Invoicing and Fortnox — no more paperwork

It is the 25th of the month. Stable invoices are due. You open the Excel spreadsheet, check who joined, who left, who has add-on services. Then you write invoices one by one and send them by email or bank transfer. Someone pays right away. Someone “forgets”. Three weeks later you are still chasing unpaid invoices.

This takes hours every month. Hours you could have spent in the stable.

The old way

Most stable owners handle invoicing with some combination of:

The result? Hours of administration, incorrect amounts, missed invoices, and a nagging feeling that the books never quite add up.

How EquiDuty handles invoicing

EquiDuty manages the entire chain — from chargeable item to payment and accounting — in one flow.

1. Chargeable items — everything in one place

You define your stable’s chargeable items once:

Each item is linked to the correct VAT rate (25%, 6% for education, or VAT-exempt). You choose whether it recurs monthly or is charged per occurrence.

2. Billing groups — the right price for the right person

Every stable member is assigned to a billing group that determines which items they are charged for. A horse in a box gets the stable place fee. A horse on outdoor board gets the paddock fee. Someone who rides three lessons per week gets the lesson fees automatically.

No need to manually add line items to each invoice. The system already knows what to charge.

3. Automatic billing periods

EquiDuty generates invoices based on periods you choose — monthly, quarterly, or custom. When a period starts, a draft invoice is created with all items totalled per stable member.

You review the draft, adjust if needed, and approve. The invoice is sent automatically.

4. Payment dashboard

The dashboard shows you in real time:

You get a full overview without opening a separate accounting program.

5. Fortnox integration — one click

This is where it really saves time. EquiDuty connects directly to your Fortnox account via API. When you approve an invoice in EquiDuty:

  1. The invoice is created automatically in Fortnox with the correct account, VAT rate, and customer details
  2. Payments sync back — when the customer pays in Fortnox, the status updates in EquiDuty
  3. VAT is correct from the start — no manual adjustments needed

From stable place and lesson to booked invoice — one click.

No double entry. No export files. No discrepancies between systems.

What difference does this make?

Before EquiDuty:

“I spent three evenings getting the January invoices out. Then it took another two weeks to chase payments. And when the accountant checked, the VAT was off.”

With EquiDuty:

“I approved the period invoices in ten minutes. Everything synced to Fortnox automatically. The accountant had no questions.”

Subscriptions and package management

Beyond one-off invoices, EquiDuty also handles subscriptions — ongoing agreements where the stable member pays a fixed amount per month. Perfect for:

The system tracks contract periods, renewals, and cancellations. You do not have to manually stop billing when someone leaves.

Get started

You do not have to migrate everything at once. Start with:

  1. Create an account — invoicing is included in the Pro plan
  2. Add your stable’s chargeable items with amounts and VAT rates
  3. Assign billing groups to your stable members
  4. Connect Fortnox — takes five minutes with an API key
  5. Generate your first billing period — review, approve, done

Within a month you will have a complete picture of your stable’s finances. And you will have your evenings back — the ones you used to spend on Excel and paperwork.


EquiDuty is built for Scandinavian stables. Fortnox integration is available on the Pro plan — try free for 30 days.
