Delivery Note Book with Signed Copy and Invoice Follow-Up

Delivery Note Book is an offline app (one HTML file in a zip) for a trader, supplier or small distributor who sends goods out with a driver or lets customers collect. You write each delivery note once, print it, and then keep track of what happens to it: out on the road, delivered, signed copy back in the file, and invoiced.

The problem it removes: Delivery notes are signed on loose paper, the customer copy goes in a drawer, and weeks later nobody can find proof of delivery when a customer disputes an invoice. Some deliveries are never invoiced at all because nobody connected the note to a bill. This app keeps one numbered record per note and shows what is still open.

What is inside:

• Numbered delivery notes (DN number by year) with item lines, customer order reference, driver and site address
• Status board logic: Prepared, Out for delivery, Delivered, Part delivered, Returned, Cancelled, changed in one tap
• Accepted quantity per line, so a short delivery shows how many lines the customer did not take in full
• Follow-up page: signed copies missing (oldest first, with a WhatsApp message to the customer), delivered but not invoiced, part deliveries with a balance to follow
• A4 and A5 delivery note print with signature boxes, and a printable delivery register for any period
• Customers, items and drivers lists, with unsigned and not-invoiced counts per customer
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: traders, wholesalers, suppliers, caterers and workshops that deliver goods on a note and want proof of delivery and invoicing to be tracked without a full ERP.

What it is NOT: It does not hold stock levels, prices or invoices: it records what went out and whether the signed copy and the invoice number are on file. It does not store photos or signatures, it cannot be shared between several computers at once, and it is not a transport or customs document. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Verified by us: scripted tests in Chromium (156 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 1033 calculated values (25 randomised rows plus the example data) with 0 mismatches. Safari engine (WebKit): smoke test passed; Firefox: could not be launched. Not tested: Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
