Sure, lay out the terms and I’ll run them through my spreadsheet. No room for ambiguity.

Clause 1 is acceptable but you need to specify whether the 30 % is due per shipment or on the total contract value. Clause 2 should state that the 90‑day window starts from the invoice date, not the contract signing. Clause 3 “full ownership” must include the consequences of a default – is it a forfeiture or a return obligation? Clause 4 2 % per month is fine, but note whether it compounds and whether it’s a penalty or interest; the wording should be precise. Clause 5 “minimum quarterly volume 500 units” must be per calendar quarter, not cumulative over the year. Clause 6 auto‑renewal requires that the 60‑day notice be given before the end of the current term, and it should apply to both parties to avoid unilateral cancellation. All other terms are structurally sound.

All clauses now align. Add a delivery schedule to tie the 30 % to a specific shipment date, and require the contract to be in writing and signed by both parties. That's it.
