Book a call

Know what's free, what's due, what's overdue.

WhatsApp replies that check live stock, photos at handover and return, and monthly invoices that send themselves, on the sheets, Tally or ERP you already run.

Where rental firms quietly lose the next booking

  • Same unit, two bookings

    A WhatsApp yes and a sheet a day behind put the same laptop or tent on two orders.

  • Due back, still on rent

    The late unit only shows up when the next customer is waiting, or the bill was never sent.

  • Damage with no record

    Without a handover photo, the scratch was already there, and the deposit goes back in full.

  • Invoices sent by hand

    Every rental bill waits on someone remembering to send it. Leave, and the invoice waits too.

One system for the whole rental desk

Start with the leak: a double booking, a messy return, or the monthly bill. It runs on your WhatsApp number, beside Tally or your ERP.

  • Live stock before you say yes

    Every serial or bulk item is free, on rent, or in service, so a WhatsApp yes cannot book the same unit twice.

  • Photos, deposits and the return

    Handover and return photos sit on the order. A damage or late charge waits until someone on your team confirms it.

  • The bill, then the chase

    Each contract invoices on its date by email and WhatsApp. The day 25, 28 and 35 ladder stops when the balance clears.

  • One inbox and today's numbers

    Email and WhatsApp for a client sit on one thread, with on-rent, overdue and billed on your phone, without opening the ERP.

Rent billed on the day, not when someone remembers.

An equipment rental and service business ran billing from an old flat-file system with no reminders, and vendor support that could take weeks. We proposed a one-week pilot: payment reminders on WhatsApp and email, before availability or anything else.

  1. 01Reminders at 25, 28 and 35 days overdue
  2. 02Email and WhatsApp threads grouped by client
  3. 03Built alongside the existing ERP, not instead of it
  • 15 days their ERP vendor can take to answer support
  • 1 week pilot before any bigger build
  • 0 invoices left to memory is the goal of the pilot. Designed with their team; results to follow.

From first call to a desk that knows the stock

  1. Map the hire

    A 30-minute call on how a unit moves: enquiry, booking, handover, return, damage, monthly bill.

  2. Connect your tools

    Sheets or your ERP, Tally, email and your WhatsApp Business number. We copy data out.

  3. Pilot one workflow

    A one-week pilot, usually the reminder ladder, then live in 3 to 6 weeks with accounts approving.

  4. Add the next system

    Availability, return photos or the owner dashboard, once the first workflow earns its keep.

Every charge waits for someone on your team

We provide the system. You stay in control of customer data, deposits and every message that goes out.

  • Reminders from your own number

    Every reminder goes out from your WhatsApp Business account and email, in your words, and stops the moment the balance is cleared.

  • You confirm any damage charge

    Photos flag a scratch, a missing part or a late return. Nothing is added to the bill until someone on your team confirms it.

  • Ready for the DPDP Act

    Customer data stays on your accounts, with access controls and a log of who saw what, so you can answer under India's DPDP Act. We don't give legal advice.

What rental firms ask us

Do we have to replace our ERP or Tally?

No. We copy the rows we need for availability, reminders and the dashboard. Your ERP or Tally keeps the accounts. Invoices can be handed across as a file your accountant imports. We do not overwrite what is already there.

Can a WhatsApp yes double-book a unit?

The reply checks the same stock list the counter uses: free, on rent, or in service. If eight laptops are free, the message says eight. A person confirms the hold before it becomes a booking.

How do damage and deposits work?

At handover and at return, photos and a short checklist sit on the order. The deposit is recorded against that order. A scratch, a missing part or a late day is flagged. Your team decides whether to release the deposit or add a charge.

What happens when a client pays part of the bill?

Reminders follow the balance that is left, not the original total, and they stop once it is cleared. Accounts can see what was billed, what landed, and what is still open.

Does this help with DPDP compliance?

We set access controls and an activity log, and we can walk a data audit with you. Documents stay on your accounts. We do not give legal advice.

Can we try one workflow before a full build?

Yes. The usual start is a one-week pilot on the payment reminder ladder. Availability and return photos come after that one earns its keep. The first system is live in 3 to 6 weeks.

Let's find your first workflow
