Wholesale is a different game from retail. Bills are fewer but bigger, almost every customer is a registered business, and most of them buy on credit. A distributor can run on a 4–6% margin and still lose money if collections slip by a month. Wholesale billing software therefore has two jobs: make clean B2B GST invoices fast, and keep a tight grip on who owes what. This guide covers both.
What Wholesale and Distribution Billing Needs
- B2B tax invoices with the buyer's GSTIN, HSN codes and the right CGST/SGST or IGST split.
- A party ledger for every retailer and supplier: bills, payments, returns and the running balance.
- Credit control: limits, credit days and a warning before you bill past them.
- Party-wise prices: retailer A gets one rate, retailer B gets another, loaded automatically.
- Collections: ageing of dues, reminders, cheque tracking.
- Movement documents: delivery challans and e-way bills.
B2B GST Invoices Done Right
Your buyers claim input tax credit on your invoices, so every field matters: their correct GSTIN and state, HSN codes, taxable value and the tax split. If the buyer's state differs from yours, it is an inter-state sale and IGST applies. Our GST invoice format guide lists every mandatory field.
A wrong GSTIN is the most common B2B error. It sends the credit to the wrong business and gets you a phone call a month later. Software that can fetch a party's registered name and address from their GSTIN, and that stores the GSTIN once in the party master, removes most of these errors.
The Party Ledger: Your Real Balance Sheet
Every retailer you supply should have a ledger that answers, in one screen, "how much do they owe and since when?"
| Date | Entry | Debit | Credit | Balance |
|---|---|---|---|---|
| 1 Oct | Opening balance | ₹48,500 | ||
| 4 Oct | Invoice 0231 | ₹62,300 | ₹1,10,800 | |
| 9 Oct | Payment received (NEFT) | ₹50,000 | ₹60,800 |
Share this statement with the retailer before every collection visit, so there is no argument about the figure.
Credit Limits and Credit Days
Set two numbers for every customer:
- Credit limit: the most they can owe at any time, for example ₹1,00,000.
- Credit days: how long each bill can stay unpaid, for example 30 days. A bill dated 1 October is then due on 31 October.
With the ledger above, a new ₹45,000 order would take the balance to ₹1,05,800, over a ₹1,00,000 limit. Good software warns the billing clerk before saving, so the decision is made consciously, not discovered at month-end.
Sort outstanding bills by age: 0–30, 31–60, 61–90 and over 90 days. Money stuck past 60 days is where bad debts are born. Chase the oldest first, not the biggest.
Party Price Lists and Schemes
Distributors rarely have one price. A large retailer gets a better rate than a small one, and a sub-dealer gets a dealer rate. Keeping that in a diary means the billing clerk guesses. A party price list stores each customer's agreed rates, so picking the customer loads the right price on every line.
Salesmen, Cheques and Collections
- Salesman-wise sales: tag each bill to the salesman who booked the order and see their sales report.
- Post-dated cheques: record each PDC with its date, so you deposit it on time and know which ones bounced.
- WhatsApp reminders: send a polite reminder with the amount and your UPI ID before and after the due date.
- Supplier outstanding: the same ledger view for what you owe your principals.
Delivery Challans and E-way Bills
When goods leave on your vehicle before the final invoice, a delivery challan covers the movement. For consignments worth more than ₹50,000, an e-way bill is generally required (some states set different limits for movement within the state). Record the e-way bill number and vehicle number on the invoice, so the driver's paperwork and your books match.
Purchases, Godowns and Stock
Distribution is as much about buying right as selling. Purchase orders, goods receipt and the supplier's bill should tie together, and if you keep stock in more than one godown, each should have its own count. See our guide to inventory management for small business for the stock side.
Billux for Wholesale and Distribution
Billux covers this workflow on one platform:
- B2B tax invoices with automatic IGST for out-of-state buyers, delivery challans and proforma invoices
- Party ledger, customer and supplier outstanding reports, and a dues list with collect-payment and WhatsApp reminder buttons
- Credit limit warning on the invoice screen
- Salesman tagging and reports, and cheque (PDC) management
- E-way bill number and vehicle number on invoices
- GSTR-1, GSTR-3B and a Tally XML export for your CA
The Standard plan (₹2,500 a year) covers all of the above. Professional (₹5,500 a year) adds party price lists, the purchase order to goods receipt to bill workflow, multiple godowns and unlimited users. See pricing, or compare Billux with Tally and Marg, two common choices among distributors. Hardware and building-material traders can also read our hardware shop billing guide.
A Distributor's Daily Routine on Software
- Morning: open the dues list and plan collection visits, starting with the oldest balances.
- Order booking: turn salesmen's orders into invoices, with each retailer's prices loading automatically.
- Dispatch: print invoices or challans with the vehicle and e-way bill numbers before the van leaves.
- Evening: post the day's collections, including cash, NEFT and cheques, against the right bills.
- Weekly: review ageing, put customers over their limit on hold, and check slow-moving stock.
Twenty minutes of this every day replaces the month-end scramble of matching payments to bills.
If you are a registered MSME supplier
Under Section 15 of the MSMED Act, a buyer must pay a registered micro or small enterprise within the agreed credit period, and that period cannot exceed 45 days (15 days if nothing was agreed). Late payment attracts interest at three times the bank rate, and disputes can be filed on the government's MSME Samadhaan portal. Since 2024, income-tax rules also let a buyer deduct such purchases only when paid on time. If you have Udyam registration, print it on your invoices. It is a polite way to remind business customers of the 45-day rule.
The Bottom Line
In wholesale, the invoice is the easy part. The ledger, the credit limit and the weekly look at ageing dues are what protect your margin. Pick software that puts those three in front of you every day.
Frequently Asked Questions
What is the best billing software for wholesale business?
Look for B2B GST invoicing, a party ledger, credit limits and credit days, party-wise price lists, salesman reports, cheque tracking, e-way bill details and GST and Tally exports. Test it with your own parties and items before deciding.
How do I manage credit customers in wholesale?
Give every customer a credit limit and credit days, record every bill and payment in their ledger, review dues by age every week, and send reminders before and after the due date.
Is an e-way bill required for wholesale deliveries?
An e-way bill is generally required when goods worth more than ₹50,000 move by vehicle. Some states set different limits for movement within the state.
What is a party ledger?
A party ledger is the running account of one customer or supplier: every invoice, payment, return and the balance after each entry. It shows exactly how much they owe and since when.
Can billing software apply different prices for different customers?
Yes. A party price list stores each customer's agreed rates, and selecting that customer on a bill loads their price for every item.
