A wholesaler lives in a completely different world from a retailer.

Revenue runs into the millions, but margins are painfully thin. Inventory is large and varied, receivables are huge, and a lot of them are overdue. Any error in pricing or stocktaking costs real money.

This guide is written for the wholesaler — whether you trade in building materials, food or industrial goods.

## The challenges specific to wholesalers

Wholesalers face challenges that many system vendors simply do not understand:

- Inventory volume is enormous: thousands of items across large warehouses
- Most selling is on account: 80% or more of sales are on credit
- Collection is slow: a large share of receivables runs months late
- Margins are thin: a single costing error eats the whole profit
- Invoices are numerous and complex: one invoice may carry dozens of line items
- Supplier relationships are complicated: large purchase orders and varying discounts

## Managing large inventory

A wholesaler's inventory needs specialised handling:

What you need:
- Tracking thousands of items with high accuracy
- An alert whenever an item hits its reorder point
- Multiple warehouses with stock transfers between them
- Slow-moving product reports, so capital is not left frozen
- Inventory valuation on weighted average or FIFO

An accurate inventory balance means:
- Knowing what you hold before you promise it to a customer
- Avoiding duplicate orders to the supplier
- Knowing what your inventory is worth when you go for financing

## Managing receivables and credit customers

This is the beating heart of any wholesale business — and the biggest source of headaches.

What you need to manage:
- A credit limit set for every customer
- Every invoice tracked against its due date
- A statement of account for any customer at any time
- Debt aged into buckets: 0-30 days, 30-60, and over 60
- Automatic notifications when payment falls late
- A report of the oldest and largest debts

A golden rule for wholesalers:
If your receivables exceed 60 days of revenue, you are financing your customers out of your own pocket — and that drains your liquidity.

## Pricing and profitability in wholesale

Wholesale margins are thin — and a pricing mistake hurts badly.

Pricing challenges:
- Purchase prices shift with every shipment from the supplier
- Volume discounts complicate the calculation
- Each customer may carry a custom price
- Delivery cost is not always factored in

What the system has to do:
- Update the purchase cost automatically with every new purchase invoice
- Calculate the profit margin on every item
- Alert you if a product is sold below cost
- Hold different price lists for different customers
- Calculate volume discounts automatically

## VAT on invoices you never collected

Overdue receivables at a wholesaler are not only a liquidity problem. You have already paid output tax on an invoice whose value has not reached you yet.

The VAT Implementing Regulations allow output tax to be reduced on unpaid consideration, but only under conditions that must all be met together:

| Condition | What it means in practice |
| --- | --- |
| Prior declaration and payment | You must have included the tax calculated on the supply as output tax in your return and actually paid it |
| An unrelated customer | The consideration must arise from a supply made to a person not related to you |
| Twelve months elapsed | At least twelve months must have passed since the date of the taxable supply |
| A write-off certificate | A certificate from a chartered accountant licensed and certified in the Kingdom showing that the debt has been written off the commercial books; the Authority may accept other supporting documents if you are not required to appoint an auditor |
| More than SAR 100,000 | If the unpaid amount exceeds SAR 100,000 and you have formally pursued legal proceedings without result, you submit evidence of this, such as a court judgment or the debtor's bankruptcy |

Two things to watch. A taxpayer accounting on a cash basis does not make this adjustment at all. And if you collect the amount later, the tax falls due on it again in the return for the period in which payment was made, with a new tax invoice issued to reflect the amount received.

## The other side: paying suppliers late reverses your input tax

The rule runs in both directions, and this is what catches out wholesalers who stretch their payment terms with suppliers.

If you deducted input tax on a supply you received and have not paid for it in full after twelve months have passed from the month following the month in which the supply took place, you must adjust the deductible input tax by the amount of tax calculated on the balance still unpaid. The adjustment is included in the return for the tax period covering the month in which the twelve-month period ended.

If you pay later, the deduction may be increased again by the amount settled, in the return for the period in which payment was made or any subsequent period.

Supplies of goods under financing contracts are excluded — among them finance leasing, Murabaha and lease ending with ownership — where they are received from a taxable person licensed under the applicable regulations and paid in periodic instalments. The conditions include the contract remaining in force with no litigation over it, the supplier having declared the full tax due, and your holding a written certificate from the supplier to that effect.

In practice: your supplier ageing report is not merely an accounting report, it is a schedule of tax obligations. Make reviewing it part of your monthly close in the [accounting system](/accounting).

## The summary invoice: the wholesale tool most traders overlook

A customer who takes three shipments a week from you does not need three invoices a week.

The Regulations permit a summary tax invoice covering several separate supplies of goods or services made to a single customer within a period of no more than one calendar month, provided it carries the statutory details of a tax invoice and is issued no later than the fifteenth day of the month following the calendar month it relates to.

The same rule governs the timing of an ordinary invoice: a tax invoice is issued no later than the fifteenth day of the month following the month in which the supply took place.

The simplified tax invoice is an exception limited to supplies worth less than SAR 1,000, and that does not cover most wholesale invoices. Your invoice to a trader must be a full tax invoice carrying every required field.

The practical arrangement: a delivery note for each shipment, then one summary invoice at the end of the month. Fewer documents, and a clearer statement of account when you come to collect.

