Wave: sovereignty score and 8 European alternatives

Wave is online accounting and invoicing software for small businesses and sole traders. The service combines bookkeeping, invoices, payments, receipt capture, a mobile app, payroll and access to bookkeeping and accounting advisers in one environment. Wave is offered as SaaS through the browser and the app; bank connections run through Plaid and, according to Wave, are read-only. The product is aimed at the Canadian and US markets.

Wave Financial Inc. is Canadian and, according to press releases, was acquired by US-based H&R Block in 2019, which now owns it. Where customer data is stored is not stated, and no EU storage option is described. Whether Wave makes a GDPR or processor commitment is not stated. A European organisation should take into account the US parent, which makes the CLOUD Act relevant, and the lack of documented EU data residency.

Why digital sovereignty matters with Wave

Wave is headquartered in CA, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor. The ultimate owner is based in US. Foreign control undermines part of the certainty a European headquarters offers.

Wave hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Wave is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Wave together with your other vendors and gives a total score, a heatmap and the main risk drivers.
