The structural problem in trade is timing. You pay your supplier before you sell the goods, and often long before your own customers pay you. The gap between cash out and cash in is the working-capital hole every importer lives in, and it is what caps how fast a trading business can grow.
Trade finance exists to bridge that gap. The African SME version of the market is thinner and more expensive than the version described in textbooks, but more of it exists than most business owners realise.
Map your cash cycle first
Before evaluating instruments, know the shape of your own gap:
- Day 0: deposit paid to supplier
- Day 30: production complete, balance paid
- Day 55: goods arrive at port
- Day 62: cleared and delivered
- Day 92: customer pays on 30-day terms
That is a 92-day cycle, of which you are funding the goods for the whole period and the balance for 62 days. If you turn over four times a year, your entire working capital is committed continuously.
The instruments below each attack a different segment of that line. Choosing the right one starts with knowing which segment actually hurts.
Purchase order finance
A lender advances funds against a confirmed customer order so you can pay your supplier.
Fits: you have a firm order from a creditworthy buyer but not the cash to fulfil it. Common for suppliers to corporates, government contracts, and large retail.
Requires: a genuine, verifiable purchase order from a buyer the lender considers good. The lender is underwriting your customer's credit more than yours.
Cost: expensive — often 2–4% per month in African markets. It is short-term bridging, not a financing base.
Watch: lenders often pay your supplier directly and take control of the receivable. You are trading margin and autonomy for the ability to take an order you otherwise could not.
Invoice discounting and factoring
You sell your receivables — invoices already issued to customers — at a discount for immediate cash.
Invoice discounting is confidential; you keep collecting. Factoring transfers collection to the factor, who chases your customers directly.
Fits: the tail end of the cycle. You have delivered, invoiced, and are waiting 30–90 days.
Requires: creditworthy customers and clean, undisputed invoices. Factors decline invoices with performance conditions attached.
Cost: typically 2–5% of invoice value depending on tenor and customer quality, plus fees.
Watch: distinguish recourse from non-recourse. Under recourse factoring, if your customer does not pay, you repay the factor — you have borrowed, not sold. Non-recourse transfers the credit risk and costs more. Many SMEs discover which they signed only after a customer defaults.
Factoring is more developed in Kenya, Nigeria, and South Africa than elsewhere on the continent, and there are dedicated receivables platforms in each.
Letters of credit and bank guarantees
Covered in depth separately, but in cash terms: an LC does not usually provide finance. Your bank will typically require cash cover or a credit line for the full amount, which freezes working capital rather than releasing it.
The financing variant is a usance (deferred payment) credit — the supplier ships and is paid at, say, 90 days after the bill of lading date. You get the goods now and pay later. This is genuinely useful, and it is what to ask for when a bank offers you an LC and you need funding rather than assurance.
Some suppliers will discount their own usance LC with their bank, receiving cash immediately while you still pay at 90 days. If your supplier can do this, a usance credit costs them little and solves your timing problem entirely. It is worth asking.
Supplier credit
The cheapest financing is often the supplier's own balance sheet. Open account terms — net 30, net 60, net 90 — cost nothing beyond whatever discount you forgo for early payment.
You will not get this on a first order. You may well get it on your fifth. It is one of the strongest arguments for concentrating volume with a small number of suppliers rather than always chasing the cheapest quote: payment terms are earned, and they are worth more than the 3% you save by switching.
Ask explicitly once you have a track record. Many buyers never do.
Distributor and stock finance
A lender finances inventory, secured against the goods themselves, often held in a controlled warehouse and released as you sell.
Fits: fast-moving goods where you need stock on the ground and turnover is predictable.
Requires: goods that hold value and can be independently valued and controlled. Collateral management arrangements are common.
Cost: cheaper than PO finance because the lender holds security.
Watch: you lose flexibility over your own stock, and storage plus collateral management fees are real. Model them into the margin.
Development finance and guarantee schemes
Frequently overlooked, and materially cheaper than commercial alternatives.