## What changes once your supplies cross SAR 40 million

Growth changes a wholesaler's tax rhythm before it changes anything else in the business.

| Item | Rule |
| --- | --- |
| Tax period | One month for taxpayers whose annual taxable supplies exceed SAR 40,000,000 during the previous twelve months, and three months for everyone else |
| Tax payment | No later than the last day of the month following the end of the tax period |
| Late filing of the return | 5% to 25% of the value of the tax that should have been declared |
| Late payment of the tax | 5% of the value of the unpaid tax for each month or part of a month |
| Failure to keep invoices, books and records | A fine of up to SAR 50,000 |
| Retention period | At least six years from the end of the tax period they relate to |

One detail that gets overlooked: records are kept in Arabic, and every invoice is issued in Arabic in addition to any other language it may also be issued in.

Moving from a return every three months to a return every month means twelve closes a year instead of four. So if posting purchase invoices or counting the warehouse runs two weeks late, you will enter every cycle already behind. Get your goods receipt and stocktake cycle under control in the [inventory system](/inventory) before you cross the threshold, not after.

## Zakat: why large inventory raises your Zakat base

A question wholesalers ask again and again: my inventory is huge and my liquidity is weak, so why is my Zakat so high?

The answer sits in the Zakat Collection Implementing Regulations:

- Inventory is not a deductible item from the Zakat base, and goods held for sale are not deducted even before they are finished
- Materials not held for sale, such as spare parts, are deductible items
- Provisions are treated like equity, so they are added back at their closing balance, with the exception of the end-of-service gratuity provision and the statutory leave provision
- The values shown in the statement of financial position at the end of the Zakat year are the ones used
- The Zakat rate is two and a half percent of the Zakat base for the Hijri year, and if the Zakat year differs from the Hijri year it is calculated on actual days

The direct consequence for a wholesaler: the doubtful-debt provision you set up to reflect the reality of your receivables is added back to the base. It lowers your accounting profit and does not lower your Zakat. Estimate the effect on your own numbers with the [inventory Zakat calculator](/tools/finance/zakat-inventory-calculator) before you file, not after.

## E-invoicing: where your supply chain sits in the waves

Most wholesalers passed the thresholds of the early waves years ago. But the later waves widen the circle to smaller businesses inside the same supply chain. Your distributor or your agent in another region may be in scope now, and the invoice they send you is part of your own tax file.

The Authority has set the criteria for Wave 25 of the integration phase: taxpayers whose VAT-taxable revenue exceeded SAR 187,500 during 2022, 2023, 2024 or 2025, who must integrate their solutions with the Fatoora platform no later than 1 February 2027.

Review the [wave details and readiness requirements](/zatca/wave-25), and make sure your smaller suppliers know where they stand before their invoices stop flowing to you.

## Frequently asked questions

### Can a credit limit be set for each customer?

Yes. You can set a credit limit for every customer and receive an alert as they approach or exceed it.

### Does Snad support sales rep commission management?

Yes. You can track each rep's sales and calculate their commissions against targets set in advance.

### How do I handle wholesale returns in Snad?

Snad supports both sales and purchase returns, issuing credit notes and updating inventory automatically.

### When can I reduce output tax on an invoice the customer has not paid?

When the conditions in the VAT Implementing Regulations are met together: you must have declared and paid the tax on the supply, the customer must not be related to you, at least twelve months must have passed since the date of the taxable supply, and you must submit a certificate from a chartered accountant licensed and certified in the Kingdom showing that the debt has been written off the commercial books. If the unpaid amount exceeds SAR 100,000 and you have formally pursued legal proceedings without result, you submit evidence of this, such as a court judgment or the debtor's bankruptcy. A taxpayer accounting on a cash basis does not make this adjustment.

### Must input tax be reversed if I am late paying a supplier?

Yes. If you deducted input tax on a supply you received and have not paid for it in full after twelve months have passed from the month following the month in which the supply took place, you must adjust the deductible input tax by the amount of tax calculated on the balance still unpaid, within the return for the tax period covering the month in which that period ended. If you pay later, the deduction may be increased again in the return for the period of payment or any subsequent period. Supplies of goods under financing contracts are excluded, subject to specific conditions set out in the Regulations.

### Can I issue a single invoice to a customer who receives multiple shipments during the month?

Yes. The Regulations permit a summary tax invoice covering several separate supplies to a single customer within a period of no more than one calendar month, provided it carries the statutory details of a tax invoice and is issued no later than the fifteenth day of the month following the calendar month it relates to.

### When does a wholesaler move from quarterly filing to monthly filing?

The tax period is one month for taxpayers whose annual taxable supplies exceed SAR 40,000,000 during the previous twelve months, and three months for other taxable persons. The tax due must be paid no later than the last day of the month following the end of the tax period.

### Is inventory deducted from the Zakat base?

No. Under the Zakat Collection Implementing Regulations, inventory is not a deductible item from the Zakat base, and goods held for sale are not deducted even before they are finished. Materials not held for sale, such as spare parts, are deductible items. The Zakat rate is two and a half percent of the Zakat base for the Hijri year, calculated on actual days if the Zakat year differs from the Hijri year.

### How long must VAT invoices and records be retained?

At least six years from the end of the tax period they relate to, with a longer period for records relating to capital assets. Records are kept in Arabic, and every invoice is issued in Arabic in addition to any other language. The fine for failing to keep invoices, books and records reaches SAR 50,000 per the Authority's penalties and fines page.
