Recurring Cleaning Contract Visit and Monthly Billing Tracker

Recurring Cleaning Contract Visit and Monthly Billing Tracker is an offline app (one HTML file in a zip) for a cleaning company with monthly contracts such as offices, clinics and building lobbies. Each contract has a monthly fee and a number of visits a month. You log every visit as Done, Missed by us, Client cancelled or Rescheduled. At month end the app makes the draft bills from the visit log.

The problem it removes: Monthly visits are billed from memory. Some are missed and nobody notices until the client complains, and a missed visit is billed in full. This app shows how many visits each contract still owes this month, credits the visits you missed if the contract says so, and lists the contracts that have not been billed for last month.

What is inside:

• Contracts with client, site, monthly fee, visits per month, start and end dates, status and a credit-missed-visits option
• A visit log with status Done, Missed by us, Client cancelled or Rescheduled, the crew and a note
• Visits still owed this month for each contract, and a warning when few days are left in the month
• One button that creates last month's draft bill for every active contract that has not been billed yet
• A bill with visits planned, done and missed, a credit for visits missed by us, the amount, the invoice number and the paid date
• A printed visit statement per bill, a list of unpaid bills with a WhatsApp reminder, and a printable bills list
• 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: owners and office staff of cleaning companies who clean offices, clinics, buildings and villas on a monthly contract and raise one bill a month.

What it is NOT: It does not plan crews and hours: use the crew calendar for that. It does not make the invoice document or post to accounts: the invoice number is only a reference you type. Contract renewal reminders are not tracked. Check the credit rule against what each contract says. 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 (136 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 1265 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).
