The business bottleneck

Small and mid-sized agencies faced cash flow delays due to manual PDF invoice generation, un-tracked invoice opening, and disjointed cross-border payment links.

  1. Delayed follow-ups on unpaid invoices causing cash flow strain.
  2. Lack of automated recurring subscription billing for retained clients.
  3. Currency conversion confusion and high transaction rejection rates.
