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 pharmacy's purchasing control has three parts: purchase orders prepared from reorder levels and supplier quotes, an approval ceiling above which the superintendent pharmacist or owner must sign off, and a three-way match of order, delivery note and invoice before payment. Medical products are zero-rated for VAT under the Nigeria Tax Act 2025, according to published summaries.
Why purchasing needs a ceiling
Stock is a pharmacy's largest use of cash, and purchasing is where it leaks: duplicate orders, short deliveries paid in full, prices that drift above the quote, and slow movers bought because a sales representative offered a deal. A written purchase order (PO) and a clear approval ceiling fix most of this without slowing the counter.
Preparing the purchase order
- Start from reorder levels for each line, set from usual weekly sales and the supplier's delivery time.
- Check what is already on order so nothing is ordered twice.
- Get or confirm the supplier's current price; note any price change against the last order.
- Check expiry expectations: for short-dated stock, order quantities you can sell before expiry.
- Prepare the PO with supplier, lines, quantities, unit prices, total, expected delivery date and payment terms.
- Send it for approval if the total is above the ceiling, or if it includes a new supplier or a new product line.
Buy only from suppliers you have checked are properly licensed, and confirm products carry valid NAFDAC registration details. Check the Pharmacists Council of Nigeria's and NAFDAC's current requirements for your premises; they are not summarised here.
Setting the approval ceiling
| Purchase | Approval |
|---|---|
| Routine reorder, existing supplier and line, under the ceiling | Pharmacist on duty or store manager |
| Any PO above the ceiling | Superintendent pharmacist or owner |
| New supplier, or change of a supplier's bank details | Owner, with a call-back to a known number |
| Controlled or high-value lines | Superintendent pharmacist, whatever the amount |
| Price more than an agreed percentage above last order | Owner |
Worked example: a PO above the ceiling
Example only. The ceiling for single approval is ₦500,000. This week's reorder from a distributor is:
| Line | Quantity | Unit price | Line total |
|---|---|---|---|
| Product A (pain relief) | 40 packs | ₦6,500 | ₦260,000 |
| Product B (antimalarial) | 25 packs | ₦9,800 | ₦245,000 |
| Product C (oral rehydration) | 60 packs | ₦3,950 | ₦237,000 |
| Total | ₦742,000 |
The total is ₦742,000, above the ₦500,000 ceiling, so it goes to the owner. The owner sees that Product B's unit price is up from the last order and asks the distributor to confirm it before approving. That one check is the point of the ceiling.
Deals from sales representatives
Distributors' representatives often offer bonus stock or a discount for a larger order. Treat these as ordinary purchases: the PO must still pass the ceiling, and the question is whether the extra stock will sell before expiry. A free carton that expires on the shelf is not free; it ties up space and has to be destroyed. Record the deal on the PO so the invoice can be checked against it.
Credit terms matter too. If a distributor gives 30 days, schedule payment for day 30 rather than paying on delivery, but never let terms lapse into late payment, which costs goodwill and sometimes the terms themselves.
The three-way match before paying
When the stock arrives, compare three documents line by line: the approved PO, the delivery note signed on receipt (counting what actually arrived, with batch numbers and expiry dates), and the supplier's invoice. Pay only for what was ordered and received at the agreed price. Short deliveries, wrong items or short-dated stock go back to the supplier for a credit note before payment, not after.
Tax points on stock purchases
- VAT: medical products and services are listed as zero-rated under section 187 of the Nigeria Tax Act 2025, per Mondaq's summary. Some lines a pharmacy sells (cosmetics, for example) may not be medical products; check each category with your accountant. See VAT on medicines.
- Withholding tax: under the WHT Regulations 2024, as summarised by Mondaq, companies deduct WHT on certain payments, with a 2% rate for supply of goods by residents and manufacturers treated differently. Whether it applies to your pharmacy's payments depends on your structure and the supplier; confirm with your accountant before deducting.
- Keep POs, delivery notes and invoices with your books: the NTAA 2025 requires records for at least six years after the year of assessment.
What to check first
- Every purchase has a PO, even small ones.
- The person who receives stock is not the person who approves payment.
- Supplier bank details are changed only after a call-back.
- Expiry dates are recorded at receipt.
- Credit notes for returns are tracked until received.

Where Pryme fits
The Finance agent on a Pryme Business Account can prepare POs from your reorder levels, flag price changes and prepare supplier payments once the three-way match is done. Anything above the ceiling you set waits for a named person to approve it, and every step is recorded. Pharmacies with a Pryme Business Account can also join Spaces in the Pharmacies sector.
