Multi-Year Crypto Accounting.

@nimiwebjuggler

As-salamu alaykum! My name is Muhammad Ali and I believe that the key to our success is your satisfaction. With over 10 years of experience in accounting, data analysis and processing, I have perfected my skills in handling large volumes of data, including crypto transactions, making me an ideal fit for your project. To ensure the highest level of accuracy and transparency, I propose we proceed with using raw CSV files as the single source of truth. I will meticulously import and reconcile the data from all the exchanges and wallet address histories you've provided into a year-by-year ledger. Employing specialist tools such as CoinTracking or Koinly, I will efficiently match the on-chain wallet activity with the corresponding exchange statements, taking great care in every aspect of cost-basis tracking and gain/loss calculations. Throughout this process, error handling is of utmost importance. As soon as any discrepancies are identified, I will vigilantly cross-reference with you to ensure we attain an accurate final summary that you can confidently hand straight to your tax preparer each year. In order to commence promptly, please provide me with the necessary file information so we can quickly dive into transforming your data into concise P&L reports. Looking forward to a successful collaboration!

Hi there! I understand how challenging it can be to reconcile multiple CSV exports and wallet histories across several years. Without accurate tracking, calculating realized and unrealized gains, cost basis, and end-of-year holdings can be error-prone, which is critical for tax reporting. I have strong experience handling high-volume crypto data using tools like CoinTracking, Koinly, CoinLedger, and Python-based processing scripts. I’ve reconciled exchange and wallet data, created year-by-year ledgers, calculated P&L, and generated summaries ready for tax submission, all while ensuring data accuracy and verifiability. My approach will be to import your CSV files, match wallet activity with exchange statements, handle any discrepancies, and calculate realized/unrealized gains. I’ll provide detailed annual summaries, error reports, and final reconciled ledgers that you can hand directly to your tax preparer.

Let me know if you’re interested & we can discuss it. Best Regards Ayesha

With my expertise in crypto accounting, high-volume data processing, and Python/Excel automation, I can take your CSV exports and wallet histories and turn them into fully reconciled, year-by-year reports that align on-chain activity with exchange statements. To implement this, I would import the CSVs into a robust reconciliation workflow, match transactions across wallets and exchanges using timestamps, amounts, and asset types, flag discrepancies for review, calculate realized/unrealized gains, cost basis, and generate clean P&L summaries ready for your tax preparer. I can execute this accurately and efficiently without issues, as I’ve handled complex multi-year, multi-exchange crypto reconciliations using both raw CSVs and APIs while ensuring all calculations are verifiable and audit-ready. Regards, Bor

Hi Carlos, I understand the complexity of your project involving multi-year crypto accounting and the importance of accurate reconciliation between on-chain wallet activity and exchange statements. My approach would involve meticulously reconciling the CSV exports with wallet address histories to generate detailed year-by-year ledgers. I would then calculate realised and unrealised gains/losses, track cost-basis, provide end-of-year holdings, and create concise P&L statements for each period. To ensure accuracy, I would utilize specialist tools like CoinTracking, Koinly, or CoinLedger and implement robust import processes, matching logic, and error handling mechanisms. Your data integrity is crucial, and I will work closely with you to gather any additional information needed for a seamless reconciliation process. With my experience in handling high-volume crypto data across various wallets and centralized exchange accounts, I am confident in delivering precise and reliable reports that can be directly provided to your tax preparer. I look forward to the opportunity to collaborate on this project and achieve your desired outcomes. Best regards, Taneem

I can turn your 2022–2025 CEX CSV exports + wallet histories into fully reconciled, tax-ready annual reports (ledger, holdings, cost basis, P&L, and a clean year-end summary for a tax preparer). Accuracy is my top priority. this is the same standard I require for my own reporting too. Approach: * Use your CSVs as the source of truth, API pulls only for verification * Flag and fix mismatches (duplicates, symbol changes, missing prices) * Output verifiable reports per year I can use Koinly/CoinTracking/CoinLedger (or Python reconciliation if needed) to ensure everything balances and is auditable.
