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
In a documentary collection, the UAE seller's bank sends the shipping documents to the Nigerian buyer's bank, which releases them only against payment (documents against payment, D/P) or against the buyer accepting a bill of exchange to pay later (documents against acceptance, D/A). The banks handle documents but do not guarantee payment, so it is cheaper than a letter of credit and riskier for the seller.
How it works
A documentary collection uses banks as the channel for documents, not as guarantors. The UAE seller ships, then hands its bank the shipping documents (above all the original bill of lading) with instructions. The seller's bank forwards them to the buyer's bank in Nigeria, which presents them to the buyer. The buyer gets the documents, and with them control of the cargo, only on the seller's terms.
- Seller and buyer agree D/P or D/A in the contract and the proforma invoice.
- Buyer opens a Form M with "bills for collection" as the payment mode; Sterling Bank's Form M FAQ lists it alongside letters of credit and advance payment.
- Seller ships and lodges the documents with its UAE bank, with a collection instruction.
- UAE bank sends the documents to the buyer's Nigerian bank.
- Nigerian bank presents them: under D/P the buyer pays; under D/A the buyer accepts a bill of exchange due on a future date.
- Buyer receives the documents and clears the goods.
- Payment travels back to the seller's bank.
D/P or D/A
| Documents against payment (D/P) | Documents against acceptance (D/A) | |
|---|---|---|
| Buyer gets documents | After paying | After accepting a bill of exchange |
| Buyer pays | At presentation | On the bill's maturity date |
| Seller's risk | Buyer refuses to pay; goods sit in Lagos | Buyer takes the goods and does not pay at maturity |
| Suits | New or medium-trust buyers | Long, stable relationships |
Under D/A the buyer can sell the goods before paying, which is why it is effectively credit from the seller.
What the banks do not do
The banks act as a channel. They do not give a payment undertaking and do not guarantee that the buyer will pay; they may debit the buyer's account only if the buyer authorises it. That is the core difference from a letter of credit, where the issuing bank commits to pay against complying documents. Collections are cheaper; letters of credit give the seller more security. Collections are commonly made subject to the ICC's Uniform Rules for Collections; ask your bank which rules its collection instruction states.
For a UAE seller, the honest risk is a Nigerian buyer who decides not to take up the documents, for example because prices fell, leaving a container in a Lagos port accumulating charges. For a Nigerian buyer, the risk is paying under D/P for documents that describe goods the seller did not actually ship as agreed; collections do not involve the banks checking the goods.
Make the documents match
Nigerian Customs and banks will check the collection documents against the Form M. Keep the following identical across the proforma, final invoice, bill of lading and Form M: buyer's name, description, quantity, value and Incoterm. If the bill of lading is "to order", it must be endorsed so that title can pass when the documents are released. A telex release defeats a collection, because the cargo could be collected without the documents; see telex release or original bill of lading.
Worked example
Example only. A Sharjah supplier sells $25,000 of auto parts to an Aba dealer on D/P terms. The supplier ships, lodges the original bill of lading, invoice and packing list with its bank, and the documents reach the dealer's bank in Lagos about a week later. The dealer pays $25,000 through the bank, which releases the documents, and the dealer's agent clears the container. If the dealer had refused, the supplier would still own the goods but would face finding a new buyer in Nigeria or paying to ship them back, plus port charges in the meantime.
Moving from collection to open account
Collections often work as a stage in a trading relationship. A UAE seller may start a new Nigerian buyer on D/P, move to D/A once several shipments have been paid on time, and later to open account, where the seller ships and sends documents directly and the buyer pays by transfer. Each step reduces bank charges and paperwork, and each step moves more risk to the seller. Agree in writing what would move the relationship back a step, such as a late payment.
What to check first
- Is the buyer's Form M opened with bills for collection as the payment mode?
- Has the seller's bank got a correspondent relationship with the buyer's Nigerian bank?
- Who pays each bank's charges? State it in the contract.
- What happens if documents are not taken up within a set time? Agree it before shipping.

Where Pryme fits
Collections run through trade banks. Where buyer and seller move to open-account terms after a few successful collections, a Pryme Business Account can receive USD with local details and invoicing keeps each shipment's invoice on record. Outside Nigeria, Pryme's activities are carried out through regulated partners.
Questions people ask
What is the difference between D/P and D/A?
Under D/P the buyer pays to receive the documents. Under D/A the buyer receives them by accepting a bill of exchange and pays on its maturity date.
Does the bank guarantee payment in a documentary collection?
No. The banks only handle the documents; they give no payment undertaking. A letter of credit is the option with a bank commitment.
Can a Nigerian importer pay by documentary collection?
Yes. Bills for collection is one of the Form M payment modes listed by Sterling Bank.
Is a documentary collection cheaper than a letter of credit?
Generally yes, because the banks take on less. The trade-off is less security for the seller.
