The challenge
Where they started
- Monthly invoicing consumed six finance days, assembling trips from driver logs, emails, and paper duty slips.
- Complex corporate contracts with slabs, packages, and extras were rated by hand, and errors eroded client trust.
- Billing disputes were routine and slow to resolve because trip evidence lived in three different places.
The solution
What changed
- Encoded every corporate contract as a rate card: slabs, packages, waiting time, and extras priced automatically.
- Digital duty slips with e-sign attached evidence to every trip, feeding trip-level reconciliation.
- Zero-touch billing cycles now generate, send, and sync invoices to accounting automatically.
“Invoicing used to take my team six days a month. It's now fully automatic and our billing disputes have essentially disappeared. The ROI was obvious within one quarter.”
