This page is written by Flash, which makes one of the tools described here.
Flash is the CFO layer for compute operators: Bitcoin miners and GPU hosting businesses, side by side. This page is for Vast.ai hosts who need books that keep earnings, reported payouts and actual receipts apart.
See profit by site and machine group for your Vast hosting business. The Vast.ai connection is in early access. Overview: Flash for GPU operators. Payout listing: Vast.ai connection.
What a Vast.ai host needs from the books
Vast.ai pays hosts through Wise, PayPal or Stripe. Invoices are generated weekly on Fridays once a payout method is connected and the balance meets Vast.ai's threshold. An invoice marked Paid means Vast.ai has submitted the payout to the provider. It does not mean the money has finished processing there. Source: Vast.ai host payouts.
A GPU hosting business usually needs four records that stay distinct:
- Earnings for the period.
- Reported payouts from Earnings > Payout History (CSV or PDF).
- Receipts in Wise, PayPal or Stripe when the money lands.
- Site costs and hardware depreciation, so the month shows what the business kept.
Vast.ai is the marketplace source, not a general ledger. Fleet tools do not replace a reviewed monthly close.
Manual method: spreadsheet next to the source files
A small host can close a month without Flash:
- Export Payout History for the calendar month.
- Work Paid invoices. Leave Pending invoices for the next cycle.
- Match each Paid payout to the receipt in Wise, PayPal or Stripe by amount, reference and date. Note explained differences. Leave unexplained rows on a review list.
- Keep a machine register that maps each Vast.ai machine ID to one site. Pull per-machine earnings from Vast.ai's CLI or API, then roll them up by site. That view is a method you run yourself. Vast.ai pays the account, not each machine. Detail: track Vast.ai payouts per machine and per site.
- Subtract recorded power, hosting and network costs, plus book depreciation, from the earnings you and your accountant treat as income.
- Save the export, provider statements and match list with the month's files.
Matching steps: how Vast.ai host payouts work, and how to match them. Per-GPU formula: GPU hosting profitability per GPU.
What Flash does (early access)
Connect your Vast.ai host account in early access. Flash lists each payout Vast.ai reports. When the money lands, confirm it with the date and reference, and Flash keeps it in your audit history. If you've imported the receipt, Flash suggests the match by reference and amount.
Payouts are listed per connected Vast account. Flash does not group or split Vast.ai payouts by site or machine. Per-machine or per-site tracking remains a method the host follows.
Separately from the payout list, Flash brings earnings, recorded site costs and hardware depreciation into a monthly close with profit by site and machine group, as described on Flash for GPU operators. Review the month, lock it, and prepare journal entries for QuickBooks. Share a pack your lender can check, with each figure labelled by source.
The Vast.ai connection has only been tested on mock data so far. Treat it as early access until you have checked it against your own host records.
Limits
- Flash only has the payout as Vast.ai reports it. A USD receipt is in Flash only if you import or enter it.
- Flash does not sync bank transactions and does not reconcile full bank statements.
- Fees, currency conversion, and split or batched deposits are yours to record and confirm.
- Flash has no RunPod connection.
- Flash does not manage workloads, set rental prices or replace Vast.ai's host tools.
QuickBooks for a GPU hosting business
QuickBooks remains a strong general ledger for many GPU hosting businesses. Intuit documents project and job costing in QuickBooks Online Plus and Advanced, including income, labor, material and vendor costs by project. Source: QuickBooks project/job costing.
That project view helps when the reporting unit is a customer engagement. A Vast.ai host still needs marketplace earnings, reported payouts and receipts kept distinct, plus depreciation and a site view. The reviewed QuickBooks page does not state a native Vast.ai connection or GPU-machine mapping.
Flash works alongside QuickBooks. The live GPU page describes a direct QuickBooks integration: bring mapped QuickBooks costs into the close for review, then prepare journal entries after you review the month. Choose the useful life and accounting treatment with your accountant. Comparison: best accounting software for a GPU hosting business.
Worked month (example figures only)
Illustrative only. These are invented values, not current Vast.ai rates, a customer result or a forecast.
One connected Vast.ai account earned $4,200 in the month. Site A (machine group "rack-1") recorded $3,100. Site B (machine group "rack-2") recorded $1,100. Recorded power, hosting and network costs were $1,050. Book depreciation was $700.
- Earnings: $4,200
- Site costs: $1,050
- Book depreciation: $700
- Profit by site and machine group (combined): $2,450
Allocate costs and depreciation by site with a written method. In this example, $3,800 of payouts have been confirmed with a date and reference, and $400 is still waiting to land. Do not replace the $4,200 earnings record with $3,800, and do not count the receipt as a second $3,800 of revenue. Agree recognition with your accountant. This example does not assume Flash splits one Vast.ai payout across sites or machines.
Tax records (general information)
GPU rental income is generally taxable in the US whether or not a form arrives, and Vast.ai does not withhold tax for hosts. Keep monthly records of earnings, payouts, receipts, costs and in-service dates. Details: GPU rental income and taxes. Vast.ai also publishes a tax guide for hosts.
FAQ
What is Vast.ai host accounting software?
Software that helps a GPU hosting business keep Vast.ai earnings, reported payouts, receipts, site costs and hardware depreciation in a reviewed monthly close. Flash is one option for that compute-finance layer. Vast.ai's Payout History is the marketplace source, not a full set of operating books.
Does Flash connect to Vast.ai?
Yes, in early access. Flash lists each payout Vast.ai reports. When the money lands, confirm it with the date and reference, and Flash keeps it in your audit history. If you've imported the receipt, Flash suggests the match by reference and amount.
Does Flash split Vast.ai payouts by site or machine?
No. Payouts are listed per connected Vast account. Flash does not group or split payouts by site or machine. Profit by site and machine group is a separate reporting concept. Per-machine and per-site payout tracking is a method the host follows.
Can I use QuickBooks alone for a Vast.ai host business?
Evaluate QuickBooks Online Plus or Advanced for project and job costing. You still need a reviewed way to bring in Vast.ai earnings and payouts, confirm receipts, and keep depreciation and site costs. Flash prepares reviewed journal entries for QuickBooks; it does not replace the ledger.
Is Paid in Vast.ai the same as cash received?
No. Vast.ai marks an invoice Paid when it has submitted the payout to Wise, PayPal or Stripe, not when the money arrives. Source: Vast.ai host payouts.
Does Flash connect to RunPod?
No. Flash has no RunPod connection.
Is this tax or accounting advice?
No. This is general information only. Confirm treatment with a qualified adviser for your jurisdiction.
