What the close keeps distinct
Every figure shows where it came from: pulled from an exchange, imported from your files, or declared by you.
- From exchange. Pulled from a connected exchange account.
- Imported. Imported from a CSV file you uploaded.
- Declared. Entered by you. Not independently verified.
Illustrative source labels. Recorded costs and fleet data are declared, not independently verified.
The illustrative month
Sample account, August 2026. Revenue at receipt. The company figure in the last column also deducts the $400 overhead. Site rows do not.
| Site | BTC | Revenue at receipt | Site cash costs | Profit after costs | After depreciation |
|---|---|---|---|---|---|
| North site | 0.224 | $18,204 | $10,300 | $7,904 | $5,971 |
| South site | 0.138 | $11,204 | $8,200 | $3,004 | $1,754 |
| Hosted fleet | 0.097 | $7,905 | $7,100 | $805 | $472 |
| Unallocated overhead | None | $400 | Not in site profit | minus $400 | |
| Company | 0.459 | $37,313 | $25,600 | $11,713 | $7,797 |
North site receipts are From exchange: 8 payouts pulled from your connected Kraken account, not Braiins Pool. South site receipts are Imported: 6 payouts imported from south-wallet-aug.csv. Hosted fleet receipts are Imported: 5 payouts, valued at receipt. The sample names no file for those five. Site cash costs are Declared, from the costs you file. The $400 is company cash overhead, not allocated to a site, and not in site profit.
Derived from the sample: $1,458 + $475 + $1,250 + $333 = $3,516, and $37,313 minus $25,600 minus $3,516 minus $400 = $7,797. Fully loaded costs are $29,516. The BTC column sums to 0.459. North is the strongest site. Hosted fleet's older machines leave $472 after depreciation. A price scenario elsewhere on that page uses a selected sample price, not this close. Revenue is valued when received, not at this reference price.
Book depreciation on the sample
Straight-line, book basis, from the fleet register on the sample.
| Group | Site | Units | Cost | In service | Life | Monthly charge |
|---|---|---|---|---|---|---|
| S21 XP | North site | 14 | $70,000 | Jan 2026 | 48 months | $1,458 |
| S21 Pro | North site | 6 | $22,800 | Mar 2026 | 48 months | $475 |
| S21 | South site | 20 | $60,000 | Oct 2025 | 48 months | $1,250 |
| S19j Pro | Hosted fleet | 20 | $12,000 | Feb 2024 | 36 months | $333 |
| August charge | 60 | $164,800 | Straight-line | $3,516 |
August journal entry preview, balanced: depreciation expense debit $3,516, accumulated depreciation credit $3,516. Review before posting to QuickBooks. Use the charges shown.
Break-even on the sample
A site's costs for the month divided by the Bitcoin it produced. Flash shows energy, cash and full-cost break-even with depreciation when the inputs are complete. Prices below are per Bitcoin, as shown on the sample.
| Site | Energy | Site cash | Full cost |
|---|---|---|---|
| North site | $35,938 | $45,982 | $54,612 |
| South site | $49,638 | $59,420 | $68,478 |
| Hosted fleet | $60,825 | $73,196 | $76,629 |
| Company | $45,316 | $55,773 | $64,305 |
Derived from the sample: company costs behind that row are $20,800, $25,600 and $29,516, and dividing by 0.459 BTC rounds to the prices shown. Site cash and full prices match the same way. Energy by site is not shown. $81,300 is a reference price, not the receipt value. For your own inputs, use Flash's Bitcoin mining calculator.
Walk the month
1. Bring in the Bitcoin
Connect Kraken, Coinbase, Coinbase Prime, Gemini, Braiins Pool, OCEAN Pool, NiceHash and your on-chain wallets, or import files from any other pool or exchange.
Braiins Pool connects directly with a read-only API token. OCEAN Pool connects read-only through your public Bitcoin mining address. NiceHash connects mining earnings and wallet activity, including deposits, trades and withdrawals. Direct exchange connections for Kraken, Coinbase, Coinbase Prime and Gemini are live too. Luxor and Foreman work through their CSV exports, imported with saved file definitions. Pool earnings, payouts and the balance still at the pool, checked at close.
