Payment terms for B2B clients in the Gulf, and the real clock

Saudi law fixes the currency and prices the advance, then hands the number of days to the Regulations and your contract. That tells you where to spend the negotiation, and it is not on an interest clause.

Two companies can sign the same contract at the same price and have very different businesses six months later, because one read the payment clause and the other read the number. In the Gulf that gap is wider than in most markets, for a structural reason: much of the serious B2B revenue in Saudi Arabia and the UAE either is government spend or sits one layer below it, and government payment mechanics work nothing like a thirty day invoice between two private firms.

So this phrase is really two questions wearing one coat. One has a published legal answer you can read tonight. The other has no legal answer at all and is decided entirely by what you negotiate. Mixing them up is how a profitable contract becomes a cash flow problem.

The two different questions

When the client is a government entity, or a prime contractor paid by one, there is actual statute, published thresholds, and from early 2027 a new law. You can prepare for this.

When the client is a private company, there is no Gulf equivalent of a statutory payment period for ordinary commercial invoices. Terms are whatever the contract says, and the contract says whatever you agreed to before you understood the client's internal approval chain.

Almost all the frustration we hear sits in the second category while the advice people are reading was written about the first. If you are selling into the region for the first time, the sequencing problem comes earlier and is covered in expanding a B2B business to the Gulf without committing too early. This piece assumes you are past that and have a contract in front of you.

What Saudi law fixes, and what it hands to the contract

The Government Tenders and Procurement Law is published in full by the Saudi Ministry of Finance, and its payments chapter is shorter than people expect. Three articles matter, and all three change how you should price.

Article 64 fixes the currency. The value of contracts shall be paid in Saudi riyals, and an agency may designate other currencies in the tender documents only subject to the Ministry's prior approval. If you are a foreign supplier quoting in dollars, that is a tender-stage item, not something you raise after award, and the currency risk is yours unless it was approved up front.

Article 66 prices the advance. An agency may make an advance payment to the contractor in return for a bank guarantee of an equal value. That is the most misread line in the chapter. The advance exists, and it costs you a bank instrument for the full amount. A deposit here is not free cash, it is financing with a fee and a credit line behind it. If your plan for funding delivery was thirty percent up front, find out what your bank charges to issue that guarantee before you price the job.

Article 67 disappoints everybody. It says only that a contractor's entitlements shall be paid in accordance with the provisions of the Regulations. The number of days is not in the law. It is in the Implementing Regulations and, in practice, in your contract and the agency's own process. Anyone quoting you a statutory Saudi payment deadline from the law itself has not read the law.

The new law changes the incentive, not the clock

Saudi Arabia is replacing that law. Per Greenberg Traurig’s alert on the new law, the Council of Ministers approved a new Government Tenders and Procurement Law on 4 August 2026, and it comes into force 120 days after publication in the Official Gazette, which puts it at the start of 2027.

The change that matters most for cash is not a deadline either. It is an incentive: government entities must process amounts due to private-sector contractors within prescribed timelines before entering new contractual commitments. An entity that owes you money is constrained in its ability to award new work until it clears the backlog. That is a far better lever than an interest clause you would never enforce against a ministry, and it is worth knowing which of your receivables sit with an entity that has new awards it wants to make.

Three other numbers change who you are selling to:

• Direct purchase rises from SAR 100,000 to SAR 1 million. Much more work can be awarded without a full tender, which favours suppliers already known and registered over those who only watch tender portals.
• The delegation limit rises from SAR 10 million to SAR 50 million. Decisions you used to chase upward now stop lower down, so your champion may genuinely be the decision maker in a way they were not before.

Ministry of Finance pre-signing review also drops from up to 15 working days to four, and that one is a warning rather than a celebration. A shorter review removes the excuse for starting early, and starting early is the most reliable way to not get paid. Work performed before award, on a verbal instruction, or outside the contracted scope becomes a disputed claim rather than an invoice.

Private sector: the approval chain is the term

For a private Gulf client there is no period to look up. There is an internal process, and your real term is how long that process takes plus whatever you negotiated. So the useful discovery question is not what are your payment terms. It is: walk me through what happens to my invoice after I send it.

The answers that predict slow payment are easy to hear if you ask:

• The invoice needs a signature from someone who is not your buyer, and that person reviews in batches.
• Payment runs happen on a fixed day, so missing it by a day costs a month.
• A completion or goods-received certificate is required before the invoice is even accepted, and nobody owns issuing it.
• Your buyer cannot tell you who signs. This is the worst answer and it is common.

The third is the quiet killer. If the certificate is a gate, the person who issues it is part of your sale and should have been in the room. Discovery that stops at the buyer misses them, which is why the eight discovery questions that decide a deal includes process questions and not only need questions.

The four clauses that decide whether you get paid

• What starts the clock. Invoice date, receipt date, or acceptance date. If payment is due 60 days from acceptance and nothing says when acceptance must happen, you have agreed to an unbounded term.
• What counts as delivered. Milestones tied to your output are collectable. Milestones tied to the client's internal events, approvals, launches, or another vendor finishing are not milestones, they are hopes.
• Suspension, not interest. An interest clause gives you a claim you will not pursue against a client you want to keep. A right to suspend work on written notice after a defined overdue period changes behaviour, because it is cheap for you to exercise and expensive for them to absorb.
• Who the counterparty actually is. A regional subsidiary, a free zone entity and the group parent are three different balance sheets. The logo on the deck is not the signatory.

These are the same instincts that make a partner agreement hold up, and the clause-by-clause version is in the channel partner agreement clauses that matter. The client-services equivalent has the same structure in a different vocabulary: KF Agency wrote up the service contract clauses worth arguing over, in Arabic, which rewards a translation pass if you sell services into Egypt or the Gulf.

Price around the term instead of complaining about it

• Quote two prices. One at your standard term, one at theirs, the difference being your cost of money plus risk. Clients who cannot move the term can sometimes move the price, and they never volunteer this.
• Shorten the milestone, not the term. A 60 day term on monthly billing is a very different cash position from the same term on quarterly billing. The term is often immovable while the billing frequency is negotiable, and nobody asks.
• Charge for the guarantee. If an advance requires a bank guarantee of equal value, that fee is a line item in your cost, not a rounding error you eat.

Retainer against project, and what each does to cash flow, is worked through in B2B retainer versus project pricing. And because slow payment distorts forecasting more than it distorts revenue, receivables belong in the same conversation as forecasting B2B sales starting with slippage.

Honest limits

The legal detail here is Saudi government procurement, because that is where the published, citable rules are. It does not transfer to a private UAE client, a free zone entity, or to Qatar or Kuwait.

We also have no defensible figure for what private Gulf clients pay on average. Numbers in the 60 to 120 day range circulate widely and we cannot trace any of them to a published survey we have read, so we will not repeat them as fact. What we can say is that every supplier we have worked with who measured their own collection time found it longer than their contract said, and the gap was almost always the acceptance step rather than the payment step.

The last limit concerns the new law. It is approved and gazetted, but its Implementing Regulations are still pending, and that is where the actual payment timelines will live. Anyone giving you a day count for the new law today is guessing. Read your contract, find out who issues the certificate, and price the delay you can already see.
