Export payment methods and how to secure a sale

Q: What are the export payment methods?

Four main methods, from safest to riskiest for the seller : advance payment (deposit + balance), the letter of credit (a bank pays against documents), documentary collection (documents released against payment or acceptance) and the open account (delivery then payment on credit).

Q: Which payment method is safest for the seller?

Advance payment (deposit + balance before shipment) is the safest, followed by the confirmed letter of credit , where a Tunisian bank undertakes to pay against compliant documents. The open account is the riskiest for the seller.

Q: What's the difference between a letter of credit and documentary collection?

In a letter of credit , a bank undertakes to pay the seller against compliant documents. In a documentary collection , the bank guarantees nothing : it simply forwards the documents and releases them against payment (D/P) or acceptance (D/A). The LC is safer but more expensive.

Q: What is open account payment?

The seller ships and invoices , the buyer pays afterwards (30, 60 or 90 days). It's the method most favourable to the buyer and the riskiest for the seller: to be reserved for established clients, ideally covered by COTUNACE credit insurance .

Q: What's the difference between D/P and D/A?

In D/P (documents against payment) , the buyer pays to receive the documents and the goods. In D/A (documents against acceptance) , they receive the documents against a promise to pay at maturity (accepted draft). D/A is riskier: no bank guarantees final payment.

Q: How do you secure a sale to a new client?

Require a deposit + balance or a confirmed letter of credit , and don't grant credit from the outset. You can also cover the receivable with COTUNACE credit insurance (usually 80-90% of the unpaid amount). See the COTUNACE guide.

Q: Is a letter of credit always necessary?

No. It's justified for large amounts or little-known buyers . For a reliable, long-standing client, a documentary collection, or even an insured open account, may be enough — cheaper. The right choice depends on the real risk.

Q: Is documentary collection cheaper than an LC?

Yes, generally: documentary collection generates fewer bank charges than a letter of credit. But it offers fewer guarantees — no bank undertakes to pay. It's a cost/security trade-off to make according to your trust in the buyer.

How do you get paid on export? The 4 payment methods

Short answer: there are four main ways to structure an international payment, from safest to riskiest for the seller: advance payment (deposit + balance before shipment), the letter of credit (a bank undertakes to pay against documents), documentary collection (the bank releases the documents against payment or acceptance) and the open account (you deliver, the buyer pays afterwards, on credit). The safer a method is for the seller, the less safe it is for the buyer — and vice versa.

For a Tunisian olive oil exporter, the right payment method depends on who the buyer is (known or not), on their country (political risk, currency transfer) and on the commercial balance of power. The banking acronyms (LC, documentary collection, D/P, D/A, UCP 600…) are defined in the glossary.

The export payment risk ladder

The same amount does not carry the same risk depending on the method chosen.

Payment method	Security for the SELLER	Security for the BUYER	When to use
Advance payment (deposit + balance)	★★★★★ Maximum	★ Low	New client, high-risk market
Confirmed letter of credit	★★★★★ Very high	★★★ Medium	Large amount, buyer little known
Unconfirmed letter of credit	★★★★ High	★★★ Medium	Trusted buyer/bank
Documentary collection (D/P)	★★★ Medium	★★★ Medium	Moderate trust relationship
Documentary collection (D/A)	★★ Limited	★★★★ Good	Reliable client, credit granted
Open account	★ Low	★★★★★ Maximum	Long-standing established client

Indicative benchmarks, to be adapted to the real risk of each buyer and each country. A sale not paid in advance deserves a layer of security (confirmed LC or credit insurance).

Key takeaway: you're not looking for "the best method" in absolute terms, but the one that balances security and competitiveness for a given transaction. A first container to a high-risk market is paid in advance or by confirmed LC; a long-standing client can move to open account.

Sidebar: buyer side / seller side

The payment method is a slider between two opposing interests.

Angle	What the payment method changes for you	Reflex
Buyer (importer)	Paying in advance ties up your cash; open account favours you	Propose an LC as a credible compromise
Seller (exporter who sells)	The method sets when and whether you'll be paid	Never ship a first container on open account
Exporter (Tunisia operations)	The method drives the documentary file and the domiciliation	Align documents and foreign-exchange terms from the contract onward

Contract drafting rule: the payment terms must be spelled out in black and white (method, deposit %, due date, currency, security mechanism). A verbal agreement has no value in the event of a dispute.

The 4 methods in detail

1. Advance payment (deposit + balance)

The safest for the seller. Common scheme: deposit on order + balance before or against shipment. A prudent practice is a 30% deposit on order, balance against documents (or by confirmed LC).

Seller's golden rule: never ship a container without a firm order + significant deposit. It's the basic protection of any new business flow.

