InvoicingThe invoice is ready when the job is done
When the job is done, invoicing usually remains: looking up the offer, remembering the extra work, typing everything into accounting. In Rektor, it's all already there: units, quantities, extra work, and prices.
Invoice everything at once or in stages, send to DK or Payday with one click, and follow payment status without opening the accounting system.

What you get
- The invoice is based on the offer and approved extra work, so nothing is entered twice
- Invoice in stages: pick lines and quantities, Rektor remembers what's left
- Materials and out-of-pocket expenses go onto the invoice with your markup, straight from the receipt
- Send straight to DK or Payday, with a bank claim if you want
How it works
The invoice is based on the project
Create an invoice directly on the project. The line items come from the project's units and quantities, including any added Extra Work, so nothing needs to be re-entered.
- Hourly work billed by hours worked pulls in clocked hours that haven't been invoiced, including hours over the estimate.
Materials and expenses
Log purchases for the project, such as lumber from BYKO, and bill them with a markup. Upload the receipt and Rektor fills in the supplier, date, and line items.
- The cost price goes onto the next invoice with your markup, as a single line or item by item.
- Staff send receipts directly from the app to the project, and the office reviews them before they are added to an invoice.
- Purchases are included in the project's costs and profit margin.
Bill in stages
No need to wait for project completion. Each invoice can cover selected lines and partial quantities, and Rektor tracks what remains on each line until everything is billed.
- Extra Work added after the first invoice appears as remaining and goes on the next invoice.
- The same quantity is never billed twice.
Payments and due dates
On each invoice, you record payments and see what remains. Due date and final due date come from the organization's invoice settings, and overdue invoices stand out in the list.
- Partial payments accumulate, and the invoice is automatically marked as paid once fully settled.
- You can edit the invoice text and dates directly on the invoice before it goes to DK or Payday, without having to recreate it.
- The daily overview on the dashboard shows how much is overdue and how many days past due the oldest invoice is.
- You receive a notification when DK or Payday marks an invoice as paid.
DK, Payday, or just Rektor
The invoice is sent to DK or Payday, with a bank claim if you wish. If neither is connected, the invoice is created in Rektor and you track payments there.
- Download the invoice as a PDF, directly from DK or Payday if it was sent there, otherwise Rektor generates it with your organization as the seller.
- If you want to review the invoice in Payday first, it is sent there as a draft, and Rektor sees when you have sent it from there.
