Does PeakPilot check the bill against the invoices?

Its pages do not mention it (read on 2026-10-30). Zorowatt rebuilds the bill from the meter data under the grid operator's tariff and sets it against each invoice, line by line, before the battery is sized.

Can I move a site from PeakPilot to Zorowatt?

Yes: upload the same quarter-hour file. Zorowatt reads Excel and CSV exports from any portal and lists every assumption it makes about the file.

Zorowatt vs PeakPilot

Where PeakPilot is strong, where it falls short, and what changes if you switch. Every number can be checked on their site.

PeakPilot is Dutch web software for energy advisers, installers and asset suppliers: it imports quarter-hour data and models the grid connection, PV, EV charging and a battery together, with NPV and payback. Zorowatt also starts from the meter data, then rebuilds the bill under sourced Dutch, German and Romanian tariffs and checks it against the invoices before it sizes the battery. (peakpilot.nl)

Short answer

When to pick PeakPilot: Pick PeakPilot if you work only in the Netherlands and want one model of the grid connection, PV, EV charging and the battery together, with its lead widget and AI adviser.
When to pick Zorowatt: Pick Zorowatt if you want battery sizing and a client PDF on the entry plan, a white-label report for three seats on Pro, the bill checked against the invoices, and German and Romanian sites too.

In short

PeakPilot is the closest Dutch tool to Zorowatt and publishes the same two list prices, €49 and €149. What they buy differs: PeakPilot's €49 plan has no sizing and no PDF, and its €149 plan is per user, without white-label. Zorowatt's €49 plan sizes the battery and writes the report, and its €149 plan covers three seats with your logo. PeakPilot models EV charging in more detail and offers a lead widget, which Zorowatt does not.
