AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
A discount comes straight out of your gross profit, so on a 30% margin a 10% price cut needs 50% more units sold just to earn the same gross profit in naira. A written discount policy sets who may give discounts, how much, and on what conditions, and any advertised price comparison must be true: section 123 of the FCCPA 2018 bars misleading claims about earlier prices.
Discounts feel cheap to give because the customer is in front of you and the sale is close. The cost shows up later, in a month where sales were busy but profit was thin. The fix is to know, before you discount, how many extra sales each discount requires, and to put limits in writing so staff do not improvise.
The maths: what a discount does to your margin
Example only. An item sells for ₦10,000 and costs you ₦7,000, a gross profit of ₦3,000 per unit (30% margin). The table shows the gross profit left after each discount, and how many more units you must sell to earn the same ₦3,000-per-original-unit total.
| Discount | Selling price | Gross profit per unit | Extra units needed to match |
|---|---|---|---|
| 0% | ₦10,000 | ₦3,000 | — |
| 5% | ₦9,500 | ₦2,500 | 20% more |
| 10% | ₦9,000 | ₦2,000 | 50% more |
| 15% | ₦8,500 | ₦1,500 | 100% more (double) |
| 20% | ₦8,000 | ₦1,000 | 200% more (triple) |
The formula is: units needed ÷ current units = original gross profit per unit ÷ new gross profit per unit. At 10% off, ₦3,000 ÷ ₦2,000 = 1.5, so you need 1.5 times the units. The lower your margin, the faster this gets out of hand: on a provisions line with a 12% margin, a 10% discount leaves almost nothing. If you need a refresher on the two measures, see markup vs margin.
What a written discount policy should cover
- Purpose. Each discount type has a reason: clearing old stock, rewarding volume, encouraging early payment, or winning a new account.
- Maximum by role. For example, cashiers up to 5% on stated lines, the manager up to 10%, anything higher approved by the owner.
- Excluded lines. Low-margin items, items already on promotion, and lines where supply is tight.
- Conditions. Minimum quantity, payment before delivery, or a time limit.
- Recording. Every discount logged against the sale with the reason and who approved it.
- Review. Monthly check of total discounts given against the extra sales they brought.
Better ways to discount
Volume discounts
Give the discount only above a quantity that lowers your own costs, for example a full carton that saves you repacking, or an order large enough to earn you a supplier rebate. See bulk pricing for wholesale and retail.
Early-payment discounts
Example only. Offering 2% off a ₦500,000 invoice paid within 7 days costs ₦10,000. That is worth it if it saves you borrowing or chasing; it is expensive if the customer would have paid in 14 days anyway. Pair it with clear terms on the invoice, as in getting customers to pay on time.
Value-add instead of price cut
Free delivery within a zone, a small free item, or an extended warranty may cost you less than the same value off the price, because the customer values it at retail and you pay cost. Any warranty you offer must be one you can honour.
Checking whether a discount worked
Judge a discount by gross profit in naira, not by sales or footfall. Compare the same period before and during the offer, and include the units sold to customers who would have bought at full price anyway.
Example only. The ₦10,000 item normally sells 200 units a fortnight, earning ₦600,000 gross profit (200 × ₦3,000). During a two-week 10% offer it sells 260 units. Revenue rises from ₦2,000,000 to ₦2,340,000, which looks like success, but gross profit falls to ₦520,000 (260 × ₦2,000), ₦80,000 less than doing nothing. To break even the offer needed 300 units.
- Track units, revenue and gross profit for the line before, during and after.
- Watch for a dip after the offer, when customers who stocked up stop buying.
- Note any knock-on sales of other items, which can justify a small loss on the discounted line.
- Stop or change any offer that fails the test twice.
The law on advertised discounts
Section 123(1) of the Federal Competition and Consumer Protection Act 2018 prohibits a trader from making representations that are misleading in a material respect, including about price, price comparisons with earlier or competitors' prices, and the price at which goods have usually been sold. It also covers warranties or guarantees with no reasonable prospect of being honoured. Section 123(2) treats signs and in-store displays as made by the business.
- Show a 'was' price only if you actually sold at that price for a meaningful period.
- State any conditions (minimum spend, lines excluded, end date) on the same sign.
- Keep evidence of earlier prices, such as dated price lists or till records.
- Do not claim 'lowest price in town' unless you can support it.
This is general information, not legal advice. On the buying side, IAS 2 (paragraph 11) requires trade discounts and rebates you receive from suppliers to be deducted from the cost of stock, which improves your margin on paper only when they are actually earned.
Where Pryme fits
Discounts on invoices are easier to track when billing is in one place. Pryme Business Accounts include invoicing and a Finance agent that prepares reports for a person to approve, so a monthly review of discounts given takes less time to pull together.
Questions people ask
How much discount can a small business afford?
It depends on your margin. On a 30% margin, a 10% discount needs 50% more units to keep the same gross profit. Work out the extra sales needed before you offer it.
Is it illegal to fake a sale price in Nigeria?
Section 123 of the FCCPA 2018 bars misleading representations about price comparisons with earlier prices. A 'was' price should be one you really charged.
What is an early payment discount?
A small reduction, such as 2%, if a customer pays within a set number of days. It costs you that amount in exchange for faster cash.
Should my staff be allowed to give discounts?
Only within written limits. Set a maximum by role, list excluded items, and log every discount with a reason and approver.
