COMMON QUESTIONS

Asked before hiring us.

Our invoices are full of manual errors. Can this stop?

Yes — that's the point. Rules are encoded once, tested against your historical edge cases, and every figure traces back to its source. Errors stop being a Tuesday.

Can it handle our weird pricing?

Bespoke pricing is exactly why you'd build rather than rent. Tiered, negotiated, seasonal, per-seat plus usage — if you can describe it, we can encode and test it.

Is card data safe?

Card details never touch your servers — they go straight to Stripe's PCI-DSS Level 1 vault. We design the integration so your compliance burden stays minimal.
