Short answer: Cross-border robot purchases are normally paid in stages tied to verifiable events — a deposit at order, a progress payment around completion or shipment, and a balance after delivery and acceptance. The percentages are negotiated case by case and set by the contract, not by any industry standard; what protects both sides is the alignment: each payment should follow evidence (a signed order, production records, shipping documents, a passed acceptance test) rather than the calendar. The transport side of the same timeline is covered in our guide to shipping robots internationally.
The milestone structure, and why it looks like that
Milestone payment exists because neither side can fully trust the other across a border, and both are right. The buyer's deposit funds the seller's production slot and long-lead components; the pre-shipment payment protects the seller against building a bespoke machine for a buyer who vanishes; the post-acceptance balance gives the buyer leverage until the machine demonstrably works. Deals go wrong when the stages detach from the evidence — large early payments against promises, or a final balance demanded before the acceptance test that our guide to FAT, SAT and acceptance testing describes. Read any proposed schedule by asking, at each stage: what will I be able to verify, and what will I hold if the other side stops performing?
Letters of credit vs wire transfers
The two common payment rails price risk differently. A wire transfer is simple and cheap, and protects nobody: once sent, recovery depends on the relationship and the courts. A letter of credit puts a bank between the parties — the seller is paid against conforming documents (invoice, transport documents, certificates the credit specifies), and the buyer pays for goods the documents describe. The discipline is in the documents: a letter of credit pays against paper, not against the machine, so the specified documents must include the evidence that matters — inspection or FAT certificates, packing lists, certificates of origin — and the expiry dates must survive realistic shipping delays. For established relationships and smaller amounts, transfers against milestone evidence are common; for first deals and large systems, the credit's cost is usually the cheapest insurance in the transaction. Neither instrument replaces vetting the counterparty.
Currency, timing and the quiet costs
Cross-border schedules carry financial friction that belongs in the negotiation, not in a surprise: exchange-rate movement between deposit and balance (decide whose currency the contract is in, and consider that a milestone months away is a small currency position), bank charges on both sides and who bears them, and the working-capital cost of the payment timing itself — a long gap between the shipment payment and the acceptance balance is financing the seller provides or withholds, and it is priced whether or not it appears as a line. State the mechanics plainly: which bank charges, which value dates, what counts as 'payment received' for milestone purposes.
Retention, warranty and the last payment
The final balance is the buyer's main quality lever, and its release should be tied to defined events: delivery, installation, passed site acceptance, and clearance of the punch list — with a retention held where the contract provides for one, released after an agreed period of satisfactory operation. Connect the money clauses to the warranty clauses deliberately: warranty start should follow acceptance rather than shipment (a machine can spend its warranty on a ship and in a warehouse otherwise), and the documents that close the deal — manuals, program backups, spare lists — should be listed as acceptance deliverables, so the last payment buys the whole machine, including its paper.
First deals: shrink the risk before you shrink the price
With a new overseas supplier, the safest first transaction is a smaller one: a single machine or cell, standard configuration, milestones verified by an inspection agent or a witnessed factory test, and payment instruments that do not require trusting anyone's goodwill. References from the supplier's other export customers, in markets with similar distance and legal distance, are worth more than a discount. If the first deal performs — machine, documents, payments, service — the second can carry larger amounts on simpler terms. Cross-border trust is built out of completed milestones; the contract's job is to make the first few easy to complete and easy to verify.
Frequently asked questions
What payment structure is normal for an overseas robot purchase?
Milestone payments tied to verifiable events — a deposit at order, a progress payment around completion or shipment, and a balance after delivery and acceptance. The exact split is negotiated per contract; there is no universal standard percentage.
Should I pay by letter of credit or wire transfer?
Transfers are simpler and cheaper but protect neither side. A letter of credit pays the seller against conforming documents through a bank — worthwhile for first deals and large systems, provided the required documents include the evidence that matters, such as test and inspection certificates.
When should the final payment be released?
Against defined events: delivery, installation, passed site acceptance and punch-list clearance, with any retention released after the agreed period of satisfactory operation. Warranty should start at acceptance, not at shipment.
How do I reduce risk on a first deal with a new overseas supplier?
Start smaller: one standard machine, witnessed factory testing or third-party inspection, milestone payments against documents, and references from the supplier's other export customers. Trust is built from completed, verified milestones.
