CLEAR EXPECTATIONS
Before you get started.
Who is it for?
Small online product sellers who want manual, single-currency financial planning. It is not an inventory system, accounting platform or multi-store data integration.
Does it automatically import data?
No. The dashboard links to working sheets, but product, offer, monthly and cash modules use separate manual inputs. No platform connection or automatic bookkeeping is included.
What has been tested?
Internal checks evaluated formulas in a custom Python model. This is not independent financial audit or certified Excel/Google Sheets runtime compatibility. Final application testing remains a release requirement.
Can I use Google Sheets?
Google Sheets compatibility is not verified. Import, recalculation, protection, dates and charts require actual testing. We do not advertise it as supported.
Can I share it with clients?
The proposed license is internal use for one business. Sharing your own exported reports is allowed; redistribution or resale of the editable template is not. Final purchase terms will be displayed before checkout opens.
Where are the reviews?
There are no published customer reviews yet. We will only display genuine feedback with permission. Examples are fictional demonstrations, not testimonials.
Is this tax or financial advice?
No. Rates and assumptions are supplied by you. The toolkit does not establish exemptions, tax obligations or filing treatment, and no profit or savings are guaranteed.
