PRIVATE DEPOSIT MATH · NO ACCOUNT

Make the deposit and balance add up.

Turn a total, amount due now, and observable balance trigger into one clear payment schedule. The calculation stays in this browser and creates no receipt.

CHECK THE SPLIT

Keep it public: do not enter a customer name, email, address, private invoice link, card data, or secret.

01 · TOTAL

Name the whole price

A deposit is easier to interpret when the complete custom-order price and currency appear beside it.

02 · SPLIT

Show both amounts

The amount due now plus the remaining balance should equal the total exactly.

03 · TRIGGER

Use an observable event

Write what makes the balance due: proof approval, production start, dispatch, delivery, or a fixed public date.

DEPOSIT QUESTIONS

What the arithmetic does—and does not—settle.

Should a deposit and remaining balance equal the total price?

When the schedule represents the whole agreed price, the amount due now plus the remaining balance should equal the stated total exactly. Record any later scope change or extra separately.

When should the remaining balance be due?

Use an observable event or public date: final-proof approval, production start, dispatch, delivery, or a fixed date. Avoid vague triggers such as “later” or “when complete.”

Does paying a deposit automatically make it non-refundable?

A payment schedule does not decide refund or cancellation rights. Record the exact treatment of the deposit separately, including what happens before approval, after work starts, and after a delay. Applicable law may add rights beyond the written promise.

Does this checker upload or store the figures?

No. The calculation runs in this browser and creates no account, upload, or receipt. A public receipt exists only if a merchant later reviews the separate form and chooses to seal it.

What does an OfferChecksum receipt prove?

Verification shows that the stored public commercial terms still match the content used to create their SHA-256 checksum. It does not prove identity, authority, consent, payment, performance, fairness, or legal enforceability.

BEFORE MONEY MOVES

Check the rest of the promise.

Price is one of six topics. Delivery, scope changes, refunds, and cancellation can matter just as much.
