You have had the module installed, guests have purchased electricity in the app, and now you are wondering: when will I see something of this back on my account? The short answer is that you are never charged per purchase, but once per month, in arrears, for everything sold that month. The invoice only follows after the month has closed, showing the subscription per object and the markup per kWh sold.
The reason is simple: there is never automatic collection from a bank account. Staywatt sends you an invoice with a payment link, and that can only be correct once all sales from that month are in. If you rent year-round, that is a fixed, predictable rhythm. If you only rent during the season, you simply receive no invoice in the months when nothing was sold.
From first sale to payment link: the steps
Between the moment a guest first buys kWh and the moment you see an amount on your screen, there are a few steps. The guest scans the QR code, purchases electricity, and the system counts live how much of it has already been consumed. At the end of the calendar month, that total per object is locked in: how many kWh were sold in that month, and what the subscription charge for that month is. Only then is the invoice drawn up and sent, with a link through which you can pay in one go.
This means that the processing time for you consists mainly of waiting for the month-end closing, not of a complicated process on your end. You don't need to collect anything, export anything, or manually add anything up. If you have multiple objects — a holiday home and a charging point, or an entire park with separate units — everything is bundled on one invoice, with a separate line per object.
What is exactly on the invoice
For those who want to know precisely: the invoice shows per object the subscription amount for the past month, the total number of kWh sold, the markup per kWh calculated on that, and VAT. For charging points, this is separated from the tariff for the regular circuits in the accommodation, because each point is a separate object with its own QR code and its own tariff. If you want to know in advance roughly how those amounts relate to your current situation, the overview of subscriptions and markup provides a first impression.
Where the processing time gets stuck in practice
The invoice deadline itself is fixed, but the path to it sometimes runs less smoothly than expected. A common stumbling block is that the module has been installed by the electrician, but has not yet been activated via Bluetooth on the landlord's phone. Without that activation, the system records nothing, and the first month thus remains empty — not because something is wrong, but because the final step simply still needs to happen.
Another point where it often gets stuck is the business account. An invoice can only be properly drawn up and sent once the data of the legal entity is complete: Chamber of Commerce number and VAT number belong there, and the account is tied to that legal entity, not to a loose email address. If something is missing there, it can delay the first invoicing, even if electricity sales to guests are already running. Those who are unsure whether their own situation is complete will usually find clarity quickly in the answers to the most frequently asked questions about invoicing .
At vacation parks with multiple units or standalone charging stations, we sometimes see that one object was accidentally not linked to the correct account, so the sales are registered but don't appear on the park's collective invoice. This can be prevented by checking which account an object is linked to each time you add a new object, before the first guest buys electricity from it.
What you can do yourself to avoid delays
Most delays are not in the invoicing itself, but in the steps before it: activation, registration and linking. Complete those steps early, and the rest follows automatically within the fixed monthly schedule. If you're unsure whether everything is set up correctly for your situation — one property, an entire park, or only charging stations — then the explanation of the complete process from measurement to invoice outlines step by step where each component comes from.
If you don't yet have an account and want to know how quickly you can get started yourself, then creating a business account is the first step that sets the rest of the timeline in motion.
