Everything on sostren.com and in our products is general information and organizational tooling. It is not tax, legal, accounting, medical, financial, insurance or career advice, and using it does not create a professional relationship with Sostren.

Etsy & Shopify Seller Tax Kit

The workbook and guide are educational bookkeeping tools. They are not a substitute for a CPA, enrolled agent, tax attorney or other qualified tax professional. The quarterly tax helper produces a simplified, rough estimate. Tax rules change and depend on your situation; figures reflect our understanding of US federal rules for the 2026 tax year at the time of writing and may become outdated. State rules are not covered. Please have a qualified professional review your return. Not affiliated with or endorsed by Etsy, Shopify or the IRS.

Aging Parent Caregiver Binder

The binder is a personal organizing tool. It is not medical or legal advice, nor financial or insurance advice. Always follow the guidance of doctors, pharmacists and other healthcare providers. Legal document requirements vary by state; consult a qualified attorney. Medicare information was checked against Medicare.gov and CMS in October 2026 and may change; confirm with Medicare.gov, 1-800-MEDICARE or your State Health Insurance Assistance Program (SHIP). In an emergency, call 911.

ATS-Proof Job Search Kit

Templates and guidance are general career information. No resume, template or tool can guarantee interviews or job offers. Applicant tracking systems vary by employer. Review any AI-generated text for accuracy before using it.

No guarantees

We work hard to keep our products accurate, but we make no warranty that they are complete, current or error-free. You are responsible for how you use them. Questions: hello@sostren.com