Export steps: Braiins Pool and Luxor payouts to QuickBooks and NiceHash to QuickBooks.
2. Value each payout when received, and attribute it to a site
Map payout addresses to sites and keep unmatched activity visible for review. That is deposit-address-to-site attribution.
3. Add the costs you file
Add power and hosting, and company overhead you do not allocate to a site. Bring mapped QuickBooks expenses into the close for review. QuickBooks costs mapped for review and allocation by site.
4. Book depreciation
Flash runs straight-line book depreciation from the fleet register you record: units, cost, in-service date and useful life. It builds the journal entry for you to review. The useful life and tax method are your accountant's call. Every machine depreciated on a schedule, with journal entries ready to review and post to QuickBooks. See how to depreciate ASIC miners.
5. Review profit and Bitcoin break-even by site
Your break-even for every site and every group of machines: on energy alone, on site cash costs, and fully loaded with depreciation. Machine counts, running units and uptime are the fleet data you record.
6. Lock the month
Lock a month before sharing it. Later changes are recorded as corrections. Reviewed and locked. The sample's close history is August 2026, Version 1, Locked. A correction recorded Sep 4, 2026 says: Site cost classification corrected. Original close retained.
7. Hand the reviewed month on
Review the month, then export to QuickBooks or share a lender pack. Your accountant can review for free. Invite them with read-only access. Each locked month produces a lender pack: revenue and break-even by site, fleet and costs, holdings, and every figure labelled with its source. It's fingerprinted, so anyone can confirm it hasn't changed since you sent it. We shaped it with lender feedback. See lender-ready reporting for Bitcoin miners. Connect your data, review the result with your accountant and close the month for free. Choose a paid plan when you are ready to export to QuickBooks or share a lender pack.
8. FIFO cost basis, only as stated
FIFO cost basis and realized gains on disposals. Gains on Bitcoin sales stay separate. Check site costs, depreciation and Bitcoin cost basis, then post the entries. Keep the source behind every figure. How a lot is tracked is in FIFO cost basis for Bitcoin holdings.
Month-end checklist, with or without Flash
A bitcoin mining month end accounting checklist you can run with or without Flash. Tick a line only when you can point to a source.
- List each receipt with its date, BTC, and whether it was pulled from an exchange, imported, or entered by you.
- Value each payout when it was received.
- Attribute it to a site. Keep unmatched activity visible for review.
- File power and hosting by site. Leave unallocated overhead out of site profit.
- Bring mapped QuickBooks expenses into the review.
- Book straight-line depreciation from units, cost, in-service date and useful life. Agree useful life and tax method with your adviser.
- Review profit after costs and after depreciation, plus energy, site cash and full-cost break-even.
- Lock the month. If you change it later, record a correction and keep the original. Then hand off reviewed entries, or a pack your lender can check.
Questions
What is a Bitcoin mining monthly close?
A month-end review that values each payout when received, attributes it to a site, includes filed costs and straight-line book depreciation, and shows profit and break-even by site. Later changes are recorded as corrections, and the original close is retained.
Where did this sample's North receipts come from?
From a connected Kraken account, labelled From exchange, not from Braiins Pool. South and the hosted fleet are labelled Imported, as the table describes.
How is a payout valued and assigned to a site?
Value it when it was received. Map payout addresses to sites and keep unmatched activity visible for review.
How does depreciation enter the close?
Flash builds the journal entry from the fleet register for you to review. The useful life and tax method are your accountant's call.
What is energy, site cash and full-cost break-even?
A site's costs for the month divided by the Bitcoin it produced, shown for energy, site cash and full cost when the inputs are complete.
What do you hand off after the lock?
Reviewed journal entries to post to QuickBooks, read-only access for your accountant, and a pack your lender can check.
Are these figures a customer result or a Bitcoin price forecast?
No. The label under the title applies: invented figures, not a customer result, not a Bitcoin price forecast, not tax advice.
