ABOUT DUEWISE

Duewise is the branding used in the delivered invoice toolkit from LintHead Restorations. The workbook, reminder text file and buyer guide retain that name.

HOW IT WORKS

Enter the invoice number, client, issue date, amount and payments received in the yellow input cells. Review Settings for default payment terms and the monthly simple late-fee rate. The dashboard summarizes recorded invoices and balances.

Due date is the issue date plus the configured term days. Outstanding balance is invoice amount less payments received, floored at zero. Overdue days apply when an unpaid balance remains. The optional simple late-fee estimate uses unpaid balance × monthly rate × overdue days ÷30; it does not compound. Date-dependent results use the spreadsheet application's current date.

OPENING AND USE

Supplied as an XLSX workbook, a plain-text template file and a PDF guide in one ZIP. Open the workbook in compatible spreadsheet software, save a working copy and check the example results before real use. For Google Sheets, import a copy and check formulas, dates and layout before use.

SCOPE

This is a manual spreadsheet template. It does not create or send invoices, process payments, connect to accounting software or banks, or send reminders automatically. Edit the reminder wording and send messages yourself. Only charge a late fee when the customer's agreement and applicable law permit it.

One-time digital download for the buyer's business. No subscription or physical shipment. Back up the workbook and keep private client information secure. Duewise does not provide legal, accounting or tax advice. Support details are in the included buyer guide.
