A term sheet is on the table, and the data-room request comes back with a line item: contractor payment records, agreements and proof of payment for every contractor paid in the past two years. The founder’s finance stack has never had all three in one place. Contractors were paid ad hoc in USDT since the company’s first six months, back when a business bank account didn’t exist yet and a wire transfer meant a week’s wait and a fee nobody could fully explain.
Investors are testing whether the company can produce a document trail showing who was paid, for what, under what agreement, and whether that person was really a contractor rather than an unregistered employee. Founders who have this in order before diligence starts usually route contractor payments through a platform built for it — 4dev.com is one example built around keeping contractor agreements, invoices and payment records in one place, instead of scattered across bank statements, wallets and email threads.
How startups ended up paying contractors in USDT
Most startups don’t set out to pay contractors in stablecoins. It happens because the alternative is slower and more expensive at the exact stage when speed matters most. A founder needs a designer or an engineer this week; the company’s bank account is new or doesn’t exist yet; a wire to another country can take three to five business days and lose money to an exchange-rate margin nobody quotes upfront. The Financial Stability Board’s 2025 review of cross-border payment costs found the average total cost of a business payment sent internationally runs about 1.6% of the amount, with roughly 1.4 percentage points of that — the large majority — coming from the exchange-rate margin rather than a visible fee. That margin barely shrinks as the payment gets bigger: the same data shows it holding in the 0.7%-1.1% range across payment sizes, even as visible per-payment fees fall.
A contractor who accepts USDT gets paid in minutes, at a rate both sides can check against a public exchange rate, with no bank asking for the purpose of the transfer or holding it for review. For a two-person founding team paying three contractors in three countries, that’s a genuine operational reason. It also means nobody set up a contractor agreement template, an invoice numbering scheme, or a record of which wallet address belongs to which person — because that wasn’t the problem being solved in month two.
What due diligence asks about contractor payments
A data-room review of contractor payments is really three checks bundled together, and investors ask about all three whether the money moved by wire or by USDT.
The paper matches the payment. For every contractor: is there a signed agreement, an invoice referencing that agreement, and a payment that reconciles to the invoice’s amount and date? A reviewer who finds a payment with no invoice behind it, or an invoice with no signed agreement behind it, tends to treat the whole ledger as unverified rather than assume the missing piece is a formality.
The classification holds up. Most tests for worker classification look at substance, not at what the contract is titled: who controls the hours and the method of the work, whose equipment and systems get used, how integrated the person is into the core business, whether the arrangement is exclusive, how economically dependent the person is on this one client, and how long the relationship has run. A contractor who has worked full-time, exclusively, on company-issued equipment for two years looks like an employee to a regulator no matter what the agreement calls them — and a startup that can show it already thought this through looks prepared.
The tax forms are on file. A US company paying a US contractor collects a W-9; paying a non-US individual, it collects a W-8BEN, which expires at the end of the third calendar year after it’s signed and needs renewing on schedule. Without a valid form on file, the default is to withhold — 24% for a US payee under backup withholding, 30% for a foreign one — so a missing W-8BEN is an open tax question investors expect to see closed, well before an audit forces the issue. Compensation is sourced to where the work was physically performed, so a contractor who did all the work outside the US, and gave the company a valid W-8BEN, generally triggers no 1099 and no 1042-S. The company still needs that form itself on file as proof it checked.
Rebuilding the paper trail — agreements, invoices, payment proofs
Rebuilding a paper trail after the fact is possible. It is also weaker evidence than a trail built in real time, and a founder should say so plainly rather than present a reconstruction as though it always existed.
Start with the agreement. If a contractor has been paid for a year with nothing signed, the fix is a current, signed agreement stating the terms going forward, with a background section describing the actual history: when the work started, on what basis, what was paid so far. Backdating a signature isn’t a fix — a document dated today cannot claim to have been signed a year ago, and counsel on the other side of the deal will notice a document that was clearly produced after the fact but labeled otherwise.
Next, the invoices. Every payment needs an invoice it can be matched against: date, amount, currency, the work covered, the agreement it falls under. If a contractor was paid in USDT and never issued a formal invoice, retroactive invoices can be created and dated to match the actual payment dates, referencing the wallet transaction as the underlying record. What can’t be recreated honestly is an earlier document that never existed; what can be created is an accurate, clearly-dated record of a past payment.
