The key guides in one place
These three topics help most business owners right away: getting paid, recording costs, and fixing mistakes.
Workflow
From quote to invoice
UurKlus follows the normal route from agreeing work to tracking time and invoicing.
Quotes
Create a proposal for your client and turn accepted work into a project or invoice later.
Projects
Group work, rates, locations, and agreements per client.
Clients
Save client details, language, invoice address, and VAT details before invoicing.
Time entries
Track time per project and use it on your invoice afterwards.
Bookkeeping
From entry to report
These parts feed your reports, VAT overview, and year-end figures. Keep them consistent, and corrections stay small.
Recording expenses
Correct the source data and reconcile a filed return with its recorded amounts. For a difference already posted, use a correction case without a second journal entry.
Assets and depreciation
Record larger purchases as assets, depreciate them over several years, and keep the book value clear.
Correcting invoices
You can edit draft invoices. Final invoices are corrected cleanly with a credit invoice or a new invoice.
Expenses and ledger
VAT treatment, use and ledger account determine the posting. Check your VAT profile, deduction entitlement and the evidence for foreign transactions.
Corrections
Correct an invoice, expense, or VAT amount
Mistakes are fine as long as you fix them in the right way. This is the simple route.
Edit drafts directly
If an invoice is still a draft, edit it directly. Nothing has been posted as final yet.
Correct final invoices visibly
If an invoice is final, create a credit invoice or an additional invoice. This keeps the audit trail correct.
Check the VAT return first
Correct the source data and reconcile a filed return with its recorded amounts. For a difference already posted, use a correction case without a second journal entry.
Use the EUR 1,000 threshold
For errors in a filed return, assess related differences together. Include a VAT difference up to EUR 1,000 in the next return. Above that, file a supplementary return as soon as possible and within 8 weeks of discovery.
Important for the Dutch Tax Administration
UurKlus retains correction cases and recorded return reports. You submit returns and supplementary returns yourself and retain the confirmation. New credits and current tax events are not automatically errors in earlier returns.
