Paying freelancers without endless invoice checking

Checking freelancer invoices by hand costs time after every event. What a credit invoice on approved hours delivers in practice — and what still travels if full self-billing is not used in your country.

Updated 2026-07-20

After worked hours are submitted, checked, and approved, many agencies and caterers still face a time-consuming step. Freelancers each send their own invoices, which all have to be checked and paid by hand. If something is wrong, the invoice is corrected and resent, then checked again before it can be paid. Flooptimize can make that smoother.

What goes wrong with loose freelancer invoices

Freelancers send their own invoice after the weekend (or later). You have to check whether hours, rate, period, and details match what was actually worked. Typical pressure points:

  1. Invoices arrive scattered — one emails, another WhatsApps; you have to store them somewhere structured.
  2. Manual comparison with the schedule — looking up shifts, hours, and rates again.
  3. Wrong or incomplete invoices — wrong hours, missing details; back-and-forth with the freelancer.
  4. Delayed payout — you can only move on when everything checks out.
  5. Double work after peak weekends — many invoices in a short window, all the same checks.

What a credit invoice means in practice

In short: you (or your system) create a credit invoice for the freelancer based on agreed hours and rates, instead of waiting for everyone to send their own invoice for you to check.

The core is: one source for “what is approved worked”, and the invoice from that. So the invoice does not become a second, loose truth next to your hours.

How you set this up legally and for tax depends on your situation — you check that with your advisor. Here the point is operational: less checking of loose PDFs, more alignment with hours you already have.

What Flooptimize changes

Flooptimize does not replace your bookkeeping or accountant. It ties credit invoices to approved worked hours in a period you select:

  • Hours correct first — workers confirm in the employee portal; you approve in the backoffice (partly within thresholds you set).
  • Credit invoice in one click — for freelancers with approved hours in that period you can create a credit invoice, instead of dissecting every loose invoice (where that is allowed for you).
  • Less back-and-forth on amounts — the invoice builds on hours that already belong to the shift. If you do not self-bill, you can still share those amounts and line items so freelancers invoice correctly.

On the path to approved hours: Processing hours and payouts can be done quickly, without endless spreadsheets.

What Flooptimize does not do

No contractor-compliance legal advice, no guarantee about your tax position, no full accounting suite. Payroll export for employed staff is a separate path; credit invoices cover the freelancer stream where you use them. Formal compliance and contracts stay your responsibility (and your advisor’s).

When loose invoices are still fine

With few freelancers, few events, and someone who can check each invoice quickly, manual can still work. Once volume grows — more people, more weekends, more exceptions — checking loose invoices costs more than a credit invoice on approved hours (or a shared, approved hours summary).

How does Flooptimize fit?

Hours on the shift first, then approval, then a credit invoice where that fits your jurisdiction. You still decide on exceptions; the software keeps payout from starting again at a pile of PDFs that do not match the schedule.
