How we compare
We sell invoice-api.xhub. Our comparisons are therefore not a neutral test, and we do not pretend they are. This page states the rules they follow, so you can check every statement yourself.
- 1
Vendor-owned sources only
A statement about another vendor rests on that vendor's own pages: pricing page, help centre, API documentation, store listing or project repository. Forums, third-party blogs and comparison portals do not count.
- 2
Every sourced row of the table has a reference
In the comparison table, a sourced statement carries a footnote with a link and a verbatim quote. The footnotes sit directly below the table. This does not yet hold throughout for the running text and the questions below it; the table is what counts.
- 3
What we cannot source is marked “unverified”
If we find no source on the vendor's pages, the statement in the table is marked “unverified”. Read such a row as our assessment, not as a fact: the vendor may well support it, we just did not find it.
- 4
Our own column comes from the product
What we say about ourselves is meant to come from the same sources as the rest of the website: availability from the product status (planned endpoints carry their quarter), prices from the price list, the number of countries from the OpenAPI specification. Prices are net, plus VAT.
- 5
Re-checked once a quarter
We open the sources again once a quarter and read them. Every comparison page states the date of the last check at the top. If it is more than 105 days old, an automatic control on our side refuses the next publication until the check is done.
- 6
When the other one fits better
Every comparison page has a section that says when the other vendor is the better choice. An e-invoicing API does not replace accounting software, and we say so.
Is something wrong?
Write to hello@xhub.io, ideally with the source. This explicitly includes notes from the vendors we name. We check the note and correct the page if it holds.