Then the payment proof itself. For fiat, that’s a bank statement line. For USDT, it’s the transaction hash and the wallet addresses on both sides — and, if the payment ever touched an exchange to convert to or from fiat, the exchange’s own transaction record. A reviewer asking “show me this was paid” wants all three pointing at the same number, the same date, the same two parties.
For contractors based outside the US, two more items matter. Cross-border B2B services are usually taxed under a reverse-charge mechanism, where the liability sits with the buyer rather than disappearing — the paperwork exists either way, and a company that never generated it has a real gap, not an exemption. The invoice itself also needs to satisfy the contractor’s own country’s requirements, which differ: a Brazilian nota fiscal has no direct English equivalent, for instance, and a standard US-style invoice doesn’t automatically substitute for it. Where local rules expect the contractor to hold a self-employment registration, a copy of that registration on file closes a question before it gets asked.
Moving to a documented payout process, in crypto or fiat
The fix that actually prevents this from recurring is routing every contractor payment, whatever the rail, through one process that generates the paperwork automatically instead of relying on someone remembering to do it by hand.
That’s what a contractor-payments platform is for. 4dev.com, for example, is a Contractor Platform structured as a Contractor of Record: it contracts directly with each specialist on the client’s behalf, handling contractor engagements — not payroll, not employee benefits — across more than 150 countries. Each contractor works through a self-guided onboarding flow (sign up, accept tasks, complete account setup, receive documents) before the first payment goes out, so the agreement and the identity documents exist before the money moves. The company signs a single agreement with the platform that covers every contractor engaged through it, rather than negotiating one contract per person, and invoices generate per payment and export in one click: the difference between reconstructing a year of records under deadline and pulling a report. As a Contractor of Record, 4dev.com can legally pay a contractor in USDT with the closing documents behind that payment, and it also accepts crypto payments from the client side, alongside its usual fiat payout options.
Documenting the process is what makes the payment rail stop mattering. Once the agreement, the invoice and the payment all line up, it makes no difference to a reviewer whether the last one settled by wire or in USDT.
Two limits are worth knowing before leaning on a platform for this. 4dev.com itself has no Employer of Record product today — one is planned for 2027 — and it doesn’t run employee payroll; it operates on the contractor side only, so a company that later wants to convert someone to an actual employee still needs a separate EOR arrangement or a local entity for that person. And the FX-cost math from earlier doesn’t disappear just because a platform handles the paperwork: a business cross-border payment still carries roughly the same exchange-rate margin whether it’s sent manually or through a platform, so documenting the process and shopping for a lower FX margin are two separate jobs.
A pre-raise checklist
Before a term sheet turns into a data-room request, most of this can close in a week rather than during diligence itself:
- A signed agreement on file for every contractor, current if not historical, stating scope, payment terms and — where relevant — assignment of IP in the work product.
- An invoice for every payment made in the past two years, referencing the agreement it falls under.
- A payment record for every invoice: a bank statement line for fiat, a wallet address and transaction hash for USDT, an exchange record for any conversion in between.
- A W-9 on file for every US contractor, and a current W-8BEN for every non-US individual contractor, checked against the three-year expiry rather than assumed still valid.
- A one-line answer, per contractor, to whether this person could be read as an employee under a substance test — hours controlled, equipment used, exclusivity, duration. If the answer is uncomfortable, that’s worth fixing before diligence starts.
- One place — a shared drive, a registry, or a platform built for it — where all of the above lives per contractor, so producing the full set for one person, or for all of them, is a query rather than a research project.
FAQ
Does paying contractors in USDT itself look bad to investors? Not on its own. What investors react to is missing documentation — no signed agreement, no invoice, no way to reconcile a wallet payment to a person and a task. A USDT payment with a full paper trail behind it reads the same as a wire payment with a full paper trail behind it.
Do we owe 1099s for contractors we paid in crypto? It depends on who was paid and where the work was done, not on the currency. A US citizen or green-card holder is a US person for tax purposes even living abroad, and gets a 1099 once payments to them cross the reporting threshold — $2,000 per payee per calendar year from 1 January 2026. A non-US person who performed all the work outside the US, and gave the company a valid W-8BEN, generally triggers no 1099.
We can’t find the original agreement for a contractor we started paying a year ago. What now? Sign a current agreement today stating the ongoing terms, with a background section describing the actual history, then generate invoices dated to match the real payment dates and gather the payment proof — bank or wallet records — for every past payment. That’s a genuine reconstruction, and it will read as weaker evidence than a contemporaneous record would have. It’s exactly why the fix going forward is a documented process, built now, before the next raise turns it into an emergency again.
