What is distributor billing software?

Distributor billing software is built for businesses that sell from an office or godown rather than a shop counter. Orders come by phone, WhatsApp, a salesman or a dealer, goods go out by delivery, and customers pay later.

O2M runs that whole flow from Orders, without a counter and without any marketplace. Choose the source and outlet, find the customer by phone, name or GSTIN, add items, then save the order or save and invoice in one step.

Money owed builds from every invoice and receipt, so you always know each customer's balance. Set credit limits, send statements, and generate e-invoices and e-way bills from the invoice.

Simple from the first day.

Add customers

Import customers, with GSTINs, balances and credit limits.

Step 2

How to choose distributor billing software

What matters when you sell on credit from an office.

  • Orders without a counter

    You should be able to run the whole business from orders and invoices.

  • Credit control

    Limits and holds protect you before a bad debt happens.

  • E-invoice and e-way bill

    These should start from the invoice, not a separate portal login.

  • Teams

    Each sales team should see its own customers and numbers.

  • Loose goods and units

    Check support for decimal quantities if you sell by weight or volume.

  • Warehouse work

    Add cartons, pallets and picking when volumes grow.

Dealer and Distributor Billing: your questions answered.

Can I use this without a shop counter?

Yes. Businesses that sell only from an office can run on orders and invoices alone.

Can I invoice when goods leave rather than at the order?

Yes. Choose invoice at order or at dispatch.

Do you support loose goods?

Yes. Sell by weight or volume, in decimals.

Can each salesman see only their customers?

Teams see only their own orders and money owed. A customer is shared across the company, so any team can find and bill them.

Can I take an advance?

Yes. Record the advance on a proforma invoice, and the final invoice uses it.

How do I record a cheque?

Open Money owed, choose the customer and record a receipt by cheque against the invoices.

Do you support e-way bills?

Yes. Make e-way bills for invoices through your GST provider, and change the vehicle if needed.

Can I use more than one GSTIN?

Yes. Each warehouse can have its own GSTIN.

Is this a distributor management system?

O2M manages your own orders, billing, credit, stock and sales teams as a distributor. It does not track the sales your retailers make.