- Afreximbank provides trade finance lines across the continent, often through local partner banks.
- The African Development Bank operates trade finance programmes including guarantee facilities that let local banks lend where they otherwise would not.
- The International Trade Centre and various bilateral programmes run SME-focused facilities.
- National schemes exist in most markets — export-import banks, SME development funds, and central-bank intervention funds.
These rarely lend to SMEs directly. They work through partner banks, which is why the practical route is to ask your own bank which DFI-backed lines they participate in. Many relationship managers will not volunteer this.
Fintech and platform finance
The fastest-moving segment. Lenders underwrite on transaction data — platform trading history, mobile money flows, payment records — rather than on collateral and audited accounts.
Fits: businesses with digital transaction history but no property to pledge, which describes most African SME importers.
Requires: a data trail. This is a concrete reason to keep transactions on-platform and on the record rather than settling informally.
Cost: varies enormously. Some is competitive; some is extremely expensive credit with a modern interface. Always convert the quoted rate to an annualised figure before comparing. "3% per month" is roughly 43% a year compounded, not 36%.
Reading the true cost
Quoted rates are rarely comparable. Normalise everything:
Convert to an annual rate. Monthly and per-transaction rates hide their own size.
Include every fee. Arrangement, commitment, valuation, legal, insurance, collateral management. On short-tenor facilities, fees frequently exceed interest.
Account for tied-up cash. A facility requiring 30% cash margin is not financing 100% of the transaction.
Compare against the margin, not against zero. If financing costs 3% per month and your cycle is three months, it consumes about 9% of transaction value. On a 15% gross margin, you have given up 60% of your profit — but you have also done a transaction you otherwise could not, and built the track record that makes the next facility cheaper. That can be a good trade. It is a bad trade if it becomes permanent.
What lenders actually assess
Understanding the credit decision lets you prepare for it rather than react to it. Most trade finance underwriting looks at four things, roughly in this order.
The transaction, not the borrower. Good trade finance is self-liquidating — the goods being financed generate the cash that repays the facility. Lenders want to see a clear line from advance to goods to sale to repayment. A financing request that cannot show that line reads as a general working-capital loan, which is underwritten far more conservatively.
Your counterparties. Who is your supplier, and are they real? Who is your customer, and will they pay? For PO finance and factoring, your customer's credit matters more than yours.
Your track record. Completed transactions, on-time payments, and consistent volumes. This is why the transaction record you build early is an asset — it is literally the underwriting input.
Security and structure. Cash margin, goods as collateral, assignment of receivables, personal guarantees. In most African markets, expect personal guarantees from directors on SME facilities. Understand what you are signing; a personal guarantee survives the company.
Preparing an application
Have these ready before you approach anyone:
- Six to twelve months of bank statements, showing trading flow.
- A clear transaction summary — what you are buying, from whom, for whom, at what price, on what terms, with what margin.
- Supporting documents — the purchase order or contract, the supplier's proforma invoice, and any prior invoices with the same counterparties.
- Your landed-cost model, showing you understand duty, levies, freight, and financing cost. This single document distinguishes a serious applicant from a hopeful one more reliably than anything else.
- Registration and tax compliance documents, current.
The most common reason SME applications fail is not weak economics. It is that the applicant cannot evidence the transaction they are describing.
A realistic progression
Starting out: self-funded, small orders, escrow for protection. Build a transaction record deliberately, because it is the asset that unlocks everything else.
Some track record: supplier credit on repeat orders. Fintech working capital against platform history. Invoice discounting once you sell to creditworthy customers.
Established: bank facilities, usance letters of credit, DFI-backed lines through your bank. Meaningfully cheaper, and the reason it is worth building a formal banking relationship before you urgently need one.
The mistake to avoid is waiting until you need finance to start building the relationship and the record. Both take months. Open the conversation with your bank while you do not need them — that is when you have the most leverage and the least urgency.
