Feature flags

Deployment mode and locations

Option	Default	Effect
Deployment:Mode	Cloud	OnPremise for a customer installation — the installer sets this, do not change it by hand
DataDirectory	data	the database and tenant files, relative to the installation directory; an absolute path is permitted, and the installer writes one
PublicBaseUrl	https://www.invoiceflair.com	the public address for links in email. Cleared on-premises when not set

Keys and bot protection

Option	Default	Effect
ApiKeysEnabled	true	the key requirement for the /api endpoints
ApiKeysFile	keys/api-keys.json	the key store (SHA-256 hashes only), relative to the installation directory
BotProtectionEnabled	true	a honeypot field and a signed timing trap on all form pages
BotMinFormSeconds	1	the minimum time between a form being shown and submitted

Two switches that change the output

Option	Default	Effect
TaggedPdfEnabled	false	produces the visual layer of the hybrid invoice as a tagged PDF (PDF/UA-1 on PDF/A-3a): a structure tree, table semantics, alternative texts. Switched on, the renderer moves to an embedded font and the file grows. If the tagged run fails, the invoice is produced the previous way
NativeTemplateLayoutsEnabled	false	draws the two supplied templates (“Header”/“Sidebar”) natively instead of via DOCX to PDF — accessible and without an additional licence. Off, because the typeface and line breaks of those two templates change with it; your own uploaded templates are unaffected

Both are off by default and change generated invoices

TaggedPdfEnabled changes the file size and the typeface, NativeTemplateLayoutsEnabled the layout of the two supplied templates. Verify against your own documents before switching over in production.

Promotional notices in the public portal

Option	Default	Effect
AccountNudgeEnabled	false	the account prompt
ProHintEnabled	true	the API hint for heavy validators
SeriesHintEnabled	true	the number-range hint

All three are hard off on-premises

Not configurable. In an installation on your own premises there is nothing to promote.

The name of the operating organisation

Deployment:OrganizationName shows the operating organisation’s name in the footer instead of the product tagline — the vendor link and the legal texts remain alongside it. Empty, or in cloud operation, the tagline stays.

What does not belong here

The Stripe section exists in the same configuration but is irrelevant to an Enterprise installation: in OnPremise mode the billing endpoints are not registered at all.
