Who this service is for
- Freelancers with straightforward receiptsDesigners, developers, writers, and consultants who invoice clients or receive platform payments and want their books organized monthly.
- Single-owner online shopsSellers with product sales, shipping costs, and payment-processor fees who need clear categorization and quarterly tax estimates.
- Sole proprietors without employeesIndependent contractors filing Schedule C who handle their own invoicing and want a bookkeeper to track expenses and prepare returns.
- Anyone tired of April chaosIf you've ever spent the week before the deadline sorting receipts and guessing at categories, monthly bookkeeping eliminates that scramble.
This service is not for businesses with employees (we do not handle payroll), partnerships, S corporations, or anyone needing representation before federal or state tax authorities.
What we do, and what stays with you

- Track business expenses by category and reconcile them to bank statements
- Calculate quarterly estimated tax based on your current profit and deductions
- Prepare Schedule C (business profit and loss) and Form 1040 for annual filing
- Answer questions about record organization and federal forms during video calls
What remains your responsibility

- Tax-planning decisions, retirement contributions, and entity-structure choices
Bookkeeping that makes tax season routine
Most freelancers and sole proprietors wait until April to sort through a year of receipts, bank statements, and invoices. By then it's hard to remember which dinner was a client meeting and which software subscription expired in July. Sato Seed solves this by reviewing your records every month while the context is fresh.
We categorize receipts and expenses as they happen, so your books stay current and your quarterly estimates reflect real numbers. When it's time to file your annual return, the Schedule C is already built from twelve months of checked data. You sign off on the completed forms and send them to the tax authority; we never file or represent you directly, so you stay in control of what gets submitted.
- Monthly categorization keeps your records current and accurate
- Quarterly estimates help you avoid surprises and underpayment penalties
- Annual filing becomes a check, not a scramble

Questions about bookkeeping and tax prep
Honest answers about what we do, what we do not do, and how the service works.
FAQWhat should I expect each month?
You send bank statements, receipts, and invoices by the fifth of the month. We categorize everything, reconcile it to your bank, and send you a profit-and-loss summary by the tenth. Before quarterly deadlines, we also send your estimated tax amount.
Who is this not for?
We work with sole proprietors who have straightforward receipts and expenses. If you have employees, multiple business entities, inventory accounting, or need representation before the tax authority, we are not the right fit.
What is included in the monthly service?
Monthly categorization of receipts and expenses, quarterly estimated tax calculation, annual Schedule C and Form 1040 preparation, and video calls to check your books and answer procedural questions.
What we deliberately leave out
We organize records and prepare forms; some tasks require a licensed professional or stay with you.
- No tax-planning or strategy adviceWe calculate what you owe based on your receipts and expenses, but we do not advise on deductions, retirement accounts, or entity structure.
- No federal representationIf you receive a notice, audit letter, or request for additional information, you handle the reply or hire a licensed representative.
- No payroll for employeesThis service covers sole proprietors; if you have employees, you need payroll software or a service that files employment-tax forms.
- You approve and file the returnWe prepare the forms and calculate the numbers, but you check, sign, and submit the return to the tax authority; we never file on your behalf.