2. Letter of credit (documentary credit)

A bank undertakes to pay the seller against strictly compliant documents. Very strong security, especially in the confirmed version by a Tunisian bank. It's the go-to tool for large amounts or little-known buyers — detailed in the letter of credit guide.

3. Documentary collection (documentary settlement)

The seller's bank forwards the documents to the buyer's bank, which only releases them against:

D/P (documents against payment): the buyer pays to obtain the documents (and therefore the goods). Medium security.
D/A (documents against acceptance): the buyer obtains the documents against a promise to pay at maturity (accepted draft). Less safe: the bank does not guarantee payment, unlike the LC.

Documentary collection is cheaper than an LC, but offers fewer guarantees: no bank undertakes to pay, it merely handles the documents.

4. Open account

The seller ships and invoices, the buyer pays afterwards (at 30, 60, 90 days). It's the method most favourable to the buyer and the riskiest for the seller. To be reserved for long-standing established clients — and ideally covered by COTUNACE credit insurance.

Adding a layer of security

Two mechanisms combine with the payment method to reduce the risk of non-payment:

LC confirmation: a Tunisian bank undertakes to pay even if the issuing bank defaults — it neutralises the foreign bank and country risk.
Export credit insurance (COTUNACE): it compensates the seller in the event of non-payment, usually up to 80-90% of the receivable, after buyer approval. It's particularly useful for open account or D/A sales, where no bank guarantees payment. See the COTUNACE guide.

Tip: the payment method and securing the sale are not mutually exclusive. An open-account sale insured by COTUNACE can be more competitive than an LC, while remaining under control.

Mistakes to avoid with export payments

Delivering a first container on open account: that's handing your goods on credit to a stranger.
Confusing documentary collection with a letter of credit: collection merely handles the documents, no bank guarantees payment.
Accepting an unconfirmed LC on a high-risk market: the foreign country/bank risk stays on you.
Forgetting foreign-exchange risk: invoicing in a foreign currency exposes you to fluctuation; to be hedged or invoiced in a currency you control.
Not writing the payment terms into the contract (deposit, due date, currency, security).
Neglecting the domiciliation and repatriation of proceeds required by Tunisian foreign-exchange regulations.
Believing a "safe" method dispenses with a perfect documentary file: both the LC and the collection rely on compliant documents.

Golden rules

Match the method to the risk: the more uncertain the buyer/country, the higher you climb the ladder (advance, confirmed LC).
First business flow: deposit + balance, or confirmed LC. Never open account from the outset.
Write the payment terms into the contract (method, %, due date, currency, security).
Combine payment method and layer of security (LC confirmation, credit insurance).
Anticipate foreign exchange and the domiciliation/repatriation obligations for proceeds.
A perfect documentary file conditions collection, whatever the method.

What is open account payment?

The seller ships and invoices, the buyer pays afterwards (30, 60 or 90 days). It's the method most favourable to the buyer and the riskiest for the seller: to be reserved for established clients, ideally covered by COTUNACE credit insurance.

What's the difference between D/P and D/A?

In D/P (documents against payment), the buyer pays to receive the documents and the goods. In D/A (documents against acceptance), they receive the documents against a promise to pay at maturity (accepted draft). D/A is riskier: no bank guarantees final payment.

How do you secure a sale to a new client?

Require a deposit + balance or a confirmed letter of credit, and don't grant credit from the outset. You can also cover the receivable with COTUNACE credit insurance (usually 80-90% of the unpaid amount). See the COTUNACE guide.

Is a letter of credit always necessary?

No. It's justified for large amounts or little-known buyers. For a reliable, long-standing client, a documentary collection, or even an insured open account, may be enough — cheaper. The right choice depends on the real risk.

Do you need a deposit to export olive oil?

It's strongly recommended for a new business flow. A prudent practice is a 30% deposit on order, balance against documents (or by confirmed LC). Never ship a container without a firm order and a deposit.

How do you manage foreign-exchange risk?

Invoicing in a foreign currency exposes you to fluctuation between order and payment. You can invoice in a currency you control, hedge the risk (forward exchange) or shorten the payment term. Tunisian regulations also require the domiciliation and the repatriation of proceeds — to be verified with your bank.

Is documentary collection cheaper than an LC?

Yes, generally: documentary collection generates fewer bank charges than a letter of credit. But it offers fewer guarantees — no bank undertakes to pay. It's a cost/security trade-off to make according to your trust in the buyer.

Can you combine a payment method and credit insurance?

Yes, and it's often recommended. An open account or D/A sale can be covered by COTUNACE (usually 80-90% of the receivable). This lets you offer attractive commercial terms while keeping the non-payment risk under control.

Which payment method should you choose for a first export?

For a first transaction to a little-known buyer: deposit + balance or confirmed letter of credit. These two methods offer the best security for the seller. Reserve documentary collection and the open account for established trust relationships.
