to fix them.
- Numbering locks the invoice An invoiced document is frozen: a correction is made with a credit note, and every step stays in an auditable history.
Accounts receivable
See at once who has paid.
Payments are matched by reference number, and the open balance shows on the invoice, on the customer card and as an ageing view – without asking bookkeeping.
- Payments arrive by three routes A fetch from Netvisor, the bank statement as a camt.054 file, or a manual entry. Unmatched payments wait in their own queue to be allocated.
- Overdue items surfaced in time The ageing view shows receivables in 30-, 60- and 90-day buckets, and an overdue invoice lands on the list by itself.
- A reminder on the same reference The payment reminder carries the original invoice’s reference number together with the reminder fee and penalty interest, so the receivable remains one item.
One truth about what is invoiced
The same work is invoiced exactly once.
A line taken onto an invoice locks at its source, so the same hour or expense can only be on one invoice. The invoiced amount is the same in the project margin, on the customer card and in reports.
- A line lock at the source An hour, payment milestone or expense is reserved for the invoice as early as the draft stage, and cancelling an invoice returns the lines to the billable list.
- Billable utilisation per person See in hours and per cent how much of the worked hours ends up on an invoice – against the target. Euros accumulate per project.
- Margin and invoicing side by side The same confirmed hour is a working-time entry, a labour cost and an invoice line, so the margin is calculated from real figures.

Frequently asked
Questions about invoicing
01 Does Kelomo replace a finance system?
No. Bookkeeping, purchase invoices and the financial statements stay in your finance system. Kelomo handles the sales invoice’s journey from the work done to the payment – and, if you prefer, still exports the billing data as before to Netvisor, Procountor, Fennoa, Lemonsoft or as a Finvoice file.
02 How does reverse-charge VAT work?
Sales of construction services are invoiced under the reverse charge (Finnish VAT Act, section 8 c): lines at 0%, the buyer’s VAT number is stored on the invoice – without it the invoice cannot be issued – and the required note is added automatically.
03 Can an invoice be edited after it has been issued?
A numbered invoice is locked, as accounting material should be. A correction is made with a credit note – in full or line by line – and if needed Kelomo opens a new corrected draft right away.
04 Can one Kelomo invoice from several companies?
Yes. There can be several invoicing companies with their own details, number series and logos, and the invoicing company is chosen per invoice.
05 In which languages is the invoice produced?
In Finnish, Swedish and English. The language is chosen per invoice, and the standard texts and the work breakdown follow that choice.
06 How does a recurring invoice know its contents?
The contract defines the fixed lines, the invoicing interval and the run date. Kelomo creates the invoice as a draft – with the period’s hours and expenses too, if you want – and you approve it before it goes out.
07 Who can see the invoices?
Invoices, receivables and the customer’s billing details are visible only to finance roles. The person doing the work sees their own hours and allocation, not invoices or prices.
Invoice the work done without a month-end assembly job.
